Maternal and fetal ethanol pharmacokinetics and cardiovascular responses in near-term pregnant sheep

Canadian Journal of Physiology and Pharmacology

The disposition and cardiovascular effects of ethanol were studied in near-term pregnant sheep and their fetuses after intravenous infusions either to the mother or the fetus. Placental transfer of ethanol from mother to fetus was rapid, but transfer from the fetal to maternal circulation was impaired when ethanol was administered directly to the fetus. Plasma clearance of ethanol was similar from the mother and fetus in utero. In the maternal infusion experiments, both maternal and fetal heart rate increased with plasma ethanol concentration. However, in the fetal infusion experiments, both maternal and fetal heart rate increased with plasma ethanol concentration. However, in the fetal infusion experiments, fetal heart rate was inversely related to plasma ethanol concentrations while maternal mean arterial blood pressure increased with maternal plasma ethanol concentration. Further studies in neonatal lambs are needed to determine if ethanol has adverse effects on hemodynamics when the neonate is separated from its protective intrauterine environment.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

Social Learning

Social learning involves learning new behaviors through observation, imitation and modeling. Follow this feed to stay up to date on the latest research.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
