An assay for ataxia-telangiectasia (A-T) heterozygotes, i.e., healthy carriers of the A-T gene(s), requiring only a small sample (3.5 mL) of peripheral blood, is described. Frequencies of chromatid aberrations in phytohemagglutinin-stimulated blood lymphocytes collected by demecolcine from 0.5 hour to 1.5 hours after x irradiation with 58 roentgens were(More)
Six Raynaud's disease and four Raynaud's phenomenon patients were treated with 12 sessions of finger temperature biofeedback. The mean frequency of vasospastic attacks was reduced to 7.5% of that reported during the pretreatment baseline and was maintained for a 1 year follow-up period. Significant control of digital temperature was demonstrated during(More)
The unrestricted adult social and nonsocial behavior of albino rats isolated from 21 to 70 days of age was compared with the behavior of rats receiving normal social experience. Isolated animals exhibited aberrant self-manipulative behaviors during the period of isolation, and both isolate-reared males and females were more aggressive than their(More)
Antibody-dependent, cell-mediated cytotoxicity in the Moloney sarcoma virus (MSV) system was analyzed in terms of the ability of autochthonous antibody to induce or potentiate cytotoxicity by lymphocytes from animals infected with MSV. As previously demonstrated in microcytotoxicity assays, the lymphocytes from regressor animals taken 30 days after virus(More)
Adult T-cell leukemia (ATL) is a malignancy of mature lymphocytes caused by the retrovirus human T-cell lymphotrophic virus-I (HTLV-I). It is an aggressive leukemia with an overall mortality rate of 50% within 5 months; no conventional chemotherapy regimen appears successful in inducing long-term disease-free survival in ATL patients. However, ATL cells(More)
Seahorses populations in the wild have been declining and to restore them a better knowledge of seahorse reproduction is required. This study examines the effect of dietary quality on seahorse fecundity and egg quality. Two different diets were tested with Hippocampus kuda females: frozen mysis (control) and frozen mysis enriched with a liposome spray(More)
Forty-five pregnancies in rhesus monkeys maintained in a semioutdoor environment and fed about 1, 2, or 4 g of protein/kilogram of body weight each day in otherwise equivalent diets were observed. The 4-g diet shortened gestation 8.5 days. Male infants were carried 6 days longer than females; part of difference can be attributed to their greater(More)
