Context: Dopamine agonists are the treatment of choice for prolactinomas and symptomatic idiopathic hyperprolactinemia. However, the optimal treatment strategy and treatment duration is not clear in all details. Objective: The aim of the study was to assess the effect of dopamine agonist withdrawal in patients with idiopathic hyperprolactinemia and prolactinomas. Data Sources: PubMed, the Cochrane
Rapid development of computer capacity and advances in numerical solution methods for the governing equations of fluid flow and heat transfer have enabled CFD (computational fluid dynamics) methods to gradually become useful tools in research and development, engineering design and analysis of heat transfer equipment. However, turbulence modelling still presents a problem as accurate and reliable
BACKGROUND: In animals, we have previously done successful lung transplantations using organs from non-heart-beating donors. We have also developed an ex-vivo system of assessing the function of such organs before transplantation. The next stage was to try the technique in human beings. Bearing in mind the sensitive ethical issues involved, our first aim was to find out what procedures would be ac
Administration of oligodeoxynucleotides (ODNs) containing CpG motifs generates a rapid and potent response of CC-chemokines, known as ligands of the HIV-1 co-receptor CCR5, in the murine female genital tract. The present study explored the potential HIV inhibitory activities of different human CpG prototypes either alone or conjugated to the non-toxic subunit of cholera toxin (CTB). Results showed
Sera from 79 patients with acute self-limiting hepatitis, 17 patients with acute hepatitis B evolving into chronic HBsAg carriership, and 43 chronic HBsAg carriers without a history of acute hepatitis were analyzed for presence of hepatitis B virus (HBV)-DNA by a molecular hybridization technique. In acute self-limiting hepatitis, HBV-DNA was cleared within a few weeks after the onset of clinical
Meningitis caused by Escherichia coli K1 is a serious illness in neonates with neurological sequelae in up to 50% of survivors. A high degree of bacteremia is required for E. coli K1 to cross the blood-brain barrier, which suggests that the bacterium must evade the host defence mechanisms and survive in the bloodstream. We previously showed that outer membrane protein A (OmpA) of E. coli binds C4b
Background: A DGGE-based assay for hepatitis B virus (HBV) drug-resistance monitoring was designed and checked for feasibility. It detects mutations within the YMDD motif related to lamivudine resistance. Material/Methods: The YMDD motif of HBV polymerase was amplified by the set of primers designed in this study. DGGE analysis of the amplicons was performed on 9% polyacrylamide gels containing a
The adenosine analog 5,6-dichloro-1-beta-D-ribofuranosylbenzimidazole (DRB) was found to increase the production of hepatitis A (HAV) antigen in two monkey kidney cell lines (Frhk-4 and Vero cells). DRB, a known inhibitor of the synthesis of messenger RNA, caused moderate changes in cell morphology. However, Frhk-4 cells could be maintained for several weeks at 80 microM of DRB, the concentration
Cellular metabolism of glucose is required for stimulation of insulin secretion from pancreatic beta cells, but the precise metabolic coupling factors involved in this process are not known. In an effort to better understand mechanisms of fuel-mediated insulin secretion, we have adapted 13C NMR and isotopomer methods to measure influx of metabolic fuels into the tricarboxylic acid (TCA) cycle in i
We review studies of the implementation of human papillomavirus (HPV) vaccination programmes in developed and developing countries. The review spans the period from establishment of long-term vaccine efficacy follow-up studies, operational research on issues of vaccine preparedness, and relevant predictive modelling studies during the pre-licensure phase to plans of phase IV effectiveness trials,
The scientific community has gratefully embraced floating-point arithmetic to escape the close attention for accuracy and precision required in fixed-point computational styles. Though its deficiencies are well known, the role of the floating-point system as standard has kept other number representation systems from coming into practice. The paper discusses the relation between fixed and floating-
Background Semaglutide is a novel glucagon-like peptide-1 (GLP-1) analogue, suitable for once-weekly subcutaneous administration, in development for treatment of type 2 diabetes. We assessed the efficacy and safety of semaglutide versus the dipeptidyl peptidase-4 (DPP-4) inhibitor sitagliptin in patients with type 2 diabetes inadequately controlled on metformin, thiazolidinediones, or both. Method
Transboundary environmental problems pose a specific challenge to the international legal system, as they often demand instruments providing for collective and far-reaching measures on a global scale. Such measures may interfere with other areas of international law, including trade law, human rights law and international humanitarian law (IHL), which may permit conflicting behaviour. The interfer
Design of discontinuity regions in reinforced concrete is today often performed with Strut and Tie Method (STM) or linear finite element analyses (LFEA). However, it is questionable to what extent these design methods are appropriate with regard to resistance, ductility, serviceability and economic reinforcement arrangement. In design with STM a simple equilibrium model based on plasticity theory
Secretagogin is a newly identified calcium-binding protein selectively expressed in neuroendocrine tissue and pancreatic beta-cells. The function of secretagogin is unknown, but it has been suggested in beta-cells to influence calcium-influx, insulin secretion and proliferation, and has been observed downregulated in diabetes-prone BB rat islets exposed to cytokines. In the present study, we ident
We have previously shown how it is possible to lower accident risk levels while at the same time increasing traffic flows with the aid of vehicular ad-hoc networks. In this paper, we extend the online traffic accident risk mitigation sys- tem to include link choice. We develop an algorithm that allows vehicles to choose road links that provide the current maximal utility, based on information rece
NKT cells m the mouse recognize antigen in the context of the MHC class I-like molecule CD1d and play an important role in peripheral tolerance and protection against autoimmune and other diseases NKT cells are usually activated by CD1d-presented lipid antigens However, peptide recognition m the context of CD 1 has also been documented, although no self-peptide ligands have been reported to date H
