A magnetic molecularly imprinted electrochemical sensor was developed for selective determination of sufentanil (SUF) based on carbon paste electrode (CPE) modified with methacrylic acid-ethylene glycol dimethacrylate-coated Fe3O4 nanoparticles (Fe3O4@MAA-EGDMA NPs). The structural properties, chemical structure, and electrochemical behaviors of the imprinted sensor were characterized by X-ray diffraction analysis (XRD), Fourier transform infrared spectroscopy (FT-IR), and square wave voltammetry (SWV), respectively.

The efficient synthesis of 12-substituted-3,4,4a,5,12,12a-hexahydrobenzo[b]acridine-1,6,11(2H)-triones starting from 2-amino-1,4-naphthoquinone, 1,3-cyclohexanedione, and different (hetero)aromatic aldehydes was developed. These reactions were carried out in acetic acid under microwave irradiation in the presence of p-toluenesulfonic acid as catalyst. The structure of the newly synthesized compounds were confirmed employing spectroscopic data as well as elemental analysis. The plausible mechanism of these three-component domino reactions was also described.

The winged-helix domain within the N-terminus of human MUS81 has been considered as potential target for drug development since the inhibition of this protein might significantly enhance the sensitivity of various cancer cells towards anticancer drugs. Nine cytotoxic triterpenoids previously purified from Helicteres hirsuta and Pterospermum truncatolobatum were selected for the docking experiment.

This paper focuses on optimizing the chromatographic instrumental operating parameters and the solid phase extraction conditions using HLB cartridges. Results from the method validation showed that the method has sub ng/L LOQs (0.10-0.60 ng/L), quantitative recoveries at the concentrations near the LOQs (74.4-122.8%) and high repeatability with acceptable %RSD (15.6-38.3%).

Multiple studies suggest a key role for gut microbiota in IgE-mediated food allergy (FA) development, but to date, none has studied it in the persistent state. The gut microbiota composition of allergic patients was significantly different compared to age-matched controls both in α-diversity and β-diversity.

The Wiskott–Aldrich syndrome protein (WASp) family of actin-nucleating factors are present in the cytoplasm and in the nucleus. The role of nuclear WASp for T cell development remains incompletely defined. Methods: We performed WASp chromatin immunoprecipitation and deep sequencing (ChIP-seq) in thymocytes and spleen CD4+ T cells.

Ebook "Chemistry and technology of yoghurt fermentation" reviews the chemistry behind the production of yoghurt through acidification of milk. It quantifies the changes in physical and chemical properties of yoghurt during fermentation with microbial organisms (such as Lactobacillus bulgaricus and Streptococcus thermophilus). It has been found that this symbiosis has an optimal development at a temperature of ca. 45°C with the transformation of lactose into lactic acid and small amounts of acetaldehyde, diacetyl and volatile acids.
