Exocrine pancreatic function was studied in patients with long-standing insulin-dependent diabetes mellitus using the secretin-pancreozymin test (n = 53), and estimation of immunoreactive trypsin (n = 43) and pancreatic isoamylase (n = 43). The secretin-pancreozymin test was abnormal in 23 patients (43%). The abnormalities found were a decreased output of(More)
2 The Population Council is an international, nonprofit, nongovernmental institution that seeks to improve the wellbeing and reproductive health of current and future generations around the world and to help achieve a humane, equitable, and sustainable balance between people and resources. The Council conducts biomedical, social science, and public health(More)
BACKGROUND Repetitive painful laser stimuli lead to physiological laser-evoked potential (LEP) habituation, measurable by a decrement of the N2/P2 amplitude. The time course of LEP-habituation is reduced in the capsaicin model for peripheral and central sensitization and in patients with migraine and fibromyalgia. In the present investigation, we aimed to(More)
A pilot study was conducted to determine the concentrations of soluble serum E-cadherin in 36 patients with colorectal cancer or a high-grade dysplasia by the use of an ELISA technique. The results were compared with staging characteristics and concentrations of routine serum carcinoembryonic antigen (CEA). Sixteen patients with benign diseases and nine(More)
BACKGROUND Mitogen activated protein kinases (MAPKs) play a central role in the regulation of both cell growth and differentiation. They are involved in signal transduction of oncogenes and growth factors. The role of MAPK in colonic carcinoma is unknown. AIMS To establish whether the expression and activity of p42/44 MAPKs are altered in colorectal(More)
BACKGROUND Recent studies applied laser-evoked potentials (LEP) for the analysis of small nerve fibre function and focused on the detection of stable C-fibre-mediated potentials (C-LEPs); high technical requirements were needed. The diagnostic significance is still controversially discussed. So far, only few studies focused on the susceptibility of C-LEPs(More)
