Exposing newborn mice to general anesthetic disrupts brain development
“early postnatal mice exposed to isoflurane – a standard and widely used inhaled general anesthetic agent – leads to chronic, abnormal activation of the mTOR pathway, a signaling system critical […]
Banned chemicals pass through umbilical cord from mother to baby
“Trace amounts of flame retardants, banned in the U.S. for more than a decade, are still being passed through umbilical cord blood from mothers to their babies, according to new […]
Profound perturbation induced by triclosan exposure in mouse gut microbiome
“Triclosan exposure has a profound impact on the mouse gut microbiome by inducing perturbations at both compositional and functional levels. To our best knowledge, this is the first evidence regarding […]
Exposure to specific toxins and nutrients correlates with autism risk
“Our study suggests that metal toxicant uptake and essential element deficiency during specific developmental windows increases ASD risk and severity, supporting the hypothesis of systemic elemental dysregulation in ASD. Independent […]
Common pesticide damages honey bee’s ability to fly
“Our results provide the first demonstration that field-realistic exposure to this pesticide alone, in otherwise healthy colonies, can alter the ability of bees to fly, specifically impairing flight distance, duration […]
Antibiotic Use In Young Mice Linked To Inflammatory Disease
“Disrupting the early development of a healthy gut microbiome can do serious — yet reversible — damage, a study finds.”
Antibiotic ‘link to bowel cancer precursor’
“People who take antibiotics for a long time are more likely to develop growths on the bowel which can be a precursor to cancer, a study suggests.”
Low-dose penicillin in early life induces long-term behavioral changes (mouse study)
“low-dose penicillin taken late in pregnancy and in early life of mice offspring, changes behaviour and the balance of microbes in the gut. While these studies have been performed in […]
Exposure to common flame retardants may raise the risk of papillary thyroid cancer
“Some flame retardants used in many home products appear to be associated with the most common type of thyroid cancer, papillary thyroid cancer (PTC), according to a new study”
