Influence of cognitive impairment and race on plasma p-Tau in two diverse cohorts.

Introduction: Factors influencing plasma Alzheimer's disease (AD) biomarkers remain incompletely understood. Here we evaluated Fujirebio plasma p-Tau in two diverse cohorts among whom 91% underwent cerebrospinal fluid (CSF) analysis.

Methods: Non-Hispanic White (NHW, n = 113), Black/African American (B/AA, n = 66), and Chinese American (ChA, n = 38) participants recruited from two universities were included.

Girls play basketball too? A study of the mechanisms of traditional social gender consciousness on female participation in contact leisure sports.

Background: With the development of women's sports, the mechanism of barriers to women's leisure sports participation has attracted extensive attention from the academic community. Despite its significant impact, there are few empirical studies on intra-personal barriers. Consequently, a structural equation model was established to examine the relationships between traditional social gender awareness, gender bias, gender stereotypes, and barriers to participation in leisure sports.

Factors associated with attitudes toward research MRI in older Asian Americans.

Introduction: South Asian (SA) and East Asian (EA) older adults represent the fastest-growing racial/ethnic groups of Americans at risk for dementia. While recruiting older SA adults into a brain health study, we encountered unexpected hesitancy toward structural brain magnetic resonance imaging (MRI) analysis and stigmatizing attitudes related to internal locus of control (LoC) for future dementia risks. We hypothesized that support for MRI-related research was influenced by these attitudes as well as personal MRI experience, perceived MRI safety, and concerns for personal risk for future dementia/stroke.

Too much information? Asian Americans' preferences for incidental brain MRI findings.

Introduction: South Asian (SA) and East Asian (EA) older adults represent the fastest growing group of Americans at risk for dementia, but their participation in aging and dementia research has been limited. While recruiting healthy SA older adults into a brain health study, we encountered unexpected hesitancy towards structural brain MRI analysis along with some stigmatizing attitudes related to internal locus of control (LoC) for future dementia risks. We hypothesized that support for MRI-related research was influenced by these attitudes as well as one's own MRI experience, perceived MRI safety, and concerns for one's own risks for future dementia/stroke.

Pulse wave velocity and age- and gender-dependent aortic wall hardening in fowl.

Before sexual maturation, chickens (Gallus gallus) show high blood pressure (BP) and neointimal plaques in the lower abdominal aortae (AbA). We investigated age/sex-related changes in pulse wave velocity (PWV), elastin, collagen, and protein levels in AbA, and cardiac morphology to determine whether PWV increases during incremental increases in BP of maturing fowl, while arterial stiffness becomes dominant with aging. PWV (m/s) was significantly greater in male chicks (6-7 weeks, 9.
