Cattle foraging on milkweed: Intra‐seasonal herbivory shifts and implications for monarch butterfly conservation

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
Abstract Managing milkweed (Asclepias spp.) is of high conservation concern due to its association with monarch butterflies (Danaus plexippus L.), which are proposed for listing under the Endangered Species Act. To counteract monarch declines, conservation goals aim to establish ≥1.6 billion nonagricultural milkweed stems within the Midwestern United ...

Genetic Variation in Chemical Defence Affects Protection of an Herbivorous Insect Against Predation

open access: yesMolecular Ecology, Volume 35, Issue 9, May 2026.
ABSTRACT Genetic variation contributes to intraspecific differences in the chemical defence in many insect species, yet the underlying genetic mechanisms remain poorly understood. The horseradish flea beetle, Phyllotreta armoraciae, sequesters glucosinolates from its horseradish host plant and activates them using endogenous myrosinase enzymes.

Cardenolide-Induced Lysosomal Membrane Permeabilization Demonstrates Therapeutic Benefits in Experimental Human Non-Small Cell Lung Cancers

open access: yesNeoplasia: An International Journal for Oncology Research, 2006
Non-small cell lung cancers (NSCLCs) are the leading cause of cancer deaths in most developed countries. Targeting heat shock protein 70 (Hsp70) expression and function, together with the induction of lysosomal membrane permeabilization (LMP), could ...

Green Synthesis of Metal Oxide Nanoparticles Using Plant Extracts: Applications in Catalysis and Biomedicine

open access: yesNano Select, Volume 7, Issue 3, March 2026.
ABSTRACT The green synthesis of metal oxide nanoparticles (MONPs) using plant‐based resources has gained significant traction as an environmentally benign, cost‐effective, and scalable alternative to traditional chemical and physical methods. This review comprehensively explores the plant‐mediated synthesis routes for a variety of MONPs, including CuO,

Ouabain‐induced hypertension in rats: Mechanisms, variability and translational implications

open access: yesExperimental Physiology, Volume 111, Issue 3, Page 653-673, 1 March 2026.
Abstract Ouabain‐induced hypertension is a multifactorial and condition‐dependent phenomenon involving coordinated actions across vascular, renal and central nervous system pathways. At the vascular level, ouabain inhibits Na⁺/K⁺‐ATPase, particularly the α2‐isoform, leading to elevated intracellular Ca2⁺, enhanced vasoconstriction and structural ...
