We used allozymes to investigate the structure of genetic variation in populations of the perennial herb Silene nutans at local (Denmark), regional (Nordic area) and wide (over a 19A degrees latitudinal gradient) geographic scales in north-western Europe. New data from Denmark were combined with data from previously studied Fennoscandian and western populations. We related patterns of nuclear vari
BackgroundThere is a paucity of evidence for the use of systemic agents in children with atopic eczema refractory to conventional therapy, resulting in considerable variation in patient management. ObjectivesThe European TREatment of severe Atopic eczema in children Taskforce (TREAT) survey was established to collect data on current prescribing practice, to identify factors influencing the use of
Background: Stress ulcer prophylaxis (SUP) may decrease the incidence of gastrointestinal bleeding in patients in the intensive care unit (ICU), but the risk of infection may be increased. In this study, we aimed to describe SUP practices in adult ICUs. We hypothesised that patient selection for SUP varies both within and between countries. MethodsAdult ICUs were invited to participate in the surv
Background: Dead biomass, including woody debris (WD), is an important component of the carbon cycle in tropical forests. Aims: This study analyses WD (>2 cm) and other above-ground fluxes in mature tropical forest plots along an elevational gradient (210-3025 m above sea level) in southern Peru. Methods: This work was based on inventories of fine and coarse WD (FWD and CWD, respectively), above-g
Smoking is an established risk factor for pancreatic cancer, previously investigated by the means of questionnaires. Using cotinine as a biomarker for tobacco exposure allows more accurate quantitative analyses to be performed. This study on pancreatic cancer, nested within the European Prospective Investigation into Cancer and Nutrition (EPIC cohort), included 146 cases and 146 matched controls.
ABSTRACT Background: Frontotemporal dementia (FTD) constitutes a spectrum of neurodegenerative disorders associated with degeneration of, predominantly, the frontal and temporal lobes. The clinical heterogeneity is evident, and early diagnosis is a challenge. The primary objectives were to characterize psychotic symptoms, initial clinical diagnoses and family history in neuropathologically verifie
The radionuclide (210)Po is of importance from a radiation protection view and has properties that cause special problems when attempting to determine the body content in humans. Estimates have traditionally been made from either urine and/or fecal samples, which require a time-consuming radiochemical preparation before alpha spectrometric determination. In order to find a more simple and less lab
Patients with secondary acute myeloid leukemia (AML) often escape inclusion in clinical trials and thus, population-based studies are crucial for its accurate characterization. In this first large population-based study on secondary AML, we studied AML with an antecedent hematological disease (AHD-AML) or therapy-related AML (t-AML) in the population-based Swedish Acute Leukemia Registry. The stud
Aim of the study: Quality of cardiopulmonary resuscitation (CPR) is a critical determinant of outcome following out-of-hospital cardiac arrest. The aim of our study was to evaluate the quality of CPR provided by emergency medical service providers (Basic Life Support (BLS) capability) and emergency medical service providers assisted by paramedics, nurse anesthetists or physician-manned ambulances
BACKGROUND:: There is a lack of health-related quality of life (HRQOL) studies in Chinese women with cervical cancer. OBJECTIVE:: The objectives of this study were to investigate the HRQOL trajectory in women with cervical cancer in Mainland China in the 9 months following diagnosis and to identify factors that influence HRQOL. METHODS:: Initially, 187 patients with cervical cancer were included i
Neurodegenerative dementia, most frequently represented by Alzheimer's disease (AD) and dementia with Lewy bodies (DLB), is often accompanied by altered sleeping patterns and excessive daytime sleepiness. Studies showing an association between the neuropeptide orexin and AD/DLB-related processes such as amyloid-β (Aβ)1-42 plaque formation, α-synuclein accumulation, and inflammation indicate that o
Hyaluronic acid (HA) has been shown to affect angiogenesis and the function of the blood-brain barrier, and a crucial role for HA in atherosclerosis has been described. We have recently demonstrated changes in the levels of HA in cerebrospinal fluid (CSF) in patients with Alzheimer's disease (AD) with documented vascular alterations. To further investigate if the level of HA in CSF can be used as
Biomass gasification gas (BGG), a carbon-neutral renewable fuel and important hydrogen carrier, holds significant promise for sustainable energy systems. However, its practical implementation is challenged by combustion instability and elevated NOx emissions, primarily due to localized high-temperature zones induced by the hydrogen content. MILD (Moderate or Intense Low-oxygen Dilution) combustion
The aim of the present study was to find clinical parameters affecting incidence and progression of nephropathy in type 2 diabetic patients. A prospective study for 10 years was performed in 385 type 2 diabetic patients (diabetes diagnosis > or =30 years) attending a hospital-based outpatient clinic. Medical risk indicators like diabetes duration, HbA(1c), and blood pressure were related to the de
Background and aims: Several studies report a high prevalence of memory complaints in the elderly, non-demented population. Since the pathogenesis and diversity of memory impairment in healthy people is still an unresolved issue, we designed our study to ascertain the occurrence of brain abnormalities in Age-Associated Memory Impairment (AAMI) by measuring regional cerebral blood flow (rCBF). Meth
Previously, we have shown that short-term administration of adrenocorticotrophic hormone (ACTH) results in reduced concentrations of apolipoprotein B-containing lipoproteins, including lipoprotein(a), and reduced activities of hepatic lipase. These effects were observed in steroid-treated patients suffering from iatrogenic ACTH deficiency and in healthy individuals. The direct nature of the influe
