Background. Naturally occurring substances from the flavanol and anthocyanin family of polyphenols have been proposed to exert beneficial effects in the course of obesity. We hypothesized that their effects on attenuating obesity-induced dyslipidemia as well as the associated inflammatory sequelae especially have health-promoting potential....

Excessive crying, often described as infantile colic, is the cause of 10% to 20% of all early pediatrician visits of infants aged 2 weeks to 3 months. Although usually benign and selflimiting, excessive crying is associated with parental exhaustion and stress. However, and underlying organic cause is found in less than 5% of these infants. In...

Hoodia gordonii extract was orally administered by gavage to groups of 22 female New Zealand white rabbits from day 3-28 after mating at doses of 0 (control), 3, 6 or 12. mg/kg bodyweight/day. These doses were reached by a dose escalation phase between days 3 and 7 after mating. As well as a vehicle control group, a control group pair-fed to the...

Hoodia gordonii extract (0, 5, 15 or 50. mg/kg body weight/day, n= 24 mice/group) was orally administered by gavage to female CD-1 mice from gestation days 5-17. On gestation day 18 the females were euthanized and examined. Treatment at 50. mg/kg/day caused a marked reduction in feed intake and body weight gain. Feed consumption was sporadically...

The effects of a basil extract on the sulfation and concomitant DNA adduct formation of the proximate carcinogen 1′-hydroxyestragole were studied using rat and human liver S9 homogenates and the human hepatoma cell line HepG2. Basil was chosen since it contains the procarcinogen estragole that can be metabolized to 1′-hydroxyestragole by...

Specific IgE sera screening studies are employed to investigate protein cross-reactivity. Such nonfunctional immunochemical methods cannot measure the biological activity of proteins. Therefore, an assay using RBL cells transfected with human FcεRI was developed. Our objective was to evaluate the degranulation of three cell-lines expressing...

Probiotics are claimed to beneficially affect the immune system and their involvement in allergy prevention is being investigated extensively. However, the efficacy of probiotics in allergy prevention remains controversial. We investigated whether the probiotic Lactobacillus casei Shirota (LcS) could modulate the food allergic response against...

Grain is an important source of phytochemicals, which have potent antioxidant capacity. They have been implicated in the beneficial health effect of whole grains in reducing cardiovascular disease and type 2 diabetes. The aim of the present study was to identify the most important antioxidant fractions of wheat grain. It was found that the...

An on-line HPLC screening method for detection of inhibitors of human cytochrome P450 1A2 in extracts was developed. HPLC separation of extracts is connected to a continuous methoxyresorufin-O-demethylation (MROD) assay in which recombinant human P450 1A2 converts methoxyresorufin to its fluorescent metabolite resorufin. The system was tested...

Background: Reports of lupine allergy are increasing as its use in food products increases. Lupine allergy might be the consequence of cross-reactivity after sensitization to peanut or other legumes or de novo sensitization. Lupine allergens have not been completely characterized. Objectives: We sought to identify allergens associated with...

Dendritic cells are believed to play an essential role in regulating the balance between immunogenic and tolerogenic responses to mucosal Ags by controlling T cell differentiation and activation via costimulatory and coinhibitory signals. The CD28/CTLA-4-CD80/CD86 signaling pathway appears to be one of the most important regulators of T cell...

Background: Naturally occurring CD4+CD25+ regulatory T cells (Tregs) play a critical role in the maintenance of self-tolerance and it has been suggested that these Tregs may also be involved in preventing allergic disease. Objective: The precise role of CD4+CD25+ T cells in the regulation of allergic responses to mucosal antigens remains to be...

A proof-of-concept study to assess the safety and efficacy of a traditional Chinese medicine formula as treatment for primary dysmenorrhea showed no statistically significant benefit over placebo. However, some efficacy parameters suggested possible superiority of the active treatment and so a larger study needs to be performed to determine...

There is a great interest in the pharmacological properties of cannabinoid like compounds that are not linked to the adverse effects of Δ9-tetrahydrocannabinol (THC), e.g. psychoactive properties. The present paper describes the potential immuno-modulating activity of unheated Cannabis sativa extracts and its main non-psychoactive constituent Δ9...

Background: Epidemiologic studies suggest that garlic may have beneficial effects on risk factors associated with cardiovascular disease (CVD). However, these findings are not unambiguously supported by randomized placebo-controlled clinical trials. Objective: We sought to investigate the effects of a chemically well-characterized garlic...

Background: The brain plays a crucial role in the decision to eat, integrating multiple hormonal and neural signals. A key factor controlling food intake is selective satiety, ie, the phenomenon that the motivation to eat more of a food decreases more than does the motivation to eat foods not eaten. Objective: We investigated the effect of...
