[ROWING AGAINST THE CURRENT].

At Lalonde we know that the determinants that most influence the health of the population are lifestyle, genetics and the environment. Health represents only 10% and is the determinant that consumes the most resources. It has been shown that a salutogenic approach focused on the social determinants of health and the support of public policies to improve the environment are more efficient in the long term than medicine focused on hospitals, technology and super-specialization.

Maximum tumor-absorbed dose measured by voxel-based multicompartmental dosimetry as a response predictor in yttrium-90 radiation segmentectomy for hepatocellular carcinoma.

Objective: Advances in hepatic radioembolization are based on a selective approach with radical intent and the use of multicompartment dosimetric analysis. The objective of this study is to assess the utility of voxel-based dosimetry in the quantification of actual absorbed doses in radiation segmentectomy procedures and to establish cutoff values predictive of response.

Methods: Ambispective study in hepatocarcinoma patients treated with radiation segmentectomy.

Characterization of blaCMY-2 plasmids in Salmonella and Escherichia coli isolates from food animals in Canada.

One hundred thirty-four bla(CMY-2) plasmids from Salmonella and Escherichia coli strains from animals and food in Canada were characterized. Five plasmid groups were identified based on replicon type and restriction profiles. Three groups contained E.

Turning up the lights--fabrication of brighter SERRS nanotags.

Brighter SERRS nanotags ideal for improved SERRS imaging were prepared by the controlled addition of electrolyte producing a dimer enriched solution, which was incubated with a Raman reporter before being stabilised by a polyethylene glycol (PEG) shell.

Subinhibitory concentrations of tetracycline affect virulence gene expression in a multi-resistant Salmonella enterica subsp. enterica serovar Typhimurium DT104.

Treatment of salmonellosis with antibiotics is controversial and may prolong carriage and shedding. Therefore, this study sought to investigate if exposure to antimicrobials influences the expression of factors involved in virulence and host colonization. The effect of subinhibitory tetracycline treatment (16 microg/ml, 30 min) on a multi-drug resistant Salmonella Typhimurium DT104 strain was investigated using a targeted microarray.
