Automated detection and analysis of subdural hematomas using a machine learning algorithm.

Objective: Machine learning algorithms have shown groundbreaking results in neuroimaging. Herein, the authors evaluate the performance of a newly developed convolutional neural network (CNN) to detect and quantify the thickness, volume, and midline shift (MLS) of subdural hematoma (SDH) from noncontrast head CT (NCHCT).

Methods: NCHCT studies performed for the evaluation of head trauma in consecutive patients between July 2018 and April 2021 at a single institution were retrospectively identified.

Metformin Prevents Low-dose Isoproterenol-induced Cardiac Dilatation and Systolic Dysfunction in Male Sprague Dawley Rats.

Myocardial metabolic abnormalities are well-recognized alterations in chronic heart failure, effects that may contribute to progressive cardiac dysfunction. However, whether metabolic alterations in-part mediate their deleterious effects by modifying the chronic impact of excess low-dose sympathetic stimulation on cardiac chamber dilatation is uncertain. We therefore aimed to determine the effect of metformin administration on cardiac function and mitochondrial architectural changes in a rat model of chronic sympathetic-induced left ventricular (LV) remodeling and systolic dysfunction [daily subcutaneous isoproterenol (ISO) injection at a low dose of 0.

The potential developmental programming effect of oral curcumin on the bone health and plasma total osteocalcin of male and female rats fed a high-fructose diet during suckling and post weaning.

We investigated the effect of oral curcumin, on bone health of rats fed a high-fructose diet. Suckling pups (males = 65, females = 63) were gavage with 0.5% DMSO, curcumin (500 mg/kg), fructose (20%, w/v) or a combination of curcumin and fructose daily from postnatal days 6 to 21.

Glu of the GnRH receptor is part of the conserved G protein-coupled receptor structure and does not form a salt-bridge with Lys.

GnRH receptor mutations, GluLys and GluAsp, cause congenital hypogonadotropic hypogonadism. The Glu side-chain has been proposed to form an intramolecular salt-bridge with Lys, but conserved intramolecular interaction networks in G protein-coupled receptor crystal structures predict that it interacts with Ser and Trp. We investigated interhelical interactions of Glu that stabilise GnRH receptor folding using functional analyses and computational modelling of mutant receptors.

Brewer's yeast is a potent inducer of fever, sickness behavior and inflammation within the brain.

Brewer's yeast, derived from the yeast species Saccharomyces cerevisiae (S. cerevisiae), is commonly used for inducing pyrexia in pharmacological studies screening antipyretics in rats. Despite its widespread use, the peripheral and central inflammatory response associated with Brewer's yeast-induced fever and sickness behavior in rats has not been investigated.
