Endothelium-derived hyperpolarization (EDH) is an important signaling mechanism of endothelium-dependent vasorelaxation, and little attention has been paid to the EDH-type responses in female metabolic syndrome such as that observed with type-2 diabetes. We previously reported that EDH-type relaxation was impaired in superior mesenteric arteries from male Otsuka Long-Evans Tokushima Fatty (OLETF) rat, a model of type-2 diabetes, however, the response was unclear in female OLETF rat. Thus, the aim of this study was to examine if EDH-type relaxation was altered in superior mesenteric arteries isolated from female OLETF rats compared to age-matched, control female Long-Evans Tokushima Otsuka (LETO) rats at age 50-59 weeks...

BACKGROUND AND OBJECTIVES: Recent observational studies have suggested a positive association of white rice and protective associations of green tea and coffee with the risk of diabetes. However, none have examined the interaction between these dietary factors on the risk of diabetes. We prospectively investigated the effect modification of green tea and coffee on the association between rice and incident diabetes in elderly Japanese men and women. METHODS AND STUDY DESIGN: Among subjects who participated in the baseline survey (2004-2007), 11717 (91 %) subjects responded to the follow-up survey (2010-2012)...

Impairment of the insulin-degrading enzyme (IDE) is associated with obesity and type 2 diabetes mellitus (T2DM). Here, we used 4-mo-old male C57BL/6 interleukin-6 (IL-6) knockout mice (KO) to investigate the role of this cytokine on IDE expression and activity. IL-6 KO mice displayed lower insulin clearance in the liver and skeletal muscle, compared with wild type (WT), due to reduced IDE expression and activity. We also observed that after 3-h incubation, IL-6, 50 and 100 ng ml(-1), increased the expression of IDE in HEPG2 and C2C12 cells, respectively...

The solute carrier family 2 facilitated glucose transporter member 4 (GLUT4) plays a key role in the insulin-induced glucose uptake by muscle and adipose tissues. In prediabetes and diabetes, GLUT4 expression/translocation has been detected as reduced, participating in mechanisms that impair glycemic control. Recently, a class of short endogenous noncoding RNAs named microRNAs (miRNAs) has been increasingly described as involved in the posttranscriptional epigenetic regulation of gene expression. The present review focuses on miRNAs potentially involved in the expression of GLUT4 expression, and proteins related to GLUT4 and translocation in skeletal muscle, seeking to correlate them with insulin resistance and diabetes...

Diet, dietary patterns, and other environmental factors such as exposure to toxins are playing an important role in the prevention/development of many diseases, like obesity, type 2 diabetes, and consequently on the health status of individuals. A major challenge nowadays is to identify novel biomarkers to detect as early as possible metabolic dysfunction and to predict evolution of health status in order to refine nutritional advices to specific population groups. Omics technologies such as genomics, transcriptomics, proteomics, and metabolomics coupled with statistical and bioinformatics tools have already shown great potential in this research field even if so far only few biomarkers have been validated...

For decades, macular laser photocoagulation has been the standard of care in the treatment of diabetic macular edema (DME). With the relatively recent advent of anti-vascular endothelial growth factor (VEGF) agents, DME treatment has entered a new era. VEGF is a well-known pro-angiogenic and pro-permeability factor involved in the pathogenesis of DME. VEGF blockade has proven remarkably effective at reducing DME and improving visual acuity (VA) in eyes with center involved DME causing VA loss in several randomized controlled trials (RCTs)...

Diabetic retinopathy (DR) is a frequent complication of diabetes mellitus (DM). Persistent hyperglycemia leads to the activation of multiple cellular pathways involved in the pathogenesis of DR, resulting in increased inflammation, oxidative stress, and vascular dysfunction. DR has been considered a "chronic, low-grade inflammatory disease of the retina". However, an increasing body of evidence suggests that inflammation and neurodegeneration both occur in human diabetes even before the development of clinical signs of DR...

BACKGROUND/AIM: Aortic valve sclerosis (AVS) is characterized by lipid deposition and calcific infiltration on the edge of aortic leaflets without significant restriction of motion. The SYNTAX Score (SS) is an important method for evaluating coronary artery disease (CAD). Many studies showed that there is an important relation between the SS and undesired cardiac outcomes. In our study, we investigated the correlation between the SS and AVS by including both ACS and stable CAD cases. MATERIALS AND METHODS: We enrolled 543 patients with CAD who underwent coronary angiography into this cross-sectional study between September 2013 and September 2014...

Bed rest has been an established treatment in the past prescribed for critically illness or convalescing patients, in order to preserve their body metabolic resource, to prevent serious complications and to support their rapid path to recovery. However, it has been reported that prolonged bed rest can have detrimental consequences that may delay or prevent the recovery from clinical illness. In order to study disuse-induced changes in muscle and bone, as observed during prolonged bed rest in humans, an innovative new model of muscle disuse for rodents is presented...

Diabetic nephropathy is one of the most frequent, devastating, and costly complications of diabetes. The available therapeutic approaches are limited. Dipeptidyl peptidase type 4 (DPP-4) inhibitors represent a new class of glucose-lowering drugs that might have in addition reno-protective properties. DPP-4 exists in two forms: a plasma membrane-bound form and a soluble form, and can exert many biological actions mainly through its peptidase activity and interaction with extracellular matrix components. The kidneys have the highest DPP-4 expression level in mammalians...

BACKGROUND: Team-based chronic care models have not been widely adopted in community settings, partly due to their varying effectiveness in randomized control trials, implementation challenges, and concerns about physician acceptance. The Palo Alto Medical Foundation designed and implemented "Champion," a novel team-based model that includes new standard work (e.g. proactive patient outreach, pre-visit schedule grooming, depression screening, care planning, health coaching) to support patients' self-management of hypertension and diabetes...

BACKGROUND AND AIMS: Meta-analyses of randomized control trials investigating the association between incident diabetes and statin use showed an increased risk of new-onset diabetes (NOD) from 9% to 13% associated with statins. However, short follow-up period, unpowered sample size, and lack of pre-specified diagnostic criteria for diabetes detection could be responsible of an underestimation of this risk. We conducted a meta-analysis of published observational studies to evaluate the association between statins use and risk of NOD...

Circular RNAs (circRNAs) are a novel type of endogenous noncoding RNA gaining research interest in recent years. Despite this increase in interest, the mechanism of circRNAs in the pathogenesis of multiple cardiovascular diseases, particularly myocardial fibrosis, is rarely reported. In the following study, the expression profiles and potential mechanisms of circRNAs in mice myocardial fibrosis models in vitro are investigated. Previous research examining circRNA expression profiles of diabetic db/db mice myocardium using circRNA microarray found 43 circRNAs were abnormally expressed, including 24 up-regulated circRNAs and 19 down-regulated circRNAs...

Over the last 50 years, newly described species of Emmonsia-like fungi have been implicated globally as sources of systemic human mycosis (emmonsiosis). Their ability to convert into yeast-like cells capable of replication and extra-pulmonary dissemination during the course of infection differentiates them from classical Emmonsia species. Immunocompromised patients are at highest risk of emmonsiosis and exhibit high mortality rates. In order to investigate the molecular basis for pathogenicity of the newly described Emmonsia species, genomic sequencing and comparative genomic analyses of Emmonsia sp...

Patients with diabetes are at great risk to suffer many musculoskeletal disorders, such as tendinopathy, tendon rupture and impaired tendon healing. However, the pathogenesis of these tendon disorders still remains unclear. In this study, we aimed to investigate the effects of high glucose on cell proliferation, cell apoptosis and tendon-related markers expression of tendon-derived stem cells (TDSCs) in vitro. These findings might provide new insights into the pathogenesis of diabetic tendon disorders. The cell proliferative ability and apoptosis rate of TDSCs in different groups were evaluated by MTT assay and Annexin V-FITC/PI staining assay...

As of 2016, there is no evidence-based pathway to stratify the risk of chronic liver disease in a general population setting. Non-invasive tests of liver fibrosis might provide a mechanism for earlier diagnosis. These tests have been extensively validated in the hospital setting but their performance in a general population setting is unclear. We did a systematic review of non-invasive tests used to stratify patients at risk of clinically significant liver disease in a general population setting and report the prevalence of chronic liver disease as defined by these tests...
