Histological, haematological, and thyroid hormones toxicity of female rats orally exposed to CuO/ZnO core/shell nanoparticles synthesized by Ar plasma jets.

Advancements in nanomedicine helped scientists design a new class of nanoparticles known as hybrid nanoparticles (core/shell) for diagnostic and therapeutic purposes. An essential requirement for the successful use of nanoparticles in biomedical applications is their low toxicity. Therefore, toxicological profiling is necessary to understand the mechanism of nanoparticles.

Estimation of in vivo toxicity of MgO/ZnO core/shell nanoparticles synthesized by eco-friendly non-thermal plasma technology.

MgO/ZnO core/shell nanoparticles were synthesized using the atmosphere plasma jets technique. The physical properties of the synthesized nanoparticles were investigated by a series of techniques, including X-ray diffraction (XRD), X-ray dispersive spectroscopy (EDS), and transmission electron microscopy (TEM). XRD and EDS analyses confirmed the purity of the nanoparticles synthesized with an average nanoparticle crystallite size of 36 nm.

Evaluation of uranium concentration in the blood breast cancer women with CR-39 detector.

Some governorates of Iraq are considered as uranium-contaminated areas. The spread of cancerous tumors injuries was recorded in different parts of Iraq at very high rates. As cancer is closely related to high level of uranium in the blood, this study was conducted on women with breast cancer to evaluate the uranium concentrations in their blood.

Assessment of uranium concentration in blood of Iraqi females diagnosed with breast cancer.

Cancer is a widespread significant health problem in Iraq and contributes 11% to total deaths. Throughout the Gulf Wars of 1991 and 2003, about 1200 tons of ammunition were dropped around Iraq. After the wars, cancer incidence in Iraq is about 7,000 to 8,000 cancers cases per year, and the overall incidence of lymphoma, leukemia, breast cancer, and lung cancer has increased twofold and even tripled, as compared to the time before the wars.

Uranium, Thorium, Potassium, and Cesium Radionuclides Concentrations in Desert Truffles from the Governorate of Samawah in Southern Iraq.

Studies have been conducted in some southern Iraqi governorates to measure the radioactive contamination in the soil and have revealed that these areas are contaminated with radioactive materials. In these test sites, where many military operations have been conducted and that may have been affected by the Chernobyl accident, pollution and its impact on the truffle crop have been examined. Truffles are fungi that grow in the ground and can be contaminated by radiation from polluted soil.

The Activity Concentrations and Radium Equivalent Activity in Soil Samples Collected from the Eastern Part of Basrah Governorate in Southern Iraq.

Clay soil samples (0, 30, and 60 cm depths) were collected from two districts (Abu Al Khasib and Ad Dayr) in Basrah governorate in southern Iraq for gamma-ray spectroscopy. The activity concentrations for natural existing radionuclides in 18 soil samples were measured using high-purity germanium detector HPGe. From the obtained results of -ray spectroscopy, the U activity concentrations were found to be ranging from 2.
