RESUMEN
In recent years, short-form social media videos have emerged as an important source of health-related advice. In this study, we investigate whether experts or ordinary users in such videos are more effective in debunking the common misperception that talking about suicide should be avoided. We also explore a new trend on TikTok and other platforms, in which users attempt to back up their arguments by displaying scientific articles in the background of their videos. To test the effect of source type (expert vs. ordinary user) and scientific references (present or absent), we conducted a 2 × 2 between-subject plus control group experiment (n = 956). In each condition, participants were shown a TikTok video that was approximately 30 seconds long. Our findings show that in all four treatment groups, participants reduced their misperceptions on the topic. The expert was rated as being more authoritative on the topic compared to the ordinary user. However, the expert was also rated as being less credible compared to the ordinary user. The inclusion of a scientific reference did not make a difference. Thus, both experts and ordinary users may be similarly persuasive in a short-form video environment.
RESUMEN
RESUMEN El estudio de diferentes variables, como patogénesis, perfil inflamatorio, identificación de blancos terapéuticos, eficacia de tratamientos en modelos murinos ha resultado uno de los más prácticos para el estudio preclínico del cáncer de mama triple negativo (CMTN), el subtipo de cáncer más agresivo, con limitada aplicación de tratamientos y baja tasa de sobrevivencia. Sin embargo, hay que reconocer que existen otros menores en los que se viene estandarizando la inducción del CMTN. En esta revisión se engloban los diferentes métodos de inducción que han permitido el desarrollo de CMTN y las aplicaciones terapéuticas más relevantes por el que se desarrollaron los modelos murinos con CMTN.
ABSTRACT The study of different variables, such as pathogenesis, inflammatory profile, identification of therapeutic targets, efficacy of treatments in murine models has proven to be one of the most practical for the preclinical study of triple negative breast cancer (TNBC), the most aggressive subtype of cancer, with limited application of treatments and low survival rate. However, it must be recognized that there are other minors in which the induction of TNBC is being standardized. This review encompasses the different induction methods that have allowed the development of TNBC and the most relevant therapeutic applications by which murine models with TNBC were developed.
