Objective: This study investigated the meat quality characteristics, endogenous proteolytic enzymes, collagen content, and myosin heavy chain (MyHC) isoforms of different muscles of Thai native cattle (TNC). Methods: Infraspinatus (IF), Longissimus thoracis (LT), and Supraspinatus (SS) muscles were obtained from two TNC breeds, Kho-Lan (KL, n = 7) and Kho-Isaan (KI, n = 7). The muscle and meat characteristics of TNC breeds and their relationship with MyHC expression were examined. Results: Three MyHC isoforms namely MyHC I, MyHC IIa, and MyHC IIx were detected in the muscles. The KL had higher (p<0.05) MyHC IIx than the KI. The IF muscle had higher (p<0.05) MyHC I compared to other muscles. The LT muscle had the least MyHC I. The LT had higher (p<0.05) MyHC IIx than the IF and SS muscles. The IF presented the least MyHC IIx. The KL had higher (p<0.05) lightness and moisture content and lower crude protein, redness, cooking loss, shear force, and calpastatin than the KI. The glycogen, total collagen, soluble collagen, crude protein, ash contents, and troponin T degradation product of IF and SS were lower (p<0.05) than that of LT. Ether extract in LT was lower (p<0.05) than that of IF and SS. The percentage of MyHC I, MyHC IIa, and MyHC IIx were significantly correlated with muscle and meat characteristics of TNC. Conclusion: These results suggest that the differences in the MyHC isoforms may partly account for the variation in meat quality between breeds and among muscles of TNC.

Background: Idiopathic pulmonary fibrosis (IPF) is a progressive disease often accompanied by skeletal muscle wasting. We aimed to assess whether skeletal muscle mass and muscle attenuation on computed tomography (CT) are predictors of mortality in IPF patients using a nationwide cloud-based database and web-based multidisciplinary discussion (MDD) system. Methods: IPF patients diagnosed using MDD from April 2009 to March 2014 were included. We analyzed the cross-sectional area (CSA) of the erector spinae muscle (ESM<sub>CSA</sub>) and the pectoralis muscle (PM<sub>CSA</sub>), muscle attenuation of ESM (ESM<sub>MA</sub>), and PM (PM<sub>MA</sub>) on single-slice axial CT. Survival probability was assessed by the Kaplan-Meier method and compared by the log-rank test. Multivariate Cox proportional hazards models were performed to evaluate the relationship among the ESM<sub>CSA</sub>, PM<sub>CSA</sub>, ESM<sub>MA</sub>, PM<sub>MA</sub>, clinical parameters, and prognosis. Results: A total of 199 IPF patients were enrolled. Seventy-four patients died during the study period and the most frequent cause was acute exacerbation (13.1%). The group with the lowest quartile of ESMCSA had significantly worse survival than other groups (P = 0.009). Survival rates of the groups with the lowest quartile of PM<sub>CSA</sub>, lower ESM<sub>MA</sub>, and lower PM<sub>MA</sub> were not different from other groups. After multivariate analysis, ESM<sub>CSA</sub> < lower quartile was significantly associated with all-cause mortality (hazards ratio, 1.96; P = 0.030), whereas, ESM<sub>MA</sub> < median, PM<sub>CSA</sub> < lower quartile, and PM<sub>MA</sub> < median were not. Conclusions: Low ESM<sub>CSA</sub> on CT images may be a strong risk factor for all-cause mortality in IPF patients nationwide by MDD diagnosis.
