Effects of sub-lethal teratogen exposure during larval development on egg laying and egg quality in adult Caenorhabditis elegans

open access: yesF1000Research, 2016
Background: Acute high dose exposure to teratogenic chemicals alters the proper development of an embryo leading to infertility, impaired fecundity, and few viable offspring.

Teratogenicity and Teratogenic Factors

open access: yesMOJ Anatomy & Physiology, 2017
Teratology is the science that investigates the congenital malformations and their causes Intrauterine exposure to a toxicant particularly in early pregnancy induces embryonic and fetal changes ranging from none up to malformations and stillbirths The teratogenic agents include some viral spirochetal and protozoal infections physical agents as ionizing

A method for human teratogen detection by geometrically confined cell differentiation and migration

open access: yesScientific Reports, 2015
Unintended exposure to teratogenic compounds can lead to various birth defects; however current animal-based testing is limited by time, cost and high inter-species variability.

Shh signaling in limb bud ectoderm: Potential role in teratogen‐induced postaxial ectrodactyly

open access: yes, 2005
A variety of teratogens induce the loss of postaxial forelimb structures when administered during mid-gestation to the mouse. Previous studies demonstrated that teratogen exposure is associated with a reduction in zone of polarizing activity (ZPA ...

Anticonvulsants and Chromatin-Genes Expression: A Systems Biology Investigation

open access: yesFrontiers in Neuroscience, 2020
Embryofetal development is a critical process that needs a strict epigenetic control, however, perturbations in this balance might lead to the occurrence of congenital anomalies.

Avidin is evolutionarily conserved in fish but dispensable for development and resistance against Streptococcus agalactiae in zebrafish

open access: yesFEBS Open Bio, EarlyView.
The presence of biotin‐binding avidin proteins in fish and their biological significance are poorly characterized. We cataloged fish avidins and demonstrate that they are widely present and evolutionarily conserved. We created avd knockout zebrafish and show that zebavidin is dispensable for development and that resistance of avd knockout embryos in ...

Specific Association of Teratogen and Toxicant Metals in Hair of Newborns with Congenital Birth Defects or Developmentally Premature Birth in a Cohort of Couples with Documented Parental Exposure to Military Attacks: Observational Study at Al Shifa Hospital, Gaza, Palestine

open access: yesInternational Journal of Environmental Research and Public Health, 2014
This study was undertaken in Gaza, Palestine, in a cohort of babies born in 2011. Hair samples of newborns were analyzed for metal load by DRC-ICP-MS.

How physicians perceive and utilize information from a teratogen information service: The Motherisk Program [PDF]

open access: yes, 2004
Background Teratogen information services have been developed around the world to disseminate information regarding the safety of maternal exposures during pregnancy. The Motherisk Program in Toronto, Canada, fields thousands of these inquiries per year.
