Popular Abstract in Swedish Mellanörats funktion är att överföra och förstärka ljudvågor från luften i hörselgången till innerörats vätska. Denna överföring är optimal när trumhinnan är i neutral position, dvs när trycket i mellanörat och omgivningen är lika. Avvikelser i mellanörats tryck ses vid kroniska mellanöresjukdomar, fr a är det visat ett samband mellan negativt tryck och sjukdomstillstånThe middle ear (ME) pressure is regulated by gas diffusion over the ME mucosa and pressure equalizations via the Eustachian tube (ET). Disturbance in the regulation of ME pressure is believed to contribute to the development of chronic ear diseases. In this work subjects with chronic central perforation (CCP), healthy ears with ventilation tubes (VTs), attic cholesteatoma (AC) and Meniere’s diseas

We sought to propose and test the validity of a comprehensive prognostic model in middle cerebral artery-stroke treated with Intravenous thrombolysis. A total of 127 consecutive patients (aged 70 +/- 12 years; 54% males) were included in this retrospective study. Variables included in our prognostic model were: NIHSS on admission (1-3 points), occurrence of hyperdense middle cerebral artery sign a

Background: Pancreatic cancer and other pancreaticobiliary type periampullary adenocarcinomas have a dismal prognosis even after resection and neoadjuvant chemotherapy. Intestinal type periampullary adenocarcinomas generally have a better prognosis, but little is known on optimal neoadjuvant and adjuvant treatment. New prognostic and treatment predictive biomarkers are needed for improved treatmen

Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING PÅ SVENSKA Graviditetsdiabetes (GDM) definieras som ett diabetestillstånd som upptäcks under graviditet. Ofta orsakas detta tillstånd av de hormonförändringar som uppträder under graviditet vilka medför en ökad insulinresistens, dvs. ett ökat motstånd mot insulinets effekter. Diagnosen GDM utesluter dock inte diabetes av annan orsak soThe aims of this work were to determine the prevalence of postpartum diabetes among women with gestational diabetes mellitus (GDM) in a prospective study 5 years postpartum; to characterize these women according to insulin secretion, insulin sensitivity, autoimmunity and genetics; and to identify possible markers and predictors for the development of manifest diabetes. The subjects were recruited

Bo Rothsteins genomgång av svensk välfärdsforskning innehåller några orättvisa betraktelser som inte bör stå oemotsagda. Kommentaren fokuserar på felaktigheter vad gäller asymmestrisk information och tveksamheter vad gäller den svenska pensionsreformen

BACKGROUND: Cluster headache is a primary headache by definition not caused by any known underlying structural pathology. However, symptomatic cases have been described, e.g. tumours, particularly pituitary adenomas, malformations, and infections/inflammations. The evaluation of cluster headache is an issue unresolved. CASE DESCRIPTION: We present a case of a 43-year-old patient who presented with

This paper is devoted to the continuation of solutions to the Camassa-Holm equation after wave breaking. By introducing a new set of independent and dependent variables, the evolution problem is rewritten as a semilinear hyperbolic system in an L-infinity space, containing a non-local source term which is discontinuous but has bounded directional variation. For a given initial condition, the Cauch

The genus Pseudexechia Tuomikoski is re-characterized and described, including a thorough morphological study of the male and female terminalia, providing homology assessment of the various parts and substructures. The 25 currently known species of Pseudexechia are tentatively grouped into four species groups that are characterized mainly by structures of the male terminalia: the canalicula group

Electrochemical methods employing the hanging mercury drop electrode were used to study the interaction between variants of the complement-derived antimicrobial peptide CNY21 (CNYITELRRQH ARASHLGLAR) and dioleoyl phosphatidylcholine (DOPC) monolayers. Capacitance potential and impedance measurements showed that the CNY21 analogues investigated interact with DOPC monolayers coating the mercury drop

This paper describes an explorative user study of how two different user groups experience current, as well as envisioned new mobile navigation systems. Two groups have been the primary target in this study; a group of elderly people and a group of relatively young university students that were visually impaired. The study consisted of three parts: a focus group/test, a diary study and a design wo

The aim of this study was to examine the effect of total parenteral nutrition (TPN) on the endocrine and exocine function of the pancreas. Endocrine function was investigated using an intravenous glucose tolerance test (IGTT) in rats with TPN for 7 or 14 days. Exocrine function was evaluated by measuring amylase secretion from isolated acini as well as pancreatic weight, water content, protein, an

The design and layout of a two stage SiGe E-band power amplifier using a stacked transformer for output power combination is presented. In EM-simulations with ADS Momentum, at E-band frequencies, the power combiner consisting of two individual single turn transformers performs significantly better than a single 2:1 transformer with two turns on the secondary side. Imbalances in the stacked transfo

Context: The diagnosis of and reporting parameters for prostate cancer (PCa) have evolved over time, yet they remain key components in predicting clinical outcomes. Objective: Update pathology reporting standards for PCa. Evidence acquisition: A thorough literature review was performed for articles discussing PCa handling, grading, staging, and reporting published as of September 15, 2011. Electro

Are voiceless approximants categorically distinct from voiceless fricatives? We address this question by means of acoustic analysis of voiceless laterals in Icelandic, Welsh, and the endangered variety Estonian Swedish. All three have a voiceless lateral functioning in contrast to a voiced lateral approximant. The analysis focused on duration – including any period of voicing (‘pre-voicing’) just
