It is widely accepted that interleukin-1beta (IL-1beta), a cytokine produced not only by immune cells but also by glial cells and certain neurons influences brain functions during infectious and inflammatory processes. It is still unclear, however, whether IL-1 production is triggered under nonpathological conditions during activation of a discrete neuronal(More)
BACKGROUND Germline mutations in the BRCA1 and BRCA2 genes highly predispose to breast and ovarian cancer. In families with BRCA1 or BRCA2 mutations, identification of mutation carriers is clinically relevant in view of the options for surveillance and prevention. METHODS We assessed presymptomatic DNA testing and prophylactic surgery in 53 consecutive(More)
PURPOSE Breast cancer in BRCA1 and BRCA2 gene-mutation carriers may differ from so-called sporadic breast cancer in clinical features and behavior. These potential differences may be of importance for the prevention, screening, and, ultimately, treatment of breast cancer in women with such germline mutations. Thus far, there have been very few studies on(More)
The PILATUS 1M detector is a hybrid pixel array detector with over one million pixels that operate in single photon counting mode. The detector, designed for macromolecular crystallography, is the largest pixel array detector currently in use at a synchrotron. It is a modular system consisting of 18 multichip modules covering an area of 21 cm x 24 cm. The(More)
OBJECTIVE To quantify the 3-dimensional translation and rotation components of head motion during computed tomography and to analyze the influence of such motion on perceptible artifacts and distortion of volume image data sets. METHODS Using high-precision optoelectronic motion-capture technology, changes in patient head position during axial CT scanning(More)
OBJECTIVES Peutz-Jeghers syndrome (PJS) is an autosomal dominant inherited disorder associated with increased cancer risk. Surveillance and patient management are, however, hampered by a wide range in cancer risk estimates. We therefore performed a systematic review to assess cancer risks in PJS patients and used these data to develop a surveillance(More)
BACKGROUND Hereditary breast cancer has been associated with mutations in the BRCA1 and BRCA2 genes and has a natural history different from sporadic breast cancer. We investigated disease-free and overall survival for patients with a proven BRCA1 alteration. METHODS We estimated disease-free and overall survival for 49 Dutch patients from 19 consecutive(More)
OBJECTIVES Approximately 10-15% of all pancreatic cancers (PCs) may be hereditary in origin. We investigated the use of endoscopic ultrasonography (EUS) for the screening of individuals at high risk for developing PC. In this paper the results of first-time screening with EUS are presented. METHODS Those eligible for screening in this study were(More)
Hereditary non-polyposis colorectal cancer (HNPCC) is the most common genetic susceptibility syndrome for colorectal cancer. HNPCC is most frequently caused by germline mutations in the DNA mismatch repair (MMR) genes MSH2 and MLH1. Recently, mutations in another MMR gene, MSH6 (also known as GTBP), have also been shown to result in HNPCC. Preliminary data(More)
Mutation analysis for autosomal dominant hereditary breast/ovarian cancer genes (BRCA1/BRCA2) became an important technique for women at risk of carrying these mutations. Healthy female mutation carriers have a high lifetime risk for breast and/or ovarian cancer and may opt for frequent breast and ovary surveillance or prophylactic surgery (mastectomy(More)
