Background and Objectives: Helicobacter pylori is a gram-negative and spiral bacterium that causes stomach and duodenal disease in humans. Because of the presence of disadvantages in antibiotic therapies, increasing efforts have been made to produce effective vaccine for this infection. The aim of this study was to generate a construct carrying the lnT gene and to survey its...
background and aims: newcastle disease virus (ndv) is one of the major pathogen in poultry. vaccination is intended to control the disease as an effective solution nevertheless this virus is a growing threat to the poultry industry. f gene open reading frame (orf) from ndv is 1650 bp, encoding a protein of 553 amino acids that can induce protective immunity alone. the f glycoprotein on the surf...
Background: Gamma -aminobutyric acid (GABA), a non-protein amino acid acts as an inhibitory neurotransmitter in the central nervous system of mammalians. The glutamate decarboxylase (GAD) is responsible for the conversion of L-glutamate to GABA. The human brain has two isoforms of this enzyme, GAD65 and GAD67 that differ in molecular weight, amino acid sequence, antigenicity, cellular location ...

Vaccination is intended to control the disease as an effective solution nevertheless this virus is a growing threat to the poultry industry. F gene open reading frame (ORF) from NDV is 1650 bp, encoding a protein of 553 amino acids that can induce protective immunity alone. The F glycoprotein on the surf...
results this study shows the prepared gene construct is inducible by glucose. gene expression of preproinsulin was observed in muscle tissue of rabbits. conclusions these finding indicated that research in diabetes mellitus gene therapy could be performed on larger animals. objectives the purpose of this study was to construct glucose inducible insulin gene plasmid and use it in the muscle tiss...
Background and Aim: Leishmania major p4 gene is normally expressed during amastigote form of the parasite and can be a good candidate for producing an effective vaccine. The aim of this study is to clone p4 gene in a suitable vector for further vaccine production studies .Materials and Methods: This is an experimental study. Leishmania promastigote was grown in N.N.N. medium and later in th...
background type 1 diabetes mellitus is one of the metabolic diseases that cause insulin-producing pancreatic ß cells be destroyed by immune system self-reactive t cells. recently, new treatment methods have been developed including use of the stem cells, ß islet cells transplantation and gene therapy by viral and non-viral gene constructs. objectives the aim of this project was preparing the n...
Abstract Background and Objective: Increased antibiotic resistant strains and inadequacy of current vaccines against pneumococcal infections necessitate the study of novel protein antigens. It seems that minor autolysin of Streptococcus pneumoniae may have antigenicity. Thus, we aimed at cloning its gene for the first time. Material and Methods: After DNA extraction of Streptococcus pneumoniae ...
Alcanivorax borkumensis is a marine bacterium that has ability to grow on limited substrates that mainly is alkanes. The ability to use wide range of hydrocarbons is advantage of this bacterium to other marine community bacteria. A. borkumensis have two genetic systems for alkane biodegradation. The First system is alkane hydroxylase (alk-B1and alk-B2) and the second system is...
Background: Cholesterol oxidase (CHO) has various clinical and industrial applications. Recently, microbial CHO have received a great attention for their wide usage in medicine. Here, taxonomic characterizations of isolated strain from soil, optimization of the conditions for CHO production and biochemical characterizations of produced CHO enzyme were described. Finally, CHO gene was cloned int...
