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 ...

Sample Preparation For Microinjection

open access: yes, 2014
### General Comments The microscopic tip of the glass microcapillary has an inner diameter between 0.2 and 1 µm . This capillary is back loaded with the substance to be transferred into the cells cultured for microinjection. Typical substances include purified antibodies, DNA, RNA, peptides, or oligonucleotides.

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.

Thermoelectrical regulation of microinjection moulds [PDF]

open access: yes, 2010
Microinjection is one of the major replication techniques for producing low cost micro parts. The small scale of the microinjection processes presents different challenges from those usually encountered in conventional injection moulding.

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.

Do Nucleating Agents or Processing Methods Affect the Thermal Transport in RacoPP?

open access: yesJournal of Polymer Science, EarlyView.
The addition of 1,3,5‐benzenetrisamide as a nucleating agent and processing via injection molding or compression molding of propylene‐ethylene random copolymer (racoPP) can impact the crystallinity and orientation of polypropylene lamellae, whereas the thermal diffusivity of racoPP exhibits remarkable resilience to these changes. ABSTRACT Polypropylene
