PURPOSE: To describe the unusual appearance of adrenoleukodystrophy (ALD) in MR imaging. MATERIAL AND METHODS: An analysis was made of MR findings, histopathology and clinical course in the cases of two brothers with ALD. RESULTS: The older brother presented with frontal contrast-enhanced lesions, including a cyst. These were initially misinterpreted as a tumour at both radiology and pathology. Th

Decorin and biglycan are closely related abundant extracellular matrix proteoglycans that have been shown to bind to C1q. Given the overall structural similarities between C1q and mannose-binding lectin (MBL), the two key recognition molecules of the classical and the lectin complement pathways, respectively, we have examined functional consequences of the interaction of C1q and MBL with decorin a

Alpha-satellite sequences are found in the centromeric region of all human chromosomes and have been implicated in centromeric function. We describe the structure and behaviour of chromosomes containing amplified human alphoid DNA from chromosome 12, in an osteosarcoma cell line (OSA) and an atypical lipomatous tumour (ALT). In OSA, the amplified material was detected in one large marker chromosom

BACKGROUND: Endothelium dysfunction is believed to play a role in the development of cardiovascular disease. The aim of the present study was to evaluate the suitability of organ culture as a model for endothelium dysfunction. METHODS: The isometric tension was recorded in isolated segments of the rat mesenteric artery branch, before and after organ culture for 20 h. Vasodilatation was expressed a

We examined the response of bacteria and proto- and metazooplankton to photomodified dissolved organic matter (DOM). Sterile filtered water from a eutrophic and a humic lake, that was either exposed to artificial ultraviolet (UV) radiation or kept dark, was added to semicontinuous laboratory microcosms that lasted for 7 weeks. Bacterial production responded positively to photochemical modification

Interpopulation comparisons of variation in resource availability and in allocation patterns along altitudinal and latitudinal gradients allow insights into the mechanisms shaping the life history of animals. Patterns of between-population differences in female life history traits have been studied intensively across a wide range of taxa, but similar investigations in males have remained scarce. T

We report on a novel nonlinear laser spectroscopic technique for single-shot imaging of ground-state hydrogen atoms in harsh environments. H atoms from the ground state were first pumped to the 2s state via a two-photon excitation with a 243 nm laser beam, and the population of the 2s state was further probed through the 2s-4p transition with conventional polarization spectroscopy at 486 nm. A sin

Natural killer (NK) cells are involved both in control of virus infections and in elimination of tumor cells. Killer immunoglobulin-like receptors (KIRs) either activate or inhibit NK cell-mediated cytolysis, protecting healthy cells from destruction while enabling killing of abnormal cells. To investigate whether KIR genes or genotypes are associated with cervical carcinogenesis, a nested case-co

We directly image the interior of GaAs/AlGaAs axial and radial nanowire heterostructures with atomic-scale resolution using scanning tunneling microscopy. We show that formation of monolayer sharp and smooth axial interfaces are possible even by vapor-phase epitaxy. However, we also find that instability of the ternary alloys formed in the Au seed fundamentally limits axial heterostructure control

Abstract in Norwegian Bakgrunn. Fallulykker er et viktig helseproblem hos eldre. Både balansetesting og registrering av egenrapportert funksjon kan være måter å forutse fremtidige ulykker på. Materiale og metode. I en kohortstudie ble egenrapportert gangfunksjon kartlagt hos 307 tilfeldig utvalgte hjemmeboende kvinner 75 år og eldre. Kvinnene gjennomgikk også testing av balanse og gangfunksjon, oBACKGROUND: Falls represent an important health problem among the elderly. Balance testing as well as registration of self-reported balance problems may be appropriate in order to predict the risk of future falls. MATERIALS AND METHODS: Self-reported walking was assessed in 307 randomly selected women 75 years or older living at home. The women underwent testing of gait and balance and were follow

Candida antarctica lipase B (CALB) and Thermomyces lanuginosa lipase (TLL) were evaluated as catalysts in different reaction media using hydrolysis of tributyrin as model reaction. In o/w emulsions, the enzymes were used in the free form and for use in monophasic organic media, the lipases were adsorbed on porous polypropylene (Accurel EP-100). In monophasic organic media, the highest specific act

We used validated outcome instruments to measure symptoms, disability, and health-related quality of life in 58 patients with carpal tunnel syndrome (CTS). The patients completed the CTS instrument before and 6 weeks, 3 months, and 6 months after surgery and the Short Form-36 (SF-36) before and 3 months after surgery. The size of clinical change detected by each outcome measure was estimated by th

In this technical note the ability to estimate surface soil moisture (theta) from soil color using image analysis is evaluated. Four natural soils and uniform fine sand were used. Calibration soil samples with theta varying from 0 to 0.40 m(3) m(-3) in 0.05 m(3) m(-3) increments were prepared and photographed. The variations in soil color with theta were investigated in both the RGB (red, green, a

Software inspection is an effective method to detect faults in software artefacts. Several empirical studies have been performed on reading techniques, which are used in the individual preparation phase of software inspections. Besides new experiments, replications are needed to increase the body of knowledge in software inspections. This paper presents a replication of an experiment, which compar
