1. Theory predicts that the processes generating biodiversity after disturbance will change during succession. Comparisons of phylogenetic and functional (alpha and beta) diversity with taxonomic diversity can provide insights into the extent to which community assembly is driven by deterministic or stochastic processes, but comparative approaches have yet to be applied to successional systems. 2.
Long-term oxygen therapy (LTOT) improves the survival time in hypoxemic chronic obstructive pulmonary disease. Despite warnings about potential dangers, a considerable number of patients continue to smoke while on LTOT. The incidence of burn injuries related to LTOT is unknown. The aim of this study was to estimate the rate of burn injury requiring health care contact during LTOT.
Introduction: Prenatal exposure to inflammatory states has been suggested to influence offspring neurodevelopment. The aim was to investigate if offspring exposure to maternal Inflammatory bowel disorder (IBD), or specifically the IBD disorder Crohn's disease, during gestation is associated with neurodevelopmental or psychiatric disorders in childhood. Material and Methods: We conducted a populati
The combustion of aluminum powder enables a CO2-free generation of heat and electricity. To understand the asymmetric combustion of burning aluminum particles, we imaged light extinction and scattering with high speed and magnification. In the flame, particles melt, ignite, and build up a spherical flame sheet of condensed-phase alumina around the droplet. Shortly thereafter, the asymmetric stage
Marine environments worldwide are increasingly threatened by warming, deoxygenation, and ocean acidification. These stressors can be recorded as alterations in foraminiferal geochemistry and morphology. We integrated morphological features with assemblage and geochemical records of benthic foraminifera from the Danish Straits at the entrance to the Baltic Sea, covering the Last Interglacial period
The precuneus is a site of early amyloid-beta (Aβ) accumulation. Previous cross-sectional studies reported increased precuneus fMRI activity in older adults with mild cognitive deficits or elevated Aβ. However, longitudinal studies in early Alzheimer’s disease (AD) are lacking and the relationship to the Apolipoprotein-E (APOE) genotype is unclear. Investigating the PREVENT-AD dataset, we assessed
Introduction: The pulmonary oxygen uptake is reduced during apnea, compared to eupneic baseline, preserving the pulmonary oxygen store. This study elucidates the time course for this reduction, comparing it to the time course for apnea-induced cardiovascular responses. Methods and results: Experiments involved two groups, performing apneas during rest, both without and with cold-water face immersi
Objectives: Adverse pregnancy outcomes are more common in women with SLE compared with healthy women, but we lack prognostic biomarkers. Plasma IFN-α protein levels are elevated in a subgroup of pregnant women with SLE, but whether this is associated with pregnancy outcomes is unknown. We investigated the relationship between IFN-α, adverse pregnancy outcomes and the presence of autoantibodies in
In post-bureaucratic organizations, coworkers have progressively acquired more importance in decision-making and strategy processes and, simultaneously, are expected to perform new communicative roles. Yet, there is a strong managerial focus in organizational communication research that has overlooked the role of coworkers as communicators, and the studies that have focused on the topic have empha
Covid19 pandemin har inneburit stora utmaningar för psykisk hälsa globalt, dels på grund av begränsningar som införts för att minska smittspridningen såsom social distansering, men också rädslan som följer att leva under oroliga tider. Tidigare studier har bidragit till förklaringar av covid19’s effekter på psykisk hälsa genom att fokusera på antingen personlighetsbaserade eller kontextuella faktoThe covid19 pandemic has presented great challenges to mental health globally, in part due to restrictions implemented in the wake of the pandemic; such as social distancing, but also due to the fear and psychological distress associated with living during times of crisis. Prior studies have contributed to explaining covid19’s effects on mental health by addressing either personality-based or cont
Background: A knee-medial-to foot position (KMFP) during functional tasks has been identified as a risk factor for Anterior cruciate ligament (ACL) -injury among women. Among ACLinjured subjects, a reduced sensory and proprioceptive function has been correlated with a KMFP during functional tasks. The most reliable measure of proprioception seems to be the measuring of a subject’s Threshold to Det
It has become more important for people worldwide to eat and drink products that offer us health- promoting benefits, which traditional foods do not possess. These kinds of products are called functional foods and have been fortified using vitamins, minerals or probiotics among others. Today, there are a lot of probiotic strains on the market and the first part of the aim of this study was to eval
During the last century, an increasingly sedentary lifestyle has emerged in modern societies. A lack of exercise is detrimental to global health and physical inactivity is now according to the World Health Organization the fourth leading risk factor for premature mortality. Physical inactivity is associated with increased risk of developing chronic diseases such as diabetes, cardiovascular disease
BACKGROUND: Hemostatic disorders are common in obstetric complications. Thromboelastography (TEG (R)) simultaneously measures coagulation and fibrinolysis within 10 to 20 minutes. Our primary aim in this prospective longitudinal study was to obtain knowledge about physiological changes in TEG (R) variables during normal pregnancy and 8 weeks postpartum. The secondary aims were to compare TEG (R) v
Objective: To evaluate the effects of eccentric isokinetic training on knee range of motion (ROM) of healthy subjects. Methods: The knee extensor and flexor isokinetic peak torques and ROM of flexion/extension and varus/valgus knee movements during gait of 18 healthy men (21.7 +/- 2.2 years; 1.73 +/- 0.10m; 68.7 +/- 9.4kg; body mass index: 22.6 +/- 2 kg/m(2)) were analyzed, before and after six we
The aim of the study was to explore the development of functioning impairments and symptom occurrence during the last months of life of advanced cancer patients. Self-reported data from 116 patients who all completed the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30 (EORTC QLQ-C30) at 3, 2 and 1 month before death were analysed. All functioning as
The development and functional cycle of the mammary gland involves a number of processes that are caricatured by breast cancer cells during invasion and metastasis. Expression of the hypoxia-inducible transcription factors HIF-1 and HIF-2 has been associated with metastatic, poor prognosis, and high-grade breast cancers. Since hypoxia affects normal epithelial differentiation, we hypothesise that
Background: Impaired hand function is common in patients with arthritis and it affects performance of daily activities; thus, hand exercises are recommended. There is little information on the extent to which the disease affects activation of the flexor and extensor muscles during these hand-dexterity tasks. The purpose of this study was to compare muscle activation during such tasks in subjects w
