The increased schizophrenia risks for residents of cities with high levels of competition and for members of disadvantaged groups (for example migrants from low- and middle-income countries, people with low IQ, hearing impairments or a history of abuse) suggest that social factors are important for aetiology, Dopaminergic dysfunctioning is a key mechanism in pathogenesis. This editorial is a selec
We have studied the pH effect on the S0 and S2 multiline electron paramagnetic resonance (EPR) signals from the water-oxidizing complex of photosystem II. Around pH 6, the maximum signal intensities were detected. On both the acidic and alkaline sides of pH 6, the intensities of the EPR signals decreased. Two pKs were determined for the S0 multiline signal; pK1 = 4.2 ± 0.2 and pK2 = 8.0 ± 0.1, and
It is essential to label roads, landmarks, and other important features on maps for mobile applications to help users to understand their location and the environment. This paper aims to examine real-time map labelling methods suitable for the small screen on mobile devices. A slider method with a continuous search space was proposed to sequentially label both line and point features. The method s
The genomic response following brain ischemia is very complex and involves activation of both protective and detrimental signaling pathways. Immediate early genes (IEGs) represent the first wave of gene expression following ischemia and are induced in extensive regions of the ischemic brain including cerebral cortex and hippocampus. Brain-derived neurotrophic factor (BDNF), Neuritin and Activity-r
The distribution of substituents along the polymer backbone will have a strong influence on the properties of modified cellulose. Endoglucanases were used to degrade three different batches of hydroxypropyl methyl cellulose ( HPMC) derivatives with similar chemical properties. The phase separation of the HPMCs as a function of temperature, i.e., the clouding behavior, was analyzed prior to degrada
The chromosomal translocation t(X;18)(p11.2;q11.2) is tightly linked to the tumorigenesis of synovial sarcoma. Through this translation the SYT gene on chromosome 18 is fused with a testis/cancer antigen gene on the X chromosome, generating either a SYT-SSX1, SYT-SSX2, or less often a SYT-SSX4 fusion gene. It has been anticipated that the individual synovial sarcoma carries only one of these varia
In Swedish welfare agencies, it was found that the importance of characteristics of social research for utilization was related to three intervening factors: the context of origin of the research, the functions for the user and the utilization context. These factors seem to explain the difference between competing notions on the importance of scientific sophistication for research utilization.
In this study, the reproducibility of tryptic digestion of complex solutions was investigated using liquid chromatography Fourier transform ion cyclotron resonance (LC FT-ICR) mass spectrometry. Tryptic peptides, from human cerebrospinal fluid, (CSF) were labeled with Quantification-Using-Enhanced-Signal-Tags (QUEST)-markers, or 1-([H-4]nicotinoyloxy)- and 1-([D-4]nicotinoyloxy)-succinimide ester
This paper presents newly constructed series on human capital in Sweden 1870–2000. The estimates are based on enrolment in different forms of education, stretching as far back as 1812, and the size and age distribution of the population within age range 15–65 years. The secular accumulation of human capital has closely matched the long-term trend in aggregate productivity and both grew at a rate o
Abstract in UndeterminedWe suggest a method of analyzing the sustainability conditions for forestry from three major realms: environmental, social, and economic. The tools and methods were tested at sites in Sweden. Assessments were made for the long-term sustainability concerning the impact of present management practices on the balances of nutrients in monocultures and mixed-species stands. In t
Acute rheumatic fever is a serious autoimmune sequela of pharyngitis caused by certain group A streptococci. One mechanism applied by streptococcal strains capable of causing acute rheumatic fever is formation of an autoantigenic complex with human collagen IV. In some geographic regions with a high incidence of acute rheumatic fever pharyngeal carriage of group C and group G streptococci prevails
The concept of a very limited effective period for prophylactic antibiotic action was challenged in a prospective, controlled and randomized study featuring a simplified method for assessing the degree of contamination in the operative field during colorectal surgery. The 226 patients were given 1 g metronidazole IV on induction of anaesthesia and 12 h postoperatively. Following standardized salin
In this study, age and sex differences in diameter and compliance of the common carotid artery (CCA) were evaluated in 119 healthy subjects with a phase-locked echo-tracking system. The diameter and pulsatile diameter changes were measured, and pressure strain elastic modulus (Ep) and stiffness (beta) were calculated and used as the inverse estimate of compliance. The carotid diameter increased mo
The alkaline sphingomyelinase (SMase) was first found in rat intestinal brush border. The important roles of this enzyme in digestion of sphingomyelin and in mucosal cell proliferation have been suggested. In the present work, the distribution of the alkaline SMase in the tissues of human beings and animals have been studied. By assaying the enzyme activity in human biopsy samples, we found that t
We report on the mechanism of growth of mesoporous silica (SBA-15, plane group p6m). In situ studies of the formation using ultrasmall angle X-ray scattering (USAXS) and small-angle X-ray scattering (SAXS) covering length scales from 5 to 10 000 A, complemented with UV-vis and transmission electron microscopy (TEM), provide unique data on particle growth coupled with information regarding the prog
The lecticans are a group of chondroitin sulfate proteoglycans characterized by the presence of C-type lectin domains. Despite the suggestion that their lectin domains interact with carbohydrate ligands, the identity of such ligands has not been elucidated. We previously showed that brevican, a nervous system-specific lectican, binds the surface of B28 glial cells (Yamada, H., Fredette, B., Shitar
Dizziness is a common symptom, and recent research shows that physical activity and specific treatment of vertigo and dizziness are effective. The management of dizzy patients requires assessment and, when appropriate, treatment by a physiotherapist. We have therefore studied how general practitioners (GPs) handle patients with vertigo and dizziness, to find out whether treatment follows current r
