Median survival time was significantly longer for dogs with chronic onset of disease (30 days; range, 0 to

959 days) than for those with acute onset of clinical signs (1.5 days; range, 0 to 120 days).

Conclusions and Clinical Relevance-Results suggested that aortic thrombosis is a rare condition in dogs and accounted for only 0.0005% of hospital admissions during the study period. The clinical signs for dogs with aortic thrombosis differed from those seen in feline patients with aortic thromboembolism. Median survival time was significantly longer for dogs with chronic disease than for dogs with acute disease. Despite treatment, outcomes were typically poor, although protracted periods of survival SHP099 in vivo were achieved in some dogs. (J Am Vet Med Assoc 2012;241:910-915)”
“Although the check details utility of magnetic resonance imaging (MRI) as a universal screening tool in preterm infants has been contested, it is increasingly used to investigate neonatal seizures. The authors evaluated 236 infants <34 weeks’ gestation at birth. seizures were documented according to the clinical standard of care. Infants underwent MRI and head ultrasound during the neonatal period, and a neuroradiologist

and ultrasonologist performed detailed reviews of the images. During the hospital Course, 9 infants (3.8%) had clinical suspicion Of seizures. Magnetic resonance imaging was abnormal in each case. Periventricular hemorrhagic infarct was more common in infants with seizures. Infants with seizures were more likely to have white matter injury, though the difference was not significant. Head ultrasound ACY-738 order failed to detect the extent of brain abnormality in 8 (89%) of the infants. In this large cohort, infants with clinical suspicion of seizures had a high rate of Mill abnormalities that were not as well characterized by head ultrasound. Magnetic resonance imaging may be the study of choice for evaluating preterm

infants with seizures.”
“Left-handed metamaterials (LHMs) with fractal dendritic cells have recently been demonstrated at both microwave and infrared frequencies. Here, we try to utilize Only a single parameter, the fractal dimension. to manipulate the geometries of dendritic structures, and then adjust the resonant behaviors and lossy characteristics of the dendritic LHMs. Both the dendritic LHMs for electromagnetic wave parallel and normal incidences are discussed in this paper. As the fractal dimension increases, the left-handed resonant frequency of the dendritic LHMs decreases, and the lossy characteristics Could be well adjusted. The method proposed in this paper Could be an important guidance for LHMs’ design, especially for the dendritic LHMs operating at optical frequencies (C) 2009 American Institute of Physics [doi: 10.1063/1.
