Response of green reflectance continuum removal index to the xanthophyll de-epoxidation cycle in Norway spruce needles [PDF]

open access: yes, 2017
A dedicated field experiment was conducted to investigate the response of a green reflectance continuum removal-based optical index, called area under the curve normalized to maximal band depth between 511nm and 557nm (ANMB511-557), to light-induced ...

Spider Silk–Integrated Biomimetic Micropillars With Dual Adhesion for Improved Wound Hemostasis and Healing

open access: yesAdvanced Materials Technologies, Volume 11, Issue 3, 5 February 2026.
The patch mimics the dual physicochemical adhesion mechanisms of gecko toe micropillars and spider silk proteins, enabling strong interfacial bonding via partially cured micropillars. Its facile fabrication allows customization for precision medicine, while its motion responsiveness offers potential for real‐time wound monitoring.

Spectroscopic Methods of Edible Flower Authentication and Quality Control for Food Applications

open access: yeseFood, Volume 7, Issue 1, February 2026.
The global demand for edible flowers has increased. Issues such as incorrect species identification, flower product adulteration, contamination, and quality degradation necessitate the application of proper methods for authenticating and controlling the product's quality.

Protective Effect and Mechanism of Rosiglitazone in α‐amanitin‐induced Hepatotoxicity Via Activation of PPAR‐γ/Nrf2 Signaling Pathway

open access: yesJournal of Biochemical and Molecular Toxicology, Volume 40, Issue 2, February 2026.
ABSTRACT α‐amanitin (α‐AMA), the primary lethal toxin of amanita, primarily targets the liver with a high toxicity and a low lethal dose. As the precise mechanism of intoxication is unclear, and specific antidotes are lacking, α‐AMA‐induced liver injury has a high mortality rate.

Oxidative Stress: Molecular Mechanisms, Diseases, and Therapeutic Targets

open access: yesMedComm, Volume 7, Issue 2, February 2026.
Oxidative stress occurs when the reactive oxygen species (ROS) production overwhelms the ROS scavenging, which lead to genomic instability, epigenetic regulation, proteostasis imbalance, and lipid peroxidation, subsequently causing the occurrence and development of numerous diseases. ABSTRACT Although the physiological level of reactive oxygen species (

A new lab facility for measuring bidirectional reflectance/emittance distribution functions of soils and canopies [PDF]

open access: yes
Recently, a laboratory measurement facility has been realized for assessing the anisotropic reflectance and emittance behaviour of soils, leaves and small canopies under controlled illumination conditions.

Colours of urban selection: carotenoid‐based signals reveal divergent urban/rural evolutionary trajectories in two closely related passerines

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Urbanisation is a major driver of environmental change, reshaping ecological and evolutionary processes. Urban‐driven phenotypic differences are increasingly documented, but the underlying role of selection is still understudied. One pattern is the consistent reduction of carotenoid‐based plumage pigmentation in city birds.
