Inclusive curvaturelike framework for describing dissipation: Metriplectic 4-bracket dynamics.

An inclusive framework for joined Hamiltonian and dissipative dynamical systems that are thermodynamically consistent, i.e., preserve energy and produce entropy, is given.

miRNA-dysregulation associated with tenderness variation induced by acute stress in Angus cattle.

miRNAs are a class of small, single-stranded, non-coding RNAs that perform post-transcriptional repression of target genes by binding to 3' untranslated regions. Research has found that miRNAs involved in the regulation of many metabolic processes. Here we uncovered that the beef quality of Angus cattle sharply diversified after acute stress.

Functional genomic analysis of variation on beef tenderness induced by acute stress in angus cattle.

Beef is one of the leading sources of protein, B vitamins, iron, and zinc in human food. Beef palatability is based on three general criteria: tenderness, juiciness, and flavor, of which tenderness is thought to be the most important factor. In this study, we found that beef tenderness, measured by the Warner-Bratzler shear force (WBSF), was dramatically increased by acute stress.

Primary cultured human breast epithelial cells up-regulate protein disulfide isomerase in response to zeranol.

Background: Experimental data at the molecular, cellular and organismal levels have implicated dietary components in cancer. Exposure to numerous growth factors, hormones and environmental agents, that can regulate signaling events, is involved in carcinogenesis. Research targets on gene-nutrient interactions may give useful information for the development of a novel diet-based intervention for the at-risk population.

Turkey breast meat functionality differences among turkeys selected for body weight and/or breast yield.

Functional meat characteristics were studied in three turkey lines, (1) RBC2: representing 1960s commercial turkeys, (2) F-line: a line selected for body weight (BW) and (3) C-line: a fast growing commercial line with enhanced breast muscle yield. The RBC2s Warner-Bratzler shear force values for the Pectoralis major (PM) were lower than the F- and C-lines' values (P<0.05).
