Simultaneous laser-induced fluorescence (LIF) imaging of formaldehyde and a fuel-tracer have been performed in a direct-injection HCCI engine. A mix of N-heptane and iso-octane was used as fuel and Toluene as fluorescent tracer. The experimental setup involves two pulsed Nd:YAG lasers and two ICCD cameras. Frequency-quadrupled laser radiation at 266 nm from one of the Nd:YAG lasers was used for ex
The Second String Quartet by Arnold Schoenberg, written in 1907 and 1908, is breaking musical traditions at least twice – (1) by leaving tonality, (2) by breaking the genre of string quartet, adding a voice who is interpreting two poems by the German symbolist Stefan George in its third and forth movements. In this paper, I want to raise the question about the reasons why Schoenberg might have add
Popular Abstract in Swedish Avfall har alltid uppkommit i alla samhällen i alla tider. Det vanligaste sättet att hand om det har varit att samla avfallet i soptippar (deponier) på mark som ansetts obrukbar, t.ex. i sankmarker utanför bebyggelsen. I takt med ökad konsumtion och produktion har också mängderna avfall ökat. Anledningen till att avfall och avfallshantering kommit alltmer i fokus i miljA methodology based on an analytical protocol for evaluation of hazards from landfill leachate and solid waste is described. A dynamic analytical protocol, the LAQUA protocol, including measurements of inorganic and water-quality parameters, polar and non-polar organic marker compounds, and toxicity, was constructed. An acute toxicity test, using the brackish water crustacean Artemia salina as tes
Intestinal alkaline sphingomyelinase (alk-SMase) generates ceramide and inactivates platelet-activating factor (PAF) and is previously suggested to have anticancer properties. The direct evidence is still lacking. We studied colonic tumorigenesis in alk-SMase knockout (KO) mice. Formation of aberrant crypt foci (ACF) was examined after azoxymethane (AOM) injection. Tumor was induced by AOM alone,
The aim of this study was to assess the clinical value of preoperative blood levels of HE4 as a predictor of overall survival in patients with ovarian cancer and to validate previous data of HE4 and the ROMA algorithm including HE4 and CA125 in discriminating benign and malignant ovarian tumors. Experimental design: The preoperative plasma levels of HE4 and CA125 were analyzed with ELISA in 312 pa
Popular Abstract in Swedish Delarbetena i denna avhandling, som baseras på en befolkningsstudie från Malmö, studerar sjuklighet och dödlighet associerad till rökning och kroniska luftrörssjukdomar med hänsyn till köns och socioekonomiska aspekter. Studier av män har övertygande visat en ökad mortalitetsrisk associerat med tobaksrökning. Emellertid har endast ett fåtal studier undersökt långtidsefThe Malmö Preventive Project, a preventive, case-finding programme for cardiovascular risk factors and alcohol abuse was created in 1974 at the Department of Preventive Medicine of Malmö University Hospital. Between 1974-1992, a total of 22 444 men (mean age 44 years range 27 - 61) and 10 902 women (mean age 50 years, range 28 - 58) attended the programme, with an overall attendance rate of 70% (r
Background. It is well known that portacaval shunting ultimately leads to a decrease in liver volume and hepatic function, but the mechanism is uncertain. The aim of the present study was to evaluate the effect of portacaval shunting (PCS) upon the morphological changes that occur in the liver in rats after port caval. anastomosis. Materials and methods. Sixty-six male rats underwent either PCS (n
Background: Serum protein profiles have been investigated frequently to discover early biomarkers for breast cancer. So far, these studies used biological samples collected at or after diagnosis. This may limit these studies' value in the search for cancer biomarkers because of the often advanced tumor stage, and consequently risk of reverse causality. We present for the first time pre-diagnostic
The reactions of [Fe2(CO)6(μ-sdt)] (1) (sdt = SCH2SCH2S) with phosphine ligands have been investigated. Treatment of 1 with dppm (bis(diphenylphosphino)methane) or dcpm (bis(dicyclohexylphosphino)methane) affords the diphosphine-bridged products [Fe2(CO)4(μ-sdt)(μ-dppm)] (2) and [Fe2(CO)4(μ-sdt)(μ-dcpm)] (3), respectively. The complex [Fe2(CO)4(μ-sdt)(κ2-dppv)] (4) with a chelating diphosphine was
This article investigates the creation and circulation of class knowledge among Sweden's political parties as Swedish representative democracy took shape, 1911-1940. When the expanded franchise for men was introduced in the general election of 1911, the National Statistics Bureau (SCB) was tasked with categorising voters to measure the effects of the reform. They created a taxonomy made up of thre
Tactile feedback plays a vital role in inducing ownership and improving motor control of prosthetic hands. However, commercially available prosthetic hands typically do not provide tactile feedback and because of that the prosthetic user must rely on visual input to adjust the grip. The classical rubber hand illusion (RHI) where a brush is stroking the rubber hand, and the user's hidden hand synch
INTRODUCTION: Rapid response teams (RRTs) are designed to improve the "chain of prevention" of in-hospital cardiac arrest (IHCA). We studied the 30-day survival of patients reviewed by RRTs within 24 hours prior to IHCA, as compared to patients not reviewed by RRTs.METHODS: A nationwide cohort study based on the Swedish Registry of Cardiopulmonary Resuscitation, between January 1st, 2014, and Dece
Background: Healing failure after rotator cuff repair is a challenging problem. Acute, trauma-related tears are considered a separate entity and are often treated surgically. The aim of this study was to identify factors associated with healing failure in previously asymptomatic patients with trauma-related rotator cuff tears treated with early arthroscopic repair. Methods: This study included 62
Background: Traumatic brain injury causes morbidity, mortality, and at least 2,500,000 yearly emergency department visits in the USA. Computerized tomography of the head is the gold standard to detect traumatic intracranial hemorrhage. Some are not diagnosed at the first scan, and they are denoted “delayed intracranial hemorrhages. ” To detect these delayed hemorrhages, current guidelines for head
Objectives: To study the risk of osteoporosis-related fractures in a community-based sample of men and women with rheumatoid arthritis (RA) overall, as well as early (< 1 year of disease duration, follow-up time maximum 10 years) and established (RA diagnosis since ≥ 5 years on July 1, 1997) RA, compared with the general population. To study potential risk factors for fractures in patients with RA
Aims: The association between cancer and survival after out-of-hospital cardiac arrest (OHCA) has not been thoroughly investigated. We aimed to address this knowledge gap using national, population-based registries. Methods and results: For this study, 30 163 patients with OHCA (≥18 years) were included from the Swedish Register of Cardiopulmonary Resuscitation. Through linkage to the National Pat
Importance: Despite the large health burden, reliable data on sepsis epidemiology are lacking; studies using International Statistical Classification of Diseases and Related Health Problems (ICD)-coded hospital discharge diagnosis for sepsis identification suffer from limited sensitivity. Also, ICD data do not allow investigation of underlying pathogens and antimicrobial resistance. Objectives: To
Purpose: Bone marrow is the primary site of skeletal metastases in prostate cancer. 18F-sodium fluoride (NaF) can be used to detect malignant activity, but also identifies irrelevant degenerative cortical uptake. Normal radiotracer activity in solely the marrow has yet to be described and could be a first step towards automated tumor burden calculation as SUV thresholds. We aimed to investigate no
Background The incidence of people diagnosed with cancer is increasing worldwide, in Sweden with approximately 65 000 new cases yearly. To enhance conditions for a continued good life, high-quality, accessible and equal cancer rehabilitation is required. In 2020 the National Board of Health and Welfare (NBHW) received a government assignment to investigate the conditions for the offer of cancer re
Objective: Survivors of childhood, adolescent, and young adult (CAYA) cancer have an increased risk of metabolic syndrome (MetS). MetS describes the clustering of cardiovascular risk factors including overweight or obesity, hypertension, (pre)diabetes, and dyslipidaemia. While associated cardiovascular sequelae can be serious, MetS is preventable, manageable, and potentially reversible with the ap
