one of the main constraints in aloe vera production is poor information about optimum nutrients that are helpful for growth and production. the objective of this study was to optimize nutrient solution for aloe vera cultivation in soilless culture. therefore, to determine the best nutrients the experiment was conducted in a greenhouse during 2011 in the agricultural faculty, university of guila...

Variation in human taste is a well-known phenomenon. However, little is known about the molecular basis for it. Bitter taste in humans is believed to be mediated by a family of 25 G protein-coupled receptors (hT2Rs, or TAS2Rs). Despite recent progress in the functional expression of hT2Rs in vitro, up until now, hT2R38, a receptor for phenylthiocarbamide (PTC), was the only gene directly linked...

As diseases caused by solar radiation have gained great prominence, several methods to prevent them been developed. Among the most common, use of sunscreens is customary and accessible. The application theoretical has helped design new compounds with therapeutic protective functions. Natural described photoprotective potential properties (3-O-methylquercetin, gallic acid, aloin, catechin, querc...
