A seqüência mafra superior \ Rio Do Sul inferior (Grupo itararé, permocarbonífero) em sondagens testemunhadas da região de mafra (SC), Margem Leste da Bacia do Paraná

The Permo-Carboniferous Harare Group crops out in the Matra area, represented by Campo do Tenente, Mafra and Rio do Sul formations; they correspond in subsurface to Lagoa Azul, Campo Mourão and Tacïba formations. A composite sampling of the Group was performed through drilling of six wells, which average 60 m in depth; three of them cored the depositional sequence here designated as Upper Mafra\Lower Rio do Sul. The Upper Mafra Formation were sampled by TC-4 and BR-5 wells, and it consists of three units: the lower two are sandy, glacial-deltaic and fluvial-deltaic in origin, corresponding to a lowstand tract. The last unit is composed of two dirtying-upward successions of sandstone, diamictite and rhythmite, interpreted as deglaciation/transgressive events, and well represented in BR-5 drilling. The Lower-Rio do Sul Formation (Lontras Shale) is formed by two marine units: the lower one is represented by shale and bioturbated siltstone which culminate the previous deglaciation, transgressive succession, while the upper one, sampled by SL-2 well, is formed by shale and thin, turbidite sandstone, attributed to a highstand tract.

The mandibular lingula's position in children as a reference to inferior alveolar nerve block

Purpose: The objective of this study was to evaluate the position of the mandibular lingula (ML) to provide data for inferior alveolar nerve block techniques in children. Methods: One hundred fifty-four panoramic radiographs of 7- to 10-year-old boys and girls were analyzed. Measurements were taken from the ML to the occlusal plane, and the percentile distances of the ML to ramal borders were determined. Results: The distance between the ML and the occlusal plane showed a gradual increase, but only in the male group was it statistically significant. MLs ratio position on the ramus remained constant in all analyzed groups. In the 7-year-old group, the ML was observed above the occlusal plane in 70% of girls and 55% of boys. That percentage reached 85% of all children by age 10. Conclusions: The mandibular lingula's ratio position remained constant. Inferior alveolar anesthesia should be administered at least 6 mm above the occlusal plane in 7- to 8-year-old children, while 10 mm could be indicated for 9- to 10-year-old children. The mandibular lingula should be considered a reliable reference for further studies of inferior alveolar nerve block techniques.

Facies sedimentares e ambientes deposicionais da Formação Barbalha no vale do cariri, bacia do araripe, nordeste do Brasil

The Aptian Barbalha Formation represents the first unit of the post-rift sequence of the Araripe Basin and crops out at the slopes of the Aranpe plateau in the eastern part ot Aranpe Basin. The unit has also been named Kio da Batateira Formation, but this name is here used in its original definition as Batateira Beds, an interval of great lateral continuity and characterized by the presence of bituminous shales of the Alagoas Stage (P-270 palynological biozone). This paper presents the results of a stratigraphic analysis carried out along the outcrop belt in order to establish the facies architecture and to interpret deposicional environments of the siliciclastic Barbalha Formation. Detailed stratigraphic vertical sections were measured and correlated. They allowed the recognition of two depositional sequences characterized by fining upward arrangement of facies, beginning with fluvial deposits and ending with lacustrine deposits at their tops. The end of the first cycle is represented by black shales and brecciated limestones of the Batateira Beds that record a geologic event of regional magnitude and serve as meaningful long-distance stratigraphic mark. The second deposicional sequence overlies disconformably the Batateira Beds and begins with clast-supported conglomerates, which are covered by a succession of fluvial sandstones and minor intervals of pelitic rocks. The sandstone content diminishes towards the top and the upper part of the unit is characterized by the presence of ostracode-rich green shales. The Barbalha Formation is conformably overlaid by Late Aptian lacustrine limestones belonging to the Crato Member of the Santana Formation.

Avaliação da inclinação do incisivo inferior através da tomografia computadorizada

Introduction: Orthodontics has always used lateral cephalometric radiographs (LC) as the main examination in the orthodontic diagnosis and treatment plan. The determination of incisor position is part of most cephalometric analysis, including Tweed analysis. However, all radiographic images have limitations, since it is a bidimensional image of a tridimensional structure and overlapping of bone and dental structures often occurs. Computed tomography (CT) allows a trustworthy diagnostic, mainly for its tridimensional images possibility. In this situation it seems reasonable to question the classic cephalometric analysis, creating factors of comparison with computed tomography data. Aim: For this, it was considered the evaluation of the angle between the long axis of the inferior incisor and the mandibular plane (IMPA) in the lateral cephalograph and in the computed tomography. Methods: Nineteen patients, selected for orthodontic treatment, had constituted the sample of this study, 12 female and 7 male, with ages between 16 years and 4 months and 28 years and 2 months. After the collection of data made by two examiners, statistical analyses for the attainment of the errors intra and inter-examiners had been made, using level of significance of 5%. Results and Conclusion: It was concluded that IMPA can be measured in the lateral cephalometric radiographs with trustworthiness, even that its values were smaller when compared with the computed tomography.

Alimentação de Serrasalmus maculatus (Kner, 1858) (characiformes; serrasalmidae) no trecho inferior bacia do rio Sorocaba, São Paulo, Brasil

The aim of this study was to discuss aspects of the diet of Serrasalmus maculatus. Fish were collected using gill nets, whose lengths measured 100 m and mesh diameters varied from 3 to 8 cm. A total of 107 individuals were collected. Their length varied from 62 to 210 mm. They were mainly represented by female and immature individuals. No individual was caught in temperatures below 21°C. Four feeding item categories were observed: fish muscle pieces, parts of fish fins, plant fragments, and insects. Comparisons made among individual length classes revealed some significant differences within stomach consumed contents. Individuals whose length exceeded 165 mm consumed only parts of fish muscles and plants. The food availability in the environment and the class lengths amplitude may, however, have influenced the results, in which ontogenetic differences should not be precisely observed.

Transformação cística como consequência de terceiro molar inferior incluso

The permanence of impacted third molar in the jaws can cause many pathological alterations, amongst them the appearance of odontogenic cysts. The paradental cyst appearance and evolution next to a mandibular included third molar was diagnosised in radiograph routine follow-up, and its evolution and treatment are described. Are discussed the aspects related with the preventive removal to the impacted third molars and the necessity to institution a plan of treatment based in clinical history and radiograph in order to establish a preventive protocol the alterations caused by these impactions. The indication of extraction of impacted third enclosed can be a way to preventing the appearance of these and otherspathologies associates to these lesions.

Variação das características hidrosedimentares e geomorfologia do leito do Rio Ivaí - PR, em seu curso inferior

In the present study were observed changes in morphology of the bed of the lower course of the river Ivaí, made by bathymetric surveys, granulometric analysis and measures the flow velocity. Changes made considerable changes in relation to flow and bad load. The study was conducted in the last 110 km of the river Ivaí, between the municipalities Tapira and Icaraíma - PR. In this section the channel flows with meandering pattern, embedded in sandstone Caiuá and sediment modern of its flood plain. This is the only major river in the state that so far has no modifications, making it an important site for studies of fluvial geomorphology.

Incomplete mandibular fracture after lateralization of the inferior alveolar nerve for implant placement

PURPOSE: The present case describes an inferior alveolar nerve lateralization for implant placement that caused mandible fracture a few days after surgery. CLINICAL REPORT: In this case, a 56-year-old female patient who had a severely atrophied jaw and showing bone height less than 7 mm from the bone crest and the mandibular canal was submitted to surgery lateralization of the inferior alveolar conducted with piezzo. Even with all postoperative care, the patient suffered an incomplete fracture of the mandible a few days after lateralization of the inferior alveolar nerve for implant placement. The patient was treated with soft diet and medications for pain and antibiotics, besides removing the implant associated with the fracture. CONCLUSION: It is suggested that this procedure may be conducted in 2 operative periods: firstly, the lateralization of the inferior alveolar; and secondly, after a period of 3 months, the implant placement in a situation of more bone stability.

Relação entre o desempenho e período de recuperação após enfermidades ósseas do membro torácico distal de cavalos puro sangue inglês

It is well established in the literature that musculoskeletal injuries are important compromising agents in the performance of Thoroughbred horses. In Brazil, there are no studies on the interrelation between lay-up period post-injury and retirement of racehorses due to musculoskeletal injures. The aim of this study is to determine the relationship between rehabilitation times of track injures and variables of prior race performance and later return to competitions. The radiographic reports and athletic history of 416 thoroughbreds during the period between 2003 and 2006 were examined; they were selected based on continued presentations after injury diagnosis. The temporal variables (post-injury rehabilitation time) and performance variables (race score before and after injury) were evaluated by multivariate correspondence analysis of the data and represented in perceptual maps. Correspondence was observed between most of the animals that had a short lay-up post-injury and variables that denote decline in subsequent performance. Considering the integrity of the bone healing process as crucial for the horse to be able to handle later training routines and competitions, shortening this period could lead to an imbalance of the bone repair metabolism, thus resulting in performance decline and compromise of the horse athletic career.
