Molecular markers for beef tenderness are classic examples of the contribution of genome technology to animal breeding through marker-assisted selection (MAS). Markers on the μ-calpain (CAPN1) and calpastatin (CAST) genes have been extensively evaluated for their association with tenderness. However, little is known about their potential effect on other economically important traits. In this wo...

Fifty-four stores in 30 U.S. cities were sampled from June 2011 through May 2012 to benchmark beef tenderness at retail, as assessed by Warner-Bratzler shear force (WBSF). Top loin (Longissimus dorsi; n = 980) and sirloin (Gluteus medius and Biceps femoris; n = 860) steaks were collected at random (Quality Grade and brand) and shipped via overnight delivery to Colorado State University. From Ju...

The micromolar calcium activated neutral protease (CAPN1) and calpastatin (CAST) have been widely regarded as genes related to muscle growth and meat tenderness. The objective of this study was to verify the association of SNPs of CAPN1 and CAST genes with carcass and tenderness traits and search the possible change patterns of SNPs in CAPN1 and CAST genes in six generations of broiler breeding...

BACKGROUND Cooking has a great influence on meat tenderness, and we assumed that changes of tenderness in this process resulted from the liberation of actin and associated structural changes. Therefore, in this study, we investigated changes in the microstructure and tenderness when duck breast muscle were cooked to different internal endpoint temperatures (70, 80, 90, 95 °C) by three cooking r...

The objective of this study was to determine the relationship of longissimus tenderness classes to tenderness of three other major muscles. Ninety-eight crossbred steers and heifers (14 to 17 mo of age) were humanely slaughtered over 9 wk and the carcasses were chilled 48 h at 0 degrees C. At 48 h postmortem, carcasses were assigned to one of three tenderness classes (tender < or = 26 kg, inter...

Criteria for excluding cervical spine injury in patients who have sustained blunt head or neck trauma were prospectively studied at four hospitals in the Chicago area. The authors attempted to define a subset of these adult patients who, based on clinical criteria, could reliably be excluded from cervical spine radiography, thus avoiding unnecessary radiation and saving considerable time and mo...

abstract background ewing sarcoma is the second most frequent primary bone cancer, following osteosarcoma in children. these tumors consist of small, round, or oval cells, which are believed to derive from parasympathetic autonomic nervous system. the common clinical presentations are pain, local tenderness, fever, palpable mass, and pathologic fractures. methods and materials this study descri...
