Cutaneous lymphomas are particularly radiosensitive and amenable to palliative radiation therapy. Total skin electron beam therapy (TSEB) is effective for palliation of Sézary syndrome and cutaneous T-cell lymphoma with large body surface area involvement. Focal radiation therapy is often used for treatment of localized disease. Treatment of cutaneous T-cell lymphoma can often pose technical ch...

EBRT: electron beam radiation therapy GRT: Grenz ray therapy HHD: Hailey-Hailey disease INTRODUCTION Hailey-Hailey disease (HHD), or familial benign chronic pemphigus, is an autosomal dominant genodermatosis. In this condition, dysregulation of intracellular calcium homeostasis leads to impaired desmosome function and suprabasilar acantholysis of the epidermis. Clinically, this condition presen...

Gold (Au) nanoshells with solid silica cores have great potential for cancer photothermal therapy. However, this nanostructure cannot carry enough drugs. Here, we report a Au nanoshell with a hollow silica core for drug loading and cancer therapy. The silica shells were synthesized using nanoliposome templates, and then Au nanoshells were grown on the outer surface of the silica shells. Transmi...

Pagetoid reticulosis, also known as Woringer-Kolopp disease, is a rare variant of cutaneous T-cell lymphoma usually presenting as an isolated patch or plaque on the extremities. Immunohistochemical staining of T-cell markers can be variable, but as the name implies the epidermotropic lymphocytes consistently display a "pagetoid" appearance. The following case demonstrates clearance of this cond...

the binding, release and oxidation of oxygen occur at the heme group iron ion. hemoglobinoxidation-reduction studies have been previously performed using spectroelectrochemistry (sec) andhave provided insight into the hemoglobin electron transfer process and more specifically, into theheme group electronic factor and subunit interaction influences. in this study, the number of fullerenecarbon a...

Electron beam radiation therapy is used extensively for treating head and neck cancers to avoid the irradiation of the spinal cord. It is also used for treating chest wall malignancies to limit the irradiated volume of lungs. Calculating the dose distribution from an electron field is quite complicated because of the multiple scattering, especially in the presence of internal heterogeneities [1...

The development of a new depth-dose measuring device for electron beam therapy is described. The device employs plastic scintillating fiber detectors inserted in a polymethylmethacrylate (PMMA) phantom in line along an incident electron beam. Output photons from a fiber, the number of which is proportional to the absorbed dose at each depth of the phantom, were converted to an electric signal w...

Introduction: Radiation therapy using electron beams is a promising method due to its physical dose distribution. Monte Carlo (MC) code is the best and most accurate technique for forespeaking the distribution of dose in radiation treatment of patients.Materials and Methods: We report an MC simulation of a linac head and depth dose on central axis, along with profile calculations. The purpose o...

Objective- Investigating of the isolation, culture, differentiation potential and electronic microscopic characterization of canine periodontal ligament stem cells (PDLSCs). Design- Experimental in vitro study Animals- Four intact, male, mongrel dogs, 8-10 months-old were selected to collect PDLSCs from their teeth. Procedures- The dogs were anesthetized and the first maxillary and mandibula...
