It is shown that, by optimizing the placement of a solute in a solvent droplet or in a periodic simulation cell, the number of solvent molecules can be reduced without affecting the quality of the simulation. Q 1997 by John Wiley & Sons, Inc. J Comput Chem 18: 812]815, 1997

During experiments on the effect of direct electric currents on red cells suspended in saline an unexpected phenomenon was observed. Normal red cells showed agglutination and lysis, but if the red cells had been sensitized by antibodies there was a marked difference in the degree of agglutination and lysis. Samples of red cells which had been treated with " blocking " Rhesus antibody (anti-D an...

External distraction using a rigid external distractor (RED) frame (RED frame II, KLS-Martin, Jacksonville, USA) is frequently used for maxillary distraction and reconstruction.[1-3] Airway management with the RED frame could be a greater risk of failed intubation/extubation. It could significantly interfere with ventilation with a face mask or intubation by direct laryngoscopy. However, anaest...

A 3-month-old male red fox that was in contact with a Persian cat referred to the small animal hospital, Faculty of Veterinary Medicine, University of Tehran with multi-focal circular non-pruritic skin lesions and hair loss mainly on the head and extremities. A complete series of dermatologic tests such as Wood’s light examination, direct microscopic examination, and fungal culture were perform...

N ASSOCIATION between hepatocellular carcinoma and pol cythemia was reported in 1958 by McFadzean, Todd and Tsang’ who found the red cell mass to be increased in 17 of 28 patients investigated. The red cell masses were calculated from the plasma volumes determined by the T-1824 dye method. When radioactive isotopes became available it was decided further to investigate the red cell mass in hepa...

Removal of the white cells and platelets from suspensions of red cells usually produces substantial reduction in the hemolytic activity of venoms. Guinea pig red cells constitute a notable exception and may be lysed by a direct action of venom. White blood cells and platelets appear to contribute to hemolysis by serving as sources of phosphatides for the formation of lysophosphatides. No correl...

We present 8–13 μm spectra of eight red giants in the globular cluster 47Tucanae (NGC104), obtained at the European Southern Observatory 3.6m telescope. These are the first mid-infrared spectra of metal-poor, low-mass stars. The spectrum of at least one of these, namely the extremely red, large-amplitude variable V1, shows direct evidence of circumstellar grains made of amorphous silicate.

Dapsone hydroxylamine (DDS-NOH) is a direct-acting hemolytic agent responsible for dapsone-induced hemolytic anemia in the rat. The hemolytic activity of DDS-NOH is associated with the formation of disulfide-linked hemoglobin adducts on membrane skeletal proteins. We have postulated that this membrane protein "damage" is a consequence of DDS-NOH-induced oxidative stress within the red cell and ...
