objective: to evaluate the efficacy of in vitro sperm activation (isa) using non-liquefied versus liquefied asthenozoospermic semen samples for improvement of sperm parameters. materials and methods: fifty six oligoasthenozoospermic (oa) patients (age range: 22-44 years; mean: 32.089 years) were enrolled in this study. oa patients were classified according to type of infertility. also, duration...
traumatic brain injury (tbi) is caused by rapid deformation of the brain, resulting in a cascade of pathological events and ultimately neurodegeneration. in vitro models of tbi can help us to describe the pathobiological mechanisms. in vitro models of brain injury support a platform for performing repeatable, well-controlled, environmentally isolated experiments. other advantages of in vitro mo...
Present study was carried out to study the effect of growth stage on chemical composition and degradability parameters of DM, NDF and CP in bersim clover (Trifolium repens). Plant samples were collected and studied at 5 stages of vegetative growth stage (second week, fourth week, sixth week, eighth week, tenth week). Ruminal degradability of samples was determined by in situ technique using t...
Background Male infertility management has made significant progress during the past three decades, especially after the introduction of intracytoplasmic sperm injection (ICSI) in 1992. However, many boys and men still suffer from primary testicular failure due to acquired or genetic causes. New and novel treatments are needed to address these issues. Spermatogenesis originates from spermatogon...
limited data exist about the production of extruded linseed as a feed ingredient in farm animal nutrition. the objective of this study was to produce and evaluate extruded linseed mixed with alfalfa hay, pistachio by-products, and sugar beet pulp or corn grain in different proportions of linseed: alfalfa hay: pistachio by-products at ratios of 70:15:15, 70:20:10, 70:10:20, and 80:10:10 for qual...
Six sheep were fed twice a day on a different ratio of sheep pellets and hay (20:80 (diet 1), 40:60 (diet 2) and 80:20 (diet 3)) in a replicated Latin square design to study the effect of the host diet on the bacterial concentration of ruminal liquor and in vitro gas production degradability parameters of cellulose, glucose and hay. Bacterial DM, bacterial absorbance and the volume of gas produ...
A study was conducted to investigate the effect of follicular size (small,
چکیده این پژوهش به منظور بررسی تغییرات ترکیب شیمیایی و بهبود قابلیت هضم سیلوی علف نی با افزودن اوره و تفاله مرکبات به روش in vitro و in situ انجام شد. جهت بررسی تغییرات ترکیبات شیمیایی، ابتدا 50 کیلوگرم علف نی جمع آوری و به قطعات 2-4 سانتی متری خرد گردید. سپس علوفه نی با سطوح (5/2 و 5 درصد اوره و 5، 10 و 15 درصد تفاله مرکبات) مخلوط و در سطل های پلاستیکی سیلو گردید. ترکیبات شیمیایی اندازه گیری...
Determination of microbial degradability of N is important in formulating a sound supplementation strategy for efficient utilisation of basal as well as supplementary diet components. In vitro degradability of N (IVDN) from tannin-containing browses (Acacia cyanophylla, Acacia albida, Acioa barteri and Quercus ilex) and two herbaceous legumes (Desmodium intortum and Desmodium uncinatum) was det...
