The spin-forbidden reaction of Fe(CO)(4)+CO -> Fe(CO)(5) has been investigated with multiconfigurational quantum chemical methods (CASSCF/CASPT2). The structure of the minimum energy crossing point ( MECP) between the singlet and triplet energy surfaces as well as the equilibrium structures of Fe(CO)(5) ( a singlet state) and Fe(CO)(4) ( a triplet state) has been determined. The partition rational
The associations between educational level, preclinical carotid atherosclerosis and incident coronary events (CE), were investigated in a general population sample of 5399 Swedish middle-aged men and women without history of cardiovascular disease (CVD) over a median follow-up of 8.7 years. Presence of carotid plaque (focal intima-media thickness (IMT) >1.2 mm) was determined by B-mode ultrasound.
Background. Persistent pain is a common problem for older people. Knowledge about how nursing and paramedical staff perceive these people and what they do to relieve the pain seems scarce. Aim. To explore nursing and paramedical staff perceptions of older people in persistent pain and their day-to-day management of pain. Methods. Interviews in Swedish with 52 nursing auxiliaries, Registered Nurs
The Integral Dictionary is a comprehensive lexical network for French, English, German, Italian, and Spanish. It is based on componential semantics and lexical functions. The network structure superimposes two graphs. A first graph consists of a hierarchy of concepts divided into classes and themes where the words form the terminal nodes of the graph. A second graph links the words together using
The purpose of this case report is to describe a new intervention, the Interactive Metronome, for improving timing and coordination. A nine-year-old boy, with difficulties in attention and developmental delay of unspecified origin underwent a seven-week training program with the Interactive Metronome. Before, during, and after training timing, accuracy was assessed with testing procedures consiste
Objective - To analyse potential gender differences in cardiovascular risk factors and treatment patterns, reflecting clinical practice in secondary prevention. Design - Observational national study during 3 years of patients eligible for secondary prevention of coronary heart disease (CHD). Setting - Fifty-two healthcare districts in Sweden, involving primary health care and hospitals in collabor
BACKGROUND: Our recently reported finding of rapid bi-exponential elimination of free prostate-specific antigen (PSA) after radical retropubic prostatectomy in patients with moderately elevated PSA levels, which contrasted a very slow, linear elimination of PSA complexed to alpha-1-antichymotrypsin (ACT), prompted us to study whether these elimination rates were applicable for patients selected fo
Abstract A system for multi-colour fluorescence imaging of tissue is described. The instrument is mainly developed for tissue diagnostics to identify and localise malignant tumours, but might also be useful for real-time monitoring of the therapeutic dose delivered during photodynamic therapy. In vivo examples from various malignant skin lesions following topical δ-amino levulinic acid (ALA) admi
Primary hyperparathyroidism (pHPT) is associated with cardiac disease. This prospective study was designed to investigate changes in cardiac function before and after parathyroidectomy. Resting and post exercise cardiac function was compared with matched control subjects. Fifty patients (mean age 62.9 +/- 11 years, 45 women) and 50 healthy control subjects, matched for age and sex were studied. Re
Background: Dried blood spots (DBS) are a convenient and inexpensive method for biobanking. Although many countries have established population-based DBS biobanks from neonatal screening programs, the quality and usefulness of DNA from DBS have not been extensively assessed. Methods: We compared 4 common DNA extraction methods (Qiagen, EZNA, Chelex 100, and alkaline lysis) in a pilot study using
Two protected derivatives of beta-D-galactopyranosyl-5-hydroxy-L-lysine, in which HO-4 of galactose has been O-methylated or replaced by fluorine, have been prepared. The building blocks were incorporated at position 264 of the peptide fragment CII259-273 from type II collagen by solid-phase synthesis. The ability of these two glycopeptides, and two CII259-273 glycopeptides in which HO-4 of galact
Objective: Several biological activities have been ascribed to islet amyloid polypeptide (IAPP). However, their physiological relevance remains unclear. Previous studies in rats with exogenous administration of IAPP suggest that the peptide may increase splanchnic vascular resistance and redistribute the blood flow within the pancreas to the islets. In this study, the use of IAPP-deficient mice al
Sympatric speciation requires coexistence of the newly formed species. If divergence proceeds by small mutational steps, the new species utilize almost the same resources initially, and full speciation may be impeded by competitive exclusion in stochastic environments. We investigate this primarily ecological problem of sympatric speciation by studying the population dynamics of a diverging asexua
Metal chelate affinity precipitation (MCAP) has been successfully developed as a simple purification process for proteins that have affinity for metal ions. The present lack of widespread applications for this technique as compared to immobilized metal affinity chromatography (IMAC) may be related to the scarcity of well-characterized metal affinity macroligands (AML) and their applications to the
The accumulated experience and path-dependent development of petroleum-based transport fuels and internal combustion engine vehicles has created an apparent technological lock-in. Our analysis of a RApid Future vehicles and Fuels scenario (RAFF) for the EU shows that ambitious carbon emission reductions can be achieved even with projected increases in road transport. Furthermore, escaping the lock
Prolonged inflammation and reactive oxygen species (ROS) generated around an implanted biosensor are the primary causes of the foreign body response, including encapsulation of biosensor membranes. We have previously demonstrated that TiO2 surfaces reduce ROS. Here we investigated the potential of using the anti-inflammatory properties of TiO2 in the design of biosensor membranes with improved lon
