Severe rheumatoid arthritis of the temporomandibular joints and its coincidence with severe rheumatoid arthritis of the cervical spine

The degree of arthritis of the cervical spine was retrospectively studied in cervical spine radiographs from 400 patients with rheumatoid arthritis. In the same cervical radiographs the arthritic destruction of the temporomandibular joints was measured as diminished ramal height from the mandibular angle to the palato-occipital line. Reduced ramal height was found in 76 patients, 69 women and 7 me

Developing an empirical model of stand GPP with the LUE approach: analysis of eddy covariance data at five contrasting conifer sites in Europe

This paper develops a statistical model for daily gross primary production (GPP) in boreal and temperate coniferous forests. The model applies the light use efficiency (LUE) approach, which estimates the conversion efficiency of daily absorbed photosynthetically active radiation (APAR) into daily GPP as a product of potential LUE and modifying factors. The latter were derived from daily total APAR

Versatile mobile lidar system for environmental monitoring

A mobile lidar (light detection and ranging) system for environmental monitoring is described. The optical and electronic systems are housed in a truck with a retractable rooftop transmission and receiving mirror, connected to a 40-cm-diameter vertically looking telescope. Two injection-seeded Nd:YAG lasers are employed in connection with an optical parametric oscillator-optical parametric amplifi

Ballistic imaging of liquid breakup processes in dense sprays

Ballistic imaging is the name applied to a category of optical techniques that were originally developed for medical applications. Recently, ballistic imaging was adapted to acquire instantaneous images of the liquid core inside atomizing sprays; a region that has been heretofore inaccessible to spray researchers. An important difference between spray research and the medical imaging problem is th

Regional Cultural Heritage versus National Heritage in Scania’s Disputed National Landscape

This article argues that the official landscape heritage in Sweden is formed in an interplay between regional and national discourses, and that the national ideology during the last century has promoted the preservation of stereotyped landscapes that partly ignores the conditions under which these landscapes were actually formed. A conclusion is that Skåne's landscape heritage runs the risk of bei

Diagnostics of pulmonary embolism with emphasis of ventilation/perfusion scintigraphy and dead space analysis

Ventilation/perfusion scintigraphy, a first hand method for diagnosis of pulmonary embolism, PE, is challenged by tomography of the pulmonary arteries, CT. An additional method is based upon dead space analysis. Tomographic ventilation/perfusion scintigraphy, V/PSPECT is superior to planar technique. Important is interpretation criteria based upon pattern recognition and clinical information. With

Quality of life in people with severe mental illness. Reliability and validity of the Manchester Short Assessment of Quality of Life (MANSA).

The Manchester Short Assessment of Quality of Life (MANSA) is a short interview, which has received a recent interest in research investigating quality of life in people with mental illness. In the present study, the Swedish version of MANSA is examined with regard to reliability, in terms of internal consistency and construct validity. Ninety-two persons with severe mental illness were interviewe

Involvement of Histidine 190 on the D1 Protein in Electron/Proton Transfer Reactions on the Donor Side of Photosystem II

Flash-induced chlorophyll fluorescence kinetics from photosystem II in thylakoids from the dark-grown wild type and two site-directed mutants of the D1 protein His190 residue (D1-H190) in Chlamydomonas reinhardtii have been characterized. Induction of the chlorophyll fluorescence on the first flash, reflecting electron transport from YZ to P680+, exhibited a strong pH dependence with a pK of 7.6 i

Rose Hip and Lactobacillus plantarum DSM 9843 Reduce Ischemia/Reperfusion Injury in the Mouse Colon.

schaemia/reperfusion (I/R) of the colon is an inflammatory condition that leads to tissue injury where reactive oxygen species play a central role. Rose hip is rich in biologically active polyphenols with antioxidative properties, which may be important in prevention of lipid peroxidation. L. plantarum DSM 9843 possesses enzymatic activity towards polyphenols. The objective of this study was to de

Chlorosis in wild plants: Is it a sign of iron deficiency?

Chlorosis in crops grown on calcareous soil is mainly due to iron (Fe) deficiency and can be alleviated by leaf application of soluble Fe2+ or diluted acids. Whether chlorosis in indigenous plants forced to grow on a calcareous soil is also caused by Fe deficiency has, however, not been demonstrated. Veronica officinalis, a widespread calcifuge plant in Central and Northern Europe, was cultivated

Time-dependent density-functional theory and strongly correlated systems: insight from numerical studies.

We illustrate the scope of time-dependent density-functional theory for strongly correlated (lattice) models out of equilibrium. Using the exact many-body time evolution, we reverse engineer the exact exchange correlation (xc) potential v_(xc) for small Hubbard chains exposed to time-dependent fields. We introduce an adiabatic local density approximation to v_(xc) for the 1D Hubbard model and comp

Bias mediated tuning of the detection wavelength in asymmetrical quantum dots-in-a-well infrared photodetectors

Bias-mediated tuning of the detection wavelength within the infrared wavelength region is demonstrated for quantum dots-in-a-well and dots-on-a-well infrared photodetectors. By positioning the InAs quantum dot layer asymmetrically in an 8 nm wide In0.15Ga0.85As/GaAs quantum well, a shift in the peak detection wavelength from 8.4 to 10.3 mu m was observed when reversing the polarity of the applied

DNA levels in circulating immune complexes decrease at severe SLE flares-correlation with complement component C1q

The objective of this study was to investigate the relationship of DNA content in circulating immune complexes with disease course and activity in SLE. The DNA content in circulating immune complexes containing anti-DNA antibodies of IgG class was determined in serial samples from 28 patients with SLE by a quantitative immunochemical assay. The patients presented various active disease manifestati

CHD7 mutation spectrum in 28 Swedish patients diagnosed with CHARGE syndrome

CHARGE syndrome is a disorder characterized by Coloboma, Heart defect, Atresia choanae, Retarded growth and/or development, Genital hypoplasia and Ear anomalies. Heterozygous mutations in the chromodomain helicase DNA-binding protein 7 (CHD7) gene have been identified in about 60% of individuals diagnosed with CHARGE syndrome. We performed a CHD7 mutation screening by direct exon sequencing in 28

Optimal departure decisions of songbirds from an experimental stopover site and the significance of weather

Recent models have worked with the assumption that birds try to minimize either time, energy or predation risk during migration, or some combination of these. The few empirical studies available have suggested that time minimization may be the most common strategy. One way of distinguishing between strategies is to study the departure decisions of migrating birds. We supplied migrating European ro

Probiotics and Blueberry Attenuate the Severity of Dextran Sulfate Sodium (DSS)-Induced Colitis.

We studied the anti-inflammatory properties of probiotic strains and blueberry in a colitis model. The disease activity index (DAI) was significantly lower on days 9 and 10 in all groups compared to the colitis control. Myeloperoxidase (MPO) and bacterial translocation to the liver and to the mesenteric lymph nodes (MLN) decreased significantly in all groups compared to colitis control. Cecal Ente

Acidification of sandy grasslands - consequences for plant diversity

Questions: (1) Does soil acidification in calcareous sandy grasslands lead to loss of plant diversity? (2) What is the relationship between the soil content of lime and the plant availability of mineral nitrogen (N) and phosphorus (P) in sandy grasslands? Location: Sandy glaciofluvial deposits in south-eastern Sweden covered by xeric sand calcareous grasslands (EU habitat directive 6120). Methods:

Characterization of humoral immune responses against p16, p53, HPV16 E6 and HPV16 E7 in patients with HPV-associated cancers

The cellular tumor suppressor p16 is strongly overexpressed in cervical cancers and precancers. We have previously demonstrated that infiltrating T lymphocytes reactive against p16 can be found in cervical cancer patients. Here, we analyzed whether 16 induces humoral immune responses. Sera of patients with cervical cancer, oropharyngeal cancer, colorectal cancer and autoimmune disease were include
