Health effect of the New Nordic Diet in adults with increased waist circumference: a 6-mo randomized controlled trial.

submitted by: skp
BACKGROUND: The regional Mediterranean Diet has been associated with lower risk of disease. OBJECTIVE: We tested the health effects of the New Nordic Diet (NND), which is a gastronomically driven regional, organic, and environmentally friendly diet, in a carefully controlled but free-living setting. DESIGN: A total of 181 centrally obese men and women, with a mean (range) age of 42 y (20-66 y), body mass index (in kg/m(2)) of 30.2 (22.6-47.3), and waist circumference of 100 cm (80-138...

Zinc supplementation improves bone density in patients with thalassemia: a double-blind, randomized, placebo-controlled trial

submitted by: efung
BACKGROUND: Patients with thalassemia major (Thal) frequently have low plasma zinc, which has been associated with low bone mass. OBJECTIVE: The objective was to determine the effect of zinc supplementation on bone mass in patients with Thal. DESIGN: Forty-two subjects (21 females aged 10-30 y) with Thal and low bone mass were randomly assigned to receive 25 mg Zn/d or placebo. Bone mineral content (BMC) and areal bone mineral density (aBMD) were assessed by using dual-energy X-ray...

Generating Electricity More Efficiently with Multiphase Thermoelectric Converter

submitted by: MFerreiraJr
The Multiphase Thermoelectric Converter is a direct thermal-to-electrical energy conversion system designed in order to harvest most of the waste heat energy efficiently into electricity. Conceptually, it works by ionizing hot coolant in order to force it F=q(v × B) to push its ions against moving magnetic fields doing useful work converting thermal energy directly into electric power at high efficiency with almost no moving parts. Essentially, it can be comprised of two sets of concentric...

Cobalamin supplementation improves motor development and regurgitations in infants: results from a randomized intervention study

Background: During infancy, minor developmental delays and gas- trointestinal complaints are common, as is a biochemical profile in- dicative of impaired cobalamin status. Objective: We investigated whether cobalamin supplementation can improve development or symptoms in infants with biochemical signs of impaired cobalamin function and developmental delay or feeding difficulties. Design: Infants ,8 mo of age (n = 105) who were referred for feeding difficulties, subtle neurologic...

Belief beyond the evidence: using the presumed effect of breakfast on obesity

submitted by: awbrown
Background: Various intentional and unintentional factors in?uence beliefs beyond what scienti?c evidence justi?es. Two such factors are research lacking probative value (RLPV) and biased research reporting (BRR). Objective: We investigated the prevalence of RLPV and BRR in research about the proposition that skipping breakfast causes weight gain, which is called the proposed effect of breakfast on obesity (PEBO) in this article. Design: Studies related to the PEBO were synthesized...
