216 Medical Aspects of Biological Warfare

Polymorphisms of the major histocompatibility complex (MHC) have been linked to many diseases, especially autoimmune disorders. Previous studies have shown that genetic variants in MHC class III are associated with breast cancer. To determine if there is an association between MHC class III and breast cancer risk in the Chinese Han population, we carried out a hospital-based case-control study ...

Acquired resistance to the p.o. active lipophilic platinum drug bis-acetato-ammine-dichloro-cyclohexylamine platinum (i.v.) (JM216) was generated in the 41M and CH1 human ovarian carcinoma cell lines, and their resistance mechanisms were compared to parallel cisplatin-resistant (cisR) cell lines. Intracellular platinum accumulation was not reduced in either 41M/JM216R or CH1/JM216R compared to ...

Skeletons are useful shape abstractions and have varied applications in visualization. The complexity of the desired skeletal structure depends on the application. Current techniques for extracting skeletons do not allow control over the complexity. In this paper, we describe an algorithm which uses a thinness parameter to control the density of the skeleton. We present applications from CFD an...

INTRODUCTION The pursuit of bone fixation systems capable of affording appropriate stability for osteosynthesis has gone through several stages from the use of metal wires, plates, and screws to the current stage of bioabsorbable systems. In our Pediatric Neurosurgery Service and Craniofacial Surgery Unit we began employing these systems in June 1997. The object of this paper is to present a re...

Interferometric observations of asteroid (216) Kleopatra were performed in January 2000 using the Fine Guidance Sensors (FGS) aboard HST. The FGS data obtained clearly suggest that (216) Kleopatra is composed of two lobes in contact, in agreement with the radar data (Ostro et al. 2000, Science 288, 836–839), and provide more precise constraints on the absolute size of this peculiar object. c © ...

plants. The geographical and climatological condition of Querétaro city, and having a large industrial corridor are risk factors for development allergic problems. In Mexico there are no prevalence studies on food allergy and therefore the most common food allergens. The objectives of the study are to identify common allergen sensitization and to determine if there is crossreactivity between cy...
