Sera from patients with sexually acquired reactive arthritis (SARA) with antibodies reacting with C. trachomatis and C. pneumoniae (group 1; n = 20) and also with C. psittaci (group 2; n = 19) were analyzed for antibody specificity. Sera from group 2 reacted significantly more often with C. trachomatis serotype E, H and K and had higher antibody titers to serotype E, as tested by microimmunofluore
We consider classes G(s)([0, 1]) of subsets of [0, 1], originally introduced by Falconer, that are closed under countable intersections, and such that every set in the class has Hausdorff dimension at least s. We provide a Frostman-type lemma to determine if a limsup set is in such a class. Suppose that E = lim supE(n) subset of [0, 1], and that mu(n) are probability measures with support in E-n.
A search is reported for Higgs boson decay to mu(+)mu(-) using data with an integrated luminosity of 24.8 fb(-1) collected with the ATLAS detector in pp collisions at root s = 7 and 8 TeV at the CERN Large Hadron Collider. The observed dimuon invariant mass distribution is consistent with the Standard Model background-only hypothesis in the 120-150 GeV search range. For a Higgs boson with a mass o
Popular Abstract in Swedish Människans utveckling och fysiologiska anpassning till upprätt kroppställning är beroende av en rad blodtrycksreglerande mekanismer. Vid ortostatisk hypotension sjunker blodtrycket i samband med uppresning från liggande till stående. Detta beror på en sviktande cirkulationsanpassning så att organismen inte förmår att upprätthålla ett tillräckligt högt blodtryck. SymtomeOrthostatic hypotension (OH) is believed to be an important cause of cerebral hypoperfusion, leading to chronic fatigue, blurred vision, unsteadiness, dizziness and sometimes syncope. It may also result in episodes of confusion, falls and fractures. The coupling between OH and organic dementia is not clear. Our findings in a large group of patients with Alzheimer's disease, vascular- and frontotem
Engineering design problems are most frequently charac-terized by constraints that make them hard to solve and time-consuming. When evolutionary algorithms are used to solve these problems, constraints are often handled with the generic weighted sum method or with techniques specific to the prob-lem at hand. Most commonly, all constraints are evaluated at each generation, and it is also necessary
Popular Abstract in Swedish I Sverige insjuknar årligen drygt 6000 kvinnor i bröstcancer. Antalet nyinsjuknade kvinnor i sjukdomen stiger något för varje år samtidigt som dödligheten minskar. En av orsaken till den minskade dödligheten är modern medicinsk behandling som idag kompletterar den kirurgiska behandlingen. Sjukdomsförloppet vid bröstcancer är mycket varierande beroende på tumörens utbredBackground: Treatment of primary breast cancer is individualised and adjuvant systemic treatment is delivered to most patients after surgery. Oestrogen receptor (ER) status and progesterone receptor status (PR) can define patients who would benefit from adjuvant endocrine therapy with tamoxifen (TAM) alone or as chemo-endocrine therapy. In spite of adjuvant treatment with TAM, some patients with h
Popular Abstract in Swedish Hjärt-kärlsjukdomar är en ledande orsak av sjuklighet och dödlighet. Med hjälp av dagens moderna ultraljudsteknik är det möjligt att påvisa även begynnande, mycket diskreta kärlförändringar. En tidig upptäckt av dessa kan bli av betydelse för individens framtida hälsa. I ett antal studier har vi med hjälp av ultraljud undersökt kärlens styvhet och förmåga att vidgas (enCardiovascular disease (CVD) is one of the leading causes of mortality and morbidity. Early recognition of vascular changes, both structural and functional, may help to identify individuals at risk for CVD. Using modern ultrasound techniques – the echo-tracking technique for assessment of stiffness in large arteries and flow-mediated dilatation of the brachial artery as an indicator of endothelial
The authors report on the fabrication of subsurfaced 100-600 nm wide nanochannels in fused silica with top slit openings in the size range of 5-10 nm. Such nanochannels can be used in combination with a nanofluidics system to guide molecular motors and quickly switch the chemical environment inside the nanochannels through diffusion via the top slits. To realize nanochannel top slits in this size
Let mu be a Gibbs measure of the doubling map T of the circle. For a mu-generic point x and a given sequence {r(n)} subset of R+, consider the intervals (T-n x - r(n) (mod 1), T-n x + r(n) (mod 1)). In analogy to the classical Dvoretzky covering of the circle, we study the covering properties of this sequence of intervals. This study is closely related to the local entropy function of the Gibbs me
The recent years of development in mobile computing as powerful handheld computers and high-speed wireless networks creates opportunities for new user-groups in the mobile workforce to take advantage of mobile technologies. User-groups may be more or less geographical distributed and as a consequence more or less marooned when it comes to obtaining IT/IS support and this increases the complexity o
Background: Individuals with Williams syndrome, a rare genetic disorder, are characterized by specific medical, cognitive, and behavioral phenotypes and often have high anxiety levels as well as phobia. Studies of the psychiatric phenotype in adults affected by Williams syndrome or literature on the management of their mental pathologies are lacking. Method: In this article, we report the neuropsy
We have studied the effects of cholesterol and steroid-based antibiotic fusidic acid (FA) on the behavior of lipid bilayers using a variety of experimental techniques together with atomic-scale molecular dynamics simulations. Capillary electrophoretic measurements showed that FA was incorporated into fluid 1-palmitoyl-2-oleoyl-sn-glycero-3-phosphocholine membranes. Differential scanning calorimetr
Analysis of high-frequency QRS components (HF-QRS) might provide an additional method when diagnosing various heart diseases, for example ischemic heart disease (HID). This study compares HF-QRS in normal Subjects to those in patients with HID, and also analyzes HF-QRS considering gender and age. A total of 63 normal subjects and 64 patients with IHD were included. Signal-averaged electrocardiogra
Allergic rhinitis is a predisposing factor for developing clinical asthma. Moreover, allergic rhinitis is often associated with bronchial hyperresponsiveness (BHR). We hypothesise that patients with asthma have more small airway involvement than those with allergic rhinitis and BHR alone. The aim of this study was to assess peripheral and proximal NO concentration in rhinitic subjects, and to corr
Aims: Many lymphoma patients have both macroscopic tumors and single-cell manifestations of their disease. Treatment efficacy could, therefore, depend on the radionuclide used. The aim of this study was to investigate dosimetry at a cellular level for three isotopes of radioiodine. Methods: Cells were assumed to be spherical with radii of 6.35, 7.7, and 9.05 mu m corresponding to the dimensions of
