CXCR4 is the receptor of CXC chemokine SDF-1 and may play a role in the homing of hematopoietic stem cells. We have investigated the CXCR4 gene expression during ATRA treatment in acute promyelocytic leukaemia (APL) patients. APL is a characteristic disorder with a specific translocation between PML and RAR alpha genes on chromosome 15 and 17. ATRA-induced differentiation of APL cells is strict...

BACKGROUND Recent studies have reported blood levels of polybrominated diphenyl ethers (PBDEs) in the U.S. population. Information about neonatal levels and about the relationship to polychlorinated biphenyls (PCBs) exposures is limited. OBJECTIVES The objective was to characterize levels and determinants of fetal exposure to PBDEs and PCBs among newborns from Baltimore, Maryland. METHODS W...

An investigation of the structure and dynamics of the high-energy ionic liquid, 1-hydroxyethyl-4-amino-1,2,4-triazolium nitrate (HEATN), was undertaken. Both experimental and computational methods were employed to understand the fundamental properties, characteristics, and behavior of HEATN. The charge separation, according to the electrostatic potential derived charges, was assessed. The MP2 (...
