Peripheral nerves promote mouse bone marrow regeneration by activating b2 and b3 adrenergic receptor signaling, raising the possibility that non-selective b blockers could inhibit engraftment after hematopoietic cell transplants (HCTs). We observed no effect of b blockers on steady-state mouse hematopoiesis. However, mice treated with a non-selective b blocker (carvedilol), but not a b1-selective inhibitor (metoprolol), exhibited impaired hematopoietic regeneration after syngeneic or allogeneic HCTs.

Introduction: There is no standard protocol for management of organ preservation for orthotopic, life-sustaining cardiac xenotransplantation, particularly for hearts from pediatric sized donors. Standard techniques and solutions successful in human allotransplantation are not viable. We theorized that a solution commonly used in reparative cardiac surgery in human children would suffice by exploiting the advantages inherent to xenotransplantation, namely the ability to reduce organ ischemic times by co-locating the donor and recipient.

The immune composition of solid tumors is typically inferred from biomarkers, such as histologic and molecular classifications, somatic mutational burden, and PD-L1 expression. However, the extent to which these biomarkers predict the immune landscape in gastric adenocarcinoma-an aggressive cancer often linked to chronic inflammation-remains poorly understood. We leveraged high-dimensional spectral cytometry to generate a comprehensive single-cell immune landscape of tumors, normal tissue, and lymph nodes from patients in the Western Hemisphere with gastric adenocarcinoma.

Laboratory of Behavioral Neuroscience, National Institute on Aging, Intramural Research Program, Baltimore, MD, USA.

Background: Growth/differentiation factor-15 (GDF15) has been associated with dementia risk, yet its predictive value across cohorts and sub-population, as well as its relationship with endophenotypes relevant to dementia, remains unknown.

Methods: Using the Atherosclerosis Risk in Communities (ARIC) study as the discovery cohort, we examined the relationship between plasma GDF15 levels (SomaScan) and risk for incident all-cause dementia (ACD) in late-life (N=4,287, 7-year follow-up, M=75±5) and in midlife (N=11,595, 20-year follow-up, M=57±6). Utilizing the UK Biobank (UKB; replication cohort), we related plasma GDF15 (Olink) to incident ACD (N=35,673, 14-year follow-up, M=61±5), vascular dementia (VaD) and Alzheimer's disease dementia (AD).

The Mind Research Network, Albuquerque, NM, USA.

Background: In recent efforts to improve early identification, staging, and prediction of risk of persons at risk for vascular contributions to cognitive impairment and dementia (VCID) in relation with small vessel disease (SVD), the MarkVCID consortium has worked to identify and validate fluid- and imaging-based biomarkers for SVD associated with VCID. Free water (FW) measured derived from diffusion tensor imaging and one of the selected neuroimaging biomarker "kits", has been demonstrated to have excellent instrumental validity and to be a sensitive biomarker of cognitive performances. We sought to further examine FW clinical relevance by investigating whether FW predicts cognitive worsening over time.

Background: Peak-width of skeletonized mean diffusivity (PSMD) is an emerging biomarker of cerebral small vessel disease (cSVD)-related vascular contributions to cognitive impairment and dementia (VCID). Higher PSMD values reflect greater white matter microstructural damage, and prior research has related PSMD to sporadic and monogenic forms of cSVD and worse cognitive function. Therefore, we proposed PSMD as a risk stratification biomarker for VCID.

Introduction: The venous outflow profile (VOP) is a crucial yet often overlooked aspect affecting stroke outcomes. It plays a major role in the physiopathology of acute cerebral ischemia, as it accounts for both the upstream arterial collaterals and cerebral microperfusion. This enables it to circumvent the limitations of various arterial collateral evaluation systems, which often fail to consider impaired autoregulation and its impact on cerebral blood flow at the microcirculatory levels.
