Abstract
OBJECTIVE Polycystic ovary syndrome (PCOS) is a complex disorder with diverse metabolic implications. Diagnosis typically relies on oligo-amenorrhoea (OA), hyperandrogenism (HA), and polycystic ovarian morphology (PCOM). However, the role of polymenorrhoea in PCOS remains understudied. Additionally, limited information exists regarding metabolic disturbances in women with partial PCOS phenotypes that do not meet diagnostic criteria. This extensive database aims to provide substantial evidence on the metabolic implications of polymenorrhoea and partial PCOS phenotypes. DESIGN Prospective observational study. PATIENTS AND MEASUREMENTS In this single-centre study, 6463 women with PCOS-like characteristics and 3142 age-matched healthy women were included. The study compared clinical (anthropometry, modified Ferriman Gallwey [mFG] score), hormonal (serum testosterone), and metabolic (plasma glucose, serum lipids, insulin) characteristics between women diagnosed with PCOS, those with partial PCOS phenotypes, and the healthy control group RESULTS: In all, 5174 women met Rotterdam criteria for PCOS diagnosis, while 737 were classified as Pre-PCOS, including HA (n = 538), OA (n = 121), or PCOM (n = 78). Common clinical features included oligomenorrhoea (75.5%), hirsutism (82.9%), obesity (27.2%), hypertension (1.6%), metabolic syndrome (19.6%), and diabetes mellitus (5.6%). Women diagnosed with PCOS, HA only, and OA only exhibited higher average body mass index, plasma glucose levels (both fasting and 2 h after the oral glucose tolerance test), and lipid fractions in comparison to those with PCOM and the healthy controls. However, indices of insulin resistance were similar among women with PCOS, HA, PCOM, and OA, albeit higher than in the healthy controls. The polymenorrhoea subgroup (5.9%) had lower BMI and serum testosterone, but similar mFG score, plasma glucose, insulin, and lipid levels as the oligomenorrhoea subgroup. CONCLUSION The metabolic disturbances observed in Pre-PCOS women highlight the need to reassess diagnostic criteria. Including the polymenorrhoea subcategory in PCOS criteria is recommended due to similar metabolic dysfunctions as the oligomenorrhoea group.

Evaluation of SOCS5 mRNA and its association with serum IL-12 levels and rs41379147 SNP in various subsets of allergic disorders: A case control study. Mol Immunol 2023; 162:102-110.

Abstract
BACKGROUND The SOCS proteins act as suppressors of cytokine signaling by impeding certain signaling pathways. SOCS5, a constituent of the SOCS family, has been associated with the management of allergic reactions, primarily by impeding the signaling of interleukin-4 (IL-4), which is known to have a cardinal function in accelerating the development of an allergic reaction. The key goal of our research was to explore the probable ramifications of the SOCS5 single nucleotide polymorphism (SNP) namely rs41379147 on the expression of SOCS5 mRNA and serum IL-12 levels, as well as to analyze the interaction between SOCS5 genotypes and various clinicopathological parameters in atopic diseases. METHODS The study involved the enrollment of 314 subjects comprising 154 atopic individuals and 160 healthy controls. PCR-RFLP was employed to conduct SNP analysis. Real-Time PCR was employed to quantify SOCS5 mRNA. The enzyme-linked immunosorbent assay (ELISA) technique was used for the quantification of interleukin-12 and total IgE levels in the serum while as chemiluminescence was used to determine Vitamin D levels. RESULTS The PCR-RFLP analysis indicated a lack of statistically significant variation in genotypic and allelic frequencies between the cases and controls (p > 0.05) for - 9147 C/T SNP either in total atopy (OR-0.70, 95% CI=0.43-1.12, p =0.15), and on subgroup stratifications of chronic urticaria (OR-0.81, 95 % CI = 0.42-1.59, p = 0.61), allergic rhinitis (OR-0.63, 95 % CI = 0.33-1.19, p = 0.16) and bronchial asthma (OR-0.66,95% CI = 0.29-1.4, p=0.32). There was reduced mRNA expression of SOCS5 in total atopic cases, allergic rhinitis, bronchial asthma and chronic urticaria in comparison to controls which advocates the fact that SOCS5 has a protective role in allergic disease development. Despite the reduced amounts of IL-12 in total atopic cases and different allergic disorders in comparison to controls, IL-12 showed significant positive correlation with SOCS5 mRNA expression (p < 0.05). CONCLUSION SOCS5 SNP rs41379147(C/T) does not pose any significant risk towards the development of any allergic disorder and has no impact on the expression of SOCS5 and IL-12. Our study has shown the reduced mRNA expression of SOCS5 among individuals diagnosed with chronic urticaria, allergic rhinitis and bronchial asthma and the expression of SOCS5 showed complete dependence on the cytokine milieu of IL12. The modulation of SOCS5 and IL-12 may represent potential curative targets for treating the menace of allergic diseases and present promising avenues for future investigation.

Abstract
Background Hyperprolactinemia is associated with obesity, dyslipidemia, insulin resistance, and low-grade inflammation which may promote endothelial dysfunction (EnD). Limited work has been done on EnD in prolactinomas and we, therefore, studied serum markers of inflammation and EnD in patients with prolactinomas before and after treatment with dopamine agonists. Methodology Fifty-six treatment naïve patients with prolactinomas and fifty-three (apparently healthy age and sex-matched) controls were enrolled in the study and subjected to clinical assessment and laboratory investigations including blood glucose, total cholesterol, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, urea, creatinine, uric acid, erythrocyte sedimentation rate (ESR), highly sensitive C-reactive protein (hsCRP) and markers of EnD i.e., intercellular adhesion molecule-1 (ICAM-1) and vascular cell adhesion molecule-1 (VCAM-1). Patients were treated with a dopamine agonist (cabergoline) and parameters (like ESR, hsCRP, ICAM-1, and VCAM-1) were measured at 12 weeks. Results The majority of the patients (84%) were female, more than half (52%) had metabolic syndrome and over a third (36%) were obese. Blood glucose fasting, HbA1c, lipid fractions, ESR, hsCRP, ICAM-1, and VCAM-1 were significantly higher in patients than in controls. Median ICAM-1 was 1331.95 ng/ml (IQR 803.43-1825.99) in patients vs 753.04 ng/ml (IQR 402.04-871.55) in controls, P < 0.001 and median VCAM-1in patients was 971.35 ng/ml (IQR 695.03-1285.23) as against 634.56 ng/ml (IQR 177.49-946.50) in controls, p0.001. Serum ICAM-1 and VCAM-1 correlated positively with hsCRP. On multivariate regression analysis, serum hsCRP was the only significant predictor of change in ICAM-1 and VCAM-1. Normalization of serum PRL with CAB resulted in a significant decrease in metabolic parameters, ESR, hsCRP, ICAM-1, and VCAM-1. Conclusion Hyperprolactinemia because of prolactinoma is associated with EnD secondary to systemic inflammation and metabolic abnormalities which improve after treatment with DA.

Abstract
BACKGROUND The suppressors of cytokine signaling (SOCS) are a class of negative regulators for several aspects of cytokine signaling that have been attributed to the pathophysiology of inflammatory disorders. Given the role of the SOCS3 gene in regulating Th2 cell proliferation, our study aimed to analyze two SOCS3 SNPs viz. rs8074003 and rs7222391, and their potential influence on IL-4 levels and SOCS3 mRNA expression besides analyzing the interaction of the SOCS3 genotypes with the various clinicopathological parameters. METHODS A total of 314 subjects including 154 atopic cases and 160 healthy controls were genotyped for SOCS3 polymorphisms by PCR-RFLP. SOCS3 mRNA was quantified by Real-Time PCR. The serum IL-4 and total IgE levels were determined by ELISA and Vitamin-D levels were quantified by chemiluminescence. RESULTS The CC genotype of rs8074003 was more frequent in atopic cases and posed a 3- fold risk of atopy (p = 0.001) whereas CG and GG genotypes were widespread in the controls (p = 0.1). For the other SNP rs7222391, there was no difference in genotypic and allelic distribution. The SOCS3 mRNA expression and serum IL-4 levels were substantially increased in the atopic cases with a significant positive correlation between them (p < 0.05). CONCLUSION SOCS3 SNP rs8074003 poses a convincing risk of atopic disease development. The SOCS3 expression and IL-4 levels were up-regulated in total atopy and in its different presentations. It seems plausible to target SOCS3 and IL-4 as a potential target for the diagnosis of atopy and for the development of reliable personalized therapeutic strategies to control atopic conditions.

Abstract
OBJECTIVE Evidence suggests that ETV6/RUNX1 translocation in pediatric acute lymphocytic leukemia shows geographical variation. Therefore, the present study aimed at unveiling the incidence of ETV6/RUNX1 fusion in pediatric acute lymphocytic leukemia cases of this region using fluorescent in-situ hybridization. Besides, we aimed to determine the incidence of MLL gene rearrangement and the pattern of chromosomal abnormalities in this study group. METHODS Samples from 57 acute lymphocytic leukemia cases of pediatric age group were subjected to fluorescent in-situ hybridization and conventional cytogenetic analysis using standard methods. RESULTS Conventional cytogenetic analysis revealed chromosomal abnormalities in 19.3% cases. The other major chromosomal abnormalities reported were monosomies in 10.5%, hypodiploidy in 7%, marker chromosomes in 3.5% and deletions in 3.5% cases. We found a 44,XX,-7,-18, r(5), i(17q) complex karyotype in one of the cases. Fluorescent in-situ hybridization analysis revealed ETV6/RUNX1 translocation to be present in 28.07% cases and MLL gene rearrangement in 3.5% cases. 12.5% of ETV6/RUNX1 fusion positive cases were found to have a loss of ETV6 allele. Besides, 8.8% cases were found to exhibit a signal pattern suggestive of RUNX1 amplification. ETV6 gene deletion and MLL gene amplification was detected in 3.5% cases each, of our study. CONCLUSIONS Frequency of ETV6/RUNX1 fusion oncogene was found to be higher in pediatric ALL cases of Kashmir region as compared to that reported from other parts of India. Besides, a case was found to have a karyotype viz 44,XX,-7,-18, r(5), i(17q) that has not been reported elsewhere in the childhood ALL.

Abstract
Deleted in colorectal carcinoma (DCC) A > G (rs714) is the most widely studied SNP of tumor suppressor DCC gene found to be associated with increased risk of various cancers. Therefore, the aim of present case control study was to investigate the role of DCC A > G (rs714) in gallbladder cancer (GBC) in Kashmir and to conduct a meta-analysis of DCC A > G (rs714) polymorphism to demonstrate the more accurate strength of these associations. Genotyping was done by PCR/RFLP and confirmed by sequencing in 100 GBC cases, and 150 controls. We also performed a comprehensive meta-analysis of 2223 subjects (1118 cases and 1105 controls) to evaluate the association between DCC A > G (rs714) polymorphisms and cancer. In present case control study DCC A > G (rs714) genotypes did not modulate the GBC cancer risk. Meta-analysis results showed that DCC A > G (rs714) is associated with increased overall cancer risk. DCC A > G (rs714) polymorphism conferred significant risk for cancer in dominant model but in recessive model P-value was at borderline. DCC A > G (rs714) genotype was associated with increased risk of cancer in Asians and Kashmiri population whereas no such association was observed in Europeans. The evidence in this meta-analysis supports a modest involvement of DCC A > G (rs714) tumoursupressor pathway genes in cancer susceptibility.

Abstract
AIMS The present research aimed to examine the use of magnetite nanoparticles (MNPs) in combination with phyto-beneficial rhizobacterium (PhBR) for improvement of applied N recovery (ANR) from urea fertilizer in rice grown under deficient and optimum watering conditions. METHODS AND RESULTS The Bacillus sp. MR-1/2 was positive for acetylene reduction, phosphate solubilization and ACC deaminase activity at temperature ranges 35-45°C. In a pot experiment, urea, MNPs and Bacillus sp. MR-1/2 were applied either alone or in combination to rice plants grown in pots under water deficit and optimal watering conditions. Combined application of urea, MNPs and Bacillus sp. MR-1/2 increased the plant N content and ANR by 27 and 65%, respectively, over their respective control values in rice grown under optimum watering conditions, whereas these increases were 27 and 41%, respectively, in rice grown under water deficit conditions. This treatment also increased the kernel weight and plant dry matter by 36 and 60%, respectively, over control (urea alone) values in rice grown under water deficit conditions, whereas these increases were 31 and 21·8%, respectively, in rice grown under optimum watering conditions. Values of malondialdehyde (MDA) contents, ascorbate peroxidase (APX), catalase and ethylene concentration were higher in control treatment under both the watering regimes. The application of Bacillus sp. MR-1/2 either alone or in combination with MNPs and urea reduced MDA contents, APX, catalase and ethylene production in the rice plants. CONCLUSION The combined application of MNPs+Bacillus sp. MR-1/2 reduced the N losses from applied urea, increased N uptake and ANR in rice, decreased MDA contents, APX and catalase activity and ethylene level in rice grown under deficit and optimum water conditions. SIGNIFICANCE AND IMPACT OF THE STUDY The application of MNPs together with Bacillus sp. MR-1/2 may help to increase ANR and rice productivity under water deficit conditions with low cost of production.

Abstract
AIMS Considering a surge in the incidence of Diabetes mellitus (DM) across all ethnic groups and lack of any representative data from the tribal communities of Jammu and Kashmir, the present study aimed to assess the prevalence of DM and prediabetes in them. METHODS Subjects were recruited from five districts of Kashmir valley using multistage cluster sampling by probability proportional to size (PPS) technique. Data collection included recording of socio-demographic, medical facts, assessment of anthropometric parameters and biochemical evaluation HbA1c and random blood glucose measurements as per the American Diabetes Association (ADA) criteria were used for diagnosis of DM. RESULTS A total of 6808 subjects were recruited in this study including 2872 (42%) men and 3936 (58%) women with mean age of 39.60 ± 20.19 years and 35.17 ± 16.70 years, respectively. Around 8.60% subjects were obese, 38.9% were found to be hypertensive, 73% had dyslipidemia and 3.75% had metabolic syndrome. About 1.26% (0.5% males and 0.9% females) had DM and 11.64% had prediabetes based on HbA1c cut offs. Increasing age, body mass index and family history portend significant risk factors while smoking and sedentary lifestyle increased the risk marginally. CONCLUSIONS Although the prevalence of DM among tribals of Kashmir valley is lower than general population, the higher prediabetes to DM ratio may indicate a future trend of increasing DM prevalence in this disadvantageous subpopulation.

Abstract
BACKGROUND: The association between thyroid dysfunction and postoperative mortality is contentious. Thyroid function is frequently depressed during and after cardiopulmonary bypass surgical procedures, and this may adversely affect myocardial performance and postop outcome.OBJECTIVES: To study i) the changes and clinical significance of serum thyroid hormones during cardiopulmonary bypass (CPB), and ii) the association between biochemically assessed peri-op thyroid function and 30-day mortality after CBPSTUDY DESIGN: Prospective Cohort StudySUBJECTS: 279 patients undergoing various cardiac surgeries under cardiopulmonary bypass.METHODS: All consenting patients undergoing open heart surgery in last five years at a tertiary care centre in North-India were studied. The thyroid hormone levels (Total T3, T4 and TSH) were measured before admission, and postoperatively on Day 1 & 7, and 3 months following surgery. The patients’ gender, age, weight, body mass index, heart disease details, previous cardiac surgeries, and cardiac surgery-related data such as pump time, aortic clamping time, hypothermia duration, postoperative hemodynamic status and postoperative use of inotropic drugs were recorded and analysed. Patients were classified as having biochemically overt or subclinical hyperthyroidism or hypothyroidism, normal thyroid function, or non-classifiable state based on preoperative thyroid-stimulating hormone and total T4 values. Outcome data were collected from hospital records. Biochemical thyroid dysfunction was not systematically treated. Outcomes measured were length of ICU stay, postoperative complications and 30-day mortality.RESULTS: There was significant changes in thyroid function in patients undergoing cardiopulmonary bypass surgery (Fig 1). All patients showed a decrease in T3, T4 and TSH after surgery. Post-op complications were observed in 137 patients (49%) most common being atrial fibrillation (34%) followed by acute kidney injury (23%), infections (18%), dyselectrolytemia (7%), bleeding (1.4%) and ARDS (1.4%). Of 263 patients followed, eventually 26 patients expired with a mortality rate of 8.89% (95% CI, 0.4 - 19.4). Perioperatively, there was a significant correlation between 30-day with type of surgery (r, 0.26), aortic clamp time (r, 0.45), CBP time (r, 0.48), number of inotropes used (r, 0.57), hours of mechanical ventilation (r, 0.4), ICU stay (r, 0.13) and post-op complications (r, 0.24), as well as with the reduction in the thyroid hormone levels; 17 (7%), 3 (20%) and 6 (46%) patients of those with pre-op TSH level of <6.5, >6.5 and >10.5 mIU/L expired (p <0.001).CONCLUSION: Pre-op thyroid dysfunction is associated with increased mortality in patients undergoing cardiac surgery with CBP. Excess mortality with elevated serum TSH levels suggests the importance of timely detection and intervention in individuals with thyroid dysfunction undergoing cardiac surgery.Table of Contents oTable 1.

Abstract
Glutathione-S-transferase T1 (GSTT1) and glutathione-S-transferase M1 (GSTM1) genes are associated with increase susceptibility to developing different types of cancers. The aim of present study was to investigate the role of genetic variants of GSTM1 and GSTT1 in gallbladder cancer (GBC) and cholelithiasis in Kashmir valley. Genotyping was done by multiplex polymerase chain reaction in 100 GBC, 100 cholelithiasis, and 150 controls adjusted by age and sex. We also performed a meta-analysis of published studies on GSTM1 and GSTT1 to evaluate the association between the GSTM1 and GSTT1 polymorphisms and GBC. Pooled odds ratio (OR) and 95% confidence interval (CI) were calculated using random- or fixed-effects model. In the present study, no association was observed between GSTM1 null and GSTT1 null genotypes and GBC and cholelithiasis. Meta-analysis results showed that GSTM1 null genotype was associated with GBC risk (P = 0.042). Subgroup analysis by ethnicity showed that GSTM1 null (P = 0.024) and GSTT1 null genotype (P = 0.037) were significantly associated with risk of GBC in Asians. This is the first study to investigate the role of genetic variants of GSTM1 and GSTT1 in GBC in Kashmir valley and cholelithiasis in the world.

Abstract
Objective Arrhythmogenic cardiomyopathy (ACM) is not an uncommon cause of cardiac morbidity in Kashmir valley. This study was designed to document various clinical features and to sequence exons 11 and 12 of plakophilin 2 (PKP2) gene in these patients. Methods ACM patients who attended cardiology outpatient department of our institute from January 2014 to April 2015 were included in the study. Their records were reviewed. Controls were randomly selected, who had no history or family history of cardiac illness and had a normal cardiac examination. A blood sample was also taken from both the groups for sequencing of exon 11 and 12 of PKP2 gene. ACM patients were followed up until July 2016. Results Eleven ACM patients and seven controls were included in the study. Most common mode of presentation was ventricular tachycardia (VT). Two patients had left ventricular (LV) systolic dysfunction. One patient had a splice site mutation in exon 12 of PKP2 gene and one patient died during follow-up. One of the controls had an intronic variation that has no pathogenic significance vis-à-vis ACM. Conclusion Our study describes various clinical parameters in ACM patients and a recessive plakophilin 2 mutation after a limited PKP2 gene sequencing.

Abstract
AIM The genetic variants of the factor V (G1691A), prothrombin (G20210A) and MTHFR (C677T) genes have been widely implicated as inherited risk factors for developing venous thrombosis. This study was undertaken to reveal the frequency of these mutations in Kashmiri patients with venous thromboembolism. METHODOLOGY A case-control study was designed with 250 VTE patients and 250 healthy controls. The mutations were analysed using ARMS-PCR and PCR-RFLP approach. RESULT The factor V Leiden G1691A mutation was found in 17/250 (6.8%) VTE patients and prothrombin G20210A mutation was found in 7/250 (2.8%) VTE patients while no mutation was found in any of the healthy controls. Both the mutations were found to be significantly associated with the increased risk of VTE (p = 0.0001 and 0.0150 respectively) while no association of VTE risk with MTHFR C677T polymorphism was found (p = 0.53). CONCLUSION The increased frequency of factor V Leiden G1691A and prothrombin G20210A mutation in VTE patients indicates a significant role of these mutations in the development of VTE in our population. We therefore suggest the routine screening of these two mutations as thrombophilic markers in Kashmiri patients with venous thromboembolism.

Abstract
BACKGROUND Parathyroidectomy has been traditionally performed through bilateral neck exploration (BNE). However, with the use of intraoperative parathyroid hormone (IOPTH) assay along with preoperative localization studies, focused parathyroidectomy can be performed with good surgical success rate, multiglandular disease can be predicted, and hence recurrence and surgical failure can be prevented. Furthermore, it predicts eucalcemia in the postoperative period. The aim of this study was to evaluate the usefulness of IOPTH assay in guiding adequate parathyroidectomy in patients of primary hyperparathyroidism. MATERIALS AND METHODS Between year 2015 and 2017, 45 patients of primary hyperparathyroidism underwent parathyroidectomy with IOPTH assay employed as an intraoperative tool to guide the surgical procedure. Blood samples were collected: (1) at preincision time, (2) preexcision of gland, (3) 5-min postexcision of gland, and (4) 10-min postexcision of gland. On the basis of the Irvin criterion, an intraoperative PTH drop >50% from the highest either preincision or preexcision level after parathyroid excision was considered a surgical success. Otherwise, BNE was performed and search for other parathyroid glands done. RESULTS Ten-min postexcision PTH levels dropped >50% in 34 (75.6%) patients. True positive among them were 31 (68.8%), true negative 8 (17.7%), false positive 3 (6.6%), and false negative 3 (6.6%). We performed focused exploration at the outset in 40 (88.9%) patients and bilateral exploration for five patients as guided by preoperative localizing studies. Hence, IOPTH was helpful in guiding further exploration in 8 (17.7%) patients and prevented further exploration in 32 (71.1%) patients and also was able to predict eucalcemia in 97.7% patients at 6 months. Thus, IOPTH was able to obviate or to ask for additional procedure in 88.8% of patients. However, in three (6.6%) patients, IOPTH would guide unnecessary exploration and in equally, that is, three (6.6%) patients may require reoperation for unidentified parathyroids. CONCLUSION IOPTH in adjunct with other localizing studies is very helpful for carrying out successful parathyroidectomy in uniglandular disease and predicting postoperative eucalcemia. However, more importantly, its role is valuable in equivocal imaging, in such cases, it prevents unnecessary exploration or helps in adequate parathyroidectomy.

Abstract
Microphthalmia is a developmental eye defect that is highly variable in severity and in its potential for systemic association. Despite the discovery of many disease genes in microphthalmia, at least 50% of patients remain undiagnosed genetically. Here, we describe a cohort of 147 patients (93 families) from our highly consanguineous population with various forms of microphthalmia (including the distinct entity of posterior microphthalmos) that were investigated using a next-generation sequencing multi-gene panel (i-panel) as well as whole exome sequencing and molecular karyotyping. A potentially causal mutation was identified in the majority of the cohort with microphthalmia (61%) and posterior microphthalmos (82%). The identified mutations (55 point mutations, 15 of which are novel) spanned 24 known disease genes, some of which have not or only very rarely been linked to microphthalmia (PAX6, SLC18A2, DSC3 and CNKSR1). Our study has also identified interesting candidate variants in 2 genes that have not been linked to human diseases (MYO10 and ZNF219), which we present here as novel candidates for microphthalmia. In addition to revealing novel phenotypic aspects of microphthalmia, this study expands its allelic and locus heterogeneity and highlights the need for expanded testing of patients with this condition.

Abstract
OBJECTIVE Growth retardation is common in children with extrahepatic portal vein obstruction (EHPVO) and growth hormone (GH) resistance may play a dominant role. The aim of this study was to ascertain growth parameters and growth-related hormones in children with EHPVO, comparing with controls and to study the response of shunt surgery on growth parameters. MATERIALS AND METHODS The auxological and growth-related hormone profile (GH; insulin-like growth factor binding protein-3 [IGFBP-3] and IGF-1) of thirty children with EHPVO were compared with controls. The effect of shunt surgery on growth parameters in 12 children was also studied. RESULTS The mean height standard deviation score (HSDS) of cases (-1.797 ± 1.146) was significantly lower than that of controls (-0.036 ± 0.796); the mean weight SDS of cases (-1.258 ± 0.743) was also lower than that of controls (-0.004 ± 0.533). The mean GH level of cases (5.00 ± 6.46 ng/ml) was significantly higher than that of controls (1.78 ± 2.04 ng/ml). The mean IGF-1 level of cases (100.25 ± 35.93 ng/ml) was significantly lower as compared to controls (233.53 ± 115.06 ng/ml) as was the mean IGFBP-3 level (2976.53 ± 1212.82 ng/ml in cases and 5183.28 ± 1531.28 ng/ml in controls). In 12 patients who underwent shunt surgery, growth parameters significantly improved. CONCLUSIONS Marked decrease in weight and height SDSs associated with GH resistance is seen in children with EHPVO, which improves with shunt surgery.

Abstract
Background: Coronary artery disease (CAD) is a major cause of death and disability in developed countries. Chronic stable angina is the initial manifestation of CAD in approximately 50% of the patients. Recent evidence suggests that vitamin D is crucial for cardiovascular health. The prevalence of vitamin D deficiency in our region is 83%. A low level of vitamin D is associated with chronic stable angina. Aim: This study was aimed at supporting or refuting this hypothesis in our population. Materials and Methods: The study was a prospective case-control study. We studied 100 cases of chronic stable angina and compared them with 100 matched controls. Vitamin D deficiency was defined as <20 ng/mL, vitamin D insufficiency as 20-30 ng/mL and normal vitamin D level as 31-150 ng/mL. Results: The prevalence of vitamin D deficiency among cases and controls was 75% and 10%, respectively. 75% of the cases were vitamin D-deficient (<20 ng/mL); 12% were vitamin D-insufficient (20-30 ng/mL), and 13% had normal vitamin D levels (31-150 ng/mL). None had a toxic level of vitamin D. Among the controls, 10% were vitamin D-deficient, 33% were vitamin D-insufficient, and 57% had normal vitamin D levels. The mean vitamin level among cases and controls was 15.53 ng/mL and 40.95 ng/mL, respectively, with the difference being statistically significant (P ≤ 0.0001). There was no statistically significant relation between the disease severities, i.e., on coronary angiography (CAG) with vitamin D level. Among the cases, we found that an increasing age was inversely related to vitamin D levels (P = 0.027). Conclusion: Our study indicates a correlation between vitamin D deficiency and chronic stable angina. Low levels may be an independent, potentially modifiable cardiovascular risk factor.

Abstract
Introduction: Migraine is a complex, recurrent headache disorder that is one of the most common complaints in neurology practice. The role of various genes in its pathogenesis is being studied. We did this study to see whether an association exists between ACE gene I/D polymorphism and migraine in our region. Materials and Methods: The study included 100 patients diagnosed with migraine and 121 healthy controls. The study subject were age and gender matched. The analysis was based on Polymerase Chain Reaction (PCR) and included following steps: DNA extraction from blood, PCR and Restriction Fragment Length Polymorphism (RFLP). Results: Out of 100 cases, 69 were females and 31 were males. Fifty-seven were having migraine without aura and 43 had migraine with aura. 45 of the cases had II polymorphism, 40 had ID polymorphism and 15 had DD polymorphism in ACE gene. Conclusion: We were not able to find a statistically significant association between ACE gene I/D polymorphism with migraine. The reason for difference in results between our study and other studies could be because of different ethnicity in study populations. So a continuous research is needed in this regard in order to find the genes and different polymorphism that increase the susceptibility of Kashmiri population to migraine.

Abstract
BACKGROUND The gene for the vascular endothelial growth factor (VEGF), which promotes angiogenesis and permeability, is polymorphic. The aim of the present study was to evaluate the relationship between +936C>T and +404C>G polymorphism of VEGF with risk of esophageal cancer in the Kashmiri population in India. MATERIALS AND METHODS 150 esophageal cancer patients and 150 unrelated healthy controls were genotyped for two VGEF SNPs (+405C/G, and +936C/T) using DNA extracted from prospectively collected blood samples by the PCR-RFLP method. RESULTS For the VEGF +936C>T polymorphism a significant association of CT and combined CT+TT genotypes was observed with increased risk of esophageal cancer (p=0.021; 0.024). For the +405C>G polymorphism we observed significantly increased frequency of GG genotype in cases as compared to controls and also the +405 GG Genotype was observed to have a two fold risk(OR=2.7356; 95%CI=1.1409- 6.5593; p=0.020). The combined genotypes of GG-CC and GG-CT of +405C>G and +936C>T were found to be significantly associated with increased risk of esophageal cancer (p=0.0376; 0.0099). CONCLUSIONS From the results of the present study a significant association of +936C>T and +405C>G polymorphisms with increased esophageal cancer risk exists in the Kashmiri population.

Abstract
BACKGROUND The pathogenesis of chronic spontaneous urticaria involves interplay between the genetic and environmental factors, most of which is still poorly understood. It is well-recognized that 30-40% of chronic spontaneous urticaria is autoimmune in nature. Chronic autoimmune urticaria is caused by anti-FcɛR1β and less frequently, by anti-IgE auto antibodies that lead to mast cell and basophil activation, thereby giving rise to the release of histamine and other proinflammatory mediators. We investigated the association between SNP loci in FcɛR1β and chronic spontaneous urticaria and to see its relation with serum IgE levels in Kashmiri population. METHODS The autologous serum skin test was used as a screening test for chronic autoimmune urticaria. PCR-RFLP was used to detect the genotype of the SNP loci. Serum IgE levels were assessed by ELISA kit. RESULTS No significant difference was found between the study population and control group in genotype distribution (wild and variant) among FcɛR1β loci (P value=0.06, odds ratio=0.29). The frequency of FcɛR1β (C109T) in autologous serum skin test positive chronic autoimmune urticaria patients with the CT genotype was found to be statistically non-significant when compared with the wild genotype (P=0.35). Carriers of FcɛR1β (T allele) had a more significant risk of developing CAU than those with C allele (P=0.01). In our population serum total IgE levels did not find any statistical significance with regard to ASST positive & ASST negative patients (P=0.26). CONCLUSIONS There is statistically no significant association between FcɛR1β gene polymorphism and CSU in Kashmiri population; however, there is a probability of developing CSU in patients carrying FcɛR1β T allele. Furthermore, serum total IgE levels had no significant association with the development of CAU.

Abstract
BACKGROUND Chronic inflammation is considered as an important factor in the pathogenesis of lung cancer. The presence of inflammatory cells and higher levels of pro-inflammatory cytokines in the tumor microenvironment and their surrounding tissues is gaining much importance in research. MATERIALS AND METHODS One hundred ninety NSCLC cases and 200 age, smoking and sex matched controls were evaluated for association of IL-8 -251 (rs4073) and IL-8 -845 (rs2227532) in our population. Restriction fragment length polymorphism (RFLP) was used followed by direct sequencing for the detection of SNPs. RESULTS The IL-8 -845 polymorphism was not found in our population. No significant association was observed between the IL-8 -251 AT genotypes and IL-8 -25 AA genotypes and NSCLC (p=0.05) in our population. The IL-8 -251 A allele was also non-significant (p=0.05) in NSCLC patients. CONCLUSIONS In conclusion, this report reveals lack of association between IL-8 - 251 A/T polymorphism and NSCLC in our Kashmir Valley population.

Abstract
Introduction Interleukin 1 beta (IL- 1β), a key proinflammatory cytokine encoded by the interleukin 1 beta gene, has been associated with chronic inflammation and plays an important role in lung inflammatory diseases including lung cancer. Elevated levels of Interleukin 1proteins, in particular interleukin 1 beta greatly enhance the intensity of the inflammatory response. Aim To study the role of interleukin 1 beta-31C > T and -511 T > C polymorphism in the pathogenesis of non small cell lung cancer (NSCLC). Materials and methods One hundred and ninety non small cell lung cancer patients and 200 healthy age, sex, smoking and dwelling matched controls were used for polymorphic analysis by polymerase chain reaction—restriction fragment length polymorphism (PCR-RFLP) followed by sequencing. Normal tissues of 48 histopathologically confirmed non small cell lung cancer patients were taken for mRNA expression analysis. Quantitation of interleukin 1 beta was carried out by quantitative real time PCR. Result The T/T genotype of interleukin 1 beta-31 gene was significantly associated with increased risk of NSCLC [(P = 0.001, OR – 2.8 (95%CI 1.52–5.26)]. The interleukin 1 beta − 511 T > C does not show any difference between the NSCLC and control group (P = 0.3, OR – 0.72 (95%CI 0.41–1.28). Quantitative analysis of mRNA showed significant association with interleukin 1 beta T allele as compared to the interleukin 1 beta-31C allele (P = 0.006). Conclusion We conclude that lung cancer risk genotype interleukin 1 beta-31TT results in increased expression of interleukin 1 beta mRNA in lung cancer patients. Our data suggest that this genotype (IL1β -31TT) in the interleukin 1 beta regulatory region provide a microenvironment with elevated inflammatory stimuli and thus increasing the risk for lung cancer.

Abstract
BACKGROUND The glutathione S transferase (GST) family of enzymes plays a vital role in the phase II biotransformation of environmental carcinogens, pollutants, drugs and other xenobiotics. GSTs are polymorphic and polymorphisms in GST genes have been associated with cancer susceptibility and prognosis. GSTP1 is associated with risk of various cancers including bladder cancer. A case control study was conducted to determine the genotype distribution of GSTP1 A>G SNP, to elucidate the possible role of this SNP as a risk factor in urinary bladder cancer (UBC) development and to examine its correlation with clinico-pathologic variables inUBC cases. MATERIALS AND METHODS Using the polymerase chain reaction-restriction fragment length polymorphism (PCR- RFLP) approach, we tested the genotype distribution of 180 bladder cancer patients in comparison with 210 cancer-free controls from the same geographical region with matched frequency in age and gender. RESULTS We did not observe significant genotype differences between the control and bladder cancer patients overall with an odds ratio (OR)=1.23 (p>0.05). The rare allele (AG+GG) was found to be present more in cases (28.3%) than in controls (24%), though the association was not significant (p<0.05). However, a significant risk of more than 2-fold was found for the variant allele (AG+GG) with smokers in cases as compared to controls (p>0.05). CONCLUSIONS Thus, it is evident from our study that GSTP1 SNP is not implicated overall in bladder cancer, but that the rare, valine-related allele is connected with higher susceptibility to bladder cancer in smokers and also males.

Abstract
BACKGROUND Vitamin D regulates many biological processes including bone metabolism, innate immune response, and cell proliferation and differentiation by binding to its receptor VDR. Vitamin D receptor (VDR) gene polymorphisms have been associated with many cancers like breast, colorectal, prostate, and skin. The main aim of this study was to determine whether VDR polymorphisms (ApaI, BsmI and FokI) are associated with increased risk of multiple myeloma. METHODS We designed a case control study where 75 multiple myeloma cases were studied for VDR polymorphisms (ApaI, BsmI and FokI) against 150 controls taken from general population. The polymorphisms of VDR gene were investigated using PCR-RFLP method. RESULTS We did not find any significant association between ApaI and BsmI polymorphisms and multiple myeloma risk (P>0.05), but FokI polymorphism was significantly associated with increased risk for multiple myeloma. We also found a significant association between the ff variant genotype with creatinine levels, albumin levels, and Durie-Salmon stage III. CONCLUSION Our findings suggest that the FokI polymorphism is involved in the increased susceptibility to development and progression in multiple myeloma in the ethnic Kashmiri population. Furthermore these results suggest that ff genotype is associated with higher risk for developing multiple myeloma.

Abstract
Glutathione-S-transferase P1 (GSTP1) is a critical enzyme of the phase II detoxification pathway. One of the common functional polymorphisms of GSTP1 is A→G at nucleotide 313, which results in an amino acid substitution (Ile105Val) at the substrate binding site of GSTP1 and reduces catalytic activity of GSTP1. To investigate the GSTP1 Ile105Val genotype frequency in prostate cancer cases in the Kashmiri population, we designed a case-control study, in which 50 prostate cancer cases and 45 benign prostate hyperplasia cases were studied for GSTP1 Ile105Val polymorphism, compared to 80 controls taken from the general population, employing the PCR-RFLP technique. We found the frequency of the three different genotypes of GSTP1 Ile105Val in our ethnic Kashmir population, i.e., Ile/Ile, Ile/Val and Val/Val, to be 52.4, 33.3 and 14.3% among prostate cancer cases, 48.5, 37.5 and 14% among benign prostate hyperplasia cases and 73.8, 21.3 and 5% in the control population, respectively. There was a significant association between the GSTP1 Ile/Val genotype and the advanced age group among the cases. We conclude that GSTP1 Ile/Val polymorphism is involved in the risk of prostate cancer development in our population.

Abstract
Methylenetetrahydrofolate reductase (MTHFR) is a critical enzyme in folate metabolism and is involved in DNA synthesis, DNA repair and DNA methylation. The two common functional polymorphisms of MTHFR, 677 C→T and 1298 A→C, have been shown to impact various diseases, including cancer. The 677 C→T polymorphism has been widely investigated in different cancers and has been implicated as a risk factor for the development of various cancers. We investigated MTHFR C677T genotype frequency in colorectal cancer cases in the Kashmiri population and correlated this information with the known clinicopathological characters of colorectal cancer, in a case-control study. Eighty-six colorectal cancer cases were studied for MTHFR C677T polymorphism, compared to 160 controls taken from the general population, employing the PCR-RFLP technique. We found the frequency of the three different genotypes of MTHFR in our ethnic Kashmir population, i.e., CC, CT and TT, to be 68.6, 20.9 and 10.4% among colorectal cancer cases and 75.6, 16.9 and 7.5% among the general control population, respectively. There was a significant association between the MTHFR TT genotype and colorectal cancer in the higher age group. We conclude that the MTHFR C677T polymorphism slightly increases the risk for colorectal cancer development in our ethnic Kashmir population.

Abstract
Ginkgo biloba extract, EGb 761, a popular and standardized natural extract, contains 24% ginkgo-flavonol glycosides and 6% terpene lactones. EGb 761 is used worldwide to treat many ailments, and although a number of studies have shown its neuroprotective properties, the mechanisms of action have not been elucidated fully. We hypothesize that EGb 761 and some of its bioactive components [Bilobalide (BB), Ginkgolide A (GA), Ginkgolide B (GB), and Terpene Free Material (TFM)] could provide neuroprotection in ischemic conditions through heme oxygenase 1 (HO1). Mice were subjected to permanent distal middle cerebral artery occlusion (pMCAO) and survived for 7 days. HO1 knockout (HO1⁻/⁻) mice showed significantly higher (P<0.05) infarct volume and Neurologic Deficit Scores (NDS) as compared to their wildtype (WT) counterparts. In another cohort, WT mice subjected to pMCAO and treated at 4 h of pMCAO with 100 mg/kg EGb 761, 6 mg/kg BB, GA, GB, or 10 mg/kg TFM showed significantly lower (P<0.05) infarct volumes (BB; 29.0±3.9%, GA; 31.3±4.0%, GB; 32.0±3.8%, TFM; 32.5±3.5%, and EGb 761; 27.4±4.5%) than those in the vehicle-treated mice (46.0±3.7%). Similarly, NDS were lower in BB; 7.1±1.8, GA; 7.4±2.1, GB; 7.9±1.8, TFM; 7.7±1.7, and EGb 761; 6.8±2.0 groups as compared with the vehicle-treated group (13.8±1.5). Interestingly, the protective effect of EGb 761 was essentially lost when HO1 knockout mice were treated with EGb 761. In another cohort, HO1, vascular endothelial growth factor (VEGF) and endothelial nitric oxide synthase (eNOS) protein levels in the brain cortices appeared to be higher in EGb 761 and BB but not in GA, GB and TFM treated groups. Together, these results suggest that HO1 plays, at least in part, an important role in the neuroprotective mechanism of EGb 761 and in delayed ischemia. Targeting this pathway could lead to neuroprotective agents against ischemic stroke.

Abstract
We and others have identified that inhibition of cyclooxygenase might not be the optimal approach to limiting brain damage after stroke. Now we are investigating the unique properties of the various prostaglandin receptors to determine whether blocking those that mediate toxicity or stimulating those that reduce toxicity will improve neurological outcomes. Here, we determined the respective contribution of the prostaglandin I(2) (PGI(2)) receptor in transient middle cerebral artery (MCA) occlusion (tMCAO) and permanent MCAO (pMCAO) preclinical stroke models by using male wildtype (WT) and IP receptor knockout (IP(-/-)) C57Bl/6 mice. In addition, we investigated the putative preventive and therapeutic effects of the IP receptor agonist beraprost. The infarct volumes and neurological deficit scores (NDS) were significantly greater in IP(-/-) than in WT mice after both tMCAO and pMCAO. Interestingly, beraprost pretreatment (50 or 100 microg/kg p.o.) 30 min before tMCAO and post-treatment (100 microg/kg p.o.) at 2 or 4.5 h of reperfusion significantly reduced the neurological deficit score and infarct volume in WT mice. Post-treatment with beraprost (100 microg/kg p.o.) 4.5 h after pMCAO also significantly decreased neurological deficits and infarct volume in WT mice. Together, these novel findings suggest for the first time that PGI(2) IP receptor activation can attenuate anatomical and functional damage following ischemic stroke.

Abstract
Background: Corticosteroid insufficiency in acute illness can be difficult to discern clinically. Occult adrenal insufficiency (i.e., Δmax ≤9 μg/dL) after corticotropin may be associated with a high mortality rate. Objective: To assess the prevalence of occult adrenal insufficiency and the prognostic value of short corticotropin stimulation test in patients with septic shock. Materials and Methods: A total of 30 consecutive patients admitted in the adult intensive care unit of the Sheri Kashmir Institute of Medical Sciences who met the clinical criteria for septic shock were prospectively enrolled in the study. A low dose (1 μg) short corticotropin stimulation test was performed; blood samples were taken before the injection (T0) and 30 (T30) and 60 (T60) minutes afterward. Results: The prevalence of occult adrenal insufficiency was 57%. The 28-day mortality rate was 60% and the median time to death was 12 days. The following seven variables remained independently associated with death: organ system failure scores, simplified acute physiology score II score, mean arterial pressure, low platelet count, PaO2:FIO2, random baseline cortisol (T0) >34 μg/dL, and maximum variation after test (Δmax) of ≤9 μg/dL. Three different mortality patterns were observed: (I) low (T0 ≤34 μg/dL and Δmax >9 μg/dL; a 28-day mortality rate of 33%),(II) intermediate (T0 >34 μg/dL and Δmax >9 μg/dL or T0 ≤34 μg/dL and Δmax ≤9 μg/dL; a 28-day mortality rate of 71%), and (III) high (T0 >34 μg/dL and Δmax ≤9 μg/dL; a 28-day mortality rate of 82%). Conclusion: A short corticotropin test using low-dose corticotropin (1 μg) has a good prognostic value. High basal cortisol and a low increase in cortisol on corticotropin stimulation test are predictors of a poor outcome in patients with septic shock.

Abstract
Two TP53 gene polymorphisms at codon 47 (TP53 Pro47Ser) and at codon 72 (TP53 Arg72Pro) have been associated with susceptibility to various cancers. We carried out a case-control study and examined the genotype distribution of TP53 Pro47Ser and Arg72Pro single nucleotide polymorphisms (SNPs), using a PCR-RFLP approach, to determine if these two SNPs are risk factors for colorectal cancer (CRC) development and to look for a possible correlation of these two SNPs with clinicopathological variables of CRC. We investigated the genotype distribution of these SNPs in 86 CRC cases in comparison with 160 healthy subjects in an ethnic Kashmiri population. TP53 Arg72Pro SNP genotype frequencies differed significantly (P = 0.000001) between the groups; the frequency of the Pro/Pro mutant was almost 20% in the general population. We also found significant association of the Pro/Pro mutant with tumor location, nodal status/higher tumor grade and bleeding per rectum/constipation. We conclude that Arg72Pro SNP is associated with susceptibility to developing CRC in this ethnic Kashmiri population.

Abstract
Prostaglandin D(2) (PGD(2)) is the most abundant prostaglandin produced in the brain. It is a metabolite of arachidonic acid and synthesized by prostaglandin D(2) synthases (PGDS) via the cyclooxygenase pathway. Two distinct types of PGDS have been identified: hematopoietic prostaglandin D synthase (H-PGDS) and lipocalin-type prostaglandin D synthase (L-PGDS). Because relatively little is known about the role of L-PGDS in the CNS, here we examined the outcomes in L-PGDS knockout and wild-type (WT) mice after two different cerebral ischemia models, transient middle cerebral artery (MCA) occlusion (tMCAO) and permanent distal middle cerebral artery occlusion (pMCAO). In the tMCAO model, the MCA was occluded with a monofilament for 90 min and then reperfused for 4 days. In the pMCAO model, the distal part of the MCA was permanently occluded and the mice were sacrificed after 7 days. Percent corrected infarct volume and neurological score were determined after 4 and 7 days, respectively. L-PGDS knockout mice had significantly greater infarct volume and brain edema than did WT mice after tMCAO (P<0.01). Similarly, L-PGDS knockout mice showed greater infarct volume and neurological deficits as compared to their WT counterparts after pMCAO (P<0.01). Using the two models enabled us to study the role of L-PGDS in both early (tMCAO) and delayed (pMCAO) ischemic processes. Our findings suggest that L-PGDS is beneficial for protecting the brain against transient and permanent cerebral ischemia. These results provide a better understanding of the role played by the enzymes that control eicosanoid synthesis and how they can be utilized as potential targets to prevent damage following either acute or potentially chronic neurological disorders.

Abstract
BACKGROUND The worldwide prevalence of vitamin D deficiency is reported to be high. OBJECTIVES To assess the vitamin D status in apparently healthy adults in Kashmir valley by measuring serum 25-hydroxyvitamin D (25 (OH) D). METHODS 92 healthy natives (64 men and 28 non-pregnant/non-lactating women, aged 18-40 years), residing in Kashmir for at least last 5 years and not having any suggestion of systemic disease, were selected for this study. The samples were collected throughout the year in both summer and winter months. Vitamin D deficiency was defined as a serum 25 (OH) D concentration of <50 nmol/l and graded as mild (25-50 nmol/l), moderate (12.5-25 nmol/l) and severe (<12.5 nmol/l). RESULTS Body mass index, total energy intake, and other nutritional parameters were comparable among subjects in different groups. Overall 76 (83%) of the subjects studied had vitamin D deficiency--25%, 33%, and 25% had mild, moderate, and severe deficiency, respectively. 49 of the 64 males and all but 1 of the 28 females were vitamin D deficient. The prevalence of vitamin D deficiency ranged from 69.6% in the employed group to 100% in the household group. Vitamin D deficiency was equally prevalent in subjects from rural and urban areas. Serum calcium and phosphorus values were comparable in subjects with and without vitamin D deficiency, while daily intake and urinary excretion of calcium were significantly lower in the former. Vitamin D deficient subjects had a significantly lower mean weekly exposure to sunlight. CONCLUSIONS In spite of abundant sunlight, healthy individuals in Kashmir valley are vitamin D deficient, particularly women. Serum 25 (OH) D concentrations are significantly related to sun exposure.
