Peer Assisted Study Sessions (SI-PASS) in Higher Education, a European overview

The paper/presentation gives an overview of Peer-Assisted Study Schemes (SI-PASS) in Higher Education in Europe. SI-PASS is a method of improving student performance in “difficult” courses combining “how to learn” with “what to learn”. SI-PASS sessions are scheduled parallel to the regular education and are guided and facilitated by a “senior” student, the SI-PASS leader. The sessions are based on

What intent, whose intent and to what extent?: The Knowledge requirement in indirect patent infringement

In Germany, the UK, the US and the Scandinavian countries there is a distinct difference between direct and indirect (also referred to as contributory) statutory patent infringement. The patent laws that regulate incursions on the exclusive rights of patent holders in these jurisdictions generally distinguish between direct patent infringement on the one hand, which is based on wholly objective cr

Epigenetic Mapping in Type 2 Diabetes. Glucose-triggered histone modifications in various tissues

Epigenetic modifications triggered by high glucose may predispose to diabetes risk by regulating gene expression activity. A growing body of evidence suggests that histone modification which is an essential component of epigenetic mechanism may play an important role in the development of type 2 diabetes (T2D) and its complications. In this thesis, the overarching aim is to map histone modificatio

Helicobacter pylori screening in clinical routine during hospitalization for acute myocardial infarction

Background: Potent antithrombotic therapy has significantly improved prognosis for patients with acute myocardial infarction (AMI), however, at a price of increased bleeding risk. Chronic gastric infection with Helicobacter pylori (Hp) commonly causes upper gastrointestinal bleeding and is proposed as a risk factor for subsequent bleeding post AMI. The prevalence of active Hp in a current AMI popu

Extracellular matrix in atherosclerotic plaques: its role in plaque stability

Atherosclerosis is a systemic disease affecting the large arteries caused by the accumulation of lipids in the vessel wall. Cardiovascular disease due to atherosclerosis is today the most common cause of death globally through its end consequences: myocardial infarctions and stroke. The extracellular matrix (ECM) is a network of structural fibrous proteins, proteoglycans and glycoproteins. ECM pro

Detecting COVID-19 infection hotspots in England using large-scale self-reported data from a mobile application : a prospective, observational study

Background: As many countries seek to slow the spread of COVID-19 without reimposing national restrictions, it has become important to track the disease at a local level to identify areas in need of targeted intervention. Methods: In this prospective, observational study, we did modelling using longitudinal, self-reported data from users of the COVID Symptom Study app in England between March 24,

The accumulation rate of tau aggregates is higher in females and younger amyloid-positive subjects

The development of tau-PET allows paired helical filament tau pathology to be visualized in vivo. Increased knowledge about conditions affecting the rate of tau accumulation could guide the development of therapies halting the progression of Alzheimer's disease. However, the factors modifying the rate of tau accumulation over time in Alzheimer's disease are still largely unknown. Large-scale longi

Elucidating Genetic and Biochemical Aspects of the P1 and Sda Carbohydrate Histo-Blood Group Antigens

Human histo-blood groups are inherited polymorphic variants that occur in the molecular structures on the humanred blood cell (RBC) surface. Introducing foreign RBCs into a recipient lacking an antigen may activate the humoraldefence leading to a hemolytic transfusion reaction. Antigenic differences can also cause hemolytic disease of thefetus and newborn (HDFN). Blood group antigens are implicate

Infertility, pregnancy loss and assisted reproduction in women with asthma : a population-based cohort study

STUDY QUESTION: Is the chance of childbirth, and risk of infertility, pregnancy loss and need for assisted reproduction different for women with asthma compared to women without asthma?SUMMARY ANSWER: Women with asthma had comparable chances of giving birth compared to the reference population, however, their risk of both infertility and pregnancy loss, as well their need for medically assisted re

PM 2/21 : Methods for assessing the effects of plant protection products on biodiversity

Lunds universitet fick i uppdrag av Kemikalieinspektionen att kartlägga och beskriva ansatser till metoder som bedömer indirekta effekter av växtskyddsmedel på individer och populationer och studier som utvärderar om nuvarande riskbedömningsmetoder är tillräckliga för att bedöma direkta effekter av växtskyddsmedel på biologisk mångfald. Uppdraget utfördes i två delar. För det första inventerade vi

Molecular Mechanisms of Graves' Ophthalmopathy. A focus on smoking and radioiodine.

Graves’ disease (GD) is an autoimmune disease characterized by hyperthyroidism and is caused by an interplayof genetic and environmental factors. One-third of patients with GD develop Graves’ ophthalmopathy (GO). Keyprocesses in the pathogenesis of GO are inflammation and adipogenesis in orbital tissue. Strong risk factorsassociated with the development of GO are smoking and radioiodine treatment

Carbon exchange in boreal ecosystems: upscaling and the impacts of natural disturbances

Boreal forests and peatlands are globally significant carbon stores but they are threatened by rising air temperatures and changes in precipitation regimes and the frequency of natural disturbances. Predicting how the boreal biome will respond to climate change depends on being able to accurately model and upscale the greenhouse gas fluxes between these ecosystems and the atmosphere. This thesis f

Identification of vulnerable plaques and patients by intracoronary near-infrared spectroscopy and ultrasound (PROSPECT II) : a prospective natural history study

Background: Near-infrared spectroscopy (NIRS) and intravascular ultrasound are promising imaging modalities to identify non-obstructive plaques likely to cause coronary-related events. We aimed to assess whether combined NIRS and intravascular ultrasound can identify high-risk plaques and patients that are at risk for future major adverse cardiac events (MACEs). Methods: PROSPECT II is an investig

Measures of cortical microstructure are linked to amyloid pathology in Alzheimer's disease

Markers of downstream events are a key component of clinical trials of disease-modifying therapies for Alzheimer's disease. Morphological metrics like cortical thickness are established measures of atrophy but are not sensitive enough to detect amyloid-beta (Aβ)- related changes that occur before overt atrophy become visible. We aimed to investigate to what extent diffusion MRI can provide sensiti

Roles of unconventional ion channels and insulin granule structure in the pathogenesis of type-2 diabetes

T2D is the most widespread endocrine disease. In conventional stimulus secretion coupling increased blood glucose is metabolized causing an increased intracellular level of ATP and closure of the KATP channels, and this, in turn, depolarizes the cell membrane leading to the opening of voltage-gated Ca2+ channels, the influx of Ca2+ and exocytosis of insulin granules. This model has become almost a

Participation in prospective studies of children with high risk for type 1 diabetes. Psychological effects, experience, and study compliance

AbstractAim: The overall aim of the thesis was to examine the psychosocial effects and family reactions to participation in longitudinal studies with their children at high risk for type 1 diabetes. Additionally, we aimed to develop a shorter form for the children to measure their anxiety when thinking of their risk of developing type 1 diabetes, which could be used in The Environmental Determinan

Mitigating a social conflict between seal, conservation and fisheries in the Baltic Sea : multilevel and synergistic approaches

The conflict between seal conservation and fisheries in the Baltic Sea has becomeremarkably serious and threatens the existence of coastal fishing activities in theBaltic Sea. Seals cause significant catch losses, gear damage and various types ofhidden damages and losses. In particular, reports of damage caused by the grey seal,the largest and most common seal species in the Baltic Sea, have incre

Noninvasive Staging of Lymph Node Status in Breast Cancer Using Machine Learning : External Validation and Further Model Development

Background: Most patients diagnosed with breast cancer present with a node-negative disease. Sentinel lymph node biopsy (SLNB) is routinely used for axillary staging, leaving patients with healthy axillary lymph nodes without therapeutic effects but at risk of morbidities from the intervention. Numerous studies have developed nodal status prediction models for noninvasive axillary staging using po

The mid-Ordovician meteorite flux to Earth shortly before breakup of the L-chondrite parent body

The breakup of the L-chondrite parent body (LCPB) in the asteroid belt at 466 Ma ago is the largest asteroid breakup documented in Earth's geological record for the past ca. three billion years. Recovery of abundant macroscopic fossil L chondrites in mid-Ordovician marine sediments as well as reconstructions of the flux of micrometeoritic chrome spinel through the ages have given much new informat
