Social and nonsocial environmental loss have differential effects on ventral hippocampus-dependent behavior and inhibitory synaptic markers in adult male mice.

In humans, psychological loss, whether social or nonsocial, can lead to clinical depression, anxiety disorders, and social memory impairments. Researchers have modeled combined social and nonsocial loss in rodents by transitioning them from social, enriched environments (EE) to individual housing, affecting behaviors related to avoidance, stress coping, and cognitive function. However, it remains unclear if these effects are driven by social or nonsocial loss.

Serum amikacin concentrations in dogs with naturally occurring open wounds treated with topical amikacin in carboxymethylcellulose hydrogel.

Objective: To quantify serum amikacin concentrations in dogs undergoing wound management with topical amikacin (45 mg/mL) 3% carboxymethylcellulose hydrogel.

Study Design: Prospective clinical study.

Sample Population: Eleven client-owned dogs.

Pharmacodynamics of 2 dosages of orally administered esomeprazole in client-owned, healthy dogs: A prospective, crossover study.

Background: Esomeprazole use is increasing in dogs, but the gastrointestinal adverse events associated with q12h dosing necessitate pharmacodynamic evaluation of a reduced dose and frequency of administration.

Objectives: To compare the efficacy of 2 doses of (q24h) esomeprazole in raising intragastric pH in dogs.

Animals: Nine healthy, client-owned dogs, >20 kg.

Hepatic retinol dehydrogenase 11 dampens stress associated with the maintenance of cellular cholesterol levels.

Objective: Dysregulation of hepatic cholesterol metabolism can contribute to elevated circulating cholesterol levels, which is a significant risk factor for cardiovascular disease. Cholesterol homeostasis in mammalian cells is tightly regulated by an integrated network of transcriptional and post-transcriptional signalling pathways. Whilst prior studies have identified many of the central regulators of these pathways, the extended supporting networks remain to be fully elucidated.
