OBJECTIVE To assess the reliability of bioelectric impedance analysis (BIA) for predicting total body water (TBW) and extracellular water (ECW) in children affected by juvenile rheumatoid arthritis (JRA). SUBJECTS Thirty-nine children affected by JRA and 23 healthy children of similar age (11.0 +/- 3.6, range 3.0-19.0 y) were recruited for the study. METHODS TBW and ECW were measured by deu...

Excised root tips from dark-grown mung bean seedlings (Phaseolus aureus) that adhere to a negatively charged glass surface when irradiated with red light and release when irradiated by far-red light develop a positive bioelectric potential (about 1.0 millivolt) at the tip in red light and a negative bioelectric potential in far-red light. The sign of the bioelectric potential was repeatedly pho...

The aim of this study was to investigate the body composition and dietary intake of competitive club-level rhythmic gymnasts, who represent the larger cohort of the sport's practitioners. Fifty-five rhythmic gymnasts and 55 nonathlete females (13-19 years of age) were seen individually to collect a dietary recall and to take anthropometric data and bioelectric-impedance analysis. Gymnasts had l...

BACKGROUND Obesity has become a major public health challenge in recent years. Recent studies suggest that alterations of the gut microbiota by antibiotics could play an important role in obesity. METHODS We investigated this topic using 60 Wistar rats, which were divided into 3 experimental groups: rats treated with amoxicillin, rats treated with amoxicillin plus Saccharomyces boulardii and ...

OBJECTIVE To demonstrate that a nutritional support intervention, via naso-enteral tube-feeding or gastrostomy, has a significant impact on the nutritional status and body composition in severely malnourished children with cerebral palsy spastic quadriplegia. METHODS Thirteen patients with moderate/severe malnutrition and cerebral palsy spastic quadriplegia who were fed via naso-enteral tube-...

Nutritional status should be assessed at regular intervals as part of management of human immunodeficiency virus (HIV) infection. The simplest approach to assessment is serial weight measurement. A comprehensive nutritional assessment includes (1) anthropometric measurements of body composition; (2) biochemical measurements of serum protein, micronutrients, and metabolic parameters; (3) clinica...

A bioelectric battery can be implanted into the human body and relies on oxygen in the internal body fluid to produce electrical energy. In this work, a battery that uses polypyrrole doped with a biological polyelectrolyte (dextran sulfate, an anti-coagulant) as the cathode and bioresorbable Mg alloy (AZ61) as the anode was developed. This battery exhibited a discharge capacity of 565 mA h g-1 ...
