This paper gives a brief summary of computational methods in heat transfer equipment, i.e., CFD (computational fluid dynamics) methods for thermal problems, and turbulence modeling for single phase applications in the design, research and development of heat exchangers. Some examples for real heat exchangers are shown to demonstrate how CFD methods can be used as R & D tools. Nevertheless, lim

OBJECTIVE: High concentrations of leukocytes in blood have been associated with diabetes mellitus. This prospective study aimed to explore whether total and differential leukocyte counts are associated with incidence of diabetes. A missense variant R262W in the SH2B3 (SH2B adaptor protein 3) gene, coding for a protein that negatively regulates hematopoietic cell proliferation, was also studied in

The aim of this project is to explore and understand the combustion phenomenon in engines operating on gaseous fuels, and develop technologies as an alternative to the present diesel engine technologies for heavy duty applications; which are facing severe challenges like stringent emissions norms, high technology costs and unsustainable fuel supply. The studies presented in this thesis focus on th

Background: Ingestion of a meal increases the blood flow to the gastrointestinal organs and affects the heart rate (HR), blood pressure and cardiac output (CO), although the mechanisms are not known. The aim of this study was to evaluate the effect of endogenously released glucose, insulin, glucagon-like peptide 1 (GLP-1), ghrelin on CO, HR, stroke volume (SV), and blood pressure. Methods: Eleven

OBJECTIVE: This study assessed prognostic factors regarding long-term outcome for amputation and death among patients who underwent intra-arterial thrombolysis due to lower limb ischemia. METHODS: Consecutive patients with intra-arterial thrombolysis due to lower limb ischemia treated at the Department of Vascular Diseases, University Hospital of Malmö, between January 1, 2001, and December 31, 20

In experimentally induced myocardial ischemia, mild hypothermia (33-35 degrees C) has a robust cardioprotective effect. Tissue plasminogen activator (t-PA) is a profibrinolytic enzyme that is released from the vascular endothelial cells in response to ischemia and other injurious stimuli. t-PA has also been found to have proinflammatory properties that could contribute to reperfusion injury. We po

Background: While simultaneous saccharification and co-fermentation (SSCF) is considered to be a promising process for bioconversion of lignocellulosic materials to ethanol, there are still relatively little demo-plant data and operating experiences reported in the literature. In the current work, we designed a SSCF process and scaled up from lab to demo scale reaching 4% (w/v) ethanol using xylos

OBJECTIVE: To investigate effects of lipid lowering drug, simvastatin, on apolipoprotein M expression in the hyperlipidemic mice and in hepatic cell line, HepG2 cells. METHODS: Swiss male mice were randomly divided into the high fat group and control group, and were intragastrically fed with 0.9% saline (control group) or lipid emulsion (high fat group) at the daily dosage of 15 ml/kg body weight

Orthostatic hypotension and long-term incidence of atrial fibrillation: the Malmo Preventive Project. J Intern Med 2010; 268: 383-389. Objectives. Orthostatic hypotension (OH), a common manifestation of autonomic dysfunction, has b

The 20q13 region is frequently amplified/overexpressed in breast tumours. However, the nature of this amplification/overexpression is unknown. Here, we investigated genetic variation in five 20q13 amplicon genes (MYBL2, AURKA, ZNF217, STK4 and PTPN1) and its impact on breast cancer (BC) susceptibility and clinical outcome. As a novel finding, four polymorphisms in STK4 (rs6017452, rs7271519) and A

Objective . Low density lipoprotein cholesterol (LDL-C) is an independent and modifiable risk factor for development of cardiovascular disease (CVD). Postprandial lipid metabolism has been linked to CVD, but little is known about the postprandial LDL-C profile in patients with type-2 diabetes (T2DM). We aimed to study the postprandial levels of LDL-C in T2DM patients. Material and methods . After

Neoliberalism, as a loosely defined set of political beliefs, calls for more individual freedom and autonomy, resulting in increased responsibility for each person to address major societal issues. ‘Individualization’ is the process by which responsibility for addressing major environmental issues such as climate change is placed on individuals. In this thesis I investigate whether individualizati

Background The perception of surgery as expensive and complex might be a barrier to its widespread acceptance in global health efforts. We did a systematic review and analysis of cost-effectiveness studies that assess surgical interventions in low-income and middle-income countries to help quantify the potential value of surgery. Methods We searched Medline for all relevant articles published betw

Background: The aim in the thesis is to study diagnostic issues, clinical features, therapy, and prognosis in selected demyelinative disorders of the nervous system: optic neuritis (ON), primary progressive MS (PPMS), and tumefactive MS (a very rare acute demyelinating disorder). Methods: From an initial cohort of 110 patients with ON collected 19 to 31 years ago, a new follow-up survey was con

BACKGROUND: Primary cervical screening with both human papillomavirus (HPV) DNA testing and cytological examination of cervical cells with a Pap test (cytology) has been evaluated in randomized clinical trials. Because the vast majority of women with positive cytology are also HPV DNA positive, screening strategies that use HPV DNA testing as the primary screening test may be more effective. METHO
