Yuki Enoki教授の研究室は、慢性腎疾患に伴う筋萎縮(サルコペニア)の病態メカニズムを解明することを主眼としています。特に、尿毒性物質であるインドール誘導体(特にインドキシル硫酸)が筋細胞の機能障害やミトコンドリア機能障害を引き起こすメカニズムを解析しており、apelin-Apj系の制御が筋委縮の治療的標的になる可能性を示唆しています。また、抗酸化作用を有する抗生物質の肺疾患に対する応用可能性についても、炎症性活性酸素種の制御という観点から研究を展開しています。

Skeletal muscle atrophy, referred to as sarcopenia, is often observed in chronic kidney disease (CKD) patients, especially in patients who are undergoing hemodialysis. The purpose of this study was to determine whether uremic toxins are involved in CKD-related skeletal muscle atrophy. Among six protein-bound uremic toxins, indole containing compounds, indoxyl sulfate (IS) significantly inhibited proliferation and myotube formation in C2C12 myoblast cells. IS increased the factors related to skel
Our results indicate that IS induces mitochondrial dysfunction in skeletal muscle cells and provides a potential therapeutic strategy such as IS-targeted and mitochondria-targeted interventions for treating CKD-induced muscle atrophy and decreased exercise endurance.
Reactive oxygen species (ROS) and nitric oxide (NO) are major pathogenic molecules produced during viral lung infections, including influenza. While fluoroquinolones are widely used as antimicrobial agents for treating a variety of bacterial infections, including secondary infections associated with the influenza virus, it has been reported that they also function as anti-oxidants against ROS and as a NO regulator. Therefore, we hypothesized that levofloxacin (LVFX), one of the most frequently u
This meta-analysis is the first study that clarifies the usefulness of an alcohol-based CHG solution with a 0.5 per cent or higher CHG concentration for surgical skin preparation to prevent SSI.
This systematic review and meta-analysis compares the efficacy of daptomycin and vancomycin in adult patients with bacteremia by methicillin-resistant Staphylococcus aureus (MRSA) with vancomycin minimum inhibitory concentration (MIC) > 1 µg/mL. We searched the PubMed, Web of Science, Cochrane Library, and ClinicalTrials.gov databases on 12 May 2020. All-cause mortality (primary outcome) and treatment success rates were compared and subgroups stratified by infection source risk level and method
This study demonstrated for the first time the association of the Apj endogenous ligand-uraemic toxin axis with skeletal muscle atrophy in CKD and the utility of therapeutic targeting of the apelin-Apj system.
Prior micafungin use increased the risk of <i>C. parapsilosis</i> and the MIC > 0.06 μg/mL of micafungin in non-<i>parapsilosis Candida</i> species. Since there are only a few antifungal options, further antifungal stewardship considering azole antifungal agents use is required.
• Remdesivir is proposed as a therapeutic for COVID-19 • Clinical improvement after remdesivir was higher compared with placebo • Remdesivir tended to reduce patient mortality rate, but this was not significant
The combined use of daptomycin and statins were significant risk factors for the incidence of CPK elevation defined as levels ≥ULN or ≥5× ULN and rhabdomyolysis.
