the prevalence of obesity as one of the most health concerns has increased globally. this kind of disease has been accounted for several diseases such as type 2 diabetes, different types of cancer, heart disease, and alzheimer. obesity is a multifactorial disease that both environmental factors and genetics play important role in its susceptibly. in molecular biology, characterization of the ad...

Based on the limited resources available to algal flora in Yazd province in the center of Iran, cultivation, purification and identification of soil algae from seven sites was performed in summer 2013. The soil samples were processed for analysis of Cd, Pb contents. The present paper attempts to analyze survey of soil blue-green algal identification in different types of stations, using morphol...

Background: Avian rotaviruses are one of the important agents of enteritis in birds and have a worldwide distribution. These viruses have an important role in runting and stunting syndrome in chickens. Objectives: The aim of this study was detection and molecular characterization of avian rotaviruses in broiler farms in Guilan province. Methods: In this study, 100 samples were collected on diff...

background: malassezia are dimorphic, lipid-dependent yeasts, which are responsible for causing several cutaneous and sys­temic conditions. although cyclophilins (cyps) are highly conserved cytosolic proteins that catalyze the peptidyl-prolyl cis-trans isomerazation reaction before protein folding process, it has been suggestive of an allergen in a few numbers of fungi such as aspergillus fumig...

  Avian metapneumovirus (aMPV) represents one of the most prevalent diseases of poultry mainly in combination with other pathogens, and it is increasing among chickens.  In the present study, the detection and characterization of an aMPV subtype B strain circulating in broiler flocks based on fusion (F) gene. In phylogenetic analysis, the isolates are located in B subtype cl...

Background: Members of this genus Aureobasidium are ubiquitous microorganisms which can be isolated from wide ranges of substrates such as plant materials (phyllosphere, plant debris, bark, roots, fruits and wood), soil, dead wood, air, and as rare etiologic agent of pheohyphomycosis, keratomycosis, septicemia, peritoneal sepsis, and dermatological infections in human. Very little is known on t...

abstract background: fascioliasis, caused by fasciola hepatica and f. gigantica , has medical and economic importance in the world. molecular approaches comparing tradi­tional methods using for identification and characterization of fasciola spp. are precise and reliable. the aims of current study were molecular characterization of fasciola spp. in west azerbaijan province, iran and then compar...

Hemicelluloses were isolated from hybrid poplar with the single-step alkaline extraction. Neutralization and subsequent ethanol precipitation were used to recover them. Their structures were investigated using sugar analysis, Fourier transform infrared and (13)C nuclear magnetic resonance spectroscopy. The hemicelluloses were characterized by particle size analyzer, gel permeation chromatograph...

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 ...
