CCR4 is a chemokine receptor highly expressed by Th2 cells, and regarded as a potential therapeutic target for atopic dermatitis (AD). CCL17 and CCL22 are the CCR4 ligands, and thymic stromal lymphopoietin (TSLP) is shown to promote the expression of

A new indirect chemosensor for the detection of cyanide in blood is developed. 2-(5-Bromo-2-pyridylazo)-5-[N-n-propyl-N-(3-sulfopropyl)amino]phenol, a yellow dye, forms a blue-coloured complex with palladium ions. The yellow colour of this complex is

Cyanide is highly toxic to humans and the environment. It is very important to develop an on-site system for the quantitative analysis of cyanide with high sensitivity and reliability. In this study, we developed a cyanide detection system based on t
