Toxins, 2017 Spider venoms are rich cocktails of bioactive peptides, proteins, and enzymes that are being intensively investigated over the years. In order to provide a better comprehension of that richness, we propose a three-level family classification system for ...

Ballooning Spiders: The Case for Electrostatic Flight [PDF]
arXiv, 2013 We consider general aspects of the physics underlying the flight of Gossamer spiders, also known as ballooning spiders. We show that existing observations and the physics of spider silk in the presence of the Earth's static atmospheric electric field indicate a potentially important role for electrostatic forces in the flight of Gossamer spiders.

Contact Urticaria and Related Conditions: Clinical Review
Contact Dermatitis, EarlyView.ABSTRACT Contact urticaria (CoU) is an immediate contact reaction occurring within minutes to an hour after exposure to specific proteins or chemicals. CoU is categorised into non‐immunologic (NI‐CoU) and immunologic (I‐CoU) types, with I‐CoU potentially leading to anaphylaxis. Both forms of CoU can be associated with protein contact dermatitis and the

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

International 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 ...

Біологічні 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 ...

Testing Mean Stability of Heteroskedastic Time Series
Journal of Time Series Analysis, EarlyView.ABSTRACT Time series models are often fitted to the data without preliminary checks for stability of the mean and variance, conditions that may not hold in much economic and financial data, particularly over long periods. Ignoring such shifts may result in fitting models with spurious dynamics that lead to unsupported and controversial conclusions ...

Spider Venom as Bio-Insecticide
, 2023 Insecticidal toxins derived from insect predators and parasitoids are of growing interest in the development of bio-insecticides at present. One of the major features contributing to the overall success of spiders is the production of a highly toxic venom from their venom glands that they employ to subdue prey and deter predators.

Applications of venom biodiversity in agriculture
EFB Bioeconomy Journal, 2021 Agriculture can benefit from the biotechnological use of animal venom biodiversity. We explored the patent database to find the prevailing applications of scorpion, snake, spider, bee, and wasp venoms for agricultural purposes.
