Background: In food industry, carotenoids are used as food colorants conferring yellow to red color. This research was designed to study on lipid and β-carotene production by Rhodosporidium diobovatum cultured with different Carbon to Nitrogen (C/N) ratios. Methods: R. diobovatum was cultured in a medium containing 40 g/l glucose (as the carbon source) and different C/N ratios (20, 50, and 80)...
we have recently synthesized ti(bh4)3(thf)3 and v(bh4)2(tmeda)2 complexes. the reaction of ticl3(thf)3 with nabh4 in dry thf gave flat blue crystals, ti(bh4)3(thf)3. the reaction of vcl3 with nabh4 in presence of n, n, n', n'- tetramethylethylenediamine, tmeda, produced violet crystals, v(bh4)2(tmeda)2. vibrational and magnetic properties of ti(bh4)3(thf)3 and v(bh4)2(tmeda)2 have been studied.
Background: A licensed vaccine against hepatitis C virus (HCV) has not become available to date. The stability and antigenicity of a targeted synthesized recombinant fusion protein consisting of a truncated core and NS3 (rC/N) of HCV had been predicted. Although safe antigens, recombinant proteins are not efficacious vaccines without adjuvants. The present study evaluated the immunogenicity of ...
FK506 and FK506-derived inhibitors of the FK506-binding protein (FKBP)-type peptidylprolyl cis/trans-isomerases (PPIase) display potent neuroprotective and neuroregenerative properties in various neurodegeneration models, showing the importance of neuroimmunophilins as targets for the treatment of acute and chronic neurodegenerative diseases. However, the PPIase activity targeted by active site...
Background and objectives: The incidence of candiduria caused by Candida spp. has increased in recent years, particularly in hospitalized patients. Candiduria is most commonly caused by Candida albicans; however, an increase in the prevalence of non-albicans species has been observed during last decades. This study aimed at molecular identification of Candida species isolated from candiduria in...
nanotechnology is a general term which is related with field of all advanced science term that generally predicates with all modern technologies which consider nanoscales. improvement in the quality of products by adding some nanoparticles and study of their behavior in the presence of these nanoparticles have been obtained in many researches. on the other hand numerous demands for sowing ...
materials and methods the expression of hyaluronidase antigenic fragments was optimized using iptg concentration, time of induction, temperature, culture, and absorbance of 0.6-0.8-1 at 600 nm. afterwards, the expressed proteins were purified and the enzymatic activity was assessed by turbid metric method. results data indicated that maximum protein is produced in od = 0.8, 0.5 mm isopropyl β-d...
utopia has, for four centuries, accompanied that hope of progress and that striving for betterment. it now straggles against a widespread sense that this has been an illusion, or an impossible dream. the utopian idea can never entirely disappear, but utopia as a form of the social imagination has clearly weakened. if it cannot instill its vision in the public consciousness, the consequences...
