BACKGROUND The anti-CD52 monoclonal antibody alemtuzumab reduces disease activity in previously untreated patients with relapsing-remitting multiple sclerosis. We aimed to assess efficacy and safety of alemtuzumab compared with interferon beta 1a in patients who have relapsed despite first-line treatment. METHODS In our 2 year, rater-masked, randomised controlled phase 3 trial, we enrolled ad...
Polyclonal antibodies to Escherichia coli beta-galactosidase, beta-glucuronidase, and glutamate decarboxylase were used in coagglutination tests for identification of these three enzymes in cell lysates. Enzyme capture assays were also developed for the detection of E. coli beta-galactosidase and beta-glucuronidase. The enzymes were released by using a gentle lysis procedure that did not interf...
This paper describes the development of a prototype that takes in an analog National Television System Committee video signal generated by a video camera and data acquired by a microcontroller and display them in real-time on a digital panel. An 8051 microcontroller is used to acquire power dissipation by the display panel, room temperature, and camera zoom level. The paper describes the major ...
For reasons of phantom material reproducibility, the absorbed dose protocols of the American Association of Physicists in Medicine (AAPM) (TG-51) and the International Atomic Energy Agency (IAEA) (TRS-398) have made the use of liquid water as a phantom material for reference dosimetry mandatory. In this work we provide a formal framework for the measurement of absorbed dose to water using ioniz...
This study examined the role of transforming growth factor beta 1 (TGF-beta 1) in monocytic differentiation of hematopoietic cells. TGF-beta 1 and retinoic acid (RA) inhibited HL-60 cell growth in a dose-dependent fashion. Treatment of HL-60 cells with a combination of TGF-beta 1 and a 50% optimal dose of RA (RA + TGF-beta 1) resulted in increased growth suppression compared to the individual t...
