Public figures on trial: an assessment of the use of the "jury court" technique for city officials in Santa Catarina, Brazil

This study describes the 'Law Court' technique as applied to City Health Departments in the State of Santa Catarina, in dealing with the issue of obligations on the part of public officials. The project was the first part of a training course for public administrators held in 1997. The article presents the technique's components and results. Some 98% of the 156 participants had a positive opinion of the training course, considering it dynamic/participatory (31%), educational/stimulating reflection (27%), and realistic (24%). The technique fostered the discussion of the main subjects pertaining to the country's Unified Health System (SUS). Although all five juries acquitted the defendants, the issue of ethics was reported by 58% of the participants as the main prerequisite for a public administrator.     

The impact of a family planning multimedia campaign in Bamako, Mali

An integrated multimedia campaign featuring family planning messages saturated the 900,000-person city of Bamako, Mali, for three months during the spring of 1993. With traditional theater and music, family planning messages were repeatedly broadcast on radio and television that conveyed information about modern contraceptive methods, the need for male sexual responsibility, the health and economic advantages of family planning, the need for communication between spouses, and that Islam, the predominant faith of Mali, does not oppose family planning. A separate sample pretest-post-test quasi-experimental research design was used to evaluate the effects of the campaign and exposure to specific messages on changes in contraceptive knowledge, attitudes, and practice. Results indicate a high level of exposure to and agreement with the messages. A dramatic drop was found in the proportion of men and women who believe that Islam opposes family planning. Logistic regression results indicate that contraceptive knowledge and use and more favorable attitudes toward family planning are positively associated with intensity of exposure to the project interventions, after controlling for relevant variables.

Relationship of the meniscofemoral ligaments of the knee to lateral meniscus tears: magnetic resonance imaging evaluation

This study sought to determine if the presence or absence of meniscofemoral ligaments exerts an influence on the prevalence of tears of the lateral meniscus. We reviewed the sagittal and coronal magnetic resonance images of 173 knees for lateral meniscus tears and the presence of the meniscofemoral ligaments. One or both meniscofemoral ligaments were present in 142 of 173 knees (82%). Fifty-four knees had lateral meniscus tears, 27 of which involved the posterior horn. Thirty-three percent of knees with meniscofemoral ligaments had a lateral meniscus tear, and 23% of knees without meniscofemoral ligaments had a lateral meniscus tear (no significant difference). We found no association between the presence of the meniscofemoral ligaments and tears of the lateral meniscus. Our study questions the importance of preserving or reconstructing these ligaments in instances of meniscal transplantation.     

Postpartum hemorrhage of the uterine artery rupture

Fatty masses, especially solid lipomas, in the paediatric abdomen are very rare. We present such a case, that of an 11-year-old boy who was admitted with abdominal pain and distension. The pre-operative diagnosis of lipoma was suggested by US and CT. The diagnosis of simple lipoma arising in the leaves of the small bowel mesentery, without immature cells, was verified microscopically after the operation. The tumour was enucleated from the mesenterium leaving the intestine intact. We underline the importance of US and CT as pre-operative diagnostic tools.     

Exit from mitosis in Drosophila syncytial embryos requires proteolysis and cyclin degradation, and is associated with localized dephosphorylation

The cyclin proteolysis that accompanies the exit from mitosis in diverse systems appears to be essential for restoration of interphase. The early syncytial divisions of Drosophila embryos, however, occur without detectable oscillations in the total cyclin level or Cdk1 activity. Nonetheless, we found that injection of an established inhibitor of cyclin proteolysis, a cyclin B amino-terminal peptide, prevents exit from mitosis in syncytial embryos. Similarly, injection of a version of Drosophila cyclin B that is refractory to proteolysis results in mitotic arrest. We infer that proteolysis of cyclins is required for exit from syncytial mitoses. This inference can be reconciled with the failure to observe oscillations in total cyclin levels if only a small pool of cyclins is destroyed in each cycle. We find that antibody detection of histone H3 phosphorylation (PH3) acts as a reporter for Cdk1 activity. A gradient of PH3 along anaphase chromosomes suggests local Cdk1 inactivation near the spindle poles in syncytial embryos. This pattern of Cdk1 inactivation would be consistent with local cyclin destruction at centrosomes or kinetochores. The local loss of PH3 during anaphase is specific to the syncytial divisions and is not observed after cellularization. We suggest that exit from mitosis in syncytial cycles is modified to allow nuclear autonomy within a common cytoplasm.     

Alzheimer's peptides A beta 1-40 and A beta 1-28 inhibit the plasma cholesterol esterification rate

The amyloid fibrils of Alzheimer's disease and Down's syndrome amyloid deposits are composed mainly of aggregated amyloid beta protein (A beta) which also exists in a soluble form. It has been shown that both Alzheimer's disease and Down's syndrome share another common feature: the decrease in plasma cholesterol esterification in affected individuals. In the present work the effect of synthetic peptides A beta 1-40 and A beta 1-28 on normal human plasma cholesterol esterification rate was studied. Both peptides at a concentration of 1 ng/ml inhibited plasma cholesterol esterification rate to 40-50 % of control value. Statistical analysis showed no differences in the effect of A beta 1-40 and A beta 1-28 on the inhibition, suggesting the importance of A beta sequence 1-28 for this effect.     

Primary electron donors for Azotobacter chroococcum nitrogenase

Augmentation mammaplasty by the transaxillary approach seems to be a safe and anatomically sound procedure which produces consistent results with a low complication rate. Our experiences with this procedure and our modifications in the technique are described. Two instruments which were designed to facilitate the procedure are reported. An anatomical justification for the transaxillary method is made.
