Neurodevelopmental Outcome of Childhood Cancer Survivors Treated at the Eric Williams Medical Sciences Complex.

Objective: To investigate the neurodevelopmental outcome of childhood cancer survivors treated at the Eric Williams Medical Sciences Complex (EWMSC).

Methods: Study participants were children treated at EWMSC from January 2003 to March 31, 2012 for various childhood cancers. All had completed treatment and were in remission.

Analysis of imatinib and sorafenib binding to p38alpha compared with c-Abl and b-Raf provides structural insights for understanding the selectivity of inhibitors targeting the DFG-out form of protein kinases.

Protein kinases c-Abl, b-Raf, and p38alpha are recognized as important targets for therapeutic intervention. c-Abl and b-Raf are major targets of marketed oncology drugs Imatinib (Gleevec) and Sorafenib (Nexavar), respectively, and BIRB-796 is a p38alpha inhibitor that reached Phase II clinical trials. A shared feature of these drugs is the fact that they bind to the DFG-out forms of their kinase targets.

Comparison of metal-dependent catalysis by HIV-1 and ASV integrase proteins using a new and rapid, moderate throughput assay for joining activity in solution.

Background: HIV-1 integrase (IN) is an attractive target for the development of drugs to treat AIDS, and inhibitors of this viral enzyme are already in the clinic. Nevertheless, there is a continuing need to devise new approaches to block the activity of this viral protein because of the emergence of resistant strains. To facilitate the biochemical analysis of wild-type IN and its derivatives, and to measure the potency of prospective inhibitory compounds, a rapid, moderate throughput solution assay was developed for IN-catalyzed joining of viral and target DNAs, based on the detection of a fluorescent tag.

Oligonucleotide-based assays for integrase activity.

Oligonucleotide assays have been invaluable for elucidation of the molecular mechanisms of retroviral integrases. A suite of rapid and sensitive fluorescence assays to measure the DNA binding, processing, and joining activities of integrase (IN) is described here. The assays are especially useful for characterizing the major activities of the enzyme, and for handling large numbers of samples efficiently.

The neurodevelopmental abilities of very-low-birthweight children in Trinidad, West Indies.

Neurodevelopmental abilities of 33 very-low-birthweight (VLBW) Trinidadian children and randomly selected matched pairs of classmates who were of normal birth weight were tested in 1998 at ages 68-88 months, using the McCarthy Scales of Children's Abilities. The 1 min Apgar score was significantly lower in the VLBW children, 6.5 (SD 1.
