A ruminal in situ experiment using three fistulated ewes was conducted to determine dry matter (DM) and crude protein (CP) degradation of steam–flaked broomcorn (SFBr), ground broomcorn (GBr) and ground barley (GB). Grain samples were suspended in the rumen of sheep for 0, 2, 4, 8, 16, 24 and 48 h. Nylon bags were washed with tap water after removal. Effective degradability of DM at outflow rat...
این مطالعه به منظور تعیین اثر عمل آوری تفاله زیتون با قارچ نوروسپورا سیتوفیلا بر ترکیب شیمیایی، کل ترکیبات فنولی و تانن، خصوصیات فیزیکی قابلیت هضم و تجزیه پذیری مواد مغذی با استفاده از دو روش in vitro و in situ انجام گرفت.آزمایش در قالب طرح کاملا تصادفی انجام شد. در مطالعه حاضر با عمل آوری تفاله زیتون با قارچ نوروسپوراسیتوفیلا غلظت پروتئین خام افزایش یافت (05/0p<). در حالی که مقدار ماده خشک، ال...
background: it has been claimed that by using different washing methods, the sperms can be separated according to size, motility, density, chromosomal content and surface markings and charge. these methods also reduce sperm chromatin deficiencies and screen the sperms before applying in assisted reproduction techniques. objective: this study compared simple density gradient methods and a combin...
purpose: to evaluate and compare tear secretion and tear film instability following laser in situ keratomileusis (lasik) and laser assisted subepithelial keratectomy (lasek). methods: in a randomized clinical trial, 30 eyes of 15 patients underwent lasik and 30 eyes of 15 patients underwent lasek to correct myopia. tear secretion and tear film instability were tested preoperatively, 2 and 6 wee...
perrault's syndrome (p.s.) is rare. the combination of gonadal dysgenesis and hearing loss was accompanied by 46,xxkaryotype in three sisters with parental consanguineous marriage. genetic investigation revealed normal female karyotype, positive liarr and negative fluorescence ipj-bodies, which was confirmed by molecular study on the basis of fluorescence in situ hybridization (pish), with appl...
background: acute promyelocytic leukemia (apl) is a subclass of acute myeloid leukemia. the chromosomal aberration in 95% of apl cases is t(15; 17) (q22; q21), which prevents cell differentiation. characterization of the underlying molecular lesion is valuable in determining optimal treatment strategy. the goal of this study was to develop a new and powerful flow- fish technique to detect the l...
purpose : to assess and to compare stromal and endothelial changes at the cellular level in patients who had photorefractive keratectomy (prk) and laser in situ keratomileusis (lasik) using in vivo confocal microscopy methods : in this semiexperimental study, 32 eyes of 16 patients (4 males and 12 females) with low to moderate myopia [-1.00 to -4.50 diopters (d)] or low to moderate myopic astig...
atom transfer radical polymerization of styrene (st) and methyl methacrylate (mma) was performed at 90oc in the absence and presence of nanoclay (cloisite 30b). trichloromethyl-terminated poly(vinyl acetate) telomerand cucl/ pmdeta were used as a macroinitiator and catalyst system, respectively. the experimental results showed that the atom transfer radical polymerization of st and mma in the a...
During the past 15 years researchers have made great strides in understanding the metabolism of hydrocarbons by anaerobic bacteria. Organisms capable of utilizing benzene, toluene, ethylbenzene, xylenes, alkanes, and polycyclic aromatic hydrocarbons have been isolated and described. In addition, the mechanisms of degradation for these compounds have been elucidated. This basic research has led ...
