    Rapid Isolation and Purification of Secreted Bacteriocins from Streptococcus mutans and Other Lactic Acid Bacteria
    Authors:  Marcus Cheng, Siew-Ging Gong and Céline M. Lévesque, date: 11/20/2020, view: 2095, Q&A: 0
    [Abstract] Bacteriocins are small ribosomally synthesized antimicrobial peptides produced by some microorganisms including lactic acid bacteria (LAB), a group of Gram-positive bacteria (cocci, rods) expressing high tolerance for low pH. Bacteriocins kill bacteria rapidly and are biologically active at very low concentrations. Bacteriocins produced by LAB ...
    Peptide Feeding and Mechanical Wounding for Tomato Seedlings
    Authors:  Lei Wang, Yan Wang and Georg Felix, date: 03/20/2019, view: 3812, Q&A: 0
    [Abstract] Plants need to respond appropriately to wounding and herbivorous insects. Peptide signals have been implicated in local and systemic induction of appropriate plant defense responses. To study these peptide signals and their perception in host plants, it is important to have reproducible bioassays. Several assays, such as treatment of peptide ...
    An ex vivo Perifusion Method for Quantitative Determination of Neuropeptide Release from Mouse Hypothalamic Explants
    Authors:  Ophélia Le Thuc, Jacques Noël and Carole Rovère, date: 08/20/2017, view: 5988, Q&A: 0
    [Abstract] The hypothalamus is a primary brain area which, in mammals, regulates several physiological functions that are all related to maintaining general homeostasis, by linking the central nervous system (CNS) and the periphery. The hypothalamus itself can be considered an endocrine brain region of some sort as it hosts in its different nuclei several ...
