1. Biologia de osteoclastos: estudo in vivo dos aspectos estruturais de osteoclastos sob a ação do estrógeno e estudo in vitro da osteoclastogênese a partir de precursores de sítios ósseos distintos. / Osteoclast biology: in vivo study of the estrogen action on osteoclasts and in vitro study of the osteoclastogenesis from precursors of distinct bone sites
Introduction: Bone is a mineralized tissue that is under the influence of several systemic, local and environmental factors. Among systemic factors, estrogen is a hormone well known for its inhibitory function on bone resorption. As alveolar bone of young rats undergoes continuous and intense remodeling to accommodate the growing and erupting tooth, it is a

2. A IMPORTÃNCIA DA ROTULAGEM AMBIENTAL PARA O DESENVOLVIMENTO SUSTENTÃVEL: UM ESTUDO DE CASO PARA OS PRODUTOS ORGÃNICOS NA CIDADE DE FORTALEZA / MATTERS OF ENVIRONMENTAL LABELING FOR SUSTAINABLE DEVELOPMENT: A CASE STUDY FOR ORGANICS PRODUCTS IN FORTALEZA CITY.
This study was developed around the issues related to consumption of agricultural products of organic origin and the process of labeling of these products in order that sought to examine whether this form of consumer goods are conscious enough to give preference to consumption of products labeled organic, considering the positive impact of their production t

3. Segurança alimentar e princípio da informação sobre alimentos geneticamente modificados : perspectivas jurídica e socioambiental
Os panoramas social e ambiental estão intimamente relacionados, o que atrai a perspectiva socioambiental. Assim, as interferências nas condições de vida da população proporcionadas pela biotecnologia são compreendidas na proteção ao meio ambiente. A comercialização de organismos geneticamente modificados em alimentos gera muito debate doutrinário

4. Avaliação dos efeitos das exigências técnicas nas exportações brasileiras de alimentos / Evaluation on the effects technical requirements produces on Brazilian food products exports
This research analyzes how the effects of the difficulties that food industry faces to adapt to the export technical standards affects its export performance. In addition, it aims to identify which technical requirements most affect the food industry and which characteristics most influence them. The data was collected in a survey with 117 firms and analyzed

5. Cytogenotoxicity of SPL "(Spent Pot Liner" by plant root tip bioassays. / Citogenotoxidade do SPL (Spent Pot Liner) por meio de bioensaios vegetais em Ãpice radicular.
SPL (Spent Pot Liner) is a toxic solid waste generated by aluminum industry during the manufacturing of aluminum metal in electrolytic cells. It has a composition highly variable including fluoride salts, cyanides, metals and organic compounds. In Brazil, aluminum industries generate about 35,000 t of SPL per year. Some industries recycle this waste as feeds

6. Efeitos da exposição crônica à poluição atmosférica particulada sobre o desenvolvimento embrionário pré-implantacional in vitro em camundongos / Effects of chronic exposure to particulate air pollution on in vitro preimplantation embryo development in mice
A thematic research project to evaluate the health effects of acute/chronic exposure to ambient air in a large urban center was developed at the Air Pollution Laboratory in the Department of Pathology at the University of São Paulo School of Medicine. Within this project a specific research line was committed to the study of the effects of this exposure on

7. Novas tecnologias e percepção de risco: análise das opiniões sobre transgênicos publicadas na imprensa brasileira (2003-2004) / New technologies and risk perception: an analysis of the opinions about transgenics published on the brasilian press (2003-2004)
This dissertation presents an analysis of the opinions texts published about the genetic modified organisms in the newspapers Estado de Minas, Folha de S. Paulo, O Globo and Zero Hora, between 2003 and 2004. The aim was to identify which social or cultural values had been used in the construction of the different risk perceptions that circulated in these pub

8. A influência do conceito de operações estabelecedoras na prática de um analista do comportamento: uma análise de artigos de autoria ou co-autoria de B. A. Iwata publicados no Journal of Applied Behavior Analysis, no período de 1990 a 2005 / The influence of the concept of establishing operations over a Bbhavior analysts practice: a study of B. A. Iwatas articles, published in JABA, between 1990 and 2005
Michael (1982, 1988, 1993, 2000) defines establishing operation as a change in the environment that alters the effectiveness of some object or event as reinforcer and, simultaneously, alters the momentary frequency of the response which have been followed by that reinforcer. According to Michael (1982), the formulation of this new scientific term has more va

9. Catabolism of Tritiated Thymidine by Aquatic Microbial Communities and Incorporation of Tritium into RNA and Protein †
The incorporation of tritiated thymidine by five microbial ecosystems and the distribution of tritium into DNA, RNA, and protein were determined. All microbial assemblages tested exhibited significant labeling of RNA and protein (i.e., nonspecific labeling), as determined by differential acid-base hydrolysis. Nonspecific labeling was greatest in sediment sam

10. Steady-State Photosynthesis in Alfalfa Leaflets: Effects of Carbon Dioxide Concentration 1
When the CO2 concentration to which Medicago sativa L. var. El Unico leaflets were exposed was increased from half-saturation to saturation (doubled rate of photosynthesis), glycolate and glycine production apparently decreased due to inhibition of a portion of the glycolate pathway. Serine and glycerate production was not inhibited. We conclude that serine

11. Selected Nucleic Acid Precursors in Studies of Aquatic Microbial Ecology
The use of radiolabeled nucleosides and nucleic acid bases to estimate the rates of RNA and DNA synthesis in naturally occurring microbial assemblages requires numerous assumptions, several of which are evaluated herein. Comparative time series analyses of the uptake and incorporation, labeling specificity, and extent of catabolism of [2-3H]adenine, [methyl-

12. Apoptosis induced by environmental stresses and amphotericin B in Candida albicans
New antifungal agents are urgently required to combat life-threatening infections caused by opportunistic fungal pathogens like Candida albicans. The manipulation of endogenous fungal programmed cell death responses could provide a basis for future therapies. Here we assess the physiology of death in C. albicans in response to environmental stresses (acetic
