The age and sex-specific incidence and prevalence of vertebral compression fractures were compared between the 1950s and 1980s in an urban population. In women over 80 years of age the incidence of symptomatic vertebral fractures has increased approximately four times; in elderly men even more. Mainly, low-energy trauma has caused these fractures. Thus, one clinical manifestation of osteoporosis--
Oats (Avena sativa) are a cereal crop rich in dietary fibre, vitamins, antioxidants, and other nutrients. It is considered to have higher nutritional values compared to other cereals, with a higher fat content (2-13%). Oats also have high content of lipase enzymes when compared to other crops. The high lipase activity is unwanted in oats as it may induce hydrolytic rancidity, with a soapy, bitter
Vascular injuries operated on during a 30-year period (1955-1984) were analyzed. There has been significant increase of such injuries, particularly the iatrogenic types. The total incidence per 100,000 population and year rose from 11.0 to 26.6. Various angiographic and catheterization techniques were responsible for the iatrogenic increase. The noniatrogenic vascular injuries not infrequently wer
SUBJECT: Hypertension represents the most commonly encountered complication of pregnancy. Normal levels of blood pressure (BP) need to be established in each pregnant population in order to recognize pathology. A lack of studies from our own country and certain methodological objections to early studies motivated this study. PATIENTS AND METHODS: Six hundred pregnant women were included in a histo
Popular Abstract in Swedish Den första beskrivningen av diabetes mellitus gjordes redan 1500 före Kristus när en faraos läkare noterade att myror samlade sig omkring urin från vissa människor men inte andras. På 1700-talet beskrevs för första gången närvaron av större mängder socker i såväl blod som urin hos diabetiska patienter. På 1920-talet upptäcktes insulin i bukspottkörteln (pancreas) och saThe influence of trauma (acute pancreatitis) or total parenteral nutrition (TPN) on pancreatic islet hormone secretion in relation to islet expression of inducible nitric oxide synthase (iNOS) was investigated. Acute pancreatitis resulted in an impaired glucose-stimulated insulin secretion (GSIS) which was found to be parallelled by a marked expression of iNOS and an exaggerated NO production in t
An increase in student activity is the goal of various pedagogic approaches and highly valued in most teaching situations. The benefits of student activation are widely discussed in literature (Fox, 1983), but possible drawbacks of such techniques need to be identified and compensations need to be found. This paper discusses a case study concerning one particular course moment, a seminar, held ove
In this Master's thesis I present a means of finding active sources of cortical electrical activity from electroencephalogram (EEG) data acquired during operation of a brain-computer interface (BCI). A novel subspace-based technique was used to suppress spatially correlated EEG interference sources, followed by a technique that estimates the source parameters with a near maximum likelihood per
This thesis investigates the macroeconomic and stock market relationship in Sweden during 2000 – 2015, focusing on the Swedish stock index OMXS30 and the influence from foreign and domestic macroeconomic variables. The analysis covers long-term relationships, causalities and the influence on OMXS30 from short-term shocks in the selected macroeconomic variables. The data is analysed with co-integra
Migratory birds can use a magnetic compass for orientation during their migratory journeys covering thousands of kilometers. But how do they sense the reference direction provided by the Earth's magnetic field? Behavioral evidence and theoretical considerations have suggested that radical-pair processes in differently oriented, light-sensitive molecules of the retina could enable migratory birds t
The current event-related fMRI study examined the relative involvement of different parts of the medial temporal lobe (MTL), particularly the contribution of hippocampus and perirhinal cortex, in either intentional or incidental recognition of famous faces in contrast to unfamiliar faces. Our intention was to further explore the controversial contribution of MTL in the processing of semantic memor
Popular Abstract in Swedish En ordentlig bildning av det centrala nervsystemet är viktigt för ett nyfött barn eller en vuxen. Den senaste tidens kartläggning av människans arvsmassa har lett till identifiering av ungefär 23000 gener, många av dem aktiva i det utvecklande nervsystemet. Men lite är känt om deras funktion och hur de samverkar för att påverka utvecklingen av organ så komplexa som den Morphogens such as Hedghog, Wnt, FGF, and retinoic acid are important signals whose concentrations need to be tightly regulated in the vertebrate embryo to ensure body axis development and formation of the central nervous system. We first show that the intracellular cytoplasmic protein XSufu acts as a dual regulator of Hedgehog (Hh) and Wnt signals during neural induction and patterning in the Xen
The Starmoen dune field is part of a larger aeolian system in the Jomna and Glomma river valleys in southeastern Norway. It is believed to have formed just after the last deglaciation in the area, but no absolute ages have been available to support this. Here, we present a set of quartz optically stimulated luminescence (OSL) ages from the aeolian sediments and the underlying glacifluvial deposits
This study investigated mental workload in basic civil aviation training. Heart rate, eye movement, and subjective ratings from 11 students were collected during simulator and aircraft sessions. Results show high correspondence in psychophysiological reactions between the sessions. For some flight segments, heart rate was consistently lower in the simulator, suggesting higher mental workload in th
Tolerances are an important part of production where the desire to produce quality products have to be weighed against the increased production costs. The desired tolerance will influence the choice of both production method as well as the machine used. Given that machining is an adequate production method, variation of the required surface roughness will imply a variation of the part cost which n
Water samples were collected from streams in west-central Nicaragua at the end of the dry season as part of a study of riverine solutes in volcanic terrains. Streams in volcanic watersheds had lower mean Ca2+ and Mg2+ concentrations (0.29 mM Ca2+; 0.13 mM Mg2+; 0.96 mM Ca2+ and 0.51 mM Mg2+) and slightly higher Ca:Mg molar ratios (2.1) than streams in marine carbonate rocks (1.89). Dissolved Si co
Nixtamalized maize flours elaborated by four factories in Mexico were used for tortilla preparation. Samples were stored at 4°C for up to 72 h and their in vitro starch digestibility features were evaluated. Moisture content was different between flour and tortilla but no evident relation could be established. Protein and lipid levels were lower in tortillas than in flour but ash content was not d
