A new approach in affinity separations was studied by partitioning of Cellulomonas fimi beta-mannanase (EC 3.2.1.78) containing a mannan-binding module in galactomannan/hydroxypropyl starch aqueous two-phase system. Comparison was made with a truncated version of C. fimi beta-mannanase which lacked the mannan-binding module. Results showed that affinity partitioning of the beta-mannanase was achie
Gm allotypes are genetic variants of the immunoglobulin heavy G chains (IGHG) of IgG molecules, coded from chromosome 14q32, characterized by differences in amino acid epitopes of the constant heavy G chains and inherited in the Mendelian manner. Gm allotypes have influence on IgG subclass levels, and serum Gm allotype levels have been given for different Gm genotypes in adults. Four hundred and t
Almost all articles on education in medical ethics present proposals for or describe experiences of teaching students in different health professions. Since experienced staff also need such education, the purpose of this paper is to exemplify and discuss educational approaches that may be used after graduation. As an example we describe the experiences with a five-day European residential course o
A large pulse of atmospheric Cl-36 generated by a limited number of nuclear tests peaked in the late 1950s to early 1960s. The corresponding enhanced Cl-36 deposition is seen in various glaciological archives in the Northern Hemisphere. The profile of the bomb spike recorded in firn layers at Vostok Station, central East Antarctica. has been measured by employing accelerator mass spectrometry (AMS
Nanoparticles were used as a pseudostationary phase in capillary electrochromatography (CEC) electrospray ionisation-mass spectrometry (ESI-MS) for separation of both neutral analytes by a reversed phase mechanism, as well as for cationic analytes by a cation exchange mechanism. Nanoparticles suspended in electrolyte, were injected as a plug prior to the sample using a partial filling technique (P
Work in rodents has shown that cultured retinal progenitor cells (RPCs) integrate into the degenerating retina, thus suggesting a potential strategy for treatment of similar degenerative conditions in humans. To demonstrate the relevance of the rodent work to large animals, we derived progenitor cells from the neural retina of the domestic pig and transplanted them to the laser-injured retina of a
This paper outlines a four step effort estimation study and focuses on the first and second step. The four steps are formulated to successively introduce a more formal effort experience base. The objective of the study is to evaluate the needed formalism to improve effort estimation and to study different approaches to record and reuse experiences from effort planning in software projects. In the
The tars from an air-blown pressurized bubbling fluidized bed 90 kW (thermal) pilot biomass gasifier and also from an 18 MW IGCC demonstration plant were analyzed. The accuracy of the sampling method and its advantage/disadvantage was compared with other methods.
The inner relative humidity (RH) and degree of saturation (S) of high-performance concrete cured for 2 years in water or 3% NaCl solution were measured at three different levels from the concrete surface (outer layer 0 to 16 mm, middle layer 16 to 32 mm, and inner layer 32 to 50 mm). The effects of many factors, such as water-to-cement (w/c) ratio, content of silica fume, and air content, were inv
Popular Abstract in Swedish Depression är en mycket vanlig och allvarlig sjukdom som drabbar ett stort antal människor någon gång i livet. På jakt efter effektiv antidepressiv behandling har forskare inom det medicinska fältet sökt efter biologiska processer kopplade till sjukdomen. På senare tid har ett flertal undersökningar visat att depression leder till förändringar inom vissa områden av hjärThe aim of the current thesis was to investigate glial responses to electroconvulsive seizures (ECS), an animal model of the fast-acting antidepressant treatment electroconvulsive therapy (ECT). Depression, a common and devastating disorder, has in recent years been associated with volumetric changes in prefrontal cortex, hippocampus and amygdala, brain regions known to be implicated in emotional
The aim of this study was to describe employers experiences of a work rehabilitation planning process at the workplace and how it can be improved according to quality and cost-effectiveness. Qualitative interviews were performed with 10 employers of employees that had participated in in vocational rehabilitation at a rehabilitation centre in the north of Sweden.The results showed that employers we
Popular Abstract in Swedish Utbredningen av besvär som attribueras till elektrisk utrustning respektive kemikalielukter och andra odörer är ännu ej till fullo fastställd. Vidare saknas kunskap om eventuella bakomliggande faktorer för dessa besvärs uppkomst. Syftet med avhandlingen var att undersöka utbredningen av besvär som attribueras till elektriska faktorer, kemikalier och lukter, samt undersSelf-reported annoyance from electrical equipment has been in evidence since the mid-eighties, and the first reports of illness from everyday chemicals arose already in the 1960?s. However, the extent of the problem or the mechanisms behind the development of environmentally related annoyance has not yet been fully established. Increased vulnerability to stress has been suggested to be a possible
Do the CNS monoaminergic (MA) systems regulate thyroid hormone metabolism in humans? In 23 unmedicated, male, violent offenders without signs of thyroid disease, we found positive correlations between the catecholaminergic CSF metabolites HVA and MHPG and the peripheral T3/T4 ratio (rho=0.55, p=0.010 and 0.51, p=0.018), indicating that increased activity in the brain MA systems, especially the dop
