Application-specific ICs have been traditionally used to support the high computational and data rate requirements in medical ultrasound systems, particularly in receive beamforming. Utilizing the previously developed efficient front-end algorithms, in this paper, we present a simple programmable computing architecture, consisting of a field-programmable(More)
The quantification of plasma 25-hydroxyvitamin D3 3-sulfate [25(OH)D3S] is expected to be helpful in the assessment of the vitamin D status, especially for infants. In this study, a simple and sensitive method for the quantification of 25(OH)D3S in plasma using liquid chromatography/electrospray ionization-tandem mass spectrometry (LC/ESI-MS/MS) has been(More)
BACKGROUND Guidelines recommend avoiding excessive oxygen during neonatal resuscitation. Recent studies have suggested that oxygen titration can be achieved using a self-inflating bag, but data on the effectiveness of resuscitators used in neonatal ventilation are scarce, The aim of this study was therefore to determine the amount of oxygen delivered using(More)
BACKGROUND Prednisolone (PSL) has been suggested to be useful for the treatment of Kawasaki disease (KD) resistant to i.v. immunoglobulin (IVIG), but much remains to be elucidated regarding its use. METHODS A total of 1087 subjects were involved in a two-study multicenter prospective investigation of the effects of acute phase therapy on IVIG-resistant(More)
BACKGROUND Familial sick sinus syndrome (SSS) is often attributable to mutations in genes encoding the cardiac Na channel SCN5A and pacemaker channel HCN4. We previously found that SSS with SCN5A mutations shows early onset of manifestations and male predominance. Despite recent reports on the complications of atrial fibrillation (AF) and left ventricular(More)
Bronchogenic cysts are commonly found in the mediastinum, but occasionally in lung parenchyma. We report 3 patients with intrapulmonary bronchogenic cysts. A female presented back pain and a large cystic lesion with an air-fluid level on chest X-ray and computed tomography (CT). Another female was asymptomatic. A well-defined round mass with soft tissue(More)
