The question of how cooperation evolves and is maintained among nonkin is central to the biological, social, and behavioral sciences. Previous research has focused on explaining how cooperation in social dilemmas can be maintained by direct and indirect reciprocity among the participants of the social dilemma. However, in complex human societies, both modern and ancient, cooperation is frequently
Background: Nausea and vomiting in pregnancy (NVP) affects 50–80% of pregnant women and is correlated to the level of human chorionic gonadotropin (hCG). Hyperemesis gravidarum (HG) is a severe condition, with an incidence of 0.2–1.5%, characterized by consistent nausea, vomiting, weight loss and dehydration continuing after the second trimester. Aim: The aim of this systematic review was to inves
Anterior cruciate ligament (ACL) injury rates in female adolescents are increasing. Irrespective of treatment options, approximately 1/3 will suffer secondary ACL injuries following their return to activity (RTA). Despite this, there are no evidence-informed RTA guidelines to aid clinicians in deciding when this should occur. The first step towards these guidelines is to identify relevant and feas
Systemic lupus erythematosus (SLE) is an autoimmune disease involving many organ systems. The cause is not known, but a complex combination of environmental and genetic factors seems to be involved. In SLE upregulation of type I interferons, a hyperactive B-cell response, presence of autoantibodies against modified nuclear components, increased complement consumption, increased apoptosis and decre
Selective immunoglobulin A deficiency is the most common primary immunodeficiency disorder that is strongly overrepresented among patients with celiac disease (CD). IgG antibodies against tissue transglutaminase (tTG) and deamidated gliadin peptides (DGP) serve as serological markers for CD in IgA deficient individuals, although the diagnostic value remains uncertain. The aim of this study was to
Uppsatsens syfte har varit att kritiskt granska den svenska debatten kring DNA-analys för asylsökande barns rätt till familjeåterförening i Sverige och därmed se ifall principen om barnets bästa, definierat i svenska rättsakter, efterföljs. Genom den vägledande domen från Migrationsöverdomstolen den 18 januari 2012 fastslogs att DNA-analys kan användas för att styrka biologiskt släktskap med förälThe aim of this thesis has been to do a critical review on the Swedish debate concerning the use of DNA-tests to secure the rights of asylum-seeking children to be reunited with their families and if the principle of the best interests of the child is followed. The 18th of January 2012, in a precedent ruling, the Swedish Migration Court of Appeal concluded that DNA-test could be used to prove biol
Under många år har diskussioner förts kring upprättandet av en enhetlig europeisk avtalsrättslig lagstiftning. Harmoniseringsprocessen har pågått såväl på lagstiftningsplanet som på akademisk nivå. Draft Common Frame of Reference, DCFR, initierades som ytterligare ett steg mot denna tillnärmning av lagstiftning. Nämnda referensram utgör hittills soft law men kan, helt eller delvis, komma att liggaFor several years, there has been an ongoing debate regarding the establishment of a uniform European contract law. The subsequent harmonization process has been driven both on an academic level as well as by the legislative authority of the European Union. Recently established, the Draft Common Frame of Reference, DCFR, is an initial step towards unification of laws. This frame of reference is hi
Monoclonal antibodies are among the most promising therapeutic agents in modern medicine, yet their formulation into high-concentration solutions for subcutaneous self-administration poses a major challenge. A key obstacle is the marked increase in viscosity often observed under these conditions. To gain deeper insights into this phenomenon, coarse-grained models derived from soft matter physics h
It is now established that native language affects one's perception of the world. However, it is unknown whether this effect is merely driven by conscious, language-based evaluation of the environment or whether it reflects fundamental differences in perceptual processing between individuals speaking different languages. Using brain potentials, we demonstrate that the existence in Greek of 2 color
Insulin-independent diabetes mellitus is often accompanied by manifestations of autoimmunity and is frequently associated with certain HLA haplotypes, predominantly DR3 and DR4. Because the major histocompatibility antigens are important determinants of the immune response in various tissues, we have investigated their expression on the pancreatic islet cells. Human, mouse, or rat islets of Langer
The role of auditory feedback in vocal production has mainly been investigated by altered auditory feedback (AAF) in real time. In response, speakers compensate by shifting their speech output in the opposite direction. Current theory suggests this is caused by a mismatch between expected and observed feedback. A methodological issue is the difficulty to fully isolate the speaker’s hearing so that
How did human symbolic behavior evolve? Dating up to about 100,000 y ago, the engraved ochre and ostrich eggshell fragments from the South African Blombos Cave and Diepkloof Rock Shelter provide a unique window into presumed early symbolic traditions of Homo sapiens and how they evolved over a period of more than 30,000 y. Using the engravings as stimuli, we report five experiments which suggest t
Background: Mild induced hypothermia (MIH) was introduced for post cardiac arrest care in Sweden in 2003, based on two clinical trials. This retrospective study evaluated its association with 30-day survival after out-of-hospital cardiac arrest (OHCA) in a Swedish community from 2003 to 2015. Methods: Out of 3680 patients with OHCA, 1100 were hospitalized after return of spontaneous circulation an
Medellivslängden ökar och är idag över 80 år i 34 av världens länder, jämfört med i 19 länder år 2005. Detta ärpositivt, men den åldrande befolkningens hälsa är också en samhällsutmaning inte minst för välfärdssystemen.Hälso- och sjukvården riskerar blir särskilt belastad med allt fler vårdsökande äldre. Yrkesgrupperna inom hälsoochsjukvården har dessutom en hög medelålder och är samtidigt bland d
Solvents are commonly used in pharmaceutical and cosmetic formulations and sanitary products and cleansers. The uptake of solvent into the skin may change the molecular organization of skin lipids and proteins, which may in turn alter the protective skin barrier function. We herein examine the molecular effects of 10 different solvents on the outermost layer of skin, the stratum corneum (SC), usin
Purpose: Elevated copeptin, a vasopressin marker, is linked to metabolic disease, and obese rats with low-vasopressin concentration had a decreased risk of liver steatosis. We here investigated the association between copeptin and nonalcoholic fatty liver disease (NAFLD) and possible differences in copeptin concentration between ethnicities. Methods: In this cross-sectional study of 361 South Afri
Lanthipeptides are ribosomally synthesized and post-translationally modified polycyclic peptides. Lanthipeptides that have antimicrobial activity are known as lantibiotics. Accordingly, the discovery of novel lantibiotics constitutes a possible solution for the problem of antibiotic resistance. We utilized the publicly available genome sequences and the bioinformatic tools tailored for the detecti
The study makes an inventory of learning opportunities young people were offered in connection with CEI 2016, one of the annual international conferences organized by the NGO named Caretakers of the Environment International (CEI), which year 2016 took place in Aalborg in Denmark. The learning opportunities offered by this transnational learning community are discussed in relation to some essenti
A large literature documents how intergenerational mobility—the degree to which (dis)advantage is passed on from parents to children—varies across and within countries. Less is known about the origin or persistence of such differences. We show that US areas populated by descendants to European immigrants have similar levels of income equality and mobility as the countries their forebears came from
During 2012 - 2013 a study to evaluate conventional X-ray procedures and patient doses in Klintzi and Novozibkov areas of Bryansk region, Russia, was conducted. X-ray operation parameters included quality assurance of equipment, collection of procedure parameters and clinical practice evaluation. Effective doses were calculated for each selected procedure and dose distributions were established. 7
