Interferon was optimally produced in human peripheral leukocyte cultures incubated for approximately 19 hr in the presence of Sendai virus at a multiplicity of 10 to 50 EID(50)/cell. For determining whether deoxyribonucleic acid (DNA) synthesis per se was essential for interferon production, 1-beta-D-arabinofuranosylcytosine (Ara-C), a potent DNA inhibitor was studied for its effect on interfer...
Background: One of the medicinal fungi that has been used in traditional medicine for a long time is the Basidiomycete fungus Fomes fomentarius, which is widely distributed in Iran. Polysaccharides as one of the metabolites of this fungus have anti-inflammatory, anti-diabetic, antibacterial, antioxidant, and anti-cancer properties. Materials & Methods: Optimization of independent variable...
CONTEXT The major motivation for the preparation of the plasma derived biological medicine was the treatment of casualties from the Second World War. Due to the high expenses for preparation of plasma derived products, achievement of self-sufficiency in human plasma biotechnological industry is an important goal for developing countries. EVIDENCE ACQUISITION The complexity of the blood plasma...
BACKGROUND Toluene diisocyanate (TDI) is used in industry in the production of flexible polyurethane foam, commonly a mixture of the 2,4- and 2,6- isomers. The production process may lead to exposure to diisocyanates which are associated with respiratory disease. A method has been available for the determination of TDI biomarkers in urine for some years. AIMS To explore the usefulness of urin...
this research, for lowering the use of chemical fertilizer, was carried out using combinations of biological and chemical fertilizer on bean in rasht region in 2012 growing season. the experiment was conducted based on randomized complete blocks design with 12 treatments and three replications. experimental treatments included: control (no fertilizers and no inoculants), chemical fertilizers (n...
abstract background and aims: the cydia pomonella granulovirus (cpgv) is a baculovirus and very effective biological control agent against apple pest, codling moth, cydia pomonella l. especially for healthy organic apple production and protection. not only, screening of cpgv isolates via biochemical variation, but also their biological variation is practically necessary. however, the bioassay...
Biogas technology has been used quite extensively to generate renewable energy from organic wastes while also recycling nutrients in the wastes and reducing harmful emissions. However, the challenges of low biogas yield from recalcitrant and inhibitory solid wastes together with high construction and operation costs of bioreactors have impeded optimal performance through this process. Additiona...
Beef and its products are an important source of nutrition in many human societies. Methods of production vary and include the use of hormonal compounds ('hormones') to increase growth and lean tissue with reduced fat deposition in cattle. The hormonal compounds are naturally occurring in animals or are synthetically produced xenobiotics and have oestrogenic (oestradiol-17beta and its esters; z...
Luteinizing hormone as other glycoprotein hormones is characterized by a heterodimeric structure composed a common α-subunit noncovalently linked to a specific β-subunit. The correct conformation of the heterodimer is important for efficient secretion, hormonal-specific post-translational modifications, receptor binding and signal transduction. To determine whether αand βsubunits can be synthes...
