Measurements were conducted during trial runs for each unit operation (washing/pealing, rasping, extraction and separation). Starch mass balance was calculated from sample composition (moisture, starch and crude fiber and ash content). Production capacity, water consumption, electric requirements and capital-labor costs were also measured. The manufacturing processes differed mainly on starch recovery from starch present in washed roots (65 vs. 76%), extraction PD0332991 purchase capacity (0.3 vs. 0.9 t of washed roots/h), water consumption (45 vs. 21 m(3)/t of dry starch), energy consumption (59 vs. 55 kWh/t of starch) and production costs (1,156 vs. 162 US$/t of starch) for Colombia and Vietnam, respectively. Moreover, the effectiveness

of the starch extraction process could largely be attributed to the differences in the extent of root disintegration achieved with different rasping

equipment.”
“Ornithine aminotransferase BMS-777607 ic50 (l-ornithine 2-oxoacid aminotransferase, OAT) is widely expressed in organs, but studies in mice have focused primarily on the intestine, kidney and liver because of the high OAT-specific activity in these tissues. This study aimed to investigate OAT activity in adult mouse tissues to assess the potential contribution to ornithine metabolism and to determine OAT control during postnatal development. OAT activity was widely distributed in mouse tissues. Sexual dimorphism was observed for most tissues in adults, with greater activity in females than in males. The contribution of skeletal muscles to total OAT this website activity (34 % in males and 27 % in females) was the greatest (50 %) of the investigated tissues in pre-weaned mice and was similar to that of the liver in adults. OAT activity was found to be regulated in a tissue-specific manner during postnatal development in parallel with large changes in the plasma testosterone and corticosterone levels. After weaning, OAT activity markedly increased in the liver but dropped in the skeletal muscle and adipose tissue. Anticipating weaning

for 3 days led to an earlier reduction of OAT activity in skeletal muscles. Orchidectomy in adults decreased OAT activity in the liver but increased it in skeletal muscle and adipose tissue. We concluded that the contribution of skeletal muscle to mouse ornithine metabolism may have been underestimated. The regulation of OAT in skeletal muscles differs from that in the liver. The present findings suggest important and tissue-specific metabolic roles for OAT during postnatal development in mice.”
“The hydrogen bond network leading from bulk water to the trinuclear copper center in bilirubin oxidase is constructed with Glu463 and water molecules to transport protons for the four-electron reduction of dioxygen. Substitutions of Glu463 with Gln or Ala were attributed to virtually complete loss or significant reduction in enzymatic activities due to an inhibition of the proton transfer steps to dioxygen.
