Article Synopsis
  • The aqueous extract of Ocimum selloi (alfavaca) is traditionally used for pain and inflammation, prompting research into its properties.
  • The study analyzed the chemical composition and anti-inflammatory effects of the leaves' aqueous extract (OSAE) and essential oil (OSEO) using various tests on mice models.
  • Results show that both OSAE and OSEO have significant anti-inflammatory and pain-relieving effects, with specific dosages effectively reducing inflammation and sensitivity, validating their popular medicinal use.

Social insects depend on their nests for protection against predation and abiotic threats. Accordingly, the chemical compounds present in the material wasps use to build their nests can both facilitate communication and repel predators. It is herein hypothesized that different wasp species build their nests with different structure and substrate materials and that such materials consist of chemical compounds related to unique wasp behavior and outside temperature variation.

Most flies of forensic importance are in two superfamilies, the Muscoidea and the Oestroidea, with similar life stages including the puparium. Upon completion of metamorphosis the adult fly emerges from the puparium, leaving behind an exuvia that is of potential significance in forensic investigation. The empty puparium is a durable piece of entomological evidence lasting several years.

The cuticle of social insects is a barrier against desiccation and a channel for chemical communication, two characteristics fundamental to the success of this group. The compounds present in the cuticle interact dynamically in order to achieve a balance between these two functions. Thus, viscosity correlates with waterproofing, whereas fluidity correlates with effective communication.
