A novel X-linked combined immunodeficiency disease was found in five living males in an extended family in the United States. The age of the affected males ranged from 2.5 to 34 yr. The most prominent clinical abnormalities were a paucity of lymphoid tissue; recurrent sinusitis, otitis media, bronchitis, and pneumonia; severe varicella; and chronic papillomavirus infections. The principal immun...
متن کاملLithium diaquanickel(II) catena-borodiphosphate(V) monohydrate
The title borophosphate LiNi(H(2)O)(2)[BP(2)O(8)]·H(2)O was synthesized under hydro-thermal conditions. The crystal structure is isotypic with the Mg analogue and features helical [BP(2)O(8)](3-) borophosphate ribbons, constructed by BO(4) (2 symmetry) and PO(4) tetra-hedra. The borate groups share all their oxygen apices with adjacent phosphate tetra-hedra. The ribbons are connected via Ni(2+)...
متن کاملPreparation of Nanohybrid CuO-Fe3O4 /Zeolite Nanocomposite as Potential Adsorbent for Toxic As (V) and Pb(II) from Water Solution.
ABSTRACT In this paper, novel Nanohybrid CuO-Fe3O4/Zeolite nanocomposites (HCFZ NCs) have been synthesized to improve the adsorption capacity and activity for removing the Arsenic and Lead cations from the contaminated water solutions. The nanohybrid 4, 10, and 20 -HCFZ NC samples were investigated by XRD, FT-IR, TEM, FESEM, EDX, and BET. The characterization results of these catalysts confirm...
متن کاملRemoval of As(V), Cr(VI) and Pb(II) from aqueous solution using surfactant-modified Sabzevar nanozeolite
The pollution of water environments is a challenging issue especially in developing countries. Contamination of drinking water with heavy metals has been reported in many parts of the world. Arsenic, chromium and lead are dangerous heavy metals and also common contaminants of drinking water. In this study, the capacity and performance of the surfactant-modified Sabzevar natural nanozeolite (SMS...
