The authors studied the effect of gamma radiation and submaximum physical exercise on adenosine-5'-triphosphate (ATP), adenosine-5'-diphosphate (ADP) and adenosine-5'-monophosphate (AMP) contents in erythrocytes of healthy males. Twenty one men aged 20-22 years were examined. They underwent physical exercise at doses of 2 w/kg body weight for 15 min. Erythrocytes were exposed to gamma radiation (500 gy doses) from 60Co source. The concentration of adenine nucleotides in erythrocytes was measured by the Boehringer Mannheim tests. The submaximum physical exercise was found to decrease ATP content and to to increase ADP and AMP in erythrocytes. Gamma radiation at 500 Gy dose was found to decrease ATP concentration in erythrocytes both at rest and after submaximum exercise and to increase AD content. It was revealed that AMP content increased at rest and decreased after submaximum exercise in irradiated erythrocytes.

Background: Even a gross total resection of a benign epidermoid tumor (ET) carries a high risk of recurrence. The management strategy mostly involves redo surgical excision but at a significant cost of morbidity and mortality. The role of adjuvant radiation therapies in this scenario is still undefined.

Pancreatic ductal adenocarcinoma (PDAC) is notably resistant to conventional chemotherapy and radiation treatment. However, clinical trials indicate that carbon ion radiotherapy (CIRT) with concurrent gemcitabine is effective for unresectable locally advanced PDAC. This study aimed to identify patient characteristics predictive of CIRT response.

Background: Tremor, either in patients with Essential Tremor (ET) or Parkinson's disease (PD), constitutes the most common movement disorder. Stereotactic radiosurgery using Gamma Knife (GK) and linear accelerator (LINAC) systems, is an effective, incisionless treatment modality for ET and PD. Although these technologies have been used clinically since the 1990's, most studies have focused on GK, and efficacy, safety and time to treatment effect (latency) of GK and LINAC have not been compared.
