Development of an egg-white bioassay for monitoring biotin levels in urine and serum.

چکیده
This article reports on the development of a simple and cost-effective bioassay for the detection of biotin in urine and serum, based on the very selective binding of avidin and biotin. Avidin was allowed to react without isolating it from egg white. Egg white was treated with the dye HABA, which binds to avidin. Upon subsequent treatment with biotin, HABA is released due to the high affinity of biotin to avidin. The amount of HABA released is proportional to the amount of biotin used.

The success of conception in buffalo is greatly dependent on precise estrus detection and time of artificial insemination (AI). Various visual, behavioral, biochemical and gyneco-clinical parameters have been tracked closely and a cost-effective combinatorial model has been developed to detect estrus in buffaloes. Pheromones play pivotal roles in reproduction and behavior of mammals. Urine, an ...

A key determinant of the relationship between diet and longevity is the balance of protein to carbohydrate in the diet. Eating excess protein relative to carbohydrate shortens lifespan in solitary and social insects. Here we explored how lifespan and behavior in ants was affected by the quality of protein ingested and the presence of associated antinutrients (i.e. compounds that interfere with ...

Background & Objective: There are many common infections and inflammations among people over the world. This demands an affordable and reliable test with high sensitivity/specificity to predict or confirm the diagnosis of such cases in routinely clinical practice. In the present study, we aimed to find any potential correlation between serum levels of GGT and CRP- Q and/or hs- CRP and ...

Background and purpose: Ulcerative colitis (UC), a subtype of inflammatory bowel diseases (IBD), is an immune-mediated chronic intestinal condition. Changes in the copper (Cu) and zinc (Zn) concentrations have been reported previously in IBD. Due to controversial results, the aim of this study was to evaluate and compare serum and urine levels of Zn and Cu in patients with UC and control group....
