  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,...

Abstract

The new synanthropic crevice weaver spider species, from the family Filistatidae, Pikelinia floydmuraria sp. nov. (male and females) is described from the department of Tolima, Colombia. The female internal genitalia of P. fasciata from the Galapagos islands, Ecuador, is described here for the first time. Additional unidentified species of Pikelinia populations were recorded in the departments of Cauca, Quindío, and Risaralda. Dietary analysis of P. floydmuraria sp. nov. (Tolima) and Pikelinia sp. (Armenia) revealed a predominance of Hymenoptera (~35% of prey), followed by Diptera and Coleoptera. This study expands known diversity and trophic ecology of Pikelinia genus.
