In this work, we examine the strength of deep learning approaches for pathology detection in chest radiographs. Convolutional neural networks (CNN) deep architecture classification approaches have gained popularity due to their ability to learn mid and high level image representations. We explore the ability of CNN learned from a non-medical dataset to(More)
In a previous study, we found that oral chromium nicotinate overcame sucrose-induced hypertension in spontaneously hypertensive rats (SHR). Accordingly, we examined more chromium compounds to determine if others were more or less effective in regulating blood pressure (BP) of SHR. Since chromium is postulated to be an antioxidant, we also assessed the(More)
In four patients with hypercholesterolemia (type II hyperlipoproteinemia) and xanthomatosis the decay of serum cholesterol specific activity was followed for 53-63 wk after pulse labeling. Specific activity of biopsied xanthoma cholesterol was measured four times in the course of the study. The xanthoma specific activity curve crossed and thereafter(More)
OBJECTIVE To describe the spectrum and frequency of computed tomographic (CT) features in tuboovarian abscess (TOA) in order to increase the utility of computed tomography in diagnosing this condition. STUDY DESIGN Search of our hospital registry found 22 patients diagnosed with TOA who underwent pelvic tomography between the years 1998 and 2001. A(More)
A gradual increase in blood pressure (BP), often attaining hypertensive levels, is common during aging--"age-related hypertension." Therefore, means to prevent or ameliorate this elevated BP safely are important. Although oral B-nicotinamide adenine dinucleotide (NADH), a natural coenzyme, is used principally to treat various neurologic disorders, we wished(More)
We report a case of hemimegalencephaly diagnosed by prenatal MRI with an emphasis on its appearance on diffusion-weighted images. This case shows that in this condition the enlarged hemisphere may show restricted diffusion on prenatal MRI. In our opinion, this finding may result from a combination of increased cellularity and advanced myelination in the(More)
BACKGROUND Primary hepatic sarcoma is a rare tumour with a poor prognosis. METHODS From 1997 to 2002 eight patients had liver resection for primary sarcoma of the liver at our institution. The clinical characteristics, imaging findings, surgical procedures, adjuvant therapy and outcome were retrospectively reviewed. There were two patients each with(More)
Ingestion of sugars (sucrose, fructose, glucose) by various rat strains is associated with perturbations in the glucose/insulin system and higher systolic blood pressure (SBP). The association suggests causality, because alterations in insulin metabolism have been found in essential hypertension and many experimental forms of hypertension. To test the(More)
OBJECTIVE We estimated the accuracy and safety of imaging-guided needle biopsy for the diagnosis of suspected malignant lymphoma in patients with a splenic lesion. CONCLUSION Imaging-guided small-bore cutting-edge needle biopsy of splenic lesions is a safe procedure. In most patients with primary or recurrent lymphoma, the disease subtype can be diagnosed(More)
Behçet disease is a multisystemic and chronic inflammatory disorder of unknown cause that is characterized by recurrent oral and genital ulcerations, ocular manifestations, and additional clinical manifestations in multiple organ systems. Behçet disease involving the chest can manifest as a wide spectrum of abnormalities. Although conventional chest(More)
