The parasitoid Psyttalia humilis (Silvestri) was reared on Mediterranean fruit fly, Ceratitis capitata (Wiedemann), third instars irradiated at 0-70 Gy at the USDA, APHIS, PPQ, Moscamed biological control laboratory in San Miguel Petapa, Guatemala, and shipped to the USDA, ARS, Parlier, CA. Irradiation dose did not affect the parasitoid's offspring sex ratio (53-62% females), percentage of une...

conclusions considering the high level of artificial colors found in the samples of this study, preventive measures are essential. results the results showed that several products did not meet the standards. fifty-six out of the 70 (80%) samples examined in the study, namely sunset yellow (60%), tartrazine (57.1%), quinoline yellow (44.28%), azorubine (28.57%), ponceau 4r (8.57%) and allura red...

background: cytotoxic therapy can lead to prolonged azoospermia or even sterility. in the present study, we investigated the morphological changes of mouse testes after gamma-radiation. methods: after anaesthetizing of nmri mice, testes and their surrounding tissues were irradiated using a cobalt therapy machine. four experimental groups were irradiated with fractionated doses of: 1.5+8, 1.5+12...

radiation-related wounds challenge surgeons in all disciplines of surgery. wound-healing complications are commonplace, and solutions for reconstruction are limited. muscle and musculocutaneous flaps have improved this situation. but the question is, does previous radiation of the muscle to be transposed affect the outcome? 143 consecutive previously irradiated patients treated with muscle or m...

background: similar to the thermoluminescence (tl) spectra, the optical parameters variations can also be used in tl crystals for dosimetry purposes. these optical parameters can include absorption, transmission and reflection coefficients. materials and methods: single crystals of kbr and kcl which have been used in this research were grown from laboratory grade extra pure precursor powders. c...

Abstract Background The use of X-ray irradiation in the control maize weevil, Sitophilus zeamais Motschulsky (Coleoptera: Curculionidae) infesting stored was tested at 60, 70 and 80 KeV as part international concerted efforts to save production enhance food security. Investigations were done laboratory mean temperature relative humidity 29.2 °C 75.7%, respectively using three varieties maize. p...

The choice to examine DNA seems obvious, since DNA is a sensitive cellular target to irradiation and the changes in DNA are responsible for many effects observed in irradiated foods, such as the inactivation of microorganisms, elimination of insects, inhibition of sprouting in bulbs and tubers and delay of ripening in several fruits1. Therefore, these changes in DNA should be discernible in mic...

Two trials were conducted to determine the effects of irradiation of individual ingredients or the whole diet on growth performance in nursery pigs. The response was similar for both trials with pigs fed diets containing irradiated spray-dried animal plasma or soybean meal having increased (P<0.05) ADG compared with pigs fed the control diet with no irradiated ingredients or the complete diet t...
