The role of defective glucose transport in the pathogenesis noninsulin-dependent diabetes (NIDDM) was examined Zucker diabetic fatty rats, a model NIDDM. As human NIDDM, insulin secretion unresponsive to 20 mM glucose. Uptake 3- O -methylglucose by islet cells less than 19% controls. β cell transporter (GLUT-2) immunoreactivity and amount GLUT-2 messenger RNA were profoundly reduced. Whenever fewer 60% GLUT-2-positive, response absent hyperglycemia exceeded 11 plasma We conclude that NIDDM...

GLUT2 underexpression has been reported in the +-cells of Zucker diabetic fatty rats and db/db mice, models spontaneously occurring NIDDM with antecedent obesity. To determine whether a nonobese rodent model exhibit same abnormalities GLUT2, we studied Goto-Kakizaki rats. In these mildly animals glucose-stimulated insulin secretion was reduced at all ages examined from 8 to 48 wk. normal control Wistar rats, immunostainable present on insulin-positive cells pancreatic islets. Only 85% were...

A cDNA termed reg was recently isolated by differential screening of a library prepared from regenerating islets pancreatic remnants rats subjected to 90% pancreatectomy and nicotinamide treatment. This led speculation that this gene may be involved in expansion β-cell mass. In the current study we have measured expression after implantation resection solid insulinoma tumor into rats, manuevers known, respectively, reduce reexpand volume β-cells islet. Animals with an implanted became...

Malnutrition is associated with adverse outcomes in patients diabetic kidney disease (DKD). However, it uncertain which nutritional assessment tools are most effective predicting the of DKD. This retrospective study was conducted at a single center and included 367 diagnosed DKD based on biopsy results between August 2009 December 2018. Four indices, namely Prognostic Nutritional Index (PNI), Geriatric Risk (GNRI), Triglycerides (TG) × Total Cholesterol (TC) Body Weight (BW) (TCBI),...

Background Diabetic bladder dysfunction (DBD) is a common urinary complication in diabetic patients, significantly affecting their overall well-being and quality of life, placing considerable burden on healthcare resources. Early prevention crucial; however, the absence simple effective tool to predict DBD onset remains significant challenge. This study aims identify risk factors for patients with type 2 diabetes mellitus (T2DM) develop predictive nomogram clinical application. Methods...

Arterial old-long-segment thrombus is a difficult-to-handle complication in brachio-cephalic fistula, leading to totally chronic occlusion, fistula dysfunction, and potential upper limb ischemia. This case study presented the successful clinical experience of using Fogarty adherent clot catheter remove an (15 cm) brachial artery, which was guided by ultrasound. The procedure resulted long-term patency arteriovenous with no early or delayed complications. highlighted effectiveness, safety,...

Abstract To identify the factors associated with serum total bilirubin (STB) and determine whether STB is independently diabetic retinopathy (DR) or kidney disease (DKD), 1,665 Chinese patients type 2 diabetes (T2DM) (248 outpatients newly diagnosed T2DM [NDM] 1,417 inpatients previously [PDM]) were studied. Clinical biochemical information was collected, a single nucleotide polymorphism (rs6704078) of UGT1A1 gene genotyped in 1,059 individuals. Multiple linear regression showed that...

BACKGROUND Endoscopic submucosal dissection (ESD) is a standardized therapeutic approach for early carcinoma of the digestive tracts. In this regard, process histopathological diagnosis requires standardization. However, uneven development healthcare in China, especially eastern and western creates challenges sharing diagnostic process. AIM To optimize ESD specimen sampling, embedding slide production, to provide complete accurate pathological reports. METHODS We established practical...
