objective : double aortic arch (daa) is a rare congenital malformation. strategies for diagnosis and treatment are different. thoracoscopic treatment of daa is limited to case reports or little case series. we report a description of our diagnostic and therapeutic approach and evaluate outcomes. methods: we reviewed charts of infants with double aortic arch who were hospitalized in our departme...
Comparison of computerized digital and analog radiography for detection of bronchial pattern in dogs
Background: Analog radiography has been replaced with digital radiography for canine diagnostic imaging in many veterinary clinics. There is no data comparing these modalities in a veterinary clinical setting to detect bronchial pattern signs in dogs. Objectives: In this study, computerized digital radiography (CR) and analog radiography were compared for diagnosis of bronchial pattern in dogs....
In order to study Hall effect in pure and CNT doped YBCO polycrystalline samples, we have measured longitudinal and transverse voltages at the different magnetic field (0-9T) in the vortex state. We found a sign reversal for pure sample near 3T and double sign reversal of the Hall coefficient for CNT doped sample near 3 and 5T. It can be deduced that CNT doping caused strong flux pinning and H...
Use of the double ring infiltrometer to measure soil water infiltration in center pivot irrigation systems isn’t an accurate approach because the real conditions of infiltration under center pivot sprinklers is different from what happens in the double ring. In this study the infiltration parameters were evaluated in real conditions of a center pivot system. For this purpose a single ring...
A 12-year-old boy presented to us with subacute onset of progressive quadriparesis and blurring of vision in the right eye. His sensorium was normal. There was hyper-reflexia and spasticity in all four limbs and the plantar reflex was bilaterally extensor. Vision in the right eye was 6/18. The fundus examination was normal. Cerebrospinal fluid revealed normal sugar, normal cells with raised pro...
