Hard and soft tissue changes around implants installed in regular-sized and reduced alveolar bony ridges. An experimental study in dogs

Objective: To study bony and soft tissue changes at implants installed in alveolar bony ridges of different widths.Material and methods: In 6 Labrador dogs, the mandibular premolars and first molars were extracted, and a buccal defect was created in the left side at the third and fourth premolars by removing the buccal bone and the inter-radicular and interdental septa. Three months after tooth extraction, full-thickness mucoperiosteal flaps were elevated, and implants were installed, two at the reduced (test) and two at the regular-sized ridges (control). Narrow or wide abutments were affixed to the implants. After 3 months, biopsies were harvested, and ground sections prepared for histological evaluation.Results: A higher vertical buccal bony crest resorption was found at the test (1.5 +/- 0.7 mm and 1.0 +/- 0.7 mm) compared to the control implants (1.0 +/- 0.5 mm and 0.7 +/- 0.4 mm), for both wide and narrow abutment sites. A higher horizontal alveolar resorption was identified at the control compared to the test implants. The difference was significant for narrow abutment sites. The peri-implant mucosa was more coronally positioned at the narrow abutment, in the test sites, while for the control sites, the mucosal adaptation was more coronal at the wide abutment sites. These differences, however, did not reach statistical significance.Conclusions: Implants installed in regular-sized alveolar ridges had a higher horizontal, but a lower vertical buccal bony crest resorption compared to implants installed in reduced alveolar ridges. Narrow abutments in reduced ridges as well as wide abutments in regular-sized ridges yielded less soft tissue recession compared to their counterparts.

Estudos estruturais por difração de raios X de fosfolipases A2 em presença de íons com importância funcional

Snakes from Bothrops genus are responsible for more than 90% of the ophidian accidents in Brazil. One of the main complications from this kind of accident is muscular necrosis, which is related to the action of phospholipases A2 and metalloproteases, two groups of enzymes found in the venom of these animals. Although this complication cannot be solved by serum therapy administration, a great number of studies have been performed with the attempt to know the pharmacological sites of these toxins aiming, in the future, the development of complementary treatments to serum therapy. This work proposes structural studies of bothropic phospholipases A2 (PLA2s) in the presence of ions relevant to their activity, using the X-ray crystallography technique. Recently, it was demonstrated ions, as manganese, calcium and others, interfere in the biological activity of the PLA2s. Particularly, Lys49-PLA2s in the presence of manganese ions have miotoxicity reduced. Asp49-PLA2s show catalytic activity dependent of calcium, although structural studies with a miotoxic Asp49-PLA2, BthTX-II, suggest a possible catalytic mechanism independent of calcium. Therefore, co-crystallization of BthTX-II in the presence of calcium ions and of PrTX-I in the presence of manganese ions were performed. Comparative structural studies among obtained results and others already published in the literature were performed aiming a better understanding of the structure-function relationship of these toxins. The BthTX-II with the presence of calcium do not show this ion in the loop of coordination of calcium, presence necessary to develop the catalyses. After comparison of this model with the native one, only one distortion was found, but no apparent relationship with the residues responsible for its activity. In the PrTX-I structure, regions candidates of manganese ions were also found... (Complete abstract click electronic access below)

Gestão de resíduos sólidos domiciliares orgânicos: práticas e técnicas para a destinação final na cidade de Rio Claro - SP

The present work is the analysis of the practices and techniques currently used in the final allocation given to organic household solid waste in the city of Rio Claro - SP. As the major part of Rio Claro’s household solid waste is formed by the organic fraction, as well as in the rest of the country, this research proposes a study on what is done with that portion of the waste, its treatment and where finally destined, based on the National Solid Waste Politic, recently approved in 2010. With the use of this organic part, for example: as animal feed supplement or compost embodiment for the purpose of producing organic fertilizer, enables the decrease of the percentage of the total destined to dumps and landfills. This total percentage has already been reduced after the popularization of the beneficial recycling programs in Brazil, which are still growing. As cities and the purchasing power of its individuals grow, there is also a consequent growth of waste production by society. The household whether domestic solid waste are lower than Industrial Solid ( RSI ) waste for the production in million tons ( Mton ) quantities , however, those residues are more visible on a daily basis - in cities and periphery as well, due to the inadequate management, - and also offer , as well as industrial and agricultural wastes , several types of harmful effects to the population when managed incorrectly. Therefore, the research aims to assist in the study of Solid Waste Management (MSW) for efficient Urban and Environmental Planning in a midsize city. Thus, this project aims to analyze in the city of Rio Claro, how the allocation of these materials is done and whether these practices denote effective improvement regarding the proper management of waste, in the same way that the recycling chain would allow this effect

Teorias de Spin-1: decomposição em helicidades, redução dimensional e imersão de calibre

We have studied the physical content of the following models: Maxwell, Proca, Self-Dual and Maxwell-Chern-Simons. One method we have used is the decomposition in the so called helicity variables, which can be done in the Lagrangian formalism. It leads to the correct counting of degrees of freedom without choosing a gauge condition. The method separates the propagating modes from the non-propagating ones. The Hamiltonian of the MCS and the AD is calculated. The second method used here is the analysis of the sign of the imaginary part of the residues of the two-point amplitude of the theory, showing that the models analyzed are free of ghosts. We also carry the dimensional reduction of the Maxwell-Chern-Simons and Self-Dual models from D = 2+1 to D = 1 + 1 dimensions. Next, we show that the dimensional reduction of those equivalent models also leads to equivalent models in D=1+1. Even more interesting is the fact, demonstrated here, that those reduced models can also be connected via gauge embedding. So the gauge embedding of the Self-Dual model into the Maxwell-Chern-Simons theory is preserved by the dimensional reduction
