A neural mechanism for discriminating social threat from social safety.

The ability to distinguish a threatening from non-threatening conspecific based on past experience is critical for adaptive social behaviors. Although recent progress has been made in identifying the neural circuits that contribute to different types of positive and negative social interactions, the neural mechanisms that enable the discrimination of individuals based on past aversive experiences remain unknown. Here, we developed a modified social fear conditioning paradigm that induced in both sexes robust behavioral discrimination of a conspecific associated with a footshock (CS+) from a non-reinforced interaction partner (CS-).

Development of a clinic for adults with Down syndrome.

In an effort to better support the adults with Down syndrome that it serves, parents from the National Association for Down Syndrome, a parent organization, worked with staff members from The Family Study and Service Program of the University Affiliated Program for Developmental Disabilities of the University of Illinois and the Department of Family Practice of Lutheran General Hospital to develop a clinic for adults with Down syndrome. The clinic was developed to provide comprehensive health care with an emphasis on preventative services. The multidisciplinary approach of the clinic has proved to be effective in the management of a variety of patient care needs.

[Fibrinolytic activity in traumatic hemothorax fluids].

Twenty-nine patients, 15 to 85-year-old (mean: 50 years) who presented with a pleural effusion after trauma were studied. The blood content of pleural fluid was confirmed by thoracocentesis. None of the patients had been taking anticoagulant drugs during the fortnight preceding the trauma.
