background in this study, we evaluated the prevalence of the most common mutations occurring in enhancer ii (enhii), basal core promoter (bcp), precore (pc), and core (c) regions of hepatitis b virus (hbv) genome. objectives we also investigated the correlation between hbv variants, their genotypes, and patients’ hbe antigen (hbeag: soluble shape of the capsid antigen) status patients and metho...
a problem of computer vision applications is to detect regions of interest under dif- ferent imaging conditions. the state-of-the-art maximally stable extremal regions (mser) detects affine covariant regions by applying all possible thresholds on the input image, and through three main steps including: 1) making a component tree of extremal regions’ evolution (enumeration), 2) obtaining region ...
Wheat is a crop with spring and winter types and wide adaptability to different climate conditions. The wide adaptability of wheat is mainly controlled by three groups of genetic factors and among them vernalization (VRN) genes play pivotal role in determining spring and winter types. In this study, 395 Iranian wheat landraces were characterized with specific primer pairs designed based on VRN-...
We present a new statistical approach for eukaryotic polymerase II promoter recognition. We apply stochastic segment models in which each state represents a functional part of the promoter. The segments are trained in an unsupervised way. We compare segment models with three and five states with our previous system which modeled the promoters as a whole, i.e. as a single state. Results on the c...

Introduction: X-ray diffraction studies have revealed that guanines in a DNA stands may be arranged in quartet and form a structure called G-quadruplexs. Bioinformatics studies suggested the formation of G-quadruplex structure in human crucial genes, including Wilms tumor 1 (WT1). The aim of this study was to in silico analysis of the guanine-rich sequence in the promoter region of the WT1 gene...
In this study, in order to find the suitable tuber promoter, an experiment was conducted in Shahid Beheshti University in 2018. For this purpose, promoter sequences of different tuberous plants were searched at NCBI. Sequences were multiple-aligned and the target primers designed from conserved regions. PCR analysis confirmed the presence of the desired promoter in plants of sweet potato a...
background: peroxisome proliferator activated receptor gamma (pparγ), a member of nuclear receptor superfamily, comprises two isoforms in mouse. these two isoforms are encoded by different mrnas, which are arisen by alternative promoter usage. there are two promoter regions upstream of pparγ gene. a 3 kb fragment, containing several transcription factor binding sites, acts as pparγ1 promoter re...
