Cortical Acetylcholine Response to Deep Brain Stimulation of the Basal Forebrain in Mice.

Deep brain stimulation (DBS) using electrical stimulation of neuronal tissue in the basal forebrain to enhance release of the neurotransmitter acetylcholine is under consideration to improve executive function in patients with dementia. While some small studies indicate a positive response in the clinical setting, the relationship between DBS and acetylcholine pharmacokinetics is incompletely understood. We examined the cortical acetylcholine response to different stimulation parameters of the basal forebrain.

Seroprevalence of SARS-CoV-2 in wet market workers in Dhaka, Bangladesh in 2022.

Objectives: We assessed the transmission of SARS-CoV-2 and vaccine receipt in a representative sample of wet market workers in a highly dense, low-income setting. Wet markets are key in many Asian settings, including Dhaka, Bangladesh, for fresh food, including animal protein.

Methods: During early 2022, we assessed the prevalence of anti-SARS-CoV-2 antibodies in a random sample of poultry and vegetable workers in 15 wet markets, and investigated associations with socio-demographic characteristics and COVID-19 vaccination.

Enhanced Tumor Control and Hearing Loss Prevention Achieved with Combined Immune Checkpoint Inhibitor and Anti-VEGF Therapy in Vestibular Schwannoma Model.

Background: -related schwannomatosis ( -SWN) is a debilitating condition that calls for robust treatment options. The defining feature of -SWN is the presence of bilateral vestibular schwannomas (VSs), which grow over time and can result in irreversible sensorineural hearing loss, significantly affecting the quality of life for those affected. At present, there are no FDA-approved medications specifically for treating VS or related hearing loss.

of chickens: the changing face of an old foe.

The cost of coccidiosis in chickens fluctuates considerably, peaking in 2022.Three new species can infect chickens and escape current vaccines. infection exerts wide-ranging effects on enteric microbiota.

Divers treated in Townsville, Australia: worse symptoms lead to poorer outcomes.

Introduction: Hyperbaric oxygen treatment (HBOT) is considered definitive treatment for decompression illness. Delay to HBOT may be due to dive site remoteness and limited facility availability. Review of cases may help identify factors contributing to clinical outcomes.
