Is decreased psoas volume a risk factor for hip fracture? A comparative study of patients with and without hip fractures using the exact matching technique.

Introduction: Sarcopenia is linked to increased fall and hip fracture risk. However, studies often overlook comprehensively controlling for age, sex, bone mineral density (BMD), and body mass index (BMI). Our study aimed to determine if sarcopenia, determined by evaluating the psoas muscle volume, is an independent risk factor for hip fractures.

Sirtuin 6 Overexpression Improves Rotator Cuff Tendon-to-Bone Healing in the Aged.

Aging is an independent risk factor for recurrent tearing after surgical repair of rotator cuff ruptures around the tendon-to-bone area. However, aging signature factors and related mechanisms involved in the healing of the rotator cuff are still unknown. We hypothesized that differences in proteins involved in the rotator cuff according to age may affect tendon-to-bone healing.

Bean Extract-Based Gargle for Efficient Diagnosis of Active COVID-19 Infection Using Rapid Antigen Tests.

The antigen-based rapid diagnostic test (Ag-RDT) using saliva specimens is fast, noninvasive, and suitable for SARS-CoV-2 self-testing, unlike nasopharyngeal swab (NPS) testing. We evaluated a novel Beanguard gargle (BG)-based virus collection method that can be applied to Ag-RDT as an alternative to the current RT-PCR with an NPS for early diagnosis of COVID-19. This clinical trial comprised 102 COVID-19-positive patients hospitalized after a governmental screening process and 100 healthy individuals.

A novel assessment of nefazodone-induced hERG inhibition by electrophysiological and stereochemical method.

Nefazodone was used widely as an antidepressant until it was withdrawn from the U.S. market in 2004 due to hepatotoxicity.

Synthesis of LipidGreen2 and its application in lipid and fatty liver imaging.

We have developed LipidGreen2, a second generation small molecule probe for lipid imaging. LipidGreen2 has a better fluorescence signal compared with the previous LipidGreen, and selectively stains neutral lipids in cells and fat deposits in live zebrafish. We also demonstrate the application of LipidGreen2 for detecting fatty liver.

Metabolic profiling of an alcoholic fatty liver in zebrafish (Danio rerio).

Zebrafish (Danio rerio) is becoming a popular developmental biology model to study diseases and for drug discovery. In this study, we performed proton nuclear magnetic resonance spectroscopy ((1)H-NMR)- and gas chromatography-mass spectrometry (GC/MS)-based metabolic profiling of an alcoholic fatty liver using a zebrafish disease model. We examined metabolic differences between the control and alcoholic fatty liver groups in zebrafish to determine how metabolism in an alcoholic fatty liver is regulated.

Molecular characterization, immune responses and DNA protection activity of rock bream (Oplegnathus fasciatus), peroxiredoxin 6 (Prx6).

In this study, we describe the molecular characterization, immune responses of rock bream, Oplegnathus fasciatus peroxiredoxin 6 cDNA (RbPrx6) and DNA protection activity of its recombinant protein. The full-length cDNA sequence of RbPrx6 was identified after pyrosequencing of rock bream cDNA library. RbPrx6 consists of 663 bp open reading frame (ORF) that codes for a putative protein of 221 amino acids with predicted molecular mass of 27 kDa.

Anti-obesity effects of a mixture of thiamin, arginine, caffeine, and citric acid in non-insulin dependent diabetic KK mice.

Anti-obesity effects of a mixture of thiamin, arginine, caffeine, and citric acid (TACC) were investigated in non-insulin dependent diabetic KK mice. Feeding of either arginine or caffeine significantly suppressed an increase in hepatic lipid contents in fasted-refed KK mice. In addition, each component admixed with a low-calorie diet effectively reduced adipose tissue weight in KK mice previously fed a high-calorie diet.
