The CCSD(T) method has been used to compute a highly accurate quartic force field and fundamental frequencies for all 16O and 18O isotopomers of the ozonide anion. The CCSD and CASPT2 methods have also been used to verify the reliability of the CCSD(T) fundamental frequencies. The computed fundamental frequencies are in agreement with gas-phase experiments, but disagree with matrix isolation exper

The influence of external vibrations on the frictional force has been studied, using different frequencies, amplitudes, loads and materials. The results show that it is possible to affect the frictional force between two surfaces in contact through vibration. The frictional force can be weakened chiefly through a separation of the surfaces or strengthened by welding phenomena in the contact surfa

To be of therapeutic relevance, a tumor-associated antigen should be expressed on the surface of neoplastic cells but not, or to a significantly lower extent, on cells of non-transformed nature. The Ku heterodimer (Ku70/80) is involved in DNA double strand break recognition and repair and is ubiquitously expressed in the nucleus of all cells. However, its exclusive nuclear localization has been re

In 8 donor pigs, flush perfusion was performed with a low-potassium-dextran solution. Ring segments were taken from a small intralobar pulmonary artery in the right lung immediately after perfusion and after 24 hours of cold storage for studies in organ baths. Stable vasoconstriction was induced with the thromboxane mimic U-46619, and acetylcholine was used to induce endothelium-dependent relaxati

The alpha 2B adrenergic receptor (A2AB) is a heptahelical G protein-coupled receptor for catecholamines. We compared the almost complete coding region (about 1,175 bp) of the A2AB gene from 48 mammalian species, including eight newly determined sequences, representing all the 18 eutherian and two marsupial orders. Comparison of the encoded proteins reveals that residues thought to be involved in a

Tissue accumulation of leukocytes constitutes a rate-limiting step in endotoxin-induced tissue injury. Chemokines have the capacity to regulate leukocyte trafficking. However, the role of CXC chemokines, i.e., macrophage inflammatory protein-2 (MIP-2) and cytokine-induced neutrophil chemoattractant (KC), in leukocyte recruitment, microvascular perfusion failure, cellular injury, and apoptosis in t

Antibody binding sites provide an adaptable surface capable of interacting with essentially any molecular target. Using CDR shuffling, residues important for the assembly of mucin-1 specific paratopes were defined by random recombination of the complementarity determining regions derived from a set of mucin-1 specific clones, previously selected from an antibody fragment library. It was found that

Perlecan is a heparansulfate proteoglycan found in basement membranes, cartilage, and several mesenchymal tissues that form during development, tumour growth, and tissue repair. Loss-of-function mutations in the perlecan gene in mice are associated with embryonic lethality caused primarily by cardiac abnormalities probably due to hemopericards. The aim of the present study was to investigate the m

Background and Purpose: To explore the experiences of patients undergoing basic body awareness therapy in psychiatric physiotherapy. In addition, the therapeutic relationship and the concept of the working alliance were examined. Subjects: Two groups of patients participated: patients with schizophrenia (n=6) and general psychiatric outpatients (n=5). Method: A qualitative technique, video taping

Skeletal muscle trauma and myocardial infarction both increase the serum values of the creatine kinase isoenzyme MB (CK-MB) which may render the diagnosis of perioperative myocardial infarction in major orthopaedic surgery more difficult. The significance of postoperative changes in CK-MB was studied in 30 patients subjected to total hip replacement (THR), and the results were compared to CK-MB in

Metal ions are essential cofactors for precursor tRNA (ptRNA) processing by bacterial RNase P. The ribose 2'-OH at nucleotide (nt) –1 of ptRNAs is known to contribute to positioning of catalytic Me2+. To investigate the catalytic process, we used ptRNAs with single 2'-deoxy (2'-H), 2'-amino (2'-N), or 2'-fluoro (2'-F) modifications at the cleavage site (nt –1). 2' modifications had small (2.4–7.7-

Obstructive sleep apnoea (OSA) is a recognised risk factor for hypertension (HT). The current authors investigated confounders of this association in a sex-balanced community-based sample of patients with HT (n=161) from the Skaraborg Hypertension and Diabetes Project (n=1,149) and normotensive controls (n=183) from an age and sex stratified community-based population sample (n=1,109). All partici

We conducted a cross-sectional study of Malay articipants aged 40-80 years (n = 2,932) to examine the associations between polymorphisms at newly identified, lipid-associated loci with blood lipid levels and prevalent cardiovascular disease (CVD) in a Malay population in Asia. A polymorphism adjacent to the TRIB1 locus (rs17321515) was associated with elevated total cholesterol and LDL-cholesterol

Recombinant FVIIa has been developed for treatment of bleedings in hemophilia patients with inhibitors, and has been found to induce hemostasis even during major surgery such as major orthopedic surgery. Recombinant FVIIa is being produced in BHK cell cultures and has been shown to be very similar to plasma-derived FVIIa. The use of rFVIIa in hemophilia treatment is a new concept of treatment and

This paper compares the development of tense morphology and verb-second in different learner populations. Three groups of Swedish pre-school children are investigated longitudinally; ten L1 children, ten L2 children and ten children diagnosed with Specific Language Impairment (SLI). Data was collected twice, with an interval of six months. The results at Time I reveal a significant difference betw

BACKGROUND: There are no previous studies investigating when and where those who die pre-hospitally after an AMI paid their last visit to medical care. Methods and RESULTS: Incidence of AMI, pre-hospital and 28-day case fatality rates were monitored over 13 years of follow-up, in relation to sex-specific quartiles of annual income in all inhabitants aged 40-64 years in Malmö, Sweden. Both incidenc

This study examined the relations between food patterns and five components of the metabolic syndrome in a sample of Swedish men (n = 2,040) and women (n = 2,959) aged 45-68 years who joined the Malmo Diet and Cancer study from November 1991 to February 1994. Baseline examinations included an interview-administered diet history, a self-administered questionnaire, blood pressure and anthropologic m
