Effects of household cooking methods on changes of tissue structure, phenolic antioxidant capacity and active component bioaccessibility of quinoa.

The effects of four household cooking methods including germination (Ger), baking, normal pressure steaming (NPS) and high pressure steaming (HPS) treatments, on tissue structure, tocopherol, antioxidant capacity and active component (ferulic acid and tocopherol) bioaccessibility of different colored quinoa were investigated. The results showed that Ger increased the phenolic contents and antioxidant capacity, but decreased the contents of tocopherol. The steaming processes destroyed the tissue structure of quinoa to a large extent, causing a significant loss of phenolic/flavonoid components and the resultant decreased antioxidant capacity.

Methylated Metabolites of Chicoric Acid Ameliorate Hydrogen Peroxide (HO)-Induced Oxidative Stress in HepG2 Cells.

Chicoric acid (CA) can display health benefits as a dietary polyphenol. However, as CA is widely metabolized , the actual compounds responsible for its bioactivities are not entirely known. Herein, the major methylated metabolites of CA were isolated from an co-incubation system, and their structures were elucidated.

Determination and Tissue Distribution Comparisons of Atractylodin after Oral Administration of Crude and Processed Atractylodes Rhizome.

Background: is one of the most often used drugs in traditional Chinese medicine. Stir frying with wheat bran is the most common processing method. To clarify the principle of processing, an experiment was carried out to compare the tissue distribution of typical constituent after oral administration of raw and processed ones.

Carbon-Based CsPbBr Perovskite Solar Cells: All-Ambient Processes and High Thermal Stability.

The device instability has been an important issue for hybrid organic-inorganic halide perovskite solar cells (PSCs). This work intends to address this issue by exploiting inorganic perovskite (CsPbBr) as light absorber, accompanied by replacing organic hole transport materials (HTM) and the metal electrode with a carbon electrode. All the fabrication processes (including those for CsPbBr and the carbon electrode) in the PSCs are conducted in ambient atmosphere.

Colloidal Precursor-Induced Growth of Ultra-Even CHNHPbI for High-Performance Paintable Carbon-Based Perovskite Solar Cells.

Carbon-based hole transport material (HTM)-free perovskite solar cells (PSCs) have attracted intense attention due to their relatively high stability. However, their power conversion efficiency (PCE) is still low, especially for the simplest paintable carbon-based PSCs (C-PSCs), whose performance is greatly limited by poor contact at the perovskite/carbon interface. To enhance interface contact, it is important to fabricate an even-surface perovskite layer in a porous scaffold, which is not usually feasible due to roughness of the crystal precursor.

Determination and Pharmacokinetic Comparisons of Atractylodin after Oral Administration of Crude and Processed Atractylodis rhizoma.

Background: In traditional Chinese medicine, Atractylodis rhizoma is the dried rhizome of Atractylodes lancea (Thunb.) DC. or Atractylodes chinensis (DC.
