The Impact of the COVID-19 Pandemic on the Epidemiology and Management Strategies of Forearm Fractures in Children-a Retrospective Study.

Background: The COVID-19 pandemic has had a considerable influence over the management strategies in pediatric trauma all over the world. We are making a comparative assessment of all pediatric forearm fracture presentations in a tertiary center in Romania in a pre-pandemic year 2019 (NPG) versus a pandemic year 2021 (PG).

Material And Methods: We retrospectively compared the epidemiological, the anatomopathological, and the management features of forearm fractures for the two years.

Molecular and genetic characterization of sex-linked orange coat color in the domestic cat.

The mutation in domestic cats causes variegated patches of reddish/yellow hair and is a defining signature of random X-inactivation in female tortoiseshell and calico cats. Unlike the situation for most coat color genes, there is no apparent homolog for in other mammals. We show that the is caused by a 5 kb deletion that leads to ectopic and melanocyte-specific expression of the ( ) gene.

VEGFC Overexpression in Kidney Progenitor Cells Is a Model of Renal Lymphangiectasia-Brief Report.

Background: Lymphangiogenesis is believed to be a protective response in the setting of multiple forms of kidney injury and mitigates the progression of interstitial fibrosis. To augment this protective response, promoting kidney lymphangiogenesis is being investigated as a potential treatment to slow the progression of kidney disease. As injury-related lymphangiogenesis is driven by signaling from the receptor VEGFR3 (vascular endothelial growth factor receptor 3) in response to the cognate growth factor VEGF (vascular endothelial growth factor)-C released by tubular epithelial cells, this signaling pathway is a candidate for future kidney therapeutics.

Distinct Chrna5 mutations link excessive alcohol use to types I/II vulnerability profiles and IPN GABAergic neurons.

Genome wide association and animal studies have implicated genetic variations in CHRNΑ5, encoding the α5 subunit-containing nicotinic acetylcholine receptors (α5*nAChRs), as a risk factor for developing alcohol use disorders (AUDs). To understand how α5*nAChR mutations may influence alcohol (EtOH) drinking behavior, we used a two-bottle choice procedure with intermittent access to alcohol in male and female transgenic mice expressing either the highly frequent human single nucleotide polymorphism (α5SNP/rs16969968) or a deletion of the Chrna5 gene (α5KO). AUDs-related preconsommatory traits (anxiety, sensation-seeking and impulsivity) were assessed with a battery of relevant tasks (elevated-plus maze, novel place preference and step-down inhibitory avoidance).
