Extract Induces Apoptosis in Human Pancreatic 3D Cancer Models: Importance of Major Antioxidant Molecules Present Therein.

In recent years, interest in L. has been rising, as legislation is moving in the right direction. This plant has been known and used for thousands of years for its many active ingredients that lead to various therapeutic effects (pain management, anti-inflammatory, antioxidant, etc.

Effects of increasing alfalfa (Medicago sativa) leaf levels on the fattening and slaughtering performance of organic broilers.

A feeding trial was conducted to evaluate the effects of increasing alfalfa leaf levels on the performance of organic broilers. The impact of drying temperature on the nutritional value of alfalfa leaves and thereby on broiler performance was studied using alfalfa leaves dried at either low (alfalfa leaves low temperature (ALLT)) or high temperatures (alfalfa leaves (AL)). Six hundred male Hubbard JA-757 broilers were divided into five feeding groups (Control (C), AL2, AL3, AL4 and ALLT5).

Effects of processing steps on the phenolic content and antioxidant activity of beer.

A new analytical method (liquid chromatography-antioxidant, LC-AOx) was used that is intended to separate beer polyphenols and to determine the potential antioxidant activity of these constituents after they were allowed to react online with a buffered solution of the radical cation 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS(•+)). Using the LC-AOx method, it was possible to demonstrate that the extent of the antioxidant activity was very much dependent on the phenolic compound considered. The method was also applied to the analysis of beer extracts and allowed the evaluation of their antioxidant activity at different steps of beer processing: brewing, boiling, and fermentation.

Predicting the substrate specificity of a glycosyltransferase implicated in the production of phenolic volatiles in tomato fruit.

The volatile compounds that constitute the fruit aroma of ripe tomato (Solanum lycopersicum) are often sequestered in glycosylated form. A homology-based screen was used to identify the gene SlUGT5, which is a member of UDP-glycosyltransferase 72 family and shows specificity towards a range of substrates, including flavonoid, flavanols, hydroquinone, xenobiotics and chlorinated pollutants. SlUGT5 was shown to be expressed primarily in ripening fruit and flowers, and mapped to chromosome I in a region containing a QTL that affected the content of guaiacol and eugenol in tomato crosses.
