    High prevalence of premature coronary heart disease in Pakistanis compared to other populations points towards the genetic predisposition of this population to develop this disease. Since no investigations have been carried out in Pakistan to study the relationship of polymorphisms in genes involved in homocysteine cycle, the objective of the present study was to find out if there is any association of methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C; methionine synthase (MS) A2756G; cystathionine-beta-synthase (CBS) 844ins68, G919A polymorphisms with premature acute myocardial infarction (AMI) in a population of Pakistani patients with this disease. In a cross-sectional study, DNA samples of 143 AMI patients (age \u3c 45 years) and 153 healthy controls were genotyped for the above mentioned polymorphisms using PCR-RFLP methods. Plasma/serum samples of both patients and healthy controls were screened for homocysteine, folate and vitamin B12. One way ANOVA and chi-squared test were used for analysis of data. Mean plasma homocysteine levels in premature AMI patients and healthy controls were found to be 23±17.2 and 23±13.4 mumol/l, respectively which are higher than the upper normal limit of this biomarker (15mumol/l). MTHFR 677 CT genotype in healthy controls and MTHFR 677 TT genotype in AMI patients were found to have significantly increased levels of plasma homocysteine (p value \u3c 0.05), while all other polymorphisms did not show any significant difference in mean levels of homocysteine between AMI patients and healthy controls. Moreover, no association was observed between MTHFR C677T, A1298C; MS A2756C; CBS844ins68 polymorphisms and premature AMI in this population. This indicates that common polymorphisms in MTHFR, MS and CBS genes have no role in premature AMI in Pakistani population

    During this research morphological data was recorded 1st before starting labe.  Work. In free choice test, the response of both species of Callosobruchus on candidate variety for oviposition was different. The adult emergence of both species of Callosobruchus on candidate varieties shows no significant difference. Both species of Callosobruchus in free choice test have no significant difference for percent   adult’s emergence on candidate varieties. Percent damage of both species of Callosobruchus on candidate varieties was different. Keywords: Chickpea, Cicer arietinum L, Phytic acid, legumes, beetle, weevi

    Lack of association of methylenetetrahydrofolate reductase 677C\u3eT mutation with coronary artery disease in a Pakistani population

    Pakistanis belong to the South Asian population which has the highest known rate of coronary artery disease. Folic acid deficiency also appears to be highly prevalent in this population. Methylenetetrahydrofolate reductase (MTHFR) 677C\u3eT polymorphism decreases the activity of this enzyme and can be associated with mild to moderate hyperhomocysteinemia in homozygotes, particularly when there is folic acid deficiency, as well as with coronary artery disease. To assess the value of genotyping the MTHFR 677C\u3eT dimorphism, we carried out a case-control study of dimorphism 677C\u3eT for putative association with myocardial infarction (MI) among Pakistani nationals. We investigated a sample population of 622 Pakistanis consisting of 225 controls and 397 patients with clinical diagnosis of acute MI (AMI). MTHFR C677T alleles were determined by assays based on polymerase chain reaction and restriction endonuclease analysis. Frequencies of C alleles were 0.87 among controls and 0.86 among AMI patients. The MTHFR 677C\u3eT dimorphism showed no association with MI (chi(2) = 0.25, 1df, P=0.62), serum levels of folate and vitamin B12 and plasma level of vitamin B6. A significant association, however, was found between homozygous 677T genotype and plasma levels of homocysteine. Multivariate analysis of the data showed that in case of log homocysteine, age and MTHFR genotypes were significantly different (PT polymorphism, though associated with homocysteine levels, confers no significant risk of coronary artery disease in the Pakistani population investigated here. We suggest that the higher incidence of AMI in South Asia occurs through mechanisms other than the MTHFR related pathways

    Polymorphisms in MTHFR, MS and CBS Genes and Homocysteine Levels in a Pakistani Population

    Background: Hyperhomocysteinemia (\u3e15 mol/L) is highly prevalent in South Asian populations including Pakistan. In order to investigate the genetic determinants of this condition, we studied 6 polymorphisms in genes of 3 enzymes--methylenetetrahydrofolate reductase (MTHFR, C677T, A1298C), methionine synthase (MS, A2756G), cystathionine-beta-synthase (CBS, T833C/844ins68, G919A) involved in homocysteine metabolism and investigated their interactions with nutritional and environmental factors in a Pakistani population. Methodology/Principal Findings: In a cross-sectional survey, 872 healthy adults (355 males and 517 females, age 18-60 years) were recruited from a low-income urban population in Karachi. Fasting venous blood was obtained and assessed for plasma/serum homocysteine, folate, vitamin B12, pyridoxal phosphate and blood lead. DNA was isolated and genotyping was performed by PCR-RFLP (restriction-fragment-length-polymorphism) based assays. The average changes in homocysteine levels for MTHFR 677CT and TT genotypes were positive [beta(SE beta), 2.01(0.63) and 16.19(1.8) mol/L, respectively]. Contrary to MTHFR C677T polymorphism, the average changes in plasma homocysteine levels for MS 2756AG and GG variants were negative [beta(SE beta), -0.56(0.58) and -0.83(0.99) mol/L, respectively]. The average change occurring for CBS 844ins68 heterozygous genotype (ancestral/insertion) was -1.88(0.81) mol/L. The combined effect of MTHFR C677T, MS A2756G and CBS 844ins68 genotypes for plasma homocysteine levels was additive (p valu

    The study investigated the association between emotional intelligence and academic success among undergraduates of Kohat University of Science & Technology (KUST), Pakistan. A sample of 186 students who were enrolled during the semester Fall 2015 to Spring 2018 was selected through a random sampling technique. A cross-sectional, descriptive and correlational research methods were employed in this study. A standardized tool "Emotional Intelligence Scale" was employed for the collection of information from the undergraduates. Cumulative Grade Point Average (CGPA) of the students was considered as academic success. Data were collected through personal visits. Statistical tools i.e., simple percentage, mean, standard deviation, ANOVA, Pearson's product-moment correlation and multiple linear regression were employed to reach the desired research outcomes. The findings revealed that there was a strong positive relationship (r = 0.880) between emotional intelligence and academic success among undergraduate students. The multiple linear regression analysis showed that self-development (Beta = 0.296), emotional stability (Beta = 0.197), managing relations (Beta = 0.170), altruistic behaviour (Beta = 0.145), and commitment (Beta = 0.117) predict academic success of undergraduates positively. The findings suggest that the emotional intelligence of the undergraduate students may be further improved so that their academic performance may further be enhanced
