Purpose: To investigate the clinical value of assessment of peripapillary retinal nerve fibre layer (RNFL) thickness with OCT in addition to the evaluation of retinal function measured by full-field electroretinography (ff-ERG) in patients with suspected vigabatrin (VGB)-attributed visual field defects. Methods: Visual fields from adult patients in our clinical follow-up program for VGB medication
BACKGROUND: It is controversial whether breast reconstruction with a microvascular free flap should be done without restrictions in patients who have not had radiotherapy. Many regard it as too expensive, but some consider it better and more economically advantageous than an implant reconstruction. METHODS: Databases of publications were searched to find out under what conditions is it suitable to
This study examines the management of used mobile phones in the United Kingdom between 2005 and 2008. It shows that the replacement cycle for mobile phones got shorter during the period due to heavy handset subsidies given by mobile network operators. The planned obsolescence presented a business opportunity for the exports of used phones to developing countries. However, the collection for re-use
This paper discusses the results of a time-dynamic analysis of the possible effects of government and utility-sponsored energy-efficiency programs on electric energy use in Swedish commercial buildings. In the study, which includes efficient lighting, improvements in ventilation, commercial cooling and cooking, we use energy scenarios to analyse how policy measures can effect future energy demand.
A statistical distribution for the number of CDMA RAKE fingers, N T, to be assigned in order to track a given percent of the total received power has been derived. The obtained distribution reveals a strong dependence of NT on the system bandwidth, the median RMS delay spread, its standard deviation and other environment specific parameters. Also, a statistical distribution for the fading width fw
The typical catalyst layers (CLs) in proton exchange membrane fuel cells (PEMFCs) are fabricated as random heterogeneous composites to meet the multifunctional requirements of transport phenomena and electrochemical activity. The employment of Pt nano-particles, carbonaceous substrates and Nafion ionomers in CLs allows effective diffusion of hydrogen and oxygen, transport and phase change of water
Popular Abstract in Swedish Upptag och omsättning samt dosimetri för 14C märkt fett, urea, gallsyra och xylos, i människa. Kol-14 (14C) används som radioaktivt spårämne vid patientundersökningar inom sjukvården och utnyttjas i stor utsträckning vid medicinsk forskning och vid utprovning av nya läkemedel på frivilliga försökspersoner. Eftersom 14C har mycket lång fysikalisk halveringstid (5730 år)14C-labelled substances have been used in biomedical research and clinical medicine for over 50 years. Physicians and scientists however, often hesitate to use these substances in patients and volunteers because the radiation dosimetry is unclear. In this work detailed long-term biokinetic and dosimetric estimation have been carried out for four clinically used 14C-breath tests: 14C-triolein (exam
The Major Intrinsic Proteins, MIPs, constitute a large, ancient superfamily of membrane proteins that are found in all kingdoms of life. Most MIPs facilitate passive diffusion of water across biological membranes (aquaporins), although many channels are also permeable for glycerol and other small uncharged solutes, (aquaglyceroporins). Other substrates reported for specific MIPs are anions, carbon
Abstract in UndeterminedThe importance of computer learner corpora for research in both second language acquisition and foreign language teaching is rapidly increasing. Computer learner corpora can provide us with data to describe the learner's interlanguage system at different points of its development and they can be used to create pedagogical tools.In this paper, we first present a new computer
When biomass is used to produce fuels and green products by thermochemical conversion, the ability to handle or remove the fine particle phase in the product gas is crucial. The product gas from biomass gasification contains relatively volatile organic compounds (“tar”) condensed on nonvolatile cores of, for example, aggregated soot particles and char. The problems are, for example, that particles
Popular Abstract in Swedish Syftet är att utifrån studenters livsberättelser, få kunskap om och förståelse för hur de upplever och hanterar sjuksköterskeutbildningens olika delar med särskilt fokus på spänningsfälten mellan: yrkesexamen ? akademisk examen, högskoleförlagd utbildning ? verksamhetsförlagd utbildning samt huvudämnet omvårdnad ? stödämnet medicinsk vetenskap. Syftet är vidare att få kThe aim of this study is to gain knowledge and understanding of how nursing students experience and manage the different parts of the education. A particular focus is set on the tension between a professional degree and an academic degree, between theoretical and clinical studies, and between the subjects nursing and medical science. Furthermore, the aim is to gain knowledge and understanding of a
This work concerns the performance of an oxidation catalyst used in a NOx storage and reduction system. The oxidation of NO is the main objective of this study, where the presence of CO and propene has also been taken into account. Experimental data has been determined on a monolithic oxidation catalyst mounted after a heavy duty diesel engine in a rig. The conversion of hydrocarbons is predicted
Data from finished projects may stay in a researcher’s mind for many reasons: a fascination for a field, members’ charm, odd circumstances in the collecting process, analytical frustration etc. Yet the possibility of bringing back one’s attention to these data in order to understand them in new conceptual contexts is rarely as valued as the opposite: a quest for new data to be put in one’s famili
Although the beneficial effect on breast cancer of adjuvant tamoxifen (TAM) is well established, in the series studied by our group this effect seems to have been restricted to patients with steroid receptor (especially progesterone receptor (PgR)) positive tumors. However, as some patients with PgR-positive tumors manifested recurrence despite adjuvant TAM treatment, the question arose whether so
The reported rate of detection of Chlamydia pneumoniae DNA within atherosclerotic lesions by PCR varies between 0 and 100%. In this study, identical sets of coded experimental atheroma samples (n = 15) and spiked controls (n = 5) were analyzed by 16 test methods in nine centers by means of PCR. The positive controls were correctly identified to levels of 1, 0.1, and 0.01 inclusion bodies of C. pne
