Background. VRE is an endemic hospital-acquired organism in the US. There are no proven methods or means of decreasing or eliminating carriage of VRE which is a risk factor for invasive disease. Two small clinical studies showed reduction or elimination of VRE colonization using the probiotic LGG but neither study cultured stool for the presence of LGG, raising questions about whether effects o...

Experimental evidence suggests that probiotics might have beneficial effect on the toxicity of anticancer therapy. In this study, the Double Blind Clinical trial was used to collect information and data. Participants were randomly divided into two experimental groups (probiotic) and a control group (placebo) after obtaining the consent of the company. At the start of the study, during a meeting...

The effect of creatine and caffeine supplementation on muscle torque generation and relaxation was investigated in healthy male volunteers. Maximal torque (T(max)), contraction time (CT) from 0.25 to 0.75 of T(max), and relaxation time (RT) from 0.75 to 0.25 of T(max) were measured during an exercise test consisting of 30 intermittent contractions of musculus quadriceps (2 s stimulation, 2 s re...

The authors examined the impact of caffeine on human memory and predictions of memory (i.e., metamemory). On Day 1, 83 college students drank a sweetened beverage containing either caffeine (4 mg/kg body weight) or a placebo before they studied 40 pairs of words. While the participants studied, they predicted their future memory performance for each word pair. On Day 2, the participants again r...

Objectives: Nigella sativa is a medicinal plant that has long been used in traditional medicine for treating various conditions. Numerous animal studies provided evidences that the seed may elicit a broad anti-inflammatory/anti-oxidant activity. The aim of the present clinical trial was to evaluate anti-inflammatory and antioxidant properties of Nigella sativa oil in patients with rheumatoid ar...

This study investigated effects of caffeine ingestion (8 mg/kg) on maximum voluntary torque (MVT) and voluntary activation of the quadriceps during isometric, concentric and eccentric contractions. Fourteen subjects ingested caffeine and placebo in a randomized, controlled, counterbalanced, double-blind crossover design. Neuromuscular tests were performed before and 1 h after oral caffeine and ...

objective: type 2 diabetes mellitus is a complex metabolic disorder with adverse cardiovascular risk. chromium (cr) is an essential nutrient and its role in carbohydrate and lipid metabolism has not been clarified especially in iran. the aim of this study was to evaluate the effect of chromium picolinate administration on blood glucose, hba1c, lipid profile and lipid peroxidation in type 2 diab...

There is limited safety information about ferric carboxymaltose (FCM), a new intravenous iron preparation. This randomized, crossover study compared the safety and tolerability of double-blinded intravenous doses of FCM or placebo in patients with iron deficiency anemia. Subjects (559) with iron deficiency anemia received a dose of either FCM (15 mg/kg, maximum 1000 mg) over 15 minutes or place...

This study investigated the effects of two different doses of caffeine on endurance cycle time trial performance in male athletes. Using a randomised, placebo-controlled, double-blind crossover study design, sixteen well-trained and familiarised male cyclists (Mean ± s: Age = 32.6 ± 8.3 years; Body mass = 78.5 ± 6.0 kg; Height = 180.9 ± 5.5 cm VO2(peak) = 60.4 ± 4.1 ml x kg(-1) x min(-1)) compl...

Objective: Type 2 diabetes mellitus is a complex metabolic disorder with adverse cardiovascular risk. Chromium (Cr) is an essential nutrient and its role in carbohydrate and lipid metabolism has not been clarified especially in Iran. The aim of this study was to evaluate the effect of chromium picolinate administration on blood glucose, HbA1c, lipid profile and lipid peroxidation in type 2 diab...
