Background In mild asthma exercise-induced bronchoconstriction (EIB) is usually treated with inhaled short-acting beta(2) agonists (SABAs) on demand. Objective The hypothesis was that a combination of budesonide and formoterol on demand diminishes EIB equally to regular inhalation of budesonide and is more effective than terbutaline inhaled on demand. Methods Sixty-six patients with asthma (>12 ye

We study the Zeeman spin splitting in a quantum point contact (QPC) etched into an InGaAs/InP heterostructure for three orthogonal magnetic field orientations with respect to the QPC. For the two in-plane orientations we observe an isotropic Zeeman spin splitting, which becomes stronger as the system is made more one dimensional. The Lande g factor is enhanced by up to a factor of two compared to

Purpose: An increasing incidence and improved prognosis of kidney cancer have led to concern about second primary malignancies. The study of multiple primary malignancies is also important since the association of certain malignancies may guide the search for germline alterations and environmental risk factors. We evaluated bidirectional associations between renal cell carcinoma and other primary

BACKGROUND: Knowledge regarding characteristics and transmission of Neisseria gonorrhoeae, Chlamydia trachomatis and Mycoplasma genitalium and antibiotic resistance in N gonorrhoeae in Guinea-Bissau, West Africa, is entirely lacking. OBJECTIVES: To characterise N gonorrhoeae, C trachomatis and M genitalium samples from Guinea-Bissau and to define bacterial populations, possible transmission chains

Background: Improving maternal and reproductive health still remains a major challenge in most low-income countries especially in sub-Saharan Africa. The growing inequality in access to maternal health interventions is an issue of great concern. In Ghana, inadequate attention has been given to the inequality gap that exists amongst women when accessing antenatal care during pregnancy and skilled a

Background: Previous studies of the association between gestational age or birth weight and allergic rhinitis in later life have had various limitations, including the inability to estimate risk among subjects born extremely preterm or to examine specific contributions of gestational age and fetal growth. Objective: We sought to determine whether gestational age at birth independent of fetal growt

Accidental falls in the elderly are a major health problem, despite extensive research on risk factors and prevention. Only a limited number of multifactorial, long-term prospective studies have been performed on risk factors for falls in the general elderly population. The aim of this study was to identify risk factors predicting falls in a general elderly population after three and six years, us

Hairdressing work is classified as carcinogenic based on excess risk for bladder cancer. We aimed at evaluating if current hairdressers are exposed to established/suspected bladder carcinogens (aromatic amines) and indicate possible sources of exposure.

We present a framework based on object orientation with novel principles for how to store, analyze and integrate electrophysiological data. These principles are: (I) Using a Decorator pattern for storing analysis data in an object model, (II) using a Core Classes data structure for integration through mediation in a service bus architecture, and (III) choosing the single unit as the finest structu

We report conductance and supercurrent of InAs nano wires coupled to Al-superconducting electrodes with short channel lengths and good Ohmic contacts. The nanowires are suspended 15 nm above a local gate electrode. The charge density in the nanowires can be controlled by a small change in the gate voltage. For large negative gate voltages, the number of conducting channels is reduced gradually, an

Kaposi sarcoma (KS) is a locally aggressive endothelial tumour that is classified into 4 clinico-epidemiological forms: classic KS affecting lower limbs in elderly Mediterranean or East European men; endemic KS occurring in extremities among Equatorial African middle-aged men and children; iatrogenic KS involving lower limbs in immunosuppressive patients; and AIDS-associated (epidemic) KS observed

The ability to tune the photon absorptance spectrum is an attracting way of tailoring the response of devices like photodetectors and solar cells. Here, we measure the reflectance spectra of InP substrates patterned with arrays of vertically standing InP nanowires. Using the reflectance spectra, we calculate and analyze the corresponding absorptance spectra of the nanowires. We show that we can tu

Background: To examine the association of education with body mass index (BMI) and waist circumference (WC) in the European Prospective Investigation into Cancer and Nutrition (EPIC). Method: This study included 141,230 male and 336,637 female EPIC-participants, who were recruited between 1992 and 2000. Education, which was assessed by questionnaire, was classified into four categories; BMI and WC

We present RF characterization of vertical gateall- around InAs nanowire MOSFETs integrated on Si substrates with peak f(t) = 142 GHz and f(max) = 155 GHz, representing the record for vertical nanowire transistors. The devices has an L-g approximate to 150 nm with a g(m)=700 mS/mm for a nanowire diameter of 38 nm and an EOT = 1.4 nm. The high values of f(t) is achieved through electron beam lithog

Carbon paste electrodes modified with a phenoxazine derivative, Meldola blue, and a phenothiazine derivative, methylene green, both strongly adsorbed on a synthetic zeolite were investigated using either glassy carbon powder (Sigradur K, SK) or single-walled carbon nanotubes (SWCNT) as conductive electrode material. In the case of SWCNT based electrodes, the formal potential of both mediators was

Estrogen receptor (ER)-negative breast cancer shows a higher incidence in women of African ancestry compared to women of European ancestry. In search of common risk alleles for ER-negative breast cancer, we combined genome-wide association study (GWAS) data from women of African ancestry (1,004 ER-negative cases and 2,745 controls) and European ancestry (1,718 ER-negative cases and 3,670 controls)

Background. There are large geographic differences in breast cancer risk but whether survival differs between low- and high-risk groups is less well-established. As the survival of cancer depends on the level of healthcare and awareness of disease risks, subtle differences in cancer biology cannot be revealed in international comparisons. Instead, comparison of diverse immigrant groups in a countr

Background: Patients with many types of autoimmune diseases (AIDs) are at an increased risk of cancer, which may depend on underlying dysregulation of the immune system or treatment. We systematically analyzed myeloma risk and survival in patients diagnosed with 33 different AIDs. Methods: Data on patients with AIDs were retrieved from the Swedish Hospital Discharge Register and were linked to mye

ObjectiveTo examine the frequency, characteristics, and outcome of mood disorders, as well as clinical and autoantibody associations, in a multiethnic/racial, prospective inception cohort of patients with systemic lupus erythematosus (SLE). MethodsPatients were assessed annually for mood disorders (4 types, according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition) and
