Cardiac Vagal Tone, defensiveness, and motivational style.

Cardiac Vagal Tone has been proposed as a stable biological marker for the ability to sustain attention and regulate emotion [Porges, Monographs of the Society for Research in Child Development 59 (1994) 167-186]. Vagal tone is a physiological index of parasympathetic nervous system influence on the heart that has predicted a number of emotional behaviors and styles in infants, children, and adults. Little research, however, has sought to explore the link between vagal tone and established variables relating to personality and self-regulation.

The objective assessment of amnesia in dissociative identity disorder using event-related potentials.

Assessment of amnesia in Dissociative Identity Disorder (DID) typically relies on self-report, the veracity of which cannot often be independently verified. Memory in DID was therefore assessed using an objective method that involved event-related potentials (ERPs) as well as indirect behavioral measures of memory, and that provided statistically supported assessments for each participant. Four participants who met DSM-IV criteria for DID participated in an ERP memory assessment task, in which words learned by one identity (identity A) were then presented to a second identity (identity B).

Prolene sutures are not a significant factor in anastomotic false aneurysms.

Anastomotic false aneurysms have been a significant complication in vascular surgery, and the sutures used have been a major cause. Monofilament sutures have been indicated as contributing to the formation of false aneurysm. However, most of the monofilament sutures operative in the formation of false aneurysms have been made of polyethylene.
