syrian rue or harmal ( peganum harmala l.), belonged to the family of peganaceae, grows in semi-arid climates such as the middle east and north africa. traditionally, this plant, especially the seeds, has been recognized for its several medicinal uses. in this stydy, genetic diversity between 21 harmal accessions, collected from different regions of iran were evaluated by inter simple sequence ...

meiotic study was performed in 11 brassica napus cultivars considering chiasma frequency anddistribution, chromosome pairing, as well as the occurrence of b-chromosomes and their effects on chiasmafrequency. such cytogenetic pairing, along with agronomic characteristics, may be used in planninghybridization among the b. napus cultivars. all the cultivars studied possessed n=19 chromosome number...

introduction crimean-congo hemorrhagic fever (cchf) is a viral hemorrhagic fever which transmitted by tick-bites, or through contact with infected animal tissues or secretions during and immediately post-slaughter. it can be responsible for severe outbreaks in humans. case presentation we have explained five patients of a family with (cchf), which acquired the illness at one time. every five pa...

in this study, we considered some competitive learning methods which include hard competitive learning (hcl) and soft competitive learning (scl) with/ without fixed network dimensionality for reliability analysis in microarrays. in order to have a more extensive view, and keeping in mind that competitive learning methods aim at error minimization or entropy maximization (different kinds of func...

background and aims. adhesive permeability is hindered by application of an additional layer of hydrophobic resin, which increases its concentration within the hydrophilic layer, reduces its affinity to water, and enhances its physical properties. the aim of the present study was to evaluate the effect of a hydrophobic layer on the microleakage of class v composite restorations using different ...

the genetic diversity of a large number of pistachio genotypes grown in iran is not exactly known. most of the studies on genetic diversity of iranian pistachio varieties are based on morphological characteristics or isozyme markers. in the present study, the genetic diversity of selected pistachio cultivars along with some wild species were evaluated by amplified fragment length polymorphism (...

in thirty-three wild cherry (prunus avium l.) accessions from central serbia, tree, leaf, fruit, and stone morphological characters were evaluated during three consecutive years. the goal was to detect relationships between the genotypes and to identify the most useful traits for discrimination among them. the study revealed a high variability in the set of the evaluated wild cherry accessions ...

A new family of glycosylphosphatidylinositol-anchored beta(1-3)glucanosyltransferases (Gelp), recently identified and characterized in the filamentous fungus Aspergillus fumigatus, showed functional similarity to the Gas/Phr/Epd protein families, which are involved in yeast morphogenesis. Sequence comparisons and hydrophobic cluster analysis (HCA) showed that all the Gas/Phr/Epd/Gel proteins be...
