MicroRNA Profiling and Bioinformatics Target Analysis in Dorsal Hippocampus of Chronically Stressed Rats: Relevance to Depression Pathophysiology
(FRONTIERS MEDIA SA, 2018)Studies conducted in rodents subjected to chronic stress and some observations in humans after psychosocial stress, have allowed to establish a link between stress and the susceptibility to many complex diseases, including ... -
Effect of yeast (Xanthophyllomyces dendrorhous) and plant (Saint John's wort, lemon balm, and rosemary) extract based functional diets on antioxidant and immune status of Atlantic salmon (Salmo salar) subjected to crowding stress
(ACADEMIC PRESS LTD- ELSEVIER SCIENCE LTD, 2018)Salmon farming may face stress due to the intensive culture conditions with negative impacts on overall performance. In this aspect, functional feed improves not only the basic nutritional requirements but also the health ... -
Transcriptional profiling of embryos lacking the lipoprotein receptor SR-B1 reveals a regulatory circuit governing a neurodevelopmental or metabolic decision during neural tube closure
(BMC, 2018)Background: The high-density lipoprotein receptor SR-B1 mediates cellular uptake of several lipid species, including cholesterol and vitamin E. During early mouse development, SR-B1 is located in the maternal-fetal interface, ... -
RIP-MD: a tool to study residue interaction networks in protein molecular dynamics
(PEERJ INC, 2018)Protein structure is not static; residues undergo conformational rearrangements and, in doing so, create, stabilize or break non-covalent interactions. Molecular dynamics (MD) is a technique used to simulate these movements ... -
SMZ/SNZ and gibberellin signaling are required for nitrate-elicited delay of flowering time in Arabidopsis thaliana
(OXFORD UNIV PRESS, 2018)The reproductive success of plants largely depends on the correct programming of developmental phase transitions, particularly the shift from vegetative to reproductive growth. The timing of this transition is finely ... -
Tuning the structure and magnetic behavior of Ni-Ir-based nanoparticles in ionic liquids
(ROYAL SOC CHEMISTRY, 2018)We report on a simple preparation of extremely small diameter (ca. 2 nm) Ni-Ir-based NPs using Ni(COD)(2) and [Ir(COD)OCH3](2) in 1-butyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (BMImNTf(2)). The prepared NPs ... -
Toward Controlled Morphology of FeCu Nanoparticles: Cu Concentration and Size Effects
(AMER CHEMICAL SOC, 2018)Bimetallic nanoparticles (NPs) can be tailored by varying the concentration of their constituent elements, resulting in novel structures and/or configurations, leading to interesting electronic, mechanical, and chemical ... -
Simple voltammetric analyses of ochratoxin A in food samples using highly-stable and anti-fouling black phosphorene nanosensor
(PERGAMON-ELSEVIER SCIENCE LTD, 2018)There are few reports on the electrochemical detection of ochratoxin A (OTA) using chemically modified electrode owing to the OTA poor electrochemical activity and strong fouling effect towards electrode surface. In this ... -
Growth of Ni nanoclusters on irradiated graphene: a molecular dynamics study
(ROYAL SOC CHEMISTRY, 2018)We studied the soft landing of Ni atoms on a previously damaged graphene sheet by means of molecular dynamics simulations. We found a monotonic decrease of the cluster frequency as a function of its size, but few big ... -
Bending energy of 2D materials: graphene, MoS2 and imogolite
(ROYAL SOC CHEMISTRY, 2018)The bending process of 2D materials, subject to an external force, is investigated, and applied to graphene, molybdenum disulphide (MoS2), and imogolite. For graphene we obtained 3.43 eV angstrom(2) per atom for the bending ... -
Small eukaryotic phytoplankton communities in tropical waters off Brazil are dominated by symbioses between Haptophyta and nitrogen-fixing cyanobacteria
(NATURE PUBLISHING GROUP, 2018)Symbioses between eukaryotic algae and nitrogen-fixing cyanobacteria have been recognized in recent years as a key source of new nitrogen in the oceans. We investigated the composition of the small photosynthetic eukaryote ... -
Metabolic potential and in situ transcriptomic profiles of previously uncharacterized key microbial groups involved in coupled carbon, nitrogen and sulfur cycling in anoxic marine zones
(WILEY, 2018)Anoxic marine zones (AMZs) impact biogeochemical cycles at the global scale, particularly the nitrogen cycle. Key microbial players from AMZs have been identified, but the majority remains unrecognized or uncharacterized. ... -
Ostreococcus tauri Luminescent Reporter Lines as Biosensors for Detecting Pollution From Copper-Mine Tailing Effluents in Coastal Environments
(FRONTIERS MEDIA SA, 2018)Phytoplankton cells are excellent biosensors for environmental monitoring and toxicity assessments in different natural systems. Green algae, in particular, appear to be more responsive to copper (Cu) disturbances. This ... -
Temperature modulates Fischerella thermalis ecotypes in Porcelana Hot Spring
(ELSEVIER GMBH, URBAN & FISCHER VERLAG, 2018)In the Porcelana Hot Spring (Northern Patagonia), true-branching cyanobacteria are the dominant primary producers in microbial mats, and they are mainly responsible for carbon and nitrogen fixation. However, little is known ... -
Understanding time use via data mining: A clustering-based framework
(IOS PRESS, 2018)In this work, a data mining framework is proposed to improve the understanding of how people allocate their time. Using a multivariate approach, we performed a clustering procedure, and subsequently a regression analysis ... -
Varieties of Capitalism and its Contributions to the Study of Development in Latin America
(CENTRO DE INVESTIGACION Y DOCENCIA ECONOMICAS, 2018)The literature on varieties of capitalism has significantly advanced the research on comparative political economy globally. In Latin America, this has been cited increasingly as a way to understand the development problems ... -
Distinctive Archaeal Composition of an Artisanal Crystallizer Pond and Functional Insights Into Salt-Saturated Hypersaline Environment Adaptation
(FRONTIERS MEDIA SA, 2018)Hypersaline environments represent some of the most challenging settings for life on Earth. Extremely halophilic microorganisms have been selected to colonize and thrive in these extreme environments by virtue of a broad ... -
High similarity in the microbiota of cold-water sponges of the Genus Mycale from two different geographical areas
(PEERJ INC, 2018)Sponges belonging to genus Mycale are common and widely distributed across the oceans and represent a significant component of benthic communities in term of their biomass, which in many species is largely composed by ... -
Species traits and network structure predict the success and impacts of pollinator invasions
(NATURE PUBLISHING GROUP, 2018)Species invasions constitute a major and poorly understood threat to plant-pollinator systems. General theory predicting which factors drive species invasion success and subsequent effects on native ecosystems is particularly ...
