Steroid injections are often employed as an alternative treatment for radicular pain in patients with degenerative spinal disorders. Prospective randomised studies of the lumbar spine reveal contradictory results and non-randomised and most often retrospective studies of the cervical spine indicate pain reduction from steroid injections. No prospective randomised study on transforaminal steroid in
We present the identification of the sex pheromone in the pine sawfly, Gilpinia pallida, including analysis of the female pheromone content, male antennal response and attraction in the field, and synthesis of the most active pheromone component. Several 3,7-dimethyl-2-alkanols were identified from female whole-body extracts, including some compounds with a 2R configuration. This is the first obse
The aim of this study was to explore the previous personalities of patients, their behavior during the course of the disease, and the relationship between the previous personality and vocally disruptive behavior of severely demented patients. Twenty-one severely demented patients identified as vocally disruptive and 19 severely demented control subjects who were matched for gender and ward were st
A suite of analyses was performed on sediments accumulated during the last 10 700 years in Lake Spaime, a small, hydrologically open water body in the modern alpine tundra zone of the Scandes Mountains, west-central Sweden. The study aimed to evaluate (1) the nature of climate changes that forced the late-Holocene lowering of altitudinal tree limit in the region, the timing of which is known from
Mutations in the PTEN gene are associated with a broad spectrum of disorders, including Cowden syndrome (CS), Bannayan-Riley-Ruvalcaba syndrome, Proteus syndrome, and Lhermitte-Duclos disease. In addition, PTEN mutations have been described in a few patients with autism spectrum disorders (ASDs) and macrocephaly. In this study, we screened the PTEN gene for mutations and deletions in 88 patients w
The importance of neuropeptide Y (NPY) and Y2 receptors in the regulation of bone and energy homeostasis has recently been demonstrated. However, the contributions of the other Y receptors are less clear. Here we show that Y1 receptors are expressed on osteoblastic cells. Moreover, bone and adipose tissue mass are elevated in Y1(-/-) mice with a generalized increase in bone formation on cortical a
Hematopoietic stem cell lineage choices are decided by genetic networks that are turned ON/OFF in a switch-like manner. However, prior to lineage commitment, genes are primed at low expression levels. Understanding the underlying molecular circuitry in terms of how it governs both a primed state and, at the other extreme, a committed state is of relevance not only to hematopoiesis but also to deve
We investigated the orientation of juvenile pied flycatchers, Ficedula hypoleuca, during autumn migration in south Sweden using orientation cage experiments, to study the relative importance of visual and magnetic information at sunset. We performed cage tests under 12 experimental conditions that manipulated the geomagnetic and visual sunset cues available for orientation: natural clear skies in
Platelet deposition onto double velour Dacron (n = 14) and double velour Dacron with internal collagen (n = 14) interposition grafts were examined experimentally. The accumulation was assessed by reinfusion of 111In labelled platelets and imaging with a scintillation camera. One group received Dextran-40 intravenously (n = 14) and one group received Dazmegrel (n = 14) intravenously. No graft occlu
Background and Purpose - Warfarin prevents stroke in atrial fibrillation (AF); however, concerns regarding international normalized ratio control and hemorrhage limit its use in the elderly. The oral direct thrombin inhibitors (DTIs) are potential alternatives to warfarin, offering fixed dosing without drug and dietary interactions and the need for international normalized ratio monitoring. Althou
Objective: To develop calculation models, using Western immunoblot, as a tool for the estimation of proteolytic human aggrecan fragment identity. Method. Seven human aggrecan fragments (calibrators), purified by CsCl gradient centrifugation and identified by Western immunoblot of N- and C-terminals, were used to develop calculation models. The models were used for identification of unknown aggreca
Extraskeletal myxoid chondrosarcoma (EMC) is a soft-tissue neoplasm cytogenetically characterized by the translocations t(9;22)(q22;q11-12) or t(9;17)(q22;q11), generating EWS/CHN or RBP56/CHN fusion genes, respectively. In the present study, 18 EMCs were studied both cytogenetically and at the molecular level. Chromosomal aberrations were detected in 16 samples: 13 with involvement of 9q22 and 22
The effect of friction between the dowel and the surrounding timber was studied for single dowel-type joints. The joints tested were divided into two groups of joints, where the surface of the dowels differed. For the first group, the dowels had a smooth surface and for the second group the dowels had a rough surface. A contactfree measurement technique was used in the experimental investigatio
Electron-ion-ion coincidence measurements of sulfur dioxide at discrete resonances near the O 1s ionization edge are reported. The spectra are analyzed using a model based upon molecular symmetry and on the geometry of the molecule. We find clear evidence for molecular alignment that can be ascribed to symmetry properties of the ground and core-excited states. Configuration interaction (CI) calcul
Proteinlike copolymers were first predicted by the computer-aided biomimetic design (Physica A 1998, 249, 253-261). These copolymers consist of comonomer units of differing hydrophilicity/hydrophobicity. Heterogeneous blockiness, characteristic for such copolymers, facilitates chain folding with the formation of specific spatial packing: a dense core consisting of hydrophobic units and a polar she
Background-The objective was to evaluate the role of risk factors and stent type for stent thrombosis (ST) using a large real world registry. Methods and Results-We evaluated all consecutive coronary stent implantations in Sweden from May 1, 2005, to June 30, 2007. All cases of ST, documented in the Swedish coronary angiography and angioplasty registry until September 21, 2008, were analyzed. ST w
Early environmental factors and genetic variants have been reported to be involved in the pathogenesis of type 2 diabetes. The aim of this study was to investigate whether there is an interaction between birthweight and common variants in the TCF7L2, HHEX, PPARG, KCNJ11, SLC30A8, IGF2BP2, CDKAL1, CDKN2A/2B and JAZF1 genes in the risk of developing type 2 diabetes. A total of 2,003 participants fro
To study gene expression in differentiated adult motoneuron subtypes, we used fluorescent dextrans for both anterograde and retrograde axonal tracing in adult rat and mouse. Application of these dyes to the cut distal and proximal ends of small extramuscular nerve branches revealed both the peripheral ramifications and the cell bodies of subsets of motoneurons. We show that the soleus muscle is in
In this chapter, I discuss some effects on the ‘creative classes’ in Sweden and Scandinavia due to developments during roughly the last decade. In this period, a majority of the feature film making but also some documentary and TV-production has moved away from Stockholm, the capital, to newly established, regional production centres. A similar process has been going on for a while in other parts
Popular Abstract in Swedish Arbetet som presenteras i denna avhandling handlar om att utveckla nya processer för att producera gasformiga biobränslen som är mer energieffektiva än de som används idag. Genom att göra processerna mer energieffektiva kan kostnaden för att producera biobränslen minskas. En lägre produktionskostnad för biobränslet gör det lättare att ersätta fossila bränslen med förnyeReplacing fossil fuels with biofuels is one way of reducing the emission of greenhouse gases into the atmosphere, thus decreasing our impact on the global climate. For this to be a viable option, several production routes are needed, as no single option can fully replace fossil fuels. One way of making biofuels more competitive with fossil fuels is by reducing the production cost. As most of the p
