Abstract

Highlights: [•] Silica microspheres have been located on the surface of glass and glass ceramics samples codoped with Er and Yb. [•] Microspheres act as microlens of the 950nm excitation light resulting in focalized excited regions in the samples with sizes under the micron. [•] Intense red upconversion is achieved in the focalized areas. [•] Microspheres collect the upconversion emission light, scoping with the together microlensing properties an enhancement of the detected signal in a 3x factor. [•] Performed Finite-Difference Time-Domain simulations predict the size of the focalized regions in good agreement with the experimental measurements. [Copyright &y& Elsevier]

17. Lesiones colónicas orgánicas en pacientes con síndrome de intestino irritable: un estudio comparativo

Author

Abstract

Introducción y objetivos: Cualquier síntoma alarmante debe evaluarse cuidadosamente en los pacientes con síndrome de intestino irritable (SII). La colonoscopia es un procedimiento de diagnóstico estándar para evaluar la mucosa del colon y descartar probables patologías responsables de los síntomas de los pacientes. Analizamos los hallazgos colonoscópicos en pacientes con SII y pacientes sin SII.
