Lipids fromPlasmodium vinckei-infected erythrocytes and their susceptibility to oxidative damage

The constituent lipids of plasma and red blood cells (RBC) from mice late in infection with the malarial parasitePlasmodium vinckei were analyzed and compared with those obtained from uninfected animals. On a dry weight basis, the total extractable lipids of RBC increased three-fold during infection, while those of the plasma did not change significantly. In general, changes in individual plasma lipid constituents paralleled those found in RBC of infected mice but were of smaller magnitude. While the increase in the total lipids of parasitized RBC was largely attributable to an increase of more than fourfold in total phospholipids, a significant increase in neutral lipids was also observed. Phosphatidylcholine and phosphatidylethanolamine were the major phospholipids present within RBC, and their total and relative concentrations increased as a result of the infection. A parallel increase occurred in the ratio of unsaturated to saturated fatty acids in the parasitized RBC phospholipids. Infection was also associated with decreases in the relative amount of cholesterol present in RBC and in the ratio of cholesterol to phospholipid. Consistent with this, the fluorescence polarization of 1[4-(trimethylamino)phenyl]-6-phenylhexa-1,3,5-triene within parasitized RBC plasma membranes was decreased in comparison with its value in noninfected RBC, indicating that malarial infection decreases the “order” of membrane lipids. These modifications, in conjunction with the increased levels of vitamin E and malonyldialdehyde reported elsewhere, are important determinants of the susceptibility of the different membrane compartments within infected RBC to peroxidative damage.     

Educational facilities and financial assistance for graduate students in psychology: 1966-67.

This report is similar to previous ones on educational facilities and financial assistance for graduate students in psychology. Institutions with graduate programs in psychology are listed, with information supplied by the respective departments. There is no evaluation of these programs and no implication of approval of them by the American Psychological Association, except those doctoral programs in clinical psychology and in counseling psychology that are indicated by the phrase, "PhD in clinical and counseling APA-approved."

1. Contemporary Personnel Psychology.

Introduces the upcoming articles in the first section of the journal, which will in part address the response of industrial/organizational psychologists to the new social issues raised by the Equal Employment Opportunity Commission (EEOC) guidelines and the demands for fair treatment by female applicants and various minorities. The editors highlight the core arguments put forth by each of the contributing authors' articles. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Educational facilities and financial assistance for graduate students in psychology: 1962-63.

Varying degrees of information are given about application requirements, requirements for admission, tuition, types of assistantships, stipends, Veterans Administration traineeships, National Defense Education Act fellowships, United States Public Health Service stipends, etc., for each of 184 institutions.

The APA visiting scientist and international scientist programs: 1963-1964.

"The 1963-64 academic year was the 4th yr. of the Visiting Scientist Program supported by the NSF." Junior colleges with over 500 students were invited to participate; 72 visits were completed by psychologists. The colleges and visitors are listed in a table. Staffs responded warmly and enthusiastically to the visitors. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

3. Understanding Organizational Behavior.

Introduces the articles in this section, which relate primarily to what is labeled as organizational behavior or organizational diagnosis, as distinguished from organizational change and development. The editors asked the authors in this section to address several questions: What basic principles of psychology can be detected in the functioning of organizations? How does the observer modify the organization? (Is it possible to observe and diagnose an organization without modifying it?) What is the significance of the labor as a component of any effort to develop a diagnosis of any industrial enterprise? In addition, an article by Richard Walton has been included on the quality of work life movement, because it represents a linkage between the processes of observation, taxonomy, and categorization and the processes of intervention, change, and development.

Subgroups among opiate addicts: A typological investigation.

Applied a multivariate correlational clustering technique to the MMPI profiles of 1,500 addicts, subdivided into 10 subsamples (5 for each sex) representing 4 different categories of admission into treatment (civilly committed, volunteers, probationers, prisoners). Within each subsample, 2 homogeneous and replicable profile types were isolated. Type I (33% of all Ss) showed elevations on Scales 2, 4, and 8, suggesting marked subjective distress, nonconformity, and disturbed thinking. The much smaller Type II (about 7% of Ss) showed a single peak on Scale 4. 60% of Ss thus were unclustered. The 2 basic types, however, were effectively discriminated on a variety of other psychometric indices and were consistent with the 2 major profile types found among alcoholics in prior research.

Volunteering and the recall of interrupted tasks.

It was hypothesized that the proportion of interrupted tasks recalled would be greatest among volunteers serving by choice and least among draftees not willing to volunteer, with draftees who had been willing to volunteer falling between the 2. Within each of these 3 groups those given task orienting instructions were expected to recall greater proportions of interrupted tasks than those given ego orienting instructions. College students divided into 6 groups of 16 Ss each in a 3 X 2 factorial design were tested individually using the standard Zeigarnik procedure. The results conformed to expectations although the differences among the volunteering groups were small. It was argued that differences in degree of task involvement and ego involvement account for these results. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
