Translating Knowledge of Sexual Configurations Theory via Instructional Videos.

Gender/sex and sexual diversity are increasingly understood by the public as complex. But, scientific frameworks that address the complexity of gender/sex and sexual diversity are few and not well situated for the public. Sexual configurations theory (SCT; van Anders, 2015) is one approach that provides a visual framework for understanding and measuring gender/sex and sexual diversity. But how might knowledge users and creators actually use it? To make SCT more accessible to researchers, educators, clinicians, and the general public, we created three instructional videos (individual gender/sex, gender/sex sexuality, and partner number sexuality) that explained SCT and demonstrated how to use its diagrams. Participants (N = 242) of diverse gender/sex and sexual identities, including professionals who work in gender/sex- and sexuality-related fields, watched one of the three videos, filled out the diagrams, and evaluated the video and diagrams via scaled and open-ended questions. Results demonstrated that the SCT videos were sufficient for most participants to fill out the diagrams. Participants evaluated the video generally positively, with some variation by condition, identity group, and professional status. These results indicate that instructional videos are able to translate SCT, potentially facilitating uptake of SCT by clinicians, researchers, and educators as well as increasing awareness of gender/sex and sexual diversity more broadly within the public.

Stachybotrychromenes A-C: novel cytotoxic meroterpenoids from Stachybotrys sp.

In the course of gaining new insights into the secondary metabolite profile of various Stachybotrys strains, in particular concerning triprenyl phenol-like compounds, so far, unknown metabolites with analogous structural features were discovered. Three novel meroterpenoids containing a chromene ring moiety, namely stachybotrychromenes A-C, were isolated from solid culture of the filamentous fungus Stachybotrys chartarum DSMZ 12880 (chemotype S). Their structures were elucidated by means of comprehensive spectroscopic analysis (1D and 2D NMR, ESI-HRMS, and CD) as well as by comparison with spectroscopic data of structural analogues described in literature. Stachybotrychromenes A and B exhibited moderate cytotoxic effects on HepG2 cells after 24 h with corresponding IC50 values of 73.7 and 28.2 µM, respectively. Stachybotrychromene C showed no significant cytotoxic activity up to 100 µM. Moreover, it is noteworthy that stachybotrychromenes A-C are produced not only by S. chartarum chemotype S but also S. chartarum chemotype A and Stachybotrys chlorohalonata.
