Two lesions, actinic keratosis (AK) and squamous cell carcinoma in situ (CIS), are believed to be precursors of squamous cell carcinoma (SCC) of the skin. These lesions can serve as an excellent model system for studying genetic changes associated with the inception of skin SCC. In the present study, five such lesions of the skin, three AKs and two AK+CIS, from three patients were short-term cultu
A technique to estimate fungal growth rates in field samples was tested in soil. The technique is based on the addition of C-14-acetate to a soil slurry and the subsequent uptake and incorporation of the labelled acetate into the fungus specific substance ergosterol by the fungi. The addition of fungal inhibitors decreased acetate incorporation rates, while bacterial inhibitors did not. Fungus-fre
It is generally accepted that mating in flour beetles of the genus Tribolium is mediated by a male-produced aggregation pheromone. The pheromone production site in T. castaneum is believed to be glands on the ventral side of the femur. Behavioural experiments with the confused flour beetle T. confusum were conducted using extracts of beetles and different body parts as well as live beetles to inve
We investigated the class II B genes in a free-ranging population of the ring-necked pheasant Phasianus colchicus by a combination of restriction fragment length polymorphism (RFLP), polymerase chain reaction (PCR), and DNA sequencing. Special attention was paid to the variation in the second exon, which encodes the peptide-binding beta(i)-domain. The population was introduced, but it still exhibi
OBJECTIVES: The aim of this longitudinal study was to test the hypothesis that CSF biomarkers in AD patients also may be forward-looking measures that are associated not only with the degree and profile of cognitive impairment but also with changes in cognition over time. METHODS: Here, we assessed the association of CSF Abeta42, T-tau and P-tau with neuropsychological scores of disease severity,
Emerging nonlinear optical spectroscopies enable deeper insight into the intricate world of interactions and dynamics of complex molecular systems. 2D electronic spectroscopy appears to be especially well suited for studying multichromophoric complexes such as light-harvesting complexes of photosynthetic organisms as it allows direct observation of couplings between the pigments and charts dynamic
Activation of the platelet-derived growth factor (PDGF) beta-receptor leads to cell growth and chemotaxis. The PDGF alpha-receptor also mediates a mitogenic signal, but fails to induce cell migration in certain cell types. To examine this difference in signal transduction, a series of point-mutated PDGF alpha-receptors were analyzed. Porcine aortic endothelial cells expressing mutant PDGF alpha-re
Abstract Adoption of Chinese children with cleft lip and palate (CLP) has become increasingly more common in Sweden. The aim of this study was to examine parents' experience when adopting a child with CLP. Since 2008, 34 adopted children with CLP have been treated in our department. A questionnaire was sent to 33 of the families and 30 of them answered (91%). The parents had queued from 1 month to
Purpose. To examine the effect of an interdisciplinary, out-patient rehabilitation programme for patients with chronic inflammatory arthritis on aerobic capacity and health-related quality of life (HRQOL). Method. One hundred and seventy-four patients, 115 with peripheral arthritis (PA) (91 women, mean age 53 years, disease duration 16 years) and 59 with spondylarthropathies (SpA), (27 women, mean
Antibodies directed towards non-neutralizing epitopes on the factor VIII protein (FVIII) may be detected in patients with haemophilia A. We evaluated the prevalence of non-neutralizing antibodies, in 201 inhibitor-negative brother pairs with severe haemophilia A, enrolled in the Malmö International Brother Study and the Haemophilia Inhibitor Genetics Study. To evaluate binding specificity of the a
OBJECTIVE: Accurate distinction between dementia subtypes is important for patient care and pharmacological treatment. Continuing systematic comparisons of clinical and neuropathological dementia diagnoses may provide a basis for further improvement of the diagnostic procedure. The purpose of this study was to investigate concordance between clinical dementia diagnosis and neuropathological findin
Background: Although the clinical utility of categorically defined attention-deficit hyperactivity disorder (ADHD) is well established, there is also strong evidence supporting the notion of ADHD as an extreme of a continuous trait. Nevertheless, the question of whether the etiology is the same for different levels of DSM-IV ADHD symptoms remains to be investigated. The aim of this study was to as
Activated coagulation factor V functions as a cofactor to factor Xa in the conversion of prothrombin to thrombin. Based on introduction of extra carbohydrate side chains in recombinant factor V, we recently proposed several regions in factor Va to be important for factor Xa binding. To further define which residues are important for factor Xa binding, we prepared fifteen recombinant factor V varia
BACKGROUND: Cardiopulmonary bypass (CPB) affects coronary flow after the operation. Surgical as compared to device closure of atrial septal defect (ASD) serves as a good model to clarify the effects of surgery with CPB on coronary flow. METHODS: Coronary flow parameters were determined by transthoracic Doppler echocardiography before and after ASD closure. Thirteen children underwent surgery on CP
Registry based cancer incidence and mortality data are widely used for etiologic research, cancer control and health care monitoring and planning. The complete coverage of all cases is the key criteria of data quality but it is difficult to assess because the alternative sources of data may be flawed. The aim of this study was to examine, at a nationwide level, the completeness of the Swedish Canc
Forward walking (FW) and backward walking (BW) are two important forms of locomotion in quadrupeds. Participation of the motor cortex in the control of FW has been intensively studied, while cortical activity during BW has never been investigated. The aim of this study was to analyze locomotion-related activity of the motor cortex during BW, and compare it to that during FW. For this purpose, we r
The purpose of this paper was to compare the effects of different data reduction procedures on the values of variables characterizing the time pattern of trapezius muscle activity during full work shifts. Surface electromyography (EMG) of the right and left upper trapezius muscles were obtained from 40 young subjects in different occupations, mainly electricians, hairdressers and students. The tar
