OBJECTIVES We sought to investigate the acute hemodynamic effects of graded balloon dilation atrial septostomy (BDAS) and to define the long-term impact of this procedure on New York Heart Association functional class and survival in adult patients with primary pulmonary hypertension (PPH). BACKGROUND Current treatment strategies for patients with severe(More)
To through light on the mechanisms underlying the stimulation and persistence of glial cell activation in Parkinsonism, we investigate the function of IFN-γ and TNF-α in experimental models of Parkinson’s disease and analyze their relation with local glial cell activation. It was found that IFN-γ and TNF-α remained higher over the years in the serum and CNS(More)
Increasing experimental and neuropsychological evidence indicates that the cerebellum of humans and other mammals, traditionally associated with motor control, is implicated in a variety of cognitive and emotional functions. For example, the cerebellum has been identified as an essential structure in different learning processes, ranging from simple forms(More)
AIMS Mice and nonhuman primates administered with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) represent elective experimental models of Parkinsonism, in which degeneration of the nigrostriatal dopaminergic pathway is associated with prominent neuroinflammation, characterized by activated microglia and astrocytes in both substantia nigra (SN) and(More)
BACKGROUND The prognosis of patients with primary pulmonary hypertension (PPH) remains a major problem for the planning and assessment of therapeutic interventions. The objectives of this study were (1) to characterize mortality in a Mexican population of patients with PPH and to investigate factors associated with survival and (2) to test the applicability(More)
A nationwide community-based survey for Helicobacter pylori infection had not been done. This study sought to determine the seroprevalence of infection in Mexico, and the socioeconomic and demographic variables that are risk factors for infection. The survey assessed 11,605 sera from a sample population representing persons ages 1-90 years from all(More)
BACKGROUND The electronic Schizophrenia Treatment Adherence Registry (e-STAR) is a prospective, observational study of patients with schizophrenia designed to evaluate long-term treatment outcomes in routine clinical practice. METHODS Parameters were assessed at baseline and at 3 month intervals for 2 years in patients initiated on risperidone long-acting(More)
In mammals and birds different pallial forebrain areas participate in separate memory systems. In particular, the hippocampal pallium is implicated in spatial memory and temporal attribute processing, whereas the amygdalar pallium is involved in emotional memory. Here we analyze the involvement of teleost fish lateral and medial pallia, proposed as(More)
The Saccharomyces cerevisiae ynl294cDelta (rim21Delta) mutant was identified in our lab owing to its moderate resistance to calcofluor, although it also displayed all of the phenotypic traits associated with its function as the putative sensor (Rim21p) of the RIM101 pathway. rim21Delta also showed moderate hypersensitivity to sodium dodecyl sulfate,(More)
We describe the clinical, radiologic, functional, and pulmonary hemodynamic characteristics of a group of 30 nonsmoking patients with a lung disease that may be related to intense, long-standing indoor wood-smoke exposure. The endoscopic and some of the pathologic findings are also presented. Intense and prolonged wood-smoke inhalation may produce a chronic(More)
