BAliBASE is specifically designed to serve as an evaluation resource to address all the problems encountered when aligning complete sequences. The database contains high quality, manually constructed multiple sequence alignments together with detailed annotations. The alignments are all based on three-dimensional structural superpositions, with the(More)
A prospective evaluation for occult pneumothorax was performed in 25 consecutive patients with serious head trauma by combining a limited chest CT examination with the emergency head CT examination. Of 21 pneumothoraces present in 15 patients, 11 (52%) were found only by chest CT and were not identified clinically or by supine chest radiograph. Because of(More)
In a prospective, multicenter study of 164 patients, cerebral magnetic resonance (MR) angiography with multiple overlapping thin slab acquisition was evaluated for image quality and diagnostic accuracy. Of the 164 patients, 87 (53%) underwent either correlative cut-film angiography or surgery. The overall image quality was excellent in 90% of patient(More)
Six cases of sarcoidosis involving the central nervous system are reported with the neuroradiological findings and appearance on computed tomography. Communicating hydrocephalus with sarcoid arachnoiditis is the most common finding, but arteritis and masses have also been reported. Two rare cases of intracerebral masses are included. The radiological(More)
BACKGROUND A well-characterized dog model of the X-linked collagen disease Alport syndrome (XLAS) was used to study the effect of progressive glomerular disease on megalin-mediated endocytosis. In XLAS, altered structure and function of the glomerular basement membrane induces a progressive proteinuric nephropathy. METHODS The investigation was performed(More)
In vivo experiments in dogs demonstrated angiographically that the subarachnoid injection of blood produced cerebral arterial apasm both immediately after the injection of blood and 2 days later. The sublingual adminstration of nifedipine reversed both the acute and the delayed cerebral arterial spasm. In addition, sublingual administration of nifedipine 20(More)
OBJECTIVE Multiple overlapping thin-slab acquisition (MOTSA) is a hybrid time-of-flight MR angiography technique that combines the advantages of two- and three-dimensional methods. A venetian blind-like artifact, resulting from variations in signal intensity at slab boundaries, is a potentially significant disadvantage. The objective of this study was to(More)
The records of 161 German Shepherd Dogs were divided into groups depending on whether there was a radiographic diagnosis of degenerative disk disease (DDD) involving the lumbosacral disk and lumbosacral transitional vertebral segments (TVS) and whether the dogs had cauda equina syndrome (CES). Statistical analysis of the data suggested an association(More)
Comparative genomics is a superior way to identify phylogenetically conserved features like genes or regions involved in gene regulation. The comparison of extended orthologous chromosomal regions should also reveal other characteristic traits essential for chromosome or gene function. In the present study we have sequenced and compared a region of(More)
The normal 99mTc-diethylenetriaminepentaacetic acid (DTPA) renal scintigram curve has 3 distinct phases; an arterial phase followed by progressive uptake and subsequent excretion from the kidney. In dogs with X-linked hereditary nephritis, a distinct flattening of the renal scintigram curve has been observed prior to any decline in glomerular filtration(More)
