Retrospective analysis of ethnic/racial disparities and excess vascular mortality associated with the COVID-19 pandemic.

Unlabelled: The Sars coronavirus 2019 (COVID-19) pandemic has resulted in increased morbidity and mortality; however, there is limited understanding of how excess mortality is distributed among different racial and ethnic subgroups and vascular diseases.

Methods: We conducted a retrospective, cross-sectional study design using data from the United States (US) Center for Disease Control (CDC) Wide Ranging Online Data for Epidemiologic Research (Wonder) database. The database contains death certificate information for all US residents by cause of death as ascertained by the treating physician.

Assessment of brain-derived extracellular vesicle enrichment for blood biomarker analysis in age-related neurodegenerative diseases: An international overview.

Introduction: Brain-derived extracellular vesicles (BEVs) in blood allows for minimally-invasive investigations of central nervous system (CNS) -specific markers of age-related neurodegenerative diseases (NDDs). Polymer-based EV- and immunoprecipitation (IP)-based BEV-enrichment protocols from blood have gained popularity. We systematically investigated protocol consistency across studies, and determined CNS-specificity of proteins associated with these protocols.

Dissection of the Temporofrontal Extreme Capsule Fasciculus Using Diffusion MRI Tractography and Association with Lexical Retrieval.

The well-known arcuate fasciculus that connects the posterior superior temporal region with the language production region in the ventrolateral frontal cortex constitutes the classic peri-Sylvian dorsal stream of language. A second temporofrontal white matter tract connects ventrally the anterior to intermediate lateral temporal cortex with frontal areas via the extreme capsule. This temporofrontal extreme capsule fasciculus (TFexcF) constitutes the ventral stream of language processing.
