13. Análise retrospectiva das alterações da dinâmica facial após aplicações seriadas de toxina botulínica tipo A / Retrospective analysis of facial dynamic alterations after multiple botulinum toxin A applications
INTRODUÇÃO: A presença de rugas na face devido à hipercinese muscular é comum nas regiões frontal, glabelar e peri-orbitárias. São descritos diversos métodos para o tratamento das rugas de expressão, como a dermoabrasão, a ablação a laser, o laser não ablativo, preenchimentos, cirurgia e aplicações de toxina botulínica. O tratamento das ruga

14. âNovasâ identidades, limites e fronteiras do rejuvenescimento : equivalÃncias entre idade, jovialidade e maturidade no curso da vida
Esta tese tem por objetivo explorar os limites e fronteiras de identidades, que interferem na constituiÃÃo dos sentidos e dos valores dos lugares sociais que ocupam no momento em que se constituem. Busca processos de diferenciaÃÃo e de homogeneizaÃÃo, que produzem os princÃpios de ordenaÃÃo e hierarquias de valores nos espaÃos sociais, suas divisÃ

15. Aspectos morfo-tectônicos nos platôs de Portalegre, Martins e Santana/RN
A morpho-structural analysis was performed in the uplifted siliciclastic deposits of the Serra do Martins Formation along the Portalegre, Martins and Santana plateaux, in the southeastern and central regions of Rio Grande do Norte State. Due to the lack of biostratigraphic records, this formation has a disputable age.The adopted approach was based on the ana

16. Model Approach to Immunological Rejuvenation of the Aged
Reconstitution of a damaged or exhausted immune system by injection of genetically compatible immunocompetent cells (immunologic rejuvenation) is a promising approach for restoration of immune activity. By using this model, spleen cells from young-adult mice, previously immunized with Salmonella typhimurium, were transferred to either young-adult or old, syn

18. Freezing and rejuvenation of human O erythrocytes for use in the immune adherence hemagglutination test.
A method was established to freeze selected human O erythrocytes and to thaw them as necessary for use in the immune adherence hemagglutination test. This method ensured interrun reproducibility and eliminated the necessity to screen blood donors (fresh cells) for acceptable C3b receptor site sensitivity.

19. Phase identity of the maize leaf is determined after leaf initiation
The vegetative development of the maize shoot can be divided into juvenile and adult phases based on the types of leaves produced at different times in shoot development. Models for the regulation of phase change make explicit predictions about when the identity of these types of leaves is determined. To test these models, we examined the timing of leaf type

20. Therapeutic cloning in the mouse
Nuclear transfer technology can be applied to produce autologous differentiated cells for therapeutic purposes, a concept termed therapeutic cloning. Countless articles have been published on the ethics and politics of human therapeutic cloning, reflecting the high expectations from this new opportunity for rejuvenation of the aging or diseased body. Yet the

21. Minimal Requirements for Commitment to Sporulation in Bacillus megaterium
Commitment to sporulation was examined by means of both endotrophic sporulation and rejuvenation experiments. In both cases, a point of commitment to the completion of sporulation occurred at stage II. With 2 × 108 cells/ml, the process by which commitment occurred required 0.5 mm Mg2+, 10.0 mm phosphate, and an energy source (minimum of 5.0 mm acetate). Fo

22. Response of Leaf Ontogeny and Photosynthetic Activity to Reproductive Growth in Cotton
This study was conducted to determine if reproductive growth in cotton (Gossypium hirsutum L.) affects concurrent leaf development. Apparent photosynthesis (AP), stomatal conductance (Cs), soluble protein (SP), ribulose bisphosphate carboxylase (RuBisCO), and chlorophyll (Chl) were monitored in four main-stem cotton leaves which emerged at approximately 2 we

23. The early phase change Gene in Maize
Recessive mutations of the early phase change (epc) gene in maize affect several aspects of plant development. These mutations were identified initially because of their striking effect on vegetative phase change. In certain genetic backgrounds, epc mutations reduce the duration of the juvenile vegetative phase of development and cause early flowering, but t

24. Immortalization-susceptible elements and their binding factors mediate rejuvenation of regulation of the type I collagenase gene in simian virus 40 large T antigen-transformed immortal human fibroblasts.
Dramatic changes occur in expression of the type I collagenase gene during the process of immortalization in simian virus 40 large T antigen-transformed human fibroblasts (S. Imai and T. Takano, Biochem. Biophys. Res. Commun. 189:148-153, 1992). From transient transfection assays, it was determined that these changes involved the functions of two immortaliza
