Structural basis of THC analog activity at the Cannabinoid 1 receptor.

Tetrahydrocannabinol (THC) is the principal psychoactive compound derived from the cannabis plant Cannabis sativa and approved for emetic conditions, appetite stimulation and sleep apnea relief. THC's psychoactive actions are mediated primarily by the cannabinoid receptor CB. Here, we determine the cryo-EM structure of HU210, a THC analog and widely used tool compound, bound to CB and its primary transducer, G.

DHODH Inhibition Suppresses and Inhibits the Growth of Medulloblastoma in a Novel In Vivo Zebrafish Model.

Background/objectives: Medulloblastoma (MB) is the most common high-grade paediatric brain tumour, with group 3 MB patients having the worst prognosis. A high prevalence of group 3 tumours shows overexpression of the oncogene, making it a potential therapeutic target. However, attempts to directly inhibit have so far demonstrated limited success.

Evaluation of the Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP) for People Living With Cognitive Impairment and Dementia in Care Homes.

Background: Major knowledge and practice gaps exist in aged care home services to support independence of older people with dementia. This research evaluates an adaptation of a community-based rehabilitation model for care homes, namely Interdisciplinary Care Home-bAsed Reablement Program (I-CHARP), by examining whether (and, if so, how) I-CHARP produces its intended effects and how this programme can be practicably implemented, sustained and scaled up across care homes in Australia.

Methods: I-CHARP is a 4-month bio-behavioural-environmental rehabilitation model of care, integrated in care home services, supported through the deployment of an implementation strategy, the Research Enabled Aged Care Homes (REACH) network.

A Modified Cell-Penetrating Peptide Enhances Insulin and Oxytocin Delivery across an RPMI 2650 Nasal Epithelial Cell Barrier In Vitro.

Unlabelled: Peptide-based treatments represent an expanding area and require innovative approaches to enhance bioavailability. Combination with cell-penetrating peptides (CPPs) is an attractive strategy to improve non-invasive delivery across nasal epithelial barriers for systemic and direct nose-to-brain transport. We previously developed a modified CPP system termed Glycosaminoglycan-binding Enhanced Transduction (GET) that improves insulin delivery across gastrointestinal epithelium.
