Effect of Milk Origin and Seasonality of Yogurt Acid Whey on Antioxidant Activity before and after In Vitro Gastrointestinal Digestion.

Yogurt acid whey (YAW) is a by-product of Greek strained yogurt production. The disposal of YAW constitutes an environmental problem, and given the increasing demand of Greek yogurt worldwide, its handling is a challenge. However, whey-derived peptides, resulting from microbial fermentation as well as those resulting from further hydrolysis during the digestion process, have been linked to enhanced biological activities.

In vitro evaluation of the effect of yogurt acid whey fractions on iron bioavailability.

A side effect of the raised consumption of Greek yogurt is the generation of massive amounts of yogurt acid whey (YAW). The dairy industry has tried several methods for handling these quantities, which constitute an environmental problem. Although the protein content of YAW is relatively low, given the huge amounts of produced YAW, the final protein amount in the produced YAW should not be underestimated.

Genomic distribution and polymorphism of G-quadruplex motifs occupying ovine promoters and enhancers.

G-quadruplexes are non-canonical DNA structures that are formed in regions with short runs of guanines. During the last decade they have gained considerable attention due to their involvement in basic cellular processes, linking them to several physiological processes and pathological conditions. Regulation of gene transcription is among the crucial roles that G-quadruplexes play in the cells.

Genomic landscape, polymorphism and possible LINE-associated delivery of G-quadruplex motifs in the bovine genes.

G-Quadruplex structures are non-B DNA structures that occur in regions carrying short runs of guanines. They are implicated in several biological processes including transcription, translation, replication and telomere maintenance as well as in several pathological conditions like cancer and thus have gained the attention of the scientific community. The rise of the -omics era significantly affected the G-quadruplex research and the genome-wide characterization of G-Quadruplexes has been rendered a necessary first step towards applying genomics approaches for their study.
