Embryonic and fetal development of the collared peccary (Pecari tajacu)

Animal Reproduction Science, 2019
El momento relativo de los principales eventos de desarrollo fetal en las especies determina el grado de desarrollo fetal al nacer, que varía a lo largo de un gradiente de tener rasgos altriciales y precoces. Los resultados de este estudio permiten describir importantes desarrollos fetales en el pecarí de collar (Pecari tajacu) utilizando datos de 118 ...

Effects of organolead compounds on rat embryonic and fetal development

Toxicology and Applied Pharmacology, 1972
Abstract Tetraethyl lead (TEL) and tetramethyl lead (TML) and trimethyl lead chloride (TriML), were found to be essentially nonteratogenic in Sprague-Dawley rats. Oral doses of TEL (7.5, 15, or 30 mg/kg), TML (40, 80, 112, or 160 mg/kg) and TriML (15, 30, or 38 mg/kg) were administered as 3 divided doses during early organogenesis (days 9, 10, and 11)

Central vagal sensory and motor connections: human embryonic and fetal development

Autonomic Neuroscience, 2004
The embryonic and fetal development of the nuclear components and pathways of vagal sensorimotor circuits in the human has been studied using Nissl staining and carbocyanine dye tracing techniques. Eight fetal brains ranging from 8 to 28 weeks of development had DiI (1,1'-dioctadecyl-3,3,3',3' tetramethylindocarbocyanine perchlorate) inserted into ...

Effects of chlorophyllin on mouse embryonic and fetal development in vivo

Teratogenesis, Carcinogenesis, and Mutagenesis, 2002
AbstractChlorophyllin (CHL) has proven that there is antimutagenic and anticarcinogenic activity in several organisms without causing lethal effects. However, there is no information about its effects when it is administered in gestation. In the present study, we assessed possible effects of CHL when it was administered to CD‐1 mice on the 8th day of ...

Impacts of arginine nutrition on embryonic and fetal development in mammals

Amino Acids, 2013
Embryonic loss and intrauterine growth restriction (IUGR) are significant problems in humans and other animals. Results from studies involving pigs and sheep have indicated that limited uterine capacity and placental insufficiency are major factors contributing to suboptimal reproduction in mammals.

Embryonic and fetal development of the red brocket deer (Mazama americana)

Theriogenology, 2019
The red brocket deer (Mazama americana), a medium-sized Neotropical ungulate, is one of the most hunted mammals in the Amazon. This study analyzes the intrauterine development in the red brocket deer through the description of the external and internal morphology in one embryo and 38 fetuses collected from animals hunted for subsistence in the Amazon ...

Embryonic and fetal development of the white-lipped peccary (Tayassu pecari)

Theriogenology, 2018
The white-lipped peccary (Tayassu pecari) is an endangered large-sized Neotropical ungulate that is one of the most hunted mammals in the Amazon. Here, we used two embryos and 102 white-lipped peccary fetuses originated from animals hunted for subsistence in the Peruvian and Brazilian Amazon to describe the intrauterine development of external and ...

Hepatic Drug-Metabolizing Enzymes during Embryonic and Fetal Development

1983
Twenty or thirty years ago, it was believed that all drugs (and other environmental pollutants) were “toxic”, or pharmacologically active, in their parent (non-metabolized) form. The function of all drug-metabolizing enzymes was therefore regarded as detoxication, i.e. to “inactivate” the active parent drug.
