Skipping the Baltic: the emergence of a dichotomy of alternative spring migration strategies in Russian barnacle geese

Since the early 1990s, an increasing proportion of barnacle geese, Branta leucopsis, bound for breeding sites in the Russian Arctic delay their departure from the wintering quarters in the Wadden Sea by 4 weeks. These late-migrating geese skip spring stopover sites in the Baltic traditionally used by the entire population. Individual geese from an arctic colony tracked by satellite or light-level

Acute pancreatitis in Soweto, South Africa: Relationship between trypsinogen load, trypsinogen activation, and fibrinolysis

Objective: It is not known why acute pancreatitis in Soweto, South Africa, pursues an aggressive course. We sought clues from circulating trypsinogen load at admission as marker of initial acinar injury, trypsinogen activation using the carboxypeptidase B activation peptide as surrogate, proteinase inhibitors, the coagulation-fibrinolysis axis, indicators of inflammation, oxidative stress markers,

Does It Really Matter Where You Live? A Panel Data Multilevel Analysis of Swedish Municipality Level Social Capital on Individual Health-Related Quality of Life

We test whether individual health status is related to area-level social capital measured by rates of voting participation in municipal political elections, controlling for personal characteristics, where health status is measured by mapping responses to interview survey questions into the generic health-related quality of life measure (HRQoL) the EQ-5D in order to derive the health state scores.

Inhibition of propylene oxidation to acrylic acid by amorphous overlayers on MoV(Nb)TeO based M2 catalysts

One of the most effective catalysts for the selective oxidation of propane to acrylic acid (AA) and ammoxidation to acrylonitrile (AN) is the MoV(Nb,Ta)(Te,Sb)O system, comprised of two phases, with M1 the major catalyst and M2 the co-catalyst in symbiosis with M1, converting intermediately formed propylene to the respective desired end products. An improvement in either phase should enhance the o

Abdominal manifestations of non-Hodgkin's lymphomas

25 children (18 boys and 7 girls) were treated for non-Hodgkin's lymphomas (NHL) during 1982-1990. The age at diagnosis was 2-15 years. Five of the 25 children died. Of the 25 children 6 patients had the diagnosis of intraabdominal NHL. The presenting abdominal symptoms for these 6 patients were abdominal pain in 4 cases, nausea 3, abdominal distention 2, icterus 1 and diarrhoea 1. Four of the 6 p

Levels of apolipoprotein M are not associated with the risk of coronary heart disease in two independent case-control studies

Apolipoprotein M (apoM), a 25 kDa plasma protein belonging to the lipocalin protein family, is predominantly associated with HDL. Studies in mice have suggested apoM to be important for the formation of pre-beta-HDL and to increase cholesterol efflux from macrophage foam cells. Overexpression of human apoM in LDL receptor-deficient mice reduced the atherogenic effect of a cholesterol-rich diet. Th

Chlorhexidine for prevention of neonatal colonization with group B streptococci. V. Chlorhexidine concentrations in blood following vaginal washing during delivery

Chlorhexidine 2 g/l was applied to the vagina of 96 women during delivery, whereas 28 served as controls. Both groups were given a shower using a chlorhexidine soap, and outer washing of the outer anogenital tract was also performed in all patients using chlorhexidine 2 g/l. Using a gas chromatographic method with a detection limit of 10 ng chlorhexidine per ml blood, 10-83 ng/ml was demonstrated

No evidence for genomic imprinting of the human BCR gene

Chronic myeloid leukemias and 5% to 20% of acute lymphoid leukemias are characterized by the Philadelphia chromosome, a reciprocal chromosomal translocation, t(9;22)(q34;q11), generating BCR-ABL and ABL-BCR fusion genes. Cytogenetic studies have recently shown a preferential involvement of the paternally derived chromosome 9 and the maternally derived chromosome 22 in this translocation, indicatin

Visual Position Tracking using Dual Quaternions with Hand-Eye Motion Constraints

In this paper a method for contour-based rigid body tracking with simultaneouscamera calibration is developed. The method works for a singleeye-in-hand camera with unknown hand-eye transformation,viewing a stationary object with unknown position. The method usesdual quaternions to express the relationship between the camera- andend-effector screws. It is shown how using the measured motion of ther

Advanced optics in a jellyfish eye

Cubozoans, or box jellyfish, differ from all other cnidarians by an active fish-like behaviour and an elaborate sensory apparatus(1,2). Each of the four sides of the animal carries a conspicuous sensory club ( the rhopalium), which has evolved into a bizarre cluster of different eyes(3). Two of the eyes on each rhopalium have long been known to resemble eyes of higher animals, but the function and

Do corridors promote dispersal in grassland butterflies and other insects?

Ecological corridors are frequently suggested to increase connectivity in fragmented landscapes even though the empirical evidence for this is still limited. Here, we studied whether corridors, in the form of linear grass strips promote the dispersal of three grassland butterflies, using mark-recapture technique in an agricultural landscape in southern Sweden. We found no effects of the presence o

Cardiac Structure and Function Before and After Parathyroidectomy in Patients With Asymptomatic Primary Hyperparathyroidism

Background: Primary hyperparathyroidism (PHPT) is associated with cardiac disease and increased risk of all-cause and cardiovascular mortality. We investigated cardiac structural and functional parameters before and after successful parathyroidectomy in asymptomatic PHPT patients. Methods and Results: Forty-nine PHPT patients (age: 62.9 +/- 11 years, 5 men) and 48 healthy control subjects, matched

Plasma lipolytic activity after subcutaneous administration of heparin and a low molecular weight heparin fragment

The effect of heparin and a low molecular weight heparin fragment (LMWH, mean molecular weight 4000-6000) on plasma anticoagulation and lipolysis was studied in eight healthy men. The activities of antifactor Xa (antiFXa), lipoprotein lipase (LPL), hepatic lipase (HL) and plasma levels of free fatty acids (FFA) were analysed after the injection of 5000 antiFXa units of heparin or LMWH subcutaneous

Stress calculations on multiply connected domains

The outstanding problem of finding a simple Muskhelishvili-type integral equation for stress problems on multiply connected domains is solved. Complex potentials are represented in a way which allows, for the incorporation of cracks and inclusions. Several numerical examples demonstrate the generality and extreme stablity of the approach. The stress field is resolved with a relative error of less

The Stenshuvud and Taghusa granitoids: new representatives of Mesoproterozoic magmatism in southern Sweden

New sites of Mesoproterozoic granitoid magmatism in southern Sweden have been discovered by recent fieldwork and U-P zircon age determination. In the area around Stenshuvud, in eastern Skane, granitic melts were intruded into country-rock gneisses of unknown age at c. 1450 Ma. The 1458 6 Ma Stenshuvud intrusion is composed of several rock varieties including quartz monzonite, tonalite, monzogranit

Tolerability, efficacy and pharmacokinetics of bicalutamide 300 mg, 450 mg or 600 mg as monotherapy for patients with locally advanced or metastatic prostate cancer, compared with castration

OBJECTIVE To evaluate the pharmacokinetics, tolerability and effect on endocrinology of bicalutamide given as once-daily monotherapy at doses of > 150 mg to patients with locally advanced (MO) or metastatic (M1) prostate cancer, with efficacy as a secondary endpoint. PATIENTS AND METHODS Patients were initially enrolled to receive bicalutamide 300 mg in a non-randomized phase, after which further
