Tuberculosis and atopy: A study in an endemic area [PDF]

open access: yesRespiratory Medicine, 2006
Atopy is expected to be less frequent and milder in patients with early exposure to bacterial infections because of regulatory immune mechanisms. The definition of the hygiene hypothesis and most of the related studies have been performed in children.

Mapping phylogenetic endemism in R using georeferenced branch extents

open access: yesSoftwareX, 2015
Applications are needed to map biodiversity from large-scale species occurrence datasets whilst seamlessly integrating with existing functions in R. Phylogenetic endemism (PE) is a biodiversity measure based on range-restricted phylogenetic diversity (PD)

Psittacosis in a highly endemic area in Italy [PDF]

open access: yesEpidemiology and Infection, 1987
SUMMARYIn one locality in Italy where the incidence of psittacosis has increased rapidly since 1980, a hospital-based study and a seroepidemiological survey were carried out in order to define the clinical and epidemiological features of psittacosis in that area.Registers of the Virology Unit of the University of Ancona, Italy, were reviewed and all ...

Odonata Recorded in the Buffer Zone of Mt. Hamiguitan Range Wildlife Sanctuary with Remarks on the Distribution of Endangered Risiocnemis antoniae in Davao Oriental Philippines

open access: yesNotulae Scientia Biologicae, 2018
Mt. Hamiguitan Range Wildlife Sanctuary is both a UNESCO and ASEAN recognised heritage site. There is a current move to expand the site by expanding the buffer zone. This area unfortunately is poorly studied in terms of its biodiversity.
