Abstract 2+We present a methodology for the use of sulphur as global metallicity tracer in galaxies, allowing performing complete abundance analysis using only red-to-near-infrared spectral region. We have applied it to compilation high-quality data split into two samples: H ii regions (DHR) spiral and irregular dwarf galaxies dominated by strong starburst (H Gal). Sulphur abundances been deriv...
Abstract Purpose Family involvement is a key element of Domestic Homicide Review (DHR), the form Violence Fatality (DVFR) found in England and Wales. framed as having dual purposes: first, benefit to DHRs, enabling fuller picture victims’ experiences; second, families themselves, notably therapeutic or cathartic opportunity. However, these purposes have been little considered. This conceptual a...
Increased production of oxidants subsequent to phagocyte stimulation has been associated with tissue damage in lung inflammatory disorders. The overall oxidative burden of the lung may vary with inflammatory cell composition. Flow cytometry using three different dyes, dihydroethidium (DHE), dichlorofluorescein diacetate (DCFH-DA) and dihydrorhodamine 123 (DHR), all compounds that by interaction...
Although the negative effect of excessive alcohol consumption on later stressful events has long been recognized, pathophysiological mechanisms are incompletely understood. We examined possible roles of oxygen radicals and glutathione content in mesenteric venules of chronically ethanol-fed rats exposed to ischemia-reperfusion. Changes in microvascular hemodynamics, such as red blood cell (RBC)...
Mammalian DOCK180 protein and its orthologues Myoblast City (MBC) and CED-5 in Drosophila and Caenorhabditis elegans, respectively, function as critical regulators of the small GTPase Rac during several fundamentally important biological processes, such as cell motility and phagocytosis. The mechanism by which DOCK180 and its orthologues regulate Rac has remained elusive. We report here the ide...
Two contrasting theories have been proposed to explain the mechanistic basis of short term memory. One theory posits that short term memory is represented by persistent neural activity supported by reverberating feedback networks. An alternate, more recent theory posits that short term memory can be supported by feedforward networks. While feedback driven memory can be implemented by well descr...
Steatotic livers are highly susceptible to I/R (ischaemia/reperfusion) injury and, therefore, the aim of the present study was to evaluate the in vivo effect of NAC (N-acetylcysteine) on hepatic function in the early and initial late phase of warm liver I/R injury in steatotic rabbits. Twelve New Zealand White rabbits were fed a high-cholesterol (2%) diet. The control group (n=6) underwent loba...
OBJECTIVE To compare, retrospectively, the values of maximum heart rate (MHR) and the decrease of the heart rate at the first minute of recovery, which were obtained in an exercise test (ET) performed in two different ergometers and at different moments. METHODS Sixty individuals (from 29 to 80 years old), submitted to cardiopulmonary ET in a cycle of lower limbs (CLL) in our laboratory and w...
Drug hypersensitivity reactions (DHRs) are a matter of great concern, both for outpatient and in hospital care. The evaluation of these patients is complex, because in vivo tests have a suboptimal sensitivity and can be time-consuming, expensive and potentially risky, especially drug provocation tests. There are several currently available in vitro methods that can be classified into two main g...
The Multi-angle Imaging Spectroradiometer (MISR) and Moderate Resolution Imaging Spectroradiometer (MODIS) onboard the National Aeronautics and Space Administration (NASA)’s Earth Observing System (EOS) Terra satellite are crucial for generation of other products such as the Fraction of Photosynthetically Active Radiation (FPAR) and Leaf Area Index (LAI). The analysis reported here compares the...
