Purification and characterisation of a plasmin-sensitive surface protein of Staphylococcus aureus.
Certain methicillin-resistant Staphylococcus aureus strains contain a 230-kDa cell-wall protein which is not present on the surface of other staphylococci. The presence of this 230-kDa protein is associated with a negative test result in commercial assays designed to detect fibrinogen-binding proteins and/or protein A on the staphylococcal surface. We have purified and partially characterised the 230-kDa protein from a lysostaphin digest of a non-agglutinating methicillin-resistant S. aureus strain. Partial amino acid sequence data obtained from the purified protein did not reveal any significant similarities to known proteins which indicates that the protein is novel. The 230-kDa protein w…

Planetary well-being
Tensions between the well-being of present humans, future humans, and nonhuman nature manifest in social protests and political and academic debates over the future of Earth. The increasing consumption of natural resources no longer increases, let alone equalizes, human well-being, but has led to the current ecological crisis and harms both human and nonhuman well-being. While the crisis has been acknowledged, the existing conceptual frameworks are in some respects ill-equipped to address the crisis in a way that would link the resolving of the crisis with the pivotal aim of promoting equal well-being. The shortcomings of the existing concepts in this respect relate to anthropocentric norma…
More Time Children Spend in Nature During Preschool Is Associated with a Greater Sense of Responsibility for Nature : A Study in Finland
Nature connectedness is an important factor underlying proenvironmental behavior. Only little is known on the aspects that influence nature connectedness in younger children. The study participants included 150 children at mean age of 6.5 years. Eighty-five of them attended nature-preschool that offers on average 13.1 h/week, and 65 of them typical preschool that offers on average 1.7 h/week, of their education in nature. Nature connectedness was measured with the connection to nature index. The regular visits to nature during preschool were associated with a higher sense of responsibility for nature (p = 0.013). The regular visits to nature during preschool, sex, parent's nature connectedn…
Nature exposure is not associated with parent-reported or objectively measured sleep quality in 6-year-old children : a study in Finland
Exposure to green environments has been associated with better sleep quality in adults. This study examined whether nature exposure is associated with parent-reported or actigraphy measured sleep quality in children. Against the hypotheses, no differences in sleep quality between the case and control groups or a moderating effect of socioeconomic status or sex were found. Green environment exposure may not serve as an environmental intervention to increase sleep quality in children. peerReviewed

Effects of vigorous late-night exercise on sleep quality and cardiac autonomic activity
Sleep is the most important period for recovery from daily load. Regular physical activity enhances overall sleep quality, but the effects of acute exercise on sleep are not well defined. In sleep hygiene recommendations, intensive exercising is not suggested within the last 3 h before bed time, but this recommendation has not been adequately tested experimentally. Therefore, the effects of vigorous late-night exercise on sleep were examined by measuring polysomnographic, actigraphic and subjective sleep quality, as well as cardiac autonomic activity. Eleven (seven men, four women) physically fit young adults (VO(2max) 54±8 mL·kg(-1)·min(-1) , age 26±3 years) were monitored in a sleep labor…
