Drs. Whisenant and Venook have provided us with a summary of the role of hepatic arterial infusion (HAI) chemotherapy for patients with metastatic colorectal cancer. In their abstract they state that there is confusion about whether HAI for unresectable liver metastases is useful, because European studies have been negative; they go on to say that the work in adjuvant therapy has mixed results....

While many materials are sensitive to light and can be used for making photographs, the present art of photography is based upon one specific process : The light-sensitive material is silver bromide in the form of extremely small crystals held in a layer of gelatin. These crystals are very sensitive to light when the reaction to light is made manifest by the process of development, that is, by ...

We investigated the effect of a candidate artificial blood substitute, Fluosol-DA (FDA), on human neutrophil function in a serum-free medium. In a 50% (vol/vol) mixture with polymorphonuclear cells (PMN), FDA had no effect on PMN viability, phagocytosis, superoxide anion generation, degranulation, or bactericidal activity. In striking contrast, the random migration and chemotaxis of PMN to both...

Blood transfusion centers are under considerable pressure to produce platelet concentrates with a shelf life limit of 3 to 5 days. Many approaches have been investigated experimentally to produce new hemostatically active platelet products that are capable of long term storage. In this article infusible platelet membrane will be explained as a platelet substitute versus conventional liquid-stor...

The interactions between water and n-perfluoroalkanes or substituted alpha-(omega-)fluoroalkanes used in blood substitute formulations were investigated experimentally and using ab initio calculations. The solubility of water in C(6)-C(9) perfluoroalkanes and five C(8) analogues of substituted fluoroalkanes was measured in the temperature range between 288 and 318 K at atmospheric pressure, usi...

Synthetic blood substitutes are substances produced to fulfill functions of biological blood and serve as it’s replacers in diverse medical procedures. Their main function is to restore blood volume and deliver oxygen to tissues. Colloid solutions currently in use lack the ability to bind oxygen and are applied as blood serum equivalents only. Two classes of oxygen-carrying agents are being dev...

This thesis uses an unsensitized emulsion and two chemically sensitized emulsions to investigate the effect of oxygen and water vapor on latent-image formation and stability. At exposure times that cause little or no low-intensity reciprocity failure, vacuum treatment of an emulsion can result in photographic speeds significantly lower than those found in a humidified environment. This is presu...

Background Results of blood test are essential and often guiding for the diagnostic work. In emergency departments (EDs) a competent and rapid treatment therefore requires an efficient process for ordering blood tests, informing clinicians that samples have been taken, for communicating test results, and for physicians acknowledging having assessed results. The ED in Slagelse Sygehus has implem...

Urine discoloration occurs in the intensive care unit (ICU) due to many causes such as medications, metabolic disorders, and infections. Propofol is advocated as one of the first line sedatives in the ICU, but it is not well known to the intensivists that propofol can induce urine color change. We experienced two cases of green urine after propofol infusion. Propofol should be warranted as the ...
