are compounds whose structures are based on oligomeric flavonoid precursors and vary in the type of linkages between flavonoid units; hydroxylation patterns; stereochemistry of carbons 2, 3 and 4 of the pyran ring and the presence of additional substituents. Some drugs (e....

Mood and anxiety disorders are frequent in the elderly and increase the risk of frailty. This study aimed to identify novel biomarkers of major depressive
Polyphenols are a chemically diverse and abundant10 group of plant-derived compounds, spanning more than 10,000 chemical formulae and several structural families (Supplementary Fig. 1), including polymers (for example, tannins), monomers (for example, flavonoids) and simple phenols (for example, ...
was also used to quantify HOM with the consideration of weight-dependent ion transmission45and sampling loss in the inlet. We processed the raw data using the MATLAB tofTools package (version 603)44. High-resolution analysis was used to identify the peaks with different elemental formulae....
we analysed the molecular composition of sediment pore water dissolved organic matter (DOM) underneath and adjacent to a MediterraneanP. oceanicameadow using ultrahigh-resolution MS24. We found that, across sampling locations, 10–16% of all detected molecular formulae consisted of polyphenols and oth...
This latter class had four known members: ICl, CNCl, BF , and SiF4What is interesting is that at least two of these, BF3 and SiF4, are considered today to be good examples ofLewisacids. 后一类有四个已知成员:ICl、CNCl、BF 和 SiF4 有趣的是,其中至少有两个 BF3 和 SiF4 如今被认为是路...
while guo et al. identify coordinated changes using their formula, integration of our formula into their framework would identify subnetworks with changes that are consistent with an input network of interactions, stimulations and inhibitions. in any case, we wish to stress that for the ...
Seagrasses are among the most efficient sinks of carbon dioxide on Earth. While carbon sequestration in terrestrial plants is linked to the microorganisms living in their soils, the interactions of seagrasses with their rhizospheres are poorly understood
The integration of network pharmacology and TCM are shifting the conventional “one target, one drug” paradigm to “multi-target, multi-component drug” strategy [35]. In recent years, our research groups have identified the candidate drug target of various TCM herbal formulae acting on the ...
