  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,...

Descriptions of undescribed sexes of Theraphosidae spiders (Mygalomorphae: Plseiopelma, Tmesiphantes) from northern Argentina

Abstract

Females previously unknown from two Argentinean tarantula (Theraphosidae), Plesiopelma paganoi Ferretti & Barneche, 2014 and Tmesiphantes crassifemur (Gerschman & Schiapelli, 1960) are described for the first time. Both specimens were collected at the type locality or very close to it to assure to be conspecific. The female of P. paganoi can be distinguished from congeners by the high number of labial and maxillary cuspules and the shape of the spermathecae with very short and non-spiraled ducts. The female of T. crassifemur is characterized by the shape of the spermathecae and the absence of spiniform setae on coxa III and IV. New diagnosis are presented and a distribution map of both species.
