The aim of the research project was to find out the conditions of a successful occupational qualification of older workers in the Federal Republic of Germany. The more recent results of psychological research concerning the learning capacities of older people suppose that older workers can also be qualified successfully with regard to the requirements of their job. However, the project results reveal that certain basic conditions should be fulfilled for the qualification of older workers.

To prevent graft-versus-host disease, T lymphocytes were removed from the grafts by agglutination with soybean agglutinin and rosette formation with sheep red blood cells. None of the patients received conditioning treatment before transplantation.

Mycelial levels of ATP and glucose-6-phosphate were investigated in mutants of streptothricin-producing S. noursei JA 3880b differing from the wild-type strain in antibiotic formation, in the control by inorganic phosphate of the secondary metabolism, and in the resistance to growth inhibition by toxic arsenate ions. As compared with the ancestral strain, mutants exhibited a lower content of ATP in the mycelium while addition of 0.

Whereas in the AsR-strains obtained from both wild type and mutant NG 13 the antibiotic production was reduced to approx. 60% of the parental level, the AsR clones isolated from colony populations of mutant UV 12 displayed increased productivity (less than or equal to 150%).

Of the 122 preovulatory oocytes which were recovered from these patients, 44 (36%) were fertilized and cleaved, and were transferred. 144 immature oocytes were collected, and attempts were made to mature these in vitro.

Contrary to previous reports, our study shows that not all SCID patients lack NK activity; some may even express very high NK- and antibody-dependent cellular cytotoxicity (ADCC). The present group of eight SCID infants was homogeneous with respect to normal levels of the purine metabolism enzymes adenosine deaminase (ADA) and purine nucleoside phosphorylase (PNP).

This inconsistency is partly due to methodological inadequacies and a narrow focus on unidimensional variables with unimodal measurements. In addition, no succinct model has been presented to explain family adaptation and the range of possible outcomes.

This leads to a reduction of the calculated radiation exposure in the environment by more than a factor of ten with regard to pure elemental iodine releases.

The Questionnaire on Resources and Stress (QRS, Holroyd, 1974) was designed to answer this need, but the length and psychometric weaknesses of this instrument have interfered with more widespread usage. In the present investigation, data from 289 QRSs were item analyzed, and 52 items emerged as most reliable, forming a short form of the QRS.

The present study was aimed at investigating recovery of humoral immunity in vitro after bone marrow transplantation in patients with acute leukemia and severe aplastic anemia. Hemolytic plaque assays were utilized to quantitate pokeweed mitogen-stimulated polyclonal immunoglobulin production and sheep erythrocyte antigen-specific antibody responses in cultures of peripheral blood mononuclear cells of 39 patients beginning at 1 month, for variable periods up to a maximum of 4 years after marrow transplantation. Three phases were identified: an early period of primary B cell dysfunction with concomitant immunoregulatory T cell abnormalities--i.

In no single case was a false result obtained from the two former methods, when used together. Hence, chromosomal analysis proved to be necessary only in something between five and eight per cent of all examinations.

Results were separately evaluated for patients in normal gonadotrophic conditions, on the one hand, and those in hypogonadotrophic conditions, on the other. They were compared with findings obtained from other groups between which no distinction had been possible due to the use of earlier methods for gonadotrophin determination.
