An iron-based metal-organic framework as a novel dispersive solid-phase extraction sorbent for the efficient adsorption of tetrabromobisphenol A from environmental water samples.

For environmental safety, it is important to establish a simple, rapid, and sensitive method for emerging pollutants. Here, a dispersive solid-phase extraction (d-SPE) method based on an iron-based metal-organic framework (Fe-MIL-88-NH) combined with high-performance liquid chromatography (HPLC) was developed for tetrabromobisphenol A (TBBPA) in water samples. Fe-MIL-88-NH was synthesized using a solvothermal method and completely characterized.

Complete Genome Sequence of Streptomyces olivoreticuli ATCC 31159 Which can Produce Anticancer Bestatin and Show Diverse Secondary Metabolic Potentials.

Because of its competitive inhibitor activity against aminopeptidase B, bestatin isolated from the broth of Streptomyces olivoreticuli ATCC 31159 is famous and currently used as an approved therapeutic agent for cancer and bacterial infections. It can be used alone or in combination with other antibiotics or anticancer drugs as adjuvant therapy drug for chemotherapy and radiotherapy. Due to the therapeutic importance of bestatin, mining of its biosynthetic mechanism is imperative.

Single-Drop Raman Imaging Exposes the Trace Contaminants in Milk.

Better milk safety control can offer important means to promote public health. However, few technologies can detect different types of contaminants in milk simultaneously. In this regard, the present work proposes a single-drop Raman imaging (SDRI) strategy for semiquantitation of multiple hazardous factors in milk solutions.

Single nucleotide polymorphisms of ABCB1 gene and response to etanercept treatment in patients with ankylosing spondylitis in a Chinese Han population.

Background: Etanercept was highly recommended for patients with ankylosing spondylitis (AS), as its efficacy has been confirmed in AS, while genetic polymorphisms, by affecting drug metabolism or drug receptor, lead to interindividual variability in drug disposition and efficacy. Therefore, this study aims to investigate whether ABCB1 gene polymorphisms can predict therapeutic response to etanercept in patients with AS.

Methods: A total of 185 patients with AS in our hospital were recruited into our study from December 2012 to May 2015.

[Preliminary study on identification of oil products using laser-Raman fingerprint spectrum].

Laser-Raman spectroscopy technology was used for measuring and analyzing properties of oil products. Through comparing with the Raman shifts and relative Raman intensity ratios of the main fingerprint peaks, different kinds of oil products were identified successfully. Furthermore, the Raman spectra of the same type of petroleum products obtained from different private gas stations were measured and the petroleum qualities were detected.
