Fat type in diet is responsible for specific changes in gut microbiota (GM). Extra virgin olive oil (EVOO) has been shown to be beneficial for blood pressure and to produce effects on GM. To analyze the cause-effect relationship between intestinal microbial changes and blood pressure, we studied the effect of EVOO on fecal microbiota and systolic blood pressure (SBP) levels in spontaneously hypertensive rats (SHR). SHR were fed either an enriched EVOO diet or a standard diet for a period of 12 weeks. At the end of the experimental period, the microbial profiles in the feces were studied in both groups by using PCR-denaturing gradient gel electrophoresis...

Insulin resistance (IR) plays a major role in the pathogenesis of abdominal obesity, hypertension, coronary heart disease, atherosclerosis and diabetes. miR-21 and TGF-β/smads is closely related to IR. However, it remained elusive whether metformin improved skeletal muscle insulin resistance (IRSM) by regulating miR-21 and its target signal TGF-β1/smads expression. In this study, high-fat diet rats with IR model and IR-skeletal muscle L6 cells (L6-SMCs) model were established, insulin sensitive index (ISI) and Homeostasis model assessment of IR (HOMA-IR) were applied, miR-21 and TGF-β1/smads mRNA expression were examined by RT-PCR, smad3 and smad7 protein were detected by western-blotting and laser scanning confocal microscopy (LSCM), the valid target of miR-21 was detected by luciferase reporter gene assay...

OBJECTIVES: The authors sought to evaluate clinical outcomes of patients after an episode of acute heart failure (AHF) according to their adherence to the Mediterranean diet (MedDiet). BACKGROUND: It has been proved that MedDiet is a useful tool in primary prevention of cardiovascular diseases. However, it is unknown whether adherence to MedDiet is associated with better outcomes in patients who have already experienced an episode of AHF. METHODS: We designed a prospective study that included consecutive patients diagnosed with AHF in 7 Spanish emergency departments (EDs)...

Studies have suggested that the consumption of green tea reduces the risk of cardiovascular diseases. Although epigallocatechin gallate (EGCG) is the best studied active substance characteristic of green tea, previous results on EGCG do not appear sufficient to explain completely the mechanism of cardiovascular protection by green tea. Therefore, we investigated the effect of three different tea cultivars, "Yabukita," "Sofu," and "Sunrouge," which have characteristic flavonoid compositions, on the nitric oxide (NO) production and the related protein expression in the aorta of spontaneously hypertensive rats (SHRs) fed a high-salt diet...

Although increasing evidences suggest a relationship between hypertension and brain function for years, it is still unclear whether hypertension constitutes a risk factor for cognitive decline and its underlying mechanism. In the present study, an experimental animal model of hypertension simply by feeding rats with high salt diet was employed. We found that long-term high salt intake caused a marked increase of systolic blood pressure linked to a declined regional cerebral blood flow. Fear conditioning and morris water maze behavioral test revealed that high salt diet induced hippocampal dependent spatial reference memory deficits, while a decreased synaptogenesis without neuronal loss in hippocampus was observed in high salt treated rats...

OBJECTIVE: A high salt intake causes hypertension and leads to cardiovascular disease. Therefore, a low salt diet is now recommended to prevent hypertension and cardiovascular disease. However, it is still unknown whether an excessively low salt diet is beneficial or harmful for the heart. METHODS: Wistar Kyoto rats (WKYs) and spontaneously hypertensive rats (SHRs) received normal salt chow (0.9% salt diet) and excessively low salt chow (0.01% salt diet referred to as saltless diet) for 8 weeks from 8 to 16 weeks of age...

BACKGROUND: Arterial stiffness is known to be associated with a number of clinical conditions including hypertension, diabetes and dyslipidemia, and may predict cardiovascular events and mortality. However, causal links are hard to establish. Results from genome-wide association studies have identified only a few single nucleotide polymorphisms associated with arterial stiffness, the results have been inconsistent between studies and overlap with other clinical conditions is lacking. Our aim was to investigate a potential shared set of risk single nucleotide polymorphisms between relevant cardiometabolic traits and arterial stiffness...

High-fat sucrose (HFS) diet in aged individuals causes severe weight gain (obesity) with much higher risk of cardiovascular diseases such as hypertension or atherosclerosis. Endothelial dysfunction is a major contributor for these vascular disorders. We hypothesize that prolonged ingestion of HFS diet by aged mice would accentuate endothelial dysfunction in the small resistance arteries. Male C57BL/6J mice at 12 weeks of age were divided into four groups and fed either normal chow (NC) or high-fat sucrose diet (HFS)...

Context: Impaired insulin-mediated muscle microvascular recruitment (IMMR) in obese individuals may add to the development of metabolic insulin resistance and hypertension. Increased aldosterone levels have been linked to these obesity-related complications in severely to morbidly obese individuals, and have been found to interfere with microvascular function in experimental studies. Objectives: To investigate whether aldosterone levels are related to IMMR, insulin sensitivity and blood pressure in lean and moderately abdominally obese men, and to study the effect of weight loss on these variables...

Diabetic retinopathy is a microvascular complication of diabetes that threatens all individuals with diabetes, leading to vision loss or blindness if left untreated. It is frequently associated with diabetic macular edema, which can occur at any point during the development of diabetic retinopathy. The key factors known to lead to its development include hyperglycemia, hypertension, and the duration of diabetes. Though the diet is important in the development of diabetes, its role in diabetic retinopathy has not been clearly identified...

Largely due to the childhood obesity epidemic, there has been an increase in the prevalence of hypertension in children and adolescents. Obesity associated hypertension is the most common hypertension phenotype among adolescents. Approximately 30% of obese adolescents have elevated blood pressure (BP) or hypertension. Updated definitions of elevated BP and hypertension in adolescents are now similar to definitions of BP status in adults. For adolescents ≥13 years of age, elevated BP is 120 to 129/<80 mm Hg...

BACKGROUND: Systemic inflammation is a key process underlying cardiovascular disease (CVD) development, and CVD risk is significantly elevated in persons with type 1 diabetes (T1D). Youth with T1D exhibit increased levels of inflammation. Studies in persons without diabetes suggest that dietary quality influences inflammation, yet little is known about dietary influences on inflammation in youth with T1D. METHODS: This study evaluated the association of four distinct dietary quality indices (Dietary Approaches to Stop Hypertension (DASH), Healthy Eating Index 2010 (HEI2010), modified KIDMED and Total Antioxidant Capacity (TAC)) with biomarkers of inflammation (C-reactive protein (CRP), fibrinogen and interleukin-6 (IL-6)) in a sample of 2520 youth with T1D participating in the SEARCH for Diabetes in Youth Study...

Hyperlipidemia is a chronic disorder which plays an important role in the development of cardiovascular diseases, type 2 diabetes, atherosclerosis, hypertension and nonalcoholic fatty liver disease. Genipin is a metabolite from genipioside, which is an active component of the traditional Chinese medicine Gardenia jasminoides Ellis, and has been recognized as a beneficial compound against metabolic disorders. However, whether it can correct over-nutrition-induced dyslipidemia is still unknown. In this study, the effects of genipin on attenuating hyperlipidemia and hepatic lipid accumulation were investigated using normal and obese mice induced by a high-fat diet and primary hepatocytes treated by free fatty acids...

INTRODUCTION: The metabolic syndrome (MetS) leads to cardiac vascular injury, which may reflect in increased retention of endothelial progenitor cells (EPC). Coronary endothelial cell (EC) mitochondria partly regulate vascular function and structure. We hypothesized that chronic mitoprotection would preserve EC mitochondria and attenuate coronary vascular injury and dysfunction in swine MetS. METHODS: Pigs were studied after 16 weeks of diet-induced MetS, MetS treated for the last 4 weeks with the mitochondria-targeted peptide elamipretide (ELAM, 0...

Mouse maternal low protein diet exclusively during preimplantation development (Emb-LPD) is sufficient to programme altered growth and cardiovascular dysfunction in offspring. Here, we use an in vitro model comprising preimplantation culture in medium depleted in insulin and branched-chain amino acids (BCAA), two proposed embryo programming inductive factors from Emb-LPD studies, to examine the consequences for blastocyst organisation and, after embryo transfer (ET), postnatal disease origin. Two-cell embryos were cultured to blastocyst stage in defined KSOM medium supplemented with four combinations of insulin and BCAA concentrations...
