We present a protocol for a facile orientation specific deposition of plate-like mesoporous SBA-15 silica particles onto a surface (mesopores oriented normal to surface). A drop of an aqueous dispersion of particles is placed on the surface and water vaporizes under controlled relative humidity. Three requirements are essential for uniform coverage: particle dispersion should not contain aggregate

Zinc oxide nanorod-extended gate field effect transistor (MOSFET) is demonstrated for the detection of calcium (Ca2+) ions. ZnO nanorods were grown on the surface of a silver wire to produce an electrochemical nanosensor for selectively detecting Ca2+. The electrochemical response from the interaction between the ZnO nanorods and Ca2+ in an aqueous solution is coupled directly to the gate of a fie

The enzyme myeloperoxidase shows several unusual properties compared to other peroxidases, e.g. a red-shifted absorption spectrum and a peroxidase activity towards chloride. It has been suggested that this is caused by the unusual covalent links between the heme group and the surrounding protein, but whether it is caused by the two ester links to Glu-242 and Asp-94 or the sulfonium ion linkage to

Adaptive radiations have long served as living libraries to study the build-up of species richness; however, they do not provide good models for radiations that exhibit negligible adaptive disparity. Here, we review work on damselflies to argue that nonadaptive mechanisms were predominant in the radiation of this group and have driven species divergence through sexual selection arising from male-f

MYBL2 is a transcription factor, which regulates the expression of genes involved in cancer progression. In this study, we investigated whether putative functional variants in genes regulating MYBL2 (E2F1, E2F3 and E2F4) or in genes, which are regulated by MYBL2 (BCL2, BIRC5, COL1A1, COL1A2, COL5A2, ERBB2, CLU, LIN9 and TOP2A) affect breast cancer (BC) susceptibility and clinical outcome. Twenty-e

Suppose that a circular fire spreads in the plane at unit speed. A fire fighter can build a barrier at speed v > 1. How large must v be to ensure that the fire can be contained, and how should the fire fighter proceed? We provide two results. First, we analyze the natural strategy where the fighter keeps building a barrier along the frontier of the expanding fire. We prove that this approach conta

Left ventricular function is altered during and after AMI. Regional function can be determined by cardiac magnetic resonance (CMR) wall thickening, and velocity encoded (VE) strain analysis. The aims of this study were to investigate how regional myocardial wall function, assessed by CMR VE-strain and regional wall thickening, changes after acute myocardial infarction, and to determine if we could

Objective To elucidate psychosexual problems in women referred for colposcopy after an abnormal cervical smear and a 6-month and 2-year follow up. Design Prospective study. Setting Department of Gynaecology, Malmö University Hospital, Sweden. Population One hundred consecutive women referred for colposcopy for the first time subsequent to receiving notification of an abnormal cervical smear. M

Although it has been shown that aggrecanases are involved in aggrecan degradation, the role of MMP (matrix metalloproteinase) aggrecanolysis is less well studied. To investigate MMP proteolysis of human aggrecan, in the present study we used neoepitope antibodies against MMP cleavage sites and Western blot analysis to identify MMP-generated fragments in normal and OA (osteoarthritis/osteoarthritic

Background: The diversity of the Swedish population has increased substantially over the past three decades. The aim of this study was to assess whether living in an ethnic enclave is associated with risk of diabetes mellitus (DM) among first and second-generation immigrants and native Swedes. Methods: Cumulative incidence of DM in three urban municipalities was assessed from 2006-2010 by linking

Background The prognosis in adults with congenital aortic valve disease is usually favourable; nevertheless, a number of medical and social factors might hamper long-term prognosis and quality of life. With a focus on physical exercise level, data from the Swedish National Registry on Congenital Heart Disease (SWEDCON) were analysed and variables associated with health-related quality of life in a

Patients with a clinical picture of acute ischemic stroke are a heterogeneous group. The aim of this study was to evaluate the added utility of CT perfusion (CTP) and CT angiography (CTA) in the workup of three different categories of acute ischemic stroke patients. Fifty patients (61 +/- 05 years old) were included in this retrospective analysis. Twenty-nine patients had transient ischemic attack

Several phenomena in physics and chemistry (such as phase-transitions, chemical reactions and structural changes in biomolecules) are driven on timescales in the fs range. To probe these phenomena short photon pulses of sufficiently short wavelength to directly probe the structure are necessary. The MAX IV proposal includes a short-pulse facility (SPF) which will be able to give these pulses. In t
