The U.S. Federal Food, Drug, and Cosmetic Act (Ffdca) defines infant formula as "a food which purports to be or is represented for special dietary use solely as a food for infants because it simulates human milk or its suitability as a…
Television viewing is a highly prevalent sedentary behavior among older adults, yet the mortality risks associated with hours of daily viewing over many years and whether increasing or decreasing viewing time affects mortality is unclear.
Bioprospecting (also known as biodiversity prospecting) is the exploration of natural sources for small molecules, macromolecules and biochemical and genetic information that could be developed into commercially valuable products for the…
The parents may be deceased, absent, or abusive. There may be substance abuse or mental illness in the biological home, or the parent may simply be unwilling to care for the child.

Observational studies have suggested that antioxidant nutrients may reduce cancer and overall mortality risks. However, most randomized trials have failed to demonstrate survival benefits.
Tea is the most popular non-alcoholic beverage worldwide and is one of the most important tree cash crops in East Africa. However, no comprehensive study has been carried out on the genetic structure and diversity of tea germplasm for this…
What genetic diversity levels were observed in East African tea germplasm?The study indicates a high genetic diversity (H S = 0.717) in East African tea germplasm, notably higher than reported in Japan and China.How did microsatellite markers improve the assessment of tea genetic diversity?The introduction of 23 nuclear SSR markers provided reliable genotyping, overcoming the limitations of dominant markers by ensuring locus specificity and high polymorphism.What breeding history is inferred from the genetic relationships among tea accessions?Results suggest a complex breeding history, with 71.88% of hybrids identified as F2 generations, predominantly involving C. assamica and C. sinensis.
Histones are far more than just the basic units of chromatin. Posttranslational modifications of histone tails have emerged as important regulatory mechanisms for diverse biological processes, including genome organization, gene expression…
