Huntington's disease (HD) is a hereditary neurodegenerative disorder characterized by progressive psychiatric, cognitive, and motor disturbances. We studied the expression of synaptic vesicle proteins in the R6/1 transgenic mouse model of HD. We observed that the levels of rabphilin 3A, a protein involved in exocytosis, is substantially decreased in synapses of most brain regions in R6/1 mice. The

Kaposi sarcoma-associated herpesvirus (KSHV) is the most important etiopathological factor of Kaposi's sarcoma (KS) and some specific types of malignant lymphomas. One of the viral lytic genes encodes the KSHV complement control protein (KCP), which functionally mimics human complement inhibitors. Although this protein provides an advantage for evading the complement attack, it can serve as target

PRELP (proline, arginine-rich end leucine-rich repeat protein) is an extracellular matrix leucine-rich repeat protein. The amino-terminal region of PRELP differs from that of other leucine-rich repeat proteins in containing a high number of proline and arginine residues. The clustered proline and basic residues are conserved in rat, bovine, and human PRELP. Although the function of PRELP is not ye

Six years' runoff data from Bensbyn Research Watershed (BRW) in northern Sweden is discussed. BRW is 1.6 km2, out of which 0.5 km2 is a large meadow and the remaining area consists of a dense coniferous forest. In the runoff analysis, runoff contribution from the meadow is separated from that from the forest. Peak flows are related to snowmelt from each separate area, and to rain events. The snowm

Objective. To assess the interaction between cystatin C (CysC) and serum amyloid A protein (SAA). Methods. Levels of CysC and SAA and antibodies against these proteins were assessed in the paired blood and synovial fluid (SF) samples of 90 patients with rheumatoid arthritis (RA). Age and sex matched individuals having normal iohexol clearance (n = 90) and SF following joint trauma (n = 40) were us

Factor IX is a vitamin K-dependent zymogen of a serine protease. The NH2-terminal half of the molecule consists of a Ca(2+)-binding gamma-carboxyglutamic acid (Gla)-containing module and two modules homologous to the epidermal growth factor (EGF) precursor. To elucidate the role of these non-catalytic modules of factor IXa beta in factor X activation, we have isolated and characterized fragments o

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

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 (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

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

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

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

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

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

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

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

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

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
