SIRT1 inhibitors within Qing-Luo-Yin alleviated white adipose tissues-mediated inflammation in antigen-induced arthritis mice.

Background: White adipose tissues (WAT) release large amounts of inflammatory mediators, which are responsible for the pathology of rheumatoid arthritis (RA).

Purpose: The current study investigated the involvement of WAT in the treatments of antigen-induced arthritis (AIA) mice with the herbal formula Qing-Luo-Yin (QLY).

Methods: Cytokines and biochemical/metabolic indicators were determined by ELISA and colorimetry methods, respectively.

Evaporative Deposition of Surfactant-Laden Nanofluid Droplets over a Silicon Surface.

Morphologies of evaporative deposition, which has been widely applied in potential fields, were induced by the competition between internal flows inside evaporating droplets. Controlling the pattern of deposition and suppressing the coffee-ring effect are essential issues of intense interest in the aspects of industrial technologies and scientific applications. Here, evaporative deposition of surfactant-laden nanofluid droplets over silicon was experimentally investigated.

Gene Expression Analysis Reveals Key Genes and Signalings Associated with the Prognosis of Prostate Cancer.

It is urgent to identify novel biomarkers for prostate cancer (PCa) prognosis and to understand the mechanisms regulating the tumorigenesis for PCa treatment. In this study, GSE17951 and TCGA were used to identify the differentially expressed genes (DEGs). Our study demonstrated that 1533 genes with increased expression and 2301 genes with decreased expression in PCa.

PEG modification enhances the in vivo stability of bioactive proteins immobilized on magnetic nanoparticles.

Objective: To increase the in vivo stability of bioactive proteins via optimized loading methods.

Results: β-Glucosidase (β-Glu), as a model protein, was immobilized on magnetic nanoparticles(denoted as MNP-β-Glu) by chemical coupling methods and was further modified by poly(ethylene glycol) (PEG) molecules (denoted as MNP-β-Glu-PEG) to increase its stability. The physicochemical properties of the as-prepared nanohybrids, including the particle size, zeta potential, and enzyme activity, were well characterized.

[Source Profiles of Volatile Organic Compounds (VOCs) from Typical Solvent-based Industries in Beijing].

Based on the demand for a volatile organic compounds (VOCs) emissions inventory for Beijing and for the reduction in VOC emissions, the three major solvent-based industries of automobile manufacturing, furniture manufacturing, and publication printing were selected for this study. In each case, emissions link negative pressure sampling was used in combination with laboratory-based GC-MS/FID to obtain the VOC spectra. The results show that there are significant differences in the emission of VOCs from the main stages of automobile manufacturing.

Enzalutamide alleviates anxiety and depression as well as improves quality of life compared to bicalutamide in metastatic castration-resistant prostate cancer patients: a cohort study.

Background: This study aimed to evaluate the efficacy of enzalutamide compared with bicalutamide on anxiety, depression and quality of life (QoL) in metastatic castration-resistant prostate cancer (mCRPC) patients.

Methods: Totally 134 mCRPC patients were consecutively enrolled and baseline data were documented, among whom 53 patients received enzalutamide as Enzalutamide group, while 81 patients received bicalutamide as Bicalutamide group. Anxiety and depression were assessed by Hospital Anxiety and Depression Scale (HADS) as well as Zung Self-Rating Anxiety/Depression Scale (SAS/SDS), and QoL was assessed by Functional Assessment of Cancer Therapy (FACT)-General/Prostate (FACT-G/FACT-P) questionnaires at W0 (baseline), W12, W24, W36, W48 and W60.

Catalytic Asymmetric Construction of the Tryptanthrin Skeleton via an Enantioselective Decarboxylative [4 + 2] Cyclization.

The first catalytic asymmetric construction of the tryptanthrin skeleton has been established, taking advantage of a palladium(0)/chiral ligand-catalyzed enantioselective decarboxylative [4 + 2] cyclization of vinyl benzoxazinanones with isatins. This reaction has not only provided a direct and efficient method for constructing chiral tryptanthrin skeleta in high yields and excellent enantioselectivities (up to 97% yield, >99% ee) but also represents the first catalytic asymmetric decarboxylative cyclization of vinyl benzoxazinanones with isatins.

Substrate-Controlled Regioselective Arylations of 2-Indolylmethanols with Indoles: Synthesis of Bis(indolyl)methane and 3,3'-Bisindole Derivatives.

This approach will not only provide an important strategy for the diversified synthesis of bis(indolyl)methane and 3,3'-bisindole derivatives but also serve as a good example for substrate-controlled regioselective reactions.
