Medial septum parvalbumin‐expressing inhibitory neurons are impaired in a mouse model of Dravet syndrome

open access: yesEpilepsia, EarlyView.
Abstract Objective Dravet syndrome (DS) is a severe neurodevelopmental disorder caused by pathogenic variants in the SCN1A gene, which encodes the voltage‐gated sodium channel Nav1.1 α subunit. Experiments in animal models of DS—including the haploinsufficient Scn1a+/− mouse—have identified impaired excitability of interneurons in the hippocampus and ...

The molecular mechanisms of defensive‐grade organic acid biosynthesis in ground beetles

open access: yesInsect Molecular Biology, EarlyView.
Formic acid and methacrylic acid are the primary defensive chemicals in the pygidial gland secretions of Platynus angustatus and Pterostichus moestus, respectively. Comparative transcriptomics suggests the folate cycle and valine catabolism may be involved in the biosynthesis of formic acid and methacrylic acid, respectively.

Sphingomyelinase D from loxosceles laeta venom induces the expression of MMP7 in human keratinocytes: contribution to dermonecrosis [PDF]

open access: yes, 2016
Envenomation by Loxosceles spider is characterized by the development of dermonecrosis. In previous studies, we have demonstrated that increased expression/secretion of matrix metalloproteinases 2 and 9, induced by Loxosceles intermedia venom Class 2 ...

Making with the Trouble: Un/Enfolding Posthuman Participants with Young People in Creative Post‐Qualitative Research

open access: yesInternational Journal of Art &Design Education, EarlyView.
Abstract This paper explores how ‘what matters’ can surface in multisensory arts‐informed projects as ways for young people to survive and stay with gender and sexuality troubles that are always more than theirs. Situated in an ex‐mining post‐industrial locale, we make an agential cut in a longitudinal research and engagement project called Unboxing ...

Transcriptome and venom proteome of the box jellyfish Chironex fleckeri [PDF]

open access: yes, 2015
Background: The box jellyfish, Chironex fleckeri, is the largest and most dangerous cubozoan jellyfish to humans. It produces potent and rapid-acting venom and its sting causes severe localized and systemic effects that are potentially life-threatening ...

Biologically active phenol and indole derivatives of terrestrial arthropods: electrophy­sio­logical and chemical characteristics

open access: yesБіологічні студії, 2019
Toxins-antagonists of glutamatergic synapses were found in venoms of different terrestrial Arthrpopodae, both Insecta and Aranei. Chemical structures of some of them were described, and a majority of such substances are derivatives of phenol and indole ...

Screening for Osteoporosis in Nonagenarians: A Scoping Review

open access: yesJournal of the American Geriatrics Society, EarlyView.
ABSTRACT Background As the United States population continues to age and advancements contribute to enhanced life expectancy, care for nonagenarians (adults aged 90 years and older) is as important as ever. A prominent concern within healthcare for the oldest old remains the occurrence of fragility fractures, and subsequent 1‐year mortality, making ...

Spider Knottin Pharmacology at Voltage-Gated Sodium Channels and Their Potential to Modulate Pain Pathways

open access: yesToxins, 2019
Voltage-gated sodium channels (NaVs) are a key determinant of neuronal signalling. Neurotoxins from diverse taxa that selectively activate or inhibit NaV channels have helped unravel the role of NaV channels in diseases, including chronic pain.
