Understanding of biological impact of proteome profile on meat quality is vital for developing different approaches to improve meat quality. Present study was conducted to unravel the differences in biochemical, ultrastructural and proteome profile of longissimus dorsi muscle between buffaloes (Bubalus bubalis) of different age groups (young v. old). Higher (P<0.05) myofibrillar and total protein extractability, muscle fibre diameter, and Warner-Bratzler shear force (WBSF) values was observed in old buffalo meat relative to meat from young buffaloes. Scanning electron microscopy photographs revealed reduced fibre size with increased inter-myofibrillar space in young compared with old buffalo meat. Transmission electron microscopy results revealed longer sarcomeres in young buffalo meat relative to meat from old buffaloes. Proteomic characterization using two-dimensional gel electrophoresis (2DE) found 93 differentially expressed proteins between old and young buffalo meat. Proteome analysis using 2DE revealed 191 and 95 differentially expressed protein spots after 6 days of ageing in young and old buffalo meat, respectively. The matrix assisted laser desorption ionization time-of flight/time-of flight mass spectrometry (MALDI-TOF/TOF MS) analysis of selected gel spots helped in identifying molecular markers of tenderness mainly consisting of structural proteins. Protein biomarkers identified in the present study have the potential to differentiate meat from young and old buffaloes and pave the way for optimizing strategies for improved buffalo meat quality. © The Animal Consortium 2016.

Momordica charantia or Bitter Melon, a tropical vegetable, is a common food in Indian cuisine and has been used extensively in folk medicine as a remedy for diabetes. The present study was undertaken to evaluate the hypoglycemic effect of Momordica charantia extract in streptozotocin-induced diabetic rat model for a period of 45 days. The alcoholic extract of Momordica charantia was administered orally at the dose rate of 100 and 200 mg/kg body weight in distilled water and compared with standard oral hypoglycemic drug, glibenclamide. In the study a significant (P≤ 0.001) improvement in the physiological and biochemical parameters such as body weight, hemoglobin concentration, serum glucose, cholesterol and triglyceride levels was observed in Momordica charantia treated rats as compared to diabetic control rats. In Momordica charantia treated rats there was gradual and progressive alleviation of streptozotocin effects with M. charantia at higher dose rate (200 mg per kg body weight), more effective in normalizing the pancreatic endocrinal architecture, improving the number of β-cells and in enhancing the insulin secretion. Immunohistochemistry and special staining revealed improvement in the insulin secretion in Momordica charantia and glibenclamide treated groups.

A "two-step" aptamer-based surface-enhanced Raman scattering (SERS) detection assay was developed for ricin in liquid foods. Ricin B chain was first captured out of food matrices by aptamer-conjugated silver dendrites and then the spectrum was directly read on the silver dendrites. Aptamer use in this assay promotes ease of manipulation as well as improved sensitivity compared to antibody-based approaches. The limit of detection for ricin B chain was 10 ng mL-1 in phosphate buffered saline (PBS), 50 ng mL -1 in orange juice, and 100 ng mL-1 in milk based on principal component analysis (PCA) of measured spectra. This assay shows great promise as a rapid (< 40 min), sensitive, and simple "Yes/No" method to detect bio-weapons like ricin in liquid foods. © The Royal Society of Chemistry 2011.

Augmenting the meat production is among the primary breeding objective of genetic selection programs in poultry production. However, the knowledge about the expression of genes regulating muscle growth at the molecular level is inadequate. Activin type IIB receptor (ACTRIIB) has been reported to play vital role in the negative regulation of muscle growth by binding to multiple members of transforming growth factor-β superfamily. The present investigation was carried out to comprehend the trend of ACTRIIB messenger RNA in pectoralis major muscle during embryonic (E5-20) and post embryonic age (days 1, 14, 28, and 42) in both Control Broiler (CB) and Aseel by using Real-time PCR. The expression profile of ACTRIIB gene displayed a similar trend in CB and Aseel, however Aseel showed significantly (P < 0.001) higher transcription throughout the period. The fold change in expression of ACTRIIB in Aseel relative to CB varied from 3.94 to 14.72 folds and 3.28 to 7.14 folds during embryonic and post embryonic age, respectively. ACTRIIB exhibited its peak on E7, E11, and E16 during embryonic age, which coincides with the formation of primary and secondary muscle fibers in both lines. While at the time of post-embryonic age, ACTRIIB showed highest transcription on day 1 and lowest transcription on day 28 in both CB and Aseel. Within each line, the expression of ACTRIIB differed significantly (P < 0.001) between days in the course of embryonic and post-embryonic period. ACTRIIB gene expression had significant (P < 0.05) effect on all carcass traits except neck weight. Our results suggest that Aseel expressed higher levels of ACTRIIB transcript than CB. The study inferred that expression pattern of ACTRIIB was analogous in both CB and Aseel, which might imply that molecular mechanisms underlying muscle development and regulation are comparable in nature. 2016 Copyright © Taylor & Francis Group, LLC
