β-actin function in platelets and red blood cells can be performed by γ-actin and is therefore independent of actin isoform protein sequence.

Actin is an essential component of the cytoskeleton in every eukaryotic cell. Cytoplasmic β-and γ-actin are over 99% identical to each other at the protein level, but are encoded by different genes and play distinct roles in vivo. Blood cells, especially red blood cells (RBC), contain almost exclusively β-actin, and it has been generally assumed that this bias is dictated by unique suitability of β-actin for RBC cytoskeleton function due to its specific amino acid sequence.

Distinct Hemostasis and Blood Composition in Spiny Mouse .

The spiny mouse ( species) is capable of scarless wound regeneration through largely yet unknown mechanisms. To investigate whether this capacity is related to peculiarities of the hemostatic system, we studied the blood of in comparison to (Balb/c) to reveal differences in blood composition and clotting in both males and females. In response to surgical manipulations, blood clots formed in wounds of comprised a stronger hemostatic seal with reduced surgical bleeding in comparison with Balb/c.

Directed Design, Screening and Antiglycation Activity for 3-Substituted Thiazolium Derivatives, New Analogs of Alagebrium.

Preliminary ab initio calculations led to the synthesis of novel substituted thiazolium salts, analogs of Alagebrium, which were further explored in vitro for their potential as inhibitors of the glycation reaction utilizing three distinct assays: inhibition of fluorescent AGEs formation, anticrosslinking, and deglycation. Despite the unidirectionality of the assays, distinct differences were observed in the mechanisms of interference and activity manifestation by the compounds. The gathered data permitted the formation of hypotheses about the molecular fragments of the studied antiglycators that are of utmost significance in each assay, thereby guiding future design endeavors.
