Popular Abstract in Swedish De flesta människor bibehåller en relativt konstant kroppsvikt genom livet trots att mängden mat och motion varierar från dag till dag. En konstant kroppsvikt betyder att energiintag (mat och dryck) och energiutgifter (värme och rörelse) i genomsnitt är lika stora, d.v.s. kroppens energibalans är i jämvikt. Övervikt är ett resultat av positiv energibalans, vilket innebä
Popular Abstract in Swedish I det moderna samhället är vi helt beroende av polymera material, från barndomen med blöjor och nappflaskor till ålderdomen med artificiella ögonlinser och höftleder. Dagens sjukvård skulle inte klara de höga hygieniska kraven om inte engångsartiklar såsom gummihandskar, påsar för blodtransfusion och katetrar fanns. I många applikationer är polymerernas ytegenskaperna m
Abstract in UndeterminedBackground The role of allergy in the aetiopathogenesis of chronic rhinosinusitis (CRS) remains controversial. For example, in some cases with sinus fungal infections allergy can be demonstrated by standard tests. In other cases, such signs can be absent despite elevated levels of IgE-positive cells in sinus tissue and the presence of IgE and eosinophils in the sinus mucous
Abstract in UndeterminedStrategic recollection refers to control processes that allow the retrieval of information that is relevant for a specific situation. These processes can be studied in memory exclusion tasks, which require the retrieval of particular kinds of episodic information. In the current study, we investigated strategic recollection in reality monitoring by event-related potentials
Hemophilia patients with inhibitors against FVIII/FIX present with a major challenge in the clinical practice. In the 1970s such patients were treated in association with emergency situations and essential surgery using huge amounts of FVIII/FIX concentrates often preceded by extracorporal adsorption of antibodies against FVIII/FIX. However, moderate to mild bleedings were not effectively treated.
International guidelines recommend PET-CT should replace CT in Hodgkin Lymphoma (HL). The aims of this study were to i) compare PET-CT with CT for staging and ii) measure agreement between expert and local readers, using a five-point scale (Deauville criteria), to adapt treatment in a clinical trial 'Response Adapted Therapy in Advanced Hodgkin Lymphoma' (RATHL) www.cancer.gov/clinicaltrials, refe
OBJECTIVES: Expression of uPA mRNA is massively up-regulated in the stroma of poorly differentiated ovarian tumors. We hypothesized that this expression was induced by paracrine signals from the epithelial tumor cells, and established an in vitro model of ovarian cancer microenvironment to study intercellular cross-talk. METHODS: ES-2 clear cell carcinoma cells were grown in tissue culture inserts
PURPOSEHuman papillomavirus type 16 (HPV16) infection is causing an increasing number of oropharyngeal cancers in the United States and Europe. The aim of our study was to investigate whether HPV antibodies are associated with head and neck cancer risk when measured in prediagnostic sera. METHODSWe identified 638 participants with incident head and neck cancers (patients; 180 oral cancers, 135 oro
Popular Abstract in Swedish Idag kan vi mäta mycket låga halter av gifter i t. ex. dricksvatten och livsmedel, bland annat genom utvecklingen av nanosensorer. Sensorerna kan också använda's medicinskt, t. ex för att väsentligt underlätta livet för diabetiker. Idag drabba's diabetespatienter ofta av nedsatt känsel i fingrarna på grund av dagliga nålstick. Med hjälp av de nya sensorerna kan vi nu mäA new type of Bioelectronic Nanosensor Device with potential applications in medicine,biotechnology and environmental analysis was designed. The nanosensor is based on RISFET (Regional Ion Sensitive Field Effect Transistor) technology. The design of the nanosensor involves use of a set of nano-sized electrodes on the surface of a silicon chip, giving the chip the ability to sense extremely low con
Popular Abstract in Swedish Biotisk och abiotisk stress hos mikroorganismer och växter.Various forms of stress, such as biotic and abiotic stress, were studied in microorganisms and plants to learn more about the underlying mechanisms of such stress and potential genetic engineering strategies towards stress tolerance. An antifreeze protein from winter flounder, expressed in E. coli, was subjected to directed evolution with NaCl as selective pressure. The resulting clones were teste
Popular Abstract in Swedish När en organism utsätts för stress, t. ex. vid hög temperatur, starkt solljus, torka eller köld, produceras särskilda hjälpar-proteiner, s. k. ¨stress-proteiner¨. Syntesen av cellens normala proteiner stängs av och istället produceras bara stress-proteiner. Dessa stress-proteiner är till för att skydda andra protein som skadas under stress. De s. k. ¨värme-stress¨ proteA specific group of heat shock proteins, the so called small heat shock proteins (sHsps), exists in all organisms but are especially abundant in plants. The sHsps prevent aggregation of other proteins (substrate proteins) during transient heat and oxidative stress. Molten globule forms of the substrate proteins are kept in a re-folding competent state by binding onto the outer surface of the sHsp.
Exaggerated acidosis due to preischemic hyperglycemia shortens the maturation time for cell death and turns selective neuronal damage into pannecrosis. Some issues concerning the mechanisms are yet to be clarified. The present study was designed to define critical thresholds of plasma glucose, to investigate the influence of preischemic hyperglycemia on ion transients, to evaluate the role of calc
BACKGROUND: According to the World Health Organization (WHO) the cost of adverse drug reactions (ADRs) in the general population is high and under-reporting by health professionals is a well-recognized problem. Another way to increase ADR reporting is to let the consumers themselves report directly to the authorities. In Sweden it is mandatory for prescribers to report serious ADRs to the Medical
ERP systems became popular with large organizations in the 1990s. In the 21st Century, these products were expanded by addition of supply chain management (SCM) and customer relationship management (CRM), as well as access through the Web, creating the ERP II concept. Efforts to increase the market led vendors to serve not only large organizations, but also focus more on small-to-medium sized ente
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
Cancer is one of the leading causes of death worldwide, but reliable diagnosis and staging can contribute to optimal treatment planning, and is a crucial factor in reducing mortality and maintaining quality of life. Soft tissue mechanical properties are promising indicators of cancer that can be assessed non-invasively using functional imaging. Additionally, lymphatic involvement is considered a k
Telomeres are protective cap structures at the ends of the linear eukaryotic chromosomes, which provide stability to the genome by shielding from degradation and chromosome fusions. The cap consists of telomere-specific proteins binding to the respective single- and double-stranded parts of the telomeric sequence. In addition to the nucleation of the chromatin structure the telomere-binding protei
