Lanthanide scintillators capable of converting the absorbed X-ray photon energy to ultraviolet (UV) or visible light, are emerged as promising nanoprobes for multifunctional diagnosis and deep-tissue antitumor therapy such X-ray-excited fluorescence (XEF) imaging, X-ray-triggered photodynamic (X-PDT), soft X-ray-activated NO gas therapy. Such biomedical tools have potential overcome major chall...

the output of x-ray, especially in the field of required energy for diagnosing the disease is very low (in diagnosing lamps, it is less than 1%). in this kind of lamps the rest of the electrical energy is transformed to heat. this considerable amount of heat induces a myriad of too many limitations in choosing higher levels of radiation, particularly in specialized techniques. this process is t...

Background. Advanced basal cell carcinoma (BCC) is often treated by surgery or X-ray therapy. The consequences of X-ray therapy on the patients' health-related quality-of-life (HRQOL) have so far not been described. Objectives. To quantify quality of life in BCC patients before and after X-ray therapy compared with matched healthy controls. Materials. Twenty-five patients (mean age 69) with BCC...

A local effect model (LEM)-based framework capable of interpolating nanoparticle-enhanced photon-irradiated clonogenic cell survival fraction measurements as a function of nanoparticle concentration was developed and experimentally benchmarked for gold nanoparticle (AuNP)-doped bovine aortic endothelial cells (BAECs) under superficial kilovoltage X-ray irradiation. For three different superfici...

This is a prospective clinical study of 46 ear keloids in 31 patients (with a mean follow-up of 18 months) treated from January 2006 to December 2006 at The Queen Elizabeth Public Hospital, Barbados, West Indies by a single surgeon. The mean age is 21.9 years (range 3-66 years). Seven out of 46 lesions were recurrent lesions following previous surgery. All the lesions were excised surgically (e...
