Lateral preferences in food reaching and whole-body turning were assessed in 24 prosimian primates: 16 galagos (Galago moholi) and 8 mouse lemurs (Microcebus murinus). Reach and turn preference in the galago were examined using a single testing procedure; separate procedures were used to evaluate reach and turn preferences in the mouse lemur. The motoric requirements for both species were 1) reach into a Plexiglas container with a single hand for a food item and 2) execution of a whole-body rotation about the long axis of the body. Twenty-three of the subjects tested had a reach preference (15 right, 8 left preferent) and 22 a turn preference (1 right and 21 left preferent). No correlation between the direction of reach and turn preference was found for either species; however an association between right reach preference and female gender was found for the galagos. A species difference in the strength of lateralization was found, with the more bipedal species, the galago, more strongly lateralized in both measures. This result supports the hypothesis that the assumption of upright posture was an important factor in the phylogenetic development of primate lateralization. 相似文献

Oudneya africana R. Br. (Brassicaceae), a wild‐growing plant in the arid region of Tunisia, is used in ethno‐medicinal treatment of microbial infections. Validation of ethno‐therapeutic claims pertaining to the plant was sought by investigating its antimicrobial activity. A proteinaceous extract of the seeds, called AS‐3000, showed activity against various organisms including L. monocytogenes, E. coli, B. subtilis, E. hirae, P. aeruginosa, S. aureus and C. albicans. Extract AS‐3000 exhibited a synergistic effect against L. ivanovii when combined with vancomycin or chloramphenicol. The post‐antibiotic inhibitory effect of the ampicillin/AS‐3000 combination was 2.3‐fold greater than for the antibiotic alone. The mode of action of AS‐3000 on Listeria and Escherichia was visible using SEM. These results support the use of O. africana for treating microbial infections. 相似文献

At 6 months the 12 superobese children on protein-sparing modified fast diet had a significant weight loss from baseline (-5.6 ± 7.1 kg, ANOVA p < 0.02); a significant decrease in percentage IBW (-24.3 ± 20%, ANOVA p < 0.002); and had positive growth velocity Z-score (1.3 ± 1.6, ANOVA p < 0.05). Six children were not superobese at 6 months. At 6 months eight of 12 children were active participants and 11 of 12 children were followed. Decrease in blood pressure, as well as, downward trends in serum lipids were observed at 6 months. No clinical complications were observed. At 6 months, the 7 control superobese children, when compared with baseline had gained weight (2.8 ± 3.1 kg, ANOVA p < 0.008); but had no significant change in percentage IBW (-0.3 ± 5.9%, ANOVA p = 0.61); and had no changes in growth velocity Z-score (0.1 ± 1.3, ANOVA p = 0.83). These children did not have any change in blood pressure and an upward trend in serum lipids were observed at 6 months. Protein-sparing modified fast diet and a hypocaloric balanced diet appear to be effective in a group of superobese-school-age children in a medically supervised clinic-based program implemented in a school setting over a 6-month period. The efforts of committed clinic staffs, school officials, peers, and family involvement were crucial to the success of this intervention program in promoting and maintaining weight loss over a 6-month period. Further research with a specific comparison of the hypocaloric diets with longer follow-up periods in the school setting is necessary. In the meantime, these diets should be used only with close medical supervision. 相似文献

Undernourished mother rats were given daily meals throughout most or all of pregnancy and lactation, comprising about half the amount of a good quality diet taken by controls. Their daily pattern of nest occupation and desertion during lactation was quite different from that of controls. Retrieving tests were carried out at 4, 6, 8 and 10 days after parturition. Underfed mothers were less efficient than controls in retrieving their young on days 8 and 10, and were less likely to lick their young during the test period. They also spent much more time rearing on their hind legs. Among undernourished females the number of young retrieved was negatively correlated with duration of rearing. The significance of the differences in maternal behaviour for offspring development is discussed. 相似文献

Background
The exponential growth of research in molecular biology has brought concomitant proliferation of databases for stocking its findings. A variety of protein sequence databases exist. While all of these strive for completeness, the range of user interests is often beyond their scope. Large databases covering a broad range of domains tend to offer less detailed information than smaller, more specialized resources, often creating a need to combine data from many sources in order to obtain a complete picture. Scientific researchers are continually developing new specific databases to enhance their understanding of biological processes. 相似文献466.
