  Antitumor activity of scorpion venom-derived peptides: A meta-analysis of preclinical studies Abstract Despite advances in cancer therapeutics, there are still challenges in improving drug toxicity and selectivity. Peptides from various venous species have recently garnered attention for their biopharmaceutical potential, particularly in cancer. The present study aimed to conduct a meta-analysis of the antitumor activity of scorpion venom-derived peptides (SVDPs) previously reported in preclinical models. The bibliographic research included original and review articles written in English published from 2015 to 2026. Studies within the scope were retrieved from the EBSCO Discovery Service, PubMed, and WIPO databases. A total of 27 articles that met the inclusion and exclusion criteria were included in this research, and the collected data were synthesized through a meta-analysis. In the included in vitro and in vivo studies, the effect of SVDPs on breast/mammary gland, cervical,...

Three new species of orb-weaver spiders (Araneidae) from Humid Chaco in south-west Paraguay

Abstract 


Three new species of orb-weaver spider are described from Paraguay. Kaira mbywangiae sp. nov. has a remarkable complexity of abdominal humps and hump regions. Two species are described from the Humid Chaco flooded wetland region of Ñeembucú (Eustala davalosae sp. nov. and Kaira mbywangiae sp. nov.), and one from an Atlantic rainforest fragment in eastern Itapuá (Mangora sandovalae sp. nov.).
