Growth of High Material Quality Group III-Antimonide Semiconductor Nanowires by a Naturally Cooling Process

We report on a simple but powerful approach to grow high material quality InSb and GaSb nanowires in a commonly used tube furnace setup. The approach employs a process of stable heating at a high temperature and then cooling down naturally to room temperature with the nanowire growth occurred effectively during the naturally cooling step. As-grown nanowires are analyzed using a scanning electron m

First-time parents' prenatal needs for early parenthood preparation : A systematic review and meta-synthesis of qualitative literature

Objective: contribute to the existing body of knowledge about the specific needs of first-time parents specifically for early parenthood. Method: the databases PubMed, MEDLINE, PSYCINFO, CINAHL, EMBASE, Family Studies Abstracts, and Web of Science, were searched using search terms: prenatal, antenatal, preparation, education, parents, parenthood. The meta-synthesis included 12 articles representin

4D analysis of the microstructural evolution of Si-based electrodes during lithiation : Time-lapse X-ray imaging and digital volume correlation

Silicon is a promising candidate to substitute or complement graphite as anode material in Li-ion batteries due, mainly, to its high energy density. However, the lithiation/delithiation processes of silicon particles are inherently related to drastic volume changes which, within a battery's physically constrained case, can induce significant deformation of the fundamental components of the battery

Managing Medical Emergency Calls

This dissertation is a conversation analytic examination of recurrent practices of interaction in medical emergency calls. The study expands the analytical focus in past research on emergency calls between emergency call operators and callers to pre-hospital emergency care interaction on the phone between nurses, physicians and callers. The investigation is based on ethnographic fieldwork in a Swe

Inflammatory processes are specifically enhanced in endothelial cells by placental-derived TNF-α : Implications in preeclampsia (PE)

Introduction There is a consensus that factors released by the placenta to maternal circulation, including TNF-α, play a key role in activating the maternal endothelium in pregnancies with preeclampsia (PE). Dual perfusion preserves the structural organization of the placenta to a greater degree than other in vitro systems and has been used by our group and others to examine placental pathophysiol

Fast Mitigation of Sudden Termination Changes in Wideband Wireline Systems

Vectoring enables cooperative crosstalk mitigation in wideband wireline systems. A sudden termination change within a vectored group alters the entire perceived channel matrix and thus disturbs the vectoring operation since the precoder, which is tuned to the channel before the change, is no longer up to date. We analyze the resulting residual crosstalk and its impact on performance degradation du

The Roles of the Host and the Pathogens in Urinary Tract Infections

The severity of urinary tract infections (UTIs) varies depending on the balance between the virulence of the infecting bacterial strain and the antibacterial host defense. Bacterial virulence is determined by a complex of factors in which bacterial adherence to the uroepithelium is the most important virulence factor, in addition to the production of toxins and the formation of biofilm. In immunoc

Coding variation in ANGPTL4, LPL, and SVEP1 and the risk of coronary disease

BACKGROUND: The discovery of low-frequency coding variants affecting the risk of coronary artery disease has facilitated the identification of therapeutic targets. METHODS: Through DNA genotyping, we tested 54,003 coding-sequence variants covering 13,715 human genes in up to 72,868 patients with coronary artery disease and 120,770 controls who did not have coronary artery disease. Through DNA sequ

Putting the Genome in Context : Gene-Environment Interactions in Type 2 Diabetes

The genome is often the conduit through which environmental exposures convey their effects on health and disease. Whilst not all diseases act by directly perturbing the genome, the phenotypic responses are often genetically determined. Hence, whilst diseases are often defined has having differing degrees of genetic determination, genetic and environmental factors are, with few exceptions, insepara

Incidence, clinical presentation and mortality of liver cirrhosis in Southern Sweden : A 10-year population-based study

Summary Background In Sweden, the most common causes of liver cirrhosis are alcohol overconsumption and hepatitis C. However, recent data on the clinical characteristics of Swedish patients with cirrhosis are scarce. Aims To determine the incidence, clinical presentation, aetiological spectrum and survival rates of liver cirrhosis in Southern Sweden from 2001 to 2011. Methods We used population-ba

Long-term effects of neighbourhood deprivation on diabetes risk : Quasi-experimental evidence from a refugee dispersal policy in Sweden

Background: Although studies have shown associations between neighbourhood quality and chronic disease outcomes, such associations are potentially confounded by the selection of different types of people into different neighbourhood environments. We sought to identify the causal effects of neighbourhood deprivation on type 2 diabetes risk, by comparing refugees in Sweden who were actively disperse

SAH guided spatial split partitioning for fast BVH construction

We present a new SAH guided approach to subdividing triangles as the scene is coarsely partitioned into smaller sets of spatiallycoherent triangles. Our triangle split approach is integrated into the partitioning stage of a fast BVH construction algorithm, butmay as well be used as a stand alone pre-split pass. Our algorithm significantly reduces the number of split triangles comparedto previous m

Elevated levels of iNKT cell and NK cell activation correlate with disease progression in HIV-1 and HIV-2 infections

OBJECTIVE:: In this study we aimed to investigate the frequency and activation of invariant natural killer T (iNKT) cells and natural killer (NK) cells among HIV-1, HIV-2, or dually HIV-1/HIV-2 (HIV-D)-infected individuals, in relation to markers of disease progression. DESIGN:: Whole blood samples were collected from treatment-naïve HIV-1 (n?=?23), HIV-2 (n?=?34) and HIV-D (n?=?11) infected indiv

Excess maternal transmission of variants in the THADA gene to offspring with type 2 diabetes

Aims/hypothesis: Genome-wide association studies (GWAS) have identified more than 65 genetic loci associated with risk of type 2 diabetes. However, the contribution of distorted parental transmission of alleles to risk of type 2 diabetes has been mostly unexplored. Our goal was therefore to search for parent-of-origin effects (POE) among type 2 diabetes loci in families. Methods: Families from the

Ongoing Pharmacological Management of Chronic Pain in Pregnancy

The article discusses possible effects of the use of analgesics during pregnancy. It summarizes the pertinent literature and reports some previously unpublished data from the Swedish Medical Birth Register. Most likely the use of analgesics does not cause spontaneous abortion. Only small malformation risk increases are seen after the use of opioids and perhaps non-steroid anti-inflammatory drug (N

Uncertainty in clinical practice - An interview study with Swedish GPS on patients with sore throat

Background: Uncertainty is inevitable in clinical practice in primary care and tolerance for uncertainty and concern for bad outcomes has been shown to vary between physicians. Uncertainty is a factor for inappropriate antibiotic prescribing. Evidence-based guidelines as well as near-patient tests are suggested tools to decrease uncertainty in the management of patients with respiratory tract infe
