Cardiovascular risk and quality of life in supermarket cashiers: The role of physical activity.

Background: Occupations might influence the employees' psychophysical conditions and an important issue is the human activity mechanization, which favors a hypokinetic work status and leads to several chronic diseases. One of the most hypokinetic occupations is the supermarket cashier, in which the individual may spend many hours a day in the same body position.

Objective: The goal of this study was to evaluate the association between cardiovascular risk, quality of life and physical activity level in supermarket cashiers.

Ocimum basilicum but not Ocimum gratissimum present cytotoxic effects on human breast cancer cell line MCF-7, inducing apoptosis and triggering mTOR/Akt/p70S6K pathway.

Breast cancer is the major cause of death by cancer in women worldwide and in spite of the many drugs for its treatment, there is still the need for novel therapies for its control. Ocimum species have been used by traditional medicine to control several diseases, including cancer. We have previously characterized the antidiabetic properties of the unfractionated aqueous leaf extracts of Ocimum basilicum (OB) and Ocimum gratissimum (OG), modulating glucose metabolism in diabetic mice.

Effect of flaxseed on choroid-sclera complex thickness and on LDL oxidation in the sclera, choroid and retina of diet-induced hypercholesterolaemic rabbits.

The aim of the present study was to evaluate the effect of flaxseed on choroid-sclera complex thickness and on LDL oxidation in the sclera, choroid and retina of diet-induced hypercholesterolaemic rabbits. New Zealand male albino rabbits (n 21) were divided into two groups: group 1 (G1; n 11), fed a hypercholesterolaemic diet, and group 2 (G2; n 10), fed a hypercholesterolaemic diet enriched with flaxseed flour. The serum concentrations of total cholesterol (TC), LDL-cholesterol (LDL-C), HDL-cholesterol, TAG and fasting blood glucose were determined at the start of the experiment and on the day of killing (8th week).

Muscle-type 6-phosphofructo-1-kinase and aldolase associate conferring catalytic advantages for both enzymes.

6-Phosphofructo-1-kinase (PFK) and aldolase are two sequential glycolytic enzymes that associate forming heterotetramers containing a dimer of each enzyme. Although free PFK dimers present a negligible activity, once associated to aldolase these dimers are as active as the fully active tetrameric conformation of the enzyme. Here we show that aldolase-associated PFK dimers are not inhibited by clotrimazole, an antifungal azole derivative proposed as an antineoplastic drug due to its inhibitory effects on PFK.
