Transformation-induced alterations in adhesion. Binding of pre-formed cell aggregates to cell layers

Male and female college students were shown videotapes of supposed male offenders describing the details of thefts they had committed. Videotaped sequences were varied so that offenders were 9 to 10 years old or of college age. Also, actors varied in their mode of emotional self-presentation. Comparisons of punishments suggested by subjects indicated that joyful actors received the highest level of punishment while distressed offenders received the lowest level of suggested punishment. It was also found that the emotions of children exerted a greater persuasive effect on subjects' ratings than did the emotions of adults although the pattern of results was similar across ages. These results were discussed as demonstrating that the age and emotion of an offender can exert considerable influence on the attribution of blame made by a disciplinarian.     

Carcinoma of the cervical stump

A study was made of 56 patients with carcinoma of thecervical stump after subtotal hysterectomy who were seen between 1946 and 1972 at the National Women's Hospital, Auckland, New Zealand. The duration of symptoms before diagnosis, stage distribution and five-year survival rates were examined and compared with those in 1459 patients with carcinoma of the cervix, and no previous subtotal hysterectomy, who presented over the same period.     

The Bjork aortic prosthesis. Study of phonomechanographic parameters, and comparison with the Starr aortic prosthesis

The presence of a cardiodepressant factor of pancreatic origin has been reported in the plasma of experimental animals and man in a variety of shock states. It has been suggested that the depression of developed tension of the isolated cat papillary muscle may be caused by excess NaCl in the bathing medium rather than a specific cardiodepressant peptide. Incubated pancreatic homogenate was used as a source of this factor, and after protein precipitation, ultrafiltration (10,00 and 1,000 MW), dialysis and lyophilization, the residue was applied to a Sephadex G-10 column in order to ensure the removal of all salts. The protein effluent of the Sephadex column contained all the cardiodepressant activity of the filtered, dialyzed pancreatic homogenate and none of the salt content. To further isolate this cardiodepressant factor, the active residue was applied to a cellulose column and eluted with butanol: glacial acetic acid: water (25:26 v/v/v). This elution gave 8 distinct peptide peaks, one of which, peak 4, contained significant depressant activity. Thus, a cardiodepressant peptide of approximately 250-1,000 MW exists in pancreatic homogenates and this compound is not excess NaCl in the assay system.
