[20], hydroxytyrosol has a higher antioxidant activity than oleuropein and verbascoside. However, the results obtained in this work suggest that in olive leaf aqueous extracts, both the hydroxytyrosol and the hydroxytyrosol hexoside are more labile compounds and are therefore less stable than ...

questions in sections that are unrelated to other sections. The advantage of an omnibus survey is that a range of businesses may pool together to cover the cost of the administration and implementation of the survey; albeit that the survey will contain sections with questions germane to specific ...
Forty preservice chemistry teachers were guided to analyze 10 middle school science and 10 high school chemistry textbooks. Overall, the textbooks included unfair gender representations, a considerably higher number of input and processing than output level questions, and high load of science terminology...
Quantitative research is widely used in the realms of social sciences, such as biology, chemistry, psychology, economics, sociology, and marketing. Research teams collect data that is significant to proving or disproving a hypothesis research question – known as the research objective. When they col...
(Fig.4c; Supplementary Fig.6b). In many cases, we want to know if the absolute load of a taxon is higher or lower under different conditions (e.g., in mice on ketogenic and control diets). When the total microbial load varies among samples, analyses of relative abundance cannot ...
From a crystal chemistry perspective, the Ca3SiO5 particle surface is unlikely to be inert when exposed to atmospheric water Ca2 þ vapour. cations Specifically, with oxide Ca3SiO5 is an ionic crystal of and monomeric silicate anions (3Ca2 þ Á O2 À Á SiO4 4 À ) (refs ...
as it is abundant in every biological sample and is often uniformly distributed across the sample. However, it has been shown that carbon is not an optimal internal standard [99], as its ionization potential is significantly higher than those of commonly investigated elements, such as most transi...
1. The chemical profiling of Chinese medicinal materials was searched from the Chinese Academic Journal Network Publishing Database (CAJD) (https://www.cnki.net/) by using the combinations of the keywords (“name”, “progress”, and “chemistry”) in the title. Original research on ingredient...
Another group of labeling reagents targets the peptide N-terminus and the epsilon-amino group of lysine residues. Most of the time, this is realized via the very specificN-hydroxysuccinimide (NHS) chemistry or other active esters and acid anhydrides as in, e.g., the isotope-coded protein labe...
