BACKGROUND Largehead Atractylodes Rhizome (LAR) is the most commonly used Chinese medicine to prevent early pregnancy loss due to threatened miscarriage. However, its safety profile during pregnancy is still not available. Here we aimed to identify the potential adverse effects of LAR on embryo-fetal development as well as prenatal and post-natal growth. METHODS Pregnant mice, rats and rabbit...

Neonicotinoids are pesticides used worldwide. They bind to insect nicotinic acetylcholine receptors (nAChRs) with high affinity. We previously reported that clothianidin (CTD), one of the latest neonicotinoids, reduced antioxidant expression and induced germ cell death in the adult testis of vertebrates. Here, we investigated the male reproductive toxicity of prenatal and early postnatal exposu...

Organic mercury compounds were first described in the 1800s, with fatal cases of methylmercury poisoning reported in 1865. Early reports described a distinct set of symptoms of methylmercury toxicity, including altered sensation in the face and extremities, tunnel vision, deafness , loss of coordination, and impaired speech. Nearly a century later, against a backdrop of widespread environmental...

OBJECTIVE The purpose of this study was to examine the differences between women who reported current and past physical or sexual abuse and those who did not in terms of mean total prenatal weight change, the odds for inadequate prenatal gain, and the odds for excessive prenatal gain. METHODS This study used a matched retrospective cohort design. Data were from the charts of 578 clients of an...

 Harlequin ichthyosis is a rare and the most severe form of congenital ichthyosis. Although prenatal diagnosis is difficult for this disorder, recently, this obstacle has markedly improved with the use of DNA-based prenatal diagnosis. Here in, we presented a neonate with harlequin ichthyosis born by assisted reproductive technology (ART). In this case, the diagnosis of harlequin ichth...

the acute and sub-acute toxicity of safranal were studied in rat and mice within 2 and 21 days after exposure, respectively. for subacute toxicity, changes in weight as well as biochemical, hematological and pathological parameters were studied. the intraperitoneal ld50 values of safranal were 1.48 ml/kg in male mice, 1.88 ml/kg in female mice and 1.50 ml/kg in male rats. oral ld50 values were ...

Results of tests to evaluate chemicals for potential adverse effects on fetal development inform product development decisions, as well as inform the public and other stakeholders. Regulatory agencies also use results to support acceptance and product labeling. Currently accepted in vivo testing protocols used to generate these data are timeand resource-intensive and require the use of animals....
