Association of the intestinal fatty acid binding protein Ala54Thr polymorphism and abdominal adipose tissue in African-American and Caucasian women

Genetic variants in the intestinal fatty acid-binding protein-2 (FABP2) gene have been associated with body composition phenotypes. We examined the association between the Ala(54)Thr variant in the FABP2 gene and levels of visceral (VAT) and sc (SAAT) abdominal fat in a group of 223 premenopausal African-American (n = 103) and Caucasian (n = 120) women.

Dairy intake, obesity, and metabolic health in children and adolescents: knowledge and gaps

There is an urgent need to identify nutrition-related risk factors for obesity and the metabolic syndrome, because the prevalence of these conditions continues to rise among children and adolescents. While some studies suggest that dairy and calcium intake may attenuate obesity and the metabolic syndrome, others do not support these findings. In addition, very little research has been done in children and adolescents, especially in minority youth, who are at the greatest risk for obesity and metabolic dysfunctions.

Dietary fiber and fat are associated with excess weight in young and middle-aged US adults



To examine relative associations of dietary composition variables with body mass index (BMI; calculated as kg/m2) among young and middle-aged US adults. We hypothesized that in subjects with physiologically plausible reported energy intakes, fiber intake would be inversely associated with BMI, independent of other dietary composition and sociodemographic variables.

Evidence for correlations between distant intentionality and brain function in recipients: a functional magnetic resonance imaging analysis

This study, using functional magnetic resonance imaging (fMRI) technology, demonstrated that distant intentionality (DI), defined as sending thoughts at a distance, is correlated with an activation of certain brain functions in the recipients. Eleven healers who espoused some form for connecting or healing at a distance were recruited from the island of Hawaii. Each healer selected a person with whom they felt a special connection as a recipient for DI. The recipient was placed in the MRI scanner and isolated from all forms of sensory contact from the healer.

Effects of consuming mycoprotein, tofu or chicken upon subsequent eating behaviour, hunger and satiety

This study tested if: (1) a preload of mycoprotein and tofu consumed before a lunch meal have a greater effect on satiety when compared to achicken preload, (2) the mycoprotein and tofu preloads, compared to chicken, are not associated with compensation or eating more food at asubsequent dinner meal. These hypotheses were tested in a controlled laboratory study using universal eating monitors to measure food intake and visual analogue scales to monitor hunger and satiety. Forty-two overweight adult females consumed three meals in the laboratory on 3 test days.

Echinacea alkylamides inhibit interleukin-2 production by Jurkat T cells

Alkylamides present in Echinacea species have reported immunomodulatory actions, yet their direct effects on T lymphocytes, key mediators of antiviral immunity, are poorly understood. We hypothesized that constituents present in ethanolic extracts of Echinacea species exert direct immunomodulatory effects on human Jurkat T cells. Modulation of IL-2 production by submaximally stimulated Jurkat cells was determined in response to treatment with extracts prepared from dried aerial parts of Echinacea purpurea.

Inhibition of PP2A, but not PP5, mediates p53 activation by low levels of okadaic acid in rat liver epithelial cells

The microbial toxin okadaic acid (OA) specifically inhibits PPP-type ser/thr protein phosphatases. OA is an established tumor promoter with numerous cellular effects that include p53-mediated cell cycle arrest. In T51B rat liver epithelial cells, a model useful for tumor promotion studies, p53 activation is induced by tumor-promoting (low nanomolar) concentrations of OA. Two phosphatases sensitive to these concentrations of OA, PP2A and protein phosphatase 5 (PP5), have been implicated as negative regulators of p53.
