Sarcopenia, loss of muscle mass and function, is mainly observed in elderly people. In this study, we investigated whether fermented rice germ extract (FRGE) has some effects on the mouse gastrocnemius muscle by using behavioral and morphological analyses, Western blotting, and a murine model of immobilization-induced muscle atrophy. Daily oral FRGE administration increased muscle weight and strength. In addition, myofiber size in gastrocnemius muscle of FRGE-treated mice was increased as revealed by morphological quantification. Activation of AMP-activated protein kinase (AMPK) signaling, which inhibits protein synthesis and stimulates protein degradation in gastrocnemius muscle, was significantly attenuated in the FRGE-treated mice compared with control mice. Expression level of forkhead box 3a (FOXO3a) protein was also significantly decreased in the FRGE-treated group. Moreover, the decrease in mean myofiber cross-sectional area in immobilized hindlimb in vehicle-treated mice was inhibited by FRGE treatment in histological analysis. In conclusion, FRGE increased the strength and weight of gastrocnemius muscle and myofiber size, and reduced immobilization-induced muscle atrophy in mice. These findings indicated that FRGE might be beneficial in preventing motor dysfunction in a range of conditions, including sarcopenia.

In this experiment, gene actions were analysized for seven barley parents in order to obtain basic information on their genetic improvement by diallel crosses. The results obtained were summarized as follows. In analysis of variance, additive, dominant, maternal and reciprocal effects were observed significantly for culm length, tiller number, number of spiked per plant, culm diameter, awn length, leaf width, number of grains per spike, and 1000 grain weight. Over-dominance was shown by Vr-Wr graphic analysis in five characters such as tiller number, number of spikes per plant, length of flag leaf, number of grains per spike, and 1000 grain weight, and partial dominance in four characters such as culm length, culm diameter, awn length, and leaf width. Component of genetic varience analyzed for four characters such as culm diameter, awn length, length of flag leaf, and leaf width showed that additive effects were higher than dominant effects. Culm length, tiller number, number of spikes per plant, number of grains per spike, and 1000 grain weight showed dominant effects higher than additive effects. The narrow-sense heritability for awn length, leaf width, and number of grains per spike showed high values as more than 0.62, while broad-sense heritability for culm length, number of spikes per plant, culm diameter, awn length, leaf width, number of grains per spike, and 1000 grain weight showed high values as more than 0.65.

Background/Aims: Multiple white and flat elevated lesions (MWFL) that develop from the gastric corpus to the fornix may be strongly associated with oral antacid intake. Therefore, this study aimed to determine the association between the occurrence of MWFL and oral proton pump inhibitor (PPI) intake and clarify the endoscopic and clinicopathological characteristics of MWFL. Methods: The study included 163 patients. The history of oral drug intake was collected, and serum gastrin levels and anti-Helicobacter pylori immunoglobulin G antibody titers were measured. Upper gastrointestinal endoscopy was performed. The primary study endpoint was the association between MWFL and oral PPI intake. Results: In the univariate analyses, MWFL were observed in 35 (49.3%) of 71 patients who received oral PPIs and 10 (10.9%) of 92 patients who did not receive oral PPIs. The occurrence of MWFL was significantly higher among patients who received PPIs than in those who did not (p<0.001). Moreover, the occurrence of MWFL was significantly higher in patients with hypergastrinemia (p=0.005). In the multivariate analyses, oral PPI intake was the only significant independent factor associated with the presence of MWFL (p=0.001; odds ratio, 5.78; 95% confidence interval, 2.06–16.2). Conclusions: Our findings suggest that oral PPI intake is associated with the presence of MWFL (UMINCTR 000030144).
