Bicuspid aortic valves (BAVs) are associated with ascending aortic aneurysms. We studied BAV patients before and after aortic valve replacement (AVR) to determine the risk and predictors of aortic root dilatation after surgery. BAV patients (n=60) with an aortic root <or=45 mm who underwent AVR were followed by echocardiography (6.2+/-2 years) and aortic(More)
A study was undertaken in order to evaluate and compare ivermectin's (IVM) plasma disposition kinetic parameters after oral or intramuscular (IM) administration in horses. Ten clinically healthy adult horses, weighing 380-496 kg body weight (BW), were allocated to two experimental groups of five horses. Group I, was treated with an oral paste formulation of(More)
BACKGROUND Calcification and dysfunction of aortic and mitral valves are frequently found in chronic dialysis patients, but their influence on the development of left ventricular hypertrophy (LVH) is not well defined. METHODS Conventional echocardiography and Doppler measurement of trans-aortic flow velocity were performed in 135 chronic haemodialysis(More)
A study was done to compare plasma disposition kinetics and the fecal elimination profile of doramectin (DRM) after oral or intramuscular (IM) administration in horses. Ten clinically healthy horses, 328-502 kg body weight (bw), were assigned to 2 experimental groups of 5 horses each. Group 1 was treated with an oral dose of 0.2 mg DRM/kg bw, while Group 2(More)
PURPOSE In September 1984, the Pediatric Oncology Group began accrual to a Phase I/II study designed to assess the efficacy and toxicity of sequentially escalated doses of hyperfractionated (twice daily) radiotherapy in children with poor-prognosis brain stem tumors. Pediatric Oncology Group Study #8495 closed in June 1990 with a total of 136 patients on(More)
Nine of 168 patients (5.3%) with carcinoma of the esophagus had primary tumors in the cervical esophagus. The principal symptoms and signs of carcinoma of the cervical esophagus were dysphagia, hoarseness, neck mass, and weight loss. The esophagogram was a very reliable study, revealing the abnormality in all nine patients. The true extent of the disease(More)
A study was undertaken in order to compare plasma disposition kinetic parameters of doramectin (DRM) and ivermectin (IVM) in horses after oral administration. Ten crossbreed adult horses, clinically healthy, weighing 380-470 kg body weight (bw) were selected for study. Faecal examinations were performed to determine faecal parasite egg counts. Horses were(More)
To determine the sensitivity, specificity, and predictive values of the sonographic analysis of liver surface irregularities for the diagnosis of cirrhosis, the authors conducted a prospective and blinded study in 70 subjects with abnormal liver function tests. All patients included underwent liver biopsy within 15 days of the sonographic study.(More)
