We studied the osmoregulatory responses of the granivore Zonotrichia capensis, acclimated to highand lowprotein diets as well as two levels of water intake. We tested whether Z. capensis has the ability to modify the proportion of nitrogenous waste in the excreta when protein intake and water intake varies. After 21 days of acclimation, plasma osmolality was not significantly affected by dietar...

This study evaluated the suitability of canola oil as a source of supplemental dietary lipid for rainbow trout. Triplicate groups of the 30 fingerlings held under identical culture conditions were fed twice daily by iso-nitrogenous, iso-calorific and iso-lipidic diets for eight weeks. Experimental diets consisted of 30.3% protein, 18.7 kJg-1 energy and 16.7% lipid from fish oil (FO), canola oil...

Fermented African oil bean (Pentaclethra macrophylla Benth) seed is a successful and well studied seasoning and snack in parts of Western Africa. GC-MS analysis of fermenting seeds revealed a mixture of several volatile aroma compounds which changed with time and starter organism. During natural mixed culture process 36 volatile compounds including 12 hydrocarbons, 10 esters, 5 alcohols, 2 phen...

Abstract The photo-excited triplet state of Zn-protoporphyrin IX located in the heme pocket human neuroglobin has been investigated by time-resolved EPR coupled to magnetophotoselection. protein matrix compared with model complex organic glass, considering both non-coordinating and coordinating solvent mixtures. plays an important role stabilizing coordination embedded chromophore, resulting a ...

Pollution by nitrogenous compounds is a putative stressful factor that may be causally linked to the decline of amphibians. One way to understand the potentially detrimental consequences of eutrophication on amphibian populations is to investigate variation among populations differing in exposure to nitrogen, this variation potentially indicating evolutionary potential to cope with this stresso...

This study investigated the optimal yeast strains for producing single cell protein based on waste sugar beet pulp (SBP) under various biomass loads. All tested were capable of growing biomass. Candida utilis and Saccharomyces cerevisiae Ethanol Red produced greatest increase in fresh SBP (ΔN 1.84%). Scheffersomyces stipitis 2.27%) provided highest dried SBP. showed significant assimilation nit...

Three forms of recombinant protein complexes comprising the human prorenin (hPro) and (pro)renin receptor (hPRR) (hPRR/prorenin) were successfully expressed in the silkworm larvae using Bombyx mori nucleopolyhedrovirus (BmNPV) bacmids. They were localized in the fat body cells and formed a prorenin-bound hPRR complex. The expressed levels of hPro and hPRR were similar judging from Western blott...

Urea is the major nitrogenous end product of protein metabolism in mammals. Here, we describe a quantitative, sensitive method for urea determination using a modified Jung reagent. This assay is specific for urea and is unaffected by ammonia, a common interferent in tissue and cell cultures. We demonstrate that this convenient colorimetric microplate-based, room temperature assay can be applied...
