Extraction and Isolation of Bioactive Compounds From Malpighia glabra L. Leaves: In Vivo Investigation of the Leaf Extract Against Oxidative Stress and Inflammation Triggered by γ‐Radiation

Chemistry &Biodiversity, Volume 23, Issue 9, September 2026.
Malpighia glabra L. leaves extract, enriched with flavonoids and β‐isoarborinol, exhibits antioxidant and anti‐inflammatory activities that moderate γ‐radiation‐induced systemic and tissue harm. The extract preserves intestinal, hepatic, renal, splenic, and systemic integrity by reducing oxidative stress and inflammation, supporting its potential as a ...

Take my breath away: Defining the oxygen saturation threshold for fish cortisol stress response

Journal of Fish Biology, Volume 109, Issue 3, Page 1760-1770, September 2026.
Abstract Human activities are affecting the number, size and severity of hypoxic zones in aquatic ecosystems. As oxygen is one of the most important abiotic factors affecting fish biology, exposure to low levels of dissolved oxygen may lead to a reduction in fitness.

Radioprotection by Acclimatization to Cold [PDF]

Nature, 1963
THREE parallel series of irradiation have been run simultaneously to compare, in rats, the effects of acute and chronic whole-body irradiation by cobalt-60 γ-rays and to establish the radio-modifying effects of cold acclimatization in the latter condition1.

Tempol Protects Against Radiation Injury in the Submandibular Gland Through the β‐Catenin Signaling Pathway

Journal of Oral Pathology &Medicine, Volume 55, Issue 8, Page 895-905, September 2026.
ABSTRACT Background Radiation damage severely impacts salivary gland function and cell survival, especially in head and neck radiotherapy. Tempol (TPL), a free radical scavenger, has shown protective effects against radiation damage. This research aimed to investigate the protective effects of TPL on radiation‐induced damage in Hs917.T cells and the ...

Evolution of P‐wave Anisotropy as an Indicator of Pre‐failure Deformation in Shale

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Understanding the multiscale mechanical behavior of clay‐rich rocks is critical for assessing fault reactivation and the long‐term integrity of underground waste repositories. This study investigates the evolution of microdeformation in Tournemire's shale samples under compressive stress by integrating high‐resolution imaging (from an ...
