| [effect of 2-ketogluconic acid synthesis on the exopolysaccharide production in a rhizobium meliloti strain]. | two categories of carbon substrates are defined for rhizobium meliloti: the first favours the synthesis of exopolysaccharides (fructose belongs to this category) while the other is not suitable (glucose belongs to this category). with fructose, resting cells synthesize polysaccharides during more than 100 h and this synthesis is at its best in aerobic conditions at 30 degrees c. with glucose, 2-ketogluconic acid accumulates and rapidly stops the synthesis. the method used to stop this acidificat ... | 1979 | 43767 |
| determinants of the longevity of third-stage infective larvae of ancylostoma tubaeforme. | the effects of some extrinsic factors on the lipid (energy) reserves and longevity of third-stage larvae of the cat hookworm ancylostoma tubaeforme, were investigated under controlled laboratory conditions. in nonstressful microenvironmental conditions, larval longevity was directly related to the rate of utilisation of the lipid reserves. the effects of the various environmental stresses on longevity could also be explained largely on the basis of their deleterious effects on the lipid metaboli ... | 1979 | 44307 |

| demonstration of a thymus derived, splenic suppressor cell responsible for the age-dependent decrease in contact hypersensitivity in the adult mouse. | a suppression of contact hypersensitivity to picryl chloride has been demonstrated in adult thymectomized, 4 and 5 1/2 mo-old cba mice after i.v. injection of spleen cells from intact cba mice of the same age. the cells signifcantly suppressed the elicitation of the allergic contact sensitivity reaction and this effect could be inhibited by pretreating the cells with anti-thy 1 serum and complements. the induction phase was found to be unaffected. however, spleen cells from donors which had rece ... | 1979 | 311798 |

| selective retrieving by maternal and nonmaternal female rats. | an earler study reported that nonpregnant females do not selectively retrieve a pup over a small plastic toy, while lactating mothers retrieve the pup more often than the toy. the present study was undertaken to see whether nonpregnant females made maternal by exposure to pups would act more like nonmaternal females than lactating mothers. the behavior toward a pup and a toy was studied in 1 group of nonmaternal virgins, 2 groups of maternal virgins, and 1 group of lactating mothers, during 7 da ... | 1975 | 1167224 |
| onset of steroidogenesis and differentiation of functional lh receptors in rat fetal testicular cultures. | the present study was performed to investigate in vitro the onset of steroidogenesis and the responsiveness to lh in rat fetal testes. the male gonads explanted on days 12.5, 13.5, and 14.5 of gestation in m199 produced testosterone from 15.5 days as is the case in vivo dcamp (1 mm) induced an anticipated steroidogenesis on day 14.5 with secretions of testosterone (0.026 +/- 0.003 ng/gonad/24 h) and progesterone (0.078 +/- 0.005 ng/gonad/24 h), whereas lh (100 ng/ml) has no effect. antiandrogens ... | 1987 | 2823733 |
| human milk-derived lactoferrin inhibits mitogen and alloantigen induced human lymphocyte proliferation. | purified lactoferrin (lf), isolated from human milk, was tested for its effect on human t-lymphocyte proliferative responses to phytohemagglutinin (pha) and to alloantigens in mixed lymphocyte culture. lf inhibited proliferation in both assays in a dose-dependent manner. the suppressive effect was not due to lf mediated cytotoxicity since washing cells that had been pre-incubated with lf restored their proliferative activity. lf was most effective in suppressing the pha response when added withi ... | 1987 | 2963123 |

| relationships among life stress, perceived family environment, and the psychological distress of spina bifida adolescents. | fifty-three teen-agers with spina bifida participated in a mail survey and completed measures of recent life events, perceived family environment, and psychological distress. low levels of perceived family conflict and control served as life stress buffers in the prediction of distress, whereas a high level of perceived independence served as a life stress exacerbator. these interaction effects differ from those obtained for a normal sample of adolescents in the lone previous study (burt, cohen, ... | 2009 | 2666629 |
