This invention relates to an improved process for the production of high molecular weight polyurethanes which are free from isocyanate groups and are soluble in organic solvent in reduced reaction times. The reactants, polyol and isocyanate, for example, are mixed together with solvent and the ...
The Random woodland design was less accurate compared to the various other two designs. These results display the potency of tree-based models for forecasting the solubility and thickness of chemical substances while having potential applications in dedication of drug solubility just before process design...
Many antimicrobials, such as the polyenes, macrolides, echinocandins, penicillins and essential oils (EOs), are natural products or derivatives thereof9,10,11,12,13. EOs are complex mixtures of secondary plant metabolites that have a relatively high vapour pressure, are poorly water-soluble and k...
The mature grape berry, via pressed must, provides a source of nitrogenous substances in the form of free amino acids and cleaved peptides, proteins and nucleic acid derivatives, and in mineral ammonium salts that collectively make up the fermentable nitrogen metabolized by yeast during alcoholic fe...
1、长句多 Many man-made substances are replacing certain natural materials because either the quantity of the natural product cannot meet our ever-increasing requirement, or, more often, because the physical properties of the synthetic substance, which is the common name for man-made materials...

In the AD transgenic Tg2576 mouse brain, curcumin significantly lowered the levels of oxidized proteins and IL-1β, and decreased the levels of insoluble and soluble Ab and plaque burden without affecting amyloid precursor protein. Curcumin has been evaluated in a clinical trial for the prevention...
poorly understood compared to that for molecular substances, leading to enormous challenges in determining meaningful dose-response curves [109,110]. Additionally, the dynamic nature of NPs and their tendency to evolve and transform during storage [111] or upon interaction with media [112] makes ...
