Article Synopsis
- Effective research in natural sciences requires that findings be comparable and reproducible, especially in the context of understanding biodiversity and ecological patterns.
- A study analyzed 470 papers on Brazilian ant diversity from the past 50 years, revealing that while 73.6% specified identification methods, only 5.8% provided complete data on specimen repositories.
- The research indicates a growing acknowledgment of the importance of taxonomy in biodiversity studies, with more specialists and institutions involved and an increase in transparency about taxonomic procedures.
Article Synopsis
- Neglected tropical diseases (NTDs) are currently treated with therapies that have limited effectiveness and can be toxic.
- A study has found that venom from the Dinoponera quadriceps ant (DqV) shows antimicrobial properties against the parasites Leishmania amazonensis and Trypanosoma cruzi, inhibiting their growth while having low toxicity to human host cells.
- The mechanism of action involves causing cell death in T. cruzi through necrotic and apoptotic pathways, as indicated by various microscopy and staining techniques used to observe changes in the parasites' cellular structures.
Dinoponera quadriceps (Hymenoptera, Formicidae, Ponerinae) is a primitive and endemic ant of Northeastern Brazil, that uses its sting and associated venom gland to capture preys and for defense. Venom of Dinoponera is of potential clinical importance, since it causes intense local pain, accompanied by erythema and edema, when injected by the sting. With other hymenopteran venoms, inflammatory effects are also reported.

Anticoagulant activity is another biological property that has been shown for the venom of other hymenopteran species, like wasps. The aim of this study was to assess the anti-inflammatory, anticoagulant and antiplatelet properties of D.

Human accidents occasionally occur and cause local pain and systemic symptoms. A comprehensive study of the D.

The aim of this study was to evaluate the effects of Dinoponera quadriceps venom (DqV) on seizure models in mice induced by pentylenetetrazole (PTZ), pilocarpine, and strychnine. In the PTZ model, intraperitoneal treatment with DqV (0.
