Toll like receptor 4 (TLR4) expression on peripheral blood mononuclear cells (PBMCs) among patients with Graves disease

Autor: Youssra G, Mahfouz, Salwa S, Hosny, Mohamed N, Farres, Dina S, Sheha, Dina A, Marawan, Hossam M, ElKady

Publikováno v: The Egyptian journal of immunology. 28(4)

Graves disease (GD) is a multifactorial disease due to multiple environmental and genetic factors as well as immune malfunction. Human Toll-like receptors (TLRs) play a key role in activating innate and adaptive immune cells. Their role in modulating

Bioleaching of uranium from el-sella ore material using epicoccum nigrum

Autor: Shimaa S. Hussien, Mohamed G. Mahfouz, Abdou A El Mougith, Wesam A. Hassanien, Azhar M Elsayad

Publikováno v: IOP Conference Series: Materials Science and Engineering. 975:012021

Uranium (U) is one of the strategic elements and essential for many applications as a fuel in nuclear power plants and nuclear weapons. Bioleaching of uranium was carried out with Epicoccum nigrum isolated from El-Sella ore material. El-Sella area is
