The aim of this work was to study the cooperage potential oak species Quercus pyrenaica, which is widespread throughout Iberian Peninsula. A red wine 2016 vintage aged in new barrels made from petraea and alba for 12 months. This process repeated with a similar subsequent using same order compare performances Q. pyrenaica that had been used one year equivalent barrels. results indicate releases...

The biological function of chaperone complexes is to assist the folding of non-native proteins. The widely studied GroEL chaperonin is a double-barreled complex that can trap non-native proteins in one of its two barrels. The ATP-driven binding of a GroES cap then results in a major structural change of the chamber where the substrate is trapped and initiates a refolding attempt. The two barrel...

In the rodent primary somatosensory cortex, the thalamocortical axons (TCAs) are organized into clusters that correspond to functional units in the periphery. Around these axons, neurons in layer IV aggregate as barrels. To understand how this organization emerges, we analyzed TCA development in mice that do not form barrels, the monoamine oxidase A knock-out (MAOA-KO), and in MAOA/5-HT(1B) rec...

We studied thalamocortical afferent (TCA) growth into somatosensory cortex as the whisker barrels emerge in postnatal mice. Ingrowing fibers from the ventrobasal (VB) thalamus were selectively labeled by two means. Under direct vision, individual axons and populations of axons were labeled in vitro with HRP, or in fixed tissue with Dil (1,1'-dioctodecyl-3,3,3',3'-tetramethylindocarbocyanine per...

Abstract The production of high quality spirits implies an aging period in wooden barrels, resulting numerous physicochemical reactions between the wood and beverage. Oak is main used process alcoholic beverages worldwide. However, Brazil, use tropical species can be a viable option, allowing for innovation characteristics spirits. This study aimed to determine aromatic profiling flavor active ...

Cobalamin-independent methionine synthase (MetE) catalyzes the transfer of a methyl group from methyltetrahydrofolate to L-homocysteine (Hcy) without using an intermediate methyl carrier. Although MetE displays no detectable sequence homology with cobalamin-dependent methionine synthase (MetH), both enzymes require zinc for activation and binding of Hcy. Crystallographic analyses of MetE from T...
