Lipid concomitant γ-oryzanol decreased oil absorbency of French fries by changing the microstructure of French fries and physical properties of frying oil.

Background: The aim of this research was to evaluate the possibility of lipid concomitant γ-oryzanol reducing oil absorbency of fried foods and the underlying mechanism. Therefore, the influence of γ-oryzanol on moisture and oil content, and distribution and micromorphology of French fries and the viscosity, fatty acid composition and total polar compounds content of rice bran oil (RBO) after frying were studied.

Results: Our results showed that the incorporation of low concentration of γ-oryzanol [low addition group (LAG)] (5.

Comparison of biochemical properties of membrane-bound and soluble polyphenol oxidase from Granny Smith apple (Malus × domestica Borkh.).

Polyphenol oxidase from Granny Smith apples was purified and characterized in both its soluble form (sPPO) and its membrane-bound form (mPPO). Both forms were purified by temperature-induced phase partitioning, precipitation with ammonium sulfate, and ion exchange chromatography. The specific activity of mPPO was 19.

MicroRNA-1301-Mediated RanGAP1 Downregulation Induces BCR-ABL Nuclear Entrapment to Enhance Imatinib Efficacy in Chronic Myeloid Leukemia Cells.

Chronic myeloid leukemia (CML) is a myeloproliferative disease. Imatinib (IM), the first line treatment for CML, is excessively expensive and induces various side effects in CML patients. Therefore, it is essential to investigate a new strategy for improving CML therapy.

Development of a sensitive long-wavelength fluorogenic probe for nitroreductase: a new fluorimetric indictor for analyte determination by dehydrogenase-coupled biosensors.

Nitroreductase (NTR) is a flavin-containing enzyme that uses NADH as the electron source to reduce nitroaromatic compounds to the corresponding amines. Previous studies have shown that nitroreductase-targeted latent fluorophores exhibit low solubility in the aqueous media and fluoresce at lower wavelengths upon uncloaking, thus limiting their effective applications. Here, we have prepared a new switch-on long-wavelength latent fluorogenic substrate, NTRLF (4), for NTR.

Development of a long-wavelength fluorescent probe based on quinone-methide-type reaction to detect physiologically significant thiols.

We synthesized a new long-wavelength latent fluorimetric probe BCC (6) to detect physiologically significant thiols. The fluorogenic chemical transformation of BCC triggered by thiols is through a tandem reaction, thiol-induced benzoquinone reduction, and quinone-methide-type rearrangement reaction, which are spontaneous and irreversible at physiological temperature in aqueous media. The fluorescence signal revealed by this process is specific and exhibited in the near-red spectrum region with emission maxima at 595 nm, and it could be competitively inhibited by thiols scavenger, N-ethylmaleimide.

Synthesis of a new long-wavelength latent fluorimetric indicator for analytes determination in the DT-Diaphorase coupling dehydrogenase assay system.

We synthesized a new long-wavelength latent fluorogenic probe BQC (1) to monitor DTD activity. The fluorogenic chemical transformation of BQC triggered by DTD in the presence of NADH is through a series of tandem reactions, DTD-catalyzed benzoquinone reduction, trimethyl-locks cyclization and intramolecular urea formation, which are spontaneous and irreversible at physiological temperature in aqueous media. The fluorescence signal revealed by this process is specific and exhibited in the near red spectrum region with emission maxima at 595 nm, and it could be competitively inhibited by menadione.
