Enhancing gene transfer to renal tubules and podocytes by context-dependent selection of AAV capsids.

AAV vectors show promise for gene therapy; however, kidney gene transfer remains challenging. Here we conduct a barcode-seq-based comparison of 47 AAV capsids administered through different routes in mice, followed by individual validation. We find that local delivery of AAV-KP1, but not AAV9, via the renal vein or pelvis effectively transduces proximal tubules with minimal off-target liver transduction, while systemic AAV9, but not AAV-KP1, enhances proximal tubule and podocyte transduction in chronic kidney disease.

Orally administrated acetate inhibits atherosclerosis progression through AMPK activation via GPR43 in plaque macrophages.

Background And Aims: Oral administration of acetic acid, a short-chain fatty acid, has been shown to efficiently reduce obesity and insulin resistance in both experimental animals and humans. The anti-atherosclerotic effect of acetate is expected owing to its anti-inflammatory and anti-oxidative stress characteristics; however, this remains to be fully understood.

Methods: For 12 weeks, apolipoprotein E-deficient mice were administered 0.

Essential oil components of turmeric inhibit hepatic lipidification and liver fibrosis in a diet-induced NASH model rats.

In this study, the fraction extracted from turmeric powder with 50% ethanol and fractionated with n-hexane were administered to diet-induced NASH model rats. NASH model was prepared with SD rats by feeding an originally designed choline-deficient, high-fat, high-fructose (HFF-CD) diet for 10 weeks. To the HFF-CD diet, hexane fraction and 50% ethanol fraction after hexane fractionation were added at 100 mg/kg body weight.

Reliability in viscosity measurement of thickening agents for dysphagia management: Are results obtained by cone-and-plate rheometers reproducible between laboratories?

Viscosity measurement using a cone-and-plate rheometer is considered to provide an objective and reliable evaluation of thickening agents for dysphagia management. Here, we showed its measurement uncertainty in the context of an inter-laboratory study. Eight test samples (i.
