In this study, the concentration of GTX-III was quantified in the honey and Rhododendron flower samples collected from the Black Sea region. An Ultra High Performance Liquid Chromatography-Orbitrap®-High Resolution Mass Spectrometry (UHPLC-Orbitrap®-HRMS) analytical method was validated for the precise measurement of GTX-III isomers in both honey and flower matrices. The GTX-III concentrations ranged from 0 to 6.59 mg/g in honey and 33.57–44.99 mg/g in flowers. Additionally, the concentration of GTX-III in honey was found to correlate with the density of Rhododendron pollen present in the honey. The study confirmed that the UHPLC-Orbitrap®-HRMS method is a reliable and sensitive tool for the accurate quantification of GTX-III.

When studying venom ontogeny, juveniles and adults are often determined by size at sexual maturity. However, in gape-limited predators such as snakes, venom shifts may occur earlier, coinciding with an increase in jaw size that allows the intake of larger prey. This study explored venom variation in <em>Vipera ammodytes</em> along the snout-vent length (SVL), linking these changes to dietary shifts and reproductive status. A total of 57 venom samples from two populations were analysed using chip electrophoresis (CE) and MALDI-TOF mass spectrometry. Individuals were categorised into three groups: immature individuals feeding on lizards (<300 mm SVL), immature individuals feeding on lizards but start including mammals in their diet (between 300 and 440 mm), and mature individuals feeding on mammals and lizards (>440 mm). Significant venom composition changes around 300 mm SVL were observed, aligning with a dietary shift marked by increased mammalian prey intake and preceding sexual maturity. This finding highlights the need to use SVL as a metric for accurate venom analysis along ontogeny. Our results indicate that when pooling venom samples is necessary, allocating individuals to age categories should be based on dietary shifts rather than sexual maturity. Additionally, CE and MALDI-TOF MS proved effective in detecting ontogenetic venom changes, offering a fast and affordable approach to venom profiling.

Since the early times of antivenoms, the neutralization of venom's lethality has been predominantly based on the incubation of venom and antivenom prior to the injection in laboratory animals. The present narrative review summarizes the main milestones in the development of venom neutralization assays by antivenoms, starting with the pioneer work of Albert Calmette and Vital Brazil. Despite various initiatives along the 20th century to standardize these tests, the antivenom efficacy assays have been highly heterogeneous between laboratories and countries. Efforts carried out to understand the main variables that determine the lethality neutralization tests are discussed, together with the introduction of assays to assess the neutralization of other relevant toxic and enzymatic activities of venoms, which complement the lethality assay. In the last decades, international efforts coordinated by the World Health Organization (WHO) led to the publication of the WHO guidelines for the production and control of antivenoms, which comprise detailed descriptions of preclinical neutralization assays, including the essential test, i.e., lethality, and supplementary assays that assess other relevant toxic effects.
