for induction of ruminal acidosis, 10 clinically healthy three years old non pregnant female sheep were selected. prior to the infusion of sucrose (0 hour), rumen and blood samples were obtained in order to determine baseline rumen and blood ph, respectively. electrocardiogram (ecg) was also recorded. acute ruminal acidosis was induced experimentally with sucrose at a dose of 18g kg-1 body weig...
We aimed to investigate the application of combined mechanistic pharmacokinetic (PK) and pharmacodynamic (PD) modeling and simulation in predicting the domperidone (DOM) triggered pseudo-electrocardiogram modification in the presence of a CYP3A inhibitor, ketoconazole (KETO), using in vitro-in vivo extrapolation. In vitro metabolic and inhibitory data were incorporated into physiologically base...
Walnut consumption produces beneficial cardiovascular effects. The aim of the present study is to compare the effects of meat enriched in walnut paste (WM) and low-fat meat (LM) consumptions on platelet aggregation, plasma thromboxane A2 (TXA2, measured as TXB2), prostacyclin I2 (PGI2, as 6-keto-PGF1alpha) and the thrombogenic ratio (TXB2/6-keto-PGF1alpha) in volunteers at high CVD risk. Twenty...
We investigated the effects of prostaglandins (PG) E2, PGD2, PGI2, and its metabolites 6-keto-PGE1 and 6-keto-PGF1 alpha, and U46619 (stable analogue of the PG endoperoxide, PGH2) administered either intravitreally or topically on intraocular pressure (IOP), pupil diameter, aqueous protein, and the entry of polymorphonuclear cells (PMNs) in the aqueous. PGE2, 6-keto-PGE1, U46619, and PGI2 incre...
Aldo-keto reductase family 1 member C3 has recently been regarded as a potential therapeutic target in castrate-resistant prostate cancer. Herein, we investigated whether berberine delayed the progression of castrate-resistant prostate cancer by reducing androgen synthesis through the inhibition of Aldo-keto reductase family 1 member C3. Cell viability and cellular testosterone content were mea...
Relative bioefficacy and toxicity of Met precursor compounds were investigated in young chicks. The effectiveness of DL-Met and 2-keto-4-(methylthio)butyric acid (Keto-Met) to serve as L-Met precursors was quantified using Met-deficient diets of differing composition. Efficacy was based on slope-ratio and standard-curve methodology. Using L-Met as a standard Met source added to a purified diet,...
change of the tautomeric preference for radical cation of pyruvic acid. dft studies in the gas phase
keto-enol tautomerism was investigated for ionized pyruvic acid using the dft(b3lyp) method and the larger basis sets [6-31++g(d,p), 6-311++g(3df, 3pd) and aug-cc-pvdz]. change of the tautomeric preference was observed when going from the neutral to ionized tautomeric mixture. ionization favors the enolization process (ketoenol) of pyruvic acid, whereas the ketonization (ketoenol) is preferred ...
Oxidative decarboxylation and transamination of 1-14C-branched chain amino and alpha-keto acids were examined in mitochondria isolated from rat heart. Transamination was inhibited by aminooxyacetate, but not by L-cycloserine. At equimolar concentrations of alpha-ketoiso[1-14C]valerate (KIV) and isoleucine, transamination was increased by disrupting the mitochondria with detergent which suggests...
forty two small ruminants, 26 (61.90%) sheep and 16 (38.10%) goats were treated for rumen acidosis. 19 (45.24%), 12 (28.57%), 6 (14.29%) and 5 (11.90%) animals had eaten apple, cooked rice (wazwan left over) turnip and chapatti respectively and manifested clinical form of ruminal acidosis with, 2.86%; (n=18) as mild (rumen fluid ph=6.32 ±0.09316), 38.09%;(n=16)moderate (rumen fluid ph=5.71 ±0.0...
to estimate the prevalence of subacute ruminal acidosis (sara) in dairy cows, a total of 196 ruminalfluid samples were drawn by rumenocentesis from 10 dairy herds of khorasan razavi province, northeast ofiran. two groups of 12 cows, early lactation and mid-lactation cows were sampled in each dairy herd andruminal ph was determined immediately using a portable ph-meter. a total of 54 cows (27.6%...
