TLDR
This reviews pays special attention to microRNAs and their modulatory role in diabetes‐induced vascular dysfunction and some therapeutic strategies for preventing and restoring diabetic endothelial dysfunction are highlighted.Abstract:
Endothelial cells, as well as their major products nitric oxide (NO) and prostacyclin, play a key role in the regulation of vascular homeostasis. Diabetes mellitus is an important risk factor for cardiovascular disease. Diabetes-induced endothelial dysfunction is a critical and initiating factor in the genesis of diabetic vascular complications. The present review focuses on both large blood vessels and the microvasculature. The endothelial dysfunction in diabetic macrovascular complications is characterized by reduced NO bioavailability, poorly compensated for by increased production of prostacyclin and/or endothelium-dependent hyperpolarizations, and increased production or action of endothelium-derived vasoconstrictors. The endothelial dysfunction of microvascular complications is primarily characterized by decreased release of NO, enhanced oxidative stress, increased production of inflammatory factors, abnormal angiogenesis, and impaired endothelial repair. In addition, non-coding RNAs (microRNAs) have emerged as participating in numerous cellular processes. Thus, this reviews pays special attention to microRNAs and their modulatory role in diabetes-induced vascular dysfunction. Some therapeutic strategies for preventing and restoring diabetic endothelial dysfunction are also highlighted.read more

Beneficial Effects of Adiponectin on Glucose and Lipid Metabolism and Atherosclerotic Progression: Mechanisms and Perspectives
Hidekatsu Yanai,Hiroshi Yoshida +1 more
TL;DR: The findings suggest that high levels of circulating adiponectin can protect against atherosclerosis, and weight loss, exercise, nutritional factors, anti-diabetic drugs, lipid-lowering drugs, and anti-hypertensive drugs have been associated with an increase of serum adiponECTin level.

Heart in space: effect of the extraterrestrial environment on the cardiovascular system.
TL;DR: Empirical findings suggest an increased risk of late cardiovascular disease even with low doses of radiation, and the peculiar biological effectiveness of heavy ions in cosmic rays might increase this risk substantially.

TL;DR: It is proposed that a consensus methodology for FMD is universally adopted to minimize technical variation between studies, and that reference FMD values are established for different populations of healthy individuals and patient groups.

Mitochondrial dysfunction in diabetic kidney disease.
TL;DR: Understanding the pathobiology of mitochondrial dysfunction in DKD would facilitate the development of novel therapeutic strategies, and may serve as a marker of mitochondrial damage inDKD.

Exercise training and endothelial function in patients with type 2 diabetes: a meta-analysis
TL;DR: Exercise training, in particular aerobic and combined exercise, improves endothelial function in type 2 diabetes patients, but such an improvement appears to be weakened compared with non-diabetics.

Global Prevalence of Diabetes: Estimates for the year 2000 and projections for 2030
TL;DR: Findings indicate that the "diabetes epidemic" will continue even if levels of obesity remain constant, and given the increasing prevalence of obesity, it is likely that these figures provide an underestimate of future diabetes prevalence.

The obligatory role of endothelial cells in the relaxation of arterial smooth muscle by acetylcholine
TL;DR: It is demonstrated that relaxation of isolated preparations of rabbit thoracic aorta and other blood vessels by ACh requires the presence of endothelial cells, and that ACh, acting on muscarinic receptors of these cells, stimulates release of a substance(s) that causes relaxation of the vascular smooth muscle.

Identification of novel genes coding for small expressed RNAs.
TL;DR: It is shown that many 21- and 22-nt expressed RNAs, termed microRNAs, exist in invertebrates and vertebrates and that some of these novel RNAs are highly conserved, which suggests that sequence-specific, posttranscriptional regulatory mechanisms mediated by smallRNAs are more general than previously appreciated.

The incretin system: glucagon-like peptide-1 receptor agonists and dipeptidyl peptidase-4 inhibitors in type 2 diabetes
TL;DR: Clinical trials with the incretin mimetic exenatide and liraglutide show reductions in fasting and postprandial glucose concentrations, and haemoglobin A1c (HbA1c) associated with weight loss, but long-term clinical studies are needed to determine the benefits of targeting the inc retin axis for the treatment of type 2 diabetes.

Nutrient control of glucose homeostasis through a complex of PGC-1alpha and SIRT1.

TL;DR: It is shown that the Sir2 homologue, SIRT1 controls the gluconeogenic/glycolytic pathways in liver in response to fasting signals through the transcriptional coactivator PGC-1α, and this findings have strong implications for the basic pathways of energy homeostasis, diabetes and lifespan.
