Recent Advances in Research on Widow Spider Venoms and Toxins
Toxins, 2015 Widow spiders have received much attention due to the frequently reported human and animal injures caused by them. Elucidation of the molecular composition and action mechanism of the venoms and toxins has vast implications in the treatment of ...

Brown Spider (Loxosceles genus) Venom Toxins: Tools for Biological Purposes
Toxins, 2011 Venomous animals use their venoms as tools for defense or predation. These venoms are complex mixtures, mainly enriched of proteic toxins or peptides with several, and different, biological activities.

Journal of Venomous Animals and Toxins including Tropical Diseases, 2018 Background Loxoscelism is a severe human envenomation caused by Loxosceles spider venom. To the best of our knowledge, no study has evaluated the presence of antibodies against Loxosceles venom in loxoscelism patients without treatment with antivenom ...

Tying pest insects in knots: the deployment of spider-venom-derived knottins as bioinsecticides.
Pest Management Science, 2019 Spider venoms are complex chemical arsenals that contain a rich variety of insecticidal toxins. However, the major toxin class in many spider venoms is disulfide-rich peptides known as knottins.

Toward a unified understanding of people’s aversion to nature: biophobia
Frontiers in Ecology and the Environment, EarlyView.Human–nature relationships are often framed positively, but research rarely addresses biophobia, the aversion to nature. However, negative relationships with nature are likely to become more widespread following societal and environmental changes, with serious implications for public health and conservation efforts.
