Specimens of large fungi (mushrooms) were screened for mutagenic activity by the Salmonella/microsome assay, with strains TA98, TA2637 and TA100. Out of 48 species tested, 37 exhibited a significant but for the most part weak activity. The activity observed in the presence of S9 mix was typically between 0 and 50% of that without, and in no case was the activity increased in the presence of micros
Invasive plants cause substantial economic and environmental damage throughout the world. However, eradication of most invasive species is impossible and, in some cases, undesirable. An alternative is to slow the spread of an invasive species, which can delay impacts or reduce their extent. We identify three main areas where models are used extensively in the study of plant spread and its manageme
Background: Due to a lack of coordination of care flow events and uncertain capacity coordination, long patient waiting times for patients arise, entailing a medical risk and contributing towards capacity being utilized less effectively. Healthcare services are often said to be crucial to coordinate in order to create equally good availability for care-seekers. Could healthcare matching become the
PURPOSE: About 60% of ovarian cancers are diagnosed at late stage, when 5-year survival is less than 30% in contrast to 90% for local disease. This has prompted search for early detection biomarkers. For initial testing, specimens taken months or years before ovarian cancer diagnosis are the best source of information to evaluate early detection biomarkers. Here we evaluate the most promising ovar
Objectives: Audiologists provide professional contact and support between appointments to clients with hearing impairment using telephone and e-mail, but more advanced and flexible technological platforms are also possible. The present study aimed to evaluate the clinical application of an Internet-based support system for audiologists and their first-time hearing aid clients. Design: An Internet-
The aim of this study was to validate the Edholm scale (Edholm, 1966) and the ISO 8996 standard (International Organization for Standardization [ISO], 1990) by comparing the metabolic rates estimated for both methods with the actual measured metabolic rate (MMeas) in 6 manual material handling tasks simulated under laboratory conditions. The metabolic rate was calculated from oxygen consumption VO
Objective – The role of the academic librarian has become increasingly educative in nature. In this study, the critical friend method was introduced among teaching librarians in an academic setting of medicine and health sciences to ascertain whether this approach could be implemented for feedback on teaching of these librarians as part of their professional development. Methods – We used a singl
The article presents an analysis of boundary work within the context of care for the elderly, where violence appears to be widespread though still relatively unacknowledged. By resorting to certain descriptive – often jocular – modes, the staff designate aggressive acts committed by patients as 'non-violent'. This occurs although intent, responsibility, and injury – all common criteria associated
To assess the role of CHCHD2 variants in patients with Parkinson disease (PD) and Lewy body disease (LBD) in Caucasian populations.
Popular Abstract in Swedish Tillväxtfaktorer påverkar signaler mellan celler i hjärnan Människors hjärnor innehåller flera miljarder hjärnceller, vilka är förutsättningen för vårt beteende, våra känslor och våra tankar. Hjärncellerna bildar kontakter, synapser, med varandra. Genom dessa överförs signaler från en cell till en annan. Varje cell kontaktar en mängd andra celler, både sådana med liknanThe neurotrophins, notably brain-derived neurotrophic factor (BDNF) and neurotrophin 3 (NT3), modulate synaptic transmission and synaptic plasticity in the adult mammalian brain. Recent data suggest that neurotrophins might be mediators of activity-dependent synaptic plasticity. Such plasticity is believed to be a cellular correlate for important processes like learning, but also for diseases, for
The impact of BRICS (Brazil, Russia, India, China, and South Africa) and other emerging economies on the field of international development has seen traditional donor nations wrestle with fundamental shifts in the geometry and makeup of the donor community. This has resulted in asymmetrical power relations in organizations such as the Organisation for Economic Co-operation and Development (OECD) f
