in this study, the nutritive values of treated walnut hull by neurospora sitophila were evaluated. the chemical composition of samples was evaluated by laboratory analysis.in vitrodigestibility experiment was done to determine digestibility coefficients of dry matter, organic matter and also digestible organic matter in dry matter (domd) to estimate the metabolizable energy (me) content oftreat...

an in vitro experiment was conducted to study the effect of non-fiber carbohydrates (nfc) on ruminaldisappearance kinetics of dry matter (dm) and neutral detergent fiber (ndf) of alfalfa hay, wheat bran andunmolassed sugar beet pulp. non-supplemented or nfc supplemented samples [70 mg/g dm of each feedsample as sucrose (su) or starch (st) or su + st as 1:1] were incubated in bottles containing ...

the first purpose of this study is to present an alternative robust model in order to describe ruminal degradation kinetics of forages and to minimize the fitting problems. for this purpose, the korkmaz-uckardes (ku) model, which has a logarithmic structure, was developed. the second purpose of this study is to estimate, by using the korkmaz-uckardes (ku)model, the parameters tp (the time to pr...

The breakdown of 5-fluoro-2'-deoxyuridine (FdUrd) to 5-fluorouracil (FUra) is catalyzed by the pyrimidine nucleoside phosphorylases, uridine phosphorylase and thymidine phosphorylase. The effects of nucleoside phosphorylase inhibitors on FdUrd and FUra elimination by the isolated perfused rat liver were investigated. The inhibitor was injected into the perfusion reservoir 5 min before FdUrd or ...

The photocatalytic degradation of Diamond green B, a triarylmethane dye, has been investigated in aqueous heterogeneous solutions containing TiO2 nano- particles as photocatalysts. The factors effective on the degradation of Diamond green B, such as the amount of catalyst, the original concentration of dye, the effect of pH and illumination time were investigated under 400 W high pressure mercu...

AB S T R A C T Insulin-LuI was administered intravenously to normal subjects, to patients with maturityonset diabetes and normal renal function, and to nondiabetic patients with renal failure. The ensuing plasma disappearance curves of immunoprecipitable radioactive insulin were determined, and these data were analyzed in a variety of ways. Firstly, fractional irreversible loss rates of insulin...

Southern crabgrass (Digitaria ciliaris [Retz.] Koel.) is often viewed as an undesirable weed, largely because it encroaches upon field and forage crops, gardens, and lawns. However, visual observations of livestock grazing mixed-species pastures suggest that cattle seem to prefer crabgrass to many other summer forages. The objectives of this study were to assess the nutritive value of crabgrass...

The combined model approach uses kinetic analysis of both plasma insulin and C-peptide dynamics to estimate prehepatic insulin secretion rates and parameters of insulin and C-peptide kinetics. The original model used single-compartment kinetics to describe both insulin and C-peptide despite knowledge that C-peptide follows two-compartment kinetics. The performance of the model under rapidly cha...

The proteolysis kinetics of intact proteins by nonspecific proteases provides valuable information on transient partial unfolding of proteins under native conditions. Native-state proteolysis is an approach to utilize the proteolysis kinetics to assess the energetics of partial unfolding in a quantitative manner. In native-state proteolysis, folded proteins are incubated with nonspecific protea...
