A mechanism of co-reactive group poisoning (CGP) was discovered for designing efficient I2 vapor sensors for early warning of a nuclear emergency, which give an ultra-low detection limit of 0.13 ppt as well as high selectivity.

This paper aims to synthesise, characterise and find out the properties of a model dye for convenient union dyeing of wool, polyester and wool/polyester blend fabric compared with C.I. Disperse Yellow 23. The reactive disperse dye was prepared containing sulphatoethylsulphone (SES) as a reactive group. The dye was synthesised by diazotization and coupling reaction. Firstly, we synthesized azo dye intermediate I using 1-aminobenzene-4-sulphatoethylsulphone diazotized and then coupled it with aniline. The synthesized azo dye intermediate I was diazotized and coupled with phenol to give dye 2. Different factors affecting the dyeability and fastness properties of SES dye 2 were thoroughly investigated on wool, polyester and wool/polyester blend fabrics in comparison with C.I. Disperse Yellow 23 dye 1. Maximum exhaustion and total fixation yield using sulphatoethylsulphone (SES) dye 2 were achieved on wool fabric at neutral pH 7. The dye showed high dyeing performance due to its nonionic reactive VS derivative. The dyeing results indicate high quality dyeing properties

Reactive Group

Syntheses of azo dyes which incorporate a bisulphite-isocyanate adduct as a ?masked? reactive group are described. Two general methods are used. One is based on couplings with diazotized sodium 4- aminobenzylaminooxomethanesulphonate (2). The other is achieved by coupling aromatic dia- zonium salts with sodium 6-(3?- dimethylaminophenylureido)hexylaminooxomethanesulphonate (4). The synthesis of (4) involves monofunctional addition of an arylamine to hexamethylene diisocyanate.

Purpose Panitumumab, a fully human monoclonal antibody targeting the epidermal growth factor receptor (EGFR), is approved in the United States and Europe for the treatment of refractory metastatic colorectal cancer (mCRC). Skin toxicities are the most common adverse events with EGFR inhibitors. This is the first study designed to examine differences between pre-emptive and reactive skin treatment for specific skin toxicities in patients with mCRC for any EGFR inhibitor. Patients and Methods Patients receiving panitumumab-containing therapy were randomly assigned 1:1 to pre-emptive or reactive treatment (after skin toxicity developed). Pre-emptive treatment included use of skin moisturizers, sunscreen, topical steroid, and doxycycline. The primary end point of the study was the incidence of protocol-specified ≥ grade 2 skin toxicities during the 6-week skin treatment period. Quality of life (QOL) was assessed with the Dermatology Life Quality Index (DLQI). Results Of 95 enrolled patients, 48 received pre-emptive treatment, and 47 received reactive treatment. The incidence of protocol-specified ≥ grade 2 skin toxicities during the 6-week skin treatment period was 29% and 62% for the pre-emptive and reactive groups, respectively. Mean DLQI score change from baseline to week 3 was 1.3 points and 4.2 points in the pre-emptive and reactive groups, respectively. Conclusion The pre-emptive skin treatment regimen was well tolerated. The incidence of specific ≥ grade 2 skin toxicities during the 6-week skin treatment period was reduced by more than 50% in the pre-emptive group compared with the reactive group. Patients in the pre-emptive group reported less QOL impairment than patients in the reactive group.
