The Comparison of Cellulolytic Activity of the Modified Soil Treated with Roundup
2016
Abstract The activity of soil microorganisms affects soil fertility and structure, what leads to satisfactory crop yields, thanks to changes in the decay of organic matter. Their activity may be impaired as a result of application by farmers both fertilizers and pesticides. The degradation of cellulosic biomass represents an important part of the carbon cycle within the biosphere. Cellulolitic microorganisms are responsible for this decomposition, as they produced the enzymes of the cellulase complex. The aim of the study was to compare the cellulolytic activity of soil with Roundup and modified using urea phosphate and / or manure. The pot experiment was conducted under laboratory conditio…
Pathogenic Escherichia coli Among Asymptomatic Children and Associated Factors
2020
Abstract Although Escherichia coli is a part of the commensal flora of the gastrointestinal tract, pathogenic types of E. coli can cause diarrhea, especially in children. Pathogenic types are found also in healthy individuals, but prevalence of pathogenic E. coli among asymptomatic children varies and has not been studied in Latvia. The aim of the study was to determine prevalence of pathogenic E. coli among asymptomatic children and identify factors associated with presence of bacterium. Children (aged 0.5–8 years) without acute gastrointestinal symptoms were included in a cross-sectional study. Parents were asked to answer a questionnaire (demographic data, parental education, type of del…
Proteome Analysis of Colorectal Cancer Cell Line SW480 Released Extracellular Vesicles
2018
The detection and profiling of disease-specific extracellular vesicles (EVs) from body fluids has been challenging research area during recent years. However, the question – can EVs surface proteins be exploited as a credible tool for early cancer diagnosis – is still not answered. Objective of the current study was to find out whether hypoxia induces differences in protein profiles of EVs released from hypoxic human colorectal cancer cells SW480 (EVHyp) and EVs released from these cells grown in normoxic conditions – EVNorm. Obtained results show differences in EVs surface protein samples. Some protein fragments were found only or mostly in EVHyp surface protein samples. Finding of one or …
La couverture vaccinale contre la grippe saisonnière du personnel soignant en gériatrie : mise au point
2016
Resume Position du probleme La vaccination antigrippale des professionnels de sante semble representer l’une des actions preventives des plus efficaces face a une pathologie a haut risque d’epidemie nosocomiale et potentiellement grave en milieu geriatrique. Ce travail avait pour objectif de faire une mise au point sur le statut vaccinal antigrippal chez le personnel soignant en geriatrie et les raisons expliquant leur reticence vis-a-vis de cette vaccination, afin d’emettre des propositions d’amelioration de la couverture vaccinale. Methode Une recherche bibliographique des articles publies depuis 2000 dans le domaine de la geriatrie, des maladies infectieuses ou de la pneumologie a ete re…

Biodeterioration represents a revealing problem for the conservation of cultural heritage. It can be identified as a complex interaction within the ecosystem of a microbial community and its substrate and involves physical and chemical alterations resulting from biological and metabolic activity. Designing a diagnostic approach for evaluating the extent of the damage, identifying the biological community, and opting for an efficient methodology aimed at eliminating deteriogens is equally complicated. The correct approach would require understanding the nature of the biodeterioration and implementing methodologies respectful of human health which, however, avoid the indiscriminate killing of…
Biodeterioration
2017
The biodeterioration of organic and inorganic materials, as well as polymers, is a complex of alteration processes induced by the growing and metabolic activ- ity of organisms. It can be recognized on monuments, wall paintings, stone, wood, paper, vegetal/animal fibers, and parchment artworks. As defined by Hueck (1968), biodeterioration is “any undesirable change in the properties of a material caused by the vital activities of organisms”; this definition is accepted as the meaning of the phenomenon. Both macroorganisms (such as animals, plants and mosses) and microorganisms (such as autotrophic or het- erotrophic bacteria, microfungi, cyanobacteria, algae and lichens) represent the trigge…
