Proteins, saccharides, and low molecular organic compounds in the blood, urine, saliva could potentially serve as biomarkers for diseases related to diet, lifestyle, use of illegal drugs. Lifestyle-related (LSRDs) such diabetes mellitus (DM), non-alcoholic steatohepatitis, cardiovascular disease, hypertension, kidney osteoporosis develop into life-threatening conditions. Therefore, there is an urgent need their early diagnosis. Advanced glycation end-products (AGEs) are associated with LSRDs may induce/promote LSRDs. The presence AGEs body fluids represent a biomarker Urine samples be used detecting AGEs, urine collection convenient non-invasive. However, detection identification AGE-modified proteins challenging, concentrations might extremely low. To address this issue, we propose new analytical approach. This strategy employs method previously introduced by us, which combines slot blotting, our unique lysis buffer named Takata’s buffer, polyvinylidene difluoride membrane, conjunction electrospray ionization-mass spectrometry (ESI)/matrix-assisted laser desorption/ionization-mass (MALDI-MS). novel detect proteins, peptides, free-type samples.

Urinary stones (urolithiasis) have been categorized as kidney (renal calculus), ureteric (ureteral calculus and ureterolith), bladder (bladder urethral (urethral calculus); however, the mechanisms underlying their promotion related injuries in glomerular tubular cells remain unclear. Although lifestyle-related diseases (LSRDs) such hyperglycemia, type 2 diabetic mellitus, non-alcoholic fatty liver disease/non-alcoholic steatohepatitis, cardiovascular disease are risk factors for urolithiasis, Recently, heat shock protein 90 (HSP90) on membrane of HK-2 human proximal epithelium has associated with adhesion urinary cytotoxicity. Further, HSP90 pancreatic breast can be modified by various advanced glycation end-products (AGEs), thus affecting function. Hypothesis 1: We hypothesized that HSP90s on/in types AGEs, they may affect functions it a key to reveal LSRDs urolithiasis. 2: considered possibility Japanese traditional medicines urolithiasis inhibit AGE generation. Of Choreito Urocalun (the extract Quercus salicina Blume/Quercus stenophylla Makino) used clinic, is Kampo medicine, while characteristic medicine. As contains quercetin, hesperidin, p-hydroxy cinnamic acid, which generation, we generation AGE-modified cells.
