Sex Differences in Fall Frequency, Risk Factors, and Outcomes in Parkinson's Disease: A Cross‐Sectional Analysis

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Female sex is an independent fall risk factor in Parkinson's disease (PD), yet sex‐specific fall patterns remain unclear. Objectives To compare sex‐specific fall risk and outcomes across PD, prodromal alpha‐synucleinopathy (PAS), and healthy controls (HC); estimate fall frequency across PD progression; and assess how sex modifies ...

Comparison of traditional and molecular surveys of fish biodiversity in southern Te Wāhipounamu/Fiordland (Aotearoa/New Zealand)

open access: yesEnvironmental DNA
Effective management of biodiversity requires regular surveillance of multiple species. Analysis of environmental DNA (eDNA) by metabarcoding holds promise to achieve this relatively easily.

Association Between Plasma Phosphorylated Tau‐217 and Cognition in Parkinson's Disease

open access: yesMovement Disorders, EarlyView.
Abstract Background Alzheimer's disease (AD) co‐pathology contributes to dementia in PD, but its role in earlier cognitive impairment remains uncertain. Objective To determine if p‐tau217, a biomarker of early AD, is associated with cognitive impairment in PD.

Functionally cured chronic hepatitis B: A cure‐related occult HBV infection state

open access: yesmLife, EarlyView.
Abstract Occult HBV infection (OBI) is characterized by the presence of replication‐competent hepatitis B virus (HBV) DNA (covalently closed circular DNA [cccDNA] and/or relaxed circular DNA [rcDNA]) in the liver and/or HBV DNA in the blood, despite negative hepatitis B surface antigen (HBsAg) serology.

Spatio-temporal assessments of biodiversity in the high seas

open access: yesEndangered Species Research, 2014
Biological diversity is one of the most important measures for marine conservation in the high seas. However, data and tools to assess and quantify biodiversity in the high seas are still not well developed.

Modeling biomedical experimental processes with OBI [PDF]

open access: yesJournal of Biomedical Semantics, 2010
Experimental descriptions are typically stored as free text without using standardized terminology, creating challenges in comparison, reproduction and analysis. These difficulties impose limitations on data exchange and information retrieval.The Ontology for Biomedical Investigations (OBI), developed as a global, cross-community effort, provides a ...

Scalable low‐cost seabed landers: the missing link for sustained, integrated, long‐term observations in dynamic shallow seas

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Seabed landers, when equipped with a range of biotic and abiotic sensors, offer a non‐invasive and cost‐effective solution for ecosystem‐scale monitoring of Essential Biodiversity Variables (EBVs) and Essential Ocean Variables (EOVs) in dynamic shallow seas.
