Do Commodity Prices and Energy Markets Drive Asymmetric Volatility in Biodiversity Finance?

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT This study examines symmetric and asymmetric volatility spillovers among biodiversity finance, commodity prices, and energy markets using daily data from 2019 to 2025. We apply the Diebold–Yilmaz time–domain connectedness model, Baruník–Křehlík frequency–domain decomposition, and an asymmetric spillover framework.

Primary Pulmonary Mesenchymal Neoplasm With EWSR1::CREM Fusion: Cytologic Findings and Molecular Diagnosis

open access: yesDiagnostic Cytopathology, EarlyView.
ABSTRACT Background Primary pulmonary mesenchymal neoplasms with EWSR1::CREM fusion are rare. These lesions are challenging to diagnose by morphology and immunohistochemistry alone. Case A 66‐year‐old woman (ex‐smoker) was found to have a 1.3‐cm right lower lobe lung nodule that had grown very slowly over a 9‐year period.

SPARCL1 and NT‐proBNP as biomarkers of right ventricular‐to‐pulmonary artery uncoupling in pulmonary hypertension

open access: yesESC Heart Failure, Volume 12, Issue 2, Page 1416-1426, April 2025.
Abstract Aims SPARCL1 was recently identified as a biomarker of right ventricular (RV) maladaptation in patients with pulmonary hypertension (PH), and N‐terminal pro‐brain natriuretic protein (NT‐proBNP) is an established biomarker of RV failure in PH. The present study investigated whether NT‐proBNP and SPARCL1 concentrations are associated with load ...

Vesicant burns: Is laser debridement ('lasablation') a viable method to accelerate wound healing? [PDF]

open access: yes, 2005
The vesicant agents, Lewisite and sulphur mustard were initially deployed as chemical weapons in the First World War at Ypres in 1917. These agents cause immediate blistering followed by deep dermal to full thickness burns and can be fatal in 1-3% (NATO ...

Reflex seizures and epilepsy surgery: A network approach case‐based exploration

open access: yesEpileptic Disorders, EarlyView.
Abstract Context Reflex seizures (RS) are defined by their consistent provocation by specific stimuli, encompassing a broad range from elementary sensory inputs to complex cognitive tasks. While RS are often encountered in clinical practice, their surgical management remains sparsely reported and poorly systematized.

From first seizure to specific antiseizure medication in Dravet syndrome: Quantifying delays in the DS'coverED study

open access: yesEpilepsia Open, EarlyView.
Abstract Objective Dravet syndrome (DS) is a rare early‐onset developmental and epileptic encephalopathy with persistent delays between seizure onset and diagnosis. The DS'coverED study aimed to characterize current diagnostic timelines by examining each step and its duration, identifying residual barriers, and actionable solutions to optimize the ...

Volatility Formation in Dairy Futures: Fundamentals, Public Information, and Processing Ambiguity

open access: yesJournal of Futures Markets, EarlyView.
ABSTRACT Class III milk futures cash‐settle to an administered price based on weekly component prices, creating a predictable within‐month flow of settlement‐relevant information. This paper studies drivers of cross‐month variation in realized volatility in this formula‐settled market.

Air Pollution Quinones Impair Intestinal Barrier Integrity and Endoplasmic Reticulum in Differentiated Caco‐2 Cells

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Particulate matter (PM) is a major global health threat, linked to millions of deaths annually. Beyond inhalation, PM components reach the gastrointestinal tract through the mucociliary escalator or contaminated food and water. Among PM's organic fraction, redox‐active quinones such as 1,2‐naphthoquinone (NQ) and 9,10‐phenanthrenequinone (PQ ...
