Application
Latex beads, carboxylate-modified polystyrene, fluorescent red has been used:
- along with Milli-Q for fluid dynamic studies
- along with bile salts for confocal studies
- for particle encapsulation
Carboxylate-modified polystyrene latex beads have been used to collect morphofunctional data about the immune systems of Carabus lefebvrei, a helicophagous Italian endemic ground beetle often used as an indicator of the habitat quality of the Apennines mountain forests. Carboxylate-modified polystyrene latex beads have also been used to inform comparative studies on immunity defense mechanisms of adults and larvae of the coleopteran Cetonischema aeruginosa and to investigate the phagocytic activity of cultured rat thyroid cells.

Surface chemical and biochemical functionalization is a fundamental process that is widely applied in many fields to add new functions, features, or capabilities to a material's surface. Here, we demonstrate that surface acoustic waves (SAWs) can enhance the chemical functionalization

Patients with acute-on-chronic liver failure (ACLF) usually exhibit defective monocyte function and excessive systemic inflammatory response. Interleukin-33 (IL-33) acts as a danger-associated molecular pattern (DAMP) to modulate immune response. However, the role of IL-33 in regulating monocyte function during hepatitis

The Porcine Myeloid Antibacterial Peptide (PMAP)-23 is a porcine host defence peptide with strong antibacterial activity against Gram-positive and Gram-negative bacteria, and fungi. PMAP-23 and truncated/mutated derivatives were tested for antibacterial and immunomodulatory activities to determine core elements of the
