Antimicrobial peptides (AMPs) are small, potent molecules that serve as a crucial first line of defense across a wide range of organisms, including fish. In this study, we investigated the antimicrobial properties of a novel peptide, spanning residues 52 to 80 of the full-length histone H2A protein, comprising a total of 29 amino acids. This peptide, designated as Histone H2A-29 (TroH2A-29), was derived from the golden pompano (Trachinotus ovatus) and evaluated for its activity against both Gram-positive bacteria, Lactococcus garvieae and Staphylococcus epidermidis, and Gram-negative bacteria, Vibrio alginolyticus and Vibrio harveyi.

This study investigates an L-type lectin, NdLTL1, derived from Neocaridina denticulata sinensis, emphasizing its role in immune defense through carbohydrate binding and bacterial agglutination. Bioinformatics analysis identified 179 lectin sequences, leading to subsequent investigations into the structure and function of NdLTL1. The open reading frame (ORF) of NdLTL1 spans 966 bp and encodes a protein consisting of 321 amino acids (36.

Cold agglutinin syndrome is a form of acquired hemolytic anemia that typically arises from underlying conditions, such as infections, autoimmune disorders or lymphoid malignancies. The majority of patients remain asymptomatic and are diagnosed with anemia through routine complete blood count (CBC) testing. The present study describes the case of a male patient in his 50s who sought a second opinion at the authors' clinic due to newly detected anemia.

Background: Ethylenediamine tetraacetate/glycine acid (EGA) and chloroquine diphosphate (CDP) are used in transfusion testing to dissociate IgG antibodies from red blood cells (RBCs). However, the ability of these reagents to dissociate IgM antibodies sensitized to RBCs has not been comprehensively elucidated. We investigated whether EGA and CDP could dissociate cold-reactive antibodies from RBCs and their effect on RBCs after dissociation treatment.
