Efficacy of quercetin against chemically induced murine oral squamous cell carcinoma.

Oral squamous cell carcinoma (OSCC) is the most common form of head and neck cancer, and oxidative damage is associated with the development of OSCCs. Antioxidants have therefore been proposed for use as chemoprotective agents against different types of cancer. In the present study, the effect of the antioxidant quercetin, administered at doses of 10 and 100 mg/kg/day, was investigated in an experimental murine model of 4-nitroquinoline 1-oxide (4-NQO)-induced carcinogenesis.

Antibacterial Activity, Antioxidant Effect and Chemical Composition of Propolis from the Región del Maule, Central Chile.

Propolis is commercialized in Chile as an antimicrobial agent. It is obtained mainly from central and southern Chile, but is used for the same purposes regardless of its origin. To compare the antimicrobial effect, the total phenolic (TP), the total flavonoid (TF) content and the phenolic composition, 19 samples were collected in the main production centers in the Región del Maule, Chile.

High levels of iron status and oxidative stress in patients with metabolic syndrome.

Studies concerning oxidative stress (OxE) parameters have increased, mainly because of its important role in cardiovascular diseases and diabetes complications. The main objective of this study was to evaluate iron nutrition status and oxidative stress parameters in subjects that had developed metabolic syndrome (MetS). Subjects from the Research Program of Risk Factors for Cardiovascular Disease (n = 155) were studied (ages ranging from 45 to 65 years old) and classified according to the Adult Treatment Panel III criterion.

Inhibition of human topoisomerase I and activation of caspase-3 by aza-angucyclinones and arylaminopyrimido[4,5-c]isoquinoline-7,10-quinones.

Cancer is the second cause of death in the world after cardiovascular diseases. Cancer cells acquire capacities not present in normal cells, such as self-sufficiency, resistance to antiproliferative stimuli, evasion of apoptosis, unlimited replication, invasiveness and metastasis. Consequently, it is of major interest to explore and develop molecules with anticancer activity directed to specific targets.

High levels of hsCRP are associated with carbohydrate metabolism disorder.

Aim: To determine risk parameters associated with high values of high sensitive C-reactive protein (hsCRP) in subjects with different glucose fasting levels.

Methods: Anthropometric parameters, arterial pressure, glycemia, lipid profile, uric acid, and hsCRP were studied in a population of 513 individuals between 40 and 65 years.

Results: In total, 349 (68.

Elevated concentration of asymmetric dimethylarginine (ADMA) in individuals with metabolic syndrome.

The metabolic syndrome (MS) is a cluster of pathophysiological alterations that includes the presence of hypertension, insulin resistance, dyslipidemia, and abdominal obesity. MS is associated with increased risk of developing diabetes and cardiovascular diseases. Endothelial dysfunction with impaired nitric oxide (NO) bioavailability has been implicated in insulin resistance and hypertension.

Cross-talk between body iron stores and diabetes: iron stores are associated with activity and microsatellite polymorphism of the heme oxygenase and type 2 diabetes.

To assess the relationship between the length of (GT)n repeats in HO-1 gene promoter and heme oxygenase (HO) enzymatic activity in mononuclear cells with iron (Fe) stores in type 2 diabetic mellitus (DM2) patients and metabolic syndrome (MS) subjects, we studied 163 patients with DM2, 185 with MS, and 120 controls subjects. We evaluated iron status (hemoglobin and serum Fe, ferritin, and transferrin receptor), and we determined the length of (GT)n repeats in HO-1 gene promoter by capillary electrophoresis and HO enzymatic activity in mononuclear cells and assessed the relationship between these results and Fe stores. Only 1/163, 6/185, and 7/120 had iron deficiency anemia in DM2 patients, MS subjects, and controls, respectively.

Intervention with education and exercise reverses the metabolic syndrome in adults.

About 29% of the adult population of Talca, Chile, suffers from the metabolic syndrome (MS), a value higher than the national prevalence. Evidence indicates that exercise and nutritional changes reduce the predominance of this syndrome. The goal of this study was to evaluate the effects of a structured interventional program of physical activity and nutritional counseling in adults with MS.

Inhibitory effect of three C-glycosylflavonoids from Cymbopogon citratus (Lemongrass) on human low density lipoprotein oxidation.

Increased concentrations of soluble vascular cell adhesion molecule-1 and soluble CD40L in subjects with metabolic syndrome.

Metabolic syndrome (MS) is associated with a high incidence rate of cardiovascular disease. It is characterized by abdominal obesity, elevated blood pressure, atherogenic dyslipidemia [high LDL-c (low density lipoprotein cholesterol) and low HDL-c (high density lipoprotein cholesterol)] and insulin resistance or glucose intolerance. In the context of MS, alterations in the plasmatic levels of some soluble forms of cell adhesion molecules can appear, e.

Increased concentration of plasminogen activator inhibitor-1 and fibrinogen in individuals with metabolic syndrome.

Metabolic syndrome (MS) is closely linked to a generalized metabolic disorder referred to as insulin resistance. Disturbances in the hemostasis and fibrinolytic systems are a feature of MS. The aim of this study was to determine the concentration levels of fibrinogen and plasminogen activator inhibitor-1 (PAI-1) in a group of patients with MS with respect to a non-MS group, and to evaluate their possible relation with other risk factors in MS.
