During 1980-82, 739 ankle fractures occurred in Malmo. These were compared with 383 ankle fractures occurring in 1950-52. In men there was an increase in the age-specific incidence up to the age of 60, especially in fractures of the lateral malleolus. In women there was an increase in the age-specific incidence above the age of 50, both in lateral malleolar fractures and, even more pronounced, in
To model the structural and functional parts of the water oxidizing complex in Photosystem II, a dimeric manganese(II,II) complex (1) was linked to a ruthenium(II)tris-bipyridine (Ru(II)(bpy)(3)) complex via a substituted L-tyrosine, to form the trinuclear complex 2 [J. Inorg. Biochem. 78 (2000) 15]. Flash photolysis of 1 and Ru(II)(bpy)(3) in aqueous solution, in the presence of an electron accep
Källa on Öland is used as a point of departure in a discussion of the so-called defensive churches or multi-functional churches at the Baltic Sea. The categorization of medieval society into four separate spheres, the church, the castle, the town and the countryside, is criticised as having created a heterogenous group of deviant churches. The deviant churches have been interpreted in three compet
Popular Abstract in Swedish Förståelse av hjärtats pumpförmåga är av yttersta vikt för att kunna behandla patienter med hjärtsjukdom, framförallt hjärtsvikt. Studier av hjärtat har av naturliga skäl framförallt gjorts med öppen bröstkorg eller med hjärtat uttaget ur kroppen, och detta påverkar hjärtats pumpning. Magnetresonans-kameran gör det möjligt att avbilda hjärtat i alla delar av hjärtcykelnCardiac pumping physiology is important for understanding the pathophysiology of patients with cardiac disease. MRI gives the opportunity to measure volumes and flow non-invasively with high accuracy and precision. This thesis examines some aspects on cardiac pumping physiology. Study I showed that the total heart volume in humans decreases during systole by ~8 % (range 5-11 %), and anatomically i
The past decade has witnessed a marked increase in distributed system complexity. This was driven by a maturing technology that steadily decreased the number of faults. Unfortunately these fewer faults have become exponentially more costly. It becomes mandatory to detect faults prior to taking effect on the network. Such an early detection requires a new test detection and fault containment strate
Background: Several studies have found correlations between diabetes and an increased prevalence of periodontitis. Objective: To analyse, in a group of subjects with type 2 diabetes (T2D), (i) the association between medical characteristics and severe periodontal disease and (ii) dental care habits and knowledge of oral health. Methods: One hundred and ninety-one subjects with T2D were examined. B
Objectives: To examine the diameter and distensibility of the abdominal aorta in patients with severe α1-antitrypsin deficiency, and to compare the results with those of normal subjects. Material and methods: Abdominal aortic diameter and stiffness (β) was measured using echo-tracking sonography in 19 men (mean age 50, range 25–79) and 17 women (mean age 46, range 26–62) with severe α2-antitryps
The RISING project was designed to perform high-resolution gamma-ray spectroscopy with radioactive beams at GSI. Unstable beams were produced by fragmentation of relativistic heavy ion projectiles provided by the SIS synchrotron. The fragment separator FRS was used to select and to focus the exotic fragments at about 100A MeV energy on a secondary target. Various charged particle detectors enabled
On the basis of synchronization of three carbon-14 (C-14)-dated lacustrine sequences from Sweden With tree ring and ice core records, the absolute age of the Younger Dryas-Preboreal climatic shift was determined to be 11,450 to 11,390 +/- 80 years before the present. A 150-year-long cooling in the early Preboreal, associated with rising Delta(14)C values, is evident in all records and indicates an
Leukemic stem cells (LSCs) share the capacity of self renewal and extensive proliferation with normal hematopoietic stem cells (HSCs), and are therefore obvious targets for therapy. As such, they need to be identified and characterized in order to elucidate what drives them, and what separates them from their normal counterparts. The focus of this thesis is on pre B cell Acute Lymphoblastic Leukem
Inhibition of oxidative metabolism is often found to decrease contractility of systemic vascular smooth muscle, but not to reduce global [Ca(2+)](i). In the present study, we probe the hypothesis that it is associated with an altered pattern of intracellular Ca(2+) oscillations (waves) influencing force development. In the rat tail artery, mitochondrial inhibitors (rotenone, antimycin A, and cyani
The distribution of persistent pollutants in an eel population from a eutrophic lake of southern Scandinavia was examined. The origin of PCBs, DDT, DDE and lindane found in the fish was most likely the atmosphere. The most important factors for uptake of the chlorinated hydrocarbons was age (exposure time), growth rate and fat content. The life cycle of the eel is unique with a stage in freshwater
Purpose: To estimate the prevalence of severe carpal tunnel syndrome (CTS) that potentially needs surgical treatment in a general population. Methods: A health-status questionnaire was mailed to a random general population sample of 3,000 subjects (ages, 25-74 y). The responders who reported numbness and/or tingling in the median nerve distribution in the hands were asked to attend a clinical eval
This study is an effort to describe and analyse the taphonomic history of skeletal remains of wild boar (Sus scrofa) and red deer (Cervus elaphus) from six Mesolithic sites. Five methods have been used to analyse the effect of different taphonomic processes. A positive correlation between bone element frequency (%MAU) and structural bone density in all but one bone sample (Segebro) indicates high
This work represents an amalgam of a group of studies with the purpose of understanding the influence of the Pacific and Atlantic sea surface temperature on precipitation and river discharge in Northeastern South America. Sea surface temperature is a good representative of phenomena such as ENSO that, in turn, cause worldwide climate variability. The patterns of the Atlantic Ocean sea surface tem
The electronic properties of quantum dot (QD) arrays are strongly influenced by the Coulomb interaction of electrons within the dot as well as with those in neighbouring dots. In this paper, we investigate this behaviour taking into account screening by a free electron gas in the vicinity of the QDs. We find pronounced effects for standard capacitance - voltage ( CV) measurements of QD structures
