semen quality and its relationship to fertility are major concern in animal production. the aim of this study was to assess the relationship between frozen thawed sperm characteristics and fertility following in vivo fertility through artificial insemination(ai). semen samples were collected from four buffalo bulls. semen volume and sperm concentration appeared to be significantly different (p0...

objective(s):  medicinal benefits of quantum dots have been proved in recent years but there is little known about their toxicity especially in vivo toxicity. in order to use quantum dots in medical applications, studies ontheir in vivo toxicity is important.  materials and methods:cdse:zns quantum dots were injected in 10, 20, and 40 mg/kg doses to male mice10 days later, mice were sacrificed ...

objective: the role of herbs against the free radicals have been put forth recently in combating many diseases. the aim of this study was to elucidate the in vitro capacity and in vivo antioxidant properties of sedimental extract of tinospora cordifolia (setc). materials and methods: setcwas subjected to in vitro chemical analysis such as 1,1-diphenyl-2-picrylhydrazyl (dpph), nitric oxide, hydr...

in this study, a medicinal plant, galla rhois (gr), was examined and screened for its anti-helicobacter pylori activity. galla rhois was extracted with 70% ethanol. inhibitory zone tests, as in vitro assays, and an in vivo study using a mongolian gerbil (meriones unguiculatus) model were performed. the safety of the gr extract was then evaluated in an animal study. the galla rhois extract demon...

The chemical shift sensitivity and significant signal enhancement afforded by laser-polarized 129Xe have motivated the application of 129Xe NMR to biological imaging and spectroscopy. Recent research done by our group has used laser-polarized 129Xe in biomolecular assays that detect ligand-binding events and distinguish protein conformations. The successful application of unfunctionalized and f...
