Models of the evolution of parasite virulence have focused on computing the evolutionarily stable level of virulence favored by tradeoffs within a host and by competition for hosts, and deriving… (More)
Habitat preference behavior may play an important role in nonallopatric speciation. However, most examples of habitat preference contributing to differentiation within natural populations correspond… (More)
Quantitative ultrasound (QUS) assessment at the calcaneus has been found to be a safe and reliable method for evaluating skeletal status. In this study we have determined the normative QUS data in… (More)
To study the role of divergent selection in the differentiation of the two morphs in a hybrid zone of the intertidal snail Littorina saxatilis, we compared the strength of the divergent selection… (More)
BACKGROUND
Leukocyte infiltration is a common feature in renal biopsies from patients with acute poststreptococcal glomerulonephritis (APSGN). Cationic streptococcal erythrogenic toxin type B (ETB)… (More)
BACKGROUND
Previous reports have shown the presence of erythrogenic toxin type B (ETB), apoptosis, proliferation, and leukocyte infiltration in biopsies from patients with acute poststreptococcal… (More)
Agricultural livestock represents the main source of ammonia (NH3) in Europe. In recent years, reduction policies have been applied to reduce NH3 emissions. In order to estimate the impacts of these… (More)
BACKGROUND
Apoptosis is a mechanism of cellular death involved in the deletion of cells in hyperplasic processes which has been observed in proliferative glomerulonephritis. Patients with systemic… (More)
A new study to address the biosphere-atmosphere exchange of ammonia (NH3) with grasslands is applying a European transect to interpret NH3 fluxes in relation to atmospheric conditions, grassland… (More)
Vascular endothelial growth factor (VEGF) and its receptor (VEGFR) are overexpressed in the majority of renal cell carcinomas. This characteristic has supported the rationale of targeting VEGF-driven… (More)
