Exploring Throwing Yips in Youth Baseball Players: Prevalence, Symptoms, Players' Psychological Characteristics, and Triggers.

Symptoms of "the yips" manifest in various sports and often cause athletes to retire prematurely from competition. While there have been case studies on yips-affected baseballers (YBBs), there has been no comprehensive demographic profile of YBBs, and contributing factors are only partially understood. We aimed to describe youth YBBs' demographic characteristics and explore contributing factors to yips symptoms.

Impact of advanced footwear technology for Japanese Ekiden athletes.

Background: Advanced footwear technology (AFT) was developed with the goal of running a marathon in under 2 hours. This pace (2:51 min/km) is similar to the race pace of Ekiden, which are road relays where each athlete covers a distance ranging from 15 kilometers to 22 kilometers. This study aimed to elucidate the impact of AFT on the records of Japanese Ekiden runners.

Antibacterial Dental Adhesive Containing Cetylpyridinium Chloride Montmorillonite.

Oral bacteria cause tooth caries and periodontal disease. Much research is being conducted to prevent both major oral diseases by rendering dental materials' antimicrobial potential. However, such antimicrobial materials are regarded as 'combination' products and face high hurdles for regulatory approval.

Long-Term Bonding Performance of One-Bottle vs. Two-Bottle Bonding Agents to Lithium Disilicate Ceramics.

The aim of this study was to compare the long-term bonding performance to lithium disilicate (LDS) ceramic between one-bottle and two-bottle bonding agents. Bonding performance was investigated under these LDS pretreatment conditions: with hydrofluoric acid (HF) only, without HF, with a two-bottle bonding agent (Tokuyama Universal Bond II) only. Shear bond strengths between LDS and nine resin cements (both self-adhesive and conventional adhesive types) were measured at three time periods: after one-day water storage (Base), and after 5000 and 20,000 thermocycles (TC 5k and TC 20k respectively).

Activation of Mitochondria in Mesenchymal Stem Cells by Mitochondrial Delivery of Coenzyme Q.

The efficacy of mesenchymal stem cell (MSC) transplantation has been reported for various diseases. We previously developed a drug delivery system targeting mitochondria (MITO-Porter) by using a microfluidic device to encapsulate Coenzyme Q (CoQ) on a large scale. The current study aimed to confirm if treatment with CoQ encapsulated by MITO-Porter enhanced mitochondrial functions in MSCs, with the potential to improve MSC transplantation therapy.
