[Effectiveness of a repellent paint against the spider Loxosceles laeta].
BACKGROUND Loxoscelism is a severe reaction to the bite of the spider Loxosceles laeta. In recent years, a paint with repellent properties has been promoted in the commerce. However, there are no reports of experiments evaluating its effectiveness. AIM To evaluate experimentally the repellent properties of a paint against Loxosceles laeta. MATERIAL AND METHODS Males, females and nymphs of L...
متن کاملInfluence of spider silk on refugia preferences of the recluse spiders Loxosceles reclusa and Loxosceles laeta (Araneae: Sicariidae).
In a previous experimental study, recluse spiders Loxosceles reclusa Gertsch and Mulaik and Loxosceles laeta (Nicolet) (Araneae: Sicariidae) preferred small cardboard refugia covered with conspecific silk compared with never-occupied refugia. Herein, we investigated some factors that might be responsible for this preference using similar cardboard refugia. When the two Loxosceles species were g...
متن کاملRNA nanotechnology breakthrough for targeted release of RNA-based drugs using cell-based aptamers
Nucleic acids play different roles besides storing information and proteins coding. For example, single-stranded nucleic acids can fold into complicated structures with capability of molecular detection, catalyzing bioreactions and therapy. The development of RNA-based therapies has been rapidly progressed in the recent years. RNA aptamers are biomolecules with a size of 10 to 50 nm that can be...

متن کاملBrown Spider (Loxosceles genus) Venom Toxins: Tools for Biological Purposes
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. In general, spider venom is rich in biologically active molecules that are useful in experimental protocols for pharmacology, biochemistry, cell biology and immunology, as well as putative tools ...
