The radiative lifetimes in the s and d Rydberg sequences of neutral boron were investigated by combining the methods of laser-pulse compression and frequency-up conversion. The multiconfiguration Hartree-Fock (MCHF) method was used to calculate the lifetimes. Rydberg sequences in boron showed strong irregularities in energy due to configuration interaction. The results also showed that the energy

Objective: Previous studies suggest that low birth weight is associated with thyroid autoimmunity and hypothyroidism in later life, but the potential effect of preterm birth, independent of fetal growth, is unknown. Our objective was to determine whether preterm birth is independently associated with medically treated hypothyroidism in young adulthood. Design/Participants: National cohort study of

Factor I (FI) is a soluble, 88 kDa glycoprotein present in plasma at a concentration of approximately 35 mg/L. FI inhibits all complement pathways as it degrades activated C4b and C3b when these are bound to a cofactor such as C4b-binding protein or factor H. Here, we describe a method for purification of FI from human plasma, which is based on affinity chromatography followed by anion exchange ch

Time trends in incidence, causes of death, and prognosis of cancer of unknown primary (CUP) could provide important clues for occult primary sites and thus result in effective organ-specific treatment, although such studies are seldom reported. We aimed at examining time trends in percentage and incidence rates, causes of death, and survival of CUP. A total of 50 545 patients with CUP were identif

Right ventricular heart rupture is a devastating complication associated with negative pressure wound therapy (NPWT) following cardiac surgery. The use of a rigid disc has been suggested to offer protection against this lethal complication by preventing the heart from being drawn up towards, and damaged by, the sharp sternum edges. The aim of the present study was to compare the wound fluid evacua

OBJECTIVE: To understand aggrecan degradation in juvenile idiopathic arthritis (JIA), the pattern and abundance of aggrecan fragments in synovial fluid aspirates from JIA patients were analysed and compared with aggrecan fragments in synovial fluids from patients with other arthritides, juvenile knee injury and a knee-healthy reference group. METHODS: The concentration of sulphated glycosamino

Bovine milk is associated with improved health and reduced risk of several diseases, among them cancer. Milk is a complex mixture of known and unknown components. The components and the mechanisms that contribute to the cancer-preventive effects are largely unknown. We set out to find new peptides in milk and identified ubiquitin (Ub) using matrix-assisted laser desorption ionization-time of fligh

A nonintrusive three-dimensional trap for microscopic particles in a Liquid is described. The trap is based on acoustic radiation forces in an ultrasonic confocal standing-wave cavity. Experiments at 11 MHz demonstrate the concept and verify the theoretically calculated forces. Theoretical calculations for higher-frequency systems indicate a significant potential for low-rms-displacement trapping

von Willebrand's disease (VWD) is probably the most common bleeding disorder, with some studies indicating that up to 1% of the population may have the condition. Over recent years interest in VWD has fallen compared to that of haemophilia, partly the result of focus on blood-borne diseases such as HIV and hepatitis. Now the time has come to revisit VWD, and in view of this some 60 international p

We have explored the potential of cell factory-derived bioactive molecules, isolated from conditioned media of primary goat chondrocytes, for the repair of subchondral cartilage defects. Enzyme-linked immunosorbent assay (ELISA) confirms the presence of transforming growth factor-β1 in an isolated protein fraction (12.56 ± 1.15 ng/mg protein fraction). These bioactive molecules were used alone or

PURPOSE: Histologic grade is currently the best predictor of clinical course in chondrosarcoma patients. Grading suffers, however, from extensive interobserver variability and new objective markers are needed. Hence, we have investigated DNA copy numbers in chondrosarcomas with the purpose of identifying markers useful for prognosis and subclassification. EXPERIMENTAL DESIGN: The overall pattern o

Allergic contact dermatitis (ACD) is mediated by T cells that specifically recognize hapten-modified peptides. T cells are known to recognize antigens as short processed peptides bound to major histocompatibility complex (MHC) molecules on the surface of antigen-presenting cells (APC). It has previously been demonstrated that T cells can specifically recognize carbohydrates on the lysine at positi

The salivary protein statherin is known to adsorb selectively onto hydroxyapatite (HA), which constitutes the main mineral of the tooth enamel. This adsorption is believed to be crucial for its function as an inhibitor of primary (spontaneous) and secondary (crystal growth) precipitation of calcium phosphate salts present in saliva. A fragment corresponding to the first 21 N-terminus amino acids o

CD1d-restricted natural killer T (NKT) cells belong to the innate-like lymphocytes which respond rapidly to stress and infectious challenge. We have studied murine CD1d-restricted NKT cells in the early immune response to virulent Salmonella enterica serovar Typhimurium after oral infection. In the liver and spleen, neutrophil and macrophage numbers had increased several-fold by day 5 post-infecti

Progressive multifocal leucoencephalopathy (PML) is a viral infection occurring in immunocompromised patients. The typical magnetic resonance imaging (MRI) findings include supratentorial asymmetric nonenhancing white matter lesions without mass effect. We present a patient with progressive cerebellar and brain stem lesions, emphasizing the fact that the diagnosis of PML should be considered also

In the present study, we used a multilevel approach to investigate the role of maternal country of birth (MCOB) in predicting adolescent use of psychotropic medication in Sweden.

A chiral ligand-exchange phase for capillary electrochromatography based on continu-ous bed technology was developed. The chiral stationary phase is prepared by a one- step in situ copolymerization procedure using methacrylamide, piperazine diacryla- mide, vinylsulfonic acid and N-(2-hydroxy-3-allyloxypropyl)-L-4-hydroxyproline. These chiral continuous beds are inexpensive and easy to prepare. The

The focus of cancer research is on cancer-specific mutations, with most clinical trials involving targeted drugs. Huge numbers of DNA lesions and tumor resistance events, in each of the >10(13) cells of a human individual, form a striking contrast to the low, and also very narrow, cancer incidence window (10(-1)-10(0)). A detailed consideration of these quantitative observations seems to question
