abstract = {Background: Sepsis, a complex condition characterized by dysregulated immune response and organ dysfunction, is a leading cause of mortality in ICU patients. Current diagnostic and prognostic approaches primarily rely on non-specific biomarkers and illness severity scores, despite early endothelial activation being a key feature of sepsis. This study aimed to evaluate the levels of soluble thrombomodulin and soluble endoglin in seriously ill surgical septic patients and explore their association with organ dysfunction and disease severity.

Methodology: A case control study was conducted from March 2022 to November 2022, involving seriously ill septic surgical patients. Baseline clinical and laboratory data were collected within 24 h of admission to the Surgical Intensive Care Unit. This included information such as age, sex, hemodynamic parameters, blood chemistry, SOFA score, qSOFA score, and APACHE-II score. A proforma was filled out to record these details. The outcome of each patient was noted at the time of discharge.

Results: The study found significantly elevated levels of soluble thrombomodulin and soluble endoglin in seriously ill surgical septic patients. The RTqPCR analysis revealed a positive correlation between soluble thrombomodulin and soluble endoglin levels with the qSOFA score, as well as, there was a positive association between RTqPCR soluble thrombomodulin and the SOFA score. These findings indicate a correlation between these biomarkers and organ dysfunction and disease severity.

Conclusion: The study concludes that elevated levels of soluble thrombomodulin and soluble endoglin can serve as endothelial biomarkers for early diagnosis and prognostication in seriously ill surgical septic patients.},

abstract = {BACKGROUND: Chronic liver diseases (CLD) are the major public health burden due to the continuous increasing rate of global morbidity and mortality. The inherent limitations of organ transplantation have led to the development of stem cell-based therapy as a supportive and promising therapeutic option. However, identifying the fate of transplanted cells in vivo represents a crucial obstacle. AIM: To evaluate the potential applicability of DiD dye as a cell labeling agent for long-term, and non-invasive in vivo tracking of transplanted cells in the liver. METHODS: Magnetically sorted, epithelial cell adhesion molecule positive (1 × 106 cells/mL) fetal hepatic progenitor cells were labeled with DiD dye and transplanted into the livers of CLD-severe combined immunodeficiency (SCID) mice. Near-infrared (NIR) imaging was performed for in vivo tracking of the DiD-labeled transplanted cells along with colocalization of hepatic markers for up to 80 d. The existence of human cells within mouse livers was identified using Alu polymerase chain reaction and sequencing. RESULTS: NIR fluorescence imaging of CLD-SCID mice showed a positive fluorescence signal of DiD at days 7, 15, 30, 45, 60, and 80 post-transplantation. Furthermore, positive staining of cytokeratin, c-Met, and albumin colocalizing with DiD fluorescence clearly demonstrated that the fluorescent signal of hepatic markers emerged from the DiD-labeled transplanted cells. Recovery of liver function was also observed with serum levels of glutamic-oxaloacetic transaminase, glutamate-pyruvate transaminase, and bilirubin. The detection of human-specific Alu sequence from the transplanted mouse livers provided evidence for the survival of transplanted cells at day 80.

CONCLUSION: DiD-labeling is promising for long-term and non-invasive in vivo cell tracking, and understanding the regenerative mechanisms incurred by the transplanted cells. },

abstract = {Early diagnosis and prognosis of ischemic stroke remains a critical challenge in clinical settings. A blood biomarker can be a promising quantitative tool to represent the clinical manifestations in ischemic stroke. Cell-free DNA (cfDNA) has recently turned out to be a popular circulating biomarker due to its potential relevance for diagnostic applications in a variety of disorders. Despite bright outlook of cfDNA in clinical applications, very less is known about its origin, composition, or function. Several recent studies have identified cell-derived mitochondrial components including mitochondrial DNA (mtDNA) in the extracellular spaces including blood and cerebrospinal fluid. However, the time course of alterations in plasma mtDNA concentrations in patients after an ischemic stroke is poorly understood. DNA is thought to be freed into the plasma shortly after the commencement of an ischemic stroke and then gradually decreased. However, the importance of cell-free mtDNA (cf-mtDNA) in ischemic stroke is still unknown. This review summarizes about the utility of biomarkers which has been standardized in clinical settings and role of cfDNA including cf-mtDNA as a non-invasive potential biomarker of ischemic stroke.},

abstract = {BACKGROUND: Acute ischemic stroke (AIS) is one of the major causes of the continuous increasing rate of global mortality due to the lack of timely diagnosis, prognosis, and management. This study provides a primitive platform for non-invasive and cost-effective diagnosis and prognosis of patients with AIS using circulating cell-free mitochondrial DNA (cf-mtDNA) quantification and validation. AIM: To evaluate the role of cf-mtDNA as s non-invasive, and affordable tool for real-time monitoring and prognosticating AIS patients at disease onset and during treatment. METHODS: This study enrolled 88 participants including 44 patients with AIS and 44 healthy controls with almost similar mean age group at stroke onset, and at 24 h and 72 h of treatment. Peripheral blood samples were collected from each study participant and plasma was separated using centrifugation. The cf-mtDNA concentration was quantified using nanodrop reading and validated through real-time quantitative polymerase chain reaction (RT-qPCR) of NADH-ubiquinone oxidoreductase chain 1 (ND1) relative transcript expression levels. RESULTS: Comparative analysis of cf-mtDNA concentration in patients at disease onset showed significantly increased levels compared to control individuals for both nanodrop reading, as well as ND1 relative expression levels (P < 0.0001). Intergroup analysis of cf-mtDNA concentration using nanodrop showed significantly reduced levels in patients at 72 h of treatment compared to onset (P < 0.01). However, RT-qPCR analysis showed a significant reduction at 24 h and 72 h of treatment compared to the disease onset (P < 0.001). The sensitivity and specificity were relatively higher for RT-qPCR than nanodrop-based cf-mtDNA quantification. Correlation analysis of both cf-mtDNA concentration as well as ND1 relative expression with National Institute of Health Stroke Scale score at baseline showed a positive trend. CONCLUSION: In summary, quantitative estimation of highly pure cf-mtDNA provides a simple, highly sensitive and specific, non-invasive, and affordable approach for real-time monitoring and prognosticating AIS patients at onset and during treatment.},

abstract = {Introduction: Currently pulmonary fibrosis in post-COVID individuals represents a crucial milieu of investigation due to long-term associated complications and worse clinical outcome. Lack of studies in Indian population confers a crucial need for elucidating possible targets and mechanisms to explore better management and outcome. Hence, this study aimed to explore the role of circulating miRNA-21 in patients from South India after COVID-19 recovery, while targeting TGF-β signaling pathway involved in the development of pulmonary fibrosis. Methods: This prospective, single centre, hospital-based study enrolled a total of 50 participants in the age group of 50 to 60 years including 25 non-infected controls and 25 patients who were recovered after 3–6 months of COVID-19 infection and presented radiological pulmonary abnormalities. Quantification of miRNA-21 and selected gene transcripts (TGF-β, Col1A2, Col3A1, and α-SMA) was performed in plasma samples of both patients and controls. Results: Significantly increased expression levels of miRNA-21 was observed in patient samples compared to controls (4.50 ± 1.03 vs 12.60 ± 3.52, p < 0.0001) with 72.10% sensitivity and 80.10% specificity. Further, significantly increased levels of central fibrosis regulatory gene transcript TGF-β (0.56 ± 0.27 vs 1.83 ± 0.98), two crucial collagen transcripts Col1A2 (0.62 ± 0.19 vs 1.56 ± 1.00) and Col3A1 (0.61 ± 0.27 vs 1.54 ± 0.89), and α-SMA (0.46 ± 0.17 vs 1.20 ± 0.78) was observed in patients compared to controls. Western-blot analysis also showed almost similar observations at proteins levels. Conclusion: Circulating miRNA-21 may provide crucial insights for elucidating TGF-β mediated pulmonary remodeling involved in the fibrosis development and achieve better clinical outcome for post-COVID patients after recovery, in real-time with high diagnostic accuracy.},

abstract = {Background and Aim: The major aim of this study was to identify the most common stemness genes across different stem cell types and further validate them in human fetal subventricular zone-derived primary and cultured neural precursor cells (NPCs). This study involved the use of a unique method of stemness meta-analysis (SMA) for investigating comprehensive upregulation and downregulation of differentially expressed genes (DEGs) among different stem cell populations. Materials and Methods: A total of 55 mouse and human data sets targeting crucial genes identified in seven different types of stem cells population were screened and subjected to independent DEGs analysis using SMA. Identified 30 meta-gene signatures were subjected to functional enrichment analysis based on their biological processes and molecular functions. Validation of enriched meta-gene signatures was performed using RT-qPCR. Cellular localization of ABCB1 and ABCG2 was identified using immunofluorescence staining, whereas functional assessment was performed using western-blot. Results: SMA analysis revealed that among 52 commonly expressed genes, 30 genes were either upregulated or downregulated in at least two stem cell populations. Further gene enrichment analysis showed nine genes (ABCB1, ABCG2, HSPA4, HSPA9, HSPA14, Nestin, Sox-2, Oct-4, and Notch-2) with the highest combined scores among 30 meta-gene signatures. RT-qPCR demonstrated that all the enriched gene signatures were significantly upregulated in primary NPCs and further downregulated during NPCs lineage differentiation in culture except HSPA4, HSPA9, and HSPA14 gene transcripts. 

Conclusions: The stemness meta-gene signatures were abundantly expressed in human NPCs population which categorically suggest the involvement of these genes/pathways in pluripotency maintenance and molecular switches for lineage differentiation while HSP-70 had a neuroprotective effect.},

abstract = {Essential hypertension (EH) is a multifactorial, polygenic condition, and is one of the most important comorbidities that contributes to stroke, myocardial infarction, cardiac failure, and renal failure. The continuous increasing rate of morbidity and mortality associated with EH presents an unmet need of population-based studies to explore pathophysiology as well as newer strategies for better diagnosis, prognosis and treatment. This study aimed to determine genotype and allele frequencies of A1166C polymorphism of AT1R gene in Indian patients with EH and correlated with serum levels of Angiotensin II. A total of 200 patients with EH and 200 age- and gender-matched control individuals were included in this study from the General Medicine Department Outpatient at Narayana Medical College and Hospital, Nellore, Andhra Pradesh, India. Patients with systolic blood pressure (SBP) ≥ 140 mmHg and/or diastolic blood pressure (DBP) ≥ 90 mmHg were considered as hypertensive. The findings of this study revealed significantly increased risk of C/A heterozygote and allele C in both men and women. Moreover, both men and women patients with EH showed higher serum levels of Angiotensin II with C/A as well as AA genotypes. These findings indicate a significant association of 1166 C/A polymorphism of the AT1R gene with increased risk of hypertension in Indian population.},

abstract = {INTRODUCTION: Allergic asthma in children occurs in response to an allergic trigger major. In the pathophysiology of asthma, genetic variations in many loci and genes play a crucial role. Genes of DNA repair pathways have been well characterized in association with clinical pathologies of different forms of allergic asthma with conicting outcomes. This study reports the role of single nucleotide polymorphisms (SNPs) in X-ray cross-complementing group 1 (XRCC1) and apurinic/apyrimidinic endonuclease 1 (APE1)polymorphisms in pediatric patients with food and air born allergen asthma. METHODS: 125 pediatric asthma patients and age and gender matched 164 controls were enrolled. Blood samples were collected after conrming the food and air allergen related asthma. Genomic DNA was isolated from whole blood and genotyping was done for XRCC1 Arg399Gln and APE1 Asp148Glu using ARMS-PCR. RESULTS: The frequency of genotype Arg399Gln (heterozygous) of XRCC1 gene was signicantly higher in patients with allergic asthma than the controls (odds ratio [OR] 2.75; 95% condence interval [CI] 1.69 -4.47; p=0.006). 'A' allele of XRCC1 gene was found to be predominant in pediatric asthma group compared to controls. Similarly the genotype TG frequency of APE1 Asp148Glu showed statistically signicant change in allergic asthma patients compare to controls (OR 2.93; 95% CI 1.77-4.85; p<0.001). 'G' allele of APE1 gene was found predominantly in pediatric asthma group compared to controls. CONCLUSION: Polymorphisms in XRCC1 Arg399Gln and APE1 Asp148Glu signicantly increased the risk of allergic asthma in pediatric patients.},

abstract = {Despite increasing burden of autoimmune thyroid disease (AITD) in India, there is paucity of data for the genetic susceptibility in Indian population which represents an important aspect to uncover the genetic factors for the cause or progression of different forms of AITD. It is known that production of auto-antibodies to thyroglobulin (TG) and thyroid peroxidase (TPO) is a characteristic feature of AITD. Production of high titres of auto-antibodies against TG and TPO is one the hallmarks of AITD that often precedes the development of clinical disease. The gene coding for cytotoxic T lymphocyte antigen-4 (CTLA-4) is considered an important candidate gene for susceptibility to AITD and also determines seropositivity. Earlier studies have demonstrated that polymorphic variants in CTLA-4 gene are linked to determine seropositivity. Hence, this study investigates a relationship between CTLA-4 (+49A/G) genotypes and seropositivity to anti-TPO and anti-TG antibodies in AITD patients. A total of 85 Indian participants were included and genotyped for CTLA-4 (+49A/G) single nucleotide polymorphism and further analyzed for seropositivity of TPO and TG auto-antibodies in mean age group of 35.76 ± 12.42 years of both the genders. The TPO seropositivity was reported higher in G allele containing genotypes GG and AG (66.66% and 58%, respectively) compared to AA (44.8%) genotype. Whereas, TG auto-antibodies showed highest seropositivity for genotype AA (55.17%) compared to AG (36%) and GG (16.6%). Higher median titre values were observed for TPO antibodies with GG genotype (1587.461 U/mL). In contrast to this, higher titres of auto-antibodies to TG were observed for individuals with AA genotype (520.746 U/mL). In conclusion, this study demonstrates a relationship between CTLA4 (+49A/G) genotype and seropositivity to thyroid auto antigens TPO and TG in Indian patients with clinical manifestation of Hashimoto's thyroiditis and Graves' disease, two different forms of AITD.},

abstract = {Introduction: The reconstruction/regeneration of human bone injuries/defects represents a crucial challenge due to the lack of suitable bio/immune compatible and implantable biological grafts. The available strategies represent implications of several types of grafting materials in the form of metals, synthetic, and various kinds of biological scaffolds; however, the lack of appropriate biological components required for activating and enhancing repair mechanisms at the lesion-site limits their wider applicability. Methods: In this study, a unique approach for generating human osteogenic implantable grafts was developed using biofabrication technology. Using a gradient change of detergents and continuous agitation, developed a unique technique to generate completely cell-free amnion and chorion scaffolds. The absence of cellular components and integrity of biological and mechanical cues within decellularized human amnion (D-HAM) and chorion (D-HCM) were evaluated and compared with fresh membranes. Allogenic bone grafts were prepared through induction of human mesenchymal stem cells (hMSCs) into osteogenic cells on D-HAM and D-HCM and evaluated for their comparative behavior at the cellular, histological and molecular levels. Results: The common decellularization process resulted in an efficient way to generate D-HAM and D-HCM while retaining their intact gross-anatomical architecture, surface morphology, extracellular matrix components, and mechanical properties. Both these scaffolds supported better growth of human umbilical cord blood derived MSCs as well as osteogenic differentiation. Comparative investigation revealed better growth rate and differentiation on D-HCM compared to D-HAM and control conditions. Conclusion: D-HCM could be used as a better choice for producing suitable allogenic bone grafts for efficient bone healing applications. },

However, the low engraftment efficiency and obscurity to harvest these cells without compromising the cellular viability, structural and functional properties from the culture niche still remain major obstacles for preparing intact regenerative constructs. Although few studies have demonstrate different methods for generating cell-liberated amniotic scaffolds, a common method for producing completely cell-liberated amnion (D-HAM) and chorion (D-HCM) scaffolds and their cytocompatibility with hMSCs yet to be demonstrated. Methods: A common process was developed for preparing D-HAM and D-HCM scaffolds for assessing hMSCs engraftment efficiency, proliferation and molecular shifts to generate cell-laden biological discs. The structural and functional integrity of D-HAM and D-HCM was evaluated using different parameters. The compatibility and proliferation efficiency of hMSCs with D-HAM and D-HCM was evaluated. Results: 

Histological analysis revealed completely nucleic acid-free D-HAM and D-HCM scaffolds with intact extracellular matrix, mechanical and biological properties almost similar to the native membranes. Human MSCs were able to adhere and engraft on D-HCM better than D-HAM and expanded faster. Ultrastructural observations, crystal violet staining and expression studies showed better structural and functional integrity of hMSCs on D-HCM than D-HAM and control conditions. Conclusion: A common, simple and reliable process of decellularization can generate large number of cell-liberated amniotic scaffolds in lesser time. D-HCM has better efficiency for hMSCs engraftment and proliferation and can be utilized for preparing suitable cell-laden constructs for tissue engineering applications.},

abstract = {Migraine is a primary headache disorder marked by recurrent unilateral headache episodes. Calcitonin gene related peptide (CGRP) plays major role in migraine pathophysiology. CGRP is multifunctional, and its vasodilating activity within the central and peripheral blood vessels is one in all its primary functions.The intention is to prove serum calcitonin gene related peptide (CGRP) as an early diagnostic tool for migraine and the novelty is to correlate it with characteristics of migraine so that it helps in early initiation of treatment.

Methods. 100 subjects including 90 patients with migraine and 10 with non-headache (NH) age-matched controls were prospectively recruited in our current study. The subjects were aged from 15- 50 years. The clinical assessment was made every month for the three months after the start of therapy. The subjects were compared based on the serum CGRP values. Serum CGRP concentrations were measured by using CGRP ELISA kit. Results. Out of total subjects selected, the maximum (23.3%) subjects were between age 26 and 30 years and least effected age group was 46-50 years (4.44%). Females’ predominance with 82% than males with 18%.Stress was major trigger occurring in 57% of cases. Throbbing pain with elevated CGRP levels 130.44±114.22 and p value (p = 0.01). The average CGRP levels was higher in test group 149.00±93.86 compared to control 61.30±24.37 with p value (p = 0.02). Conclusions. The serum CGRP levels were statistically more in migraine patients correlated with characteristics like throbbing type of pain, stress and inadequate sleep. Hence, the serum CGRP levels estimation can be considered as a diagnostic tool for migraine when the clinical character’s over lap or early in the course of migraine when all criteria for diagnosis are not yet fulfilled.},

Methods: A systematic literature review of Medline®, EMBASE® and Cochrane library was performed to identify studies reporting efficacy and safety of NSCT in SCI. Articles were included if they reported efficacy and safety data of SCI patients who received NSCT. Results: Overall, four studies of the 277 records met all the study eligibility criteria. Over the 1-year follow-up period, motor scores were significantly higher among patients who received NSCT compared with those who did not (American Spinal Injury Association [ASIA] motor scores (mean ± standard deviation [SD]): 7.9 ± 1.2 versus 3.9 ± 0.6; upper extremity motor score: 7.8 ± 2.1 versus 3.9 ± 0.6, both P < 0.05). Sensory scores (pinprick score: 4.8 ± 1.3 versus 2.9 ± 0.6; P = 0.5; light touch score: 6.9 ± 3.1 versus 2.3 ± 0.5, P = 0.3), ASIA impairment scale (26% versus 7%) or pain score (baseline: 2.4 ± 0.6; 1-year: 3.4 ± 0.4) were comparable in both NSCT and non-NSCT cohorts. Over the 1-year follow-up period, the graded redefined assessment of strength, sensibility, and prehension and international standards for neurological classification of SCI scores showed a mean improvement of 14.8 and 17.8 points respectively. Overall, treatment with NSCT showed favorable safety and tolerability profile. Conclusions: Due to the limited and poor-quality evidence, it is too early to make robust conclusions on the efficacy of NSCT in the treatment of SCI. However, based on the included studies, NSCT seems to be a potential option worth exploring among patients with SCI. Nonetheless, prospective, randomized trials in larger cohorts are needed to validate the efficacy and safety of NSCT in the treatment of SCI.},

abstract = {Introduction: Bladder dysfunction has been considered as one of the most critical health conditions with no proper treatment. Current therapeutic approaches including enterocystoplasty have several limitations. Hence, biofabrication of cell-laden biological allografts using decellularized Goat urinary bladder scaffolds for organ reconstruction/regeneration was major objective of this study. Materials and methods: An efficient method for decellularization of Goat urinary bladder (N = 3) was developed by perfusion of gradient change of detergents through ureter. The retention of organ architecture, extracellular matrix composition, mechanical properties and removal of cellular components was characterized using histological, cellular and molecular analysis. Further, mesenchymal stem cells (MSCs) from human umbilical cord blood (UCB) were used for preparing biological construct of decellularized urinary bladder (DUB) scaffolds to augment the urinary bladder reconstruction/regeneration. Results: The decellularization method adopted in this study generated completely DUB scaffolds within 10 h at 100 mm Hg pressure and constant flow rate of 1 mL/min. The DUB scaffold retains organ architecture, ECM composition, and mechanical strength. No significant amount of residual nucleic acid was observed post-decellularization. Furthermore, MSCs derived from human UCB engrafted and proliferated well on DUB scaffolds in highly aligned manner under xeno-free condition. Conclusion: Biofabricated humanized urinary bladder constructs provides xeno-free allografts for future application in augmenting urinary bladder reconstruction/regeneration with further development.},

As it is associated with quantitative variations in IL-4 gene expression and may serve as an important candidate gene for asthma risk prediction. Objective: To investigate the polymorphic variations, at -590 (C/T) in the promoter region of IL-4 gene. Methods: 50 consecutively selected cases of asthma (36 females and 14 males) were recruited and genotyping for SNP at -590 C/T was done by PCR-RFLP method on the genomic DNA extracted from blood samples. Blood samples from 50 randomly selected healthy subjects served as controls. Mean values of Absolute Eosinophil Count and total serum IgE between the genotypes were compared by student’s unpaired t test. Odds-ratio analysis was carried out to determine risk of developing asthma. Results: Odds ratio (OR) analysis revealed two-and-a-half folds increased risk of asthma for individuals with TT genotype compared to those with CC genotype. A decreased frequency of CC genotype in patients (28%) compared to controls (58%) is indicative of protective nature of CC genotype. AEC counts and total serum IgE levels were significantly higher in TT compared to CC and CT genotypes. Conclusion: It is concluded that individuals with TT and CT genotypes (overproducers of IL-4) have high risk of developing asthma and high vulnerability to develop chronic airway remodeling.},

abstract = {Excess fluoride intake has been linked with various pathological conditions. The objective of the present study was to understand the role of fluoride in neurotoxic, neuroinflammatory, and neurodegenerative changes in the brain tissue of Wistar rats. Wistar rats were fed with water containing 20–100 ppm (ppm) sodium fluoride (NaF). An array of neurotransmitters (acetylcholine, dopamine, epinephrine, norepinephrine, serotonin, histamine, and glutamate) expression levels were estimated with respect to different fluoride concentrations. Additionally, its effect on the expression levels of specific neuroinflammatory markers (iNOS, COX-2, TNF-α, PKC, VEGF, and HSP-70) in brain tissues of Wister rats was assessed. An increase in NaF concentration resulted in increased fluoride deposition in the brain which in turn caused increase levels of epinephrine, histamine, serotonin, and glutamate and decreased levels of norepinephrine, acetylcholine, and dopamine in a dose-dependent manner. Tissue fluoride levels of the hippocampus, neocortex, cerebellum, spinal cord, and sciatic nerve increased significantly in fluoride fed rats. Transmission electron microscopy in the experimental animals revealed axon deterioration, myelin sheath degeneration, and dark cells with scanty cytoplasm in the spinal cord and sciatic nerve. Additionally, vacuolated swollen mitochondria were observed in the neocortex, hippocampus, and cerebellum. Results suggest excess fluoride intake modulates a set of biological marker and promote neuroinflammatory and neurodegenerative condition in Wister rats. Therefore, we conclude that the accumulation of NaF alters the neurological function which leads to neurodegenerative disorders.},

The current study investigated the effect of H. pylori genotypes in the outcome of disease, and the expression of anti-apoptotic related genes, COX-1, COX-2, and iNOS genes in benign, pre-malignant, and malignant lesions of gastric carcinogenesis. Materials and methods: Tissue samples from H. pylori positive patients were graded based on the genotype of the infected H. pylori strain. Expression of COX-1, COX-2 and iNOS was assessed using a combination of real-time PCR and immunohistochemistry. Results: Gene expression studies confirmed that COX-2 and iNOS expression was highly and selectively induced in epithelium with premalignant changes such as atrophic conditions, metaplasia and dysplasia, suggesting an important role of these genes in the sequence to gastric carcinoma of the intestinal type. Furthermore, the expression of COX-2 and iNOS was also dependent on the genotype of H. pylori and subjects with genotype-1 exhibited significantly higher expressions of COX-2 and iNOS compared to other genotypes. Comparison of the expression levels among infected and uninfected individuals demonstrated significant difference in the expression pattern of COX-2 gene whereas iNOS expression was found only in subjects infected H. pylori (p < 0.001). Immunohistochemical staining showed 1.5619 folds higher propensity of COX-2 and 3.2941 folds higher intensity of iNOS expression in subjects infected with H. pylori genotype 1. Conclusion: The up-regulation of COX-2 and iNOS was associated with the genotype of the H. pylori strain and the presence of certain genotype may greatly affect early events during carcinogenesis.},

abstract = {Acute liver failure (ALF) is one of the most devastating fatal conditions which have posed crucial challenges to the clinicians and researchers for identifying permanent cure. Currently liver transplantation has been considered as the only managerial option. However it's wider applicability has been limited owing to non-availability of quality donor organs, cost-intensiveness, surgical hitches, life-long use of immunosuppressive drugs and long-term complications. Since last decades, several liver support systems have been developed for the management of failing liver in acute condition. However, the major limitation has been the lack of natural biological support and long-term survival of the grafts post-transplantation. Repopulation of decellularized xenogeneic organs is one of the emerging technologies for development of humanized neo-organs for demanding regenerative application. However, the earlier reported studies do not fulfil the insistence to provide immunologically tolerable humanized liver grafts for clinical applications. Here we demonstrate an efficient approach to generate transplantable humanized liver grafts which provides long-term support to the failing liver in Acute Liver Failure (ALF) animal models. These bioengineered humanized liver tissue grafts expresses several liver specific transcripts and performed crucial synthetic (albumin production) and detoxification (urea synthesis) functions at comparative level to normal liver. Intraperitoneal transplantation of these humanized liver grafts offered favourable microenvironment to exchange toxic substances across the barrier during ALF condition and provided long-term survival and function of the graft. In summary, the results of present study provide a first proof of concept in pre-clinical ALF animal model for the applicability of these bioengineered humanized livers in the management of failing liver on demand and may be considered as potential bridge to liver transplantation.},

abstract = {Spinal cord injury (SCI) is one of the most precarious conditions which have been one of the major reasons for continuous increasing mortality rate of SCI patients. Currently, there is no effective treatment modality for SCI patients posing major threat to the scientific and medical community. The available strategies don't mimic with the natural processes of nervous tissues repair/regeneration and majority of the approaches may induce the additional fibrotic or immunological response at the injury site and are not readily available on demand. To overcome these hurdles, we have developed a ready to use bioengineered human functional neurological construct (BHNC) for regenerative applications in SCI defects. We used cryopreserved meningeal tissues (CMT) for bioengineering these neurological constructs using acellularization and repopulation technology. The technology adopted herein generates intact neurological scaffolds from CMT and retains several crucial structural, biochemical and mechanical cues to enhance the regenerative mechanisms. The neurogenic differentiation on CMT scaffolds was almost similar to the freshly prepared meningeal scaffolds and mimics with the natural nervous tissue developmental mechanisms which offer intact 3D-microarchitecture and hospitable microenvironment enriched with several crucial neurotrophins for long-term cell survival and function. Functional assessment of developed BHNC showed highly increased positive staining for pre-synaptic granules of Synapsis-1 along with MAP-2 antibody with punctuate distribution in axonal regions of the neuronal cells which was well supported by the gene expression analysis of functional transcripts. Given the significant improvement in the field may enable to generate more such ready to use functional BHNC for wider applicability in SCI repair/regeneration.},

We analyzed the association between CTLA-4 rs231775 and FOXP3 rs3761548, rs3761549 polymorphisms and predisposition to autoimmune thyroid disease (AITD), inclusive of Hashimoto’s thyroiditis (HT) and Graves’ disease (GD) in South-Indian population. Methods: A total of 355 AITD subjects (comprising 275 HT and 80 GD) and 285 randomly selected age- and sex-matched control subjects were genotyped for the aforementioned polymorphisms by PCR-RFLP method. Results: The rs231775 “G” allele was preponderant in HT and GD subjects when compared with controls and exerted a dominant influence on the susceptibility to HT (p = 0.009) and GD (p = 0.02), respectively. There was no allelic association of rs3761548 and rs3761549 polymorphisms with AITD susceptibility, albeit a significant difference in genotype distribution with respect to rs3761549. Haplotype analysis revealed an increased frequency of rs3761548 “C”–rs3761549 “T” in HT and GD subjects, thereby associating it with disease predisposition (p = 0.03). Epistatic interaction analysis by multifactor dimensionality reduction approach revealed redundancy between CTLA-4 and FOXP3 genes in influencing the susceptibility to AITD. Conclusions: The genetic variation in CTLA-4 gene with reference to rs231775 polymorphism contributes to an increased predisposition to HT and GD. Also, in conjunction with FOXP3 gene variants it seems to influence the susceptibility to HT and GD respectively. The significance of these findings in combination with antithyroid antibody screening could plausibly contribute towards meticulous case-finding for effective treatment of HT and GD.},

abstract = {Immune cells sense and programme its cellular machinery appropriately to the environmental changes through the activation of cytoprotective adaptive pathway so-called the “integrated stress response (ISR)”. However, the mechanisms implicated in ISR-induced protective responses are poorly understood. Here, we show that ISR activation by arsenite (Ar) results in suppression of IL-1β production in macrophages and inhibition of DSS-induced colitis in a murine model through a novel posttranscriptional and translation regulatory (PTR) mechanism. Ar triggers PTR events through eIF2α-phosphorylation, which results in the attenuation of active polysome formation leading to the accumulation of translationally stalled IL-1β mRNAs. Translationally stalled IL-1β mRNAs recruit RNA-binding proteins (TIA-1/TIAR), resulting in the formation of RBP-RNA complexes known as stress granules (SGs). The SGs bound IL-1β mRNAs might undergo degradation through induction of autophagy. Also, we show that Ar posttranslationally impairs processing and secretion of IL-1β by diminishing inflammasome activation. Altogether, this study unveils a novel mechanism of IL-1β regulation and further suggests that pharmacological activation of cytoprotective ISR pathway might provide an effective therapeutic intervention against inflammatory diseases.},

Cell viability and proliferative efficiency were tested with cell adhesion and MTT assay. Osteo/odontogenic differentiation was assessed and quantified with alizarin red staining. Results: MTA alone, MTA with 5% PRP, and MTA with 10% PRP showed significantly high proliferation at day 7 and 14 when compared to the control group. Enhanced differentiation and the highest calcium deposition was observed in MTA with the 10% PRP group. Conclusion: Within limitations of the in vitro environment, results imply an increased proliferation and induction of MSCs into osteo/odontogenic differentiation by the combination rather than a mere sealing of PRP by MTA. Clinical significance: PRP and MTA have the potential for true regeneration of the pulp tissue. Moreover, the combination of PRP and MTA can 

be utilized to expand the MSCs to generate adequate numbers for clinical applications, without xenogenic contamination.},

abstract = {End stage liver diseases (ESLD) represent a major, neglected global public health crisis which requires an urgent action towards finding a proper cure. Orthotropic liver transplantation has been the only definitive treatment modality for ESLD. However, shortage of donor organs, timely unavailability, post-surgery related complications and financial burden on the patients limits the number of patients receiving the transplants. Since last two decades cell-based therapies have revolutionized the field of organ/tissue regeneration. However providing an alternative organ source to address the donor liver shortage still poses potential challenges. The developments made in this direction provide useful futuristic approaches, which could be translated into pre-clinical and clinical settings targeting appropriate applications in specific disease conditions. Earlier studies have demonstrated the applicability of this particular approach to generate functional organ in rodent system by connecting them with portal and hepatic circulatory networks. However, such strategy requires very high level of surgical expertise and also poses the technical and financial questions towards its future applicability. Hence, alternative sites for generating secondary organs are being tested in several types of disease conditions. Among different sites, omentum has been proved to be more appropriate site for implanting several kinds of functional tissue constructs without eliciting much immunological response. Hence, omentum may be considered as better site for transplanting humanized bioengineered ex vivo generated livers, thereby creating a secondary organ at intra-omental site. However, the expertise for generating such bioengineered organs are limited and only very few centres are involved for investigating the potential use of such implants in clinical practice due to gap between the clinical transplant surgeons and basic scientists working on the concept evolution. Herein we discuss the recent advances and challenges to create functional secondary organs through intra-omental transplantation of ex vivo generated bioengineered humanized livers and their further application in the management of ESLD as a supportive bridge for organ transplantation.},

The restoration of structural and functional aspect of damaged neurological tissues at the lesion site in spinal cord has been challenging. Recent developments have showed tremendous potential of neural stem cell-based strategies to form a neuronal relay circuit across the injury gap which facilitates some levels of improvement in SCI condition. However, to provide better therapeutic responses, critical mass of grafted cells must survive for long-term and differentiate into neuronal cells with well-developed axonal networks. Hence, development of tissue specific biological neuronal constructs is highly desirable to provide mechanical and biological support for long-term survival and function of neurological cells within natural biological niche. In this study, we report development of a tissue specific neuronal constructs by culturing human neural precursor cells on decellularized meningeal scaffolds to provide suitable biological neuronal construct which can be used to support mechanical, structural and functional aspect of damaged spinal cord tissues. This particular tissue specific biological construct is immunologically tolerable and provides precisely orchestral three-dimensional platform to choreograph the long-distance axonal guidance and more organized neuronal cell growth. It passes sufficient mechanical and biological properties enriched with several crucial neurotrophins required for long-term survival and function of neurological cells which is required to form proper axonal bridge to regenerate the damaged axonal connectomes at lesion-site in SCI.},

The acellularized xenogeneic spleen scaffold was characterized thoroughly for preservation of extra-cellular matrix and retention of organ specific vasculature and mechanical properties. Further scaffolds were sterilized and repopulated with hHPCs which were triggered using a stage wise induction with growth factors and hyperglycemic challenge for trans-differentiation into InPCs. Dynamics of pTFs alone or simultaneously during induction process was identified using gene expression analysis and immunological staining. Results: The cells within the engineered neoorgan respond to growth factors and extrinsic hyperglycemic challenge and generate large number of InPCs under controlled dynamic regulation of pTFs. Highly controlled regulation of pTFs generates higher percentage of Nkx-6.1+/C-peptide+ cells within the engineered splenic scaffolds. Generation of high percentage of insulin and C-peptide positive cells in three-dimensional organ architecture responded better to hyperglycemic stimuli and produced higher quantity of insulin than 2D-culture system. Conclusion: The present study provides a novel platform for designing effective regenerative strategies using whole organ scaffolds to control hyperglycemia under tight regulation of pTFs using humanized neoorgan system.},

abstract = {Ulcerative colitis (UC) is a persistent inflammatory illness, which is clinically categorised as Inflammatory bowel disease (IBD), affecting millions of people worldwide. The precise cause behind the pathology of the disease remains unknown. However, the involvement of multiple factors including genetic predisposition, immunological deregulations, microbiota imbalance, and environmental triggers has been suggested. Amongst all these factors, the over-active immunological response reported in UC patients seems to be a promising target for therapy. Moreover, identification of gene signatures associated with disease onset and progression would help in better understanding of the molecular mechanisms involved in the disease pathogenesis. Here, we have conducted meta-analysis of gene expression profiles of UC patient microarray datasets accessible in public databases and further validated the in-silico findings in UC patients’ blood samples. Our study reveals that UC pathogenesis perturbs expression of several inflammatory genes. In addition, we report a novel gene signature comprising of TIA1 (T cell restricted intracellular antigen) and TIAR (TIA1 related protein; also known as TIAL1), which were found to be significantly downregulated in UC patients. TIA1 and TIAR are RNA-binding proteins (RBPs), which function as a translational represser by binding to ARE sequences in the 3′ UTR of mRNAs encoding inflammatory mediators including cytokines. Our findings demonstrate that deletion of TIAR using gene specific siRNAs in-vitro results in enhanced production of inflammatory cytokine IL-1β. In conclusion, the findings of this study reveal that down regulation of TIA1/TIAR genes could be responsible for UC associated inflammation. This study highlights the usefulness of the meta-analysis approach in the identification of unique gene signatures that might deliver mechanistic insights into UC pathogenesis and possibly assist in discovery of prognostic markers and therapeutic interventions.},

abstract = {BACKGROUND:Gold nanoparticles (GNPs) are key diagnostic and therapeutic agents in biomedical sciences. Several studies have been carried out in different therapeutic areas such as in cancer treatment, antibacterial topical agents, imaging agents etc. There is a necessity to evaluate the gold nanoparticles cytotoxicity at all fronts. Since blood is the first point of contact in any therapy, it is required to have a thorough in vitro investigation of gold nanoparticles to avoid any adverse effects. OBJECTIVE:The objective of the current study is to evaluate the effect of gold nanoparticles capped with lipase on blood clotting factors, platelets, coagulation time and blood clotting strength. METHODS:Whole blood samples were drawn from healthy volunteers. Plasma and plasma with platelets were isolated from the blood and all the samples were treated with lipase capped gold nanoparticles, except control. Plasma fibrinogen formed in the blood coagulation process after contacting with nanoparticles was quantitatively evaluated. In addition, platelet aggregation, blood clotting kinetics, strength of the blood clot and time were evaluated post nanoparticle treatment. RESULTS:The work primarily explores the effect of GNPs on blood with changing concentrations of lipase capping. Plasma fibrinogen levels of plasma samples were found to be moderately elevated, however, there is no significant effect on blood clotting kinetics, strength, and platelet aggregation. Also, the study showed that lipase capped GNPs did not result in aggregation upon interaction with plasma components and remained stable for 1 hour after incubation. CONCLUSIONS:Our study revealed that lipase capped GNPs synthesized using NaBH4 approach were stable and hemocompatible. There is an increase in fibrinogen levels after the exposure to nanoparticles, an observation which is consistent with other studies. However, the functional consequences of such increase are unknown. The results of no significant platelet aggregation, change in blood clotting time, kinetics, and clot strength revealed the non-toxic effect of lipase capped GNPs towards blood components, which is essential for any in vivo applications.},

abstract = {Activation of the amino acid starvation response (AAR) increases lifespan and acute stress resistance as well as regulates inflammation. However, the underlying mechanisms remain unclear. Here, we show that activation of AAR pharmacologically by Halofuginone (HF) significantly inhibits production of the proinflammatory cytokine interleukin 1β (IL-1β) and provides protection from intestinal inflammation in mice. HF inhibits IL-1β through general control nonderepressible 2 kinase (GCN2)–dependent activation of the cytoprotective integrated stress response (ISR) pathway, resulting in rerouting of IL-1β mRNA from translationally active polysomes to inactive ribocluster complexes—such as stress granules (SGs)—via recruitment of RNA-binding proteins (RBPs) T cell–restricted intracellular antigen-1(TIA-1)/TIA-1–related (TIAR), which are further cleared through induction of autophagy. GCN2 ablation resulted in reduced autophagy and SG formation, which is inversely correlated with IL-1β production. Furthermore, HF diminishes inflammasome activation through suppression of reactive oxygen species (ROS) production. Our study unveils a novel mechanism by which IL-1β is regulated by AAR and further suggests that administration of HF might offer an effective therapeutic intervention against inflammatory diseases.},

Earlier studies have provided very limited mechanistic insights of cellular and molecular mechanisms which do not mimic with human situation due to varying cell types and poses potential challenges for investigation. Therefore, the present study was undertaken to evaluate the role of ABC transporters and heat shock proteins mediated response in human neural precursor cells (NPCs) and its lineages during proliferation and lineage differentiation against ethanol exposure. Methods: Effect of ethanol exposure was examined for neuronal cell survival and variation in cellular phenotype during neurospheres development and lineage differentiation. Generation of reactive oxygen species, and variation in cell cycle was identified along with transcriptional profiling for pluripotent markers (Nestin, NCAM, Sox-2, and Notch-2), drug transporters (ABCB1 and ABCG2) and stress protein (HSP70) during ethanol exposure. Results: ABC transporters as well as HSP70 mRNA expression was higher during proliferation as compared to differentiation with chronic ethanol (1 M) exposure (p < 0.01). Ethanol exposure resulted in higher variability in size and shape of developing neurospheres and decreased ability to form new neurosphere colonies. Significant changes were observed in dendrite development due to late ethanol exposure (p < 0.0001). Conclusion: The present study demonstrated significant role of ABC transporters and HSP70 proteins in providing defense against ethanol-induced damage in human neurological cells. However, the over-expression of ABC transporter and HSP-70 proteins during such pathological conditions do not provide complete defense and additional strategies are required to repair the damage.},

METHODS: Bioengineered humanized livers were developed in this study using human hepatic stem cells repopulation within the acellularized liver scaffolds which mimics with the natural organ anatomy and physiology. Six cytochrome P-450 probes were used to enable efficient identification of drug metabolism in bioengineered humanized livers. The drug metabolism study in bioengineered livers was evaluated to identify the absorption, distribution, metabolism, excretion and toxicity responses. RESULTS: The bioengineered humanized livers showed cellular and molecular characteristics of human livers. The bioengineered liver showed three-dimensional natural architecture with intact vasculature and extra-cellular matrix. Human hepatic cells were engrafted similar to the human liver. Drug metabolism studies provided a suitable platform alternative to available ex-vivo and in vivo models for identifying cellular and molecular dynamics of pharmacological drugs. CONCLUSION: The present study paves a way towards the development of suitable humanized preclinical model systems for pharmacological testing. This approach may reduce the cost and time duration of preclinical drug testing and further overcomes on the anatomical and physiological variations in xenogeneic systems.},

The present study has aimed to unearth the role of valproic acid (VPA) and mild hypothermia (MH) as promising strategy to enhance the neuroprotective mechanisms in undifferentiated and differentiated human neural precursor cells (hNPCs) against ethanol-induced damage. Methods: 5 mM VPA alone or in combination with MH (33 °C) was used to prevent the damage in proliferating and differentiating hNPCs. CD133 + ve enriched hNPCs were cultured in vitro and exposed to 1 M chronic ethanol concentration for 72 h and followed by VPA and MH treatment for 24 h. Morphometric analysis was performed to identify changes in neurospheres development and neuronal cell phenotypes. Flow cytometry and RT-qPCR analysis was performed to investigate alterations in key molecular pathways involved in cell survival and signaling. Results: Combination of VPA with MH displayed higher proportion of neuronal cell viability as compared to single treatment. Combination treatment was most effective in reducing apoptosis and reactive oxygen species levels in both the undifferentiated and differentiated hNPCs. VPA with MH significantly improved neuronal cell phenotype, active chromatin modeling, chaperon and multi-drug resistant pumps activity and expression of neuronal signaling molecules. Conclusion: The study provided an efficient and disease specific in vitro model and demonstrated that combined treatment with VPA and MH activates several neuroprotective mechanisms and provides enhanced protection against ethanol-induced damage in cultured undifferentiated and differentiated hNPCs.},

abstract = {Background: Alcohol consumption is the fourth leading cause of death and disability worldwide. Several cellular pathways contribute to alcohol-mediated tissue injury. Adipose tissue apart from functioning as an endocrine organ secretes several hormones and cytokines known as adipokines that are known to play a significant role in alcohol-induced tissue damage. This study was designed to test the efficacy of diallyl sulfide (DAS) in regulating the alcohol-induced outcomes on adipose tissue. Methods: Male Wistar rats were fed with 36% Lieber–DeCarli liquid diet containing ethanol (EtOH) for 4 weeks. Control rats were pair-fed with isocaloric diet containing maltodextrin instead of EtOH. During the last week of feeding protocol, the EtOH-fed rat group was given 200 mg/kg body weight of DAS through diet. We also studied DAS effect on isolated human primary adipocytes. Viability of human primary adipocytes on DAS treatment was assessed by MTT assay. Malondialdehyde (MDA), a marker of oxidative stress, was measured by HPLC and the thiobarbituric acid method. Expression of inflammatory genes and lipogenic genes was studied by qRT-PCR and Western blotting. Serum inflammatory gene expression was studied by ELISA. Results: Our study results showed that DAS could alleviate EtOH-induced expression levels of proinflammatory and endoplasmic reticulum (ER) stress genes and improve adipose tissue mass and adipocyte morphology in male Wistar rats fed Lieber–DeCarli diet containing 6% EtOH. Further, we showed that DAS reduced the expression of lipogenic genes and improved lipid accumulation and adipocyte mass in human primary adipocytes treated with EtOH. Subsequently, we also showed that oxidative stress, as measured by the changes in MDA levels, was reduced in both male Wistar rats and human primary adipocytes treated with EtOH plus DAS. Conclusions: Our study results prove that DAS is effective in ameliorating EtOH-induced damage to adipose tissue as evidenced by the reduction brought about by DAS in oxidative stress, ER stress, and proinflammatory gene expression levels. DAS treatment also regulated lipogenic gene expression levels, thereby reducing free fatty acid release. In conclusion, this study has clinical implications with respect to alcohol-induced adipose tissue injury among alcohol users.},

abstract = {Rheumatoid arthritis (RA), a symmetric polyarticular arthritis, has long been feared as one of the most disabling forms of arthritis. Identification of gene signatures associated with RA onset and progression would lead toward development of novel diagnostics and therapeutic interventions. This study was undertaken to identify unique gene signatures of RA patients through large-scale meta-profiling of a diverse collection of gene expression data sets. We carried out a meta-analysis of 8 publicly available RA patients’ (107 RA patients and 76 healthy controls) gene expression data sets and further validated a few meta-signatures in RA patients through quantitative real-time PCR (RT-qPCR). We identified a robust meta-profile comprising 33 differentially expressed genes, which were consistently and significantly expressed across all the data sets. Our meta-analysis unearthed upregulation of a few novel gene signatures including PLCG2, HLA-DOB, HLA-F, EIF4E2, and CYFIP2, which were validated in peripheral blood mononuclear cell samples of RA patients. Further, functional and pathway enrichment analysis reveals perturbation of several meta-genes involved in signaling pathways pertaining to inflammation, antigen presentation, hypoxia, and apoptosis during RA. Additionally, PLCG2 (phospholipase Cγ2) popped out as a novel meta-gene involved in most of the pathways relevant to RA including inflammasome activation, platelet aggregation, and activation, thereby suggesting PLCG2 as a potential therapeutic target for controlling excessive inflammation during RA. In conclusion, these findings highlight the utility of meta-analysis approach in identifying novel gene signatures that might provide mechanistic insights into disease onset, progression and possibly lead toward the development of better diagnostic and therapeutic interventions against RA.},

Aims: Exploration of the expression profile of several key molecular markers to evaluate the molecular dynamics in undifferentiated and differentiated DP-derived stem cells (DPSCs) in vitro. Settings and Design: The characteristics and multilineage differentiation ability of DPSCs were determined by cellular and molecular kinetics. DPSCs were further induced to form adherent (ADH) and non-ADH (NADH) neurospheres under serum-free condition which was further induced into neurogenic lineage cells and characterized for their molecular and cellular diversity at each stage. Statistical Analysis Used: Statistical analysis used one-way analysis of variance, Student's t-test, Livak method for relative quantification, and R programming. Results: Immunophenotypic analysis of DPSCs revealed >80% cells positive for mesenchymal markers CD90 and CD105, >70% positive for transferring receptor (CD71), and >30% for chemotactic factor (CXCR3). These cells showed mesodermal differentiation also and confirmed by specific staining and molecular analysis. Activation of neuronal lineage markers and neurogenic growth factors was observed during lineage differentiation of cells derived from NADH and ADH spheroids. Greater than 80% of cells were found to express β-tubulin III in both differentiation conditions. Conclusions: The present study reported a cascade of immunophenotypic and molecular markers to characterize neurogenic differentiation of DPSCs under serum-free condition. These findings trigger the future analyses for clinical applicability of DP-derived cells in regenerative applications.},

abstract = {Oxidative stress is considered as one of the important mechanism in the causation of type 2 diabetes (T2DM) as well as cardiovascular diseases. Quantification of serum malondialdehyde (MDA) is generally employed as

reliable marker of assessment of oxidative stress. The objective of the present study was to estimate serum MDA levels in acute myocardial infarction cases with and without T2DM. A total of 60 AMI patients were studied, including 30 cases of AMI with T2DM and an equal number of cases of AMI without T2DM. Mean serum levels of MDA were 543.17± 56.97 and 423.50 ± 51.12 nmol/dL respectively in cases of AMI with T2DM and those without T2DM (p<0.05). Significantly elevated levels of serum MDA were observed in T2DM cases with AMI than those without T2DM. Significance of the results has been discussed in terms of age at onset as well as severity of AMI. },

abstract = {Chronic obstructive pulmonary disease (COPD) is a heterogeneous collection of conditions characterized by irreversible expiratory airflow limitation. The disease is interspersed with exacerbations; periods of acute symptomatic, physiological, and functional deterioration. The present study was designed to investigate the role of X-ray cross-complementing group 1 (XRCC1) and apurinic/apyrimidinic endonuclease 1 (APE1) polymorphisms and the risk of COPD. Blood samples from 354 unrelated subject (age range 18–60 years; 156 with COPD, 198 healthy controls) were collected. Genomic DNA was isolated and genotyped for XRCC1 Arg399Gln and APE1 Asp148Glu using a confronting two pair primers polymerase chain reaction. GA genotype of XRCC1 gene was found to be predominant in the COPD group compared to controls with 1.86-fold increased risk for COPD (OR 1.86, 95 % CI 1.20–2.88, p = 0.0013). TG genotype of APE1 was found to be predominant in COPD group compared to controls with the difference being statistically significant (OR 1.68, 95 % CI 1.08–2.61, p = 0.0043). The GA haplotype was found to be predominant in COPD than controls with a 2.19-fold significant increase (OR 2.19, 95 % CI 1.46–3.28, p = 0.003). Polymorphism in XRCC1 and APE1 gene is associated with an increased risk of COPD.},

abstract = {Background: Women having gestational diabetes mellitus are at greater risk of effecting type 2 diabetes mellitus. Particularly because of the scarcity of data in India, there is requirement for understanding the distribution and possibility factors of dysglycaemia (types 2 diabetes mellitus and prediabetes) in women having affected earlier with gestational diabetes mellitus. Methods: All women (n = 751) with past history of GDM attending two obstetric units in Hyderabad were invited to participate in the study. Among them 279 (37.15%) accepted to take part in the present study. Socio-demographic, medical and anthropometric information were collected; and 75gm OGTT performed. Results: 213 (76.34%) women were found dysglycaemic within 5 year (median 14 months) of the pregnancy. Age was found to be 1.27 fold increase risk of having dys-

glycaemia (OR 1.27, 95% CI 1.03 - 1.35 p = 0.03). Presence of acanthosis nigricans (OR 2.09, 95% CI 1.89 - 6.56 p = 0.002), postpartum screening interval (OR 1.41, 95% CI 1.15 - 1.92 p = 0.02) were found to be risk factors to have dysglycaemia. The ADA suggested threshold HbA1c value of >39 mmol/mol (5.6%) have a sensitivity and specificity of 72.3% and 67.3% respectively for detecting the occurrence of T2DM postpartum. Conclusion: In conclusion, this study found a high possibility of development of t2dm among with a history of gdm and there is an immediate need to improve post-partum screening rates.},
