Association between contact hip stress and RSA-measured wear rates in total hip arthroplasties of 31 patients
BACKGROUND: The main concern in the long run of total hip replacements is aseptic loosening of the prosthesis. Optimization of the biomechanics of the hip joint is necessary for optimization of long-term success. A widely implementable tool to predict biomechanical consequences of preoperatively planned reconstructions still has to be developed. A potentially useful model to this purpose has been
Organising habilitation services: Team structures and family participation
Summary This study is part of a project focusing on co-operation between receivers of habilitation services (families) and professionals. The study focuses on the organisation and co-ordination of the services, and compares two structures for their accomplishment. The first is the typical multiprofessional habilitation team (MHT), and the second is the individualised team (ISP). MHT teams are orga
Osteoarthritis of the peripheral joints
Osteoarthritis (OA) is a complex process affecting many different joint areas in the body. From a pathophysiological point of view some features are crucial for the diagnosis, such as cartilage fibrillation and thinning, subchondral sclerosis and the presence of osteophytes. From a clinical perspective, OA is the most prevalent rheumatic joint disorder, causing pain and stiffness of the joints and
Modeling serum creatinine in septic ICU patients
Serum creatinine is a metabolite assumed to be constantly produced by the normally functioning muscle mass and is a good measure for monitoring daily renal function in the intensive care unit (ICU). High serum creatinine levels or an abnormal departure from normal pre-disease basal levels are indices of acute renal failure (ARF). Septic ICU patients develop multi-organ failure and ARF is often an
Nuclear expression of the Non-B Cell Lineage Sox11 Transcription Factor Identifies Mantle Cell Lymphoma
Mantle cell lymphoma is defined pathologically by the detection of CD20, CD5 and most importantly cyclin D1 (CCND1). Its distinction from other lymphomas is important for prognosis and appropriate therapy but occasional cases may fail to express CCND1 and morphologic simulators may express CD20 and CD5 but not CD23. In this study, we show that the transcription factor Sox11 is specifically express
Quality of life in patients with chronic alveolar hypoventilation
Measurements of health-related quality of life (HRQL) have not been reported in patients with chronic alveolar hypoventilation (CAH) before starting home mechanical ventilation. The purpose of this study was to investigate quality of life in a population of such patients. Forty-four consecutive patients with CAH due to previous polio, scoliosis, healed pulmonary tuberculosis or neuromuscular disea
Fatigue damage assessment for a spectral model of non-Gaussian random loads
In this paper, anew model for random loads - the Laplace driven moving average - is presented. The model is second order, non-Gaussian, and strictly stationary. It shares with its Gaussian counterpart the ability to model any spectrum but has additional flexibility to model the skewness and kurtosis of the marginal distribution. Unlike most other non-Gaussian models proposed in the literature, suc
Genetic and environmental factors affecting reproductive variation in Allium vineale
Traits related to allocation of resources to sexual and asexual reproduction, together with seed production, were-scored on Allium vineale plants sampled from five sites in southern Sweden during a period of 4 years. In addition, random amplified polymorphic DNA (RAPD) fingerprinting of the sampled plants allowed the identification of genets. Integration of genetic and phenotypic data from field a
Formation of der(19)t(1;19)(q23;p13) in acute lymphoblastic leukemia.
The t(1;19)(q23;p13), which results in a fusion of TCF3 (previously E2A) at 19p13 with PBX1 at 1q23, is one of the most common translocations in acute lymphoblastic leukemia (ALL). It is seen either as a balanced t(1;19) or as an unbalanced der(19)t(1;19); occasional cases with coexisting t(1;19)- and der(19)-positive clones also have been described. Although it generally has been assumed that the
Clinical Predictors of Termination and Clinical Outcome of Catheter Ablation for Persistent Atrial Fibrillation
Objectives This study evaluated the role of pre-procedural clinical variables to predict procedural and clinical outcomes of catheter ablation in patients with long-lasting persistent atrial fibrillation (AF). Background Catheter ablation of persistent AF remains a challenging task. Methods Catheter ablation was performed in 90 patients (76 men, age 57 +/- 11 years) with long-lasting persistent AF
The likely impact of elevated CO2, nitrogen deposition, increased temperature, and management on carbon sequestration in temperate and boreal forest ecosystems. A literature review
Temperate and boreal forest ecosystems contain a large part of the carbon stored on land, in the form of both biomass and soil organic matter. Increasing atmospheric [CO2], increasing temperature, elevated nitrogen deposition and intensified management will change this C store. Well documented single-factor responses of net primary production are: higher photosynthetic rate (the main [CO2] respons
Nocturnal vision and landmark orientation in a tropical halictid bee
Background: Some bees and wasps have evolved nocturnal behavior, presumably to exploit night-flowering plants or avoid predators. Like their day-active relatives, they have apposition compound eyes, a design usually found in diurnal insects. The insensitive optics of apposition eyes are not well suited for nocturnal vision. How well then do nocturnal bees and wasps see? What optical and neural ada
Rectifying and Sorting of Regenerating Axons by Free-Standing Nanowire Patterns: A Highway for Nerve Fibers
We present an EBL-defined nanowire pattern that can sort axons coming from different directions on a substrate. The pattern defines tracks for left-bound traffic and right-bound traffic, which opens up new possibilities for designing neural networks on a chip.
Changing the Mechanical Unfolding Pathway of FnIII(10) by Tuning the Pulling Strength
We investigate the mechanical unfolding of the tenth type III domain from fibronectin (FnIII(10)) both at constant force and at constant pulling velocity, by all-atom Monte Carlo simulations. We observe both apparent two-state unfolding and several unfolding pathways involving one of three major, mutually exclusive intermediate states. All three major intermediates lack two of seven native beta-st
C-erbB2, p27 and G1/S aberrations in human primary breast cancer
Background: C-erbB2 is overexpressed in approximately one-fourth of human breast cancers. In spite of numerous reports suggesting a connection of c-erbB2 overexpression with cell cycle regulation through p27, D cyclins and c-myc. the relationship between c-erbB2 and proliferation through de-regulation of the pRb pathway in primaty breast cancer has not been fully clarified. Materials and Methods:
Long-term treatment and suicidal behavior in severe depression: ECT and antidepressant pharmacotherapy may have different effects on the occurrence and seriousness of suicide attempts.
Our objective in this article is to assess the relation between long-term treatments of depressive episodes and attempted or completed suicide in patients who had had a severe depression at index admission. A blind record evaluation of 96 suicides with a primary severe depression and matched controls has been performed. Out of those, 57 and 33, respectively, bad made suicide attempts. Occurrence o
Joint effects of different human papillomaviruses and Chlamydia trachomatis infections on risk of squamous cell carcinoma of the cervix uteri
This case-control study based in Nordic serum banks evaluated the joint effects of infections with genital human papillomavirus (HPV) types, and Chlamydia trachomatis in the aetiology of cervical squamous cell carcinoma. Through a linkage with the cancer registries, 144 cases were identified and 420 controls matched to them. Exposure to past infections was defined by the presence of specific IgG a
The pattern of variation in leaflet shape and reproductive characters in Lathyrus vernus (L.) Bernh. (Fabaceae)
The pattern of variation in characters closely connected with reproductive fitness and in a presumably weakly selected character, leaflet shape, was studied in the forest-herb Lathyrus vernus. Plants from twenty populations, representing three geographically distinct regions (C. Europe, S. Sweden and C. Sweden), were transplanted to a common garden. Leaflet shape, described using elliptic Fourier
An exact ab initio theory of quantum transport using TDDFT and nonequilibrium Green's functions
We present an exact ab initio theory for describing the motion of interacting electrons through nanoscopic constrictions. Our theory is based on time-dependent density functional theory (TDDFT) and nonequilibrium Green functions. We consider the system electrode-device-electrode initially contacted and in equilibrium, therefore the scheme is thermodynamically consistent. Besides the steady-state r
