Chemicals as therapeutics and investigational agents receive much attention in clinical research and applications recently. However, automated approaches to recognize and categorize the chemical entities in biomedical text are challenging because of the wide varieties of morphologies and nomenclature. We present here a hybrid text mining system that combines chemical lexicon and patterns for re...

background:  clavicle fractures are common and usually heal without complications. in this study, we evaluated the outcomes of non-operative versus operative management of displaced fractures.   methods:  in a prospective clinical trial study, sixty-five patients with displaced clavicle mid-shaft fractures were nonrandomly divided in two treatment groups. the first group underwent non-operative...

The aims of the present study were to assess the effects of maternal use of domestic chemicals during pregnancy on wheezing and lung function in children aged </=8.5 yrs and to explore the potential modifying effect of atopy. In the Avon Longitudinal Study of Parents and Children, a cohort study, a maternal composite household chemical exposure (CHCE) score was derived. Wheezing phenotypes from...

background: some studies have shown the possible role of protein‑energy malnutrition (pem) in persistence of endemic goiter in iodine replenished areas. the present study was conducted to assess the association between pem and goiter in schoolchildren of isfahan, iran. methods: in a cross‑sectional study using multistage cluster random‑sampling, 2331 schoolchildren with age ranged from 6‑13 yea...

Toxicity-based sediment quality guidelines (SQGs) are often used to assess the potential of sediment contamination to adversely affect benthic macrofauna, yet the correspondence of these guidelines to benthic community condition is poorly documented. This study compares the performance of 5 toxicity-based SQG approaches to a new benthos-based SQG approach relative to changes in benthic communit...

Background: In the UK and other developed countries the prevalence of asthma symptoms has increased in recent years. This is likely to be the result of increased exposure to environmental factors. A study was undertaken to investigate the association between maternal use of chemical based products in the prenatal period and patterns of wheeze in early childhood. Methods: In the population based...
