Background Improving knowledge of obstetric danger signs and promoting birth preparedness practices are strategies aimed at enhancing utilization of skilled care in low-income countries. The aim was to explore the association between knowledge of obstetric danger signs and birth preparedness among recently delivered women in south-western Uganda. Methods The study included 764 recently delivered

In this thesis we present friction studies on InAs nanowires pushed laterally across surfaces by an AFM tip. The contact length in the direction of movement is of the order of a few tens of nanometers, and is thus comparable to that found in existing point-contact studies, but perpendicular to the motion the wire can be several microns in length. We are therefore able to investigate friction in th

In this presentation will be given an up-date of the status of epitaxially grown III-V nanowires, from the perspective of growth, processing, physics and applications in the areas of nanoelectronics and nanophotonics

This book uses the case of the Artists' House, a cultural center in Tehran, to place the socio-political implications of Iran's social and cultural transformation in a local-global context. The author examines the bipolar dimension of openness to change versus conservation and the role of these values in Iranian society generally as well as in the context of everyday life in Tehran. The text addre

The incidence of Hodgkin lymphoma has increased among adolescents and young adults in recent decades, but the relevant risk factors in early life are still unknown. A national cohort study was conducted of 3,571,574 individuals born in Sweden in 19732008 and followed up for Hodgkin lymphoma incidence through 2009, to examine perinatal and family risk factors for Hodgkin lymphoma in childhood throu

Recently, molecular motor gliding assays with actin and myosin from muscle have been realized on semiconductor nanowires coated with Al2O3. This opens for unique nanotechnological applications and novel fundamental studies of actomyosin motor function. Here, we provide a comparison of myosin-driven actin filament motility on Al2O3 to both nitrocellulose and trimethylchlorosilane derivatized surfac

Objectives: The objective of this study was to define metabolic normality and to investigate the cardiometabolic profile of metabolically normal obese. Design: Cross-sectional study conducted at 21 research centers in Europe. Subjects: Normal body weight (nbw, n = 382) and overweight or obese (ow/ob, n = 185) subjects free from metabolic syndrome and with normal glucose tolerance, were selected am

We report on the discovery of a generic piezoelectric field in strained core-shell compound semiconductor nanowires. We present the lattice-mismatch induced strain in epitaxial core-shell nanowires and show that it gives, very generally, rise to an internal piezoelectric field along the axis of the nanowire. This field results predominantly from atomic displacements in polar bonds and microscopic

Background: Age at first and last birth and the number of children are known to influence the risk of endometrial and ovarian cancers. However, it remains unknown whether the difference in years between first and last childbirth plays a role. The Swedish Family-Cancer Database allowed us to carry out the largest study ever on reproductive factors in these cancers. Material and methods: We selected

In this work, we report a method that allows the deterministic, photo-controlled covalent assembly of nanoparticles directly on surface. As a model system, we study the conjugation of molecularly imprinted polymer (MIP) nanoparticles on a glass surface and confirm that the immobilized nanoparticles maintain their molecular recognition functionality. The glass slide was first modified with perfluor

A new extracellular flavin adenine dinucleotide (FAD)-dependent glucose dehydrogenase from Glomerella cingulata (GcGDH) was electrochemically studied as a recognition element in glucose biosensors. The redox enzyme was recombinantly produced in Pichia pastoris and homogeneously purified, and its glucose-oxidizing properties on spectrographic graphite electrodes were investigated. Six different Os

Fabrication and application of a non-fluorescent and UV-transparent microfluidic biochip in fused silica that allows sensitive autofluorescence detection are described. The biochip is particularly useful in cell-based assays where the most informative autofluorescence signals from the cells reside in the ultraviolet spectral range and where plastic labware materials commonly used in cell culture w

One-dimensional superconducting transistors have been fabricated with individual InAs nanowires (NWs) using radio-frequency sputter cleaning followed by in situ metal deposition. Because of the highly transparent contacts formed in between the InAs NWs and the metals, supercurrent, multiple Andreev reflections and Shapiro steps under microwave radiation have been observed. Near pinch-off gate regi

Low throughput is an inherent problem associated with most single-molecule biophysical techniques. We have developed a versatile tool for high-throughput analysis of DNA and DNA-binding molecules by combining microfluidic and dense DNA arrays. We use an easy-to-process microfluidic flow channel system in which dense DNA arrays are prepared for simultaneous imaging of large amounts of DNA molecules

Context:Genome-wide association studies (GWASs) of differentiated thyroid cancer (DTC) have identified associations with polymorphisms at 2q35 (DIRC3), 8p12 (NRG1), 9q22.33 (FOXE1) and 14q13.2 (NKX2-1). However, most of the inherited genetic risk factors of DTC remain to be discovered.Objective:Our objective was to identify additional common DTC susceptibility loci.Design:We conducted a GWAS in a

Background Prostate cancer is one of the leading causes of death from malignant disease among men in the developed world. One strategy to decrease the risk of death from this disease is screening with prostate-specific antigen (PSA); however, the extent of benefit and harm with such screening is under continuous debate. Methods In December, 1994, 20 000 men born between 1930 and 1944, randomly sam
