Different ploidy levels, diploid (2n=2x=24) to hexaploid (2n=6x=72) have been reported for Acorus calamus, a perennial medicinal plant. According to available information, there is a significant relationship between the ploidy level and essential oil compositions and medicinal properties of this important genetic resource. However, there is no information about the chromosome number of A. calam...

dear editor analysis of the phenylalanine hydroxylase (pah mckusick 261600) gene in different populations has revealed more than 320 different mutations associated with phenylketonuria (pku). one of these mutations, ivs10nt546, results in severe pah deficiency due to defective mrna splicing. it accounts for about 40 percent of all mutant alleles in turkish and between 10 to 20 percent of all mu...

BACKGROUND Despite increasing numbers of Iranian-American physicians practicing in the United States, little is known about the barriers that may impact them as providers of sexual health care. This is an important topic as discussions of sexual topics are generally considered a taboo among Iranians. We aimed to identify barriers experienced by Iranian-American physicians that inhibit their wil...

Chamomile serves as one of the most important medicinal plants. The most known secondary metabolites in chamomile species are volatile oils of triponoides, poly stilens, flavonoids and phenolic cafeic acid (Krori). These metabolites have wide variety of applications thanks to having medicinal properties of anti-inflammation, antispasmodic and bactericide activity. Also it is used to cure liver ...

Polymorphisms in the cytochrome P (CYP) 450 family may cause adverse drug responses in individuals. Cytochrome P450 2C19 (CYP2C19) is a member of the CYP family, where the presence of the 681 G>A, 636 G>A and 806 C>T polymorphisms result in the CYP2C19*2, CYP2C19*3 and CYP2C19*17 alleles, respectively. In the current study, the frequency of the CYP2C19*2, CYP2C19*3 and CYP2C19*17 alleles in an ...

Heck's disease or focal epithelial hyperplasia is a benign contagious disease caused by human papillomavirus types 13 or 32. It occurs with low frequency in the Iranian population. This condition is characterized by the occurrence of multiple, small papules or nodules in the oral cavity, especially on the labial and buccal mucosa and tongue. In some populations, up to 39% of children are affect...

X chromosome inactivation is widely studied using DNA sequence polymorphisms and DNA methylation as a surrogate measure of inactivation, but the correlation of methylation with inactivation is not perfect. Thus, it may be better to study sequence polymorphisms expressed in the mRNA. A recent paper reported use of a silent C/T polymorphism at nt 1311 of the G6PD cDNA, and this polymorphism was r...

In the present study, mitochondrial DNA polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) assay was used to assess the population structure and genetic relationships among six Persian sturgeon, Acipenser persicus populations from south Caspian Sea along the Iranian coast. The complete nucleotide dehydrogenase subunit 5 (NADH 5) region of mtDNA amplified by PCR was di...

the distribution of haptoglobin types of iranian living in bandaranbas (n=1246) is reported. hp1 gene frequencies reported in the literature for different populations in iran are given. comparison of the know hp1 distribution patterns show that the present hp1 frequency (0.266) is similar to other populations in iran.

PURPOSE Despite the importance of body satisfaction on self concept and well being, there is little study about it or its consequences in Iranian populations, a part of Asian culture. The aim of this study was the assessment of body satisfaction and body management strategies in Iranian university students. WORK METHOD This survey was performed based on a self-administrated questionnaire in 5...
