Differential involvement of hippocampal angiotensin 1 receptors in learning and memory processes in bulbectomized rats [PDF]

open access: yes, 2016
There is conflicting evidence regarding the effect of AT1 receptor antagonists on learning and memory processes. The effects of angiotensin II and losartan administration into CA1 hippocampal area on the avoidance performance in olfactory bulbectomized ...

Skeletogenic Expression of Integrin Alpha, Talin and Npnt Genes and Npnt Role in Sea Urchin Skeletogenesis

open access: yesJournal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
Three integrin alpha genes and the cytoskeletal adaptor talin are enriched in sea urchin skeletogenic cells during early skeletogenesis. The extracellular matrix protein nephronectin (Npnt) is expressed in the skeletogenic cells throughout skeletogenesis and supports normal skeletal growth, highlighting a potential role for cell–matrix interactions in ...

Age‐Dependent Finite Element Analysis of Microneedle Penetration into Human Skin: Influence of Insertion Velocity, and Microneedle's Geometry and Material

open access: yesMacromolecular Materials and Engineering, EarlyView.
This study evaluates the combined effects of microneedle material, geometry, and insertion velocity on insertion force, considering the critical impact of age‐related variations in human skin. The results show that insertion force increases with age due to higher skin stiffness.

A Comprehensive Study of Quantum Dots: Ranging From Synthesis to Applications in Electrochemical Biosensors in the Detection of Biomolecules, Gastrointestinal Diseases, and Electrophysiology

open access: yesNano Select, EarlyView.
Quantum dots (QDs) typically refer to extremely small semiconductor particles, often no larger than 10 nm. The development of efficient biosensors for the sensitive and selective detection of biomolecules is essential for fundamental research in analytical chemistry, biomedicine, clinical diagnosis, and electrophysiology.

Molecular mechanism of ATP‐binding cassette transporter‐mediated insecticide resistance

open access: yesNew Plant Protection, EarlyView.
Advances in functional genomics (RNAi and CRISPR/Cas9) and artificial intelligence‐driven structure prediction (e.g., AlphaFold) are elucidating how ATP‐binding cassette transporters mediate insecticide resistance to both synthetic chemicals and Bacillus thuringiensis toxins.
