Exposure to prothioconazole induces developmental toxicity and cardiovascular effects on zebrafish embryo.

Chemosphere, 2020
Prothioconazole is a fungicide that has been widely used in general agriculture and livestock husbandry. This study evaluated the acute toxicity of prothioconazole to zebrafish embryos by assessing their hatching rate and malformation when exposed to ...

Developmental Toxicity of a Neonicotinoid Insecticide, Acetamiprid to Zebrafish Embryos.

Journal of Agricultural and Food Chemistry, 2019
Agricultural use of neonicotinoid insecticides is increasing worldwide, posing a risk to nontarget organisms. The present study investigated developmental toxicity of a widely used neonicotinoid, acetamiprid, to zebrafish embryos.

Commentary on the Role of Maternal Toxicity on Developmental Toxicity

Birth Defects Research Part B: Developmental and Reproductive Toxicology, 2012
Maternal mammalian toxicity impacts prenatal development, with general systemic maternal toxicity, from reduced weight gain to morbidity, causative for reduced fetal weights/litter and increased fetal variations (especially skeletal)/litter, but not, in the author's opinion, for increased fetal malformations, reduced litter sizes or full litter losses.

Low level of polystyrene microplastics decreases early developmental toxicity of phenanthrene on marine medaka (Oryzias melastigma).

Journal of Hazardous Materials, 2019
Microplastics (MPs) have become global environmental concern. However, the effects of environmental concentrations of MPs, singly or in combination with organic pollutants, on the early development of marine fish remain unclear. In this study, fertilized

Developmental Toxicity of Engineered Nanomaterials

2017
Abstract Engineering of nanosized particles provides new material properties due to large surface area, design and control of particle shape, and surface coatings. Toxicological properties of nanoparticles may therefore differ from bulk material. Developmental toxicity of nanoparticles may occur due to “traditional” toxicity, relating to specific ...

The developmental toxicity of uranium in mice

Toxicology, 1989
To evaluate the developmental toxicity of uranium, 5 groups of 20 pregnant Swiss mice were given by gavage daily doses of 0, 5, 10, 25 and 50 mg/kg of uranyl acetate dihydrate on gestational days 6-15. Cesarean sections were performed on all females on gestation day 18. Fetuses were examined for external, visceral, and skeletal abnormalities.

Developmental toxicity of copper in marine medaka (Oryzias melastigma) embryos and larvae.

Chemosphere, 2020
Copper as developmental toxicants have been reported extensively in freshwater fish, however, the sublethal and chronic toxic effects of Cu to the early life stages of marine fish are not clear. Embryo (3-5 hpf) and newly hatched larvae of marine medaka (

Isoliquiritigenin triggers developmental toxicity and oxidative stress-mediated apoptosis in zebrafish embryos/larvae via Nrf2-HO1/JNK-ERK/mitochondrion pathway.

Chemosphere, 2019
Isoliquiritigenin (ISL) is an emerging natural flavonoid found in the roots of licorice, exhibits antioxidant, anti-cancer, anti-inflammatory, anti-allergic, cardioprotective, hepatoprotective and neuroprotective properties. However, the effect of ISL in

Developmental toxicity of cesium in the mouse

General Pharmacology: The Vascular System, 1994
1. Maternal intake of 1 mEq CsCl in drinking water at conception until weaning the offspring mice resulted in certain maternal mediated neonatal and developmental toxicity. 2. Initial reduction in body and brain weights were determined in male offspring due to maternal exposure to Cs salt before they attained the control levels. 3.
