A rule for the early detection of chronic changes in cystic fibrosis patient status.

A statistical decision-making system has been developed which will predict the clinical status of a patient with cystic fibrosis based on daily self measurements obtained at home. The data for the study were collected from CF patients within 7-12 years of age. Thirty-two participants recorded four daily measurements (weight, vital capacity, breathing rate, and resting pulse) and one weekly measurement (height).

The successful allotransplantation of neonatal rat islets across multiple combined major and minor histocompatibility barriers.

Cultured neonatal rat islets were transplanted across six strain combinations into nonimmunosuppressed allogeneic recipients. Islets were isolated nonenzymatically by an in vitro method and were cultured at 37 degrees C in 5% CO2 in air for 10 days prior to transplant. Transplants to nondiabetic recipients across four allogeneic barriers resulted in morphologically intact and well-granulated islet tissue present at the graft site in 54 of 55 cases for periods lasting as long as 445 days (mean day of sacrifice was 163).

Geographic patterns in the flight ability of a monophagous beetle.

The migratory ability of a monophagous insect, Tetraopes tetraophthalmus (Coleoptera: Cerambycidae), was measured in ten populations in each of two regional types. In the first region, a river valley, populations were abundant and close together; in the second regional type, mountainous and peripheral areas, populations were uncommon and far apart. The data revealed that regional variation in migratory behavior occurred along two dimensions.

Impression Management Effects in the Forced Compliance Situation.

Two forced compliance studies were conducted in which the S's expectations regarding the situational appropriateness of his behavior were manipulated. In the first study (N = 36 female undergraduates) E indicated agreement or disagreement with the S's counterattitudinal essay or else did not give an opinion. Although attitude change occurred in the Agree and No Feedback groups, there was none in the Disagree condition.

The effect of non-traumatic audible stress on learning of two motor skills.

Ability to learn two motor tasks while exposed to a continuous 1000-Hz tone of 105 db was compared with learning the tasks without noise. While wearing earphones, half of 40 subjects learned the stabilometer task while the noise was presented and learned the ring-peg task with no noise. The other half had the reverse procedure.
