Efeito da tosquia estratégica no comportamento ingestivo de ovelhas Ile de France em pastagem de capim vaquero (Cynodon dactylon cv Vaquero) durante a estação de monta

The experiment evaluated the effects of strategic shearing on feeding behavior in Ile de France ewes in Bermudagrass (Cynodon dactylon) grazing during breeding season. A total of 20 ewes, female, Ile de France breed, 4 years old, 71.10 kg of body weight, in grazing, in a completely randomized design with two treatments and ten repetitions, in which the treatments were composed by shorn and non-shorn animals. The length of the breeding season was 90 days, where the evaluations occurred in the 86th, 87th and 88th day of the experimental period. The grazing time (6.50 hours), rumination (1.59 hours) and idle (3.97 hours) have not changed (P> 0.05) by strategic shearing of the animals, as well as the frequency and the time by frequency grazing (18.33 grazing and 21.49 min/grazing), rumination (10.71 ruminations and 8.83 min/rumination) and idle (18.83 idles and 12.66 min/idle). In the same way, the number of bits per minute (26.37 bits) and the total daily bits (19.116 bits) of the animals were not affected. Thus, the strategic shearing in Ile de France ewes in Bermudagrass grazing during the breeding season does not alter animal feeding behavior.

Impactos socioespaciais do uso e ocupação do solo urbano na área de entorno do Aeroporto Internacional de São Paulo - Guarulhos - Andre Franco Montoro

The construction of the São Paulo International Airport in Guarulhos recorded significant economic growth for the whole region, especially for services and jobs generated. Despite the importance of its presence in Guarulhos, we note the absence of an articulate and committed planning to urban development of the city, mainly in adjacent areas to this airport system planning. Through this stud, we analyzed primarily the major interferences and modifications afforded by its presence in guarulhense spatiality. We found that the government was, to some extent, tolerant to mounting housing in the surrounding area to the airport, from the moment that allowed the diverse urban land use in the place where it was planned to build such equipment. We further note that the airport is developed autonomously to the municipality in which the investments and related works only aim to meet the needs of the enterprise

Photodynamic therapy in root canals contaminated with Enterococcus faecalis using curcumin as photosensitizer

The aim of the study was to evaluate the photodynamic therapy (PDT) effect on root canals contaminated with Enterococcus faecalis using a light emitting diode (LED) light and a curcumin solution (CUR) as photosensitizer (PS). Eighty root canals from uniradicular human teeth were prepared with Protaper Universal rotary system and contaminated with E. faecalis for 21 days. They were divided as: GIa-PDT (CUR, pre-irradiation for 5 + 5 min of irradiation); GIb-PDT (CUR, pre-irradiation for 5 + 10 min of irradiation); GIIa-(CUR, pre-irradiation for 5 + 5 min without irradiation); GIIb-(CUR pre-irradiation for 5 + 10 min of irradiation); GIIIa-(physiological solution and irradiation for 5 min); and GIIIb-(physiological solution and irradiation for 10 min); positive and negative control groups. Collections from root canals were made at time intervals of 21 days after contamination, immediately after treatment, and 7 days after treatment, and submitted to colony forming units per milliter (CFU mL-1) counts. The data were submitted to ANOVA and Tukey multiple comparison tests, at a level of significance of 5 %. In the immediate post-treatment collection, group GIa showed greater bacterial reduction in comparison with GIIa, GIIb, GIIIa, GIIIb, and positive control (P < 0.05). At 7 days post-treatment, GIa showed significant bacterial reduction only in comparison with GIIIa (P < 0.05). Curcumin as sensitizer was effective by 5 min LED irradiation but not by 10 min irradiation PDT using LED light, and curcumin as PS was not effective in eliminating E. faecalis. No difference was observed for periods of irradiation.

Immediate loading of implants installed in a healed alveolar bony ridge or immediately after tooth extraction: an experimental study in dogs

ObjectiveTo compare the sequential healing at immediately loaded implants installed in a healed alveolar bony ridge or immediately after tooth extraction.Material and methodsIn the mandible of 12 dogs, the second premolars were extracted. After 3months, the mesial roots of the third premolars were endodontically treated and the distal roots extracted. Implants were placed immediately into the extraction sockets (test) and in the second premolar region (control). Crowns were applied at the second and third maxillary premolars, and healing abutments of appropriate length were applied at both implants placed in the mandible and adapted to allow occlusal contacts with the crowns in the maxilla. The time of surgery and time of sacrifices were planned in such a way to obtain biopsies representing the healing after 1 and 2weeks and 1 and 3months. Ground sections were prepared for histological analyses.ResultsAt the control sites, a resorption of the buccal bone of 1mm was found after 1week and remained stable thereafter. At the test sites, the resorption was 0.4mm at 1-week period and further loss was observed after 1month. The height of the peri-implant soft tissue was 3.8mm both at test and control sites. Higher values of mineralized bone-to-implant contact and bone density were seen at the controls compared with the test sites. The differences, however, were not statistically significant.ConclusionsDifferent patterns of sequential early healing were found at implants installed in healed alveolar bone or in alveolar sockets immediately after tooth extractions. However, three months after implant installation, no statistically significant differences were found for the hard- and soft-tissue dimensions.

Greater level of physical activity associated with better cognitive function in hemodialysis in end stage renal disease

Patients with chronic kidney disease (CKD) have a lower exercise tolerance and poor functional capacity, carry on a sedentary lifestyle. Another important change found in patients with CKD is cognitive dysfunction. Physical inactivity has been associated with cognitive dysfunction in the general population, but few studies have evaluated this association in CKD. To assess the association between physical activity and cognitive function in patients with CKD on hemodialysis (HD). We evaluated 102 patients undergoing HD. The participants completed the International Physical Activity Questionnaire, which assesses the level of physical activity and the Mini Mental State Examination, used for cognitive screening. Patients were divided into three groups according to their level of physical activity (GI: active/GII: irregularly active/GIII: sedentary). It was applied logistic regression analysis and adopted as outcome variable the presence of cognitive impairment and preserving as independent variables those with a probability of statistical difference between groups of less than 0.1. It was considered statistically significant when p less than 0.05. The groups were similar in age, duration of HD, and smoking. Statistically significant difference regarding race, body mass index, diabetes mellitus, underlying disease and degree of cognitive impairment. Regarding laboratory data, the groups differed in terms of creatinine, glucose, hemoglobin and hematocrit. There was significant association with better physical activity and cognitive function, even adjusting for confounding variables. the highest level of physical activity was associated with better cognitive function in CKD patients undergoing HD.

Effect of an occlusal splint on sleep bruxism in children in a pilot study with a short-term follow up

The aim of the present study was to evaluate the effect of the use of an occlusal splint in children with bruxism in a pilot study with a short-term follow up. Seventeen children were recruited, only nine of whom formed the sample following the application of the inclusion criteria: presence of sleep bruxism for at least six months (based on parents' reports); presence of at least the first permanent molars; and no previous history of treatment involving an occlusal splint. The sample was submitted to a clinical exam. Other sleep problems were screened with the use of a sleep questionnaire filled out by parents before and after 90 days of occlusal splint usage. The children received a flat acrylic resin splint with full coverage of the occlusal surfaces to be worn in the maxilla. In children with erupting teeth, a space was created in the splint to allow normal eruption. After the 90-day period, the absence of sleep bruxism and sleep movements was noted in most of children. Moreover, snoring was reduced in nearly 50%, which raises a new issue to be investigated with regard to the pathophysiology of sleep bruxism. The use of an occlusal splint was effective in reducing the symptoms of sleep bruxism and other sleep problems. Further investigations should be carried out on the relationship between snoring and sleep bruxism in children.

Differential Expression of ADAM23, CDKN2A (P16), MMP14 and VIM Associated with Giant Cell Tumor of Bone

Though benign, giant cell tumor of bone (GCTB) can become aggressive and can exhibit a high mitotic rate, necrosis and rarely vascular invasion and metastasis. GCTB has unique histologic characteristics, a high rate of multinucleated cells, a variable and unpredictable growth potential and uncertain biological behavior. In this study, we sought to identify genes differentially expressed in GCTB, thus building a molecular profile of this tumor. We performed quantitative real-time polymerase chain reaction (qPCR), immunohistochemistry and analyses of methylation to identify genes that are putatively associated with GCTB. The expression of the ADAM23 and CDKN2A genes was decreased in GCTB samples compared to normal bone tissue, measured by qPCR. Additionally, a high hypermethylation frequency of the promoter regions of ADAM23 and CDKN2A in GCTB was observed. The expression of the MAP2K3, MMP14, TIMP2 and VIM genes was significantly higher in GCTB than in normal bone tissue, a fact that was confirmed by qPCR and immunohistochemistry. The set of genes identified here furthers our understanding of the molecular basis of GCTB.

Capacitação de produtores rurais para a melhoria da qualidade do leite cru produzido na região de Araçatuba - SP

This paper reports the results of an extension project carried out at Unesp/Veterinary Medicine course in Araçatuba city with milk farmers of the region. The aim of the project was to supply information to farmers concerning to good quality milk production and, at the same time, to follow up the evolution of milk quality parameters, according to the current Brazilian legislation. Every 45 days, approximately, lectures were presented to milk farmers in Araçatuba city region, approaching chemical and microbiological composition of milk, prevention and detection of mastitis, hygiene proceedings in milking and conservation of milk, cleaning and sanitization operations of facilities and equipments and prevention of adulteration. During the intervals between lectures, milk samples were collected from collective milk cooling tanks and analyzed for microbiological, hygienic and physicochemical tests. The main inadequacies in milk quality were high total bacteria and somatic cells counts, low solids contents and water addition. These problems did not proceed to betterment during the project time. So, it was concluded that the time for instruction of farmers was not enough for a progress in the quality of the milk produced in the region, pointing out the need in continuing this kind of work.
