PublicaciónForest dynamics of a sub-xerophilous vegetation formation in central Peru-Chanchamayo valley, Peru [Dinâmica florestal de uma formação vegetais sub-xerófila no valor de Chanchamayo, departamento Junin, Peru](Sociedade de Investigacoes Florestais, 2018)Studies about the complex processes of forest dynamics in pre-montane and montane forests (between 600 – 3000 m altitude) are rare. This study contributes to our knowledge on changes in the floristic composition and population dynamics of woody species in a sub-xerophilous formation immersed in the humid pre-montane and montane forests of Peru. In 2015 we re-measured trees with diameter at breast height equal or greater than10cm in a permanent plot established in 2009. We recorded 31 species of 25 families, with a Fisher’s Alpha diversity index of 7.5. The most abundant and dominant species (including Heteropterys intermedia, Physocalymma scaberrimum, Sapium glandulosum, Tachigali peruviana and Machaerium hirtum) represented 66.25% of all species in 2009 and 66.36% in 2015. The prevalence of these species and others ensures the maintenance of a characteristic seasonally dry forest formation within the census period (6.25 years). The dynamics of this forest, with a high rate of recruitment (3.82%) and a low rate of mortality (0.72%), show favorable conditions for the maintenance of this forest fragment. © 2018, Sociedade de Investigacoes Florestais.

PublicaciónNovel and known MYOC exon 3 mutations in an admixed Peruvian primary open-angle glaucoma population(National Library of Medicine, 2012)The aim of this study was to characterize a representative sample of the Peruvian population suffering open-angle glaucoma (OAG) with respect to the myocilin gene (MYOC) mutations, glaucoma phenotype, and ancestry for future glaucoma risk assessment.

PublicaciónIntestinal parasites of the grey fox (Pseudalopex culpaeus) in the central Peruvian Andes(National Library of Medicine, 1998)The intestines of 20 grey Peruvian foxes (Pseudalopex culpaeus) were examined for the presence of Echinococcus granulosus and other intestinal parasites. Echinococcus granulosus was not found in foxes but Taenia hydatigena and T. multiceps were found in 7 and 4 animals respectively. The grey fox may not be a suitable definitive host for E. granulosus. However, it may act as a sylvatic reservoir of T. hydatigena and T. multiceps in the central Peruvian Andes.

PublicaciónEtiology of acute pneumonia syndrome in beef cattle in Lima [Etiología del síndrome neumónico agudo en vacunos de engorde en Lima](Universidad Nacional Mayor de San Marcos, 2000)Clinical-, serological and pathological examinations were conducted on twenty feedlot cattle with acute pneumonia from the Department ofLima, in order to determine the etiology ofthe disease. Prior to sacrifice ali the animals were monitored for clinical signs and sera samples taken for serological testing. At postmortem, ali affected lungs were examined grossly and pathological samples were taken to identify viral agents by direct immunoflourescence and/or bacteriological isolation, as well as for histopathological studies.

Variedad morada (maíz morado) en artritis experimental en ratas](Instituto Nacional de Salud, 2018)Busca evaluar el efecto protector de Zea mays L. variedad morada (maíz morado) frente a la respuesta inflamatoria y daño osteoarticular en ratas con artritis experimental.
