SARS-CoV-2 (COVID-19) infection is a current public health problem that has been shown to cause multiple complications, including pulmonary thromboembolism. The first presented case 59-year-old woman with history of COPD, paroxysmal atrial fibrillation and COVID-19 in September 2020, consultation December 2020 for atypical chest pain suspected PE, AngioCT vessels was performed negative emboli, ...

Regional control of blood flow is often suggested as a mechanism for fine thermoregulatory adjustments in snakes. However, the flow of blood to different body regions at various temperatures has never been visualized to confirm this mechanism. We used (99m)technetium-labelled macroaggregated albumin ((99m)Tc-MAA), a radioactive tracer, to follow the flow of blood through the bodies of garter sn...

Fast biodegradable (12 h < half-life < 48 h) radioactive labeled microspheres are needed for PET and SPECT lung perfusion and radiomicrosphere therapy planning. An emulsion method was used to create 30.1 ±4.8  μ m size range microspheres with biodegradable Chitosan glycol (CHSg). Microspheres were characterized and labeled with (99m)Tc or (68)Ga as an alternative to MAA in perfusion PET and SPE...

UNLABELLED Before (166)Ho radioembolization, a small batch of the same type of microspheres is administered as a scout dose instead of the conventional (99m)Tc-macroaggregated albumin ((99m)Tc-MAA). The (166)Ho scout dose provides a more accurate and precise lung shunt assessment. However, in contrast to (99m)Tc-MAA, an unintended extrahepatic deposition of this β-emitting scout dose could infl...

J Appl Physiol 106: 1986–1992, 2009. First published April 16, 2009; doi:10.1152/japplphysiol.01357.2007.—We have demonstrated that 50m-diameter arteriovenous pathways exist in isolated, healthy human and baboon lungs, ventila...

Key words: continuous ambulatory peritoneal dialysis confirmed a massive left-sided pleural effusion (Figure 1a). The echocardiogram revealed concentric (CAPD); end-stage renal disease (ESRD); hydro-thorax; Tc-99m macroaggregated human albumin left ventricular hypertrophy with adequate global performance , and no pericardial effusion. The abdominal (MAA) peritoneal scintigraphy sonogram showed ...

Woodworkers in the furniture industry are exposed to wood dust in their workplaces. The aim of this study is to investigate the effect of occupational wood dust exposure on the nasal mucociliary transport rates (NMTRs) in woodworkers. Twenty five woodworkers and 30 healthy controls were included in this study. Wood dust concentration in workplaces was measured using the sampling device. (99m) T...

Hepatopulmonary syndrome is defined as the clinical triad of advanced liver disease, arterial deoxygenation and intrapulmonary vascular dilatation. Its pathogenesis is not completely understood. Excessive pulmonary nitric oxide production seems to be one of the factors that contribute to the intrapulmonary vascular dilatation. Other mediators such as endothelin-1 and the heme oxygenase-1/carbon...
