Response of Ciliated Cells During Irradiation at Different Dose Rates

Unexpected Behaviour of Polystyrene Based Scintillating Fibers During Irradiation at Low Doses and Low Dose Rates

Study of cancer cells response row K562 to Low-Dose- Beta irradiation and determination of absorbed dose using Monte Carlo method

Introduction: Cancer is, in essence, a genetic disease and is the second leading cause of death globally. Fortunately, many common types of cancer are treatable if detected early and of course there are many medications and treatments available today. Among the new methods to treat cancer, radiotherapy seems to be hopeful in patients with malignancies. This work investigates th...

Evaluation of Thyroid Gland Irradiation in Women with Breast Cancer during Radiotherapy with different Radiation Energies at Supraclavicular Region

Introduction: During treatment of breast cancer, Radiotherapy to the Supraclavicular fossa region results in absorption of radiation by the thyroid gland and consequently leads to hypothyroidism in 40% of patients. The aim of this study was to compare thyroid gland radiation absorption during radiotherapy with different anterior-posterior beam radiation of 6-15 and 15-15 MV pho...

Response of nasal ciliated cells of the guinea-pig during allergic reactions in human blood.

Nasal mucosal samples from thirty-five guinea-pigs were placed in a chamber, containing the medium RPMI 1640. Ciliary activity (beats.s-1) of the most active cell in each mucosal culture was measured using a photoelectric method. The RPMI 1640 was then replaced by 2 ml of RPMI 1640 and 1 ml of heparinized human blood from a non-allergic patient, with a ragweed-sensitive nasal allergy, or patien...

Survival of tumor cells after proton irradiation with ultra-high dose rates

BACKGROUND Laser acceleration of protons and heavy ions may in the future be used in radiation therapy. Laser-driven particle beams are pulsed and ultra high dose rates of >10⁹ Gy s⁻¹ may be achieved. Here we compare the radiobiological effects of pulsed and continuous proton beams. METHODS The ion microbeam SNAKE at the Munich tandem accelerator was used to directly compare a pulsed and a co...
