Dos modos de ver y sentir el Perú: las propuestas estéticas y culturales enfrentadas de José María Arguedas y Mario Vargas Llosa

: José María Arguedas y Mario Vargas Llosa, dos de los escritores más importantes del Perú del siglo XX, representan, a su vez, dos modos divergentes y contrapuestos de entender la realidad del país andino. Este estudio abordará las antagónicas propuestas estéticas y culturales de ambos autores a través del análisis de los principales ejes de la narrativa arguediana y del ensayo La utopía arcaica de Vargas Llosa y las planteará como una proyección de la conflictividad socio-cultural que inauguró la conquista y como un reflejo de las distintas respuestas que originó el movimiento indigenista en el Perú.

Notes of Lutzomya (Helcocyrtomyia) trinidadensis (Newstead, 1922) (Diptera: Psychodidae-Phlebotominae)

A re-examination of the syntypes of Lutzomyia (Helcocyrtomyia) trinidadensis (Newstead,1922) in the British Museum (Natural History) led to the designation of a lectotype male and a paralectotype female, and both are now described. On the basis of these descriptions, the status of forms previously placed in synonymy with L. trinidadensis is discussed.

La persistencia de la memoria: violencia política, memoria histórica y testimonio en Antígona, de José Watanabe y el Grupo Yuyachkani

Partiendo de una concepción del teatro como espacio político por excelencia, se analizan las relaciones entre este, el trauma colectivo y la memoria histórica en un contexto de violencia político a partir del estudio de dos montajes de Antígona, de José Watanabe y el Grupo Yuyachkani: su estreno en Lima (2000) y su reposición en Huanta (2001). El análisis del texto en sus contextos originales de recepción permite reflexionar desde nuevas perspectivas sobre un problema relacionado con el conflicto armado interno ocurrido en el Perú entre los años 1980 y 2000: la responsabilidad ética y política de los sobrevivientes

Frequency of human toxocariasis in Jos, Plateau State, Nigeria

The enzyme-linked immunosorbent assay (Elisa) was used to examine sera of 104 children and adults in Jos, Plateau State, Nigeria for anti-toxocaral antibodies, out of which 31 (29.8%) were reactive. The seropositive rates were 30.4% for adults, 29.6% for children, 34% for females and 25.9% for males. However, the differences were not significant by age and sex. A highly significant association (p < 0.001) was observed between seropositivity and geophagia but none between seropositivity and dog ownership (p > 0.05).

Estudio del ecosistema urbano de San José. Protocolo de monitoreo de aves y naturalización del Parque La Sabana

El papel de la ciudad en el futuro de la humanidad será transcendente, y es que el crecimiento actual de los espacios urbanos tiende, en general, a desbordar el sitio original de las ciudades, abarcando territorios cada vez más extensos y discontinuos. Y por este motivo es de vital importancia el estudio de la ciudad y de su entorno, el cual es sinónimo de ecosistema urbano. En el siguiente estudio se evalúa el ecosistema urbano de San José, capital de Costa Rica, dando énfasis en las zonas verdes presentes, en las relaciones con los ecosistemas naturales circundantes y como mejorar su capacidad ecológica. Por este motivo se ha analizado un proceso de rearborización en el Parque Metropolitano La Sabana, principal nódulo de carga de la trama urbana. Este esfuerzo de naturación dotará al parque de una mayor naturalización, con lo que se espera un aumento de la biodiversidad faunística. Para conocer estos cambios se crea un programa de monitoreo de aves con su respectivo protocolo.

Prevalence of hepatitis-B surface antigen among blood donors and human immunodeficiency virus-infected patients in Jos, Nigeria

Information is very scarce on the prevalence of hepatitis-B virus (HBV) infection among blood donors and patients with human immunodeficiency virus (HIV) infection in Nigeria. Hepatitis-B surface antigen (HBsAg) ELISA was used to determined the prevalence of HBsAg among 175 blood donors (aged 20-40 years) and 490 HIV-infected patients (aged 17-60 years) in Jos, Nigeria. Twenty-five (14.3%) of the blood donors and 127 (25.9%) of the HIV-infected individuals were HBsAg seropositive, indicating a higher HBV infection among HIV-infected persons than among healthy blood donors. A slightly higher HBsAg seroprevalence was recorded in the males (14.6%) than females (12.9%) of the blood donors. Among the HIV-infected patients, the males had considerably higher HBsAg seroprevalence than the females (31.8 vs 22.1%) with the highest prevalence of HBsAg occurring in the 51-60 years age group (44%), followed by those of 31-40 years (28.2%). Results confirmed the high endemicity of HBV infection in Jos, Nigeria and the significantly greater prevalence of HBV infection among HIV -infected patients than among blood donors.

Detection and differentiation of Cryptosporidium by real-time polymerase chain reaction in stool samples from patients in Rio de Janeiro, Brazil

This study reports the first genetic characterisation of Cryptosporidium isolates in Brazil using real-time polymerase chain reaction (RT-PCR). A total of 1,197 faecal specimens from children and 10 specimens from human immunodeficiency virus-infected patients were collected between 1999-2010 and screened using microscopy. Forty-eight Cryptosporidium oocyst-positive isolates were identified and analysed using a generic TaqMan assay targeting the 18S rRNA to detect Cryptosporidium species and two other TaqMan assays to identify Cryptosporidium hominis and Cryptosporidium parvum. The 18S rRNA assay detected Cryptosporidium species in all 48 of the stool specimens. The C. parvum TaqMan assay correctly identified five/48 stool samples, while 37/48 stool specimens were correctly amplified in the C. hominis TaqMan assay. The results obtained in this study support previous findings showing that C. hominis infections are more prevalent than C. parvum infections in Brazil and they demonstrate that the TaqMan RT-PCR procedure is a simple, fast and valuable tool for the detection and differentiation of Cryptosporidium species.
