Abstract: This work aimed to study the quality of frozen pulp, manufactured and marketed in Boa Vista - RR, through physico-chemical analysis. It were selected six Agroindustries that produce and market pulp in establishments located in Fair Passar o, supermarkets and home of juices, identified by the letters A, B, C, D, E and F. The variables studied were: soluble solids, titratable acidity and vitamin C, of the flavors: acerola, caja, cupua u, guava, soursop and passion fruit. The experiment was conducted in completely randomized design, being analyzed six brands of fruits pulps and six different fruits, with three replicates. The observed results demonstrate that none of the companies processing fruit pulp detail their identification inaccordance with the legislation. In the variables studied, only the cupua u pulp brands C and D and soursop brands B, C, D and E were in accordance with the technical regulation for fixing the identity and quality standard. Considering the variables in question, it was found that variations in the levels encountered and not adequacy of these standards could be minimized by the standardization of raw materials and processes used. =Objetivou-se com o presente trabalho estudar a qualidade de polpas congeladas, fabricadas e comercializadas no município de Boa Vista – RR, por meio de análises físico-químicas.

Abstract: Immature and mature collagens presents in oral lesions of rat were evaluated. Oral ulcer was chemically produced on the tongue of 56 male rats and, then, treated by topic application of solution of propolis (experimental group) and saline solution (control group). The animals were treated for seven days and sacrificed at 2nd, 7th, 14th, and 21th days. Samples of the treated area were processed in laboratory and stained by picrosirius. Mean areas of immature collagen in the experimental group at 2nd, 7th, 14th, and 21th days were, respectively, 60.41 μm ± 18.3, 67.2 μm ± 16.2, 90.77 μm ± 6.64 and 56.48 μm ± 7.56. Mean areas of mature collagen evaluated for this same time were: 39.58 μm ± 18.31, 32.8 μm ± 16.2, 9.23 μm ± 6.64 and 43.53 μm ± 7.56. There was a significant difference between the mean areas of mature and immature collagens between groups at 2nd and 14th days (Tukey’s test, p≤0.05). Propolis used in this study had contributed positively to the wound healing of oral ulcers of rats, probably, due to concentration and alcoholic vehicle.

Abstract: Introduction: Chloramphenicol is an antibiotic with controversial use during pregnancy for easily crossing the placental barrier and achieving high concentrations in the fetus. Objective: The aim of this study was to evaluate the teratogenic potential of chloramphenicol to induce cleft palate in rats. Material and methods: 10 female Wistar rats were used to perform the mating, allocated into two groups: G1– 5 female rats received 0.5 mg/kg of sodium chloride intramuscularly from the 14th to the 17th day of pregnancy (control); G2 – 5 female rats received 0.5 mg/kg of chloramphenicol intramuscularly from the 14th to the 17th day of pregnancy.Cesareans were performed in the 20th day of pregnancy. The fetuses’ heads were removed and clinically examined with the aid of a stereoscopic magnifying glass for the diagnosis of cleft palate.Results: The fetuses of G1 or G2 did not present cleft palate.Conclusion: Chloramphenicol does not have the teratogenic potential to induce cleft palate in rats.

Abstract: INTRODUCTION: Tooth movement is initially characterized by an acute sterile inflammation, followed by sequential multiple reactions in the periodontal ligament in response to biomechanical forces. Pharmacological agents such as corticosteroids may affect the course of orthodontic movement. Scientific studies show antagonistic actions of these drugs on bone resorption during tooth movement. OBJECTIVE: To review the literature about the effect of corticosteroids on orthodontic tooth movement. CONCLUSION: Patients should be questioned regarding the use of these drugs in the orthodontic practice and for those who use them, the orthodontic treatment should be differentiated, with longer intervals between visits and periodic X-rays due to the delay in bone formation observed in some scientific studies. INTRODU O: a movimenta o dentária é caracterizada, inicialmente, por uma inflama o aguda estéril, seguida por rea es múltiplas sequenciais no ligamento periodontal em resposta às for as biomecanicas. Agentes farmacológicos, como os corticosteroides, podem alterar o curso da movimenta o ortod ntica. Os estudos científicos demonstram a es antagonistas dessas drogas sobre a reabsor o óssea durante a movimenta o dentária. OBJETIVO: realizar revis o de literatura sobre a a o dos corticosteroides no movimento dentário ortod ntico. CONCLUS O: os pacientes devem ser questionados quanto ao uso dessas drogas na clínica ortod ntica e, para aqueles que fazem uso, o tratamento ortod ntico deve ser diferenciado, com intervalos maiores entre as consultas e solicita o periódica de radiografias devido ao atraso na neoforma o óssea observado em alguns estudos científicos.

Abstract: The use of by-products of wild animals for the production of handicrafts is a common practice among indigenous peoples. Natives prefer to hunt birds because of the beauty and diversity of their feathers. In the Brazilian Northeast, this practice involves several hunting techniques, according to the species type. This research aimed to list the species of birds used in the handicraft of the Truká indigenous people and to characterize the techniques used to capture birds employed by the native hunters in the four ethnic settlements in the backlands of Pernambuco and Bahia. The information was obtained through semi-structured interviews applied to 23 indigenous artisans, in the villages Truká of Cabrobó, Orocó, Sobradinho and Paulo Afonso. Four capture techniques, slingshots, firearms, and traps have been identified, such as the trap and the trapdoor. The traps are the most commonly used technologies in the study area. In addition to crafts, informants have indicated the use of bird species in food, traditional medicine and domestic breeding as pets.

Abstract: This paper presents an empirical survey of energy-related investment decisions made by private households in Germany. The investment behaviour is segmented and discussed by applying the milieu approach. The decision makers are clustered in certain lifestyles, as represented by the Sinus-Milieus? from the Sinus Institute. To analyse the relationship between the lifestyles of house owners and their energy-related investment decisions, telephone interviews were conducted in order to acquire data on currently installed heating systems and preferences for future heating systems in private residential buildings. The results of the survey support the hypothesis of a link between lifestyles and the energy-related investment behaviour. Based on the observed relationship between lifestyles and decisions on energy technologies, predictions of energy trends in private residential buildings can be improved. In addition, the knowledge about specific development paths allows the utilisation of the information for information campaigns and the promotion of energy supply technologies which lead to lower CO2-emissions.
