This is a cross sectional study of 40 patients diagnosed with chronic rhinosinusitis using the Lanza Kennedy diagnostic criteria based on nasal endoscopy (NE), and on computer tomography (CT) of the paranasal sinuses. The purpose of the study is to demonstrate the effectiveness and limitations of CT, and NE in the assessment of chronic rhinosinusitis. This study shows that CT was superior in de...

It is well recognized that lower extremity peripheral arterial disease (PAD) is highly prevalent and results in significant cardiovascular mortality akin to cardiovascular disease.1 Among patients with PAD there is a broad range of clinical manifestations, with a third of patients having typical intermittent claudication (IC). The symptoms of lower extremity PAD, even in a stable nonlimb threat...

Strong infrared circular polarization resulting from dust scattering in reflection nebulae in the Orion OMC-1 star-formation region has been observed. Circular polarization at shorter wavelengths might have been important in inducing chiral asymmetry in interstellar organic molecules that could be subsequently delivered to the early Earth by comets, interplanetary dust particles, or meteors. Th...

We report X-ray results of the Chandra observation of Orion Molecular Cloud 2 and 3. A deep exposure of ∼ 100 ksec detects ∼ 400 X-ray sources in the field of view of the ACIS array, providing one of the largest X-ray catalogs in a star forming region. Coherent studies of the source detection, time variability, and energy spectra are performed. We classify the X-ray sources into class I, class ...

O Acordo SPS da OMC traz, em seu artigo 5.7, dispositivo que permite a adoção provisória de medidas (fito)sanitárias frente à insuficiência evidência científica. Aproxima-se, sem se confundir, com o princípio precaução, originário do Direito Ambiental, relativiza relação entre ciência e riscos uma forma mais ampla. Neste artigo, pergunta-se como possível evolução precaução no Internacional, apó...

Mycotoxins have become a serious issue in the animal feed industry and also affected aquaculture industry. can create health problems aquatic terrestrial animals, their presence agricultural products may result significant economic losses. To reduce impact of mycotoxins on Nile tilapia fry, two commercially available products—Organically Modified Clinoptilolite (OMC) multi-component mycotoxin d...
