low-dose exposure antibiotics unveiled zebrafish gut
2019/11/15
An antibiotic commonly found at low concentrations in the environment can have major impacts on gut bacteria, according to a study by a team of researchers at the University of Oregon, published in th...
Harms of nighttime light exposure passed to offspring
Harms nighttime light exposure passed offspring
2017/4/27
Animals can pass the damaging effects of nighttime light exposure to their offspring, a new study has found, adding to a growing body of evidence that there’s a health cost to our increasingly illumin...
Towards a cross-border exposure model for the Earthquake Model Central Asia
Seismic Risk Exposure Sampling Remote Sensing
2015/8/17
This work provides an insight into the development of the first harmonized exposure model for Central Asia. The model was derived in the frame of the Earthquake Model Central Asia (EMCA) project, whic...

Southern Exposure: New Paleoclimate Insights From Southern Ocean and Antarctic Margin Sediments
Southern Ocean Antarctic Margin Sediments
2015/7/15
Much of what is known about the evolution of Antarctica's cryosphere in the geologic past is derived from ice-distal deep-sea sedimentary records. Recent advances in drilling technology and climate pr...
Effect of Soyabean Isoflavones Exposure on Onset of Puberty, Serum Hormone Concentration and Gene Expression in Hypothalamus, Pituitary Gland and Ovary of Female Bama Miniature Pigs
Soybean Isoflavones Puberty Puberty Delay Bama Miniature Pigs
2016/5/19
This study was to investigate the effect of soyabean isoflavones (SIF) on onset of puberty, serum hormone concentration, and gene expression in hypothalamus, pituitary and ovary of female Bama miniatu...
Tadpole model links drug exposure to autism-like effects
Tadpole model links drug exposure autism-like
2015/3/4
Research suggests that fetal exposure to chemicals or drugs can cause neurological problems. Babies whose mothers take the epilepsy drug valproic acid (VPA) during pregnancy, for example, appear to ha...
Refinement of a model for evaluating the population exposure in an urban area
population exposure urban area

A mathematical model is presented for the determination of human exposure to ambient air pollution in an
urban area; the model is a refined version of a previously developed mathematical model ...
Identification of genes affected by fetal alcohol exposure during brain development
The fetus alcohol mental retardation injury mechanism the brain genes and animal models
2014/12/11
Fetal alcohol exposure is the leading known cause of mental retardation in the western world. However, the mechanisms underlying alcohol-induced damage in fetal brain are largely unknown. The goal of ...
Prostaglandin E₂ promotes recovery of hematopoietic stem and progenitor cells after radiation exposure
hematopoiesis radiomitigation radiation
2015/5/21
The hematopoietic system is highly proliferative, making hematopoietic stem and progenitor cells (HSPC) sensitive to radiation damage. Total body irradiation and chemotherapy, as well as the risk of r...

Fetal alcohol spectrum disorders (FASD) is the leading neurodevelopment deficit in children born to women who drink alcohol during pregnancy. The hippocampus and cortex are among brain regions vulnera...
Modeling wind waves and wave exposure of nearshore zones in medium-sized lakes
Modeling wind waves wave exposure nearshore zones medium-sized lakes
2014/4/2
We determine wind-wave properties and estimate the wave exposure along the entire shore of Lake U¨berlingen,a subbasin of Lake Constance, using a third-generation spectral wave model (SWAN), and compa...
