Hyperglycemia is a risk factor for sarcopenia when comparing individuals with and without diabetes. However, no studies have investigated whether the findings could be extrapolated to patients diabetes relatively higher glycemic levels. Here, we aimed clarify control was associated in type 2 diabetes.Study participants consisted of (n = 746, average age 69.9 years) an older general population 2,067, 68.2 years). Sarcopenia defined as weak grip strength or slow usual gait speed low skeletal...

Abstract Aims/Introduction It is unclear how changes in body composition induced by sodium–glucose cotransporter 2 ( SGLT 2) inhibitor treatment correlate with metabolic profile changes. We aimed to clarify component changes, and if causes sarcopenia bone mineral content BMC ) loss. Materials Methods Moderately obese Japanese type diabetes patients, treated luseogliflozin for a year, were observed prospectively evaluated analyzed the individual components during treatment, their correlation...

The Soft X-ray Imager (SXI) is the charge-coupled device (CCD) camera for soft imaging telescope Xtend installed on Imaging and Spectroscopy Mission (XRISM), which was adopted as a recovery mission Hitomi satellite successfully launched 2023 September 7 (JST). In order to maximize science output of XRISM, we set requirements find that CCD employed in Hitomi/SXI or similar, i.e., $2 \times 2$ array back-illuminated CCDs with $200~\mu$m-thick depletion layer, would be practically best among...

Blood flow regulation in pancreatic islets is critical for function but poorly understood. Here, we establish an vivo imaging platform a non-human primate where transplanted autologously into the anterior chamber of eye are monitored non-invasively and longitudinally at single-cell resolution. Engrafted were vascularized innervated maintained cytoarchitecture situ pancreas. velocity engrafted was not affected by increasing blood glucose levels and/or GLP-1R agonist liraglutide.

Though poor glycemic control and insulin treatment are reported to be associated with sarcopenia in type 2 diabetes, 1 diabetes may a stronger risk for sarcopenia. We therefore studied the effect of control, therapy on prevalence characteristics sarcopenia.A total 812 Japanese patients (type 1: n = 57; 2: 755) were enrolled this study. Sarcopenia was defined as low handgrip strength or slow gait speed appendicular skeletal muscle mass.Among participants aged ≥65 years, rate higher among...

Abstract To localize the MHC-linked diabetogenic genes in nonobese diabetic (NOD) mouse, a recombinational hotspot from B10.A(R209) mouse was introduced to region between MHC class I K and II A of NOD with site centromeric Lmp2/Tap1 complex by breeding two strains. Replacement same R209 mice prevented development diabetes (from 71 3%) insulitis 61 15%) N7 intra-MHC recombinant mice. Similarly, replacement A, E D diseases (diabetes, 0%; insulitis, 3%). In addition genes, there are at least Lmp2.
