background and objectives: bacillus anthracis is one of the most homogenous bacteria ever described. bacillus anthracis 17jb is a laboratory strain. it is broadly used as a challenge strain in guinea pigs for potency test of anthrax vaccine. material and methods: this work describes genetic characterization of b. anthracis 17 jb strain using the snps and mlva genotyping. results and conclusion:...
background and objectives: rheological characteristics of dough are important for achieving useful information about raw-material quality, dough behavior during mechanical handling, and textural characteristics of products. our purpose in the present research is to apply soft computation tools for predicting the rheological properties of dough out of simple measurable factors. materials and met...
passiflora species were known by their anticonvulsant, anxiolytic and sedative activities. the aim of this study was to investigate the chemical composition of the most active leaf extract of passiflora caerulea l. grown in egypt. the ethanolic extract of the leaves exhibited higher activity than aqueous extract as anticonvulsant (63% potency relative to carbamazepine), analgesic (70% potency r...
Thyme is an important medicinal plant in cosmetic, pharmaceutical and food industries. The first step for breeding of thyme is evaluating of genetic variation and relationship between thyme’s accessions. Therefore, the objective of this study was to evaluate morphology, chemical and molecular variation of 13 accessions of Thyme medicinal plant. ANOVA showed significant differences between acces...
Due to their non-toxic nature, biodegradability and production from renewable resources, research has shown an increasing interest in the use of biosurfactants in a wide variety of applications. This paper reviews the characterization of rhamnolipid and sophorolipid biosurfactants based on their hydrophilicity/hydrophobicity and their ability to form microemulsions with a range of oils without ...
Applications of nanowires into future generation nanodevices require a complete understanding of the mechanical properties of the nanowires. A great research effort has been made in the past two decades to understand the deformation physics and mechanical behaviors of nanowires, and to interpret the discrepancies between experimental measurements and theoretical predictions. This review focused...
Accurate characterization of promoter behavior is essential for the rational design of functional synthetic transcription networks such as logic gates and oscillators. However, transcription rates observed from promoters can vary significantly depending on the growth rate of host cells and the experimental and genetic contexts of the measurement. Furthermore, in vivo measurement methods must ac...
The objective of this study was to analyse the population genetic structure of the Persian sturgeon (Acipenser persicus) in Sefidrud and Gorganrud rivers watershed based on the characterization of microsatellite markers during 2006 – 2008. 100 samples of Persian sturgeon were collected from two regions. Four microsatellite loci ( Ls 68 , Spl 168 , Spl 173 and Afu 68 ) were analyzed for the mo...
