Abstract Accurate quantification of particulate phosphorus is critical for understanding biogeochemical processes in aquatic systems. Extra high‐temperature dry combustion at 800°C improves phosphorus recovery by ~ 11% compared to lower‐temperature methods.

Abstract Photosynthetic pigment fluorescence is commonly used in limnology and oceanography as a proxy for phytoplankton biomass. Fluorometry has been used to detect subsurface algal blooms, characterize dynamics of the deep chlorophyll layer, and to provide greater vertical resolution to phytoplankton monitoring.

Abstract Metabolism is a key property of lake ecosystem functioning, but logistical challenges make it difficult to estimate across remote regions. The steady‐state dissolved oxygen (DO) stable isotope method (18O method) estimates metabolism from discrete water samples and thus enables large‐scale surveys.

Abstract Background Visuospatial deficits in Parkinson's disease (PD) often precede dementia and complicate daily functioning. Alzheimer's disease (AD) pathology and α‐synuclein aggregation frequently co‐occur in PD, but their combined impact on cognition is unclear.

Focused Ultrasound for the Treatment of Circuit and Molecular Pathology in Parkinson's Disease
Abstract Focused ultrasound is rapidly emerging as a novel technology for the development of symptomatic therapies and supporting disease‐modifying treatments for Parkinson's disease (PD). At the forefront of this development is thermoablation using high‐intensity focused ultrasound, an incisionless treatment that has been extensively tested in ...

Exercise, exerkines, and muscle–brain crosstalk in Parkinson's disease
Abstract Parkinson's disease (PD) is a progressive neurodegenerative disorder with motor and non‐motor symptoms, driven by dopaminergic loss and α‐synuclein accumulation. Beyond neurodegeneration, growing evidence highlights skeletal muscle health as a key determinant of prognosis, with sarcopenia and frailty contributing to greater disability, fall ...
