Article Synopsis
  • The generation of neurons in the central nervous system involves radial glia, which are mitotic progenitors that rapidly proliferate to form a dense neurepithelium and produce different neuronal sub-types.
  • Molecular mechanisms behind this process are not well understood, but a family of enzymes called GDE proteins, including GDE6, play a role in neural development.
  • Research shows that overexpression of GDE6 leads to neural tube hyperplasia, abnormal neurepithelium growth, and a decrease in the production of motor neurons, indicating its important role in regulating radial glia and neurogenesis alongside GDE2.

Monkeypox is an emerging threat to humans since a new outbreak in May 2022. It is hypothesised that increasing the immunologically naive population after the cessation of the smallpox vaccination campaign in the 1980s is one of the leading causes of it. A literature search was conducted using different electronic databases including MEDLINE (through PubMed), SCOPUS, Web of Science, Cochrane library, and EMBASE for relevant studies.

Objective: As apoE(-/-) and LDL-Receptor(-/-) mice are commonly used in atherosclerosis research; our objective was to point out the differences in HDL metabolism between mice and humans regarding the roles of apoE and LDLR.

Methods: We examined HDL particles obtained from wild type (WT), LDLR(-/-), and apoE(-/-) mice, as well as from normal, homozygous familial hypercholesterolemic (FH), and apoE-deficient human subjects by 2-dimensional non-denaturing PAGE followed by immunoblot and image analysis.

Results: In WT mice, the majority of apoA-I was in large (9.

Background: In response to growth in cardiac imaging, medical societies have published appropriateness use criteria (AUC) and payers have introduced preauthorization mandates, largely through radiology benefits managers (RBM). The correlation of algorithms used to determine preauthorization with the AUC is unknown. In addition, studies applying the 2007 AUC for transthoracic echocardiography revealed that many echocardiograms could not be classified.

We compared adherence to appropriateness criteria for transthoracic echocardiography in a Veterans Administration Medical Center (VAMC) and an academic practice and, within the VAMC, between physicians and mid-level providers. We reviewed 201 outpatient echocardiograms performed in the laboratory of an academic practice and 424 outpatient and inpatient studies performed at a VAMC. Echocardiographic examinations requested for indications addressed in the criteria were considered classified, and those for indications not addressed were considered unclassified.
