BACKGROUND Digital retinal photography with mydriasis is the preferred modality for diabetes eye screening. The purpose of this study was to evaluate agreement in grading levels between primary and secondary graders and to calculate their sensitivity and specificity for identifying sight-threatening disease in an optometry-based retinopathy screening program. METHODS This was a retrospective ...

Human renal cell carcinoma (RCC) tissue and a cell line derived therefrom. SMKT-R3, showed markedly increased glycolipid sulfotransferase [cerebroside Sulfotransferase iCS'l'i: EC 2.8.2.11] activity and ac cumulated Sulfoglycolipids. Recently, we cloned a human CST cDNA from a SMKT-R3 cDNA library (K. Honke et al., J. Biol. Chem., 272: 48644868, 1997). In this study, we investigated the express...

The rostral nucleus of the solitary tract (rNST) is the first-order taste relay in rats. This study constructed topographical distributions of taste response characteristics (best-stimulus, response magnitude, and taste-tuning) from spike discharges of single neurons in the rNST. The rNST is divided into four subregions along the rostrocaudal (RC) axis, which include r1-r4. We explored single-n...

During hindbrain development, cells become segregated into segmental groups, rhombomeres, by mechanisms that are presently unknown. One contributory factor early in development may be an alternating periodicity in cell surface properties down the neuraxis. This possibility was previously suggested by experiments in which tissue from different segmental levels was apposed in the absence of a bou...

Catalytic aerobic dehydrogenation of organic substrates is going through a Renaissance. Recent advances in this area have led to the discovery of palladium-catalyzed alcohol dehydrogenations and oxidative heteroand carbocyclizations. The development of asymmetric catalytic dehydrogenations is the latest advance in a long line of catalytic asymmetric oxidation reactions. Introduction Asymmetric ...

It is shown that every polyhedron in R3 with m edges can be guarded with at most 27 32m edge guards. The bound improves to 6m + 1 12 if the 1-skeleton of the polyhedron is connected. These are the first non-trivial upper bounds for the edge guard problem for general polyhedra in R3.

Irregular parallel applications, whose data and communication patterns are determined only at run-time, often requires good dynamic resource management (DRM) tailored to the application and/or hardware architecture for e cient execution. To easily provide such DRM system, this paper proposes an object-oriented concurrent re ective language ABCL/R3. In ABCL/R3, various DRM systems including sche...

We improve upon the lower bound for 3-colour hypergraph Ramsey numbers, showing, in the 3-uniform case, that r3(l, l, l) ≥ 2 c log log l . The old bound, due to Erdős and Hajnal, was r3(l, l, l) ≥ 2 2 log2 .
