Characterization of hypotensive and vasorelaxant effects of PHAR-DBH-Me a new cannabinoid receptor agonist.

The effect of PHAR-DBH-Me, a cannabinoid receptor agonist, on different cardiovascular responses in adult male rats was analyzed. The blood pressure was measured directly and indirectly. The coronary flow was measured by Langendorff preparation, and vasomotor responses induced by PHAR-DBH-Me in aortic rings precontracted with phenylephrine (PHEN) were analyzed.

Effects of Oleamide on the Vasomotor Responses in the Rat.

Cardiovascular effects of endocannabinoids (eCBs) have generated considerable interest since it has been suggested that the eCB system could become the new pharmacological target, either by blocking its activity or by promoting its effects on several cardiovascular diseases such as hypovolemic and septic shock or hypertension. The purpose of this study was to examine the effects of oleamide on several vasomotor responses in adult rats. Blood pressure (BP) was measured both directly and indirectly.

Atorvastatin and Fenofibrate Increase the Content of Unsaturated Acyl Chains in HDL and Modify In Vivo Kinetics of HDL-Cholesteryl Esters in New Zealand White Rabbits.

Previous studies demonstrated modifications of high-density lipoproteins (HDL) structure and apolipoprotein (apo) A-I catabolism induced by the atorvastatin and fenofibrate combination. However, it remains unknown whether such structural and metabolic changes of HDL were related to an improvement of the HDL-cholesteryl esters (HDL-CE) metabolism. Therefore, we determined the structure of HDL and performed kinetic studies of HDL-CE radiolabeled with tritium in rabbits treated with atorvastatin, fenofibrate, and a combination of both drugs.

The purpose of this study was to determine the independent/synergistic effects of supplementation (six weeks, 4.5 g·day) and a systematic physical exercise program (six weeks, twice weekly) on the body composition and cardiorespiratory fitness of overweight and obese subjects.

Extremely low frequency electromagnetic field exposure and restraint stress induce changes on the brain lipid profile of Wistar rats.

Background: Exposure to electromagnetic fields can affect human health, damaging tissues and cell homeostasis. Stress modulates neuronal responses and composition of brain lipids. The aim of this study was to evaluate the effects of chronic extremely low frequency electromagnetic field (ELF-EMF) exposure, restraint stress (RS) or both (RS + ELF-EMF) on lipid profile and lipid peroxidation in Wistar rat brain.

Double-blind randomised controlled trial of the independent and synergistic effect of with exercise (ISESE) on general fitness, lipid profile and redox status in overweight and obese subjects: study protocol.

Introduction: In order to reduce cardiovascular disease risk factors, a healthy diet must include dietary antioxidants from different sources (eg, ) and regular practice of exercise should be promoted. There is some evidence from animal studies that and exercise decrease cardiovascular disease risks factors. However, very few studies have proved the independent or synergistic effect of plus exercise in humans.

Lipid droplets accumulation and other biochemical changes induced in the fungal pathogen Ustilago maydis under nitrogen-starvation.

In many organisms, the growth under nitrogen-deprivation or a poor nitrogen source impacts on the carbon flow distribution and causes accumulation of neutral lipids, which are stored as lipid droplets (LDs). Efforts are in progress to find the mechanism of LDs synthesis and degradation, and new organisms capable of accumulating large amounts of lipids for biotechnological applications. In this context, when Ustilago maydis was cultured in the absence of a nitrogen source, there was a large accumulation of lipid bodies containing mainly triacylglycerols.

Small HDL subclasses become cholesterol-poor during postprandial period after a fat diet intake in subjects with high triglyceridemia increases.

Background: Postprandial triglyceridemia may transitory affect the structure of HDL subclasses and probably their antiatherogenic properties but little is known in this field. We analyzed the HDL subclasses lipid content along postprandial period.

Methods: Fifteen metabolic syndrome (MS) patients and 15 healthy controls were enrolled.

[SPIRULINA AND ITS HYPOLIPIDEMIC AND ANTIOXIDANT EFFECTS IN HUMANS: A SYSTEMATIC REVIEW].

Several chronic transmissible (e.g. AIDS) and non transmissible diseases like cadiovascular disease, are associated with oxidative stress (EOX) and dyslipidemia.

[Risk factors and evolution of enterocutaneous fistula after terminal ostomy takedown].

Background: End-ileostomy or colostomies are constructed for source control in patients with severe abdominal sepsis. After takedown, enterocutaneous fistula represents one of the most feared complications.

Effect of Spirulina maxima on postprandial lipemia in young runners: a preliminary report.

Trained people exhibit low plasma concentrations of triacylglcyerols in both fasting and postprandial states. Exercise practice is commonly believed to improve postprandial lipemia. In addition, elevated postprandial lipemia is an indicator of poor lipid clearance, and it has been associated with atherosclerosis, insulin resistance, and obesity.

Methods: Thirty two male Wistar rats were arranged in four groups: control, EMF exposed, movement restrained (MR), and EMF + MR for 2 h.

Factors predictive of recurrence and mortality after surgical repair of enterocutaneous fistula.

Many enterocutaneous fistulas (ECF) require operative treatment. Despite recent advances, rates of recurrence have not changed substantially. This study aims to determine factors associated with recurrence and mortality in patients submitted to surgical repair of ECF.

Hepatoprotective effects of Spirulina maxima in patients with non-alcoholic fatty liver disease: a case series.

Introduction: Non-alcoholic fatty liver diseases range from simple steatosis to non-alcoholic steatohepatitis. The "two hits" hypothesis is widely accepted for its pathogenesis: the first hit is an increased fat flux to the liver, which predisposes our patient to a second hit where increasing free fatty acid oxidation into the mitochondria leads to oxidative stress, lipoperoxidation and a chain reaction with increased ROS. Clinical indications include abdominal cramps, meteorism and fatigue.

Protective effects of Spirulina maxima on hyperlipidemia and oxidative-stress induced by lead acetate in the liver and kidney.

Background: Oxidative damage has been proposed as a possible mechanism involved in lead toxicity, specially affecting the liver and kidney. Previous studies have shown the antioxidant effect of Spirulina maxima in several experimental models of oxidative stress. The current study was carried out to evaluate the antioxidant activity of Spirulina maxima against lead acetate-induced hyperlipidemia and oxidative damage in the liver and kidney of male rats.

Cardiovascular and metabolic effects of intensive Hatha Yoga training in middle-aged and older women from northern Mexico.

Background: Hatha Yoga (HY) can be an alternative to improve physical activity in middle-aged and older women. However, conventional HY (CHY) exercising may not result in enough training stimulus to improve cardiovascular fitness. The purpose of this study was to evaluate the effect of an intensive HY intervention (IHY) on cardiovascular risk factors in middle-aged and older women from Northern Mexico.
