Timing of Early-Life Stress and the Development of Brain-Related Capacities.

Early-life stress (ELS) poses risks for developmental and mental health problems throughout the lifespan. More research is needed regarding how specific ELS experiences influence specific aspects of neurodevelopment. We examined the association between ELS, defined as severe adversity (e.

Beyond the ACE score: Examining relationships between timing of developmental adversity, relational health and developmental outcomes in children.

Background: The association between developmental adversity and children's functioning is complex, particularly given the multifaceted nature of adverse experiences. The association between the timing of experience and outcomes is underresearched and clinically under-appreciated. We examine how the timing of both adverse (including potentially traumatic) events and relational poverty are associated with developmental outcomes.

Do sleep problems mediate the link between adverse childhood experiences and delinquency in preadolescent children in foster care?

Background: Adverse childhood experiences (ACEs) are associated with multiple mental and physical health problems. Yet, mechanisms by which ACEs confer risk for specific problems are largely unknown. Children in foster care typically have multiple ACEs and high rates of negative sequelae, including delinquent behaviors.

Bipolar and monopolar radiofrequency treatment of osteoarthritic knee articular cartilage: acute and temporal effects on cartilage compressive stiffness, permeability, cell synthesis, and extracellular matrix composition.

The cellular, biochemical, biomechanical, and histologic effects of radiofrequency-generated heat on osteoarthritic cartilage were assessed. Articular cartilage explants (n=240) from 26 patients undergoing total knee arthroplasty were divided based on Outerbridge grade (I or II/III) and randomly assigned to receive no treatment (controls) or monopolar or bipolar radiofrequency at 15 or 30 W. Both potentially beneficial and harmful effects of radiofrequency treatment of articular cartilage were noted.

Hepatitis delta virus infection in Bombay.

From June 1985 to June 1989, sera from 425 cases of acute viral hepatitis were gathered from 2 hospitals in Bombay; 331 sera were positive for hepatitis B surface antigen and immunoglobulin M anti-hepatitis B core antigen, and the donors' disease was diagnosed as hepatitis B. Anti-hepatitis D virus was found in 124 of these sera, and hepatitis D antigen was present in 24 more, conclusively proving the presence of hepatitis delta infection in association with hepatitis B in Bombay. Among the 425 cases of hepatitis, 39 cases of fulminant hepatitis developed, of whom 31 died.
