PURPOSE: To compare progressive dynamic, relative quantitative changes in glycans associated with retinal proteins of wild type (wt) and retinal degeneration 1 (rd1) mice during neonatal development and degeneration of retinae. METHODS: Proteins extracted from retinae of postnatal day 2 (PN2), PN7, PN14 wt and rd1 mice were labeled with Cy3-fluorescent dye. Glycome of these proteins was quantified
Background: Lewy body Dementia (LBD) is a well-known neurocognitive disorder in the elderly. The hallmarks of LBD are Parkinsonism without tremor, recurrent and persistent visual hallucinations often with insight, fluctuating cognition and alertness, rapid eye movement (REM) sleep behavior disorder with vivid dreams and violent movements, but relatively preserved memory functions. Nevertheless, LB
This licentiate thesis in industrial design concerns the challenge and opportunity to meet the demographic changes and the future senior market. The aim is to explore how various user-centered design methods can be combined, modified and practiced to create conditions for the design of totally new or improved products. Design is understood as a process to develop solutions with the starting point
Industrial biotechnology has been defined as the use and application of biotechnology for the sustainable processing and production of chemicals, materials and fuels. It makes use of biocatalysts such as microbial communities, whole-cell microorganisms or purified enzymes. Although biocatalysts are considered advantageous, since they operate under mild conditions regarding temperature and pH and e
Background Bariatric metabolic surgery (Roux-en-Y gastric bypass [RYGB] and sleeve gastrectomy [SG]) effectively treats obesity and type 2 diabetes; however, weight loss varies, necessitating predictive factors. Methods We analysed 12- and 24-month weight loss data from 811 patients (RYGB or SG). Factor Analysis of Mixed Data and neural network (NN) modelling identified distinct patient phenotypes
PURPOSE: The incidence of colorectal cancer (CRC) is increasing in individuals aged < 50 years of age. This study aimed to examine whether high-frequency follow-up after CRC surgery reduces 5-year overall mortality, cancer-specific mortality and recurrence in patients with CRC aged ≤ 50 years. METHODS: The COLOFOL trial performed between 2006 and 2010 was used to analyse patients randomised to hig
Objective: Worse women's outcomes after elective standard endovascular aneurysm repair have been widely reported. Similar data have surfaced from cohorts undergoing fenestrated and branched repair; however, studies reporting from a sex perspective are rare and mostly limited to single centre designs. This study aimed to examine survival following nationwide complex endovascular repair according to
Objective: To characterize patients with protein-losing enteropathy (PLE) diagnosed before age 18 years within a nationwide Swedish Fontan cohort. Methods: Surgical records and medical charts were reviewed for all patients born after January 1, 1993, who underwent Fontan completion before January 1, 2021. Results: Among 573 reviewed patients, 28 (4.8%) developed PLE. The median time to onset of PL
BACKGROUND In patients with acute myocardial infarction (MI), therapies that could further reduce the risk of adverse cardiovascular and metabolic outcomes are needed. METHODS In this international registry-based, randomized, double-blind trial, patients without prior diabetes or chronic heart failure, presenting with acute MI and impaired left ventricular systolic function, were randomly assigned
ObjectiveTo determine whether the genetic disorder severe α1-antitrypsin deficiency, which has a known association with increased risk for development of lung and liver diseases, is also associated with increased risk for development of gastrointestinal diseases.Patients and MethodsWe conducted a national, longitudinal, registry-based study of individuals with severe α1-antitrypsin deficiency (phe
Purpose: Reduced rapid-eye movement (REM) sleep has been linked to increased mortality in the general population. We investigated whether diminished REM sleep is associated with higher mortality in adults with coronary artery disease (CAD) and obstructive sleep apnea (OSA). Methods: This secondary analysis of the RICCADSA trial included 356 revascularized CAD patients with OSA (apnea–hypopnea inde
Background: Helicobacter pylori (Hp) and its virulence factor Cytotoxin-associated gene A (CagA) have been linked to myocardial infarction (MI), but the mechanisms are unknown. This study aims to test if Hp infection and CagA are associated with pre-specified inflammatory and vascular biomarkers in patients with MI and to explore whether a broader biomarker panel can predict infection. Furthermore
Context: Glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) are cleaved by dipeptidyl peptidase-4 (DPP-4); plasma activity of DPP-4 may be increased in obesity. The impact of this increase on incretin hormone secretion and metabolism is not known. Objective: The aim of the study was to assess incretin hormone secretion and degradation in lean and obese nondiabet
Popular Abstract in Swedish Patienter med diabetes mellitus har högt blodsocker. Insulin reglerar blodsockervärdena. Redan i slutet av 1800 talet föreslogs att skulle det finnas två olika typer av diabetes, den ena beroende på bristande insulinbildning, den andra beroende på bristande insulineffekt. I början av 1900 talet utvecklades insulinframställningen. Observationer av blodsockernivåerna i blThe Diabetes Incidence Study in Sweden (DISS) registers diabetes in young adults aged 15-34 years in Sweden. This thesis aims to validate the ascertainment, methods in the classification of diabetes, and putative etiological factors such as family background, psychological stress, and BMI, that may affect the incidence of diabetes in young adults, in the DISS registry. The capture-recapture method
Popular Abstract in Swedish Denna avhandling behandlar design, tillverkning, karakterisering och optimering av elektroniska komponenter alla baserade på kvantmekanisk tunnling. Tunnling är ett rent kvantmekaniskt fenomen utan någon klassisk motsvarighet, som först blir relevant då dimensionerna krymper ner i nanometerskala (en nanometer är en miljarddel's meter). Då kan elektroner ”tunnla” igenomThis thesis concerns different kinds of tunneling based devices all showing negative differential resistance. The thesis is divided in three parts, resonant tunneling transistors, Esaki diodes and coupled zero dimensional systems. The resonant tunneling transistors are GaAs-based vertical field effects transistors, based on a combination of overgrown tungsten gates and double barrier heterostruct
OBJECTIVES: To investigate whether the interleukin-1 receptor antagonist (Il-1ra) and interleukin-1beta (Il-1beta) can be detected in human carotid artery tissue, and whether their presence is related to evidence of Chlamydia pneumoniae infection, risk factors for atherosclerosis, and clinical data. SETTING: Departments of Vascular Diseases and Surgical Pathophysiology, University Hospital, Malmö,
BACKGROUND AND PURPOSE: To assess the prevalence of asymptomatic abnormalities on magnetic resonance imaging of the brain and their possible relation to hypertension, heart disease, and carotid artery disease, we studied 77 randomly selected subjects (mean age, 65.1 years; range, 36 to 95 years) with no history of focal brain lesions. METHODS: The study protocol included magnetic resonance imaging
Background— Carotid intima-media thickness (IMT) is increasingly used as a surrogate marker for atherosclerosis. Its use relies on its ability to predict future clinical cardiovascular end points. We performed a systematic review and meta-analysis of data to examine this association. Methods and Results— Using a prespecified search strategy, we identified 8 relevant studies and compared study des
Purpose: To assess and correlate the levels of inflammatory mediators in the eyes from non-diabetic and diabetic subjects without retinopathy (NDR), with non-proliferative diabetic retinopathy (NPDR) or with proliferative diabetic retinopathy (PDR) to corresponding erum levels. Methods: The levels of interleukin 1β, interleukin-6 (IL-6) and tumour necrosis factor-α (TNF-α) were analysed by an EL
Background: The effects on left and right ventricular (LV, RV) volumes during physical exercise remains controversial. Furthermore, no previous study has investigated the effects of exercise on longitudinal contribution to stroke volume (SV) and the outer volume variation of the heart. The aim of this study was to determine if LV, RV and total heart volumes (THV) as well as cardiac pumping mechani
