peppermint has considerable commercial value and widely cultivated for essential oil production, especially menthol. the aim of this study was to determine the quantitative expression of pulegone reductase (pr), menthofuran synthase (mfs) and limonene synthase (ls) genes in menthol biosynthesis pathway in mentha x piperita , using semiquantitative rt-pcr analysis and evaluating menthol producti...

mutations in any of four known nadph-oxidase components lead to cgd. x-linked cgd (x-cgd) is caused by defects in cybb, the gene that encodes gp91-phox. autosomal recessive (ar) cgd is caused by defects in the genes for p47 phox, p22-phox or p67-phox. the aim of this study was to screen the molecular defect in the fetus of an x-cgd carrier mother and postnatal confirmation of the results. in a ...

objective(s) nonviral vector can be an attractive alternative to gene delivery in experimental study. in spite of some advantages in comparison with the viral vectors, there are still some limitations for efficiency of gene delivery in nonviral vectors. to determine the effective expression, the recombinant escherichia coli lacz genes were cloned into the different variants of pcdna3.1 and then...

Premature Ovarian Failure (POF) defined as functional stop of ovaries before the age of 40. It is a common cause of infertility in women that characterized by primary or secondary amenorrhea, high gonadotropin levels and estrogen level declining in patients. Factors that reduce follicle or defect in the follicle growth stimulating mechanism defined as numerous complication factors that they can...

Background: Coronary artery disease (CAD) is a complex disorder. It thought to be result of gene-gene and gene-environment interactions. was reported that XbaI polymorphism ApoB gene associated with CAD. However, the results were conflicting risk factors not fully studied in previous studies. Aim: estimate association lipid profile, dietary pattern CAD Egyptian population. Subjects Methods: Thi...

Genome-wide association studies, in which as many as a million single nucleotide polymorphisms (SNP) are measured on several thousand samples, are quickly becoming a common type of study for identifying genetic factors associated with many phenotypes. There is a strong assumption that interactions between SNPs or genes and interactions between genes and environmental factors substantially contr...

introduction: x chromosome inactivation (xci) is a process during which one of the two x chromosomes in female human is silenced leading to equal gene expression with males who have only one x chromosome. here we have investigated xci ratio in females with opioid addiction to see whether xci skewness in women could be a risk factor for opioid addiction. methods: 30 adult females meeting dsm iv ...
