this research was conducted in two protect and destroy region in the middle zagros, in illam province. in order to identification of ecological species group and evaluate density of regeneration, effect of many factors such as protection, vegetation, physiographic factors, physical and chemical properties of soil in study locations were studied. to achieve these purpose number of 54 plots using...
the history of plant’s used for mankind is as old as the start of humankind. initially, people used plants for their nutritional proposes but after the discovery of medicinal properties, this natural ?ora became a useful source of disease cure and health improvement across various human communities. berberis vulgaris is one of the medicinal plants used in iranian traditional medicine. berberis ...
Background: Outer inflammatory protein A (OipA) is one of the important adhesins of H. pylori and a valuable candidate for vaccine development. Its gene is under "on-off" switch status which correlates with OipA protein expression. Objectives: We aimed to obtain a recombinant OipA clone (with "on" status) from an Iranian clinical isolate. Materials and Methods: A clinical H. pylori-isolate demo...
Dendrimer based nanostructures have been increasingly used for delivery of drugs/genes. These nanosystems, as non-viral gene delivery systems, were shown to have relatively high transfection efficiency despite exerting somewhat cytotoxicity. In this current investigation, poly(amido amine) (PAMAM) dendrimers, generation (G) zero to five, PEGylated PAMAM G3 and a new quaternized PAMAM G4 ...
Background and objectives: Haplophyllum canaliculatum isan endemicand endangeredIranian plant from Rutaceae family. The object of this work was to study the volatile production in established shoot and callus cultures of Haplophyllum canaliculatum as well as isolation, identification and sequencing of 18S rRNA gene from callus culture. ...
Determination of RT-PCR detection limit of live and dead Salmonella cells in raw and sterilized milk
The objective of the current study was to evaluate the reproducibility of a reverse transcriptase PCR (RT-PCR)-based technique to differentiate viable and dead Salmonella cells in raw and sterilized milk. The microorganism was initially inoculated into the milk samples followed by incubating at 37°C for 4 h prior to inactivation by heat at 80°C for 10 min. The treated and non-treated samples we...
Hydrogen sulfide (H2S) has been shown to protect the gastric mucosa through several protective mechanisms but till now its effect on mRNA expression of sodium bicarbonate cotransporter 1 (NBC1), trefoil factor1 (TFF1) and trefoil factor2 (TFF2) was not investigated. This study was aimed to evaluate the effect of H2S on mRNA expression of NBC1, TFF1 and TFF2 in rat gastric ...
background: helicobacter pylori strains have two classical virulence genes, the cytotoxinassociated a ( caga ) gene and the vacuolating cytotoxin a ( vaca ) gene, which are located in the cag pathogenicity island ( cag pai). serum immunoglobulin g (igg) antibodies to h. pylori , especially, the caga antigen may be a reliable marker for selection of dyspeptic patients for upper endoscopy. method...
abstract the present study investigated the effects of task types and involvement load hypothesis on incidental learning of 10 target words (tws) in junior high schools (jhss) in givi, ardabil. the tasks deployed in this study were two input-based tasks (reading plus dictionary use with an involvement index of 3, and reading plus gap-fill task with an involvement index of 2), and one output-ba...
Mycoplasma synoviae (MS) is a pathogen responsible for respiratory and locomotor disorders and causes major economic losses in poultry industry. Early and accurate diagnosis of MS infection plays a major role in control of the infection. This study was conducted to characterize Iranian field isolates of MS isolated from broiler chickens of West Azarbaijan province (Northwest of Iran), ...
