OBJECTIVES: The purpose of this study was to assess the characteristics of long-stay patients in contemporary state psychiatric hospitals and to identify factors representing possible barriers to alternative placements for these patients. METHODS: All patients in inpatient units of the Massachusetts Department of Mental Health who had been hospitalized for at least three years as of April 1, 1999, were assessed by their treatment teams with a standardized data collection instrument. Domains assessed included medical problems, need for nursing care, psychiatric diagnosis, and history of problematic behaviors. RESULTS: The 330 individuals identified as long-stay patients had an array of medical …

BACKGROUND: Alpha-galactosylceramide (alpha-GalCer) is an invariant natural killer T (iNKT) cell ligand that prevents type 1 diabetes in NOD mice. However, alpha-GalCer can activate or suppress immune responses, raising concern about its potential use in human diabetes.

MATERIALS AND METHODS: To evaluate this therapeutic issue further, BBDR and LEW.1WR1 rats were treated with Kilham rat virus (KRV) plus polyinosinic-polycytidylic acid, with or without alpha-GalCer, and followed for onset of diabetes.

RESULTS: alpha-GalCer did not prevent diabetes in inducible rat models. To investigate this discrepancy, we analyzed iNKT cell function. Splenocytes stimulated with alpha-GalCer produced similar levels of IFNgamma in all …

"Ectotherms increase their body temperature in response to ambient heat, thereby elevating their metabolic rate. An often inferred consequence of this is an overall upregulation of gene expression and energetic expenditure, and a concomitant increased production of reactive oxygen species (e. g. superoxide) and, perhaps, a shortened lifespan. However, recent work shows that this may be a superficial interpretation. For example, sometimes a reduced temperature may in fact trigger up-regulation of gene expression. We studied temperature and associated activity effects in male and female Australian painted dragon lizards (Ctenophorus pictus) by allowing the lizards to bask for 4 h versus …
