Kinetic Isotope Effects of the Enzymatic Transformation of γ-Hexachlorocyclohexane by the Lindane Dehydrochlorinase Variants LinA1 and LinA2.

Environmental Science and Technology, 2019
Compound-specific isotope analysis (CSIA) can provide insights into the natural attenuation processes of hexachlorocyclohexanes (HCHs), an important class of persistent organic pollutants.

Hippocampal degeneration is associated with GFAP levels in individuals with vascular dementia independently of amyloidosis

Alzheimer's &Dementia, Volume 20, Issue S9, December 2024.
Abstract Background Vascular cognitive impairment/dementia (VD) is the second most prevalent cause of dementia following Alzheimer's disease (AD). VD is characterized by the progression of white matter hyperintensity burden (WMH) and associated neurodegeneration.

Confounding factors to Alzheimer's disease plasma biomarkers in patients from a memory‐clinic cohort

Alzheimer's &Dementia, Volume 20, Issue S9, December 2024.
Abstract Background Blood‐based biomarkers for Alzheimer’s disease (AD) are increasingly prevalent and accessible beyond research environments. Consequently, it is crucial to determine whether confounding factors, particularly highly prevalent comorbidities, influence the levels of these blood biomarkers, thereby refining their clinical interpretation.

Physician Preferences in Using Novel Digital Devices for the Management of Atrial Fibrillation—A DAS‐CAM III Survey

Clinical Cardiology, Volume 47, Issue 12, December 2024.
This survey of > 500 cardiologists and electrophysiologists outlines physician's preferences in using novel digital rhythm devices in the management of atrial fibrillation. The survey consisted of 22 case‐based questions. Currently, physicians rarely use photoplethysmography‐based devices. However, the uptake of ECG‐based devices is high, especially in

A Simple Risk Assesment Method for Continental Waters, Based on Screening Contaminants of Emerging Concern

Advanced Sustainable Systems, Volume 8, Issue 9, September 2024.
The water status of the Mero‐Barcés rivers watershed shows to be very good, above average for European Rivers, but the obtained results pose some uncertainty about the potential environmental effects of the CECs concentrations found, mostly in the order of ppt.

Carbon‐Embedded Pt Alloy Cluster Catalysts for Proton Exchange Membrane Fuel Cells

Advanced Energy Materials, Volume 14, Issue 29, August 2, 2024.
Carbon‐embedded Pt alloy cluster catalysts, including PtFe, PtCo, and PtNi, are developed to minimize Pt usage in proton exchange membrane fuel cells (PEMFCs). The Pt alloy clusters are stabilized within a carbon matrix, while still allowing gaseous oxygen transfer.

Dysregulation of Cytokine Response in Canadian First Nations Communities: Is There an Association with Persistent Organic Pollutant Levels? [PDF]

, 2012
In vitro and animal studies report that some persistent organic pollutants (POPs) trigger the secretion of proinflammatory cytokines. Whether POP exposure is associated with a dysregulation of cytokine response remains to be investigated in humans.

Forest defoliation by an invasive outbreak insect: Catastrophic consequences for a charismatic mega moth

Ecology and Evolution, Volume 14, Issue 8, August 2024.
The drivers underlying worldwide declines in insect abundance and diversity are multiple, complex, and incompletely known. We use a natural experiment to test the hypothesis that forest defoliation by an invasive outbreak insect compromises the fitness of a native insect via damage‐induced increases in toxicity of the forest canopy. We demonstrate that
