A study of the effect of acetamide as an accelerator of the reaction between free bilirubin and diazotized sulfanilic acid (DSA) has led to its use in a method for serum bilirubin which is simple, sensitive, linear over a wide range, and which requires neither excessive dilution nor protein precipitation. The conditions necessary for greatest sensitivity and for linearity have been established ...

We report cerebral digital subtraction angiography (DSA) using Gadolinium in a patient allergic to iodinated contrast media. A 77-year-old woman was admitted to our hospital for surgical resection of a brain tumor. Although a DSA was requested as a preoperative examination, the patient had a history of allergic reaction to non-ionic iodinated contrast medium. Therefore, DSA was performed using ...

The Inter-university Consortium for Political and Social Research (ICPSR), a domain repository with a 50-year track record of archiving social and behavioural science data, applied for—and acquired—the Data Seal of Approval (DSA) in 2010. DSA is a non-intrusive, straightforward approach to assessing organizational, technical, and operational infrastructure, and signifies a basic level of accred...

This paper presents a finite-element dimension splitting algorithm (DSA) for a three-dimensional (3D) elliptic equation in a cubic domain. The main idea of DSA is that a 3D elliptic equation can be transformed into a series of two-dimensional (2D) elliptic equations in the X–Y plane along the Z-direction. The convergence speed of the DSA for a 3D elliptic equation depends mainly on the mesh sca...

Single data replica management strategy can not meet the complexity and diverseness in data grid. This paper proposes a dynamic self-adapting replica management architecture (DSA-RM) driven by software architecture (SA). In DSA-RM, architecture descriptions are shared by the whole grid environment as a system kernel to schedule various replica management components that are adapted to various a...

Intraoperative angiography in cerebrovascular neurosurgery can drive the repositioning or addition of aneurysm clips. Our institution has switched from a strategy of intraoperative digital subtraction angiography (DSA) universally, to a strategy of indocyanine green (ICG) videoangiography with DSA on an as-needed basis. We retrospectively evaluated whether the rates of perioperative stroke, une...

BACKGROUND AND PURPOSE Time-resolved 3D-DSA (4D-DSA) enables viewing vasculature from any desired angle and time frame. We investigated whether these advantages may facilitate treatment planning and the feasibility of using 4D-DSA as a single imaging technique in AVM/dural arteriovenous fistula radiosurgery. MATERIALS AND METHODS Twenty consecutive patients (8 dural arteriovenous fistulas and...

The consolidation of single antigen beads (SAB-panIgG) assay in the detection of preformed anti-human leukocyte antigen (HLA) antibodies has improved transplantation success. However, its high sensitivity has limited the allograft allocation for sensitized patients, increasing their waiting time. A modification of the standard SAB-panIgG assay allows the detection of that subset of antibodies c...

Simple, selective and sensitive high-performance thin layer chromatographic (HPTLC) method has been developed and validated for the simultaneous determination of hydrochlorothiazide (HCZ) in the presence of its impurities (chlorothiazide (CT) and salamide (DSA)), in two quaternary mixtures with benazepril hydrochloride (BZ) or amiloride hydrochloride (AM). The separation was carried out on HPTL...

3D digital subtraction angiography (DSA) allows clinicians to review intracranial aneurysms and other vascular lesions. We report 2 basilar aneurysms that were imaged by both 3D DSA and DynaCT. These 2 techniques produced very different aneurysm appearances. Anterior portions of the aneurysms were invisible on 3D DSA but were revealed by DynaCT. These aneurysms appeared to have been flattened b...
