THC Disrupts Rat Fear Memory via Sex-Specific Microglial and Receptor Pathways
In male rats, THC requires microglial recruitment and dual receptor signaling, while female effects depend on the estrous cycle and CB1.
Gamma Knife Surgery Provides Durable Control of Vestibular Schwannoma
A 30-year study shows true tumor progression is rare after 10 years, supporting reduced imaging for patients stable at the 5-year mark.
Child Maltreatment Linked to Systemic Homeostatic Dysregulation
Recent trauma in children may disrupt physiological stability and delay development in males rather than accelerating biological aging.
Propofol Reduces Long-Term Water Contamination Compared to Sevoflurane
A modeling study finds sevoflurane leads to irreversible accumulation of trifluoroacetic acid while propofol residues remain biodegradable.
Lumateperone Leads Efficacy While Aripiprazole Shows Best Acceptability in Depression
A meta-analysis of 10,962 patients quantifies the trade-offs between symptom reduction and treatment adherence for adjunctive antipsychotics.
BRAF V600E Mutation Predicts Early Recurrence in Rathke Cleft Cysts
A retrospective analysis of 383 sellar lesions suggests BRAF-positive cysts behave like papillary craniopharyngiomas and require reclassification.
