Adenosine A receptors (AARs) have shown promising therapeutic properties despite their controversial role in modulating stroke outcome. However, the temporal evolution of cerebral AARs density after cerebral ischemia and its subsequent neuroinflammatory response have been scarcely explored. In this study, the expression of AARs after transient middle cerebral artery occlusion (MCAO) was evaluated in rats by positron emission tomography (PET) with [C]SCH442416 and immunohistochemistry (IHC).

Memory formation involves a complex interplay of molecular and cellular processes, including synaptic plasticity mechanisms such as long-term potentiation (LTP) and long-term depression (LTD). These processes rely on activity-dependent gene expression and local protein synthesis at synapses. A central unresolved question in neuroscience is how memories can be stably maintained over time, despite the transient nature of the proteins involved in their initial encoding.

Introduction: Rhinovirus (RV) is the leading cause of exacerbations of lung disease. A sensory neuronal model, derived from human dental pulp stem cells and differentiated into peripheral neuronal equivalents (PNEs), was used to examine RV's effects on airway sensory nerves. We investigated whether RV can directly infect and alter PNEs or whether it exerts effects indirectly via the release of mediators from infected epithelial cells.

Early postoperative seizures, defined as occurring within 7 days after surgery, are a significant complication that occurs following neurosurgical procedures involving cerebral manipulation. As a result, short-term antiseizure medication is typically administered in Japan despite the lack of consensus regarding its prophylactic use. Perampanel hydrate, an α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid receptor antagonist, was recently introduced in an intravenous formulation in Japan, providing new potential for early postoperative seizures prevention during the perioperative period.

Intratympanic (IT) delivery of dexamethasone (DEX) is widely used for treating inner ear disorders; however, its therapeutic efficacy is limited by poor permeability of the round window membrane (RWM). This study aimed to evaluate and compare the efficacy and safety of three pharmacological agents-histamine (HIS), 3% hypertonic saline (3% HS), and sodium caprate (SC)-as adjuvants for enhancing RWM permeability and improving IT-DEX delivery in a murine model. Following IT administration of each permeability enhancer followed by DEX injection, perilymph DEX concentrations were measured using ultra-high-performance liquid chromatography, and DEX receptor expression in the organ of Corti was assessed by immunofluorescence.
