The improvement of health and life conditions depends on various environmental factors. The exposition to organic and inorganic pollutants, as well as to the broad spectar of microorganisms is one of these factors. Medically important fungi have been increasing their number recently especially in urban and in recreational zones. Some of them, first of all molds and yeasts, are involved by different means in causing more or less serious diseases of man and animals. Frequency of alergic symptoms and human mycotic lesions increased significantly during last decades. Such phenomena have provoked more scientific attention recently. According to the available literature data, micro-fungi, causing mycoses and "environmental" fungi too could be considered as an important factor of health risk, being neglected and underestimated so far, especially in analyses of safe use of recreational waters and surrounding areas, among them swimming pools, river and sea beaches. On the basis of such statement there arises conclusion that water and ground of recreational zones could serve as vectors in transmission pathways of potentially or conditionally pathogenic fungi, being dangerous especially for immunocompromised individuals, which suggests inclusion of qualitative and quantitative composition of fungal community into a continual monitoring of hygienic status of recreational zones
Accurate neuroanatomical localization requires exact determination of boundaries of subcallosal area. Therefore, standardized criteria were proposed for definition of subcallosal area.
In the frame of biodiversity investigation of the Bardaca floodplain (Republic of Srpska, Bosnia), the investigation of the presence and the diversity of macrofungi of the wider Bardaca region have been undertaken. The relative poor generic diversity of lignicolous macrofungi with only 21 species (11 families) representing this group has been recorded. Such a poor qualitative and also quantitative composition of this very important fungal group could be explained by heavy devastation of autochthonous plant communities, reducing them to the small number of plant associations of poor generic composition. Consequently, drastic decrease of the diversity of ecological niches as fungal habitats was caused. Even though being preliminary, our results point to the necessity of conservation and protection of recent fungal diversity but, in our opinion, not by making so-called "Red list of endangered species", which, due to the lack of information and very poor evidence on this group of organisms in the region under the consideration, are extremely unreliable and therefore disputable but rather through the very short list of few not endangered species conditionally called "White list of not endangered fungal species", if such species recently exist at all.
We studied the influence of extremely low-frequency electromagnetic field (ELF EMF) to subcortical structures of a brain, i.e. basal ganglia, of sexually mature rats of Wistar strain. The animals were exposed to nonhomogenous ELF EMF, intensity of 50-500 μT, 50 Hz frequency, 7 hours a day, and 5 days a week during three months. Histological and stereological analysis established a reduction in volume density of ganglia cells in the area of basal ganglia, an increase of their nucleo-cytoplasmatic volume ratio, and presence of an intensive edema of pericellular (perineural) type
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
