Macroporous scaffolds composed of chitosan and using oxidized dextran as a crosslinker are produced through cryogelation. Introducing gelatin as a third component into the structure results in the formation of mesopores in the pore walls, which are not seen if gelatin is excluded. The mesoporous structure is explained by the formation of polyelectrolyte complexes between chitosan and gelatin befor

The gradient of five dansylated amino acids in a capillary-based separation system commonly used in capillary liquid chromatography (LC) or capillary electrochromatography (CEC) was followed and examined in detail using a detection method based on laser-induced fluorescence imaging. The detection system consisted of an XeCl excimer laser and an image-intensified charge-coupled device (CCD) camera.

BACKGROUND: Resolution of ST-segment elevation in the electrocardiogram (ECG) is used as a reperfusion sign during thrombolytic therapy in acute myocardial infarction. Analysis of high-frequency QRS components (HF-QRS) might provide additional information. The study compares changes in HF-QRS (150-250 Hz) to ST-segment changes in the standard ECG during thrombolytic therapy. METHODS: Twelve patien

OBJECTIVE: To assess the reliability of 4 gait performance tests in individuals with late effects of polio. DESIGN: An intrarater (between occasions) test-retest reliability study. SETTINGS: University hospital. PARTICIPANTS: Thirty men and women (mean age 63 +/- 6.4 years) with clinically and electrophysiologically verified late effects of polio. INTERVENTION: Not applicable. MAIN OUTCOME MEASURE

C4b-binding protein (C4BP) is best known as a potent soluble inhibitor of the classical and lectin pathways of the complement system. This large 500kDa multimeric plasma glycoprotein is expressed mainly in the liver but also in lung and pancreas. It consists of several identical 75kDa α-chains and often also one 40kDa β-chain, both of which are mainly composed of complement control protein (CCP) d

BACKGROUND: Cardiac magnetic resonance (CMR) is currently considered the reference standard for in vivo assessment of myocardial infarction (MI). There is, however, no international consensus on how MI quantification from CMR should be performed. The aim of this study was to test how previously published manual quantification of MI using CMR images compares with MI quantification using a semiautom

OBJECTIVE: Children who undergo surgery for complex congenital cardiac disease are reported to be at increased thrombotic risk. Our aim was to evaluate long-term changes in the haemostatic system after surgery, to compare markers of activated coagulation in children having surgery with those in a healthy control population, and to relate them to adverse clinical outcome.Patients and methodsWe stud

Neurodegenerative disorders are often associated with metabolic alterations. This has received little attention, but might be clinically important because it can contribute to symptoms and influence the course of the disease. Patients with Huntington's disease (HD) exhibit increased incidence of diabetes mellitus (DM). This is replicated in mouse models of HD, e.g., the R6/2 mouse, in which DM is

Histopathology Analysis of sentinel node biopsy - a single-institution experience supporting the use of serial sectioning and immunohistochemistry for detection of micrometastases by comparing four different histopathological laboratory protocols Aims: Detecting micrometastases (>0.2 and ≤2 mm/>200 cells) and isolated tumour cells (ITCs; ≤0.2 mm/<200 cells) is important for staging of breast cance

PURPOSE OF REVIEW: For optimal asthma control, complementary strategies are advocated to cover several aspects of the disease. This mini-review highlights different complementary strategies with special focus on the combined use of inhaled corticosteroids (ICSs) and long-acting beta2 agonists and as an alternative, the combination of ICSs and antileukotrienes. RECENT FINDINGS: New data show that c

OBJECTIVE: Periodontal ligament (PDL) cells express oestrogen receptors but the functional importance of oestrogen in PDL cells exposed to bacterial endotoxins is not known. Here we investigate if the inflammation promoter lipopolysaccharide (LPS) affects PDL cell production of interleukin-6 (IL-6), monocyte chemoattractant protein-1 (MCP-1), C-reactive protein (CRP) and/or normal functional PDL c

Studies have shown that specific characteristics of prevalent vertebral fractures are associated with a markedly low bone mineral density. This study evaluates if these characteristics also predict subsequent fractures.

Age at injury is believed to be a factor that strongly influences functional outcome after nerve injury. However, there have been few long-term evaluations of the results of nerve repair and reconstruction in children. Our aim was to evaluate the long-term functional outcome of nerve repair or reconstruction at the forearm level in patients with a complete median and/or ulnar nerve injury at a you

OBJECTIVES: To explore the associations between frailty and reproductive axis hormones (as an important regulatory system) in middle aged and older men. DESIGN: Cross-sectional. SETTING: The European Male Aging Study. PARTICIPANTS: Three thousand two hundred nineteen community-dwelling European men aged 40 to 79. MEASUREMENTS: Interviewer-assisted questionnaires to assess physical activity, health

BACKGROUND:: Epidemiological reports on risk and prognostic factors in patients with mesenteric venous thrombosis (MVT) are scarce. METHODS:: Patients with MVT were identified through the inpatient and autopsy registry between 2000 and 2006 at Malmö University Hospital. RESULTS:: Fifty-one patients had MVT, diagnosed at autopsy in six. The highest incidence (11.3 per 100 000 person-years) was in t

We propose an integrated framework for the design of SOC test solutions, which includes a set of algorithms for early design space exploration as well as extensive optimization for the final solution. The framework deals with test scheduling, test access mechanism design, test sets selection, and test resource placement. Our approach minimizes the test application time and the cost of the test acc

The physical and biological mechanisms that extend the equilibrium domain of liquid water into the ice region of the bulk phase diagram are examined in view of their importance for the enhancement of planetary habitability. The physical phenomena studied are the premelting of ice, which allows for films of liquid water at temperatures well below freezing, and the wetting of hygroscopic salts with
