Infective juveniles of entomopathogenic nematodes (Steinernema and Heterorhabditis) secrete ascarosides and respond to interspecific dispersal signals.

Ascarosides are a modular series of signalling molecules that are widely conserved in nematodes where they function as pheromones with both behavioural and developmental effects. Here we show that the developmentally arrested infective juvenile (IJ) stage of entomopathogenic nematodes (EPN) secrete ascarosides into the surrounding medium. The exometabolome of Steinernema carpocapsae and Heterorhabditis megidis was examined at 0, 1, 7 and 21 days of storage. The concentration of several ascarosides (ascr#11, ascr#9, ascr#12, ascr#1 and ascr#14 for both species, plus ascr#10 for H. megidis) showed a progressive increase over this period, while the concentration of longer chain ascarosides increased up to day 7, with an apparent decline thereafter. Ascr #9 was the main ascaroside produced by both species. Similar ascarosides were found over a 7-day period for Steinernema longicaudum and S. feltiae. Ascaroside blends have previously been shown to promote nematode dispersal. S. carpocapsae and H. megidis IJs were stored for up to 12 weeks and assayed at intervals. IJs where exometabolome was allowed to accumulate showed higher dispersal rates than those where water was changed frequently, indicating that IJ exometabolome maintained high dispersal. Infectivity was not affected. IJ exometabolome accumulated over 7 days promoted dispersal of freshly harvested IJs, both of their own and other EPN species. Similarly, extracts of nematode-infected cadavers promoted dispersal of con- and heterospecific IJs. Thus, IJs are encouraged to disperse from a source cadaver or from other crowded conditions by public information cues, a finding that may have application in enhancing biocontrol. However, the complexity of the ascaroside blend produced by IJs suggests that it may have ecological functions other than dispersal.

Issues of diagnosis and care for the transgender patient: is the DSM-5 on point?

Issues Ment Health Nurs 2012 Sep;33(9):583-90

Steward Health Care Carney Hospital, Department of Psychiatry, 2100 Dorchester Avenue, Dorchester, MA 02124, USA.

The experience of individuals who happen to be transgender is one that reflects a complex constellation of powerful influences both within and outside of the health care system in the United States. Profound stigma, prejudice, misunderstanding, and hate for these individuals are just a few examples of the formidable challenges that potently shape their lives. The combination of exposed vulnerabilities in the expression of their true selves, and the often hostile environment where this transformation occurs creates the perfect storm for the onset of serious psychiatric illnesses. Oddly enough, the pathology is often not wrought in the experience of the genuine self but more so in what happens to that self in the context of a violent environment. This article explores these factors in the context of psychiatric diagnosis in the DSM-5.
