Iron-Sensing Proteins that Regulate Hepcidin and Enteric Iron Absorption
The human body cannot actively excrete excess iron. As a consequence, iron absorption must be strictly regulated to ensure adequate iron uptake and prevent toxic iron accumulation. Iron absorption is controlled chiefly by hepcidin, the iron-regulatory hormone. Produced by the liver and secreted into...

Plasma zinc, copper, and erythrocyte superoxide dismutase in children with phenylketonuria.
We studied the effects of phenylalaline restricted diets in 42 children with PKU (P) and 31 normal (N) children, aged 1-12 y, divided into two groups (below and above 7 y). Plasma zinc and copper were analyzed by means of atomic spectrophotometry, and superoxide dismutase (CuZnSOD) activity was meas...
The optimal ratio of fat-to-carbohydrate in the diet.
A major issue in human nutrition is the optimal relation of carbohydrate-to-fat in the diet. According to some investigators, a high proportion of fat energy to total energy favors the development of several chronic diseases. Among these are obesity, coronary heart disease, diabetes, and cancer. The...
Re: Glutamine homologues and derivatives: a limiting factor in current artificial nutrition by F.H.R. Pesty, PharmD and F. Sultan, PhD.
Malnutrition and wasting, immunodepression, and chronic inflammation as independent predictors of survival in HIV-infected patients.
To analyze the long-term survival factors associated with HIV infection, a prospective follow-up study of 165 HIV-infected patients was performed after a clinical, nutritional, and biological evaluation. Survival rate could be determined in 129 patients after a follow-up of 42 mo before the use of p...
Health care advocacy in world health.
Tea and health.
The possible beneficial effects of tea consumption in the prevention of cancer and cardiovascular diseases have been demonstrated in animal models and suggested by studies in vitro. Similar beneficial effects, however, have not been convincingly demonstrated in humans: beneficial effects have been d...
