We used two theoretical methods to estimate reduction potentials and acidity constants in Mn superoxide dismutase (MnSOD), namely combined quantum mechanical and molecular mechanics (QM/MM) thermodynamic cycle perturbation (QTCP) and the QM/MM-PBSA approach. In the latter, QM/MM energies are combined with continuum solvation energies calculated by solving the Poisson-Boltzmann equation (PB) or by

The study set out to explore whether an index of atrial electrical electrophysiology can be used to predict atrial fibrillation (AF) relapse, and if the predictive properties differ as a result of arrhythmia duration. METHODS AND RESULTS: The study comprised 175 consecutive patients with persistent AF (median duration 94 days, range 2 to 1044) referred for cardioversion. Twenty-nine patients had a

This multicenter study describes the development of a chemoradiation protocol for the treatment of non-metastatic squamous cell carcinoma of the esophagus. Eighty patients were treated with three courses of chemotherapy (cisplatinum and 5-fluorouracil) with concomitant radiotherapy (40 Gy) during the last two courses of chemotherapy. Esophagectomy was performed, when feasible. If no operation was

Background and aim of the study: The study aim was to analyze the relationship between patient-prosthesis mismatch (PPM) and in-hospital complications and mortality after aortic valve replacement (AVR). Methods: AVR was performed in 1,819 patients between January 1996 and July 2006. Follow up investigations were performed after a mean of 4.3 years (range: 0 days to 10.6 years). Univariate and mult

Background: Diabetes mellitus (DM) is an established risk factor for intermittent claudication (IC) and other manifestations of atherosclerotic peripheral arterial disease. Indications for surgery in infrainguinal IC are debated, and there are conflicting reports regarding its outcomes in patients with DM. Aims of this study were to compare both short- and long-term effects on total- and cardiovas

Drought in Australia has widespread impacts on agriculture and ecosystems. Satellite-based Fraction of Absorbed Photosynthetically Active Radiation (FAPAR) has great potential to monitor and assess drought impacts on vegetation greenness and health. Various FAPAR products based on satellite observations have been generated and made available to the public. However, differences remain among these d

Background--The relationship between "on-treatment" low platelet reactivity and longitudinal risks of major bleeding dual antiplatelet therapy following acute coronary syndromes remains uncertain, especially for patients who do not undergo percutaneous coronary intervention. Methods and Results--We analyzed 2428medicallymanaged acute coronary syndromes patients fromthe Targeted Platelet Inhibition

Despite the likely increasing co-occurrence of drought and heat stress, not least in equatorial regions, due to climate change, little is known about the combinational effect of these stresses on rice productivity and quality. This study evaluated the impact of simultaneous drought and temperature stress on growth, grain yield, and quality characteristics of seven rice cultivars from Rwanda, grown

Isoprene is a highly reactive volatile organic compound emitted by vegetation, known to be a precursor of secondary organic aerosols and to enhance tropospheric ozone formation under polluted conditions. Isoprene emissions respond strongly to changes in meteorological parameters such as temperature and solar radiation. In addition, the increasing CO2 concentration has a dual effect, as it causes b

Det terrestra ekosystemet absorberar cirka en tredjedel av de antropogena utsläppen varje år, vilket är en avgörande ekosystemtjänst som minskar ökningstakten av atmosfärisk koldioxid och bidrar till att mildra klimatförändringen. Observerade koncentrationer av atmosfäriskt koldioxid uppvisar en stor årlig variabilitet som främst anses vara orsakad av det terrestra ekosystemets respons på klimatföThe terrestrial ecosystem sequesters about one-third of anthropogenic emissions each year, thereby providing a critical ecosystem service that slows the rate of increase of atmospheric carbon dioxide and helps mitigate climate change. Observed atmospheric carbon dioxide concentrations exhibit a large inter-annual variability which is considered to be caused primarily by the response of the terrest

Living in a complex and dynamically changing environment requires accurate and timely behavioural responses that allow for adapting to such changes. Well-developed perceptual systems provide a continuous flow of abundant and up-to-date information on the changes in the environment, and, thereby, allow for tailoring behavioural responses accordingly. However, issuing any behavioral response would n

Aims and objectives: The aim of this study was to describe how EL was eased, as narrated by frail older people. Background: Existential loneliness (EL) is an unavoidable part of the human condition. It is a complex phenomenon that has been described as disconnection from life. If EL is acknowledged in the care of older people, the experience of EL can be reduced. Design: In this qualitative study,

Summary. Breast cancer in women under 30 years old carries a poor prognosis, for reasons that have not been identified. This study aimed to identify prognostic factors in this age group. Special attention was paid to the history of pregnancy. The clinical presentation and course of breast cancer was documented for 407 women, aged 20-29 years, who registered between 1978 and 1988 at one of nine can

This paper contains a quantification and decision theoretical optimization of the posterior utilities for several options for monitoring campaigns on the particular case of fatigue life predictions of an orthotropic steel deck. The monitoring campaigns are defined by varying monitoring durations and phases. The decision analysis is performed with real data from the Structural Health Monitoring (SH

Background: Employment is good for physical and mental health, however people with severe mental illness (SMI) are often excluded from employment. Standard Individual Placement and Support (IPS) is effective in supporting around 55% of people with SMI into employment or education. Current research considers enhancements to IPS to improve outcomes for those requiring more complex interventions. Cli

The growing need for human-machine interfaces (HMIs) underscores the importance of sensory feedback, with electrical stimulation offering efficient interaction in various applications. While its sensory effects are extensively studied, investigations into the reaction time (RT) following transcutaneous electrical stimulation (TES) remain limited. This study aimed to evaluate how stimulation parame

Background: Little is known regarding treatment with cangrelor during percutaneous coronary intervention (PCI) in patients with myocardial infarction complicated by cardiogenic shock or cardiac arrest. Objectives: The aim of this study was to investigate the effects of such cangrelor treatment during PCI in patients with myocardial infarction complicated by cardiogenic shock or cardiac arrest. Met

This thesis comprises three self-contained chapters that explore how individual behavior, incentives, and institutional frameworks shape the allocation of scarce resources, with particular emphasis on healthcare markets. The first chapter examines the impact of intrinsic truth-telling preferences on consumer welfare within a priority pricing mechanism, in which individuals can gain faster access t
