Climate change is occurring more rapidly in the Arctic than elsewhere, and is predicted to have a large impact on biodiversity, since entire cold-adapted ecosystems are likely to disappear. Here, we highlight changes in the insect species richness and community composition of wild bees, butterflies and moths over 60 years in an area situated above the tree limit (Padjelanta National Park) in north
Background The hereditary non-polyposis colorectal cancer (HNPCC) subset of tumours can broadly be divided into tumours caused by an underlying mismatch-repair gene mutation, referred to as Lynch syndrome, and those that develop in families with similar patterns of heredity but without disease-predisposing germline mismatch repair mutations, referred to as familial colorectal cancer type X (FCCTX)
This paper characterizes strategy-proof social choice functions (SCFs), the outcome of which are multiple public goods. Feasible alternatives belong to subsets of a product set $${A_{1} imes cdots imes A_{m}}$$ . The SCFs are not necessarily “onto”, but the weaker requirement, that every element in each category of public goods A k is attained at some preference profile, is imposed instead. Admis
Background: Meniscus extrusion or hypertrophy may occur in knee osteoarthritis (OA). However, currently no data are available on the position and size of the meniscus in asymptomatic men and women with normal meniscus integrity. Methods: Three-dimensional coronal DESSwe MRIs were used to segment and quantitatively measure the size and position of the medial and lateral menisci, and their correlati
Bra inomhusklimat och effektiv energianvändning är av yttersta vikt när nya hus ska byggas. Ny teknik har fått ner behovet av energi för uppvärming till ungefär hälften sedan 70-talet. Men elförbrukningen har ökat kraftigt. Här presenterar författarna en systematisk helhetssyn att både spara energi och åstadkomma ett behagligt inneklimat när nya hus utformas eller gamla renoveras. Byggteknik och
During embryonic development and adult life a wide range of cell behaviors such as differentiation, proliferation and migration are in effect to maintain tissue integrity and function. An integral part of these dynamic processes is the interplay between the cells and their environment, i.e. the extracellular space. Complex polysaccharides, such as dermatan sulfate play a key role in these processe
Multiple system atrophy (MSA) is a fatal adult-onset neurodegenerative disease characterized by α-synuclein (α-syn) positive oligodendroglial cytoplasmic inclusions. The latter are associated with a neuronal multisystem neurodegeneration targeting central autonomic, olivopontocerebellar and striatonigral pathways, however the underlying mechanisms of neuronal cell death are poorly understood. Prev
Background: With an increased life expectancy for the general population as well as for those ageing with chronic diseases, there are major challenges to the affected individuals and their families, but also to health care and societal planning. Most important, an increasing proportion of older people remain living in their ordinary homes despite health decline and disability. However, little is k
The influence of lithium (Li) exposures on monolayer graphene grown on the silicon-terminated SiC(0001) surface is investigated using low-energy electron microscopy, photoelectron spectroscopy, and micro-low-energy electron diffraction. After Li deposition, islands or Li droplets are observed on the surface, and are found to coalesce together with time. Formation of a dipole layer at the interface
Abstract in Undetermined The aim of this study was to compare the differences between the level of whole quality of life and its subscales after receiving two common treatment of breast cancer in women with early stage of breast cancer. A double-blinded cohort study was done in 100 breast cancer patients with node positive that used fluorouracil, doxorubicin, cyclophosphamide (FAC) and docetaxel,

Since its establishment, the Android applications market has been infected by a proliferation of malicious applications. Recent studies show that rogue developers are injecting malware into legitimate market applications which are then installed on open source sites for consumer uptake. Often, applications are infected several times. In this paper, we investigate the behavior of malicious Android
Popular Abstract in English My PhD thesis has focused on increasing the understanding of the osteoclasts, the cells responsible for degradation of bone, by studying the rare hereditary disease autosomal recessive osteopetrosis (ARO). ARO is present already at birth and is caused by mutations affecting the osteoclasts ability to degrade bone. Non-functional osteoclasts lead to dramatic increases inThis thesis focuses on developing and characterizing novel models for studying osteoclasts with an emphasis on how mutations abolishing osteoclastic acidification affect osteoclast signaling and bone remodeling, as well as how to treat patients bearing these rare mutations. Bone remodeling is under normal circumstances a tightly balanced process where resorption of bone by osteoclasts is followed
Highly resolved vibrational spectra for the Zn-complexes of several meso-substituted tetraarylporphyrins were recorded by fluorescence line narrowing (FLN) method at liquid helium temperature. The frequencies of the vibronic lines of the Zn-5,10,15,20-tetraphenylporphyrin (ZnTPP), the Zn-5,10,15,20-tetramesitylporphyrin (ZnTMesP) and four meso-indolocarbazolyl-substituted porphyrin compounds in th
Gaucher disease type 1 (GD type 1) and Diamond-Blackfan anemia (DBA) are rare genetic disorders affecting the hematopoietic system and routinely treated by administration of drugs with variable clinical efficacy. Though effective in alleviating disease symptoms in large cohorts of patients, these treatment options have the major drawback of being non-curative. Currently, bone marrow transplantatio
Bacteria appeared on the Earth millions years before us and human evolution was triggered by the constant presence of pathogenic and symbiotic microorganisms in our surroundings. Interplay occurred between higher organism and microbial consortia residing in the host organs and on the epithelial surfaces; another natural space of bacteria human interaction is the indoor environment where we spend t
Many cyber-physical systems comprise several control applications sharing communication and computation resources. The design of such systems requires special attention due to the complex timing behavior that can lead to poor control quality or even instability. The two main requirements of control applications are: (1) robustness and, in particular, stability and (2) high control quality. Althoug
Halisaurine mosasaurs are poorly known, represented by a small number of specimens from the Santonian-Maastrichtian (similar to 86 Ma - similar to 66 Ma), but enjoyed broad palaeobiogeographic distribution during that time. They are important for understanding mosasaur evolution because certain aspects of their morphology retain the relatively plesiomorphic or minimally modified squamate condition
