We used the Enhanced Vegetation Index (EVI) from MODIS to scale evapotranspiration (ETactual) over agricultural and riparian areas along the Lower Colorado River in the southwestern US. Ground measurements of ETactual by alfalfa, saltcedar, cottonwood and arrowweed were expressed as fraction of potential (reference crop) ETo (EToF) then regressed against EVI scaled between bare soil (0) and ful...

Dentato-rubral and pallido-luysian atrophy (DRPLA) is one of the family of neurodegenerative diseases caused by expansion of a polyglutamine tract. The drpla gene product, atrophin-1, is widely expressed, has no known function or activity, and is found in both the nuclear and cytoplasmic compartments of neurons. Truncated fragments of atrophin-1 accumulate in neuronal nuclei in a transgenic mou...

The role of autophagy during leukemia treatment is unclear. On the one hand, autophagy might be induced as a prosurvival response to therapy, thereby reducing treatment efficiency. On the other hand, autophagy may contribute to degradation of fusion oncoproteins, as recently demonstrated for promyelocytic leukemia-retinoic acid receptor α and breakpoint cluster region-abelson, thereby facilitat...

There are few suitable techniques available to sterilize biodegradable polyester three-dimensional tissue engineering scaffolds because they are susceptible to degradation and/or morphological degeneration by high temperature and pressure. We used a novel polyllactide-co-glycolide) scaffold (Osteofoam) to determine the optimal sterilization procedure--i.e. a sterile product with minimal degrada...

A evapotranspiração de referência (ETo) é importante para a agricultura irrigada e sua relação com o Kc da cultura determina Evapotranspiração (ETc). Organização das Nações Unidas Alimentação Agricultura (FAO) determinou como padrão método Penman Monteith estimativa ETo, porém existem diferentes fórmulas empíricas tal aplicação, sendo assim presente trabalho tem objetivo avaliar referencia por ...

The development of new reference evapotranspiration (ETo) methods hold significant promise for improving our quantitative understanding of climatic impacts on water loss from the land to the atmosphere. To address the challenge of estimating ETo in tropical and subtropical regions where direct measurements are scarce we tested a new method based on geographical patterns of extraterrestrial radi...

We report that DNA damage induced by topoisomerase inhibitors, including etoposide (ETO), results in a potent block to HIV-1 infection in human monocyte-derived macrophages (MDM). SAMHD1 suppresses viral reverse transcription (RT) through depletion of cellular dNTPs but is naturally switched off by phosphorylation in a subpopulation of MDM found in a G1-like state. We report that SAMHD1 was act...

A 43-year-old man was diagnosed with AML with cellular maturation (AML-M2) according to the French-American-British classification criteria. A cytogenetic study with a G-banding method was initially reported as 45,X,-Y. However, dual-color, dual-fusion fluorescence in situ hybridization (FISH) with probes for the AML1 and the ETO genes showed an unusual pattern of signals, presenting one fusion...

Se analizó la diferencia entre tasa diaria de evapotranspiración referencia (ETo), que el método Penman-Monteith (PM) calcula con conjunto completo variables meteorológicas y obtenida utilizando solo registros térmicos una velocidad superficial (u2) constante 2 m s-1 (PMxn), empleando información meteorológica las estaciones Río Cuarto Aero (RC), Marcos Juárez (MJ), Pilar Observatorio (PI) Vill...
