Endoglin (CD105) and VEGF as potential angiogenic and dissemination markers for colorectal cancer.

Background: Colorectal cancer (CRC) is an important current problem concerning public health due to its high incidence and mortality. Advances in molecular and cellular knowledge and the detection of new disease biomarkers are very important to improve prognosis, prediction, and early diagnosis. In this study, we aimed to analyze the gene and protein expression levels of two angiogenic markers, VEGF and soluble Endoglin, during different tumor stages as well as at different stages of cancer treatment, to predict the diagnosis and evolution of colon and rectal cancer.

The Efflux Pump MexXY/OprM Contributes to the Tolerance and Acquired Resistance of Pseudomonas aeruginosa to Colistin.

The intrinsic resistance of to polymyxins in part relies on the addition of 4-amino-4-deoxy-l-arabinose (Ara4N) molecules to the lipid A of lipopolysaccharide (LPS), through induction of operon () expression. As demonstrated previously, at least three two-component regulatory systems (PmrAB, ParRS, and CprRS) are able to upregulate this operon when bacteria are exposed to colistin. In the present study, gene deletion experiments with the bioluminescent strain PAO1:: showed that ParRS is a key element in the tolerance of to this last-resort antibiotic (i.

Assessment of craniofacial hyperhidrosis and flushing by sphenopalatine blockade - a randomized trial.

Background: Craniofacial hyperhidrosis (CFH) and flushing express nervous system autonomic dysfunction. Available reference treatments lack good compliance. The study objective was to investigate variations of CFH/flushing after two methods of sphenopalatine ganglion (SPG) blockade.

Structural similarity index family for image quality assessment in radiological images.

The structural similarity index (SSIM) family is a set of metrics that has demonstrated good agreement with human observers in tasks using reference images. These metrics analyze the viewing distance, edge information between the reference and the test images, changed and preserved edges, textures, and structural similarity of the images. Eight metrics based on that family are proposed.
