Photodynamic Therapy (PDT) with 5-aminolevulinic acid (ALA) is known to be limited for applications in tumours of large volume mainly due to the limited penetration of topical photosensitization. The results show that ...

Background: In this study, we applied ultra-short time series of interbeat intervals (RR-intervals) to evaluate heart rate variability through default chaotic global techniques with the purpose of discriminating obese ...

We present a theoretical study of the ionization of hydrogen atoms as a result of the interaction with an ultrashort external electric field. Doubly-differential momentum distributions and angular momentum distributions ...

Electron emission coming from the valence band of metal surfaces due to grazing incidence of  high frequency ultrashort laser pulses is studied. We introduce a distorted-wave method, named impulsive jellium-Volkov (IJV) ...

Electron emission from metal surfaces produced by short laser pulses is studied within the framework of the distorted-wave formulation. The proposed approach, named surface-Volkov (SV)approximation, makes use of  the ...

AimThe aim of the present study was to develop and validate an ultra-short Spanish version of the Oral Health Impact Profile (OHIP) in an elderly Chilean population. MethodsThe OHIP-49Sp was applied to 490 older adults, ...
