Salinomycin has found renewed interest as an agent for prevention of cancer recurrence through selectively targeting cancer stem cells. Strategies for generation of improved salinomycin analogs by individual modification of its hydroxyl groups are presented. An evaluation of the dose-response effects of the resulting library on breast cancer cell lines shows that acylation of the C20 hydroxyl can
Background Limited information is available regarding genetic contributions to valvular calcification, which is an important precursor of clinical valve disease. Methods We determined genomewide associations with the presence of aortic-valve calcification (among 6942 participants) and mitral annular calcification (among 3795 participants), as detected by computed tomographic (CT) scanning; the stu
Prospective cohort studies about cutaneous melanoma (CM) risk are still few. Host factor- and UVR exposure data were collected prospectively by questionnaire in this population-based cohort study including 40000 Swedish born women, aged 25-64 years at enrolment (1990). Risk for CM (Cox regression and Stepwise Cox regression [SCR], hazard ratios [HRs] with 95 % Confidence Intervals [CI]) in relatio
INTRODUCTION: This study assessed short and long term effects of a 3-year controlled school-based physical activity (PA) intervention on fatness, cardiorespiratory fitness (VO2peak) and cardiovascular disease (CVD) risk factors in children. METHODS: The study involved 18 schools (10 intervention and 8 controls) and included a follow-up 4 years after the end of intervention. The analyses included 6
Whether cancer predisposing familial factors are associated with childhood tumors is unclear. The purpose was to study the incidence of childhood and adult tumors in extended families of children with cancer. Family history of cancer was obtained through questionnaires, and the Swedish Population-, and Cancer Registries for 194 childhood cancer patients aged ≤18 years, diagnosed 1972-2009. Standar
Abstract The majority of airborne particles in residences, when expressed as number concentrations, are generated by the residents themselves, through combustion/thermal related activities. These particles have a considerably smaller diameter than 2.5 μm and, due to the combination of their small size, chemical composition (e.g. soot) and intermittently very high concentrations, should be regard
Cancer genome sequencing has shed light on the underlying genetic aberrations that drive tumorigenesis. However, current sequencing-based strategies, which focus on a single tumor biopsy, fail to take into account intratumoral heterogeneity. To address this challenge and elucidate the evolutionary history of melanoma, we performed whole-exome and transcriptome sequencing of 41 multiple melanoma bi
Background: Epidemiological studies have indicated that physical activity reduces the risk of developing breast cancer. More recently, sedentary behavior has been suggested as a risk factor independent of physical activity level. The purpose of the present study was to investigate occupational sedentariness and breast cancer risk in pre- and postmenopausal women. Materials and methods: In a popula
In this study, aldehyde dehydrogenase 1 (ALDH1)-expressing cells in stroma of histologically normal breast tissue from premenopausal women were investigated in situ regarding cellular morphology, cell distribution, and relation to the additional stem cell markers, CD44 (+) and CD24 (-). These results were correlated with hormonal and genetic risk factors for breast cancer. Triple immunofluorescenc
The identification and validation of biomarkers for clinical applications remains an important issue for improving diagnostics and therapy in many diseases, including prostate cancer. Gene expression profiles are routinely applied to identify diagnostic and predictive biomarkers or novel targets for cancer. However, only few predictive markers identified in silico have also been validated for clin
Many microfluidic devices have been developed to separate rare cells, e.g. circulating tumor cells. The collection and analysis of the separated rare cells pose a challenge as it may lead to loss of target cells since extremely small number of cells are usually suspended in a large volume after separation. Here, we present an integrated device that allows acoustophoretic target cell separation and
The current global trade scenario has a large infrastructural gap, which limits the possibilities for physical distribution of goods among different countries or continents. The ‘Belt and Road Initiative’ will be used to close this gap. Tetra Pak being global organisation would like to explore the possibilities of using rail transport in BRI. For this reason, they would like to evaluate the benefi
Olika motiv kan influera individen till att vilja bli vegetarian, men däremot kan olika individer motiveras av olika motiv (Rosenfeld & Burrow, 2017a:85). Denna studie undersöker och behandlar följande motiv: trend-, sociala-, konsumtionskultur-, etiska- och hälsomotiv. En kvalitativ metod har tillämpats och empirin samlades in genom semistrukturerade intervjuer med vegetarianer i Sverige som
Som ett alternativ till att implementera mjukvaran in-house är det möjligt att hyra mjukvara som en tjänst, detta kallas för Software as a Service (SaaS). SaaS ställer nya krav på leverantör och kund då de ställs inför nya risker och möjligheter. Efter en litteraturgenomgång har vi identifierat dessa och funnit att vissa faktorer betraktas både som en möjlighet och risk. De faktorer som påstås
Purpose: The purpose of this thesis is to develop a theoretical framework that enables a company to measure the success of an initiative that migrates customers from one channel to another, in order to improve or upgrade the way of handling customer support between the company and its end customers. Methodology: The strategy for this thesis was to carry out an iterative case study - theory-led by
A large portion of atmospheric aerosol particles consists of secondary material produced by oxidation reactions. The relative importance of secondary organic aerosol (SOA) can increase with improved emission regulations. A relatively simple way to study potential particle formation in the atmosphere is by using oxidation flow reactors (OFRs) which simulate atmospheric ageing. Here we report on the
Androgen ablating drugs increase life expectancy in men with metastatic prostate cancer, but resistance inevitably develops. In a majority of these recurrent tumors, the androgen axis is reactivated in the form of increased androgen receptor (AR) expression. Targeting proteins that are expressed as a down-stream effect of AR activity is a promising rationale for management of this disease. The hum
The tight junction protein claudin-4 has been reported to be overexpressed in advanced ovarian cancer. We investigated the prognostic significance of claudin-4 overexpression and whether claudin-4 expression could predict platinum response in primary ovarian carcinoma (OC). Claudin-4 expression was evaluated by immunohistochemistry in a tissue microarray of 140 OCs. Multivariable Cox-regression mo
