Studies have suggested that the phenomenon of dark cutting (Canada B4) beef may also be related to muscle glycolytic proteins. The objective of this study, therefore, was to analyze longissimus thoracis (LT; n=23), from Canada AA (n=8), atypical (AB4; pH<5.9, n=8) and typical (TB4; pH>5.9, n=7) B4 heifer and steer carcasses, for sarcoplasmic and myofibrillar proteins using 2-D gel electrophoresis and LC-MS/MS mass spectrometry. Results indicated that AB4 LT had intramuscular pH and lactate concentration similar to Canada AA but lower (P<0.05) L* and b*. Moreover, AB4 LT were tougher than Canada AA even at 21days post-mortem, unlike TB4. Canada AB4 LT had reduced (P<0.05) levels of creatine kinase, glyceraldehyde-3-phosphate dehydrogenase, lactate dehydrogenase and glycerol-3-phosphate dehydrogenase [NAD(+)], indicating a compromised glycolytic capacity in AB4. Canada AB4 LT had increased (P<0.05) abundances of phosphatidylethanolamine-binding protein 1 and small heat shock proteins.

Statement Of Problem: Infrared radiation heating (IRH) technology has been innovatively applied to the annealing of selective laser melted (SLM) cobalt chromium (Co-Cr) frameworks. However, previous studies have not reported the effects of IRH on the warping deformation and mechanical properties of these frameworks.
Purpose: The purpose of this in vitro study was to investigate the effects of IRH on the warping deformation and mechanical properties of dental SLM Co-Cr alloy and to evaluate its potential applications in dental restorations.

This study aimed to determine the prevalence of carcass bruising in Simmental cross-breed bulls and to characterize the bruises in terms of number, size, shape, severity, and the affected region of the carcass. In addition, the risk factors related to the pre-harvested and harvested phase of beef production and meat quality parameters, as well, were investigated. The prevalence of bruised carcasses was 40.

Article Synopsis
- The development of advanced personal protective equipment (PPE) using functional materials is crucial for preventing the spread of infectious diseases, but achieving effective antimicrobial properties remains a challenge.
- A newly reported hierarchically porous cerium metal-organic framework (Ce-MOF) significantly enhances antimicrobial performance by promoting the generation of reactive oxygen species (ROS) and effectively trapping bacteria.
- This innovative Ce-MOF design provides exceptional antimicrobial efficacy—nearly 100%—even in low-light conditions, paving the way for the creation of self-disinfecting PPE materials.
Aging increases lightness of grass-fed beef.

Grass-fed beef is becoming increasingly popular and is expected to be a $14 billion industry by 2024. Even so, grass-fed beef is typically darker in appearance than that of conventional grain-fed beef. Aging has been shown to improve lean color (*, *) of dark-cutting beef however little work has focused on aging as it relates to improving the lean color of grass-fed beef.

The purpose of this study is to explore the carcass traits, meat quality, and nutritional attributes of local yellow cattle (Guangfeng, Ji'an, and Jinjiang) and buffalo (Poyanghu, Xiajiang, and Xinfeng mountain) in Jiangxi Province, and compare the differences among different breeds. The results showed that the dressing percentage, net meat percentage, and meat-bone ratio of Jinjiang cattle were highest, and that Jinjiang cattle had the best meat production performance. Regarding meat quality, the pH value of all breeds was at normal level, and no dark-cutting beef was produced.
