BACKGROUND Iron and zinc deficiency are prevalent during infancy in low-income countries. OBJECTIVES The objectives were to examine whether a weekly supplement of iron, zinc, iron+zinc, or a micronutrient mix (MM) of 16 vitamins and minerals would alter infant development and behavior. DESIGN The participants were 221 infants from rural Bangladesh at risk of micronutrient deficiencies. Deve...

Objective: The study aimed to evaluate the physicochemical properties and nutrition of Moringa leaf extract. In addition, preliminary for preparation extract-loaded phytosomes a supplement. Methods: Extraction made using microwave-assisted extraction, followed by evaluation proximate analysis (water, total ash, acid-insoluble ash contents, residual n-hexane), phytochemical screening, such as cr...

The performance of microbial electrochemical cells depends upon microbial community structure and metabolic activity of the electrode biofilms. Iron as a signal affects biofilm development and enrichment of exoelectrogenic bacteria. In this study, the effect of ferrous iron on microbial communities of the electrode biofilms in microbial fuel cells (MFCs) was investigated. Voltage production sho...

The effect of iron in different forms on the proliferative response to mitogen and ferritin content of human mononuclear leukocytes (MNL) was studied in vitro. Iron-loaded transferrin (FeTF) but not apotransferrin (apoTF) significantly enhanced the mitogenic response of MNL in serum-free culture. Removal of TF from serum markedly reduced its effectiveness as a serum supplement. This effect coul...

Iron oxide is an important biological agent that has a key role in medical processes; however, the mechanism whereby it provides iron for human and animal cells and its biological uses remains unclear. We aimed to evaluate the effects of oral iron oxide on serum iron status and compare the results with those of iron sulfate as a reference salt. Fifteen adult rabbits were divided into 3 groups o...

A small RNA, RyhB, was found as part of a genomewide search for novel small RNAs in Escherichia coli. The RyhB 90-nt RNA down-regulates a set of iron-storage and iron-using proteins when iron is limiting; it is itself negatively regulated by the ferric uptake repressor protein, Fur (Ferric uptake regulator). RyhB RNA levels are inversely correlated with mRNA levels for the sdhCDAB operon, encod...

In developing countries, anemia and iron deficiency in early childhood are two highly prevalent public health problems. Providing caregivers with a powder containing multiple vitamins and minerals (also known as micronutrient powder or MNP) as a food supplement is a widely used strategy to combat these problems. However, concerns exist around MNP programs with regards to effectiveness and poten...
