Nitrogen and lysine utilization efficiencies, protein turnover, and blood urea concentrations in crossbred grower pigs at marginal dietary lysine concentration.

Nitrogen utilization efficiency (NUE) and lysine utilization efficiency (LUE) are key indicators of sustainable pork production and vary depending on nutritional and non-nutritional factors. The objective was to study NUE and LUE together with concentrations of blood urea nitrogen (BUN) and other metabolites in growing pigs fed diets with marginal Lys concentrations at 11-13 wk (40.5 kg mean BW) and 14 to 16 wk (60.

Phytase supplementation effects on amino acid digestibility depend on the protein source in the diet but are not related to InsP degradation in broiler chickens.

The objective was to determine phytase effects on prececal amino acid (AA) digestibility and phytate (InsP) breakdown when different oilseed meals were used in broiler chicken diets. The study included 14 diets: a corn-soybean meal (SBM) basal diet and 6 diets that contained SBM, rapeseed meal (RSM), and sunflower meal (SFM) with 2 inclusion levels at the expense of corn starch (150 and 300 g/kg SBM or SFM, or 100 and 200 g/kg RSM). Each diet was mixed with or without a phytase supplement of 1,500 FTU/kg.

[Quality assurance in specialized palliative home care (QUAPS): a questionnaire's feasibility].

Background: Structure and process parameters are not sufficient for adequate quality assurance in specialized palliative home care (SAPV). Asking the patients and their relatives for their assessment is crucial. A focus group in Jena, Germany, developed the quality assurance in specialized palliative home care (QUAPS) questionnaire for this assessment of outcome parameters, which was tested in two studies.

Regulation of soluble vascular endothelial growth factor receptor (sFlt-1/sVEGFR-1) expression and release in endothelial cells by human follicular fluid and granulosa cells.

Background: During the female reproductive cycle, follicular development and corpus luteum formation crucially depend on the fast generation of new blood vessels. The importance of granulosa cells and follicular fluid in controlling this angiogenesis is still not completely understood. Vascular endothelial growth factor (VEGF) produced by granulosa cells and secreted into the follicular fluid plays an essential role in this process.
