The sodium (Na+)/iodide (I-)-symporter (NIS) is abundantly expressed and accumulates iodide in thyroid follicular cells. The NIS is also found in extrathyroidal tissues, particularly gastric mucosa. Controversies exist on the localization of extrathyroidal NIS. We have studied the presence of both NIS peptide and NIS messenger RNA (mRNA) in the digestive tract and thyroid from different mammals. T

This study investigated behaviour of male European pine sawflies, Neodiprion sertifer Geoffr. (Hym., Diprionidae), that were released downwind from pheromone traps. Releases were done at three distances; either at 5 m from one trap, or at 50 m or 200 m from five traps, placed in a line perpendicular to the current wind direction. As a control, males were released identically but without any pherom

Gases leaking from a polyethene plant and a cracker plant were visualized with the gas-correlation imaging technique. Ethene escaping from flares due to incomplete or erratic combustion was monitored. A leakage at a high-pressure reactor tank could be found and visualized by scanning the camera system over the industrial site. The image processing methods rely on the information from three simulta

It has been shown that the generally accepted assumption that hydrophobic molecules and ions repel each other in polar solvents is only valid for moderately polar solvents. When the dipole moment of the medium molecules is increased, then ions and hydrophobic particles start to attract each other. For particles with the size and dipole moment of a water molecule one can expect that the effective p

OPENLAND3 belongs to a suite of computer programs included in the POLLSCAPE simulation model. These programs make it possible to calculate estimates of pollen loadings in lake basins or bogs using vegetation data. OPENLAND3, written in Visual Basic 6, is designed to produce appropriate vegetation data files from vegetation maps stored in a Geographical Information System. It calculates percentage

In this report we consider the linear quadratic control problem under the restriction that the control variable is constant over the sampling intervals. Algorithms and flow chart for numerical solution are presented. The program can be used to design optimal control systems and to compute optimal filters and predictors for implementation on process control computers.

Wilms tumor (WT) is characterized by a nonrandom pattern of chromosome aberrations, but the clinical significance of different cytogenetic patterns is unknown. The present study describes the cytogenetic findings and the clinical course in a cohort of 39 children with WT. Samples for short-term culturing and cytogenetic analysis were obtained during a 15-year period. Clonal chromosome aberrations

The objective of this research that has taken me halfway to my PhD degree was to understand how HCCI combustion behaves in a small volume at high rotational speed. The investigation has been carried out using a modified model airplane engine. The whole study can be divided into two main parts; in the first, the nature of the glow plug combustion was investigated through experiments on a metal engi

Alanine aminotransferase (ALT) levels decline during pregnancy in women chronically infected with hepatitis C virus (HCV). In order to understand further the underlying mechanisms, we prospectively followed 10 chronically infected women before, during and after pregnancy. ALT levels were analysed together with quantification of serum HCV-RNA using the branched DNA technology. As anticipated, the A

We report on our findings of the bright, pulsating, helium atmospherewhite dwarf GD 358, based on time-resolved optical spectrophotometry. Weidentify 5 real pulsation modes and at least 6 combination modes atfrequencies consistent with those found in previous observations. Themeasured Doppler shifts from our spectra show variations with amplitudesof up to 5.5 km s-1 at the frequencies inferred fro

Hemicellulolytic obligate anaerobes capable of converting a range of agricultural substrates and monomeric sugars of hemicellulose to solvents and acids were isolated from cow rumen fluid. The strains were identified as 5 strains of C. beijerinckii (3 different genotypes), 3 strains of C. acetobutylicum (2 different genotypes), 1 strain of C. butyricum and 3 strains of C. bifermentans (2 different

Complement is a cascade-like system that is part of the innate immune defence. It is an explosive system, potentially harmful also for the host cells, and needs to be strictly regulated. An important down-regulator of complement is C4b-binding protein (C4BP). C4BP contains two different types of subunits, seven identical a-chains and one unique P-chain. The alpha-chains bind to C4b, C4BP's target

Extracellular nucleotides such as ATP and UTP are released by activation of platelets and ischemic tissue injury. The aim of the present study was to investigate whether ATP and UTP can induce acute tPA release from the vascular endothelium in vivo. Nine healthy subjects were studied in a perfused-forearm model during stepwise intraarterial infusions of ATP and UTP (10-200 nmol/min), and UTP durin
