Bone regeneration-enhancing effects of extremely low-frequency electromag- netic fields: Analysis using fish scales as a bone model.

Electromagnetic fields (EMFs) noninvasively promote fracture healing, prevent osteoporosis, promote diaphyseal growth, enhance differentiation, and stimulate cell division. However, no good model systems for analyzing bone regeneration have been reported. In this study, we examined the in vivo regeneration of scales having osteoblasts and osteoclasts using a new magnetic field generator for exposing aquatic animals to EMFs at a sine-wave frequency of 60 Hz.

Low attenuation areas in necrotizing soft tissue infection.

Necrotizing Soft Tissue Infection can be challenging to differentiate from abscesses based on computed tomography imaging findings only, so it is crucial to perform surgical debridement as early as possible.

Refractory gastric ulcer due to undisclosed use of topical diclofenac epolamine patches.

Background: Topical forms of nonsteroidal anti-inflammatory drugs (NSAIDs) have been created to lessen systemic adverse effects. In general, they are believed to be well tolerated and appropriate for use as an over-the-counter (OTC) drug.

Case Presentation: A 68-year-old woman visited our clinic due to tarry stool.

A biomechanics analysis of the judo osoto-gari technique: comparison of black belt and white belt judokas.

The purpose of this study was to determine biomechanical factors for the effective execution of the osoto-gari technique by comparing differences between black belt and white belt judokas. Twenty-two male judokas (12 black belts; 10 white belts) performed osoto-gari, and the motion data were recorded using a Mac3D motion analysis system (250 Hz). The peak angular momentums of the trunk and leg of the uke were larger in the black belts than in the white belts, suggesting that the black belts rotated the uke's body more effectively than the white belts.
