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 ...

BACKGROUND Enhanced sarcoplasmic reticulum Ca(2+)-leak via ryanodine receptor type-2 (RyR2) contributes to the pathogenesis of atrial fibrillation (AF). Recent studies have shown that the level of RyR2 protein is elevated in atria of patients with paroxysmal AF, suggesting that microRNA-mediated post-transcriptional regulation of RyR2 might be an underlying mechanism. Bioinformatic analysis sug...

Many viruses alter intracellular calcium homeostasis. The rotavirus nonstructural protein 4 (NSP4), an endoplasmic reticulum (ER) transmembrane glycoprotein, increases intracellular levels of cytoplasmic Ca(2+) ([Ca(2+)]cyto) through a phospholipase C-independent pathway, which is required for virus replication and morphogenesis. However, the NSP4 domain and mechanism that increases [Ca(2+)]cyt...

Clustering analysis (CA) and principal component analysis (PCA) were applied to dynamic Cerenkov luminescence images (dCLI). In order to investigate the performances of the proposed approaches, two distinct dynamic data sets obtained by injecting mice with (32)P-ATP and (18)F-FDG were acquired using the IVIS 200 optical imager. The k-means clustering algorithm has been applied to dCLI and was i...

This technical note describes a robust version of moving averages, that enables reliable monitoring of the evoked potential (EP) signals. A cluster analysis (CA) procedure is introduced to robustify the signal averaging (SA). It is implemented via a Hopfield neural network (HNN), which performs selection of the trials forming a cluster around the current state of the EP signal. The core of this...

Many polymorphisms exist in field bindweed (Convolvulus arvensis L.) populations. These differences that appear especially in their flower and leaf cause to different biotypes of this weed that are different in view of dry weight, rate- and flowering period. This research was accomplished during 2005 to 2006 at Weed Research Department, Iranian Plant Protection Research Institute for identifica...

Twinning is a critical deformation mode in Mg alloys. Understanding twinning (DT) essential to improving mechanical properties of To address the experimentally observed conspicuous hardening effects Mg-1.8Zn-0.2Ca alloys, interactions between {10–12} twin boundaries (TBs) and solute clusters Mg-Zn-Ca alloys were examined via molecular dynamics (MD) simulations. We find that Zn/Ca-containing sho...

tea (camellia sinensis) is one of the most economically important crops and is considered tobe the national drink of iran. although there has been an intensive cytogenetic study of tea in differentregions of the world, there has been no report from iran. therefore, the present investigation was carriedout in order to present the basic cytogenetical features of various tea cultivators grown in t...

having knowledge about genetic relationships among accessions is necessary for developing breeding strategies to produce improved cultivars. in present study, genetic diversity and inter-relationship among 29 genotypes of citrus were comparatively analyzed using morphological and rapd markers. significant variability was observed among citrus genotypes for 61 quantitative and qualitative morpho...
