Nuclear magnetic resonance spectroscopy and rheological analysis have been used to investigate the stability of mechanically induced tri-ethylene-glycol-mono-n-decyl-ether (C10E3)/deuterium oxide (D2O) multi-lamellar vesicles (MLVs) and the transition from MLVs to planar lamellae. It was found that MLVs prepared by vortex stirring, relax back to the lamellar phase in a few hours while the relaxati
A major neuropathological feature of Parkinson's disease (PD) is the loss of nigrostriatal dopaminergic neuron. Patients exhibit motor symptoms, including bradykinesia, rigidity, and tremor. Neural grafting has been reported to restore striatial dopaminergic neurotransmission and induce symptomatic relief. The major limitation of cell replacement therapy for PD is the shortage of suitable donor ti
Objective: The aim of this study was to construct a rating scale to predict long-term outcome on the basis of clinical and sociodemographic characteristics in patients with symptoms of psychosis who seek psychiatric help for the first time. Method: Patients (N = 153) experiencing their first episode of psychosis (DSM-IV schizophrenia, schizophreniform disorder, schizoaffective disorder, brief psyc
Objective: To investigate the influence of social capital and individual factors on the level of leisure time physical inactivity in the neighbourhoods. Methods: The public health survey in Malm 1994 is a cross sectional study. A total of 5600 people aged 2080 years were invited to answer a postal questionnaire. The participation rate was 71. A multilevel logistic regression model, with individual
Severe caffeine poisoning is rare but associated with a high mortality. The symptoms are mainly attributable to hyperadrenergic stimulation, are relatively well known and described in the literature. Transient rises in plasma lactate levels may occur but are, however, less well described. We present a case of serious caffeine poisoning with a concomitant rise in lactate treated with a non-selectiv
We present a method for estimating the minimal periodic orbit structure, the topological entropy, and a fat representative of the homeomorphism associated with the existence of a finite collection of periodic orbits of an orientation-preserving homeomorphism of the disk D-2. The method focuses on the concept of fold and recurrent bogus transition and is more direct than existing techniques. In par
The properties of a sol-gel prepared Mn-modified TiO2 film have been studied with X-ray absorption spectroscopy (XAS) and photoelectron spectroscopy (PES) using synchrotron radiation. The chemical composition and oxidation state of the elements have been determined. The manganese content estimated by PES of the Mn-modified film is about 10% and both Mn2+ and Mn3+ are observed. Addition of Mn is fo
Objective: Body mass index (BMI) is associated with increased incidence of cardiovascular disease (CVD). However, the risk could be very different for individuals with the same body mass. The present study explored whether regional fat distribution, as measured by waist-hip ratio (WHR), could modify the impact of BMI on the risk of CVD in men and women. Design: Prospective population-based study.
Drug-induced dyskinesias (DID) manifested as hyperkinetic and/or dystonic movements or postures are common problems in Parkinson's disease (PD). Novel therapeutic interventions may offer possibilities to counteract these common adverse effects of an otherwise necessary treatment. To be able to evaluate the effects of such interventions on DID, reliable and relevant clinical assessment tools are ne
The early marsh orchid, Dactylorhiza incarnata (L.) Soo s. l., grows in medium-rich to rich fens and marshes over much of Europe and parts of Asia. The species is highly polymorphic and different forms may grow together at the same site. In the present study, I tested the hypothesis that these forms represent different migrant populations that have colonized Scandinavia independently of each other
Ferrochelatase is the terminal enzyme in haem biosynthesis, i.e. the enzyme that inserts a ferrous ion into the porphyrin ring. Suggested reaction mechanisms for this enzyme involve a distortion of the porphyrin ring when it is bound to the enzyme. We have examined the energetics of such distortions using various theoretical calculations. With the density functional B3LYP method we calculate how m
Background A genetic component of early-onset lung cancer has been suggested. The role of metabolic gene polymorphisms has never been studied in young lung cancer cases. Phase 1 and Phase 2 gene polymorphisms are involved in tobacco carcinogens' metabolism and therefore in lung cancer risk. Methods The effect of metabolic gene polymorphisms on lung cancer at young ages was studied by pooling data
In an attempt to elucidate the effect of mixing on the rate and extent of enzymatic hydrolysis of cellulosic substrates, alpha -cellulose was hydrolysed using a commercial cellulase preparation at varying levels of substrate concentration (2.5,5 and 7.5% (w/v)) and by using three shaking regimes: continuous at low-speed (25 rpm), continuous at high-speed (150 rpm) and an intermittent regime compri
We propose a new method to reconstruct the electric field of attosecond pulse trains. The phase of the high-order harmonic emission electric field is Taylor expanded around the maximum of the laser pulse envelope in the time domain and around the central harmonic in the frequency domain. Experimental measurements allow us to determine the coefficients of this expansion and to characterize the radi
The paper compares two lexical items, Icelandic ma@?ur and Swedish man, for the construction of a detached, general discourse stance (Berman, Ragnarsdottir and Stromqvist, 2002). Both forms mean 'man', but they can also be used in a generic sense. In that usage, Icelandic ma@?ur is associated with several semantic, pragmatic, and stylistic constraints, whereas Swedish man is more freely applicable
We investigated whether local biotic and abiotic conditions could explain the occurrence of calling males of the declining spadefoot toad Pelobates fuscus in 72 ponds in southern Sweden. The ponds covered the entire distribution range of P. fuscus and were monitored during the breeding season in 2000. Calling males were found in 33 ponds. representing ca 50% of all known ponds for the species ill
