Spawning Latency Period in Hormonal Induced Reproduction of Snow trout (Schizothorax zarudnyi (Nikolskii, 1897))
Background: The breeding performance is an important parameter to evaluate the breeding success in captive condition. The optimum hormone dose in combination with latency period is desirable for getting best breeding performance in fish. Objectives: <span style="color: win...

متن کاملEstimating the Radiation-Induced Cancer Risks in Pediatric Computed Tomography
Introduction One of the central questions in radiological protection is the magnitude of the risks from low doses of radiation, related to the justification and optimization of the diagnostic medical exposures. Therefore, the aim of this study was to estimate the cancer incidence and mortality risks in children of different ages, sizes, and ethnicities undergoing computed tomography examination...
متن کاملRadiation-induced myocardial perfusion abnormalities in breast cancer patients following external beam radiation therapy
Objective(s): Radiation therapy for breast cancer can induce myocardial capillary injury and increase cardiovascular morbidity and mortality. A prospective cohort was conducted to study the prevalence of myocardial perfusion abnormalities following radiation therapy of left-sided breast cancer patients as compared to those with right–sided cancer. Methods: To minimize potential confounding fact...
متن کاملEpidemiology of radiation-induced cancer.
The epidemiology of radiation-induced cancer is important for theoretical and practical insights that these studies give to human cancer in general and because we have more evidence from radiation-exposed populations than for any other environmental carcinogen. On theoretical and experimental grounds, the linear no-threshold dose-response relationship is a reasonable basis for extrapolating eff...
