PURPOSE: To determine if the curve length, curve form, and location of the lower-end vertebra can identify the type of scoliosis. METHODS: Standing posteroanterior and lateral radiographs of 78 women and 27 men with scoliosis aged 8 to 32 years were retrospectively analysed. Parameters measured were (1) the curve length (the number of vertebrae in the main curve), (2) the curve form (C-form, inver
The complex reactions of blood coagulation are balanced by several natural anticoagulants resulting in tuned hemostasis. During several decades, the knowledge base of the natural anticoagulants has greatly increased and we have also learned about antiinflammatory and cytoprotective activities expressed by antithrombin and activated protein C (APC). Some coagulation proteins have also been found to
The CryoGrid community model is a flexible toolbox for simulating the ground thermal regime and the ice-water balance for permafrost and glaciers, extending a well-established suite of permafrost models (CryoGrid 1, 2, and 3). The CryoGrid community model can accommodate a wide variety of application scenarios, which is achieved by fully modular structures through object-oriented programming. Diff
In drug discovery, it is of utmost importance to accurately calculate the free energies of binding ligands to various protein targets, such as enzymes and receptors. We have assessed and used computational tools for this aim, most of them based on molecular dynamics (MD) simulations. We mostly used molecular mechanics (MM) in order to model the protein—ligand interactions, which is more approximat
Food encodes social and cultural values and has an important role to play in defining identities. In mixed populations, diet can be used to distinguish between ‘us’ and ‘them’. This study investigates the extent to which the inhabitants of mediaeval Tallinn, an important trading centre, used food to maintain distinct identities. Human skeletal material was selected from four mediaeval cemeteries i
Markstabilisering blir allt vanligare för exploatering av områden med dålig bärighet.Det finns dock behov av bättre och volymstäckande kontrollmetoder förkvalitetssäkring. Kontrollmetoderna kan delas upp i två steg, där det första sker iomedelbar anslutning till inblandning av bindemedel för att kontrollera om manlyckats behandla hela den avsedda volymen, eller om det finns zoner som behöverkompleSoil stabilisation is becoming increasingly common for the development of areas withpoor bearing capacity. However, there is a need for better and volume-wide controlmethods for quality assurance. The control methods can be divided into two steps,where the first takes place in immediate connection to the mixing of binders to checkwhether the entire intended volume has been successfully treated, or
Phytoplankton have short generation times, flexible reproduction strategies, large population sizes and high standing genetic diversity, traits that should facilitate rapid evolution under directional selection. We quantified local adaptation of copper tolerance in a population of the diatom Skeletonema marinoi from a mining-exposed inlet in the Baltic Sea and in a non-exposed population 100 km aw
Holocene relative shore-level changes and development of the Ģipka palaeolagoon in the western Gulf of Riga are reconstructed using multiproxy analyses by combining litho-, biostratigraphical and chronological data with remote sensing and geophysical data. The results show the development of the Ģipka basin from the Ancylus Lake/Initial Litorina Sea coastal zone (before c. 9.1 cal. ka BP) to coast
Purpose: Avian haemosporidians are widespread parasites, occurring in many bird families and causing pathologies ranging from rather benign infections to highly virulent diseases. The state of knowledge about lineage-specific intensities of haemosporidian infection (i.e., parasitaemia) is mainly based on infection experiments conducted under laboratory conditions. The levels and range of parasitae
BACKGROUND: Behavioural therapy for tics is difficult to access, and little is known about its effectiveness when delivered online.OBJECTIVE: To investigate the clinical and cost-effectiveness of an online-delivered, therapist- and parent-supported therapy for young people with tic disorders.DESIGN: Single-blind, parallel-group, randomised controlled trial, with 3-month (primary end point) and 6-m
This paper aims to describe the brownboard tool and to elaborate on its characteristics. Brownboard can be seen as a tool within process mapping and it is focused on supply chain traceability. The process map is created in a dynamical group process where supply chain actors with different competence level meet and interact. The brownboard tool is used in a case study based on a Swedish supply cha
Discussion on social media and their contribution to democratisation is dominated by scholarship on the use of social media in mobilizing and coordinating grassroots opposition in contentious movements (e.g., the Arab Spring). Such approach, however, fails to recognize the power dynamics underlying everyday uses of social media. To fill this gap, this article provides one of the first studies on t
Atypical femoral fractures are insufficiency fractures in the lateral femoral diaphysis or subtrochanteric region that mainly affect older patients on bisphosphonate therapy. Delayed healing is often seen in patients with incomplete fractures (cracks), and histology of bone biopsies shows mainly necrotic material inside the crack. We hypothesized that the magnitude of the strains produced in the s
BACKGROUND: Several major analyses have identified a consistent set of independent risk factors for cutaneous malignant melanoma (CMM). A few prognostic models have been presented but some are based on a limited number of patients and others are based on selected groups of patients referred to major institutions. No nationwide population-based prognostic instrument for survival of CMM has been pre
Synovial fluid was collected from patients with recent knee injury and from patients with early or late stage osteoarthritis. Chondroitin sulfate-substituted aggrecan fragments present in these fluids, and in normal bovine synovial fluid, were purified by cesium chloride gradient centrifugation, enzymically deglycosylated and fractionated by gel filtration on Superose-12. Each sample contained two
Streptococcus pneumoniae is a leading cause of infectious disease globally. Nasopharyngeal colonization occurs in biofilms and precedes infection. Prior studies have indicated that biofilm-derived pneumococci are avirulent. However, influenza A virus (IAV) infection releases virulent pneumococci from biofilms in vitro and in vivo. Triggers of dispersal include IAV-induced changes in the nasopharyn
