SA-ß-galactosidasa como predictor de senescencia celular del epitelio superficial ovárico y factores de riesgo de cáncer de ovario

Introducción: la tercera causa de muerte ginecológica es cáncer de ovario (CO), la detección temprana es fundamental para reducir mortalidad. El objetivo es establecer asociación entre senescencia en cultivos de tejido epitelial de ovario (ESO) mediante expresión de enzima ßgalactosidasa/normalizada y factores de riesgo reconocidos para CO. Métodos: estudio descriptivo observacional con fase exploratoria de datos proporcionados por “TRF2” segunda fase; muestra 29 tejidos de mujeres con ooforectomia condiciones benignas, analizadas estadísticamente con confianza del 95%, software SPSS versión 17, datos se presentan con desviación estándar, promedio, mediana (velocidad de crecimiento celular y ßgal/Normalizada) y porcentajes (variables categóricas). Realizo comparación con t-student, test de normalidad con Shapiro Wilks y asociación mediante análisis multivariado. Resultados: encuentra evidencia estadísticamente significativa (p < 0,05) para asociación entre antecedente familiar de otros tipos de cáncer con cáncer gástrico (IC95%: -2,84, -0,23) y cáncer de seno (IC95%: -3,39, -0,38); no tener régimen de afiliación en salud (vinculado) (IC95%: -3,67 -0,014); uso de método anticonceptivo de barrera (IC95%: -3,95, -0,07); consumo de embutidos (IC95%: -3,30, -0,21) y enlatados (IC95%: -3,62, -0,030) 1 a 3 veces/semana y consumo de alcohol (IC95%: -2,33, -0,33) con aumento expresión ßgal/Normalizada. Discusión: senescencia es antitumorigénica a edades tempranas, en avanzadas es protumorigénica, cuando hay mucha acumulación de células senescentes en tejido, éstas cambian su perfil senector produciendo sustancias que afectan a las vecinas, lo que lleva a transformación tumoral. Esta investigación es novedosa.

The International Student Experience at the University of Southampton

This video highlights aspects of the lives of international students at UG, PGT and PGR levels from all 3 faculties. It shows them responding to a range of authentic scenarios about the experiences and challenges of being an international student at the University of Southampton in the early 21st century from their perspective. The overall objective of this short film therefore is to capture experiences and viewpoints of international students currently at the University. By viewing this video, it is hoped that staff will be able to gain a better understanding and appreciation of what their international students are feeling and facing at various points along their student life cycle.

A Day in the Life of a Student (2006)

This is self playing Powerpoint with sound, which was made by researchers in Learning Technology, in 2001, suggesting what the life of a student in 2006 might look like. It is interesting to see how far we have come (or not come) in the time since.

Student expectations and perceptions of feedback in Chemistry

These documents show the outcomes of surveys conducted by David Read in the School of Chemistry to find out about our students' expectations and perceptions of feedback, with a view to enhancing our provision and ensuring that student learning is maximised.
