The tropical glaciers of the Cordillera Blanca, Peru, are rapidly retreating, resulting in complex impacts on the hydrology of the upper Río Santa watershed. The effect of this retreat on water resources is evaluated by analyzing historical and recent time series of daily discharge at nine measurement points. Using the Mann–Kendall nonparametric statistical(More)
Little information exists about the association of anti-SSA/Ro60 and anti-Ro52/TRIM21 with systemic lupus erytematosus (SLE) features. In this work, we analysed the associations of both anti-Ro reactivities with clinical and immunological manifestations in 141 SLE patients. Photosensitivity and xerophtalmia/xerostomia were found to be positively associated(More)
OBJECTIVE To investigate the relative amounts of Th17 and Th1 cells present in SLE patients and the possible effects of treatments or disease features on these populations. METHODS Peripheral blood mononuclear cells were collected from 75 SLE patients and 19 healthy controls and the proportion of Th17 and Th1 populations were assessed by flow cytometry(More)
OBJECTIVE The aim of this study was to investigate the endothelial progenitor cell population in SLE and early RA patients and its potential relationships with disease features and cytokine serum levels. METHODS Endothelial progenitor cells (EPCs), mature EPCs (mEPCs) and endothelial cells (ECs) were measured in peripheral blood samples from 83 SLE and 85(More)
Our understanding of the annual life-cycle movements of small migratory birds has advanced rapidly with the advent of light-weight geographical positioning devices (i.e., geolocators), yet the effects of geolocators on reproduction and survival have not been adequately quantified. We tested for impacts of attaching a 1-g geolocator (using a harness around(More)
Antimalarial agents have been widely used as disease-modifying antirheumatic drugs in the treatment of systemic lupus erythematosus (SLE) and other rheumatological diseases, although their mechanism of action has not yet been fully defined. It is known, however, that effective response to treatment is variable among patients. Thus, the identification of(More)

Esta especie se encuentra situada dentro(More)
To all who helped me get this far, thank you for believing in me. ABSTRACT Water supply problems are ever increasing as populations grow and supplies are finite. Policy makers have many tools at their disposal to assist in their management of limited resources. One set of tools that are gaining popularity are hydrologic models of varying levels of(More)
