in this paper, we have studied the electrical properties of the randomly distributed metallic (co and fe) nano/ micro wires on silicon substrate. deposition was carried out potentiostatically into the pores of the track-etch polycarbonate membrane spin coated onto the si substrate. spin coated films were irradiated with 150mev ni (+11) ions at a fluence of 8e7 ions/cm2, followed by uv irradiati...

background: this cross sectional study was conducted to evaluate the effect of &gamma-rays; and electron-beam irradiation with a commercial toxin binder-milbond-tx on the performance, feed components, and meat quality of japanese quails challenged with aflatoxin b1. methods: overall, 168 one-d-old chicks (japanese quails) were allocated to eight treatments with three replicates based on a compl...

background: radiotherapy has many side effects on fertilization in young women. radiation can lead to ovarian failure in women who underwent abdomen or pelvic radiotherapy. objective: this study helps us to investigate ovarian response of nmri female mice to ovarian stimulating hormones (pmsg, hcg) after whole-body gamma irradiation. materials and methods: 45 pregnant mice were divided into two...

the gamma irradiation has been used for end sterilization of allograft bones and its effects with a 25 kgy dosage on the osteoinductive properties of demineralized bone allograft powder was studied. this work carried out using an experimental method in an animal model. in this study the demineralized bone allograft powder which had been sterilized and prepared with gamma irradiation in a 25 kgy...

the effect of 10 and 25 kgy ?-irradiation on penicillin g plus procaine and sodium ampicillin has been assessed by different chemical and microbiological analytical methods. according to the chemical results obtained, the antibiotics showed a slight reduction in doses applied but the microbiological assays revealed that the activity of irradiated antibiotics did not reduce. microbiological stud...

background: genome instability is a main cause of chromosomal alterations in both somatic and germ cells when exposed to environmental, physical and chemical genotoxicants. germ cells especially spermatozoa are more vulnerable to suffering from dna damaging agents during spermatogenesis and also more potent in transmitting genome instability to next generation. methods: to investigate the effec...

in spite of the technologies developed during the last decade, the level of food loss is still high and is reported in many countries. according to the united nations, more than 30 per cent of the mortality rate world-wide is caused by alimentary diseases. the desire of most countries to make food safer for consumption requires better food preservation and production techniques. in this regard,...

background: the aim of this study was to evaluate the radioprotective capacity of some novel aminoalkylated dithiocarbamic acid potassium salts against γ-irradiation in mice. materials and methods: eight compounds containing 2-aminoethyl-, 3- aminopropyl-, 4-aminobutyl-, 5-aminopentyl-, 6- aminohexyl-, 7-aminoheptyl-, 8-aminooctyl and 9- aminononyl of dithiocarbamate derivatives were prepared. ...

In this study, we evaluate the attenuation of the dose due to barium-impregnation in the region between the surface of an electronic brachytherapy (EBT) balloon applicator for accelerated partial breast irradiation (APBI) and the prescription point at 1 cm depth in tissue. To perform the study, depth dose curves were calculated using a general purpose multi-particle transport code (FLUKA) for a...

PURPOSE There are multiple current strategies for breast radiotherapy (RT). The alignment of physician practice patterns with best evidence and patient preferences will enhance patient autonomy and improve cancer care. However, there is little information describing patient preferences for breast RT and physician practice patterns. METHODS AND MATERIALS Using a reliable and valid instrument, ...
