CONTEXT: Smoking is the first cause of preventable death in France and in the world. Without help, it was shown that 80 % of smokers who try to quit smoking relapse after one month with a low long-term success rate. Smoking reduction can concern smokers who did not want to quit or failed in their attempt to weaning. The final aim is to increase attractiveness of drug therapies by developing new products, such as electronic cigarettes, that can compete cigarette without reproducing its harmful effects...

Subtle structural features such as disorder and anharmonic motion may be accurately characterized from nuclear density distributions (NDDs). As a viable alternative to neutron diffraction, this paper introduces a new approach named the nuclear-weighted X-ray maximum entropy method (NXMEM) for reconstructing pseudo NDDs. It calculates an electron-weighted nuclear density distribution (eNDD), exploiting that X-ray diffraction delivers data of superior quality, requires smaller sample volumes and has higher availability...

PURPOSE: Evaluation of tumor targeting pegylated EphA2 peptide coated nanoparticles (ENDDs) of a novel anticancer agent DIM-C-pPhC6H5 (DIM-P) and Docetaxel (DOC) and investigate its antitumor activity and potential for treatment of lung cancer. METHODS: Nanoparticles were prepared with DIM-P and DOC (NDDs) using Nano-DeBEE. ENDDs were prepared by conjugating NDDs with 6His-PEG2K-EphA2 peptide and characterized for physicochemical properties, binding assay, cytotoxicity, cellular uptake studies, drug release and pharmacokinetic parameters...

BACKGROUND: Cigarette smoking is a tough addiction to break. Therefore, improved approaches to smoking cessation are necessary. The electronic-cigarette (e-Cigarette), a battery-powered electronic nicotine delivery device (ENDD) resembling a cigarette, may help smokers to remain abstinent during their quit attempt or to reduce cigarette consumption. Efficacy and safety of these devices in long-term smoking cessation and/or smoking reduction studies have never been investigated. METHODS: In this prospective proof-of-concept study we monitored possible modifications in smoking habits of 40 regular smokers (unwilling to quit) experimenting the 'Categoria' e-Cigarette with a focus on smoking reduction and smoking abstinence...

INTRODUCTION: Cystatin C could be a relevant residual glomerular filtration rate marker during hemodialysis (HD), and a high cytokine plasma (p) rate is associated with an increase in mortality during sepsis. To the best of our knowledge, cytokines and cystatin C kinetics during and after HD during sepsis have never been studied. In this study, we described p cytokines and cystatin C variations during and after hemodialysis in septic-shock patients with acute kidney injury (AKI). METHODS: Ten patients, from two tertiary ICUs, with septic shock-related AKI, according to RIFLE class F, were studied...

OBJECTIVES: To measure the short-term effects of an electronic nicotine delivery device ("e cigarette", ENDD) on desire to smoke, withdrawal symptoms, acceptability, pharmacokinetic properties and adverse effects. DESIGN: Single blind randomised repeated measures cross-over trial of the Ruyan V8 ENDD. SETTING: University research centre in Auckland, New Zealand. PARTICIPANTS: 40 adult dependent smokers of 10 or more cigarettes per day...

The biosynthetic gene cluster for the 17 aa peptide antibiotic enduracidin has been cloned and sequenced from Streptomyces fungicidicus ATCC 21013. The 84 kb gene cluster contains 25 ORFs and is located within a 116 kb genetic locus that was fully sequenced. Targeted disruption of non-ribosomal peptide synthetase (NRPS) genes in the cluster abolished enduracidin production and confirmed function. The cluster includes four genes, endA-D, encoding two-, seven-, eight- and one-module NRPSs, respectively, and includes unique modules for the incorporation of citrulline and enduracididine...
