Clusterin induced by OPC phagocytosis blocks IL-9 secretion to inhibit myelination in a model of Alzheimer's disease.

Background: Variants in the gene have been identified as a risk factor for late-onset Alzheimer's disease and are linked to decreased white matter integrity in healthy adults. However, the specific role for clusterin in myelin maintenance in the context of Alzheimer's disease remains unclear.

Methods: We employed a combination of immunofluorescence and transmission electron microscopy techniques, primary culture of OPCs, and an animal model of Alzheimer's disease.

Trajectories of intrinsic connectivity one year post pediatric mild traumatic brain injury: Neural injury superimposed on neurodevelopment.

The developing brain undergoes rapid changes throughout middle childhood and adolescence. The disambiguation of long-term changes in intrinsic activity following pediatric mild traumatic brain injury (pmTBI) from typical development can therefore only be ascertained in longitudinal studies with large sample size and at least three serial assessments. A comprehensive clinical battery and resting-state fMRI data were collected approximately 1-week (N = 263; 8-18 years old), 4-months (N = 192) and 1-year (N = 153) post-injury, with identical visits in a large cohort (N = 228) of age- and sex-matched healthy controls (HC).

Floodplain forests drive fruit-eating fish diversity at the Amazon Basin-scale.

Unlike most rivers globally, nearly all lowland Amazonian rivers have unregulated flow, supporting seasonally flooded floodplain forests. Floodplain forests harbor a unique tree species assemblage adapted to flooding and specialized fauna, including fruit-eating fish that migrate seasonally into floodplains, favoring expansive floodplain areas. Frugivorous fish are forest-dependent fauna critical to forest regeneration via seed dispersal and support commercial and artisanal fisheries.

Fluid Distribution: Response to Intermittent Pneumatic Compression in People With and Without Primary Lymphedema.

Current understanding of changes in fluid distribution in response to the application of compression in primary lymphedema (PLE) is limited. This study measured fluid distribution before and after one application of standardized intermittent pneumatic compression (IPC) in the lower limbs of people with PLE, compared with those without lymphedema. High-frequency ultrasound (HFU) was used to measure dermal fluid, bioimpedance to measure segmental fluid, and percent water content (PWC) to measure fluid at specific anatomical points.

Forging new paths in the development of community mental health interventions for people with mental illness at risk of criminal legal system contact.

Background: Individuals with serious mental illness (SMI) have disproportionately high rates of criminal legal system involvement. For many, this becomes a repeated cycle of arrest and incarceration. Treatments that address symptoms of mental illness are a critical component of the continuum of services for people with SMI in the legal system; yet on their own, psychiatric treatments have not been successful at reducing criminal legal system involvement for this population.
