Association of common variants in NPPA and NPPB with circulating natriuretic peptides and blood pressure

We examined the association of common variants at the NPPA-NPPB locus with circulating concentrations of the natriuretic peptides, which have blood pressure-lowering properties. We genotyped SNPs at the NPPA-NPPB locus in 14,743 individuals of European ancestry, and identified associations of plasma atrial natriuretic peptide with rs5068 (P = 8 x 10(-70)), rs198358 (P = 8 x 10(-30)) and rs632793 (

Search for a heavy neutral particle decaying into an electron and a muon using 1 fb(-1) of ATLAS data

A search is presented for a high mass neutral particle that decays directly to the e(+/-) mu(-/+) final state. The data sample was recorded by the ATLAS detector in root s = 7 TeV pp collisions at the LHC from March to June 2011 and corresponds to an integrated luminosity of 1.07 fb(-1). The data are found to be consistent with the Standard Model background. The high e(+/-) mu(-/+) mass region is

Molecular Exchange between Intra- and Extracellular Compartments in a Cell Suspension

In this work we present a PFG-SE technique to obtain the a characteristic time for molecular exchange between domains with slow diffusion and domains with fast diffusion. The method has been demonstrated by measuring the change of exchange time with temperature for a sedimented yeast cell suspension. Compared to previous methods the new protocol is more sensitive to exchange and as few as 40 data

Extended analysis of the TiI spectrum: 3d-4f, 4d-4f and 4f-5g transitions

Titanium spectra recorded in the infrared wavelength region with a Fourier Transform Spectrometer have been analysed, and 572 lines have been identified as transitions of the types 3d-4f, 4d-4f and 4-5g. 11 lines in the UV region around 2400 angstrom have been identified as belonging to the 3d(3)4s a(5)F-3d(2)4s(F-4)4f transition array. 113 levels of the 3d(2)4s(F-4)4f, 3d(3)(F-4)4f and 3d(2)4s(F-

Displacement of the occluding loop by the parasite protein, chagasin, results in efficient inhibition of human cathepsin

Cathepsin B is a papain-like cysteine protease showing both endo- and exopeptidase activity, the latter due to a unique occluding loop that restricts access to the active site cleft. To clarify the mode by which natural protein inhibitors manage to overcome this obstacle, we have analyzed the structure and function of cathepsin B in complexes with the Trypanosoma cruzi inhibitor, chagasin. Kinetic

Lupine-induced anaphylaxis

BACKGROUND: Legumes are one of the most common foods causing allergic reactions in children and adults. Cross-reacting antibodies are frequently demonstrated in this family but the real clinical cross-reactivity is uncommon. OBJECTIVE: To report a case of lupine-induced anaphylaxis and to elucidate in vivo and in vitro cross-reactivity with some legumes. METHODS: Skin prick test (SPT) with some le

MHC genes and oxidative stress in sticklebacks: an immuno-ecological approach

Individual variation in the susceptibility to infection may result from the varying ability of hosts to specifically recognize different parasite strains. Alternatively, there could be individual host differences in fitness costs of immune defence. Although, these two explanations are not mutually exclusive, they have so far been treated in separate experimental approaches. To analyse potential re

Diagnosis and follow-up of neuroblastoma by means of iodine-123 metaiodobenzylguanidine scintigraphy and bone scan, and the influence of histology

The purpose of this work was to compare technetium-99m-diphosphono-propanedicarboxylate (DPD) and iodine-123-metaiodobenzylguanidine (MIBG) scans in the diagnosis and follow-up of neuroblastoma, and to study the role of histological differentiation in the uptake of MIBG. The uptake of MIBG and of DPD were studied retrospectively in 27 patients with neuroblastoma (primary, residual and recurrent tu

Advanced oxidation of refractory organics in leachate--potential methods and evaluation of biodegradability of the remaining substrate.

An assessment of potential methods suitable for degradation and/or reduction of refractory organics was performed on landfill leachate from SYSAV AB, Malmö, Sweden. Pretreatment of the leachate was performed in a sequence batch reactor designed for nitrification in activated sludge. Oxidation of the leachate was then O3, O3/pH adjustment (pH 9 and 10), H2O2, O3/H2O2 and performic acid in lab-scale

Circulating monocytes from healthy individuals and COPD patients.

Background: Chronic obstructive pulmonary disease (COPD) is characterized by incompletely reversible airflow obstruction associated with inflammation in which monocytes/macrophages are the predominant inflammatory cells. The only known genetic factor related to COPD is inherited PiZZ deficiency of alpha1-antitrypsin (AAT), an inhibitor of serine proteases. Methods: We investigated the basal and LP

Evolution and maintenance of pollen-colour dimorphisms in Nigella degenii: habitat-correlated variation and morph-by-environment interactions

Dimorphism in pollen colour is rare among flowering plants, but occurs in two geographically and morphologically distinct subspecies of Nigella degenii (Ranunculaceae). We evaluated the role of genotype-by-environment interactions in the maintenance of two pollen morphs within each of these subspecies. Morph frequencies in a number of populations were related to current habitat conditions, and an

LCA queries in directed acyclic graphs

We present two methods for finding a lowest common ancestor (LCA) for each pair of vertices of a directed acyclic graph (dag) on n vertices and m edges. The first method is surprisingly natural and solves the all-pairs LCA problem for the input dag on n vertices and m edges in time O(nm). As a corollary, we obtain an O(n(2))-time algorithm for finding genealogical distances considerably improving

Feasibility of a branched stent-graft in common iliac artery aneurysms.

Purpose: To evaluate the short-term feasibility, efficacy, and safety of a modular bifurcated stent-graft with an internal iliac artery (IIA) side branch for endovascular repair of aortoiliac aneurysms. Methods: Between 2002 and 2005, 10 male patients (median age 75 years, range 59–83) were treated with a bifurcated stent-graft that included a unilateral side branch for the IIA. The median diamet

Early cerebral metabolic and electrophysiological recovery during controlled hypoxemic resuscitation in piglets

We tested the hypothesis that controlled hypoxemic resuscitation improves early cerebral metabolic and electrophysiological recovery in hypoxic newborn piglets. Severely hypoxic anesthetized piglets were randomly divided into three resuscitation groups: hypoxemic, 21% O2, and 100% O2 groups (8 in each group). The hypoxemic group was mechanically ventilated with 12-18% O2 adjusted to achieve a cere

Simple approach to polyampholytes based on chain polarizabilities

The polarizabilities of polyampholytes have been calculated in Monte Carlo simulations. For chains with random charge topologies, the polarizability increases with the chain length and the chain flexibility. For block copolymers, the polarizability initially increases with the block size to a maximum and then decreases. The polarizability is used to characterize the interaction between polyampholy

Transvascular protein transport in mice lacking endothelial caveolae.

Caveolae are Omega-shaped vesicular structures postulated to play a role in transvascular protein transport. Studies on mice lacking endothelial caveolae, caveolin-1 knockout (Cav-1-KO) mice, indicate increased macromolecular transport rates. This was postulated to be due to the appearance of an alternative pathway. The present study tested whether an alternative pathway had appeared in Cav-1-KO m

The human P-k histo-blood group antigen provides protection against HIV-1 infection

Several human histo-blood groups are glycosphingolipids, including P/P1/P-k. Glycosphingolipids are implicated in HIV-host-cell-fusion and some bind to HIV-gp120 in vitro. Based on our previous studies on Fabry disease, where P-k accumulates and reduces infection, and a soluble P-k analog that inhibits infection, we investigated cell surface-expressed P-k in HIV infection. HIV-1 infection of perip

Absorption and lipoprotein transport of sphingomyelin

Dietary sphingomyelin (SM) is hydrolyzed by intestinal alkaline sphingomyelinase and neutral ceramidase to sphingosine, which is absorbed and converted to palmitic acid and acylated into chylomicron triglycerides (TGs). SM digestion is slow and is affected by luminal factors such as bile salt, cholesterol, and other lipids. In the gut, SM and its metabolites may influence TG hydrolysis, cholestero

Arthrodesis of the ankle secondary to replacement

One hundred total ankle arthroplasties were performed in our department between 1974 and 1994, and of these, 21 have been reoperated on with arthrodesis due to septic or nonseptic failures after 6 months to 15 years (median 40 months). Immobilization using a Hoffman external fixator was the dominating method. The total ankles were of six different designs. Sixteen of the 21 patients suffered from
