The efficacy and safety of nutrient supplements in the treatment of mental disorders: a meta‐review of meta‐analyses of randomized controlled trials
2019
The role of nutrition in mental health is becoming increasingly acknowledged. Along with dietary intake, nutrition can also be obtained from "nutrient supplements", such as polyunsaturated fatty acids (PUFAs), vitamins, minerals, antioxidants, amino acids and pre/probiotic supplements. Recently, a large number of meta-analyses have emerged examining nutrient supplements in the treatment of mental disorders. To produce a meta-review of this top-tier evidence, we identified, synthesized and appraised all meta-analyses of randomized controlled trials (RCTs) reporting on the efficacy and safety of nutrient supplements in common and severe mental disorders. Our systematic search identified 33 me…
Recovery of Historically Contaminated Watercourse Polluted by the Chemical Wood Industry: EROD Activity in Fish as Biomarker
2013
Despite outstanding process alterations over decades, pulp- and paper-mill-contaminated sediments and continuing exposure by the effluents may still have effects on biota. In this study, ecotoxicological impacts in the boreal watercourse were analyzed by measuring ethoxyresorufin-O-deethylase (EROD) induction from wild fish populations and from experimentally exposed fish. In order to assess the role of sediment-borne chemicals, juvenile rainbow trout (Oncorhynchus mykiss) were exposed in the laboratory to the surface sediments of Lake Vatianjarvi and Southern Lake Saimaa, both watercourses impacted by the chemical wood industry for approximately a century. Hepatic EROD activity was also me…
Glyphosate-based herbicide use affects individual microbial taxa in strawberry endosphere but not the microbial community composition
2023
AbstractAimsIn a field study, the effects of treatments of glyphosate-based herbicides (GBHs) in soil, alone and in combination with phosphate fertilizer, were examined on the performance and endophytic microbiota of garden strawberry.Methods and resultsThe root and leaf endophytic microbiota of garden strawberries grown in GBH-treated and untreated soil, with and without phosphate fertilizer, were analyzed. Next, bioinformatics analysis on the type of 5-enolpyruvylshikimate-3-phosphate synthase enzyme was conducted to assess the potential sensitivity of strawberry-associated bacteria and fungi to glyphosate, and to compare the results with field observations. GBH treatments altered the abu…
Heritable Epichloë symbiosis shapes fungal but not bacterial communities of plant leaves
2019
Keystone microbial species have driven eco-evolutionary processes since the origin of life. However, due to our inability to detect the majority of microbiota, members of diverse microbial communities of fungi, bacteria and viruses have largely been ignored as keystone species in past literature. Here we tested whether heritable Epichloë species of pooidae grasses modulate microbiota of their shared host plant. peerReviewed
Endofītiskās mikrobiotas pārstādīšana kā metodiska pieeja melnā plūškoka Sambucus nigra L. mikrobiotas funkcionālās lomas raksturošanai
2022
Darba mērķis bija noskaidrot, vai endofītiskās mikrobiotas pārstādīšana, kā metodiska pieeja, var sniegt informatīvus rezultātus S.nigra mikrobiotas funkcionālās lomas raksturošanai. Tika pārbaudīta hipotēze, ka mikrobiotas pārstādīšana ietekmē melnā plūškoka audu ķīmisko sastāvu. In vitro pētījumā noteikta mikrobiotas transplantācijas ietekme uz plūškoka šūnu suspensiju kultūrām, kallusiem un in vitro dzinumu kultūrām, izvērtējot augšanas parametrus un kopējo flavonoīdu un fenolu satura. In situ pētījumos analizēta kopējās mikrobiotas pārstādīšanas ietekme uz savvaļas S.nigra ogu un ziedu dabisko endofītisko mikrobiotu un fitoķīmisko sastāvu. Novēroja mikrobiotas ietekmi uz melnā plūškoka …
Insular endemism in the Mediterranean vascular flora: the case of the Aeolian Islands (Sicily, Italy)
2012
The present paper briefly provides the state of the art of the knowledge on vascular plant endemism in the oceanic (“thalassogenous”) Aeolian Archipelago (Sicily). Preliminary analysis of distribution areas and review of recent literature on biosystematics of endemic species revealed that: (a) Aeolian strictly endemic taxa are just 6, i.e. about the 0.7 % of the local vascular flora; among them, just 4 can be considered (with doubt) derived from in situ evolution. (b) The other 18 endemics are taxa occurring in wider areas, so they cannot be generally considered “locally evolved” but relicts. This preliminary analysis confirms that not only continental (“chersogenous”) but all Mediterranean…
Digital solutions transform the forest-based bioeconomy into a digital platform industry : a suggestion for a disruptive business model in the digita…
2018
With the notion that the transformation of the forest-based bioeconomy in recent years provides insightful suggestions not only on the bioeconomy, but on business innovation, this paper conducts an empirical analysis of the transformation and attempts to extract suggestions for a digital-solution-driven, disruptive business model in the digital economy. Notwithstanding the potential broad cross-sectoral benefits, the natural environment, locality constraints, and incessant challenge of distance have impeded the balanced development of the bioeconomy. However, driven by digital solutions, the bioeconomy has taken big steps forward in recent years. Digitalization has enabled real-time, end-to…
Digital Solutions in the Forest-Based Bioeconomy
2019
This chapter aims to illustrate the potential and significance of forest-based industry to take the lead in the sustainable development of the bio-based economy under digitalization. The digital solutions are transforming the forest-based industry by enabling the real-time end-to-end supply chain visibility, stock level optimization, demand planning, and real-time order status tracking and transparent, speedy, and hassle-free order fulfillment. In addition, increasing diversification corresponds to eco-consciousness, and shift in people’s preferences induces the transformation of forest-based bioeconomy into a digital platform industry. Further, this chapter will highlight the circular econ…
Biotic and abiotic soil properties influence survival of Listeria monocytogenes in soil
2013
International audience; Listeria monocytogenes is a food-borne pathogen responsible for the potentially fatal disease listeriosis and terrestrial ecosystems have been hypothesized to be its natural reservoir. Therefore, identifying the key edaphic factors that influence its survival in soil is critical. We measured the survival of L. monocytogenes in a set of 100 soil samples belonging to the French Soil Quality Monitoring Network. This soil collection is meant to be representative of the pedology and land use of the whole French territory. The population of L. monocytogenes in inoculated microcosms was enumerated by plate count after 7, 14 and 84 days of incubation. Analysis of survival pr…
The influence of backslopping on lactic acid bacteria diversity in tarhana fermentation
2020
Tarhana is produced at batch systems in which the microbiota has changed accordingly to the microbial load from ingredients. In order to stabilize the microbiota, the effects of backslopping carried out under different temperature regimes (25 and 30 °C), pH (3.70 and 4.00) and inoculation rates (5, 10 and 15%) on lactic acid bacteria (LAB) diversity were determined in tarhana dough. LAB and Total Aerobic Mesophilic Bacteria (TAMB) numbers increased in all tarhana dough samples subjected to backslopping. Temperature and pH significantly affected the microbiological diversity of tarhana whereas the different inoculation rates did not. Tarhana dough showed complex tarhana microbiota following …
