Passage of bovine serum albumin (BSA) into unimplanted rabbit blastocysts was studied using intravenous or intrauterine injection of the mother and in vitro cultivation of 5-day blastocysts. BSA concentration in blastocyst fluid was measured using a quantitative radial immunodiffusion method and confirmed by double diffusion in agar. Intravenous injection of up to 200 mg/kg body weight produced...

The present work was designed to study the effect of different concentrations of bovine serum albumin (BSA) in extender on post-thaw quality of buffalo spermatozoa. Semen was collected from three buffalo bulls with artificial vagina (42°C) for three weeks (replicates). Qualifying semen ejaculate from each bull was split into five aliquots and diluted in tris-citric egg yolk extender containing ...

The aim of this investigation was to assess the effect of different antioxidants on the motility andmembrane integrity of the ram semen during storage at 5ºC for 0, 12, 24, 48 and 72 hrs after collection anddilution. A total of 57 ejaculates from 12 Bakhtiary rams was collected by artificial vagina and were extended1 : 3 with egg yolk-citrate buffer, which was containing one of the following an...

Optimal conditions were determined for photophosphorylation and reduction in mature chloroplasts from Phaseolus vulgaris var. Red Kidney. Bovine serum albumin (BSA) at 1 mg/ml and various sulfhydryl reagents (0.1-0.5 mm) greatly enhanced cyclic and noncyclic phosphorylation, but had little effect on photoreduction. BSA and reduced glutathione also stimulated cyclic phosphorylation in spinach ch...

Adsorption of Bovine Serum Albumin (BSA) onto calcium Hydroxyl Apatite (HA), Ca10PO4(OH)2, has been studied by Ultra Violet (UV) spectroscopy. The adsorption isotherms of BSA onto the HA surface at 291.7 K and 303.2 K were satisfactorily presented by Langmuir equation and the evaluated parameters are reported. The specific surface area of H...

Terahertz spectroscopy was used to study the absorption of bovine serum albumin (BSA) in water. The Diamond Light Source operating in a low alpha mode generated coherent synchrotron radiation that covered a useable spectral bandwidth of 0.3-3.3 THz (10-110 cm(-1)). As the BSA concentration was raised, there was a nonlinear change in absorption inconsistent with Beer's law. At low BSA concentrat...

The prevalence of goitre in areas with mildly excessive iodine in drinking-water is still under debate. The aim of the present study was to explore the prevalence of goitre and its epidemiological characteristics in these areas using WHO criteria. To this end, three towns with a median water iodine (MWI) of 150-300 μg/l were selected randomly in Hengshui City of Hebei Province of China, and one...

The effects of lipid-rich bovine serum albumin (LR-BSA) on the development of porcine blastocysts produced in vitro were examined. Addition of 0.5 to 5 mg/ml LR-BSA to porcine blastocyst medium (PBM) from Day 5 (Day 0 = in vitro fertilization) significantly increased the hatching rates of blastocysts on Day 7 and the total cell numbers in Day-7 blastocysts. When Day-5 blastocysts were cultured ...

Can creatinine clearance in children clear the indexing GFR with BSA from the charge of errors? We read with interest the article of Delanaye and colleagues stating that indexing glomerular filtration rate (GFR) with body surface area (BSA) required mathematical prerequisites to be satisfied, even though many studies reported they were not [1]. Although not the gold standard to measure GFR, cre...

The present study was conducted to evaluate the mechanism by which n-3 PUFA regulates the inhibitor of κBα (IκBα)/NF-κB/muscle RING finger 1 (MuRF1) pathway in C2C12 myotubes. After treatment with 150, 300 or 600 μm-α-linolenic acid (ALA) or -EPA for 24 h in C2C12 myotubes, the levels of phosphorylated IκBα (p-IκBα) and total IκBα were measured by Western blot. Compared with the bovine serum al...
