background: spermatogonial stem cells (sscs) are infrequentself-renewing cells among the type a spermatogoniawithin the seminiferous tubules and are the basis of spermatogenesisin mammalian testis. an adequate number of sscs is aprimary requirement for the study of their behavior, regulation, andfurther biomanipulation. objectives: in this paper, we studiedthe development of the primary co-cult...

the aim of this investigation was to evaluate the use of polypropylene mesh and glycerol preserved bovine pericardium (gbp) to repaire abdominal wall defects in 24 clinically healthy mongrel dogs using inlay and underlay techniques. twenty four healthy mongrel dogs were used in this study. the animals were divided into two main groups according to the type of the prosthetic material used. each ...

showing the occurrence of glass/rubber transition in bovine serum albumin (a globular protein) atlow moisture levels and the occurrence of maillard crosslinking in gelatin in previous works, the importanceof the state of glass or rubber of bsa on the rate and extent of polymerisation, protein solubility, colour andsds page patterns in the presence and absence of ascorbic acid, diketogulonic aci...

staphylococcus aureus is generally regarded as a leading cause of mastitis in dairy cattle. the aim of this study was to investigate the pattern of agr groups and any possible relationship between agr groups and antibiotic resistance among s. aureus strains isolated from bovine mastitis in northeast of iran. for this purpose, a total of 300 bovine mastitic milk samples were taken from dairy ind...

in order to estimate the mean of maternal antibody in calves against bhv-1 (bovine herpes virus type 1), this study was carried out in a population of calves from non-vaccinated dairy cattle at 2 livestock in qazvin province. one hundred thirteen sera out of 512 were collected from 1-4 months unvaccinated calves. we used blocking –percentage of maternal antibodies against bhv-1, which obtained ...

coagulase-negative staphylococci (cons) are often associated with bovine mastitis and may be resistant to antimicrobial therapy. the aim of the current study was to investigate the presence of blaz (responsible for penicillin resistance) and meca (responsible for methicillin resistance) genes among 108 cons belonging to 9 different species isolated from bovine mastitis in seven dairy herds (h1-...

backgrounds and aims: mastitis is a mammalian disease which is considered important due to its potential economic damages. trueperella pyogenesis is one of the important opportunistic pathogens of the mammary glands of cattle. this bacterium can produce acute mastitis infection in dairy cattle. in fact, this bacterium has several virulence genes which contribute to its pathogenicity. therefore,...

background and aims: some nanoparticles can be used in immunoassays to increase sensitivity. this study aimed to evaluate a novel nano-immunoassay based on bovine serum albumin nanoparticles (bsa nps). materials and methods: at first, the nanostructure was synthesized, and then applied as a tag in the nano-immunoassay. then the concentration of β-subunit of human chorionic gonadotropin (βhcg) i...

background & aims of the study: oxidative stress increases platelet-derived growth factor (pdgf) gene expression in endothelial cells that contributes to vascular dysfunction and atherosclerosis. oxidative stress generates by dys-regulated redox balance between ros producing systems and antioxidant systems. also, curcumin (cur) as a main part of turmeric has anti- inflammatory, antioxidant, ant...
