Soil erosion is a global issue that threatens food security and causes environmental degradation. Management of water erosion requires accurate estimates of the spatial and temporal variations in the erosive power of rainfall (erosivity). Rainfall erosivity can be estimated from rain gauge stations and satellites. However, the time series rainfall data that has a high temporal resolution are of...

∗ Autor para correspondência. Correio eletrónico: [email protected] (A.R. Araújo). Na radiografia de tórax observou-se cardiomegalia, com índice cardiotorácico de 60%. O eletrocardiograma mostrou ondas Q > 3 mm em DI, aVL e V7 e inversão da onda T de V5-V7, padrão sugestivo de enfarte do miocárdio. O ecocardiograma transtorácico revelou dilatação e disfunção global do ventrículo esqu...

Autoclaved distilled water samples were inoculated with L. monocytogenes strain V7 and strain VPH-1, and incubated aerobically, at 30 C for 48 hours. Each strain was tested individually, and growth curves were determined at 1, 2, 3, 4, 5, 21, 24, and 48 hours. The growth or survival of L. monocytogenes was similar for both strains, with survivors at 24 hour-incubation. The microbicidal activity...

In the current study, we investigated the nature and role of CD44 variant isoforms involved in endothelial cell (EC) injury and tumor cell cytotoxicity mediated by IL-2-activated killer (LAK) cells. Treatment of CD44 wild-type lymphocytes with IL-2 led to increased gene expression of CD44 v6 and v7 variant isoforms and to significant induction of vascular leak syndrome (VLS). CD44v6-v7 knockout...

OBJECTIVES This study was designed to examine whether ST segment elevation in posterior chest leads (V7 to V9) during acute inferior myocardial infarction (MI) identifies patients with a concomitant posterior infarction and whether these patients might benefit more from thrombolysis. BACKGROUND Because the posterior wall is faced by none of the 12 standard electrocardiographic (ECG) leads, th...

Spaceborne inferences of cloud microstructure and precipitation-forming processes with height have been used to investigate the effect of ingested aerosols on clouds and to integrate the findings with past cloud physics research. The inferences were made with a method that analyzes data from NOAA/AVHRR and TRMM/VIRS sensors to determine the effective radius of cloud particles with height. In ad...

Variant CD44 has recently been shown to serve as a metastasis marker in human breast cancer. Certain variant epitopes on primary tumors predict poor survival probabilities for the patients. In this study, immunohistochemical analysis of 16 uterine cervical carcinomas showed strong expression of several CD44 variant epitopes in all samples. In normal cervical epithelia from 5 patients, expressio...

Using FORTE photodiode detector (PDD) observations of lightning, we have determined the geographic distribution of nighttime flash rate density. We estimate the PDD flash detection efficiency to be 62% for total lightning through comparison to lightning observations by the TRMM satellite’s Lightning Imaging Sensor (LIS), using cases in which FORTE and TRMM viewed the same storm. We present here...
