Prenatal exposure to the herbicide linuron, a weak androgen receptor antagonist, has been shown to perturb androgen-dependent male rat reproductive development as evidenced by slight decreases in anogenital distance (AGD), increased retention of areolae/nipples, and induction of epididymal malformations in combination with testicular atrophy in the adult rat over dose levels ranging from 12.5 t...

Pacifiers, also known as soothers, dummies and artificial teats are as rooted in history as they are in controversy. Pacifiers made of clay, silver, pearl or coral, and sugar teats have been described, some dating back to over thousands of years [1][2]. Pacifier use is still widespread in today’s culture, and a recent Canadian trial reports up to 84% of infants use one at least some of the time...

On dairy farms with a small number of livestock, it is not always profitable to use expensive high-performance machines and equipment. Here, more rational easy-to-maintain means mechanization, which significantly facilitate the work farmer, requiring low operating costs. milk production, in turn, closely related method keeping livestock. This non-binding box method, which, as domestic foreign e...

Background X-linked hypohidrotic ectodermal dysplasia (XLHED), the most common form of ectodermal dysplasia, is caused by mutations in the gene EDA. While only affected men develop the full-blown clinical picture, females who are heterozygous for an EDA mutation often also show symptoms such as hypodontia, hypotrichosis and hypohidrosis. These women may also suffer from malformations of the mam...

The objective of this research was to identify chromosomal regions harboring QTL affecting reproduction in pigs. A three-generation resource population was developed by crossing low-indexing pigs from a randomly selected control line (C) with high-indexing pigs of a line selected for increased index of ovulation rate and embryonic survival (I). Differences between Lines I and C at Generation 10...
