A method based on hollow fiber liquid phase microextraction (HF-LPME) for analysis of pinic acid and pinonic acid was developed and for the first time successfully applied to ambient aerosol samples. In this method, the aerosol samples were dissolved in 0.05M H(2)SO(4) and the solution was extracted using three-phase HF-LPME where donor phase was 0.1M (NH(4))(2)CO(3). Different parameters like typ
Patients with perihilar cholangiocarcinoma and gallbladder cancer extending into the hilum often present with jaundice and a small future liver remnant (FLR). If resectable, preoperative biliary drainage and portal vein embolization (PVE) are indicated. Classically, these measures have been performed sequentially, separated by 4-6 weeks.
Background: In adults, impaired myocardial repolarization and increased risk of arrhythmia are known consequences of open heart surgery. Little is known, however, about post-operative consequences of cardiopulmonary bypass surgery in children. The aim of this study was to assess ventricular repolarization and coronary perfusion after bypass surgery for atrial septal defect (ASD) repair in children
The small size of the billions of migrating songbirds commuting between temperate breeding sites and the tropics has long prevented the study of the largest part of their annual cycle outside the breeding grounds. Using light-level loggers (geolocators), we recorded the entire annual migratory cycle of the red-backed shrike Lanius collurio, a trans-equatorial Eurasian-African passerine migrant. We
Biomarker identification is of utmost importance for the development of novel diagnostics and therapeutics. Here we make use of a translational database selection strategy, utilizing data from the Human Protein Atlas (HPA) on differentially expressed protein patterns in healthy and breast cancer tissues as a means to filter out potential biomarkers for underlying genetic causatives of the disease.
Previous studies on the evaluation of irritant species from burning cables in a modified prEN 50399 fire test produced FEC/FED values based on ISO TS 13571. However, the ISO standard mentions in its scope that these indices can only be used within e.g. modelling. For this reason Europacable (ECBL) initiated a preliminary case-study to asses the possibility of using modern fire safety engineering t
Polysulfones functionalized with highly phosphonated poly(pentafluorostyrene) side chains of different length were synthesized applying controlled polymerization and modification methods. The graft copolymers' thermal properties were evaluated by differential scanning calorimetry and thermal gravimetrical analyses. The proton conductivity of membrane prepared from the graft copolymer with the shor
The rate coefficients for the chemical reactions (species loss rates, quenching excluded) of the refrigerants CH2F2 (HFC-32), CHClF2 (HFC-22) and CH2FCF3 (HFC-134a), and the solvent CH3CCl3 with O(D-1) are determined relative to CH4 + O(D-1) at 298 K. The resulting rates k(CH2F2 + O(D-1)) = (4.78 +/- 1.03) x 10 (11) cm(3) molecule (1) s (1), k(CHClF2 + O(D-1)) = (8.69 +/- 1.72) x 10 (11) cm(3) mol
Eae5 in rats was originally identified in two F-2 intercrosses, (DA x BN) and (E3 X DA), displaying linkage to CNS inflammation and disease severity in experimental autoimmune encephalomyelitis (EAE), respectively. This region overlaps with an arthritis locus, Pia4, which was also identified in the (E3 X DA) cross. Two congenic strains, BN.DA-Eae5 and BN.DA-Eae5.R1, encompassing the previously des
The development of mature B lymphoid cells involves a highly orchestrated regulation of stage- and lineage-specific genes. In this study, we report an analysis of the human surrogate L chain VpreB promoter. The promoter has an overall homology of 56% to the mouse counterpart and displays a preB cell-restricted activity in transient transfections in cell lines. The promoter harbors three independen
The complete mitochondrial genomes of two reptiles, the common iguana (Iguana iguana) and the caiman (Caiman crocodylus), were sequenced in order to investigate phylogenetic questions of tetrapod evolution. The addition of the two species allows analysis of reptilian relationships using data sets other than those including only fast-evolving species. The crocodilian mitochondrial genomes seem to h
Pressurized liquid extractions were performed on eight sediments in order to investigate if a modified US EPA method (100 degrees C, 100 bar, n-heptane/acetone (1:1), 2 x 5 min) provided exhaustive extractions of polychlorinated biphenyls (PCBs) from sediment, and to study if the extractability of PCBs from the different sediments was affected by characteristics of the sediment. The recovery from
Cocaine- and amphetamine-regulated transcript-derived peptides (CARTp) and corticotropin-releasing factor (CRF) alter feeding and gastrointestinal function after central administration, and the gastric inhibitory effects are mediated through CRF. We hypothesized that dorsal hindbrain effects of CARTp on gastric emptying are mediated by the vagus nerve and that the dorsal vagal complex (DVC) is a s
Coupled cluster methods are compared to multiconfigurational second-order perturbation theory in a study of the high spin d(x)s(2) -> d(x+1)s(1) excitations in first, second, and third row transition metals. Large basis sets of the atomic natural orbital type are used. Scalar relativistic effects are included using the Douglas-Kroll-Hess Hamiltonian. The effect of spin-orbit coupling is demonstrat
Neutral B meson oscillations in the B-s(0) - <(B-s(0))over bar>, and B-d(0) - <(B-d(0))over bar> systems were studied using a sample of about 4.0 million hadronic Z decays recorded by the DELPHI detector between 1992 and 2000. Events with a high transverse momentum lepton were removed and a sample of 770 k events with an inclusively reconstructed vertex was selected. The mass difference between th
Biotinylated negatively charged liposomes as well as membranes were affinity partitioned in an aqueous poly(ethylene glycol)-dextran two-phase system using NeutrAvidin conjugated to dextran as affinity ligand. Both liposomes and membranes redistributed from top to bottom phase upon addition of NeutrAvidin-dextran. The presence of 35-60 mM Li2SO4 was necessary both to force the components into the
Syftet är att studera och analysera processer vars mål är att förändra vardagen för två marginaliserade grupper, så att de i större utsträckning blir delaktiga i samhället. De två undersökta grupperna är manliga unga narkomaner och äldre utvecklingsstörda. Avhandlingen består av tre geografiska perspektiv: 1) det tidsgeografiska synsättet, 2) känslan för platsen och 3) socialgeografiska teorier omThe aim is to study and analyse processes intended to change the daily lives of two marginalised groups and enable them to participate to a greater extent in the community. The two marginalised groups are young male drug addicts and older intellectually disabled. The thesis is permeated by three geographic perspectives: 1) the time-geographic approach, 2) sense of place and 3) social-geographic th
We report on experimental absolute oscillator strengths for 18 UV lines of Ru II, obtained by combining laser-induced fluorescence measurements of radiative lifetimes and branching fractions from line intensities in a calibrated Fourier-transform spectrum. HST/GHRS observations of the spectrum of the sharp-lined B star chi Lupi contain six of these lines, for which ''astrophysical'' relative f-val
