Understanding the Role of Silver Nanostructures and Graphene Oxide Applied as Surface Modification of TiO in Photocatalytic Transformations of Rhodamine B under UV and Vis Irradiation.

Materials (Basel) 2020 Oct 19;13(20). Epub 2020 Oct 19.

Department of Materials Technology and Chemistry, Faculty of Chemistry, University of Lodz, Pomorska 163, 90-236 Lodz, Poland.

This work is focused on photocatalytic properties of titanium dioxide thin coatings modified with silver nanostructures (AgNSs) and graphene oxide (GO) sheets which were analyzed in processes of chemical transformations of rhodamine B (RhB) under ultraviolet (UV) or visible light (Vis) irradiation, respectively. UV-Vis spectroscopy was applied to analyze the changes in the RhB spectrum during photocatalytic processes, revealing decolorization of RhB solution under UV irradiation while the same process coexisting with the transformation of RhB to rhodamine 110 was observed under Vis irradiation. The novelty of this study is the elaboration of a methodology for determining the parameters characterizing the processes occurring under the Vis irradiation, which enables the comparison of photocatalysts' activity.

The relationship between methods of scoring the alternate uses task and the neural correlates of divergent thinking: Evidence from voxel-based morphometry.

Neuroimage 2020 12 1;223:117325. Epub 2020 Sep 1.

Defence Research and Development Canada, Toronto Research Centre, 1133 Sheppard Avenue West, Toronto, ON M3K 2C9, Canada; University of Southern Denmark, Denmark.

Divergent thinking tests have been used extensively in neuroscientific studies of creativity. However, output from tests of divergent thinking can be scored in different ways, and those scores can influence assessments of divergent thinking performance and its relationship with brain activation. Here we sought to investigate the relationship between various methods of scoring the Alternate Uses Task (AUT)-a well-known test of divergent thinking-and regional grey matter volume (GMV) using voxel-based morphometry (VBM).

Dual cognitive pathways to voice quality: Frequent voicers improvise, infrequent voicers elaborate.

PLoS One 2019 27;14(2):e0212608. Epub 2019 Feb 27.

Department of Brain and Cognition, Faculty of Social and Behavioural Sciences, University of Amsterdam, Amsterdam, The Netherlands.

We investigate the involvement of Working Memory Capacity (WMC, the cognitive resource necessary for controlled elaborate thinking) in voice behavior (speaking up with suggestions, problems, and opinions to change the organization). While scholars assume voice requires elaborate thinking, some empirical evidence suggests voice might be more automatic. To explain this discrepancy, we distinguish between voice quantity (frequency of voice) and voice quality (novelty and value of voiced information) and propose that WMC is important for voice quality, but less for voice quantity.

Using stereoscopic visualizations as templates to construct a spatial hands-on representation-is there a novelty effect?

Adv Physiol Educ 2019 Mar;43(1):93-98

Institute of Biology and School Gardening, University of Education Karlsruhe , Karlsruhe , Germany.

Sculpting representations of human organs out of modeling clay is an acknowledged method of teaching anatomical structures. Because of its potential to provide detailed spatial information, stereoscopic imagery can be understood to function as a suitable template for such sculpting tasks. Currently, it is unknown whether the advantages of stereoscopic images for modeling structures result from enhanced depth impression alone, or whether task performance is impacted by factors such as situational intrinsic motivation and perceived competence while sculpting a human organ using stereoscopic imagery as template.

A Functional Model of Kitsch and Art: Linking Aesthetic Appreciation to the Dynamics of Social Motivation.

Front Psychol 2018 28;9:2437. Epub 2019 Jan 28.

Department of General Psychology and Methodology, University of Bamberg, Bamberg, Germany.

With the advent of modernity, change and novelty have become the core values of artistic production. At the same time the derogatory term "kitsch" was coined to contrast truly ground-breaking artistic achievements. In this article, we argue that kitsch and avant-garde art ideally represent two complementary types of aesthetic experience: a fluent one that allows for immediate emotional gratification (kitsch) and a disfluent one that requires cognitive elaboration (art).

Behavioral Plasticity and the Origins of Novelty: The Evolution of the Rattlesnake Rattle.

Am Nat 2016 Oct 28;188(4):475-83. Epub 2016 Jul 28.

Environmentally induced behavior (behavioral plasticity) has long been hypothesized to promote the origins of novel morphological traits, but this idea remains controversial. One context in which this hypothesis can be evaluated is animal communication, where behavior and morphology are often linked. Here, we examined the evolution of one of nature's most spectacular communication signals: the rattlesnake rattle. Read More

Genomic sources of phenotypic novelty in the evolution of eusociality in insects.

Authors:
Karen M Kapheim

Curr Opin Insect Sci 2016 02 12;13:24-32. Epub 2015 Nov 12.

Utah State University, Department of Biology, 5305 Old Main Hill, Logan UT 84322, USA. Electronic address:

Genomic resources are now available for closely related species that vary in social behavior, providing insight on the genomics of social evolution. Changes in the architecture of gene regulatory networks likely influence the evolutionary trajectory of social traits. Evolutionarily novel genes are likely important in the evolution of social diversity among insects, but it is unclear whether new genes played a driving role in the advent or elaboration of eusociality or if they were instead a result of other genomic features of eusociality.

The locus of sexual selection: moving sexual selection studies into the post-genomics era.

J Evol Biol 2015 Apr 17;28(4):739-55. Epub 2015 Apr 17.

Department of Biology, University of Maryland, College Park, MD, USA.

Sexual selection drives fundamental evolutionary processes such as trait elaboration and speciation. Despite this importance, there are surprisingly few examples of genes unequivocally responsible for variation in sexually selected phenotypes. This lack of information inhibits our ability to predict phenotypic change due to universal behaviours, such as fighting over mates and mate choice. Read More

Molecular basis for three-dimensional elaboration of the Aquilegia petal spur.

Proc Biol Sci 2015 Mar;282(1803):20142778

Department of Organismic and Evolutionary Biology, Harvard University, 16 Divinity Ave., Cambridge, MA 02138, USA

By enforcing specific pollinator interactions, Aquilegia petal nectar spurs maintain reproductive isolation between species. Spur development is the result of three-dimensional elaboration from a comparatively two-dimensional primordium. Initiated by localized, oriented cell divisions surrounding the incipient nectary, this process creates a pouch that is extended by anisotropic cell elongation. Read More

Diversity of cortical interneurons in primates: the role of the dorsal proliferative niche.

Cell Rep 2014 Dec 11;9(6):2139-51. Epub 2014 Dec 11.

Department of Neuroscience, University of Connecticut Health Center, Farmington, CT 06030, USA. Electronic address:

Evolutionary elaboration of tissues starts with changes in the genome and location of the stem cells. For example, GABAergic interneurons of the mammalian neocortex are generated in the ventral telencephalon and migrate tangentially to the neocortex, in contrast to the projection neurons originating in the ventricular/subventricular zone (VZ/SVZ) of the dorsal telencephalon. In human and nonhuman primates, evidence suggests that an additional subset of neocortical GABAergic interneurons is generated in the cortical VZ and a proliferative niche, the outer SVZ. Read More

Exploration of aziridine- and β-lactam-based hybrids as both bioactive substances and synthetic intermediates in medicinal chemistry.

Bioorg Med Chem 2013 Jul 23;21(13):3643-7. Epub 2013 Apr 23.

SynBioC Research Group, Department of Sustainable Organic Chemistry and Technology, Faculty of Bioscience Engineering, Ghent University, Coupure Links 653, B-9000 Ghent, Belgium.

The concept of pharmacophore hybridization is attracting an increasing interest from medicinal chemists. Whereas the main motivation for the application of this methodology relates to the pharmacological advantages associated with hybrid molecules, molecular hybridization can also deliver a synthetic advantage through selective chemical modification of the more reactive entity within hybrid systems. Moreover, if both features are combined, new hybrid structures result displaying both a biological and a synthetic benefit, and elaboration of this methodology might culminate in structural diversity and chemical novelty.

Incremental evolution of the neural crest, neural crest cells and neural crest-derived skeletal tissues.

J Anat 2013 Jan 14;222(1):19-31. Epub 2012 Mar 14.

Department of Biology, Dalhousie University, Halifax, NS, Canada.

Urochordates (ascidians) have recently supplanted cephalochordates (amphioxus) as the extant sister taxon of vertebrates. Given that urochordates possess migratory cells that have been classified as 'neural crest-like'- and that cephalochordates lack such cells--this phylogenetic hypothesis may have significant implications with respect to the origin of the neural crest and neural crest-derived skeletal tissues in vertebrates. We present an overview of the genes and gene regulatory network associated with specification of the neural crest in vertebrates. Read More

Ancestry of the mammalian preplate and its derivatives: evolutionary relicts or embryonic adaptations?

Rev Neurosci 2005 ;16(4):359-76

Departamento de Psiquiatría, Escuela de Medicina, Pontificia Universidad Católica de Chile.

Mammalian cortical development is preceded by the elaboration of a transient preplate, which is split into a superficial marginal zone and a deep subplate after the arrival of the cortical plate. There has been some controversy in the evolutionary interpretation of this transient structure, as some propose it to represent the ancestral cortex or pallium of non-mammals, while others consider it to be a phylogenetic novelty. The preplate and its derivatives contain components derived by both tangential and radial migration. Read More

From sensation to cognition.

Authors:
M M Mesulam

Brain 1998 Jun;121 ( Pt 6):1013-52

Department of Neurology, Northwestern University Medical School, Chicago 60611, USA.

Sensory information undergoes extensive associative elaboration and attentional modulation as it becomes incorporated into the texture of cognition. This process occurs along a core synaptic hierarchy which includes the primary sensory, upstream unimodal, downstream unimodal, heteromodal, paralimbic and limbic zones of the cerebral cortex. Connections from one zone to another are reciprocal and allow higher synaptic levels to exert a feedback (top-down) influence upon earlier levels of processing. Read More
