Numerous methods to analyze biogenic amines in biological materials have been described. A versatile and rapid methodology to analyze these compounds in feedstuffs, complete feeds, and animal tissues, however, has not been reported. The current method was developed to address this need. Biogenic amines in feedstuffs, complete animal feeds, and animal tissues were extracted with 10% trichloroace...

Green synthesis of metal nanoparticles through biological resources has attracted attention in recent years. The main reason for that, a lot toxic chemicals as reducing and stabilizing agents are used physical chemical methods which known conventional methods. Organisms such plants, fungi, bacteria, algae alternative sources green nanoparticle because their more eco-friendly nature not be threa...

The local production of proinflammatory cytokines mediates the host response to inflammation, infection, and injury, whereas an overexpression of these mediators can injure or kill the host. Recently, we identified a class of multivalent guanylhydrazone compounds that are effective inhibitors of proinflammatory cytokine synthesis in monocytes/macrophages. The structure of one such cationic mole...

Growing need of potent antibacterial agents has renewed a keen interest in the development of nanomaterials with antibacterial properties. The current work demonstrated the biosynthesis of zinc oxide nanoparticles (ZnO NPs) using aqueous leaf extract of Cardiospermum halicacabum and its bactericidal activity. The resultant biogenic metal oxide nanoparticles were analyzed by various characteriza...

The biogenic synthesis of metal nanomaterial offers an environmentally benign alternative to the traditional chemical synthesis routes. In the present study, the green synthesis of silver nanoparticles (AgNPs) from aqueous solution of silver nitrate (AgNO3) by using Nigella arvensis L. seed powder extract (NSPE) has been reported. AgNPs were characterized by UV-vis absorption spectroscopy with ...

This study reports a scalable green electrochemical synthesis of novel biogenic silver nanoparticles colloid (biogenic AgNPs) in large scale up to 5 liters using the bulk bar and tea leaves (Camellia sinensis) extract (GTE) as reducing agent during process. Under direct-current voltage source, biomolecules GTE can release electrons promote process Ag+ Ag0. More interestingly, formation intermed...

Some lactic acid bacteria (LAB) isolated from fermented foods have been proven to degrade biogenic amines through the production of amine oxidase enzymes. Since little is known about this in relation to wine micro-organisms, this work examined the ability of LAB strains (n=85) isolated from wines and other related enological sources, as well as commercial malolactic starter cultures (n=3) and t...

A sediment core, collected from the western part of the continental slope of the Ross Sea at 2380 m water depth, records Ž . 230 events of the last two climatic cycles 250 kyr . A Th -based chronology was obtained and boundaries of the isotope ex stages were set assuming that biological productivity was enhanced during periods of less ice cover. Then, Th0 , organic ex carbon, biogenic silica an...

Recent trends in food quality and safety promote an increasing search for trace compounds that can affect human health. Biogenic amines belong to this group of substances. They can cause distinctive pharmacological, physiological and toxic effects in organisms. Their amounts are usually increasing as a consequence of the use of poor quality raw materials, during controlled or spontaneous microb...
