Households in eleven geographically and ethnically distinct areas in Loreto, Peru, were interviewed about their knowledge and use of plants, for the treatment of malaria and leishmaniasis. The survey resulted in 988 use records representing 118 plant-taxa for malaria and 289 use-records representing 85 plant-taxa for leishmaniasis. In both cases the 10 most(More)
Patients with chronic obstructive pulmonary disease are generally subjected to multiple regimens of antimicrobial treatment. The development of high-level levofloxacin resistance (i.e., a minimum inhibitory concentration >8 mu g/mL) in 8 patients whose previous pneumococcal isolates showed susceptibility is described. Molecular methods were used to(More)
The Spain(14)-5 international multiresistant clone was initially described as resistant to penicillin, tetracycline, chloramphenicol and trimethoprim/sulfamethoxazole. In Gipuzkoa, Spain, Streptococcus pneumoniae isolated from 16 patients, and determined by PFGE and multilocus sequence typing to belong to the Spain(14)-5 clone, showed further resistance to(More)
In-stent restenosis (ISR) after carotid angioplasty and stenting is becoming evident as more patients undergo carotid stenting and duplex scan surveillance. While redo endovascular therapy has been immediately successful, recurrent stenosis remains a problem. The ideal management of ISR has not been determined. Three cases of symptomatic ISR that were(More)
OBJECTIVE To analyse the molecular structure of several antimicrobial resistance determinants in isolates of the Spain(14)-5 clone to better understand its emergence and spread. METHODS The distinct genes and mechanism of resistance to penicillin, erythromycin, clindamycin, tetracycline, chloramphenicol and trimethoprim were studied in an apparently(More)
OBJECTIVE To study the characteristics and the evolution through time of a single Streptococcus pneumoniae multidrug-resistant international clone. METHODS From 1981 to 2002, the presence of the multidrug-resistant Spain14-5 clone was studied among the 4201 S. pneumoniae isolated in Gipuzkoa (northern Spain). RESULTS Overall, 93 isolates belonging to(More)
More than 50 years ago connectionist systems (CSs) were created with the purpose to process information in the computers like the human brain (McCulloch & Pitts, 1943). Since that time these systems have advanced considerably and nowadays they allow us to resolve complex problems in many disciplines (classification, clustering, regression, etc.). But this(More)
The importance of astrocytes, one part of the glial system, for information processing in the brain has recently been demonstrated. Regarding information processing in multilayer connectionist systems, it has been shown that systems which include artificial neurons and astrocytes (Artificial Neuron-Glia Networks) have well-known advantages over identical(More)
