Hidden Markov model methods for stochastic sequential analysis are described and a synergistic union is presented to arrive at a new form of carrier-based communication, where the carrier is not periodic but is stochastic, typically with stationary statistics. HMM with binned duration, and meta-HMM algorithmic methods, are shown to enable practical stochastic carrier wave encoding/decoding, whe...
In recent years, gene therapy has become a promising technology to enhance endothelialization of artificial vascular grafts. The ideal gene therapy requires a gene carrier with low cytotoxicity and high transfection efficiency. In this paper, we prepared a biodegradable cationic copolymer poly(D,L-lactide-co-glycolide)-graft-PEI (PLGA-g-PEI), grafted Cys-Ala-Gly-Trp (CAGW) peptide onto this cop...
Hereditary ataxias (HA) are a group of inherited neurological disorders caused by changes in genes. At least 115 different mutations in the senataxin (SETX) gene causing ataxia have been identified. There are no reports of any SETX gene mutation among the Iranian population. Here we report on two cases with homozygous and heterozygous mutations in which one patient was affected by HA with oculo...
Background: Cystic fibrosis (CF) is a common autosomal recessive disorder that affects many body systems and is produced by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. CF is also the most frequently inherited disorder in the West. The aim of this study was to detect the mutations in the CFTR gene in two Iranian families with CF. Methods: After DNA extractio...
Background: Phenylketonuria as the most common genetic metabolic disorder is the result of disruption of the phenylalanine hydroxylase gene. This study was carried out to explore the phenylalanine hydroxylase gene mutation status of Iranian phenylketonuria patients. Methods: Blood samples were collected from 30 patients, and hot spot areas of the phenylalanine hydroxylase gene, in...
P-glycoprotein (Pgp), a transmembrane efflux pump encoded by the MDR1 gene, transports various lipophilic drugs that enter the cell by passive diffusion through the lipid bilayer. Pgp-expressing multidrug-resistant cell lines are not usually cross-resistant to a hydrophilic antifolate methotrexate (MTX). MTX enters cells primarily through a folate carrier, but passive diffusion becomes the prim...
