The concept of CNS preventive therapy in childhood all is based on the assumption that undetectable CNS leukemia is present in most patients at the time of diagnosis, residing in that "sdnctuary site" protected by the blood-brain barrier from cytotoxic concentrations of most systemically ad­ministered antileukemic agents. Studies in the 1960s demonstrated that administration of 2400 rad cranial...

Emerging pollutants are an increasing problem in wastewater globally. Bisphenol A (BPA) is one compound belonging to this group. This work proposes the study of employment several metal-supported (2 wt. %) carbon nanospheres (CNS) for BPA degradation by catalytic wet-air oxidation. Several techniques were used catalyst characterization: thermogravimetry, X-ray diffractometry (XRD), Fourier tran...

Listeriosis is one of the CNS inflammatory diseases which is happened majority in the form of sporadic. Listeriosis is ingested with the food. Infection occurrence in an exposed person depends on the number of organisms ingested, the virulence of the organisms strain and the individual condition. It is known that Listeriosis has decisive importance as an infection which the cellular immunodefen...

Two cases of multiple concomitant CNS tumors of different histologic types are presented.  One was a case of neurofibromatosis type 2 (NF2) with 6 CNS tumors, and the other a case of 4 CNS tumors without any evidence of NF. To our knowledge, there is no report of concomitant occurrence of 6 CNS tumors in the medical literature. Neuroradiological  and operative findings are illustrated and discu...

Abstract Central nervous system (CNS) involvement remains a challenge in the diagnosis and treatment of acute lymphoblastic leukemia (ALL). In this study, we identify CD79a (also known as Ig?), signaling component preB cell receptor (preBCR), to be associated with CNS-infiltration –relapse B-cell precursor (BCP)-ALL patients. Furthermore, show that downregulation hampers engraftment cells diffe...
