The significance of gestational age in evaluating the antepartal cardiotokogram (author's transl)

The influence of gestational age on the probable meaning of features in the antepartal CTG which are not clearly pathological was investigated in 232 births in 1973/74. The umbilical artery pH was significantly lower among premature infants exhibiting abnormal, than among those exhibiting normal CTG patterns. No similar difference was found in term or overdue births. The clinical diagnosis of neonatal condition using the Apgar scheme confirmed biochemical findings: The frequency of depressed babies is in turn clearly higher in cases with abnormal antepartal CTG patterns. It is assumed that the reason for this is the higher sensitivity of premature babies to haemodynamic disturbances. Thus, it follows that premature babies exhibiting antepartal patterns which are not completely normal require close observation.

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.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
