The need for robust estimates of times of divergence is essential for downstream analyses, yet assessing this robustness is still rare. We generated a time-calibrated genus-level phylogeny of butterflies (Papilionoidea), including 994 taxa, up to 10 gene fragments and an unprecedented set of 12 fossils and 10 host-plant node calibration points. We compared marginal priors and posterior distributio
Background: Growing evidence suggests that pesticide exposure may influence respiratory health, but data in young children are very limited. We examined the association of prenatal pesticide exposure with lower respiratory tract infections (LRTIs) and wheeze at one year of age in children from the Infants' Environmental Health (ISA) study in Costa Rica. Methods: We measured seven pesticide metabol
Background: An increased knowledge of predictors that might affect survival in Alzheimer’s disease (AD) patients treated with cholinesterase inhibitors (ChEIs) is important for clinicians and for the health services. Impairment in activities of daily living (ADL), somatic diseases, and psychiatric symptoms may influence mortality in AD. We aimed to study the impact of functional capacity and conco

Knowledge about subjects who sustain hip fractures in middle age is poor. This study prospectively investigated risk factors for hip fracture in middle age and compared risk factors for cervical and trochanteric hip fractures. The Malmo Preventive Project consists of 22,444 men, mean age 44 years, and 10,902 women, mean age 50 years at inclusion. Baseline assessment included multiple examinations
Subjects with impaired glucose tolerance (IGT) are usually overweight and exhibit insulin resistance with a defective compensation of insulin secretion. In this study, we sought to establish the interrelation between insulin secretion and insulin sensitivity after oral glucose in non-obese subjects with IGT and we also examined this interrelation in relation to the 2 main incretins, glucagon-like

Gastroesofageal reThe overall aim of this thesis was to compare the effects of laparoscopic versus open antireflux surgery in a randomized clinical trial focusing the patients' subjective and objective outcome postoperatively, from a short-term and a long-term perspective. A further aim was to describe GORD patients' experiences of illness and surgical treatment and if possible to find striking characteristics rela
Popular Abstract in English This thesis presents studies on moderately halophilic bacteria belonging to the family Halomonadaceae that accumulate polyhydroxybutyrate (PHB) in high amounts when grown under conditions of nitrogen limitation.

This thesis concerns involuntary treatment of alcoholism. Clients committed according to the Swedish Act on Care of Addicts in Certain Cases were treated in the same residential treatment setting as voluntarily admitted clients. After informed consent, 104 clients (73 men and 21 women of whom 56 were compulsorily committed and 47 voluntarily admitted) participated in a test-series, including asses
Popular Abstract in English A handful of diseases-causing pathogenic microorganisms claim millions of lives worldwide each year, mainly due to limited diagnostic capabilities. The lack of simple, cost-effective, sensitive and rapid on-site diagnostic tools lead to delays in the diagnoses with a subsequent lag in treatment, which in turn can result in serious complications or even loss of lives. Fast and sensitive detection of pathogenic microbial cells is a highly important task in medical diagnostics, environmental analysis and evaluation of food safety. Accordingly, the idea of microorganism identification by the recognition of specific DNA sequence using electrochemical technique is one of the leading researches in the development of diagnostic devices. In other words, it should only
This thesis concerns a novel alkaline protease produced by an extremophilic microbial specie, designated as AL20, isolated from a feather sample collected at the shore of the alkaline soda lake Abjata in the Ethiopian Rift Valley. The isolate is a heterotrophic, alkaliphilic, halotolerant gram-positive, strictly aerobic, non-motile, non-spore forming bacterium. The organism grew at 37°C, pH 10, an
Popular Abstract in Swedish Många åtminstone i min generation kommer säkert ihåg att de under gymnasiets biologilektioner fick lära sig att vatten diffunderade fritt över cellens membran ? osmos och fri diffusion var ledorden.

In total, 238 putative PM proteins were identified, of which 114 were predicted to have transmembrane domains or to be PM-anchored. Identified proteins were involved in transport, signal transduction, membrane trafficking and stress res
#MeToo became in 2017 a strong and successful movement in Sweden where women exercised their freedom of expression to question structural injustice and men’s sexual violence against women. The movement broke the silence and stigma about being victim of men’s sexual violence and helped fight impunity. However, some of the #MeToo women in Sweden who told their stories also pointed out their perpetra
Background: Women are less likely to receive oral anticoagulation or ablation for treatment of atrial fibrillation (AF). Identification of sex differences in arrhythmia characteristics and symptoms may lead to a better understanding of potential reasons for these differences. Objectives: To determine sex differences in AF with respect to heart rate, duration, burden, and symptoms in patients under
