Chrysophanol Relieves Cognition Deficits and Neuronal Loss Through Inhibition of Inflammation in Diabetic Mice.

Chrysophanol Relieves Cognition Deficits and Neuronal Loss Through Inhibition of Inflammation in Diabetic Mice. Neurochem Res. 2018 Mar 01;: Authors: Chu X, Zhou S, Sun R, Wang L, Xing C, Liang R, Kong Q Abstract Patients with diabetes mellitus are easy to experience diabetic encephalopathy (DE) and other cognition dysfunction, whereas the neural alterations in developing this disease are unknown yet. Chrysophanol (CHR) is one of traditional Chinese medicine which was reported to show protective effects in cognition dysfunction and inflammatory in previously studies. In this current study, whether CHR protects learning and memory dysfunctions induced by diabetes disease or not and underlying mechanisms were studied. DE model was induced by streptozotocin (STZ, i.p.) in ICR mice. CHR was administrated 3 days after STZ treated mice which was confirmed with diabetes for consecutive 6 days. Learning and memory function was tested by Morris water maze after the CHR injection. The morphology of neuronal cells in hippocampus CA3 region was stained by HE-staining. ELISA and Western blot assay were used to determine the levels of pro-inflammation cytokines (IL-1β, IL-4, IL-6, TNF-α) in hippocampus. Here, we demonstrated that mice harboring diabetes mellitus induced by STZ exhibit high blood glucose, learning and memory deficits detected by Morris water maze behavior tests. Application with CHR right after developing diabetes disease rescues p...

An 85-year-old man presented with left hemiparesis, too late for any intervention. Brain computed tomography (CT) revealed a right hemispheric infarct. He had a history of diabetes mellitus (on metformin, statin), hypertension (on losartan/lercanidipine), past smoking, COPD (on inhalers) and peripheral artery disease (on aspirin).

The present study sought to examine the therapeutic effect of a novel antidiabetic monomer combination (AMC) in treating type 2 diabetes mellitus (T2DM); while also elucidating the potential functional mechanism. Male C57BL/6J mice were fed a high-fat diet (HFD) for 12 weeks to establish T2DM. The AMC group showed significant reduction in weight, fasting blood glucose (FBG), serum total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C), and experienced reduced insulin resistance based on oral glucose tolerance testing (OGTT) and hyperinsulinemic-euglycemic clamp testing (“gold standard” for deter...

ConclusionsOur data suggest that GLP-1RA do not affect tacrolimus levels or transplant outcomes in solid organ transplant (SOT) recipients in the short term. GLP-1RA also seem to be as effective in SOT recipients for glycemic control and weight loss as in the non-transplant population with diabetes.

Collado-Mateo Adsuar Gusi The aim of this study was to analyze the effects of an 8-week whole-body vibration (WBV) on the quality of life, physical fitness, body composition, glycosylate hemoglobin (HbA1c), lipid profile, and foot health status in people with type II diabetes mellitus (T2DM). It was performed as a double-blinded randomized controlled trial of 90 people with T2DM. Primary care facilities were used. The 8-week WBV training consisted of maintaining a knee flexion at 45° during five to nine series of 30–60 s in a vibration frequency that oscillated between 12.5–18.5 an...

ConclusionsPatients with CMS were more likely to present with increased comorbidities. Patients with CMS undergoing CABG were at risk for worse short ‐term secondary postoperative outcomes and reduced long‐term survival. The data supports the need for further investigation for risk reduction surrounding operative revascularization.
