8 ore fa · Therefore, the lichen polymeric biomass is commonly from a fungal origin, in which α-glucans, β-glucans, and galactomannans can be isolated in large yields. Furthermore, due to their chemotaxonomic importance, lichen polysaccharides based on glucan and galactomannan types have been pointed out.
8 ore fa · Chamazulene (CA) is an intensely blue molecule with a wealth of biological properties. In cosmetics, chamazulene is exploited as a natural coloring and soothing agent. CA is unstable and tends to spontaneously degrade, accelerated by light. We studied the photodegradation of CA upon controlled exposure to UVB-UVA irradiation by multiple techniques, including GC-MS, UHPLC-PDA-ESI-MS/MS and by ...
8 ore fa · Enhanced tetracycline degradation through nonradical processes by modulating the exposure of active sites on the iron nanoconfined catalysts Enhanced the dehydrocyclization of 1,4-butanediol to γ-butyrolactone via the regulation of interface oxygen vacancies in Cu-MgO-CeO2 catalyst
8 ore fa · A healthy full-term baby will flex the neck to lift the head from the surface along with the body; a hypotonic infant’s head will fall back (Figure 17.1A). Another way to assess tone is to suspend the baby with the abdomen lying on your outstretched hand—infants with normal tone will straighten their back, flex their limbs, and hold their head straight or extended.
