RESUMO
Three bipyridinium phenolates were synthesized, and their spectral behavior was recorded at various solvent polarities and compared to a classic pyridinium phenolate dye possessing only one pyridinium acceptor ring in its structure. The addition of a second pyridinium unit to the classic solvatochromic core results in an unexpected change in the spectral behavior from negative solvatochromism (displacement of the absorption band to shorter wavelengths) to inverted solvatochromism, characterized by the transition from negative to positive solvatochromism (displacement of the absorption band to longer wavelengths) at moderate solvent polarities.
RESUMO
Con el incremento en las tasas de infertilidad en los últimos años a un 15% a nivel mundial, ha habido un aumento en las consultas de medicina reproductiva para tratamientos de alta y baja complejidad. Estos tratamientos requieren un proceso largo y complejo, desde su diagnóstico hasta el fin del tratamiento. El objetivo de esta revisión bibliográfica es conocer la importancia que tiene el rol de matronas/matrones en las unidades de medicina reproductiva, fundamentalmente en el acompañamiento y educación de los pacientes.
With infertility rates increasing in recent years to 15% worldwide, there has been an increase in reproductive medicine consultations for high and low complexity treatments. These treatments require a long and complex process, from its diagnosis to the end of the treatment. The aim of this bibliographic review is to understand the importance of the role of the midwife in reproductive medicine units, fundamentally in the accompaniment and education of patients.
