Olive Leaf Powder Modulate Insulin Production and Circulating Adipokines in Streptozotocin Induced Diabetic Rats.

Olives () have natural phytochemical compounds that are of great importance for their potential beneficially health effects. This study aimed to evaluate the effects of olive leaf powder (OLP) on insulin production and circulating adipokines in streptozotocin-induced diabetic rats. Forty Wistar-albino male rats, weighing 200-225 g were divided into four groups ( = 10); group I: Normal healthy rats received balanced diet; group II: Diabetic control rats receiving balanced diet; group III: Diabetic rats receiving balanced diet + standard antidiabetic drugs (metformin, 600 mg/bw) and group four: Diabetic rats received diet supplemented with 2.

Potential Role of L-Arginine and Vitamin E Against Bone Loss Induced by Nano-Zinc Oxide in Rats.

The purpose of this study was to illustrate the effects of zinc oxide nanoparticles (ZnO-NPs) administration on bone turnover and bone resorbing agents in rats and how L-arginine (L-arg) or vitamin E (vit E) co-administrations might affect them. Fasting rats were randomly divided into four groups (n = 10): G1-normal healthy animals; G2-ZnO-NPs-exposed rats (600 mg/kg1/day); G3-ZnO-NPs-exposed rats co-administrated L-arg (200 mg/kg1/day); G4-ZnO-NPs-exposed rats co-administrated vit E (200 mg/kg1/day). The ingredients were orally administered daily.

Alleviation of bone markers in rats induced nano-zinc oxide by qurecetin and α-lipolic acid.

The purpose of this study was to evaluate the potential protective effect of qurecetin (Qur) and α-lipolic acid (ALA) to modulate the perturbation of bone turnover which is induced by nano-zinc oxide (n-ZnO). Rats were fasted overnight and randomly divided into two groups: G1, normal healthy animals and the other rats were administered zinc oxide nanoparticles orally by guava in a dose of 600 mg/kg body weight/d for 5 sequential days in Wistar albino male rats. N-ZnO-exposed animals were randomly sub-divided into three groups: G2, n-ZnO-exposed animals; G3, n-ZnO-exposed animals co-treated with Qur (200 mg/kg daily); and G4, n-ZnO-exposed animals co-treated with ALA (200 mg/kg).

Potential Intervention of α- Lipoic Acid and Carnitine on Insulin Sensitivity and Anti-Inflammatory Cytokines Levels in Fructose-Fed Rats, a Model of Metabolic Syndrome.

The objective of this work was to evaluate the beneficial effect of α-lipoic acid (ALA) and L-carnitine (CAR) on insulin sensitivity and anti-inflammatory markers in animal model of metabolic syndrome (MS), high fructose (HF)-fed rats. Forty male rats were randomly divided into four groups (n = 10). Group 1(control rats, G1), animals were allowed to drink 0.

Vitamin D status and insulin resistance among young obese Saudi females.

Objectives: To evaluate the association of vitamin D level with insulin resistance, among healthy student's obese women, and to identify factors that may elucidate this association.

Methods: One hundred and forty-seven female students between the age group of 18 and 25 years were included in this cross-sectional study, and the related socio-demographic and anthropometric data were obtained. They were selected randomly from Aljouf University, Sakaka, Saudi Arabia between November 2013 and June 2014.

Unhealthy nutritional habits in university students are a risk factor for cardiovascular diseases.

Objective: To evaluate the relationship between the nutritional habits of university students with health parameters related to cardiovascular risk.

Methods: Three hundred and twelve students (180 females and 132 males; mean age 21.1 +/- 2.

Manipulation of flaxseed inhibits tumor necrosis factor-alpha and interleukin-6 production in ovarian-induced osteoporosis.

Objective: To evaluate the potential effects of whole flaxseed (FS), and/or flax oil (FO) incorporation into the diet on the level of pro-inflammatory cytokines in ovariectomized (OVX) rats model of osteoporosis.

Methods: This study was performed in the Food Science & Agriculture Collage, King Saud University, Kingdom of Saudi Arabia from October to December 2009. Forty-eight, 3-month-old female Sprague-Dawley rats were randomly divided into 6 groups: Group 1 - sham + control diet; Group 2 - OVX rats + basal diet; Group 3 - OVX + 20% whole FS; Group 4 - OVX rats + 40% FS; Group 5 - OVX rats + 5% FO; Group 6 - OVX rats + 10% FO.
