Variation in hydration status within the normative range is associated with urinary biomarkers of systemic oxidative stress in Guatemalan preschool children.

Background: Researchers have increasingly sought noninvasive methods to determine health and nutritional status in humans. Easy and painless to collect, human urine is a source of noninvasive biomarkers.

Objective: We aimed to explore the relation between systemic oxidative stress biomarkers excreted in urine and urinary osmolality (Uosm).

Efficient analysis of egg yolk proteins and their thermal sensitivity using sodium dodecyl sulfate polyacrylamide gel electrophoresis under reducing and nonreducing conditions.

The multiple functional properties of egg yolk are mostly influenced by its complex protein composition. The high lipid content of egg yolk as well as the low solubility of delipidated egg yolk lipoproteins make analysis by conventional chromatographic or electrophoretic techniques a difficult task. This work describes a method to profile egg yolk proteins after delipidation with acetone using sodium dodecyl sulfate polyacrylamide gel electrophoresis on precast 8-18% T polyacrylamide gradient gels.

Microbes in food processing technology.

There is an increasing understanding that the microbial quality of a certain food is the result of a chain of events. It is clear that the microbial safety of food can only be guaranteed when the overall processing, including the production of raw materials, distribution and handling by the consumer are taken into consideration. Therefore, the microbiological quality assurance of foods is not only a matter of control, but also of a careful design of the total process chain.

Infraglomerular Epithelial Reflux as a Postmortem Phenomenon in the Kidneys of Dog and Rat.

The significance of postmortem renal changes for the pathogenesis of infraglomerular epithelial reflux (IER) was examined in a number of experiments with kidneys of the dog and rat. The reflux can develop after death in both species. Intravital circumstances (e.
