Inhibiting NF-κB inducing kinase improved the motor performance of ALS animal model.

Background: Amyotrophic lateral sclerosis (ALS) is a typical neurodegenerative disorder typically characterized by inflammation activation. However, the relationship between non-canonical NF-κB (ncNF-κB) pathway activation and ALS progression is not clear.

Methods: We tested the ncNF-κB pathway in the ALS animal model including hSOD1-G93A transgenic mice and TBK1 deletion mice.

Simultaneous determination of multiple androgens in mice organs with liquid chromatography tandem mass spectrometry.

Prostate cancer (PCa) is the most commonly diagnosed cancer in men worldwide. It is essentially dependent on potent androgens, such as testosterone (T) and dihydrotestosterone (DHT). The precursors of T and DHT, which includes androstenedione (A4) and dihydroepiandrosterone (DHEA), and also the metabolites of DHT, 5α-androstane-3α,17β-diol (3α-Diol) and 5α-androstane-3β,17β-diol (3β-Diol) are able to affect the development of PCa.

Preparation and characterization of 4-isopropylcalix[4]arene-capped (3-(2-O-β-cyclodextrin)-2-hydroxypropoxy)-propylsilyl-appended silica particles as chiral stationary phase for high-performance liquid chromatography.

A new type of 4-isopropylcalix[4]arene-capped (3-(2-O-β-cyclodextrin)-2-hydroxypropoxy)propylsilyl-appended silica particles (IPC4CD-HPS) has been prepared by treatment of bromoacetate-substituted (3-(2-O-β-cyclodextrin)-2-hydroxypropoxy)propylsilyl-appended silica particles (BACD-HPS) with 4-isopropylcalix[4]arene oxyanions in anhydrous N-methyl-2-pyrrolidone. The bonded silica IPC4CD-HPS has been successfully used as chiral stationary phase (CSP) in high-performance liquid chromatography (HPLC) for the first time. The synthetic stationary phase was characterized by means of elemental analysis and Fourier transform infrared spectroscopy.
