Substitution of petrochemical compounds for polyphenols of natural origin reinforced with cellulose nanofibrils to formulate adhesives for wood bonding
Environ Sci Pollut Res Int. 2023 May 20. doi: 10.1007/s11356-023-27655-1. Online ahead of print.ABSTRACTVegetable tannins are excellent options to produce adhesives for the panel industry since they have the capacity to reduce formaldehyde emissions and are derived from renewable sources. They also allow for the possibility of increasing the resistance of the glue line through the use of natural reinforcements such as cellulose nanofibrils. Condensed tannins, polyphenols isolated from tree bark, are widely studied for the production of natural adhesives as an alternative to commercial synthetic adhesives. So, the purpose o...

World ’s largest ‘scent arena’ reveals bloody preferences of mosquitoes
In the dead of night, 200 bloodthirsty creatures make their way through a tented mesh arena the size of an ice rink. Scientists study them from afar, pumping in air scented with the aroma of human prey. They’re hoping to reveal just what triggers these deadly predators.
This isn’t the setup for an upcoming zombie movie. “It’s the world’s largest multichoice smell test for mosquitoes”—a giant experiment to figure out why the deadly insects prefer some people over others, explains study leader Conor McMeniman, a molecular biologist at Johns Hopkins University. The results, he says, could help scientists d...

Proteome profiling of vascular sap regarding Eucalyptus grandis, Eucalyptus urophylla, and Eucalyptus camaldulensis
In this study, a quantitative proteome dataset of the vascular sap proteome of three commercially importantEucalyptus species was shown. Protein extraction was carried out using a pressure bomb, whereas only in silico predicted extracellular proteins were considered as part of the sap proteome. A total of 132 different proteins were identified in all threeEucalyptus species and the most abundant proteome subset within all three species was comprised of proteins involved in the carbohydrate metabolic process, proteolysis, components of membrane, and defense response. The sap proteome of the speciesE. grandis andE. urophylla...

Anti-inflammatory mechanisms of eucalyptol rich Eucalyptus globulus essential oil alone and in combination with flurbiprofen
This study was designed to evaluate the anti-inflammatory, analgesic and anti-pyretic properties of Eucalyptus globulus essential oil alone and in combination with flurbiprofen. GC-MS analysis was performed to screen chemical composition of oil. In vitro anti-inflammatory assay (membrane stabilization assay) and in vivo inflammatory acute (carrageenan and histamine-induced paw oedema) and chronic (cotton pellet-induced granuloma and Complete Freund's adjuvant-induced arthritis) models were performed to check anti-inflammatory properties. Acetic acid-induced algesia and yeast-induced pyrexia models were performed to chec...
