GABAergic compensation in connexin36 knock-out mice evident during low-magnesium seizure-like event activity

Gap junctions within the cerebral cortex may facilitate cortical seizure formation by their ability to synchronize electrical activity. To investigate this, one option is to compare wild-type (WT) animals with those lacking the gene for connexin36 (Cx36 KO); the protein that forms neuronal gap junctions between cortical inhibitory cells. However, genetically modified knock-out animals may exhibit compensatory effects; with the risk that observed differences between WT and Cx36 KO animals could be erroneously attributed to Cx36 gap junction effects. In this study we investigated the effect of GABAA-receptor modulation (augmentation with 16 μM etomidate and blockade with 100 μM picrotoxin) on low-magnesium seizure-like events (SLEs) in mouse cortical slices. In WT slices, picrotoxin enhanced both the amplitude (49% increase, p = 0.0006) and frequency (37% increase, p = 0.005) of SLEs; etomidate also enhanced SLE amplitude (18% increase, p = 0.003) but reduced event frequency (25% decrease, p < 0.0001). In Cx36 KO slices, the frequency effects of etomidate and picrotoxin were preserved, but the amplitude responses were abolished. Pre-treatment with the gap junction blocker mefloquin in WT slices did not significantly alter the drug responses, indicating that the reduction in amplitude seen in the Cx36 KO mice was not primarily mediated by their lack of interneuronal gap junctions, but was rather due to pre-existing compensatory changes in these animals. Conclusions from studies comparing seizure characteristics between WT and Cx36 KO mice must be viewed with a degree of caution because of the possible confounding effect of compensatory neurophysiological changes in the genetically modified animals

Exemplary Design Research

In this paper, we will look at what role a research program and an interventionist research strategy based on design experiments may play for the advancement of knowledge relevant to design and designers. We suggest the notion of exemplary design research driven by programs and experiments and by this we refer to research based on the explicit formulation of design programs that act as a frame and foundation for carrying out series of design experiments. It is 'exemplary' in the sense that it enables critical dissemination primarily by creating examples of what could be done and how, i.e. examples that both express the possibilities and characteristics of the design program as well as more general suggestions about a certain (change to) design practice

Networks of Inventors in the Chemical Industry

By using extremely detailed data on European chemical patents, this work focuses on the micro levelof research networks. It examines the networks of inventors for the development of innovations. Itstudies whether the firm or the geographical proximity among inventors influences the probability thatinventors collaborate, and the attributes of the outcome patents. The results suggest that the firm, andin particular the large multinational company is a good coordination mechanism for fostering suchcollaborations. As for geographical proximity, it matters when the inventors are localised in atechnological cluster.industrial organization ;

Preparing Preservice Teacher for ALL Learners: A Book Critique on Gifted Education and Gifted Students

If is often said that undergraduate coursework in gifted education is a paragraph or chapter in a book. Without specific coursework regarding gifted education and gifted learners, preservice teachers are partially equipped to meet the diverse learning needs in today’s classrooms. This article provides a review of Gifted Education and Gifted Students: A Guide for Inservice and Preservice Teachers by Margot and Melin (2020) as a recommended primer for preservice teachers to gain basic knowledge and understanding of who gifted learners are and how to provided appropriate services for them
