Denna uppsats är skriven vid institutionen för kommunikation och medier vid Lunds Universitet. Den författades av Jakob Lundgren och Adam Mattebo under ämnet media- och kommunikationsvetenskap och den är skriven på en B-nivå. Uppsatsens syfte var att undersöka om användandet av mobilapplikationen Snapchat, som växt väldigt snabbt de senaste åren, skiljde sig åt från andra sociala medier. Uppsatsen
Germline mutations in the tumour suppressor gene CDKN2A occur in 5-20% of familial melanoma cases. A single founder mutation, p.Arg112dup, accounts for the majority of CDKN2A mutations in Swedish carriers. In a national program, carriers of p.Arg112dup mutation have been identified. The aim of this study was to assess cancer risks in p.Arg112dup carriers and their first degree relatives (FDRs) and
The public health impact of population-based mammography screening programs depends on high participation rates. Thus, monitoring participation rates, as well as understanding and considering the factors influencing attendance, is important. With the goal to acquire information on the appropriate level of intervention for increasing screening participation our study aimed to (1) examine whether, o
I denna uppsats undersöks hur musiker upplever de förändringar som skett i musikbranschen de senaste tio åren till följd av den tekniska utvecklingen i form av bland annat gratisteknologier, exempelvis Spotify och Myspace, samt fildelning. I undersökningen har kvalitativa metoder i form av intervjuer använts. Vi har utgått från ett antal teoretiska begrepp som exempelvis medielogik, mediekonvergen

Most clinical studies use conventional methods for survival analysis and calculate the risk of the event of interest, however, it is important to understand that the study population is also at risk of competing events, for example death from other causes. Moreover, the risk of competing events may be dependent on the participants' characteristics. Whether competing risks are taken into account or
Stroke is a leading cause of disability and currently lacks effective therapy enabling long-term functional recovery. Ischemic brain injury causes local inflammation, which involves both activated resident microglia and infiltrating immune cells, including monocytes. Monocyte-derived macrophages (MDMs) exhibit a high degree of functional plasticity. Here, we determined the role of MDMs in longterm
Background: Approximately 180 mothers are treated in Swedish Intensive Care Units (ICU) due to preeclampsia each year. Although several clinical risk factors are known, prediction of critical disease is challenging. Two scavenger proteins, hemopexin (Hpx) and alpha-1-microglobulin (A1M) have been suggested to be associated with the oxidative stress seen in preeclampsia. The ratio of two other biom
We present new estimates of the living standards among the rural labouring classes in Sweden from 1750 to 1900. Starting with a database of more than 1,000 probate inventories of rural, landless and semi-landless people from the years 1750, 1800, 1850 and 1900, we study the development for crofters in particular. In a sub-sample of 120 probate inventories we map in great detail the material items
Selective Serotonin Reuptake Inhibitors (SSRIs) may hold therapeutic benefits for people with Alzheimer’s disease (AD). SSRIs may perturb AD progression, or the conversion from MCI to AD, via increased neurogenesis, reduced oxidative stress and/or favourable Amyloid-β Precursor Protein (AβPP) processing. This study used iPSC derived cortical neuronal cells carrying 3 different PSEN1 mutations, to
Increasing human impact on the environment is causing drastic changes in disturbance regimes and how they prevail over time. Of increasing relevance is to further our understanding on biological responses to pulse disturbances (short duration) and how they interact with other ongoing press disturbances (constantly present). Because the temporal and spatial contexts of single experiments often limi
Background: Patients with hand eczema often describe symptoms such as pain, clumsiness and difficulty flexing their fingers, thus impairing the function of the hand. Objective: The aim of this study was to investigate whether hand eczema is associated with a measurable impairment of hand strength and dexterity. We also studied the relationship between hand function and the ability to perform activ
Differences in migratory behavior have been suggested to drive speciation, but the genetics underlying this process remain unknown. Identification and study of migratory divides can help us understand how differential migration can lead to reproductive isolation. Here, we genotyped Willow Warblers Phylloscopus trochilus, from the Åland islands, located in between the ranges of the differentially m
Background. Epidemiological studies indicate that physical activity reduces the risk of cancer. Physical inactivity or sedentary behavior, has recently been suggested as a risk factor independent of physical activity level. Breast and endometrial cancer incidence have both been associated with physical activity, and endometrial cancer incidence with physical inactivity/sedentary behavior. The purp
Habitat loss and population fragmentation pose severe threats to biodiversity and the survival of many species. Population isolation and the decline in effective population size lead to increased genetic drift and inbreeding. In turn, this reduces neutral diversity, and it also affects the genetic load of deleterious mutations. Here, we analyse the effect of such genomic erosion by designing a spa
BACKGROUND: Contact allergy rates of linalool and limonene hydroperoxides (HPs) have increased.OBJECTIVES: To demonstrate the patterns of simultaneous positive patch test (PT) reactions and prevalences of multiple contact allergies (MCAs) in patients with contact allergy to linalool and/or limonene HPs.METHODS: A retrospective analysis of consecutive dermatitis patients in 2015-2020 was performed.
BackgroundCurrent guidelines from Scandinavian Neuro Committee mandate a 24-hour observation for head trauma patients on anticoagulants, even with normal initial head CT scans, as a means not to miss delayed intracranial hemorrhages. This study aimed to assess the prevalence, and time to diagnosis, of clinically relevant delayed intracranial hemorrhage in head trauma patients treated with oral ant
OBJECTIVES: To investigate if the sport concussion assessment tool version 5 (SCAT5) could be suitable for application to Para athletes with a visual impairment, a spinal cord injury, or a limb deficiency.METHODS: A 16-member expert panel performed a Delphi technique protocol. The first round encompassed an open-ended questionnaire, with round 2 onwards being composed of a series of closed-ended s
