Impaired adrenergic regulation of Kv channels underlies LC hyperactivity and early‐onset sleep disruption in AD‐like amyloidogenic mice

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Sleep–wake disturbances frequently occur at early stages of Alzheimer's disease (AD) and accelerate disease progression, but the underlying neural mechanisms are not fully understood. METHODS We examined sleep–wake behavior and locus coeruleus (LC) activity in young 5xFAD mice using electrophysiology and pharmacological approaches

On the Influence of Catalyst Mesopore Structure in the Catalytic Cracking of Polypropylene

open access: yesChemistryEurope, Volume 4, Issue 2, February 2026.
Catalytic cracking is a promising approach to convert polyolefin plastics into hydrocarbons. Herein, the effect of catalyst pore size in polypropylene cracking using amorphous silica–alumina with identical external acidity, but varying mesopore diameters and particle sizes, is isolated. Mesopore size has minimal effect on activity, indicating that high

Validation of on‐slide immunocytochemistry controls prepared from long‐term preserved prefixed cell suspensions

open access: yesCancer Cytopathology, Volume 134, Issue 2, February 2026.
Abstract Background On‐slide controls are essential for quality assurance in immunocytochemistry, yet their use in non–cell block cytology preparations remains a significant challenge. This study presents and evaluates a novel method for preparing on‐slide controls from long‐term prefixed cell suspensions, applicable to all types of cytology ...

Polygonal tepee structures of Arabia

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Tepee structures on Sheybarah Island form polygonal microbial cemented crusts in the intertidal. Radiocarbon dating suggests they formed in the Holocene and reflect minor sea‐level changes, highlighting their value as palaeoenvironmental indicators. Satellite surveys identified 126 polygonal features, including coral reefs that may have developed on ...

Differentiating hyperpycnal, hypopycnal and turbidity current deposits in late Quaternary glaciogenic mud

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
X‐ray CT and microscopic analysis of glaciogenic mud provide insight into the deposits of sediment‐laden density flows and reveal that strata comprise two microtextural motifs. The deposits of bottom‐hugging hyperpycnal flows and slope‐failure‐related turbidity currents are characterised by laterally continuous, sharply bounded silt‐rich and clay‐rich ...

Clinical Presentation of Shoulder‐Hand Syndrome: A Systematic Review

open access: yesEuropean Journal of Pain, Volume 30, Issue 2, February 2026.
ABSTRACT Background Shoulder‐hand syndrome (SHS) is a neurological disorder characterised by pain, loss of function, and trophic changes in the shoulder and hand of the affected limb. SHS shares a number of features with Complex Regional Pain Syndrome (CRPS).

Mechanochemical Treatment of Cellulose: A Strategy for Developing Functional Biocomposite Materials

open access: yesPolymer Engineering &Science, Volume 66, Issue 2, Page 662-688, February 2026.
Mechanochemistry as an integrated approach for combining fiber defibrillation, activation, surface functionalization, and cellulose‐based composite fabrication in a single or reduced number of steps. ABSTRACT Cellulose‐based biocomposites are attracting increasing scientific and industrial interest due to their sustainable origin, biodegradability, and
