Background and Objectives: Iran is classically located in the Palearctic zoogeographic zone, but southern pasts of Iran are drastically different from other parts in terms of fauna and flora. Nowadays, considering the technological advances and the ability to locate the zone border using aerial photos, and the need for comparing the prevalence of the diseases in different locations, it is neces...
Vascular diseases of the brain are the second reason of the death and the first cause of morbidity and disability worldwide. In tropical areas stroke has some particular features related to the nature of torrid zones. There are some special causes of the stroke, mainly infectious, although some of them are non-infectious. The most important etiologies are malaria, tuberculosis, cysticercosis, s...

We use two methodologies, the least square dummy variables approach and the dynamic factor models, to decompose the labor productivity growth rate for a large sample of countries into common, i.e. global, and idiosyncratic, i.e. country, components. We find that country specific effects are much more important than common effects in explaining labor productivity. The interesting result is that,...

Published data and analyses from temperate and tropical aquatic systems are used to summarize knowledge about the potential impact of land-use alteration on the nitrogen biogeochemistry of tropical aquatic ecosystems, identify important patterns and recommend key needs for research. The tropical N-cycle is traced from pre-disturbance conditions through the phases of disturbance, highlighting ma...
BACKGROUND Seasonal mortality differences have been reported in US hemodialysis (HD) patients. Here we examine the effect of seasons on mortality, clinical and laboratory parameters on a global scale. METHODS Databases from the international Monitoring Dialysis Outcomes (MONDO) consortium were queried to identify patients who received in-center HD for at least 1 year. Clinics were stratified ...
Landslides in tropical and sub-tropical regions are generally associated with weathered rock profiles which often possess chemical and mineralogical heterogeneities at materialand mineral-scales. Such heterogeneities reach a climax by the occurrences of oxyhydroxideand clayrich zones. Weakness and low permeability of these zones makes them ideal for the development of slip zones along which lan...
BACKGROUND Allergen exposure leads to allergen sensitization in susceptible individuals and this might influence allergic rhinitis (AR) phenotype expression. We investigated whether sensitization patterns vary in a country with subtropical and tropical regions and if sensitization patterns relate to AR phenotypes or age. METHODS In a national, cross-sectional study AR patients (2-70 y) seen b...
Species are unevenly distributed among genera within clades and regions, with most genera species-poor and few species-rich. At regional scales, this structure to taxonomic diversity is generated via speciation, extinction and geographical range dynamics. Here, we use a global database of extant marine bivalves to characterize the taxonomic structure of climate zones and provinces. Our analyses...
