Childhood emotional abuse and neglect as predictors of psychological and physical symptoms in women presenting to a primary care practice.

Objective: There were two aims to this study: first to examine whether emotional abuse and neglect are significant predictors of psychological and somatic symptoms, and lifetime trauma exposure in women presenting to a primary care practice, and second to examine the strength of these relationships after controlling for the effects of other types of childhood abuse and trauma.

Method: Two-hundred and five women completed the Childhood Trauma Questionnaire (Bernstein et al., 1994), Trauma History Questionnaire (Green, 1996), the Symptom Checklist-revised (Derogatis, 1997), and the Revised Civilian Mississippi Scale for posttraumatic stress disorder (Norris & Perilla, 1996) when presenting to their primary care physician for a visit.

Family of shuttle vectors for ruminal Bacteroides.

A family of shuttle plasmids was constructed for genetic transformation of Escherichia coli and of ruminal Bacteroides strains AR20 and AR29. Plasmids were based on the replicon from Bacteroides plasmid pBI191 and were designed for studies of chromosomal integration (pBA), for the identification and study of Bacteroides gene promoters (pPPR) and for the expression of heterologous genes in Bacteroides (pBAC). Electroporation efficiency of Bacteroides was up to 10(5) transformants/microg plasmid, depending on the source of the DNA.

Post-traumatic stress disorder: advances in psychoneuroimmunology.

Exposure to trauma can result in immune dysregulation, and increasing evidence suggests that there are immune alterations associated with post-traumatic stress disorder (PTSD). However, the exact nature of these immune findings in PTSD has not been defined. The study of psychoneuroimmunology in PTSD is relevant not only for understanding the biological underpinnings of this disorder, but also for establishing the nature of the associations between PTSD and other medical and psychiatric illnesses.

The transcriptional regulator gene phrR in Sinorhizobium meliloti WSM419 is regulated by low pH and other stresses.

The phrR gene in Sinorhizobium meliloti (previously known as Rhizobium meliloti) WSM419, directly downstream from actA, is induced by low pH or certain stresses (e.g. high concentrations of Zn2+, Cu2+, H2O2 or ethanol), but not in stationary phase or by other stresses (e.
