The aim of this work is to assess the evolution of caries and fluorosis prevalence and indices at 7 and 12 years of age in the Canary Islands through three cross epidemiological studies conducted in 1991, 1998 and 2006. The three studies followed a similar methodology, using the WHO diagnosis criteria and indications, except for the assessment of fluorosis, which was measured with the "Thylstru...

BACKGROUND Population genetic theory holds that oceanic island populations are expected to have lower levels of genetic variation than their mainland counterparts, due to founder effect after island colonization from the continent. Cistus monspeliensis (Cistaceae) is distributed in both the Canary Islands and the Mediterranean region. Numerous phylogenetic results obtained in the last years all...

Aim To explore the determinants of island occupancy of 48 terrestrial bird species in an oceanic archipelago, accounting for ecological components while controlling for phylogenetic effects. Location The seven main islands of the Canary archipelago. Methods We obtained field data on density, habitat breadth and landscape distribution in Tenerife, Fuerteventura and La Palma, trying to sample the...

Evolutionary molecular studies of island radiations may lead to insights in the role of vicariance, founder events, population size and drift in the processes of population differentiation. We evaluate the degree of population genetic differentiation and fixation of the Canary Islands blue tit subspecies complex using microsatellite markers and aim to get insights in the population history usin...

Article Outline Materials and Methods Conclusion References Vitae ED overcrowding has been gaining national attention in recent years. It is becoming apparent that, like the canary in the coal mine, ED conditions are emblematic of systemwide health care failures: too many patients, not enough room, inadequate resources, and

The ability to resolve closely spaced frequencies of two high-resolution AR spectral methods, the Burg's and Marple's approaches, is examined by using time series of coastal currents measured in waters of Canary Islands. We emphasise their usefulness to resolve tidal harmonic components with close frequencies and low frequency components.

Murine typhus and "murine-typhus-like" disease are reemerging infectious diseases. In Canary Islands (Spain), a rather distinct clinical pattern characterized by higher incidence of complications, especially renal damage (including acute failure and urinalysis abnormalities), is apparent and highly suggestive. It could be related to different strains of Rickettsia typhi or other cross-reactive ...
