Genetic aberrations in glioblastoma multiforme: translocation of chromosome 10 in an O-2A-like cell line

We have examined the genetic aberrations in two near-diploid glioblastoma multiforme cell lines that appear to have arisen from different glial lineages. One cell line, Hu-O-2A/Gb1, expresses antigens and metabolic profiles characteristic of the oligodendrocyte-type-2 astrocyte (0-2A) lineage of the rat central nervous system. This line generates, in vitro, cells with characteristics of 0-2A progenitor cells, oligodendrocytes and astrocytes. The second cell line, IN1434, is derived from an astrocyte or a precursor cell restricted to astrocytic differentiation. In Hu-O-2A/Gb1 the sole homologue of chromosome 10 is disrupted at band 10p11–12.1 by translocation with chromosomes X and 15. The translocation breakpoint is localized between genetic markers D10S2103 and [D10S637, D10S1962, D10S355]. Other aberrations include a 5;14 translocation, deletion of the long and short arms of chromosome 16 and loss of one copy of the CDKN2 gene. IN1434 cells share some cytogenetic abnormalities with Hu-O-2A/Gb1 cells, despite their apparent derivation from a different biological origin, but also have translocations involving the long and short arms of chromosome 1 and the long arm of chromosome 7, and deletion of chromosome 13 at bands 13q12–21. © 1999 Cancer Research Campaig

Genetic Diversity of Staphylocoagulase Genes (coa): Insight into the Evolution of Variable Chromosomal Virulence Factors in Staphylococcus aureus

. Although SCs have been classified into 10 serotypes based on the differences in the antigenicity, genetic bases for their diversities and relatedness to chromosome types are poorly understood. type except for the cases of CC1 and CC8, which contained two and three different SC types, respectively. loci, resulting in the carriage of the combinations of allotypically different important virulence determinants in staphylococcal chromosome

Postpartum depression on the neonatal intensive care unit: current perspectives

Noor N Tahirkheli,1 Amanda S Cherry,1 Alayna P Tackett,2 Mary Anne McCaffree,3 Stephen R Gillaspy11Section of General and Community Pediatrics, Department of Pediatrics, University of Oklahoma Health Sciences Center, Oklahoma City, OK, USA; 2Department of Psychology, Oklahoma State University, Stillwater, OK, USA; 3Section of Neonatal-Perinatal Medicine, Department of Pediatrics, University of Oklahoma Health Sciences Center, Oklahoma City, OK, USAAbstract: As the most common complication of childbirth affecting 10%–15% of women, postpartum depression (PPD) goes vastly undetected and untreated, inflicting long-term consequences on both mother and child. Studies consistently show that mothers of infants in the neonatal intensive care unit (NICU) experience PPD at higher rates with more elevated symptomatology than mothers of healthy infants. Although there has been increased awareness regarding the overall prevalence of PPD and recognition of the need for health care providers to address this health issue, there has not been adequate attention to PPD in the context of the NICU. This review will focus on an overview of PPD and psychological morbidities, the prevalence of PPD in mothers of infants admitted to NICU, associated risk factors, potential PPD screening measures, promising intervention programs, the role of NICU health care providers in addressing PPD in the NICU, and suggested future research directions.Keywords: neonatal intensive care unit, postpartum depression, mother

Postpartum depression screening in the Neonatal Intensive Care Unit: program development, implementation, and lessons learned

Amanda S Cherry,1 Ryan T Blucker,1 Timothy S Thornberry,2 Carla Hetherington,3 Mary Anne McCaffree,3 Stephen R Gillaspy1 1Department of Pediatrics, Section of General and Community Pediatrics, University of Oklahoma Health Sciences Center, Oklahoma City, OK, 2Department of Psychology, Morehead State University, Morehead, KY, 3Department of Pediatrics, College of Medicine, University of Oklahoma, Oklahoma City, OK, USA Objective: The aims of this project were to describe the development of a postpartum depression screening program for mothers of infants in the Neonatal Intensive Care Unit and assess the implementation of the screening program. Methods: Screening began at 14 days postpartum and was implemented as part of routine medical care. A nurse coordinator facilitated communication with mothers for increasing screen completion, review of critical self-harm items, and making mental health referrals. During the 18-month study period, 385 out of 793 eligible mothers completed the screen. Results: Approximately 36% of mothers had a positive screen that resulted in a mental health referral and an additional 30% of mothers had screening results indicating significant symptoms. Conclusion: Several barriers were identified, leading to adjustments in the screening process, and ultimately recommendations for future screening programs and research. Development of a postpartum depression screening process in the Neonatal Intensive Care Unit involves support, training, implementation, and coordination from administrators, medical staff, new mothers, and mental health specialists. Several predictable challenges to program development require ongoing assessment and response to these challenges. Relevance: This study highlights the expanding role of the psychologist and behavioral health providers in health care to intervene as early as possible in the life of a child and family with medical complications through multidisciplinary program development and implementation, as well as key considerations for institutions initiating such a program.

The contribution of maternal psychological functioning to infant length of stay in the Neonatal Intensive Care Unit

Illness severity was assessed with the Clinical Risk Index for Babies (CRIB).Results: Postpartum depression was not significantly correlated with LOS, but was significantly correlated with trait anxiety (r=0.620), which was significantly correlated with LOS (r=0.227). Among mothers with previous mental health history, substance abuse history and CRIB score were the best predictors of LOS. For mothers without a prior mental health issues, delivery type, stress associated with infant appearance, and CRIB scores were the best predictors of LOS. In this group, LOS was found to increase on average by 7.06 days per one unit increase in stress associated with infant appearance among mothers with the same delivery type and CRIB score.Conclusion: Significant correlations of trait anxiety, stress associated with infant appearance, and parental role with LOS support the tenet that postpartum psychological functioning can be associated with NICU LOS.

Changing implicit attitudes toward smoking: results from a web-based approach-avoidance practice intervention

Implicit attitudes have been shown to predict smoking behaviors. Therefore, an important goal is the development of interventions to change these attitudes. This study assessed the effects of a web-based intervention on implicit attitudes toward smoking and receptivity to smoking-related information. Smokers (N=284) were recruited to a two-session web-based study. In the first session, baseline data were collected. Session two contained the intervention, which consisted of assignment to the experimental or control version of an approach-avoidance task and assignment to an anti-smoking or control public service announcement (PSA), and post-intervention measures. Among smokers with less education and with plans to quit, implicit attitudes were more negative for those who completed the approach-avoidance task. Smokers with more education who viewed the anti-smoking PSA and completed the approach-avoidance task spent more time reading smoking-related information. An approach-avoidance task is a potentially feasible strategy for changing implicit attitudes toward smoking and increasing receptivity to smoking-related information
