Mild pancreatitis is a common complication of endoscopic retrograde cholangio-pancreatography (ERCP) and endoscopic sphincterotomy. Knowing that a bolus injection of natural somatostatin (SRIF) dramatically reduces pancreatic secretion, a study was conducted in 33 subjects undergoing invasive diagnostic procedures. A placebo (n = 16) or SRIF (n = 17; 4(More)
Th17 cells, a recently described subtype of CD4+ effector lymphocytes, have been linked to cell-mediated autoimmune and inflammatory diseases as well as to cardiovascular diseases. However, the participation of IL-17A in myocardial ischemic injury has not been clearly defined. We therefore conducted the present study to evaluate IL-17A and Th17-related(More)
AIM To evaluate the synergistic activity of antimicrobial drugs against lineages of methicillin-resistant Staphylococcus aureus (MRSA) carrying SCCmec IV. The biofilm production and related genes were also detected. METHODS AND RESULTS Forty two MRSA isolates were tested for biofilm production and related genes. Biofilm/biomass susceptibility to(More)
Next generation sequencing (NGS) technologies have arrived, changing research and infectious disease research into a new era, the "genomic era". Currently, the developed world is introducing NGS in a number of applications, including clinical diagnostics, epidemiology, and microbiology. In developing countries NGS is being progressively introduced.(More)

PURPOSE To compare the efficacy of nifedipine and fenoterol in the management of threatened preterm labor (TPL). METHODS A randomized and multicenter study assessing the tocolytic effect of nifedipine versus fenoterol in patients admitted to the participating maternity units with a diagnosis of TPL and a cost-savings study for economic assessment. For a(More)

Salmonella enterica can cause disease and mortality in calves. This pathogen is also a zoonosis that can be transmitted by animal contact or by food. The prevalence of Salmonella in dairy farms has been reported to range from 0 to 64%, and, due to the diversity of Salmonella serovars that can be circulating, Salmonella is an important concern for dairy(More)
Little is known about Salmonella serovars circulating in backyard poultry and swine populations worldwide. Backyard production systems (BPS) that raise swine and/or poultry are distributed across Chile, but are more heavily concentrated in central Chile, where industrialized systems are in close contact with BPS. This study aims to detect and identify(More)
