Oppositely Charged Homopolypeptides Form Ordered Helix Assemblies With Hierarchical Structure

open access: yesSmall, EarlyView.
Hexagaonal and square assembly of polyarginine alfa‐helices formed in highly ordered polyarginine/polyaspartic acid complexes. The helices exhibit additional periodic staggering along their helical axis. ABSTRACT Oppositely charged polyelectrolytes are known to form polyelectrolyte complexes.

Rapid Fabrication of Sub‐100 µm Microstructures In Situ via Femtosecond Laser for Correlative Imaging of Rare Cells

open access: yesSmall, EarlyView.
In this work, a femtosecond (fs) laser processing strategy is demonstrated for rapid and targeted fabrication of 3D sub‐100‐µm microstructures on resin‐embedded cells. The fabricated array of sub‐100‐µm pillars (each loaded with flow‐sorted T‐cell subsets) is arranged in a half‐grid geometry to enable efficient use of the scarce biological sample and ...

Engineering Flexible Nanofibrous Hydroxyapatite Scaffolds With Tunable Degradation and Mechanical Properties for Bone Regeneration

open access: yesSmall, EarlyView.
Conventional hydroxyapatite ceramics are brittle and poorly resorbable, limiting their use in bone repair. To overcome these limitations, flexible scaffolds are fabricated using ceramic nanofibers as structural building blocks. Adjusting nanofiber characteristics allows modulating the mechanical properties and degradation, providing a versatile ...

Impact of Environmental Microparticles on Insect Olfaction

open access: yesEnvironmental Toxicology, EarlyView.
ABSTRACT Terrestrial insects underpin key ecosystem services, including pollination, herbivory regulation, decomposition, nutrient cycling, and disease control. These functions depend on chemical communication that guides insects to food, mates, hosts, shelters, and oviposition sites while helping them avoid threats.

Ventilatory compensation for metabolic acidosis is independent of hypertension in dogs with chronic kidney disease

open access: yesVeterinary Record, EarlyView.
Abstract Introduction Metabolic acidosis is common in dogs with chronic kidney disease (CKD) and induces ventilatory compensation. Systemic arterial hypertension frequently accompanies CKD, but its influence on the ventilatory response remains unclear.

Progress in bone tissue engineering biomaterials: Development, challenges, and prospects

open access: yesVIEW, EarlyView.
Scheme 1 Application of biomaterials in immunomodulation during bone tissue engineering. Abstract Bone defect repair remains a major clinical challenge in orthopedics. Over 2 million cases caused by trauma, tumors, and other factors occur annually, with large‐scale defects posing a particular bottleneck due to limited self‐healing capacity.

Behavioral response of moose Alces alces to summer heat stress

open access: yesWildlife Biology, EarlyView.
Minnesota moose are heat‐stressed during summers, which is adversely impacting their survival. We used both movement and activity data to explore the behavioral responses of Minnesota moose experiencing heat stress, termed ‘hot moose events' or HMEs, to understand how both ambient temperature and available habitat contribute to the ability of these ...

Adenosine—A Regulator of Human Testicular Peritubular Cells

open access: yesAndrology, EarlyView.
ABSTRACT Background Extracellular purines, in particular ATP and adenosine, are regulators of physiological and pathophysiological processes throughout the human body. Roles in the human testis are emerging and include actions on peritubular cells, which form the wall of seminiferous tubules.
