Half-times of irradiation recovery in accelerated partialbreast irradiation: Incomplete recovery as a potentially dangerous enhancer of radiation damage

Recovery of spermatogenesis after total-body irradiation.

criteria and 40% in the best schedule (5-day intravenous). This compares favorably with prior experiences with decitabine and 5-azacitidine (CR rates, 6%-20%).4,5 Also, decitabine was less toxic than 5-azacitidine in relation to nausea/vomiting and local skin reactions (pain and induration in 5%-10% of patients on 5-azacitidine). The incidence of 65% of hospitalization is cumulative. As one del...

Human cell recovery after microwave irradiation

Cells of human buccal epithelium of 6 male donors were exposed to microwave radiation (frequency f=36,64 GHz, power density E=10, 100, and 400 µW/cm 2). Exposure time in all experiments was 10 seconds. Heterochromatin was stained by 2% orcein in 45 % acetic acid. The stainability of cells with trypan blue (0,5 %) and indigocarmine (5 mM) after 5 min of staining was investigated. Irradiation ind...

RADIATION DAMAGE IN OXIDESElectron irradiation damage in MgO

MgO crystals have been irradiated and examined in a high voltage electron microscope at temperatures from 300 to 1100 K and voltages up to 650 kV. An observed decrease in threshold displacement energy with increasing voltage is interpreted in terms of thermally-activated break-up of close Mg Frenkel pairs. k t high doses and temperatures, perfect 112 ( 110 ) ( 110 ) interstitial edge dislocatio...

Over-expression of CXCR4, a stemness enhancer, in human blastocysts by low level laser irradiation

The key role of chemokine receptor CXCR4 in the maintenance of stemness property of stem cells has been shown recently. The low level laser irradiation (LLLI) is being used currently in a wide variety of clinical cases as a therapeutic tool for wound healing, relieving pain and destroying tumor cells. The aim of this study was to evaluate the effect of LLLI mimicking low level laser therapy (LL...
