to evaluate the effect of roasting and dutching processes on the stability of b-aflatoxins (afb1+afb2), experimental units of cocoa beans contaminated with aflatoxin at a concentration of 220.7 ng g-1 were roasted at 250ºc for 15 minutes. roasting conditions caused a notable reduction in the aflatoxin content (up to 71%). the resulting cocoa liquors contaminated with 63.9 ng g-1 were thermal-al...

The midgut of larval lepidopteran insects rapidly raises the pH of the entering food from approximately neutral values to as high as pH 12 in some species (Waterhouse, 1949; Dow, 1984). These values are among the highest achieved by biological systems and are all the more remarkable in view of the high rate of food consumption relative to body mass in lepidopteran larvae. The isolated midgut of...

To fully understand the glycolytic behavior of cancer cells, it is important to recognize how it is linked to pH dynamics. Here, we evaluated the acute effects of mild acidification and alkalization on cancer cell glucose uptake and glycolytic flux and investigated the role of hexokinase (HK). Cancer cells exposed to buffers with graded pH were measured for 18F-fluorodeoxyglucose (FDG) uptake, ...

Catch is a holding state of muscle where tension is maintained passively for long time periods in the absence of stimulation. The catch state becomes obvious after termination of activation; however, it is possible that catch linkages are already established during activation. To investigate this, skinned fibre bundles of the anterior byssus retractor muscle of Mytilus edulis were maximally act...

Increasing global concern to environmental issues and sustainability related preservation of non-renewable natural resources has encouraged research develop new friendly materials products based on renewable resources. Sorghum fiber potential be a composite reinforcement because it good mechanical properties, inexpensive. The preparation process sorghum is needed improve its compatibility with ...

Abnormalities in systemic acid-base balance may induce significant changes in the immune response, and they may play a significant role in the development or maintenance of immune dysfunction. Different forms of acidosis (metabolic and respiratory) and even different types of metabolic acidosis (hyperchloremic and lactic) may produce different effects on immune function. If alkalization has, or...
