Vitiligo is a chronic disease of unknown etiology that causes progressive cutaneous depigmentation. Current pharmacological treatments have limited success and present significant risks. Many efforts have been made in recent years to explore new anti-vitiligo therapeutic strategies, including herbal-based therapies. The objective of the present review is to provide an updated overview on the most frequently used medicinal plants in the treatment of vitiligo. A bibliographical search was carried out in scientific databases Pubmed, Scifinder, Scopus, Google Scholar, and Medline up to October 2021 using the descriptors vitiligo, herbal, medicinal plants, and alternative therapies. In our search, the highest number of published studies comprise plants commonly used in traditional herbal medicine, highlighting the usefulness of ethnopharmacology in the discovery of new therapeutic agents. The review outlines current understanding and provides an insight into the role of psoralens and khellin (photosensitizing agents obtained from plants such as Cullen corylifolium or Ammi visnaga). The paper also describes other traditional herbs such as Ginkgo biloba, Phlebodium aureum, Piper nigrum, Picrorhiza kurroa, and Baccharoides anthelmintica that can likewise act as potential therapeutical agents. Based on our findings, photosensitizing agents in combination with phototherapy, the association of oral Phebodium aureum with phototherapies as well as oral G. biloba in monotherapy showed greater scientific evidence as therapeutic options. The research results emphasize that further investigation in this area is merited. More long-term follow up clinical trials and higher quality randomized trials are needed.

The incidence and prevalence of age-related neurodegenerative dementias have been increasing. There is no curative therapy and conventional drug treatment can cause problems for patients. Medicinal plants traditionally used for problems associated with ageing are emerging as a therapeutic resource. The main aim is to give a proposal for use and future research based on scientific knowledge and tradition. A literature search was conducted in several searchable databases. The keywords used were related to neurodegenerative dementias, ageing and medicinal plants. Boolean operators and filters were used to focus the search. As a result, there is current clinical and preclinical scientific information on 49 species used in traditional medicine for ageing-related problems, including neurodegenerative dementias. There are preclinical and clinical scientific evidences on their properties against protein aggregates in the central nervous system and their effects on neuroinflammation, apoptosis dysregulation, mitochondrial dysfunction, gabaergic, glutamatergic and dopaminergic systems alterations, monoamine oxidase alterations, serotonin depletion and oestrogenic protection. In conclusion, the potential therapeutic effect of the different medicinal plants depends on the type of neurodegenerative dementia and its stage of development, but more clinical and preclinical research is needed to find better, safer and more effective treatments.

La obligada adaptación del proceso enseñanza/aprendizaje a entornos no presenciales, debido a la expansión del virus SARSCOV- 2, ha motivado el diseño y ejecución de herramientas de aprendizaje basadas en TICs, que integren, además de los contenidos indispensables para la adquisición de competencias profesionales, un entorno atractivo para el aprendizaje autónomo de los alumnos. Mediante un paquete informático de implementación rápida (click & collect) en plataformas virtuales de diferentes universidades, adaptado al nivel medio de conocimientos informáticos del profesorado en Ciencias de la Salud, se han diseñado unas clases prácticas de la asignatura Farmacognosia y Fitoterapia correspondiente a los Grados de Farmacia y Farmacia y Nutricion Humana y Dietética de la UCM y las Universidades CEU San Pablo y CEU Cardenal Herrera. Se han incluido presentaciones ppsx interactivas y micro-vídeos de prácticas reales, incluyendo aciertos y fallos más comunes. En una primera evaluación de su eficacia se han observado resultados muy positivos tanto en el grado de aceptación por los alumnos como por el profesorado. La herramienta diseñada no sólo permitirá una adaptación rápida de la docencia presencial a online, sino que podrá ser empleada para favorecer el aprendizaje presencial y para la formación de postgrado.

The retina may suffer neurodegenerative damages, as other tissues of the central nervous system do, and serious eye diseases may develop. One of them is age-related macular degeneration, which causes progressive loss of vision due to retina degeneration. Treatment of age-related macular degeneration focuses on antioxidant agents and anti-vascular endothelial growth factor compounds, among others, that prevent/ diminish oxidative stress and reduce neovascularisation respectively. The phytochemicals, medicinal plants and/or plant-diet supplements might be a useful adjunct in prevention or treatment of age-related macular degeneration owing to their antioxidant and anti-vascular endothelial growth factor properties. This review article presents the most investigated plants and natural products in relation to age-related macular degeneration, such as saffron, ginkgo, bilberry and blueberry, curcuma or turmeric, carotenoids, polyphenols, and vitamins C and E. This study provides up-to-date information on the effects, treatments, safety and efficiency of these phytotherapy products.

La clase invertida es un modelo pedagógico creado en 2012 por Jonathan Bergmann y Aaron Sams, profesores de Química en Woodland Park High School (Woodland Park Colorado). En este modelo, el profesor, en lugar de utilizar el tiempo de la clase para introducir nueva materia (vía lección magistral), previamente a que tenga lugar la clase proporciona a los alumnos, a través de la plataforma virtual, material docente (videos, artículos, podcast, etc.) para ayudarles a clarificar la materia objeto de estudio, de manera que puede utilizar el tiempo de la clase para realizar actividades docentes colaborativas. El material docente debe incluir las ideas principales de la unidad de estudio y puede ser creado por el profesor o descargado de internet. Esta actividad se ha desarrollado en el primer cuatrimestre del curso 2018-19 en las asignaturas Farmacología Clínica en el Grado de Farmacia y Farmacología del Grado en Medicina. Basándonos en los resultados obtenidos, la actividad ha resultado muy interesante para los estudiantes. La clase invertida les ha ayudado a clarificar conceptos y algunos estudiantes han considerado que tener conocimientos previos es importante para realizar la actividad, aunque no es esencial. / Flipped classroom is a pedagogical model created in 2012 by Jonathan Bergmann and Aaron Sams, Chemistry teachers at Woodland Park High School (Woodland Park Colorado). In this model, rather than taking up limited class time to explain a new concept (often via lecture), the teacher add a variety of learning material (videos, articles, podcast. etc.) to Blackboard before class. The objective is to introduce students to the concepts that they are going to study during class, freeing up class time for more collaborative activities. Learning material includes main concepts and ideas of the unit of study and it can be produced originally by the teacher or it can be acquired from internet. The activity has been carried out during the first semester of the academic year 2018-19 in the subjects Clinical Pharmacology and Pharmacology in Pharmacy and Medicine degrees, respectively. Acquired knowledge of students was evaluated by Kahoot tests and a survey was conducted to analyse the student’s opinion about the activity. Kahoot results showed that 80 of the students pass the test. On the other hand, based on the results of the survey, the activity proved to be very interesting for the students. The flipped classroom helped them to clarify concepts and many of them considered that having previous theoretical background is important to understand the activity, although it is not essential.
