BACKGROUND/AIMS: Oxidative stress plays an important role in the pathogenesis and progression of diabetic complications and antagonists of renin-angiotensin system and amlodipine have been reported previously to reduce oxidative stress. In this study, we compared the changes in oxidative stress markers after valsartan and amlodipine treatment in type 2 diabetic patients with hypertension and compared the changes in metabolic parameters. METHODS: Type 2 diabetic subjects with hypertension 30 to 80 years of age who were not taking antihypertensive drugs were randomized into either valsartan (n = 33) or amlodipine (n = 35) groups and treated for 24 weeks...

BACKGROUND AND OBJECTIVES: Insulin resistance (IR) is frequent in human immunodeficiency virus (HIV) infection and may be related to antiretroviral therapy (ART). Increased oxidative stress parameters and carbonyl protein are linked to insulin sensitivity. The present study is aimed to determine IR, its association with oxidative deoxy nucleic acid (DNA) damage in HIV-1-infected patients with different ART status. MATERIALS AND METHODS: In this case-control study, a total 600 subjects were included...

We attempted to investigate the therapeutic effects of deferiprone on DC rats and explore the underlying mechanism. Total 24 6-week-old male Wistar rats (weighing from 180 g to 220 g) were subjected to DC model construction and then randomly divided to three groups (8 rats per group): DC group, DC + 50 mg, and DC + 100 mg deferiprone treatment group. The 8 normal rats were considered as controls. After deferiprone treatment for 20 weeks, the blood samples were collected for the biochemical parameters test, including fasting glucose, HOMA-IR (homeostasis model assessment of the insulin resistance), serum iron, ferritin and transferrin saturation (TS)...

There was inconsistent evidence showing that vitamin D intake may be associated with reduced cancer risk due to optimized metabolic profile and reduced oxidative stress. However, we are not aware of any study evaluating the effects of vitamin D supplementation on clinical response and metabolic status of patients with endometrial hyperplasia (EH). This research was done to evaluate the effects of vitamin D supplementation on clinical response and metabolic status of patients with EH. This randomized, double-blind, placebo-controlled trial was conducted among 60 women diagnosed with EH...

Overconsumption of energy dense foods and sedentary lifestyle are considered as major causes of obesity-associated insulin resistance and abnormal glucose metabolism. Results from both cohort studies and randomized trials suggested that anthocyanins from berries may lower metabolic risks, however these reports are equivocal. The present study was designed to examine effects of six berries with structurally diverse anthocyanin profiles (normalized to 400 µg/g total anthocyanin content) on development of metabolic risk factors in the C57BL/6 mouse model of polygenic obesity...

BACKGROUND: Late gestational sleep fragmentation (SF) is highly prevalent particularly in obese women, and induces metabolic dysfunction in adult offspring mice. SF induces activation of the integrated stress response (ISR), which might be involved in metabolic disorders. We hypothesized that adult offspring of double mutant mice (DM) involving the critical ISR genes CHOP and GADD34 would be protected from developing obesity and insulin resistance following SF. METHODS: Time-pregnant CHOP/GADD34 DM and wild type (WT) mice were randomly assigned to sleep control (SC) or SF conditions during the last 5days of gestation...

Humans in modern societies typically consume food at least three times daily, while laboratory animals are fed ad libitum. Overconsumption of food with such eating patterns often leads to metabolic morbidities (insulin resistance, excessive accumulation of visceral fat, etc.), particularly when associated with a sedentary lifestyle. Because animals, including humans, evolved in environments where food was relatively scarce, they developed numerous adaptations that enabled them to function at a high level, both physically and cognitively, when in a food-deprived/fasted state...

Several lines of evidence point to the association of vitamin D deficiency with the different components of metabolic syndrome. Yet, the effect of vitamin D supplementation on metabolic syndrome is not clearly elucidated. Herein, we tested the hypothesis that administration of vitamin D, either alone or in combination of metformin can improve metabolic and structural derangements associated with metabolic syndrome. Fifty wistar rats were randomly assigned to serve either as normal control (10 rats) or metabolic syndrome rats, by feeding them with a standard or a high fat diet (HFD), respectively...

High fat diet-induced obesity is associated with insulin resistance (IR) and other chronic, diet related illnesses, including dementia. Alzheimer disease is the most common form of dementia, and is characterized by the presence of amyloid plaques and neurofibrillary tangles in brain. This study was designed to determine whether diet-induced changes in peripheral insulin sensitivity could contribute to alterations in brain insulin signaling and cognitive functions. Six week old, male C57BL/6NHsd mice were randomly assigned a high fat diet (40% energy from fat) with 42g/L liquid sugar (HFS) added to the drinking water or a normal chow diet (12% energy from fat) for 14weeks...

There is accumulating evidence that RAS inhibitors not only reduce blood pressure, but also exert pleiotropic effects, including a renoprotective effect, amelioration of insulin resistance, reduction in onset of diabetes, and suppression of cardiovascular remodelling,. However, the definite benefit of RAS inhibition in treatment of hypertension with CKD or DM is not conclusive. We previously performed the OlmeSartan and Calcium Antagonists Randomized (OSCAR) study comparing the preventive effect of high-dose ARB therapy versus ARB plus CCB combination therapy on cardiovascular morbidity and mortality in 1164 Japanese elderly hypertensive patients with baseline type 2 diabetes and/or CVD (Am J Med (2012))...
