A largely herbarium-based study was undertaken to reassess the status of Elymus athericus (Link) Kerguélen (Sea Couch) and three coastal hybrids E. x drucei (Stace) Stace, laxus (Fr.) Melderis & D.C. McClint. obtusiusculus (Lange) in Scotland. None previous records could be confirmed for country. Verified are detailed listed each relevant vice-county.

The GammaPlan treatment planning system does not account for the leakage and scatter dose during APS repositioning. In this study, the dose delivered to the target site and its periphery from the defocus stage and intershot couch transit (couch motion from the focus to defocus position and back) associated with APS repositioning are measured for the Gamma Knife model 4C. A stereotactic head-fra...

A hundred years after psychoanalysis was introduced, neuroscience has taken a giant step forward. It seems nowadays that effects of psychotherapy could be monitored and measured by state-of-the art brain imaging techniques. Today, the psychotherapy is considered as a strategic and purposeful environmental influence intended to enhance learning. Since gene expression is regulated by environmenta...

Treatment of patients with multiple brain metastases using a single-isocenter volumetric modulated arc therapy (VMAT) has been shown to decrease treatment time with the tradeoff of larger low dose to the normal brain tissue. We have developed an efficient Projection Summing Optimization Algorithm to optimize the treatment geometry in order to reduce dose to normal brain tissue for radiosurgery ...

Aim: The present study is devoted to evaluate the dose at different points defined on the patient using semiconducting diodes and thermoluminescence detectors to excute verification of the dose at these relevant points calculated by means of movement couch and Beam Zones method of the Total Body Irradiation Technique. Material and Method: In this technique; 11 patients using 6 MV X-ray in the (...

We have constructed a computer controlled translational couch to administer total body irradiation reproducibly and safely. The system has replaced the previous stationary anterior-posterior technique in our institution and 30 plus patients have been treated with it so far. In this technique, patients comfortably lie on a couch in supine and prone positions and are transported slowly through a ...
