INTRODUCTION: Tobacco advertising can create false beliefs about health harms that are reinforced by product design features. Reduced nicotine content (RNC) cigarettes may reduce harm, but research has not addressed advertising influences. This study examined RNC cigarette advertising effects on false harm beliefs, and how these beliefs - along with initial subjective ratings of RNC cigarettes - affect subsequent smoking behaviors. We further explored whether subjective ratings moderate associations between false beliefs and behavior...

In the last two decades, an enormous expansion of evidence has been produced in upper airway research. When writing the first EPOS document in 2005 only 5 RCT per year were performed in the area of CRS, in 2007 this changed to 25 per year and it became even higher in the recent years. Randomized Controlled Trials (RCTs) are the "gold standard" for evaluating treatment outcomes providing information on treatments "efficacy". To make life easier for clinicians, systematic reviews and meta-analysis further condense the available evidence...

Despite many studies looking at the distribution of myosin heavy chain (MHC) isoforms across a transverse section of muscle, knowledge of MHC distribution along the longitudinal axis of a single skeletal muscle fiber has been relatively overlooked. Immunocytochemistry was performed on serial sections of rat extensor digitorum longus (EDL) muscle to identify MHC types I, IIA, IIX, IIY and IIB. Sixteen fascicles which contained a total of 362 fibers were randomly and systematically sampled from the 3 EDL muscles...

The purpose of this article is to analyze longitudinal trends in locoregional therapy (LRT) use and review locoregional therapy's role in the management of hepatocellular carcinoma prior to orthotropic liver transplantation Porrett et al. (2006) . LRT has a role in both bridge to transplantation and downstaging of patients not initially meeting Milan or UCSF Criteria. Due to the lack of randomized controlled trials, no specific bridging LRT modality is recommended over another for treating patients on the waiting list, however each modality has unique and patient-specific advantages...

PURPOSE: Testing for antibodies to Chlamydia trachomatis has potential as a surveillance tool. Our evaluation compares lateral flow assays (LFAs) during surveillance surveys in Nepal with Multiplex bead array (MBA). Fifty children were randomly sampled from each of 15 random clusters in two districts of Nepal. Finger prick blood samples were collected from 1509 children and tested onsite for anti-Pgp3 antibodies by LFA. The LFA was read at 30min as negative, positive, or invalid. Tests results were also rated as difficult to read ("equivocal")...

OBJECTIVES: Rheumatoid arthritis (RA) is associated with an increased risk of lymphoma linked to activity of the disease. Immunosuppressive drugs have been suspected to induce an additional risk. Since, NK cells have been recently shown to participate to anti-lymphoma immunosurveillance, we aimed to assess if anti-TNF might impact their anti-lymphoma activity. METHODS: NK cells have been assessed ex vivo in patients with RA treated with methotrexate (MTX) with or without anti-TNF...
