The effect of WR 149024, an alpha-receptor antagonist, on survival following hemorrhage with no volume replacement therapy, was investigated. WR 149024 (either 5.0 or 50.0 mg/kg) was administered intraperitoneally (i.p.) to conscious rats during exsanguination. Both WR 149024 treatments caused a significant decrease in survival (P less than 0.021), compared with water-injected controls.

123I-metaiodobenzylguanidine (123I-MIBG) is useful for assessment of the severity and prognosis of patients with chronic heart failure (CHF). To examine 123I-MIBG kinetics in the early phase soon after tracer injection, we performed dynamic single photon emission computed tomography (SPECT) in 76 patients with CHF and 17 control subjects. The consecutive 15 images of 2 min-dynamic SPECT were ac...

The paper discusses the problem of ensuring the QoS performance in wavelength-routed optical burst-switched (WR-OBS) networks under single link failures. The provision of IP services run over high-speed optical backbones should be resilient to faults in the network, hence the importance of WR-OBS survivabihty investigation. A failure-compensating scheduling residing in the WR-OBS control node, ...

In the colliding wind region of early-type binaries, electrons can be accelerated up to relativistic energies displaying power-law spectra, as demonstrated by the detection of non-thermal radio emission from several WR+OB systems. The particle acceleration region, located between the stars, is exposed to strong photon fields in such a way that inverse Compton cooling of the electrons could resu...

The present study examines clinicopathologic findings and their association with the Epstein-Barr virus (EBV) in Waldeyer's ring lymphomas (WRLs) from Indonesia (91 cases), P.R. China (31 cases), Korea (101 cases) and Japan (61 cases). Waldeyer's ring (WR) was categorized into upper and lower parts comprising the pharyngeal and tubal tonsils (upper WR) or palatine and lingual tonsils (lower WR)...

We report the discovery of fifteen previously unknown Wolf-Rayet (WR) stars found as part of an infrared broad-band study of candidate WR stars in the Galaxy. We have derived an empirically-based selection algorithm which has selected ∼5000 WR candidate stars located within the Galactic Plane drawn from the GLIMPSE (midinfrared) and 2MASS (near-infrared) catalogues. Spectroscopic follow-up of 1...

S-2-(3-Aminopropylamino)ethylphosphorothioic acid (WR-2721) was investigated for its protective effect against radiation-produced damage of jejunum, testis, lung, hair follicles, and a fibrosarcoma of C3Hf/Kam mice. Most of these tissues were radioprotected, and the degree of radioprotection depended on the dose of WR-2721 and the time interval between administration of WR-2721 and radiation tr...

We say a constant of physics C is fine-tuned for life if the width, Wr, of the range of values of the constant that permit, or are optimal for, the existence of intelligent life is small compared to the width, WR, of some properly chosen comparison range R: that is, if Wr/WR << 1. 1 [Wr could also stand for the sum of the widths of the intelligent-life-permitting regions.] The range r of intell...
