Melanoma of the skin is the sixth most common type of cancer in Europe and accounts for 3.4% of all diagnosed cancers. More alarming is the degree of recurrence that occurs with approximately 20% of patients lethally relapsing following treatment. Malignant melanoma is a highly aggressive skin cancer and metastases rapidly extend to the regional lymph nodes (stage 3) and to distal organs (stage 4)
This thesis is a phenomenological investigation into the differences and similarities between language as speech and language as a technique. Speech is the practice of producing and understanding utterances. A technique is the organizing mechanism of speech, the structure that gives it a regular form. While speech is heavily dependent on context and interpretation, a technique is unaffected by theThis thesis is a phenomenological investigation into the differences and similarities between language as speech and language as a technique.

OBJECTIVE: To investigate the relationship between 3 markers of apoptosis, that is, FADD (Fas-associated death domain-containing protein), caspase-3, and caspase-8, and incidence of coronary events (CEs) in a population-based cohort study.APPROACH AND RESULTS: In vitro experiments were performed to assess the response of the apoptotic biomarkers after Fas stimulation of peripheral blood mononuclea
Whereas the characterization of B lymphoid progenitors has been facilitated by the identification of lineage-and stage-specific surface markers, the continued identification of differentially expressed proteins increases our capacity to explore normal and malignant B cell development. To identify novel surface markers with stage-specific expression patterns, we explored the reactivity of CD19+ B c
Background and purpose - Little is know about patterns of sick leave in connection with total hip and knee joint replacement (THR and TKR) in patients with osteoarthritis (OA). Patients and methods - Using registers from southern Sweden, we identified hip and knee OA patients aged 40-59 years who had a THR or TKR in the period 2004-2012. Patients who died or started on disability pension were excl
Direct cellular reprogramming has recently gained attention of cancer researchers for the possibility to convert undifferentiated cancer cells into more differentiated, postmitotic cell types. While a few studies have attempted reprogramming of glioblastoma (GBM) cells toward a neuronal fate, this approach has not yet been used to induce differentiation into other lineages and in vivo data on redu
Electrostatic interactions play crucial roles in protein function. Measuring pKa value perturbations upon complex formation or self-assembly of e.g. amyloid fibrils gives valuable information about the effect of electrostatic interactions in those processes. Site-specific pKa value determination by solution NMR spectroscopy is challenged by the high molecular weight of amyloid fibrils. Here we rep
Background: Data regarding the impact of preheart failure (HF) comorbidities on the prognosis of HF are scarce, especially in the younger HF patients. Objectives: To investigate pre-existing comorbidities in HF patients versus matched controls and to assess their impact on mortality. Methods: We included all first-time in-hospital and outpatient diagnoses of HF from 1995 to 2017, and comorbidities
Background and Purpose - Aortic valve stenosis may lead to atrial and ventricular remodeling, predisposes to atrial fibrillation, and may also be an independent risk factor of ischemic stroke. However, information on stroke rates among persons with aortic valve stenosis are sparse. We aimed to determine the incidence rates and relative risks of ischemic stroke in individuals with diagnosed aortic
There is an unmet clinical need to extract living circulating tumor cells (CTCs) for functional studies and in vitro expansion to enable drug testing and predict responses to therapy in metastatic cancer. Here, we present a novel two-step acoustophoresis (A2) method for isolation of unfixed, viable cancer cells from red blood cell (RBC) lysed whole blood. The A2 method uses an initial acoustofluid
Aim: The Cockcroft-Gault (CG) creatinine-based equation is still used to estimate glomerular filtration rate (eGFR) for drug dosage adjustment. Incorrect eGFR may lead to hazardous over- or underdosing. Methods: In a cross-sectional analysis, CG was validated against measured GFR (mGFR) in 14 804 participants and compared with the Modification-of-Diet-in-Renal-Diseases (MDRD), Chronic-Kidney-Disea
Type 2 diabetes (T2D) and non-alcoholic fatty liver disease (NAFLD) often co-occur. Defining causal pathways underlying this relationship may help optimize the prevention and treatment of both diseases. Thus, we assessed the strength and magnitude of the putative causal pathways linking dysglycemia and fatty liver, using a combination of causal inference methods.Measures of glycemia, insulin dynam
BACKGROUND: The aim of this study was to monitor blood perfusion in human upper eyelid skin flaps and examine how the perfusion is affected by the thickness of the flap.METHODS: Twenty upper eyelids were dissected as part of a blepharoplasty procedure in patients. The medial end of the blepharoplasty flap remained attached to mimic a flap design often used in reconstruction in the periocular area,
High-dose methotrexate (HDMTX) is a central component in the treatment of acute lymphoblastic leukemia, osteosarcoma, and some lymphomas and brain tumors. MTX is given at lethal doses and then is followed by rescue treatment with folinic acid (FA). Despite FA rescue, many patients suffer severe toxicity. The pharmacokinetics of FA rescue have not been sufficiently studied. However, optimization of
Two photoactive iron N-heterocyclic carbene complexes [FeII(btz)2(bpy)]2+ and [FeIII(btz)3]3+, where btz is 3,3’-dimethyl-1,1’-bis(p-tolyl)-4,4’-bis(1,2,3-triazol-5-ylidene) and bpy is 2,2’-bipyridine, have been investigated by Resonant Photoelectron Spectroscopy (RPES). Tuning the incident X-ray photon energy to match core-valence excitations provides a site specific probe of the electronic struc
Objectives: . SLE is an autoimmune disease with increased cardiovascular morbidity and platelet activation. In the general population, increased platelet size predicts platelet reactivity and cardiovascular disease. The aim of this study was to investigate whether platelet size related to platelet activation and cardiovascular disease in SLE.Methods: . Fresh blood samples from SLE patients ( n = 1
Effective communication between students and supervisors has been shown to be of importance for a high quality doctoral education by many pedagogical studies (Manathunga [1], Delamont, Aktinson and Parry [2], Halse and Malfroy [3], Bergnéher [4]). This contribution focuses on communication between supervisors and doctoral students with regard to the writing of the doctoral thesis. When it comes to
High fasting plasma concentrations of isoleucine, phenylalanine, and tyrosine have been associated with increased risk of hyperglycaemia and incidence of type 2 diabetes. Whether these associations are diet or metabolism driven is unknown. We examined how the dietary protein source affects the postprandial circulating profile of these three diabetes associated amino acids (DMAAs) and tested whethe
