Nephrolithiasis is a common renal disease with no effective medication. Sodium-glucose cotransporter-2 (SGLT2) inhibitors, an anti-diabetic agent, have diuretic and anti-inflammatory properties could prevent nephrolithiasis. Here, we investigated the potential of SGLT2 inhibition against nephrolithiasis using large-scale epidemiological data, animal models, cell culture experiments. This study included data diabetic patients (n = 1,538,198) available in Japanese administrative database...

The aortic regurgitant fraction was estimated noninvasively in 20 patients with regurgitation from systolic and pulmonary volume flow determined by duplex Doppler echocardiography. By assuming that an excess of the (AF) compared (PF) is due to flow, (RF) calculated as follows: RF(%) = (AF - PF)/AF X 100. flows were products integrals ejection velocities cross-sectional areas left right ventricular outflow tracts, respectively. estimate semiquantitative grading (1+ 4+) cineaortography...

The aim of this study was to assess the utility neutrophil-to-lymphocyte ratio (NLR), plate-let-to-lymphocyte (PLR), and systemic immune inflammation index (SII) as predictive biomarkers with oncological outcomes for metastatic renal cell carcinoma (mRCC) patients treated nivolumab ipilimumab (NIVO + IPI). We conducted a retrospective multicenter cohort assessing mRCC NIVO IPI at eight institutions in Japan. In study, follow-up period median 14 months. 1-year overall- progression-free...

Temozolomide (TMZ, 3,4-dihydro-3-methyl-4-oxoimidazo [5,1-d]-as-tetrazine-8-carboxamide) is a new alkylating agent with promising antitumour efficacy for malignant gliomas. The resistance of tumour cells to TMZ primarily associated levels the alkylguanine alkyltransferase (AGT). O6-benzylguanine (O6-BG), an inhibitor AGT, reduced TMZ. Recently, it has been demonstrated that chemosensitivity related decline in telomerase activity. However, unknown if sensitivity glioma correlates telomerase....

Abstract Renal congestion is an issue of cardiorenal syndrome in patients with heart failure. Recent clinical and basic studies suggest a renoprotective potential sodium–glucose cotransporter (SGLT) 2 inhibitors. However, the effect on renal its mechanism not fully understood. Thus, we aimed to clarify SGLT inhibition model. was induced left kidney male Sprague-Dawley rats by ligation inferior vena cava between veins. The SGLT2 inhibitor tofogliflozin or vehicle orally administered daily...
