The application of urea-based selective catalytic reduction products (i.e., Urea-SCR) provides a NOx and, therefore, minimizes pollution emissions from vehicles fueled by diesel. Such can be easily found in the market; however, they are often susceptible to adulteration, mainly terms urea content and dilution with non-mineralized water. In this study, we propose simple, low-cost, disposable, st...

A study was conducted to evaluate Met requirements of late-gestation beef cows consuming low quality forages on the premise that inadequate supply of metabolizable AA may limit protein accretion during pregnancy. Five ruminally cannulated, multiparous late-gestation beef cows (490 +/- 27 kg), of predominantly Angus (> or =75%) with Hereford and Simmental breeding, were used in a 5 x 5 Latin squ...

We evaluated the effect of increasing amounts of rumen-degradable intake protein (DIP) on urea kinetics in steers consuming prairie hay. Ruminally and duodenally fistulated steers (278 kg of BW) were used in a 4 x 4 Latin square and provided ad libitum access to low-quality prairie hay (4.9% CP). The DIP was provided as casein dosed ruminally once daily in amounts of 0, 59, 118, and 177 mg of N...

Inceptisol soil is an agricultural land in Indonesia, which widely distributed, but has a problem, namely the element of N relatively low, so it necessary to carry out proper cultivation techniques, one through provision balanced fertilizers, organic fertilizers aim improve fertility and reduce use NPK fertilizer. This study aims determine effect various kinds sometimes goat urea fertilizer on ...

ABSTRACT. Two simple precise and accurate spectrophotometric techniques are developed for simultaneous determination of ternary mixture urea, creatinine, uric acid in humane urine sample. The first technique is a ratio derivative zero - crossing where measured urea at 216.61 nm, creatinine 260.56 283 nm. second successive spectra 203 261 287 respectively. These procedures do not need separation...

We evaluated the effect of frequency and amount of rumen-degradable intake protein (DIP) on urea kinetics in steers consuming prairie hay. Five ruminally and duodenally fistulated steers (366 kg of BW) were used in a 5 x 5 Latin square and provided ad libitum access to low-quality prairie hay (4.7% CP). Casein was provided daily in amounts of 61 and 183 mg of N/kg of BW (61/d and 183/d) and eve...

  Objective(s): Because of the high total phenolic contents of Feijoa sellowiana , its nephroprotective effect was determined in 3,4-methylene dioxymethamphetamine (MDMA) treated mice.   Materials and Methods: Animals received 10, 20 and 40 mg/kg doses of aqueous or methanol extract of F. sellowiana leaves, intra-peritoneally. After one hour, an acute administration of MDMA (20 mg/kg, IP)...

Microdialysis is a technique that enables measurement of extracellular concentrations of unbound analytes. A small probe with a semipermeable membrane is implanted in tissue and constantly perfused. Small analytes in the interstitial fluid diffuse into the perfusate and are collected. Often, microdialysate concentrations of an analyte are only a fraction of the unbound concentrations in the ext...

A method for the simultaneous determination of hypotaurine and taurine was developed. The method consisted of the elimination of urea, which interfered with the determination of hypotaurine, by immobilized urease, and determination of hypotaurine and taurine with an amino acid analyzer. The analyzer equipped with a cation-exchange column was operated at 32 degrees C with 0.2 M sodium citrate bu...
