We evaluated clinical significance of serum alpha-fetoprotein (AFP)-IgM immune complexes, in comparison with free AFP, on the diagnosis of primary hepatocellular carcinoma (HCC). Serum levels of AFP-IgM immune complexes and free AFP were determined by the ELISA method and electrochemiluminescence, respectively, in 103 healthy controls, 74 patients suffering from primary HCC, 27 patients suffering

The evolution of carbon-oxygen-related defects upon isochronal annealing (75-325 degrees C in 25 degrees C steps for 30 min at each temperature) in electron irradiated Si crystals has been studied by means of local vibrational mode (LVM) spectroscopy. A complicated annealing behaviour of the LVMs related to the C4 (ICiOi) defect has been observed. At about 200 degrees C the bands at 940 and 1024 c

Observations of the ultra-sharp-lined HgMn star chi Lupi made with the Goddard High Resolution Spectrograph after the Hubble Space Telescope First Servicing Mission display the effect of COSTAR corrective optics upon the spectral resolution of several observing modes. The resolution is restored to levels expected in the absence of the telescope spherical aberration for all observations made throug

The article consists in a presentation of endovascular surgery for abdominal aortic aneurysm repair in 23 cases. Two cases required conversion to open surgery, but the procedure could be completed in the remaining 21 cases, with a current duration of follow-up of up to 30 months. There was early leakage in one case, and late leakage in five cases. Late conversion has been necessary in three instan

Gadodiamide injection, a new nonionic, MRI contrast medium, was compared with the ionic agent gadolinium (Gd)-DTPA at 0.1 mmol/kg body weight in a double-blind, randomised trial in 60 patients, 30 receiving each substance, with known or suspected lesions of the central nervous system. The patients were closely questioned about adverse events. In the Gadodiamide injection group, four patients repor

The oscillations between glacial and interglacial climate conditions over the past three million years have been characterized by a transfer of immense amounts of water between two of its largest reservoirs on Earth - the ice sheets and the oceans. Since the latest of these oscillations, the Last Glacial Maximum (between about 30,000 and 19,000 years ago), similar to50 million cubic kilometres of

We investigated here the effect of the novel glial cell line-derived neurotrophic factor (GDNF)-family member neurturin (NTN) on transplanted fetal dopamine (DA) neurons. Three groups of rats with complete unilateral 6-hydroxydopamine (6-OHDA) lesions of the nigrostriatal DA system received intrastriatal grafts of embryonic ventral mesencephalic tissue. Following transplantation animals received r

Popular Abstract in Swedish Miljontals fåglar lämnar Sverige varje höst för att övervintra på sydligare breddgrader och återvänder nästkommande vår för att föda upp sina ungar på de enorma mängder insekter som finns här tack vare det tempererade klimatet. Småfåglar genomför sin flytt etappvis genom att flyga ett antal dagar eller nätter i sträck, beroende på om fågeln är en dag- eller nattsträckarSongbird migrants use stopovers between flight bouts to rest and refuel for the upcoming flights. Behaviours affecting where, when and how long to stay at stopover sites will affect how successful the overall migration will be, which has significant consequences for the overall fitness and mortality of the birds. The main purpose of this work was to investigate stopover behaviours in free-flying m

In this work, three different methods were used to determine the phase behavior of alkyl ketene dimer (AKD) in supercritical carbon dioxide (SC-CO2). Rough values for the total solubility of AKD in SC-CO2 were obtained. The solubility ranges from 1 to 14 mg AKD/g CO2 at temperatures from 40 to 80 degrees C and pressures from 10 to 30 MPa. A significant increase in solubility was observed in the re

We present measurements of Underlying Event observables in pp collisions at root s = 0 : 9 and 7 TeV. The analysis is performed as a function of the highest charged-particle transverse momentum p(T),L-T in the event. Different regions are defined with respect to the azimuthal direction of the leading (highest transverse momentum) track: Toward, Transverse and Away. The Toward and Away regions coll

Consumers are pushing for higher data rates to support more services that are introduced in mobile applications. As an example, a few years ago video-on-demand was only accessed through landlines, but today wireless devices are frequently used to stream video. To support this, more flexible network solutions have merged in 4G, introducing new technical problems to the mobile terminal. New techniqu

Dense camera arrays and offline processing are often used for high-quality 3D and 4D scene capture, but such setups are difficult to use as interactive VR content-creation tools. This thesis investigates whether sparse multi-camera capture can be connected to practical reconstruction and visualization workflows for indoor person-centered scenes. A WebUI-controlled system was designed and implement

A small-scale prototype of the CALIFA calorimeter, which is a subsystem of the R 3 B detector, has been constructed and tested using the 179 MeV proton beam at The Svedberg Laboratory, Uppsala, Sweden. The prototype consists of 15 Csl(Tl) elements with a size of 10 x 30 x 130 mm(3), assembled in a 3 x 5 array. Each crystal was individually tested using gamma-ray sources and the light output unifor

Background: To investigate hand bone loss (HBL) measured by digital X-ray radiogrammetry (DXR) in patients with early rheumatoid arthritis (RA) receiving different treatment regimens, and to evaluate if DXR change rates during the first 12 months correlate with radiological damage after 24 months. Methods: From the total SWEFOT trial population, 159 patients had hand radiographs correctly timed an

There is an urgent need for biomarkers to enable early diagnosis of Alzheimer's disease (AD). It has recently been shown that a variant within the clusterin gene is associated with increased risk of AD and plasma levels of clusterin have been found to be associated with the risk of AD. We, therefore, investigated the diagnostic value of clusterin by quantifying clusterin using an ELISA in plasma f

The ground state properties of Mg-31 indicate a change of nuclear shape at N = 19 with a deformed J(pi) = 1/2(+) intruder state as a ground state, implying that Mg-31 is part of the "island of inversion". The collective properties of excited states were the subject of a Coulomb excitation experiment at REX-ISOLDE, CERN, employing a radioactive Mg-31 beam. De-excitation gamma-rays were detected by

Neutral Pb clusters in the size range from a few tens of atoms up to similar to 100 atoms are studied using synchrotron-based photoelectron spectroscopy. The electronic structure is seen to differ increasingly from that of the solid when the cluster size decreases. The valence band narrows gradually - down to about one fifth of the solid-state band width at the smallest size of few tens of atoms.
