posttraumatic stress disorder PTSD; an anxiety disorder caused by exposure to an intensely traumatic event, such as rape or assault, military combat or bombing of civilians, torture, death camps, natural disasters, terrible accidents, developmentally inappropriate sexual experiences, or life-threatening illness. Characteristics include reexperiencing the traumatic event in recurrent intrusive recollections, nightmares, or flashbacks; avoidance of trauma-associated stimuli and a generalized numbing of emotional responsiveness; and hyperalertness with difficulty in sleeping, remembering, or concentrating. The onset of symptoms may be delayed for months to years after the event.

post·trau·mat·ic stress dis·or·der (PTSD),

1. development of characteristic long-term symptoms following a psychologically traumatic event that is generally outside the range of usual human experience; symptoms include persistently reexperiencing the event and attempting to avoid stimuli reminiscent of the trauma, numbed responsiveness to environmental stimuli, a variety of autonomic and cognitive dysfunctions, and dysphoria.
2. a DSM diagnosis that is established when the specified criteria are met.

posttraumatic stress disorder

n. Abbr. PTSD
A psychiatric disorder resulting from a traumatizing experience, such as torture, rape, or military combat, characterized by recurrent flashbacks of the traumatic event, nightmares, persistent negative emotions such as anger, fear, or shame, and difficulty experiencing positive emotions.

a DSM-IV psychiatric disorder characterized by an acute emotional response to a traumatic event or situation involving severe environmental stress, such as a natural disaster, airplane crash, serious automobile accident, military combat, or physical torture.

posttraumatic stress disorder

Psychology A psychologic disorder linked to the mental stress of intense trauma or armed conflict; PTSD is defined as one or more of the following: Sx related to re-experiencing a traumatic event, Sx related to avoiding stimuli associated with the trauma, numbing of general responsiveness, or Sx related to ↑ arousal with long-term psychologic 'scars' Etiology Combat, rape, child abuse, witnessing a violent event, or any serious medical or psychological trauma Clinical Nightmares, inability to concentrate, and intrusive thoughts about the traumatic event, numbing, irritability, guilt–for having survived when others died, recurrent nightmares, flashbacks to traumatic scene, overreactions to loud noises, dissociation, anxiety or panic attacks, depression, or anger; PTSD is associated with ↑ alcoholism and may arise in a background of child abuse, PTSD is similar to the 'Vietnam syndrome'; the 'shell shock' form of PTSD occurs in less than 1% of the general population, 15-35% of Vietnam veterans, 30-50% of those exposed to natural disasters and up to 80% of those exposed to man-made disasters–eg, Bhopal.

This in vivo result is also verified by the in- vitro excretion study, and the PAH secretion rate in the isolated PTSs from exhausted rats remained unchanged.
1999; 2001; 2003a; 2005; Zager and Kalhorn, 2000) did not include heavy muscle activity as a stressor, the results of the present study clearly indicated that, like other stressors, strenuous physical activity renders the kidneys more resistant to subsequent attacks, because the isolated PTSs from exhausted rats showed resistance to ATP depletion and released less LDH into the medium (Figure 2).
Altered PAH entry may be responsible for this imbalance, since the tubular PAH secretory rate remained unchanged in the PTSs of the exhausted rats.
The final academic module of PTSS 08-5 concerned the expanding role of homeland security in the counterterrorism mission.
A highlight of PTSS 08-5 was a weeklong field study to examine the French approach to counterterrorism.
A special operations section of the DGGN known as the Groupe d'Intervention de la Gendarmerie Nationale (National Gendarmerie Intervention Group, or G1GN), an elite counterterrorism and hostage rescue unit, provided kinetic demonstrations for PTSS 08-5, including hostage rescue, diplomatic security, weapons of mass destruction response, and convoy protection.
To get an impression of what happens to a sample during the hand-carried transport or by PTS we used MSR 145W miniaturized (18 x 14 x 62 mm, 18 g) data loggers for measuring and recording temperature, humidity with integrated temperature, pressure, and 3-axis acceleration (MSR Electronics).
The blood parameters measured after transport by hand or by the PTS were analyzed and compared between groups by using a paired and 2-sided Welch f-test.
The average duration of the sample transport via PTS was 5-6.
Going forward in the 21st century, PTSS is committed to partnering with its customers to drive innovation in this rapidly evolving field of data encryption and management.
PTSS has also added a blog for the community to view comments on the latest happenings in the encryption space.
She added that future treatments might occur away from a hospital setting, because people with PTSS may avoid locations such as hospitals that are associated with the cancer experience.
