Parental origin of transgene modulates amyloid-β plaque burden in the 5xFAD mouse model of Alzheimer's disease.

In Alzheimer's disease (AD) research, the 5xFAD mouse model is commonly used as a heterozygote crossed with other genetic models to study AD pathology. We investigated whether the parental origin of the 5xFAD transgene affects plaque deposition. Using quantitative light-sheet microscopy, we found that paternal inheritance of the transgene led to a 2-fold higher plaque burden compared with maternal inheritance, a finding consistent across multiple 5xFAD colonies.

Associations of daily step count with all-cause mortality and cardiovascular mortality in hypertensive US adults: a cohort study from NHANES 2005-2006.

Background: The health benefits of physical activity, including walking, are well-established, but the relationship between daily step count and mortality in hypertensive populations remains underexplored. This study investigates the association between daily step count and both all-cause and cardiovascular mortality in hypertensive American adults.

Methods: We used data from the National Health and Nutrition Examination Survey 2005-2006, including 1,629 hypertensive participants with accelerometer-measured step counts.

Anti-Syndecan 2 Antibody Treatment Reduces Edema Formation and Inflammation of Murine Laser-Induced CNV.

Purpose: Alteration of visual acuity in wet age-related macular degeneration (AMD) is mostly driven by vascular endothelial growth factor A (VEGF-A)-induced edema from leaky newly forming blood vessels below the retina layers. To date, all therapies aimed at alleviation of this process have relied on inhibition of VEGF-A activity. Although effective in preventing vascular leak and edema, this approach also leads to the loss of normal vasculature and multiple related side effects.

Vascular endothelial growth factor-D improves lung vascular integrity during acute lung injury.

Disorders in pulmonary vascular integrity are a prominent feature in many lung diseases. Paracrine signaling is highly enriched in the lung and plays a crucial role in regulating vascular homeostasis. However, the specific local cell-cell crosstalk signals that maintain pulmonary microvascular stability in adult animals and humans remain largely unexplored.

Electronic and paper delivery of parent proxy and children's report of two scar-specific patient-reported outcome measures (Brisbane Burn Scar Impact Profile and Patient and Observer Scar Assessment Scale): An equivalence study.

Introduction: The Brisbane Burn Scar Impact Profile (BBSIP) and the Patient and Observer Scar Assessment Scale (POSAS) are used in burn scar assessment to quantify patient health-related quality of life (HR-QoL). These questionnaires were developed using pen-and-paper delivery methods; however, there is a push towards electronic delivery of these questionnaires in both clinical practice and research. Equivalence testing is required to ensure that validity of these paper questionnaires is maintained electronically.
