Lung cancer is currently the leading cause of cancer-related death in worldwide, non-small cell lung cancer (NSCLC) accounts for about 85% of all lung cancers. Surgery, platinum-based chemotherapy, molecular targeted agents and radiotherapy are the main treatment of NSCLC. With the strategies of treatment constantly improving, the prognosis of NSCLC… (More)
The mechanism and conformational changes of farrerol binding to bovine serum albumin (BSA) were studied by spectroscopic methods including fluorescence quenching technique, UV-vis absorption, circular dichroism (CD) spectroscopy and Fourier transform infrared (FT-IR) spectroscopy under simulative physiological conditions. The results of fluorescence… (More)
Mild chemical processes of various analytes and detection methods involving revolutionary strategies in the fields of analytical chemistry, biology and environmental sciences have been extensively developed. This critical review focuses on representative examples of mild chemical processes that can be used in fluorescent chemodosimeters for ion sensing… (More)
The interaction between farrerol and calf thymus DNA in a pH 7.4 Tris-HCl buffer was investigated with the use of neutral red (NR) dye as a spectral probe by UV-vis absorption, fluorescence, and circular dichroism (CD) spectroscopy, as well as viscosity measurements and DNA melting techniques. It was found that farrerol molecules could intercalate into the… (More)
Berberine, a natural product, has been widely used to treat hyperlipoidemia and intestinal diseases. In the present paper, berberine showed a significant anti-proliferative effect to human cervical carcinoma HeLa cells confirmed by 3-(4,5)-dimethyl-thiahiazo(-z-y1)-3,5-di-phenytetrazoliumromide (MTT), flow cytometry analysis (FCM) and so on. The methods… (More)
Hydrazine is an important industrial chemical but also very toxic thus requiring rapid detection agents. A ratiometric fluorescence probe that enables rapid, low-limit and naked-eye detection is successfully designed and used for hydrazine determination in live cells.
This tutorial review presents some recent developments in the construction and applications of cassettes based on resonance energy transfer between fluorescent dyes in the visible and infrared region. We focused on the contributions of different connections between the energy donor and acceptor according to the "through-space" and "through-bond" methods,… (More)
, a Nile Blue based NIR fluorescent dye was reported. is highly effective in specifically labeling lysosomes with low concentration and good photostability in various kinds of live cells. It was first successfully used to observe the disappearance and reproduction of lysosomes during cell division.
A rapid and sensitive analytical method based on reverse-phase high-performance liquid chromatography was first developed to simultaneously determine elsinochrome C (EC) and hypocrellin A (HA) in the submerged fermentation. The mobile phase consisted of acetonitrile-water 60:40 (v/v) with a flow-rate of 1 mL/min. The calibration curves were as follows: y =… (More)
BACKGROUND/AIMS Normomagnesemia is considered atypical in Gitelman syndrome (GS). Here, we describe clinical, pathological and genetic characteristics in Chinese GS patients with or without hypomagnesemia in order to determine whether serum magnesium concentration indicates the severity of the disease. METHODS 7 normomagnesemic and 25 hypomagnesemic GS… (More)
