A serological survey was carried out to determine the prevalence rate of bovine viral diarrhea virus (BVDV) infections in water buffalo (Bubalusbubalis) in Ahvaz, which is the center of the Khouzestan province in Iran. For this purpose, blood samples were taken from 310 slaughtered buffaloes at the abattoir. Sera were tested via the serum neutralization test. Serum neutralization was performed ...

in this study, we examined the antioxidant activities of methanolic extract of three endemic species of salvia from iran (s. lachnocalyx, s. reuterana and s. sahendica) employing various established in vitro systems including ferric reducing antioxidant power, trolox equivalent antioxidant capacity assay and scavenging of 1,1-diphenyl-2-picrylhydrazyl radical. the results revealed that s. reute...

Conglutinin is a high-molecular-weight mammalian lectin which binds in a calcium-dependent manner to cell-surface-bound complement fragment iC3b, yeast cell-wall extract and terminal non-reducing N-acetyl-dglucosamine, mannose and fucose residues. This protein, originally detected in bovine serum, belongs to the family of collectins, which are effector molecules in innate immunity. Conglutinin ...

Following suggestions that transferrin present in fetal-bovine serum, a common supplement used in tissue-culture media, may not bind well to human cells, we have isolated the protein and investigated its interaction with both human and bovine cells. Bovine transferrin bound to a human cell line, K562, at 4 degrees C with a kd of 590 nM, whereas human transferrin bound with a kd of 3.57 nM, a 16...

Access to autologous Schwann cells is limited due to lack of donor site and its difficult isolation and culture. Therefore, one of the possible ways to obtain to Schwann cells is to differentiate mesenchymal stem cells into glial pathway using various materials and protocols. The aim of this study was to compare the effects of fetal bovine serum and human serum on Schwann cell differentiation o...

9-beta-d-Arabinofuranosyladenine (ara-A) was deaminated to 9-beta-d-arabinofuranosylhypoxanthine by adenosine deaminase present in fetal bovine serum, newborn calf serum, and calf serum used to supplement tissue culture media. Heating newborn calf serum or calf serum for 12 h at 56 C completely eliminated the enzymatic deamination of ara-A. The deaminase activity associated with fetal bovine se...

The supramolecular aggregation processes occurring on metallic (aluminum and gold) surfaces in aqueous solutions of bovine serum albumin (BSA) during drying were studied using advanced scanning electron microscopy (SEM). possible mechanism for the formation amazing intricate fractal structures was proposed based analysis SEM images, size distribution diagrams EDX-scanning element maps.

to investigate the igg content and its variations in uterine fluid (uf) during the estrous cycle of the cow and to compare them with those of the blood serum (s), six pairs of serum and uf samples for each phase of the cycle selected out of 240 bovine genital tracts and blood samples were collected from urmia abattoir. the uf samples were collected by gentle scraping of the endometrium using a ...
