The epidemiology of amebiasis has dramatically changed since the separation of Entamoeba histolytica and Entamoeba dispar species, and the worldwide prevalence of these species has not been estimated until recently. The most cited data regarding prevalence, morbidity, or mortality due to amebiasis is the 1986 Walsh report, in which 100,000 deaths are(More)
This paper assembles a dataset comprising 1,565 banks in 20 Asian and Latin American countries during 1989-2001 and compares the response of the volume of loans, deposits, and bank-specific interest rates on loans and deposits, to various measures of monetary conditions, across domestic and foreign banks. It also looks for systematic differences in the(More)
This paper discusses initial findings that have resulted from ongoing work in the development of a platform for constructing and manipulating learning objects that include three-dimensional elements (3DLOs). We have produced a set of criteria for selecting appropriate immersive platforms and also have started a collection of 3DLOs, for which we have(More)
In accordance with the 1997 documents of the World Health Organization (WHO), amoebiasis is defined as the infection by the protozoan parasite Entamoeba histolytica with or without clinical manifestations. The only known natural host of E. histolytica is the human with the large intestine as major target organ. This parasite has a very simple life cycle in(More)
For over 30 years it has been established that the Entamoeba histolytica protozoan included two biologically and genetically different species, one with a pathogenic phenotype called E. histolytica and the other with a non-pathogenic phenotype called Entamoeba dispar. Both of these amoebae species can infect humans. E. histolytica has been considered as a(More)
Entamoeba histolytica calreticulin (EhCRT) is remarkably immunogenic in humans (90–100% of invasive amoebiasis patients). Nevertheless, the study of calreticulin in this protozoan is still in its early stages. The exact location, biological functions, and its role in pathogenesis are yet to be fully understood. The aim of the present work is to determine(More)
Amebiasis is an endemic disease and a public health problem throughout Mexico, although the incidence rates of amebic liver abscess (ALA) vary among the geographic regions of the country. Notably, incidence rates are high in the northwestern states (especially Sonora with a rate of 12.57/100,000 inhabitants) compared with the central region (Mexico City(More)
BACKGROUND Lipoprotein(a) [Lp(a)] is a known risk factor for cardiovascular disease, yet its influence on metabolic syndrome (MS) is still controversial. The purpose of this study was to assess the impact generated by this diagnosis in serum Lp(a) concentrations. MATERIALS AND METHODS A total of 1807 subjects of both genders (55.3% women and 44.7% men)(More)
BACKGROUND This study aimed to determine the frequency of Entamoeba histolytica and Entamoeba dispar infection in school children in the community of Tlaltizapan, in order to understand the dynamics of infection within the school and family spheres of this population. Amoebiasis is an unsolved public health problem and an endemic disease in Mexico. The(More)
