Mercury exposure and risks from dental amalgam in the US population, post-2000.

Dental amalgam is 50% metallic mercury (Hg) by weight and Hg vapour continuously evolves from in-place dental amalgam, causing increased Hg content with increasing amalgam load in urine, faeces, exhaled breath, saliva, blood, and various organs and tissues including the kidney, pituitary gland, liver, and brain. The Hg content also increases with maternal amalgam load in amniotic fluid, placenta, cord blood, meconium, various foetal tissues including liver, kidney and brain, in colostrum and breast milk. Based on 2001 to 2004 population statistics, 181.1 million Americans carry a grand total o…

Flow cytometric profiling of water buffalo milk EVs: how lactation stage drives phenotypic evolution and macrophage modulation.

INTRODUCTION: Milk is more than a traditional nutrient source; it serves as a crucial carrier for milk-derived extracellular vesicles (mEVs), food-derived nanoparticles with diverse effects connecting animal health and human nutrition to ecological stability. The primary goal of this study was to characterize the phenotype and functional impact of mEVs from water buffalo (Bubalus bubalis) across the lactation curve. The researchers aimed to determine how the transition from colostrum (Colo EVs) to early milk (EM-EVs) and mature milk (MM-EVs) alters the vesicles' physical properties and their a…

Sociocultural context of exclusive breastfeeding in Africa: A narrative review.

BACKGROUND AND AIMS: Although exclusive breastfeeding (EBF) has many benefits, it is not commonly practiced in several countries as a result … EBF is strongly rooted in every culture and is a culturally determined behavior. Some believe that colostrum is dirty and harmful to newborns and, thus, needs to be purified. Despite the belief that human milk is the best food for babies, mothers often complement human milk with other foods right from birth because of perceived lactation inadequacy. Most A …

Genetic selection against intrauterine growth retardation in piglets: a problem at the piglet level with a solution at the sow level.

BACKGROUND: In polytocous livestock species, litter size and offspring weight act antagonistically; in modern pig breeds, selection for increased litter size has resulted in lower mean birth weights, an increased number of small piglets and an increased number of those affected by varying degrees of intrauterine growth retardation (IUGR). IUGR poses life-long challenges, both mental, with morphological brain changes and altered cognition, and physical, such as immaturity of organs, reduced colostrum intake and weight gain. In pigs, head morphology of newborn piglets is a good phenotypic marker…
