BACKGROUND AND OBJECTIVES We evaluated if mRNA expression of survivin, an inhibitor of apoptosis, can be used to detect circulating tumor cells in peripheral blood of patients with various gastrointestinal cancers and if they decrease following complete surgical resection. METHODS Blood samples from 40 gastrointestinal cancer patients were analyzed prior(More)
AIMS With increasing socioeconomic disparity in cardiovascular risk factors, there is a need to assess the role of socioeconomic factors in chronic heart failure (CHF) and to what extent this is caused by modifiable risk factors. METHODS AND RESULTS In a prospective cohort of 18 616 men and women without known myocardial infarction or CHF examined in(More)
BACKGROUND We tested the effects of exercise intensity, sampling intervals, degree of coronary artery stenosis, and demographic factors on circulating N-terminal pro B-Type natriuretic peptide (NT-pro-BNP) and cardiac Troponin T (cTnT) in subjects suspected of coronary artery disease (CAD). MATERIALS AND METHODS A total of 242 subjects referred for(More)
AIMS Patients admitted with chest pain are a diagnostic challenge because the majority does not have coronary artery disease (CAD). Assessment of CAD with coronary computed tomography angiography (CCTA) is safe, cost-effective, and accurate, albeit with a modest specificity. Stress myocardial computed tomography perfusion (CTP) has been shown to increase(More)
Investigations on 147 homosexual men in Berlin-West (17-57 years old, kappa = 32 years) revealed the presence of lymphadenopathy in 90 cases (61.2%). In addition, the Th/Ts-ratio was significantly reduced in the entire homosexual group compared to a control group of heterosexual men (n = 13) of comparable age [2P(z) = 0.0001; Mann-Whitney-U-test]. In(More)
Investigations on 147 young homosexual men living in Berlin (West) revealed lymphadenopathy in 61.2% (90 pat.). This finding was prominent in 43.4% of all cases. Evaluation of total T-, T-helper und T-suppressor lymphocytes by means of immunofluorescence with monoclonal antibodies showed an unchanged total number of T-lymphocytes; in contrast, the T-helper(More)
BACKGROUND Multislice computed tomography (MSCT) is a non-invasive, less expensive, low-radiation alternative to coronary angiography (CAG) prior to valvular heart surgery. MSCT has a high negative predictive value for coronary artery disease (CAD) but previous studies of patients with valvular disease have shown that MSCT, as the primary evaluation(More)
