objective(s): it has been reported that the mutation of the pre-core (pc) and basal-core promoter (bcp) may play an important role in the development of hbv-related hepatocellular carcinoma (hcc). in this study the pc and bcp mutations were investigated in chronic hbv patients. materials and methods:in this study, 120 chronic hbv patients from golestan, northeast of iran who were not vaccinated...

Objective(s): It has been reported that the mutation of the pre-core (PC) and basal-core promoter (BCP) may play an important role in the development of HBV-related hepatocellular carcinoma (HCC). In this study the PC and BCP mutations were investigated in chronic HBV patients. Materials and Methods:In this study, 120 chronic HBV patients from Golestan, Northeast of Iran who were not vaccinated...

Background and Objective: BRAF mutations were studied in various populations for prostate carcinoma (PC); however, mutations in BRAF gene are unusual compared to KRAS. Oncogenic activating of BRAF mutations were studied lately in almost 0%-10% of prostate cancer cases. Methods: In this retrospective study, we gathered 100 formalin-fixed ...

conclusions this study indicates that the rate of g1896a mutation at the pc region among hbeag negative patients, in the golestan province of iran, was similar to the average rate encountered in other parts of iran. the pc stop codon mutation was detected in 93.18% of hbeag negative patients. further studies with larger sample sizes are required to elucidate the exact role of these mutations in...

It is remarkable that certain patients with heterozygous protein C (PC) deficiency manifest venous thromboembolism (VTE), whereas others, particularly those belonging to families with homozygous PC deficiency, remain asymptomatic. The goals of the present study of a family, in which the proband had homozygous PC deficiency, were to identify members with and without VTE, to determine the mutatio...

The aim of this study was to explore the prevalence of basal core promoter (BCP) and precore gene (PC) mutations in hepatitis B virus (HBV) isolates among the Nicobarese tribe and their relationship with genotypes and HBeAg status. A total of 726 blood samples were collected from two villages of the Car Nicobar Island where mass vaccination was performed in the year 2000. HBV DNA was isolated a...

287 Indian Dermatology Online Journal | Volume 8 | Issue 4 | July‐August 2017 Sir, We read with great interest the informative case report “Pachyonychia congenita with late onset (PC tarda)” by Sravanthi et al. in the July‐August 2016 issue of the Journal.[1] However, we would like to emphasize certain points regarding the history and current classification system of this rare disorder of kerat...

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...

The 1896 precore (PC) mutation is the most frequent cause of hepatitis B virus e-antigen (HBeAg)-negative chronic hepatitis B virus (HBV) infection. Detection of the 1896 PC mutation has application in studies monitoring antiviral therapy and the natural history of the disease. Identification of this mutation is usually performed by direct sequencing, which is both costly and laborious. The aim...

Paramyotonia congenita (PC) is a rare autosomal dominant neuromuscular disorder characterized by juvenile onset and development of cold-induced myotonia after repeated activities. The disease is mostly caused by genetic mutations of the sodium channel, voltage-gated, type IV, alpha subunit (SCN4A) gene. This study intended to systematically identify the causative genetic variations of a Chinese...
