The frequencies of blood groups, Rh and HLA antigens were studied in a series of patients with paracoccidioidomycosis as well as in control subjects. Statistical analysis of the results showed that only 2 antigens (HLA-A9 and HLA-B13) had a significantly increased frequency among patients with paracoccidioidomycosis compared with healthy controls. Among(More)
The possible relationship between erythrocyte antigens and the presence of malaria infection by P. vivax and P. falciparum was sought in four different ethnic groups of two departments of Colombia. Malaria infection by P. falciparum was found in 91.4% of malaria infected blacks. No significant differences were found between the presence of malaria infection(More)
✴ Characterization of the Probabilistic Volumetric Models (PVM) as a new representation for 3-d scene understanding. ✴ The first evaluation of the performance of several local shape descrip-tors extracted from the PVM in terms of accuracy for object classification. ✴ Histogram-based descriptors are of particular interest as they are the most popular and(More)
BACKGROUND Attention-deficit/hyperactivity disorder (ADHD) comorbid with oppositional defiant disorder (ODD) or conduct disorder (CD) and substance abuse/dependence seems to represent a specific subset within the phenotypic ADHD spectrum. METHODS We applied complex segregation and linkage analyses in a set of multigenerational families densely segregating(More)
Serum electrophoresis patterns and various measures of specific and non-specific immune competence were determined in 16 patients with paracoccidioidomycosis, at time of diagnosis and 6 months after therapy. The results were compared with those furnished by the study of 16 control subjects, matched by age and sex. Once treated, the patients approached(More)
Diarrhea is a major cause of morbidity and discomfort for patients undergoing high-dose chemotherapy and autologous peripheral blood stem cell transplantation (APBSCT). There are multiple causes of diarrhea in patients undergoing transplantation including antineoplastic chemotherapy, antimicrobials and infection, including Clostridium difficile as the most(More)
The worldwide resurgence of malaria has become a major public health problem. New methods of controlling the vectors of the disease are required, and we therefore studied the biological control of Anopheles albimanus by Romanomermis culicivorax in Colombia. The investigation was carried out in El Valle and Nuquí, two towns on the northern Pacific coast of(More)
This double-blind study is based on the treatment of 75 adult male patients suffering from Plasmodium falciparum malaria in Medellín, Colombia, a city in which there is no malaria transmission. The patients, who came from regions with high resistance to antimalarials, were divided into three groups receiving single-dose treatment as follows: a combination(More)
—This paper presents a novel framework for surface reconstruction from multi-view aerial imagery of large scale urban scenes, which combines probabilistic volumetric modeling with smooth signed distance surface estimation, to produce very detailed and accurate surfaces. Using a continuous probabilistic volumetric model which allows for explicit(More)
