The bacteriophage j pM promoter is required for maintenance of the j prophage in Escherichia coli, as it facilitates transcription of the cI gene, encoding the j repressor (CI). CI levels are maintained through a transcriptional feedback mechanism whereby CI can serve as an activator or a repressor of pM. CI activates pM through cooperative binding to the OR1 and OR2 sites within the OR operato...

In 2014, a fatal infection with Legionella pneumophila serogroup 1 occurred in a neonate after a water birth. The death highlighted the need for infection control education, client awareness, and standardization of cleaning procedures in Texas midwife facilities.

the present paper deals with development of a simulation model for the performance evaluation of feed water system of a thermal power plant using markov birth-death process and probabilistic approach. in present paper, the feed water system consists of four subsystems. after drawing transition diagram for feed water system, differential equations are developed and then solved recursively using ...

AbstractObjective: This systematic review aimed to investigate theeffect of water intake during pregnancy on infant birthweight.Methods: A comprehensive search was conducted usingthe keywords "water intake," "dehydration," "pregnancy,""outcome," "hydration," "birth weight," and outcome"in databases such as "SCOPUS," "EBSCO," "PUBMED,""COCHRANE," through "Google Search." MeSH headings"pregnancy"...

BACKGROUND Previous studies suggest that elevated exposure to drinking water disinfection by-products (DBPs)--in particular, total trihalomethanes (TTHMs)--may lead to fetal growth restriction. We examined the effects of exposure to TTHMs, haloacetic acids, and total organic halide on the probability of delivering a small-for-gestational-age (SGA) infant and on birth weight at term. METHODS W...

Hypernatraemia in very low birth weight babies has been well documented and is usually attributable to excessive insensible water loss. We report a case in which, despite a peak serum sodium concentration of 204 mmol/l, the baby survived without morbidity. Treatment was simply to increase the intake of free water in Dextrose.

BACKGROUND Atrazine is a herbicide used extensively worldwide. Bioassays have shown that it is embryotoxic and embryolethal. Evidence of adverse reproductive outcomes from exposure in the general population is sparse. AIMS To evaluate the association between atrazine levels in municipal drinking water and the following adverse reproductive outcomes: increased risk of preterm delivery, low bir...

BACKGROUND Previous studies have suggested that elevated exposure to disinfection by-products (DBPs) in drinking water during gestation may result in adverse birth outcomes. However, the findings of these studies remain inconclusive. OBJECTIVE The purpose of our study was to examine the association between blood biomarkers of late pregnancy exposure to trihalomethanes (THMs) in drinking water...
