Lidar (light detection and ranging) is a laser based tool for remote measurement of several atmospheric species of importance. We consider the analysis of a field, consisting of several consecutive measurements, in which the concentrations are proportional to the derivatives in the directions of the light paths. Inference is based on local polynomial kernel regression, both for estimation of the d
AIM: To investigate the expression of gastrin-releasing peptide (GRP) and GRP-receptor mRNA in non-tumor tissues of the human esophagus, gastrointestinal tract, pancreas and gallbladder using molecular biology techniques. METHODS: Poly A(+) mRNA was isolated from total RNA extracts using an automated nucleic acid extractor and, subsequently, converted into single-stranded cDNA (ss-cDNA). PCR ampli
Nuclear chirality is a novel manifestation of spontaneous symmetry breaking resulting from an orthogonal coupling of angular momentum vectors. In triaxial nuclei with an odd number of protons and neutrons three perpendicular angular momenta provided by the valence particles and collective rotation can form two systems of opposite handedness. The electromagnetic properties of the resulting doublet
Mammalian leukotriene A4 (LTA4) hydrolase is a bifunctional zinc metalloenzyme possessing an Arg/Ala aminopeptidase and an epoxide hydrolase activity, which converts LTA4 into the chemoattractant LTB4. We have previously cloned an LTA4 hydrolase from Saccharomyces cerevisiae with a primitive epoxide hydrolase activity and a Leu aminopeptidase activity, which is stimulated by LTA4. Here we used a m
Interaction between cultural development and the natural environment is generally accepted. Holocene climate change is described as one of the main environmental factors behind a step-wise development of the cultural landscape in Northwest Europe. Seven periods of human impact changes-5900, 5500, 4500, 3800, 3000-2800, 1500 and 1100 cal. BP-are defined and compared with reconstructed climatic scen
When radio-iodine was first used in the treatment of metastasized thyroid carcinoma in 1943, its success in terms of tumour response, quality of life improvement and survival was considered a 'miracle', as in those days metastatic cancer was generally fatal. Inspired by this, many efforts have been made to apply radioisotope therapy to other tumours. Radionuclide therapy uses radioactive isotopes
Delayed hydride cracking (DHC) velocity was determined at 203,227,250 and 283 degrees C using 17 mm width curved compact toughness specimens machined from an unirradiated Zr-2.5 wt.% Nb pressure tube spool, gaseously charged with 60 ppm of hydrogen by weight. Single CT specimen was used to determine DHC velocity at a constant temperature for a range of stress intensity factor (K-1) obtained by loa
Sixty-five patients who were primary or secondary refractory to melphalan/prednisone or other type of chemotherapy, or relapsed within 6 months after high dose chemotherapy with stem cell support, were given thalidomide at a dose of 200 mg/d escalating to 800 mg. The patients were followed for a median of 2 years and 22 weeks. Response was evaluated according to M-protein reduction combined with i
Tailored supercritical carbon dioxide (scCO(2)) extraction of alkyhesorcinols (ARs) from rye bran resulting in pre-purification of ARs already during extraction process. The pre-purification was achieved by splitting the extraction process in 2 steps.. In both steps, the CO2 pressure was set at 25 MPa with a flow rate of 10 g/min. The first step was carried out at 70 degrees C. 0.06% of ethanolic
We present a case of splenic artery aneurysm (SAA) treated with stent-grafts. This new method offers the benefit of preserving the blood flow through the splenic artery. This in turn allows for subsequent sequential embolization of the spleen when indicated, as in our patient with hypersplenism. This is the first reported case of stent-graft repair of SAA.
An overview of chiral perturbation theory calculations in the mesonic sector at the two loop level is given. Discussed in some detail are the partially quenched case relevant for lattice QCD, the general fitting procedures and ππ, πK scattering as well as the determination of Vus and K13 decays
PURPOSE: To investigate the influence of smoking on the development of radiation-induced pneumonitis in patients treated for breast and oesophagus cancer. MATERIALS AND METHODS: This is a retrospective study on 405 females diagnosed with primary unilateral breast cancer stages 1 and 2 and 201 oesophagus carcinoma patients. The possibilities in Sweden to obtain detailed information from different m
Phosphine derivatives of alkylidyne tricobalt carbonyl clusters have been tested as catalysts/catalyst precursors in intermolecular and (asymmetric) intramolecular Pauson-Khand reactions. A number of new phosphine derivatives of the tricobalt alkylidyne clusters [Co(3)(mu(3)-CR)(CO)(9)] (R = H, CO(2)Et) were prepared and characterised. The clusters [Co(3)(mu(3)-CR)(CO)(9-x)(PR'(3))(x)] (PR'(3) = a
