Diversity of a chlorine-resistant Bacillus population isolated from a wastewater treatment station.

This paper describes the phenotypic and genotypic diversity of a Gram-positive, aerobic bacterial population isolated from the chlorine tank of a wastewater treatment plant. A total of 12 sporeforming, rod-shaped isolates were identified using 16S rRNA gene sequencing and biochemical tests. Pairwise genetic comparisons revealed the identity among sequences obtained from isolates varied from 92.

The paternal component of the "healthy migrant" effect: fathers' natality and infants' low birth weight.

This study examines the predictors of birth outcomes among women of European and African ancestry and considers the birthplace of the babies' fathers (foreign born vs. native born) as a protective factor. This is a secondary data analysis of 146,431 singleton births among women of European and African ancestry, both native-born and foreign-born, in a 21 birth hospital region of Central New York State from 1996 to 2003.

Ontogeny of renal P-glycoprotein expression in mice: correlation with digoxin renal clearance.

Digoxin is eliminated mainly by the kidney through glomerular filtration and P-glycoprotein (P-gp) mediated tubular secretion. Toddlers and young children require higher doses of digoxin per kilogram of bodyweight than adults, although the reasons for this have not been elucidated. We hypothesized there is an age-dependant increase in P-gp expression in young children.

Perinatal risks of untreated depression during pregnancy.

Objective: To review the literature on the perinatal risks involved in untreated depression during pregnancy.

Method: We searched Medline and medical texts for all studies pertaining to this area up to the end of April 2003. Key phrases entered were depression and pregnancy, depression and pregnancy outcome, and depression and untreated pregnancy.
