Cryopreservation of primary neonatal rat oligodendrocytes and recapitulation of oligodendrocyte characteristics.

Introduction: , primary rat oligodendrocytes (OLs) are widely used for research on OL development, physiology, and pathophysiology in demyelinating diseases such as multiple sclerosis. Primary culture methods for OLs from rats have been developed and improved over time, but there are still multiple aspects in which efficiency can be boosted.

Methods: To make use of excess oligodendrocyte progenitor cells (OPCs) from primary cultures, a cryopreservation process utilizing a commercially available serum-free cryopreservation medium was established to passage and freeze OPCs at -80°C for later use.

A-kinase anchor protein 12 promotes oligodendrogenesis and cognitive recovery in carbon monoxide therapy for traumatic brain injury.

Therapeutic drug development for central nervous system injuries, such as traumatic brain injury (TBI), presents significant challenges. TBI results in primary mechanical damage followed by secondary injury, leading to cognitive dysfunction and memory loss. Our recent study demonstrated the potential of carbon monoxide-releasing molecules (CORMs) to improve TBI recovery by enhancing neurogenesis.

A Survey of Wild Indigenous Orchid Populations in Western Australia Reveals Spillover of Exotic Viruses.

is a terrestrial orchid endemic to southwestern Australia. The virus status of has not been studied. Eighty-three samples from 16 populations were collected, and sequencing was used to identify RNA viruses from them.

Aspirin modulates inflammatory biomarkers in patients with subcortical silent brain infarcts.

Introduction: This study aimed to identify differences in the levels of inflammation-related biomarkers between patients with subcortical silent brain infarcts (SBIs) and healthy controls. We also evaluated the effect of aspirin on the subcortical SBI inflammatory processes.

Methods: Consecutive patients diagnosed with subcortical SBIs without a history of acute stroke were included.

Postural instability and gait disturbance are associated with abnormal stereopsis in Parkinson's disease.

Background: Visual dysfunction, including abnormal stereopsis, is a significant non-motor symptom in Parkinson's disease (PD) that can reduce quality of life and appears early in the disease. Abnormal stereopsis is associated with worsening of bradykinesia and freezing of gait, though the exact pathways linking stereopsis to motor symptoms remain unclear. Furthermore, in PD patients, the pedunculopontine nucleus and laterodorsal tegmental complex play an active role in sensorimotor control, and these areas provide cholinergic projections.
