Titel: Influerad av influencers. Universitet och program: Lunds Universitet, Campus Helsingborg. Service Management, Retail. Författare: Michaela Eliasson & Sandra Waldt Handledare: Åsa Friberg Problemområde: Under 2016 ägnade sig unga individer cirka sex timmar om dagen på sociala medier, däribland Instagram, som är en av de mest dominerande sociala medier-plattformarna. Sociala medier har

Bakgrund: Fysisk aktivitet i klassrummet har visat sig ge ökat fokus och förbättrar skolresultat bland elever. Att ägna en kort stund av lektionstiden åt fysisk aktivitet minskar också stillasittandet och dess negativa effekter, där så lite som två minuter är tillräckligt. Syfte: Syftet med denna studie var att kartlägga integreringen av fysisk aktivitet under lektionstid för att minska stillasitt

Objectives: To understand the comparability of serum prostate-specific antigen (PSA) determinations across assays and storage time. Methods: Serum PSA levels were determined for men aged 40 to 79 years from the clinical subset of the Olmsted County Study of Urinary Symptoms and Health Status Among Men on fresh samples and after a median of 32 months on banked samples, frozen at -70 °C. Baseline se

Objectives. Nearly half of men with clinically localized prostate cancer are understaged. We evaluated whether knowledge of preoperative free prostate-specific antigen (f-PSA), complexed (c-PSA), and total (t-PSA) concentrations or the ratios thereof (f-PSA/t-PSA, c-PSA/t PSA, and f PSA/c- PSA) could improve upon the staging of prostate cancer when compared with standard PSA testing (t-PSA). In ad

Sedimentary molybdenum (Mo) and uranium (U) enrichments are widely used to reconstruct changes in bottom water oxygen conditions in aquatic environments. Until now, most studies using Mo and U have focused on restricted suboxic-euxinic basins and continental margin oxygen minimum zones (OMZs), leaving mildly reducing and oxic (but eutrophic) coastal depositional environments vastly understudied. C

Childhood is a period of extensive cortical and neural development. Among other things, axons in the brain gradually become more myelinated, promoting the propagation of electrical sig-nals between different parts of the brain, which in turn may facilitate skill development. Myelin is difficult to assess in vivo, and measurement techniques are only just beginning to make their way into standard im

Local tumor-associated immune cells hold prognostic and predictive value in various forms of malignancy. The role of systemic, circulating leukocytes is, however, not well-characterized. In this prospective and explorative study, we aim to delineate the clinical relevance of a broad panel of circulating immune cells in 32 patients with newly diagnosed metastatic breast cancer (MBC) before the star

PurposeArterial stiffness is independently associated with orthostatic hypotension in older individuals. The relationship between orthostatic blood pressure adaptation and aortic stiffness has not been thoroughly examined in a younger population. We investigated the relationship between orthostatic blood pressure adaptations, central aortic hemodynamics, and aortic stiffness in a cohort of predomi

BACKGROUND: Emergency computed tomography angiography (CTA) is the most important imaging modality to visualize arterial occlusions in patients with acute lower limb ischaemia (ALI). Extravascular incidental findings (EVIFs) have received less attention.PURPOSE: The aims of this study were to evaluate the incidence of EVIFs of immediate clinical relevance in patients with ALI undergoing CTA and ev

An acoustofluidic device, consisting of a polymer chip with a long straight channel, coupled to a piezoelectric transducer is modeled numerically in three dimensions and compared to experimental results in terms of the electric admittance as well as the ability to focus particles. In our experiments we obtain good acoustic particle focusing at a frequency of f = 1.14 MHz with an actuation voltage

Purpose: To assess the feasibility of characterizing gene copy number alteration by fluorescence in situ hybridization (FISH) of circulating tumor cells (CTC) isolated using the Cell Search system in patients with progressive castration-resistant metastatic prostate cancer. Experimental Design: We used probe combinations that included the androgen receptor (AR)and MYC genes for FISH analysis of CT

This chapter takes the fall of the Berlin Wall as its point of departure, and from there it traces a trajectory of unforeseen developments that have led from the erstwhile global optimism to the dramatic shift in mood just three short decades later. The key questions posed are: What global developments that were unforeseen then can account for the much more sombre ambience, pessimism or even alarm

We have constructed two phagemid vectors containing the gene coding for human Prostate Specific Antigen (PSA) translationally fused to a pelB signal sequence and minor coat protein III of phage fd leading to phage particles that carry PSA on their tips. Phages were characterized by Western blotting and by panning, using biotinylated monoclonal anti-PSA antibodies immobilized onto streptavidin-coat

Background. Prostate specific antigen (PSA) is a zymogen of a 33‐kilodalton (kD) serine proteinase with extensive similarity to glandular kallikreins. The mechanism responsible for converting the zymogen into active proteinase has not been defined, but active PSA may be irreversibly inactivated in vitro by two of the major proteinase inhibitors in blood: alpha1‐antichymotrypsin and alpha2‐macroglo

Summary Prostatic acid phosphatase (PAP), prostate‐specific antigen (PSA; or γ‐seminoprotein), and β‐microseminoprotein (β‐MSP; PSP94 or β‐inhibin) are the three predominant proteins secreted by the normal human prostate gland. In the epithelium of normal and hyperplastic prostatic acini and ducts PAP, PSA and β‐MSP have an identical immunohistochemical localization. Highly differentiated (grade I

Serum γ-glutamyltransferase (EC 2.3.2.2) showed microheterogeneity on electrofocusing, owing to variations in sialic acid content. We investigated the isoform patterns of papain-treated serum samples on agarose gels containing nonionic detergent and ampholytes in the low pH range. Serum from cases of cholestasis show seven bands with γ-glutamyltransferase activity. These same bands were also found

From liquefied human seminal plasma, we purified the predominant basic protein which appears following liquefaction of coagulated semen. The protein was purified in the presence of di-isopropylfluorophosphate to retard its degradation. Heparin-Sepharose® chromatography was followed by gel filtration (Biogel® P 60) and by fast performance liquid chromatography on a reversed phase column (C8). The b

Decarbonizing society will require a shift toward renewable electricity production. However, the temporal configuration of renewables requires that demand adapt accordingly. Introducing intermittent electricity production will thus require end users to be more flexible in their use of electricity. Flexibility capital has been promoted as a concept for analyzing material preconditions in order to u
