Toxic and repellent effect of Zanthoxylum armatum (Sapindales:Rutacae) essential oil to Sitophilus zeamais (Coleoptera:Curculionidae)

Journal of the Saudi Society of Agricultural Sciences
The essential oil from Zanthoxylum armatum (Prickly ash) fruit was evaluated for its insecticidal properties against the Sitophilus zeamais (maize weevil) with different concentrations (10, 5, 2.5, 1.25, 0.62, 0.31, and 0.15%) in both a glass vial ...

Biomimetic Copper Nanoparticles Coated with ACE2‐Overexpressing Membranes for Selective SARS‐CoV‐2 Neutralization and Disinfection

Advanced Healthcare Materials, EarlyView.
By fusing ACE2‐overexpressing membrane‐integrated liposome (MIL) with copper nanoparticles, the biomimetic Cu@MIL nanostructures were created that directly hijack the SARS‐CoV‐2 entry pathway. These particles combine potent virus‐targeting precision with intrinsic antiviral activity, achieving rapid neutralization and disinfection.

Nb2C‐Reinforced Hydrogel Microneedle as Dual ROS‐Scavenging Platform to Promote Diabetic Wound Healing

Advanced Healthcare Materials, EarlyView.
An advanced microneedle patch integrating niobium carbide nanosheets and curcumin is engineered for diabetic wound healing. The system enables dual ROS scavenging and NIR‐enhanced antimicrobial activity, effectively rebalancing the oxidative microenvironment, promoting macrophage repolarization and angiogenesis, and accelerating full‐thickness wound ...

Oxygen Supply of Islets of Langerhans by Photosynthetically Active Microalgae in Bioprinted Co‐Cultures Maintains Their Function in a Hypoxic Environment

Advanced Healthcare Materials, EarlyView.
This study developed a bioprinted co‐culture system embedding rat pancreatic islets and Scenedesmus sp. microalgae spatially defined in close vicinity. Red light was found optimal to ensure microalgal photosynthesis while maintaining islet viability and functionality. A tailored co‐culture medium supported both cell types.

Persisters show heritable phenotype and generate bacterial heterogeneity and noise in protein expression [PDF]

, 2007
Persisters are a small subpopulation of bacteria that survive a lethal concentration of antibiotic without antibiotic resistance genes. Isolation of persisters from normally dividing population is considered difficult due to their slow growth, low ...

A Superhydrophobic 3D Cell Culture System Reveals the Mechanobiological Role of Cancer‐Associated Fibroblasts in Prostate Cancer Metastasis

Advanced Healthcare Materials, EarlyView.
A superhydrophobic 3D cell culture platform enables rapid and consistent formation of heterotypic tumor–stroma clusters, and reveals how physiological shear conditions influence metastatic signaling. Mechanical stimulation of cancer‐associated fibroblasts promotes sustained cytokine secretion and survival‐promoting pathways, showing how multicellular ...
