The expression of the potent vasoactive peptide neuropeptide Y (NPY) was studied in 16 clinically and/or histologically diagnosed human pheochromocytomas and 3 human neuroblastoma tumors. All tumors contained NPY in concentrations ranging from 21 pmol/g of tissue, similar to that found in normal adrenal tissue, to 91,000 pmol/g (median, 1,700 pmol/g). Three control tumors of Cushing's type did ...

This study describes an attempt to replicate experiments from the paper "Effect of BMAP-28 Antimicrobial Peptides on Leishmania major Promastigote and Amastigote Growth: Role of Leishmanolysin in Parasite Survival," which was submitted to the Reproducibility Initiative for independent validation. The cathelicidin bovine myeloid antimicrobial peptide 28 (BMAP-28) and its isomers were previously ...

Fish losses from infectious diseases are a significant problem in aquaculture worldwide. Therefore, we investigated the ability of cationic antimicrobial peptides to protect against infection caused by the fish pathogen Vibrio anguillarum. To identify effective peptides for fish, the MICs of certain antimicrobial peptides against fish pathogens were determined in vitro. Two of the most effectiv...

Three antibacterial proteins were purified from the culture medium of NIH-Sape-4, an embryonic cell line of Sarcophaga peregrina (flesh fly). Sequencing studies showed that two of these proteins belong to the sarcotoxin I family, potent antibacterial proteins purified from the hemolymph of Sarcophaga larvae, whereas the other protein, named sapecin, is a new protein consisting of 40 amino acid ...
