The Psychopathic Personality Inventory (PPI-Revised) is a personality test for traits associated with psychopathy in adults. The PPI was developed by Scott Lilienfeld and Brian Andrews to assess these traits in non-criminal (e.g. university students) populations, though it is still used in clinical (e.g. incarcerated) populations as well.
Prepulse inhibition (PPI) is a neurological phenomenon in which a weaker prestimulus (prepulse) inhibits the reaction of an organism to a subsequent strong reflex-eliciting stimulus (pulse), often using the startle reflex.
Cover of Hare's Psychopathy Checklist-Revised (2nd ed., 2003). The Psychopathy Checklist or Hare Psychopathy Checklist-Revised, now the Psychopathy Checklist—revised (PCL-R), is a psychological assessment tool that is commonly used to assess the presence and extent of psychopathy in individuals—most often those institutionalized in the criminal justice system—and to differentiate those ...
The test-retest reliability for over 6 years, as reported in the NEO PI-R manual, was the following: N = .83, E = .82, O = .83, A = .63, C = .79. Costa and McCrae pointed out that these findings not only demonstrate good reliability of the domain scores, but also their stability (among individuals over the age of 30).

In this case, a modeling strategy named generalized PPI was proposed. [6] Traditionally, the PPI analysis was implemented using a seed-based strategy. That is, the PPI term is defined using a pre-defined seed, and a voxel-wise analysis is performed to identify regions in the whole brain that showed task modulated connectivity with the seed region.
Impedance–pH monitoring is a technique used in the diagnosis of gastroesophageal reflux disease (GERD), by monitoring both impedance and pH. [1] [2]Patients with ongoing symptoms while on proton-pump inhibitor (PPI) therapy are commonly diagnosed with impedance–pH monitoring while continuing their medications.
Specifically, PPI use was associated with reduced lumbar spine trabecular bone score (TBS), as well as lower bone mineral density (BMD) T-scores in the lumbar spine, total hip, and femoral neck. [41] These findings suggest that long-term PPI use may negatively affect bone health in men.
