Deficiencies of complement proteins of the classical pathway are strongly associated with the development of autoimmune diseases. Deficiency of Clr has been observed to occur concomitantly with deficiency in Cls and 9 out of 15 reported cases presented systemic lupus erythernatosus (SLE). Here, we describe a family in which all four children are deficient in Cls but only two of them developed SLE.
Satellite-derived Normalized Difference Vegetation Index (NDVI), a proxy of vegetation productivity, is known to be correlated with temperature in northern ecosystems. This relationship, however, may change over time following alternations in other environmental factors. Here we show that above 30°N, the strength of the relationship between the interannual variability of growing season NDVI and te
Mediterranean diet has been suggested to explain why coronary heart disease mortality is lower in southern than northern Europe. Dietary habits can be revealed by isotope ratio mass spectrometry (IRMS) measurement of carbon (δ(13)C) and nitrogen (δ(15)N) in biological tissues. To study if diet is associated with human plaque stability, atherosclerotic plaques from carotid endarterectomy on 56 pati
Popular Abstract in Swedish Det traditionella jordbruket i nordvästra Europa har gynnat förekomsten av många arter under tusentals år och den snabba övergången till modernt jord- och skogsbruk har lett till försämrade förutsättningar för dessa arter. Både internationellt och nationellt finns strategier för att bevara biologisk mångfald. I Sverige är dessa strategier integrerade i miljömål med ansThis thesis explores the relationship between land-use and floristic diversity over the last three millennia in the uplands of southern Sweden. A quantitative approach based on high-resolution pollen data was applied, using the Landscape Reconstruction Algorithm (LRA), historical maps/aerial photographs, palynological richness and new ways to estimate past evenness at regional and local spatial sc
The fast timing beta gamma gamma(t) method was applied to investigate the level lifetimes in Mg-30,Mg-31,Mg-32. Levels in Mg have been populated in beta and beta-delayed neutron emission of Na, at the ISOLDE facility. From the gamma gamma coincidences a number of new states have been identified and new level schemes were constructed for 30 31,32 Mg. The following preliminary half lives have been d
International standardization and coordination of the nomenclature of variants of hepatitis C virus (HCV) is increasingly needed as more is discovered about the scale of HCV-related liver disease and important biological and antigenic differences that exist between variants. A group of scientists expert in the field of HCV genetic variability, and those involved in development of HCV sequence data
Fossilbaserad elproduktion i Sverige fasas ut allt mer och ersätts med förnybara energikällor. Omställningen till ett mer förnybart energisystem fortgår redan nu eftersom intermittenta förnybara energikällor, såsom vindkraft, driftsätts varje år. Denna omvandling innebär utmaningar för elnätet eftersom tillgång och efterfrågan inte alltid sammanfaller. Flexibilitetsåtgärder kan mildra dessa effekt
Factors limiting fat cell expandability remain scarcely explored, and comprehensive functional comparisons of adipose depots in humans are limited. In the present study, we collected visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) paired-samples from 22 patients with obesity undergoing elective Roux-en-Y gastric bypass surgery. Whole tissue samples were used to determine adipoc
For some bird species the outermost part of the wings, the feathers can separate from each other and the wing, in such cases each feather must act as an independent aerodynamic unit. In addition to regular function of flight feathers such as colouring and overall aerodynamic and structural capabilities, these separated feathers must withstand the aeroelastic demands on their own using the complex For some bird species the outermost part of the wings, the feathers can separate from each other and the wing, in such cases each feather must act as an independent aerodynamic unit.

High-spin states in Nb-85 were studied using the GAMMASPHERE Ge detector array and the MICROBALL charged-particle detector system. Three gamma-ray cascades with collective rotational characteristics were observed. One of the bands exhibits a forking at the top, most likely reflecting the termination of one branch into a favoured non-collective, near spherical state. The data are interpreted in ter
We have previously observed that pyridoxine treatment reduced plasma total cholesterol (TC) and low-density lipoprotein (LDL) cholesterol concentrations and increased antithrombin III (AT III) activity in atherosclerotic patients with subnormal plasma pyridoxal 5-phosphate (PLP) levels. In order to confirm these results, we selected 17 males with low plasma PLP levels from a group of 122 80-year-o
The evidence for macroscopic life during the Palaeoproterozoic era (2.5-1.6 Gyr ago) is controversial. Except for the nearly 2-Gyr-old coil-shaped fossil Grypania spiralis, which may have been eukaryotic, evidence for morphological and taxonomic biodiversification of macroorganisms only occurs towards the beginning of the Mesoproterozoic era (1.6-1.0 Gyr). Here we report the discovery of centimetr
Background A genetic component of early-onset lung cancer has been suggested. The role of metabolic gene polymorphisms has never been studied in young lung cancer cases. Phase 1 and Phase 2 gene polymorphisms are involved in tobacco carcinogens' metabolism and therefore in lung cancer risk. Methods The effect of metabolic gene polymorphisms on lung cancer at young ages was studied by pooling data
BACKGROUND: With substantial progress made toward polio eradication, developing the appropriate strategy for discontinuing global oral poliovirus vaccine (OPV) after global eradication becomes increasingly important. At issue is the theoretical risk of independent circulation of potentially virulent OPV-derived strains. Because Cuba uses OPV only in mass campaigns, it represents an ideal site to a
En signal är en fysisk kvantitet som varierar med någon oberoende variabel, t.ex. tid eller rum, som förmedlar information. En signal vars statistiska egenskaper är konstant i tid kallas stationär, medan signaler vars egenskaper varierar med tiden kallas icke-stationära, vilket är de vanligaste i naturen. Denna avhandling fokuserar på statistiska metoder för icke-stationära signaler. De applikatioThis thesis focuses on statistical methods for non-stationary signals. The methods considered or developed address problems of stochastic modeling, inference, spectral analysis, time-frequency analysis, and deep learning for classification. In all the contributions, an example of a biomedical application of the proposed method is provided, either to electroencephalography (EEG) data or to Heart Ra
Neutron macromolecular crystallography (NMX) is a complementary technique to X-ray crystallography leveraging neutron scattering properties of the hydrogen isotope deuterium (2H). Production of deuterium labelled molecules together with large crystal requirements for neutron crystallography are few of several bottlenecks limiting implementation of this technique for a wider range of proteins.

OBJECTIVES: Primary graft dysfunction is a severe form of acute lung injury and a major cause of early morbidity and mortality encountered after lung transplant.We used a customized PExA 2.0 instrument (PExA, Gothenburg, Sweden) to measure particle flow in exhaled air during mechanical ventilation in the intensive care unit. Our objective was to discover whether patients who developed primary graf
BACKGROUND: We have previously developed (11)C-erlotinib as a new positron emission tomography (PET) tracer and shown that it accumulates in epidermal growth factor receptor (EGFR)-positive lung cancer xenografts in mice. Here, we present a study in patients with non-small cell lung cancer (NSCLC) investigating the feasibility of (11)C-erlotinib PET as a potential method for the identification of
While tau pathology is closely associated with neurodegeneration in Alzheimer's disease (AD), our prior work using multi-modality imaging revealed that mismatch between tau (T) and neurodegeneration (N) may reflect contributions from non-AD processes. The medial temporal lobe (MTL), an early site of AD pathology, is also a common target of co-pathologies such as limbic-predominant age-related TDP-
