This work presents a simple method for obtaining homogeneous sample surfaces in matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI-TOFMS) for the automated analysis of peptides and proteins. The sample preparation method is based on applying the sample/matrix mixture onto a pre-deposited highly diluted matrix spot. The pre-deposited crystals act as seeds for the ne
Cisplatin is one of the most effective chemotherapy drugs and is widely used in the treatment of cancer, including hepatocellular carcinoma (HCC) and cervical cancer, but its therapeutic benefit is limited by the development of resistance. Our previous studies demonstrated that BCAT1 promoted cell proliferation and decreased cisplatin sensitivity in HCC cells. However, the exact role and mechanism
Lenalidomide, an antineoplastic and immunomodulatory drug, has therapeutic activity in acute myeloid leukemia (AML), but definitive studies about its therapeutic utility have been lacking. In a phase 3 study, we compared 2 induction regimens in newly diagnosed patients age 18 to 65 years with AML: Idarubicine-cytarabine (cycle 1) and daunorubicin and intermediate-dose cytarabine (cycle 2)without o
Objectives:The overall aim of the dissertation is to examine antibody response to immunization with pneumococcal vaccine in patients with inflammatory rheumatic disease (IRD), in relation to disease-modifying antirheumatic drug (DMARD) treatments, and in postsplenectomy patients.Methods:(I) Splenectomized patients without previous pneumococcal conjugate vaccine (PCV) immunization were invited to r
An organogel was prepared by chemically cross-linking a poly(styrene-block-4-vinylpyridine) diblock copolymer using dibromododecane in dimethylformamide. Analysis of the prominent structure peak in small-angle X-ray scattering along with the results of light scattering and rheological profile suggests the bridging of the spherical micelles to one another to form an interconnected network after gel
Glycobiology is dogged by the relative scarcity of synthetic, defined oligosaccharides. Enzyme-catalysed glycosylation using glycoside hydrolases is feasible but is hampered by the innate hydrolytic activity of these enzymes. Protein engineering is useful to remedy this, but it usually requires prior structural knowledge of the target enzyme, and/or relies on extensive, time-consuming screening an
The role of breast oedema in breast reconstruction is unknown. Therefore, our aim was to investigate local tissue water (LTW) and breast oedema-related symptoms in breasts reconstructed with either an expander prosthesis (EP) or with a deep inferior epigastric perforator (DIEP) flap at a minimum of one year postoperatively. Sixty-eight patients randomised to breast reconstruction with an EP or DIE
We investigate the viability of observing charged Higgs bosons ( H± ) produced in association with W bosons at the CERN large hadron collider, using the leptonic decay H+ → + ν τ and hadronic W decay, within different scenarios of the minimal supersymmetric standard model (MSSM) with both real and complex parameters. Performing a parton level study we show how the irreducible standard model backgr
Achieving quantum confinement by bottom-up growth of nanowires has so far been limited to the ability of obtaining stable metal droplets of radii around 10 nm or less. This is within reach for gold-assisted growth. Because of the necessity to maintain the group III droplets during growth, direct synthesis of quantum sized structures becomes much more challenging for self-assisted III-V nanowires.
Background: To our knowledge there is no report in the literature on measurements of vertebral rotation with low-dose computed tomography (CT) in prone position.Aims: To describe and test the reliability of this new method, compare it with other methods in use and evaluate the influence of body position on the degree of vertebral rotation measured by different radiological methods.Study design: Re
Acute leukemia, myelodysplastic syndromes (MDS), myeloproliferative neoplasms and lymphomas are the most prevalent diagnoses in adults presenting with new onset cytopenia. Here, we describe two 10-color panels of surface markers (screening and comprehensive panel) applied at the Flow Cytometry Laboratory, University Health Network, Toronto, ON, Canada. A 10-color flow cytometry is applied using th
Intravesical inoculation of gram negative bacteria or isolated bacterial products into mice induces an IL-6 response which can be measured within miutes of the infection.1,2 In such infections, IL-6 is initially detected in the urine and subsequently in the serum. Similar IL-6 responses were found in human patients deliberately colonized in the urinary tract with E. coli Hu7343. IL-6 was secreted
Objective: To assess and compare the accuracy of imaging methods (ultrasonography (US), computed tomography (CT), angiography, arterially enhanced CT with computed tomographic arterial portography (CTA)), biochemical analyses, and surgical assessment during the operation, in detecting the presence or absence of hepatic metastases in patients with colorectal cancer. Design: Open study. Setting: Uni
Background : Colorectal cancer (CRC) is considered one of the most common forms of cancer in the Western world. High intake of red and processed meat is considered to increase CRC development. Objective : This study examined associations between intake of red meats, poultry, and fish and incident CRC, and if weight status modifies the associations. Design : In the Malmö Diet and Cancer Study, diet
The demographic changes in society with growing numbers of elderly subjects will inevitably increase admission rates to acute emergency departments (AMU). Early discharge might augment emergency readmissions due to a relapse in medical conditions. Our aim was to study precipitating factors in frail elderly patients who got the diagnosis 'lack of community support' after initial medical examination
Lipases were investigated with respect to their ability to catalyse the incorporation of fatty acids into phosphatidylcholine (PC) by interesterification reactions. The enzymes were dried onto solid support materials and the conversions were carried out in water-saturated toluene. Three lipases (two fungal and one plant enzyme) had the desired activity; immobilized lipase from Mucor miehei (Lipozy
Hymns to Unknown Heroines part III – Elna, 2015 Slide and sound installationHymns to Unknown Heroines, part III is the latest iteration of a multifaceted work. The starting point was an anonymous photographic archive from the 1920s that depicts a Scottish family over several years. Many of the photographs portray women engaged in recreational activities, portraying an undemanding lifestyle that ca
Objective: The aim of this study was to clarify the role of ‘contagion’, or social transmission, in risk of suicidal behaviour (SB) among siblings. Methods: We followed Swedish sibling pairs until one of them (S1; N = 111,848) was registered for a suicide attempt or completion. We tested the effect of geographic proximity between siblings on risk of a first SB registration of S1's sibling (S2). To
Direct numerical simulations (DNS) of statistically planar flames at moderate and high Karlovitz number (Ka) have been used to perform an a priori evaluation of a presumed-PDF model approach for filtered reaction rate in the framework of large eddy simulation (LES) for different LES filter sizes. The model is statistical and uses a presumed shape, based here on a beta-distribution, for the sub-gri
