Recent research has indicated that the pro-inflammatory cytokines, particularly interleukin-1beta (IL-1beta), can affect learning and memory. We injected male Sprague-Dawley rats with IL-1beta (1.0, 3.0, or 6.0 microg/kg, i.p.) or saline vehicle, 24h before a single 4-h session of leverpress escape/avoidance conditioning. No effect of IL-1beta at any dose was observed in the number of escape responses across the 4-h session. However, subjects treated with the two lower doses (1.0 and 3.0 microg/kg) of IL-1beta performed more avoidance responses during the final hour of the 4-h session than the other two groups. Subjects treated with the highest dose of IL-1beta (6.0 microg/kg) did not differ from controls. Results are discussed in terms of the possible mechanisms behind the IL-1beta-induced enhancement of learning, as well as the observed dose-response relationship.

Vertebrate brain function is particularly sensitive to the effects of hypoxia, with even brief periods of oxygen deprivation causing significant brain damage and impaired cognitive abilities. This study is the first to investigate the cognitive consequences of hypoxia in fish, specifically induced by exhaustive exercise and air exposure, conditions commonly encountered during catch-and-release (C&R) practices in recreational fishing. Angling exerts substantial pressure on inland fish populations, underscoring the need for sustainable practices like C&R.

Background: Cocaine Use Disorder (CUD) remains a significant problem in the United States, with high rates of relapse and no present FDA-approved treatment. The acetylcholine neurotransmitter system, specifically through modulation of muscarinic acetylcholine receptor (mAChR) function, has shown promise as a therapeutic target for multiple aspects of CUD. Enhancement of the M mAChR subtype via positive allosteric modulation has been shown to inhibit the behavioral and neurochemical effects of cocaine across several rodent models of CUD.

Background: Prior research has shown that primary care clinicians (PCPs) spend a large portion of clinic visits on tasks within the electronic health record (EHR). However, no time allocation studies have been done in the Veterans Health Administration (VHA) and little is known about EHR time spent during virtual visits.
Objective: To estimate the proportion of clinician time spent working within the EHR during primary care visits at VHA clinics.

The pharmacokinetics and pharmacodynamics (PK/PD) of vancomycin change during HD, increasing the risk of subtherapeutic concentrations. The aim of this study was to evaluate during and after the conventional and prolonged hemodialysis sessions to identify the possible risk of the patient remaining without adequate antimicrobial coverage during therapy. Randomized, non-blind clinical trial, including critically ill adults with septic AKI on conventional (4 h) and prolonged HD (6 and 10 h) and using vancomycin for at least 72 h.

Aim: We investigated the effect that increased physical activity (PA) sessions had on the blood pressure of school-aged children who were overweight and obese.
Methods: This Polish pilot, prospective study followed up 148 children from six elementary schools from 10 to 12 years of age. They were divided into two groups, based on parental preferences.
