Association of Head-Neck Rotation With History of Pitching-Related Elbow Pain in Youth Baseball Players.

Background: Prevention of pitching-related elbow pain in youth baseball players is important. Overhead pitching involves a whole-body motion, including head-neck rotation. A limited range of motion of head-neck rotation may cause inefficient pitching motion; however, this association is unclear.

Ultrasonographic prevalence of ulnar nerve displacement at the elbow in young baseball players.

Background: Overhead-throwing athletes are at risk of elbow injury because of valgus stress, leading to unstable ulnar nerves and neuropathy. Studies regarding ulnar nerve damage/displacement have been performed primarily in adults.

Objective: To determine the prevalence and related factors associated with ulnar nerve displacement at the elbow in young baseball players.

Evaluation of Disappearance Time and Palatability of Foams in the Oral Cavities of Healthy Volunteers, and Preparation of Drug-Containing Foam Formulations for Use in the Treatment of Oral Mucositis.

Oral mucositis is one of the most common adverse effects of radiation and chemotherapy in treatments of cancers. Some clinical guidelines have focused on the prevention and treatment of oral mucositis, and thus, a mouthwash containing drugs is often recommended. In this study, we aimed to evaluate the disappearance time and palatability in the oral cavities of healthy volunteers in foams prepared from different concentrations of the three viscosity grades of methylcellulose (SM-4, -100, -400).

Structural and Functional Comparison of Flagellar Filaments Composed of FljB and FliC.

The bacterial flagellum is a motility organelle consisting of a long helical filament as a propeller and a rotary motor that drives rapid filament rotation to produce thrust. serovar Typhimurium has two genes of flagellin, and , for flagellar filament formation and autonomously switches their expression at a frequency of 10-10 per cell per generation. We report here differences in their structures and motility functions under high-viscosity conditions.

Inhibin βE (INHBE) is a possible insulin resistance-associated hepatokine identified by comprehensive gene expression analysis in human liver biopsy samples.

The liver plays a major role in whole-body energy homeostasis by releasing secretory factors, termed hepatokines. To identify novel target genes associated with insulin resistance, we performed a comprehensive analysis of gene expression profiles using a DNA chip method in liver biopsy samples from humans with varying degrees of insulin resistance. Inhibin βE (INHBE) was identified as a novel putative hepatokine with hepatic gene expression that positively correlated with insulin resistance and body mass index in humans.
