Unraveling the clinical-pathological correlations of subjects with isolated and mixed neurodegenerative processes in the National Alzheimer's Coordinating Center dataset.

Although Alzheimer disease neuropathologic change (ADNC) is the most common pathology underlying clinical dementia, the presence of multiple comorbid neuropathologies is increasingly being recognized as a major contributor to the worldwide dementia burden. We analyzed 1051 subjects with specific combinations of isolated and mixed pathologies and conducted multivariate logistic regression analysis on a cohort of 4624 cases with mixed pathologies to systematically explore the independent cognitive contributions of each pathology. Alzheimer disease neuropathologic change and limbic-predominant age-related TDP-43 encephalopathy neuropathologic change (LATE-NC) were both associated with a primary clinical diagnosis of Alzheimer disease (AD) and were characterized by an amnestic dementia phenotype, while only ADNC associated with logopenic variant primary progressive aphasia (PPA).

Rapid and Sensitive Chemical Analysis of Individual Picolitre Droplets by Mass Spectrometry.

Aerosol droplets are unique microcompartments containing microscopic amounts of material and exhibiting surprising chemical reactivity. Although a diverse set of tools exists to characterize the chemical composition of individual submicron particles in air, comparatively fewer approaches can chemically analyze individual, airborne picolitre droplets. We describe a novel approach for mass spectrometric analysis of individual aqueous picolitre droplets (∼2-180 pL volume) containing down to ∼1 pg analyte mass per droplet.

A conserved role for ALG10/ALG10B and the -glycosylation pathway in the sleep-epilepsy axis.

Congenital disorders of glycosylation (CDG) comprise a class of inborn errors of metabolism resulting from pathogenic variants in genes coding for enzymes involved in the asparagine-linked glycosylation of proteins. Unexpectedly to date, no CDG has been described for , encoding the alpha-1,2-glucosyltransferase catalyzing the final step of lipid-linked oligosaccharide biosynthesis. Genome-wide association studies (GWAS) of human traits in the UK Biobank revealed significant SNP associations with short sleep duration, reduced napping frequency, later sleep timing and evening diurnal preference as well as cardiac traits at a genomic locus containing a pair of paralogous enzymes and .

East London Project: a participatory mixed-method evaluation on how removing enforcement could affect sex workers' safety, health and access to services in East London.

Background: Sex workers' risk of violence and ill-health is shaped by their work environments, community and structural factors, including criminalisation.

Aim: We evaluated the impact of removing police enforcement on sex workers' safety, health and access to services.

Design: Mixed-methods participatory study comprising qualitative research, a prospective cohort study, mathematical modelling and routine data collation.

A necrotizing toxin enables Pseudomonas syringae infection across evolutionarily divergent plants.

The Pseudomonas syringae species complex harbors a diverse range of pathogenic bacteria that can infect hosts across the plant kingdom. However, much of our current understanding of P. syringae is centered on its infection of flowering plants.
