  Obesity has become a global public health problem. It occurs due to a positive energy balance leading to adipose tissue expansion. White adipose tissue was an endocrine organ which secreted resistin. Resistin also produced by immune cells due to low chronic level inflammation might cause higher resistin level in obese people. Polymorphism +62G>A RETN gene was reported has a relationship with low resistin level and A allele as a protective allele. This study aimed to determine genotype and allele frequency distribution concerning resistin level. Another objective aimed to know the correlation between resistin level with body mass index. The design of the research was a case-control study with 122 people (18-40 y.o.), divided equally in the case group (BMI ≥ 27 kg/m2) and control group (BMI 18.5-24.9 kg/m2) without diabetes mellitus. Blood was taken after fasting a minimal 8 hours. Plasma was used to measure the resistin level. DNA genotyping was analyzed using PCR-RFLP. Genotyping result showed three genotypes of RETN gene +62G>A polymorphism (GG, GA, AA). There was no significant difference in genotype and allele frequency distribution related to obesity status (p=0.680; p=1) and resistin level (p=0.537) between case and control group. There was no significant difference in resistin level between case and control group (p=0.770). Resistin level was correlated with BMI in obese group (p= 0.05; r= -0.25). The present study concludes that there is no significant difference in genotype and allele frequency distribution related to obesity status and resistin level. Resistin level has a negative correlation with BMI.

BackgroundA previous study showed an association between owner-reported exposure to environmental tobacco smoke (ETS) and lymphoma in cats. This study aimed to investigate the association between ETS exposure and gastrointestinal lymphoma in cats, using hair nicotine concentration (HNC) as a biomarker.MethodsThis was a prospective, multi-centre, case–control study. Gastrointestinal lymphoma was diagnosed on cytology or histopathology. Hair samples were obtained from 35 cats with gastrointestinal lymphoma and 32 controls. Nicotine was extracted from hair by sonification in methanol followed by hydrophilic interaction chromatography with mass spectrometry. Non-parametric tests were used.ResultsThe median HNC of the gastrointestinal lymphoma and control groups was not significantly different (0.030 ng/mg and 0.029 ng/mg, respectively, p=0.46). When the HNC of all 67 cats was rank ordered and divided into quartiles, there was no significant difference in the proportion of lymphoma cases or controls within these groups (p=0.63). The percentage of cats with an HNC≥0.1 ng/mg was higher for the lymphoma group (22.9%) than the control group (15.6%) but failed to reach significance (p=0.45).ConclusionA significant association was not identified between HNC (a biomarker for ETS) and gastrointestinal lymphoma in cats; however, an association may exist and further studies are therefore required.

Abstract Objective: This study aimed to investigate the association between p73 C14T (rs1801173) polymorphism and the risk of GC in a Chinese Han population. Methods: A hospital-based case-control study was conducted. A total of 577 GC cases and 678 normal controls were recruited. Their genotypes were determined using the SnapShot method. Results: The genotype frequency distribution of the case group and the control group were consistent with the Hardy–Weinberg equilibrium. No significant difference was found in the distribution of gender, age, and drinking history between the case group and the control group. A correlation was observed between smoking and the incidence of GC (P = 0.006). Three genotypes of CC, CT, and TT were found in the rs1801173 locus of p73. The distribution of the dominant model/recessive model did not significantly differ (P = 0.688; 0.937). No statistical difference was found even after adjustment was performed via logistic regression analysis (P = 0.703; 0.990). The frequency distribution between the two groups also did not significantly differ (P = 0.763). Conclusion: Smoking is related to the occurrence and development of GC. No association was found between p73 rs1801173 C > T SNP and the risk of GC in a Chinese Han population. However, additional larger studies and tissue-specific biological characterization are required to confirm these findings.

ObjectiveThe purpose of the study was to examine whether the insertion (I) and/or deletion (D) polymorphism of ACE confers susceptibility to primary pterygium in Sardinian patients in a case–control study.Methods and resultsPolymorphism genotyping was performed by nested PCR using genomic DNA extracted from the whole peripheral blood of participants with (n=251) and without (n=260) pterygium. DD, ID and II genotype frequencies were: 48%, 39% and 13%, respectively, for patients with pterygium, and 15%, 40% and 44%, respectively, for the control group. A statistically significant difference was found between the pterygium and control groups for the ACE I/D polymorphism (p<0.001). Moreover, a statistically significant difference was found between the DD and II groups (p<0.01; OR=10.49; 95% CI 6.18 to 17.79), DD+ID versus II group (p<0.01; OR=5.23; 95% CI 3.37 to 8.13) and DD versus ID groups (p<0.01; OR=3.21; 95% CI 2.04 to 5.04).ConclusionsStatistical analysis showed that the DD genotype is associated with an increased risk of developing pterygium, and with a good chance that the D allele may play an important role in the development of disease.

Abstract BackgroundRecent evidences suggested that deficiency of Vit-D is associated with risk of ischemic stroke and its severity. The mechanism behind its relationship have been linked to total oxidant level and some other modifiable risk factor like hypertension, diabetes, smoking and alcohol consumption and tobacco chewing. However, there are disappearances in evidences. The aim of this study is to find out the role of Vit-D and Total oxidants in ischemic stroke and in disease progression.MethodsIn this case control study total 205 individuals of case and control enrolled in this study the demographic data like age, gender, ethnicity, dietary habit, addiction (smoking, alcohol, tobacco chewing) previous history of disease (hypertension, diabetes, any cardiovascular disease) were collected from family members and other medical record. ResultsThe mean age of case and control group of 63.91 ± 12.66 and 62.52 ± 7.04 respectively. There was significant difference between insufficient Vit-D level in case and control group (p<0.05) however, there were significant difference of MDA in the groups classified on the basis of Vit-D level in case and control (p<0.05) moreover, there were inverse association observed between Vit-D and MDA level in both case and control. Vit-D and MDA shows significant association ischemic stroke however, MDA have association with stroke severity. ConclusionThe result shows higher prevalence of Vit-D deficiency in ischemic stroke patients which induce MDA level parallelly. At low level of Vit-D and high level of MDA associated with the severity of stroke. Moreover, Vit-D and MDA shows significant association with stroke occurrence. Furthermore, MDA significantly associated with stroke severity however Vit-D does not show any association with stroke severity

Abstract Back groundThe precise etiology of infantile colic has not been elucidated after many years of research. In this study, we aimed to determine the association of fecal calprotectin with infantile colic.MethodThis case control study was performed on colicky infants referred to pediatrics clinics in Zanjan over a 6-month period. Infantile colic was clinically defined based on wessel criteria. The control group consisted of healthy infants matched for age, sex, weight, and type of feeding with the case group. Fecal calprotectin levels were measured in both groups by the ELISA method.ResultsForty infants were divided equally into case and control groups. The cases consisted of 11 boys (55%) and 9 girls (45%) with a mean age of 63 days and in the control group there was 12 boys (60%) and 8 girls (40%) with mean age of 48 days. Fecal calprotectin was positive in 17 (85%) cases and 6 (30%) controls. This difference was statistically significant. There was no significant difference in fecal calprotectin regarding sex, age, weight and type of nutrition in both colicky infants and controlsConclusionFecal calprotectin levels in colicky infants were significantly higher than healthy infants.

Abstract Objectives Apolipoprotein AIV has a role in chylomicrons and lipid secretion and catabolism. Also, Apo-AIV plays a role in the regulation of appetite and satiety. Previous studies on rats have shown that hyperthyroidism and hypothyroidism are associated with significant changes in Apo-AIV serum levels. There has been no research on serum Apo-AIV changes in hyper and hypothyroidism in humans. Methods This case-control study was performed on new patients with hyper and hypothyroidism. Eighteen patients with hyperthyroidism and 18 patients with hypothyroidism enrolled in the study. After 12 weeks treatment blood samples were recruited. If euthyroidism was achieved, serum Apo-AIV level was measured. Eighteen euthyroid healthy individuals without thyroid disease were chosen as the control group from general population. Results Serum levels of Apo-AIV before treatment in hypothyroidism, hyperthyroidism and in the control group were 85.61, 110.66 and 33.51 mg/dL respectively (p<0.001), which was significantly higher in hyperthyroid patients than hypothyroidism and control group. In patients with hyperthyroidism there was a significant decrease in serum levels of Apo-AIV after treatment (p=0.044). However in hypothyroidism a non-significant elevation in serum levels of Apo-AIV was observed (p=0.403). Furthermore, serum levels of Apo-AIV after treatment were significantly higher in both hyperthyroidism and hypothyroidism in comparison to control group (p<0.001). Conclusions The results of this study for the first time showed that the serum level of Apo-AIV is increased in patients with hyperthyroidism and is decreased in patients with hypothyroidism, and after treatment, there was a significant difference with the control group.
