Previously, time/temperature treatments of starch have been performed mainly on starch/water systems. In this study the same time/temperature treatments were applied to starch/water systems and to potato starch in situ. Two potato varieties (Solanum tuberosum cultivars Asterix and Bintje) were used. The effect of time/temperature treatments on gelatinisation behaviour was evaluated using different
The four largest Swedish lakes, Vanern, Vattern, Malaren, Hjalmaren, host important commercial fisheries for char, salmon, trout, whitefish, vendace (cisco), perch, pike-perch, pike and eel, i.e. highly diverse biological resources. Case studies illustrate physical, chemical and biological impacts on some of these commercial species caused by constructions of dams and ship canals, eutrophication,
Popular Abstract in Swedish Idag finns det flera studier där livstillfredsställelse bland äldre har undersökts. Studierna är dels genomförda i varierande kontext och dels innehåller de varierande faktorer som hälsa, funktionell förmåga, självkänsla, sociala kontakter och finansiell situation. Därmed är det inte självklart att det finns gemensamma eller specifika faktorer, vilka är förknippade med The aim of this thesis was to investigate how older people's capacity to perform activities of daily living (ADL), health, social and financial resources, and self-esteem can be related to their life satisfaction. The aim was also to investigate how people feel hindered by health problems in relation to their ADL capacity, health problems, social and financial resources, self-esteem, sense of cohe
Batch processes are becoming more and more important in the chemical process industry, where they are used in the manufacture of specialty materials, which often are highly profitable. Some examples where batch processes are important are the manufacturing of pharmaceuticals, polymers, and semiconductors. The focus of this thesis is exception handling and fault detection in batch control. In the
Gram-negative bacteria have the ability to produce outer membrane-derived vesicles (OMVs) that are released into the extracellular milieu. Even though this intriguing phenomenon is well-known since many years, various aspects of bacterial OMVs are not fully described and are still in the process of being characterized in detail. One major reason for this is that depending on the bacterial species
Abstract The purpose of this study was to explore how persons with severe mental illness (SMI) experience oral health problems (especially dry mouth), and weigh the support they received in this regard from professionals and staff at community-based congregate housing through a controlled intervention programme. Oral health problems and dry mouth are found in association with apathy and indifferen
Increased understanding of the molecular processes associated with the dysplasia-adenocarcinoma sequence linked to Barrett's esophagus may be beneficial for early tumor detection and refined diagnosis as well as for improved prognostication. We applied immunohistochemical staining for the markers Ki-67, p53, beta-catenin and E-cadherin in order to evaluate their prognostic importance in 59 Barrett
Hepatitis B virus (HBV) infection is one of most common viral infections worldwide. While chronic HBV infection has been shown consistently to be associated with hepatocellular carcinoma, data on associations with cancers at other sites are limited. In this study a total of 10,197 patients were diagnosed with chronic HBV infection in Sweden, and they were retrieved from the nationwide Swedish Hosp
Accelerated cell aging, indexed in peripheral leukocytes by telomere shortness and in peripheral blood mononuclear cells (PBMCs) by telomerase activity, has been reported in several studies of major depressive disorder (MDD). However, the relevance of these peripheral measures for brain indices that are presumably more directly related to MDD pathophysiology is unknown. In this study, we explored
Diabetes is a much more heterogeneous disease than the present subdivision into types 1 and 2 assumes; type 1 and type 2 diabetes probably represent extremes on a range of diabetic disorders. Both type 1 and type 2 diabetes seem to result from a collision between genes and environment. Although genetic predisposition establishes susceptibility, rapid changes in the environment (ie, lifestyle facto
Popular Abstract in Swedish Vi är under ständig attack från mikroorganismer som vill leva på oss och i oss. Vissa av dessa är vanligtvis nyttiga medan andra är sjukdomsframkallande. Kroppens försvar mot invaderande organismer består av många delar. Ytterst sitter huden som en mekanisk barriär, vi har slem och epitelceller i luftvägar och magtarmkanal samt skyddande ämnen i exempelvis tårvätska. I Transplantation antigens encoded in the major histocompatibility complex (MHC) bind peptides and present them to T cells. We showed that mouse T cells expressing transgenic human CD8 can recognise human MHC class I. Expression on mature T cells is sufficient for activation in a mixed lymphocyte culture but expression both on thymocytes and mature T cells is necessary for peptide specific MHC restr
The purpose was to study age related changes in circulatory system via Ballistocardiography (BCG) by utilizing Electromechanical Film (EMFi) sensors by gradually changing the ambient temperature from a thermoneutral area to cold direction. ECG and BCG were recorded from a young person (23 years) and from an older person (78 years), both males. During the tests, brachium blood pressure (BP) and pul
Lipid bilayers containing 5% nitrilotriacetic acid (NTA) lipids supported on SiO2 have been used as a template for immobilization of oligohistidine-tagged single-chained antibody fragments (scFvs) directed against cholera toxin. It was demonstrated that histidine-tagged scFvs could be equally efficiently coupled to an NTA-Ni2+-containing lipid bilayer from a purified sample as from an expression s
BACKGROUND: The influence of tobacco smoke has been investigated on the growth rate and histology of prostate cancer, both in untreated tumors and in those subjected to fractionated irradiation. METHODS: Twenty-five rats were implanted bilaterally with Dunning R3327 tumor fragments at 10 weeks of age. Approximately 3 months later, they were randomly allocated to two groups, one of which was expose
Background There has been much debate about the value of screening mammography. Here we update the overview of the Swedish randomised controlled trials on mammography screening up to and including 1996. The Kopparberg part of the Two-County trial was not available for the overview, but the continuation of the Malmo trial (MMST II) has been added. The article also contains basic data from the trial
