Background: Phototherapy is a safe and effective treatment modality for skin diseases in children such as psoriasis, atopic dermatitis, pityriasis lichenoides, vitiligo, cutaneous cell lymphoma, rubra pilaris, other disorders. It reported to be with less side effects compare the administration of systemic medicine. Short long term should taken into account when applying this model therapy, espe...

Personal Digital Assistants (PDAs) have become a part of everyday life. DermaMan is a freely available, Java-based, dermatology-specific calculator for handheld devices. It includes modules to compute PASI, MASI, SCORAD, and for calculations related to topical PUVA and Botox (R) administration.

This report is primarily concerned with methods for optical calibration of laser power for continuous wave (CW) light sources, predominantly used in photodynamic therapy (PDT). Light power calibration is very important for PDT, however, no clear standard has been established for the calibration procedure nor the requirements of power meters suitable for optical power calibration. The purposes o...

Incorporation of biquinoline ligands into Ru(II) polypyridyl complexes produces light-activated systems that eject a ligand and photobind DNA after irradiation with visible and near-IR light. Structural analysis shows that distortion facilitates the photochemistry, and gel shift and cytotoxicity studies prove the compounds act as anti-cancer photodynamic therapy (PDT) agents in the tissue penet...

As breast cancer is diagnosed in over a million patients a year it is a significant oncological issue. Treatment paradigms have shifted to emphasize breast preservation protocols. However, due to a lack of equipment and facilities this option is only rarely offered to poverty stricken patients and those in the developing world. Photodynamic therapy may play a role in allowing for greater breast...

We test whether coherent control methods based on ultrashort-pulse phase shaping can be applied when the laser light propagates through biological tissue. Our results demonstrate experimentally that the spectral-phase properties of shaped laser pulses optimized to achieve selective two-photon excitation survive as the laser pulses propagate through tissue. This observation is used to obtain fun...
