In the " Results " section of the abstract, " median, 12.1 (n = 179) vs. 6.8 (n = 332) adducts per 108 nucleotides, p < 0.001 " should have read " median, 12.1 (n = 179) vs. 6.8 (n = 332) adducts per 10 8 nucleotides, p < 0.001.

BACKGROUND Evidence for a relationship between trihalomethane (THM) or haloacetic acid (HAA) exposure and adverse fetal growth is inconsistent. Disinfection by-products exist as complex mixtures in water supplies, but THMs and HAAs have typically been examined separately. OBJECTIVES We investigated joint exposure at the individual level to THMs and HAAs(More)
Large-scale prospective cohort studies are invaluable in epidemiology, but they are increasingly difficult and costly to establish and follow-up. More efficient methods for recruitment, data collection and follow-up are essential if such studies are to remain feasible with limited public and research funds. Here, we discuss how these challenges were(More)
BACKGROUND Bulky DNA adducts reflect genotoxic exposures, have been associated with lower birth weight, and may predict cancer risk. OBJECTIVE We selected factors known or hypothesized to affect in utero adduct formation and repair and examined their associations with adduct levels in neonates. METHODS Pregnant women from Greece, Spain, England,(More)
The retention (binding to or association with the plant) of Escherichia coli by cut leaves and fruits after vigorous water washing was compared with that by sprouts. Retention by fruits and leaves was similar but differed from retention by sprouts in rate, effect of wounding and requirement for poly-β,1-6-N-acetyl-D-glucosamine. Escherichia coli was(More)
BACKGROUND Studies of disinfection by-products in drinking water and measures of adverse fetal growth have often been limited by exposure assessment lacking data on individual water use, and therefore failing to reflect individual variation in DBP exposure. METHODS Pregnant women recruited to the Born in Bradford cohort study completed a questionnaire(More)
The sensory role of the intact and ruptured anterior cruciate ligament was studied by the use of cortical evoked potentials during arthroscopy. This showed a response from the intact ligament in four patients that was reproducible. This response was consistent with those obtained from stimulation of the ipsilateral posterior tibial nerve. No response was(More)
