In tropical regions there is rapid decomposition of plant material deposited on the soil, and the ability to recycle nutrients through this decomposition is one of the most important aspects of cover crops. The aim of this study was to evaluate the yield and nutrient release from forage crops intercropped with maize for silage, and soybean in succession. The study was conducted in the experimental area of Universidade Estadual Paulista, Ilha Solteira campus, Brazil. The experiment consisted of maize for silage intercropped with four forage species (Urochloa brizantha cv. Marandu, Urochloa ruziziensis, Panicum maximum cv. Tanzania, and Panicum maximum cv. Aries) sown in three modalities: in the maize row, together with fertilizer; broadcast at maize sowing; and broadcast in the V4 stage of maize, in a randomized block design in a 4 x 3 factorial arrangement with four replications. The evaluation of nutrient release was performed during the soybean cropping that followed the intercropping by the litter bag method at 30, 60, 90, and 120 days after sowing of soybean. Panicum maximum cv. Tanzania showed higher dry matter yield when sown by broadcasting at maize sowing. Sowing of forages in the maize row, and through broadcasting at maize sowing led to greater dry matter yield for straw formation. Intercropping of maize with forages in the autumn is an alternative for increasing the amount of straw and cycling of macronutrients in a no-till system. Potassium was the nutrient with the greatest accumulation in the forage straws (up to 150 kg ha(-1)), with 100 % release at 90 days after sowing soybean. The forage straws are thus an excellent alternative for cycling of this nutrient. Panicum maximum cv. Tanzania sown by broadcasting at the time of maize sowing showed greater phosphorus cycling (13 kg ha(-1)). Panicum maximum cv. Tanzania broadcast in the V4 stage of maize is the option with least potential for straw production and nutrient cycling, while the other options (forages and sowing modalities) have higher potential for use, at the criteria of machine availability for setting up intercropping with corn.

Research on image processing has shown that combining segmentation methods may lead to a solid approach to extract semantic information from different sort of images. Within this context, the Normalized Cut (NCut) is usually used as a final partitioning tool for graphs modeled in some chosen method. This work explores the Watershed Transform as a modeling tool, using different criteria of the hierarchical Watershed to convert an image into an adjacency graph. The Watershed is combined with an unsupervised distance learning step that redistributes the graph weights and redefines the Similarity matrix, before the final segmentation step using NCut. Adopting the Berkeley Segmentation Data Set and Benchmark as a background, our goal is to compare the results obtained for this method with previous work to validate its performance.

To discuss important characteristics of the use of dental implants in posterior quadrants and the rehabilitation planning. An electronic search of English articles was conducted on MEDLINE (PubMed) from 1990 up to the period of March 2014. The key terms were dental implants and posterior jaws, dental implants/treatment planning and posterior maxilla, and dental implants/treatment planning and posterior mandible. No exclusion criteria were used for the initial search. Clinical trials, randomized and non randomized studies, classical and comparative studies, multicenter studies, in vitro and in vivo studies, case reports, longitudinal studies and reviews of the literature were included in this review. One hundred and fifty-two articles met the inclusion criteria of treatment planning of dental implants in posterior jaw and were read in their entirety. The selected articles were categorized with respect to their context on space for restoration, anatomic considerations (bone quantity and density), radiographic techniques, implant selection (number, position, diameter and surface), tilted and pterygoid implants, short implants, occlusal considerations, and success rates of implants placed in the posterior region. The results derived from the review process were described under several different topic headings to give readers a clear overview of the literature. In general, it was observed that the use of dental implants in posterior region requires a careful treatment plan. It is important that the practitioner has knowledge about the theme to evaluate the treatment parameters. The use of implants to restore the posterior arch presents many challenges and requires a detailed treatment planning.

Abstract Intellectual disability is development atypical conditions that involve issues on a number of factors, such as intellectual skills, adaptive behavior, interactions and social roles. Furthermore, they report higher rates of physical inactivity than the general population, as well as participating less and less of regular physical activity, as they grow and age. The participation of people with intellectual disabilities in physical activity programs promotes, benefits of prevention of diseases, particularly cardiovascular, improvement of intellectual and cognitive ability in addition, regular physical activity promotes reduction of body fat. Therefore the aim of this study was to identify through a systematic review, physical activity programs for adults with intellectual disabilities and their extension of the benefits, limitations and recommendations, moreover, the following objectives: to analyze the types of physical activity programs and determine which is the most suitable for adults with intellectual disabilities, and to determine the benefits that physical exercises programs entail for adults with intellectual disabilities. The initial electronic search resulted in 2808 manuscripts. The predetermined exclusion criteria were: review process of the studies involved reading titles, abstracts and full texts checking. After all these phases, eight manuscripts met the inclusion criteria of the review. Articles presented participants aged between 18 and 67 years with mild to moderate intellectual disability. The intervention period was from 2.5 months studies ranged up to 9 months and the weekly frequency was from one to three times a week. The intervention types differ between the articles analyzed, including leisure and recreation activities, combined exercises of strength and muscular endurance, aerobic activities of hiking, with races and exercise bikes, widespread activities and sports specialization, athletics and...

Patients with Down syndrome have shown different conditions of oral health, and there is a low occurrence of dental caries and a higher susceptibility to periodontal diseases. Thus, this study aimed to evaluate the prevalence of dental caries and periodontal diseases in subjects with Down syndrome. The population was composed of 40 patients with the syndrome, aged 6 to 18 years, of both genders, and an equal number of non-syndromic patients. The periodontal conditions were evaluated by mean of the criteria of PSR and dental conditions were registered following indexes dmft and DMFT. It was found that in children with Down syndrome, the dmft index was 1.17 and DMFT 3.53 while the control group was verified dmft 1.97 and DMFT 2.77. The results of PSR evidenced that 32.5% of children with Down syndrome were periodontally healthy, 65% were gingivitis patients and 2.5% were periodontitis patients, while in the control group, 50% healthy and 50% were gingivitis patients. The results evidenced similar populations of cariogenic cocci between patients with Down syndrome and non-syndromic subjects. It was concluded that the incidence of caries in children with Down syndrome was higher in permanent teeth compared with the control group, while in the occurrence of deciduous teeth caries was slightly higher in the control group, so when children with Down syndrome are subjected to periodic examinations, they present themselves periodontally healthy.

To compare the effect of acupuncture and occlusal splint in the treatment of temporomandibular disorders (TMD) in female patients.Method: Forty-eight female patients (mean age of 39.3±6.8 years) with diagnosed pain in muscles or joint according to RDC/TMD criteria were attended at UNESP - Aracatuba Dental School. Including criteria were reported pain in the chewing muscles and/or in the temporomandibular joint measured by a visual analogue scale (range from 0 to 10) and a reported reduction of the maximum mouth opening. Excluding factors were major occlusal problems, systemic diseases, pregnancy and age below 18 years. After randomization, the first group was treated with acupuncture performed by instructed dentist. The second group was treated with occlusal splint. The outcome variables were assessed at baseline (prior to the first treatment session) and after 1, 3 and 6 months. Primary criteria of success were improvement of mouth opening and pain reduction.Result: Acupuncture group exhibited chewing pain decrease from 5 (at baseline) to 1, 2 and 1 after 1, 3 and 6 months, respectively. In the splint group, chewing pain decreased from 4 to 2, 1 and 2 after 1, 3 and 6 months, respectively. The mouth opening (in mm) increased from 28 (at baseline) to 42, 44 and 46 after 1, 3 and 6 months, respectively in the acupuncture group. In the splint group, mouth opening improved from 29 to 40 after 1 month, and to 43 and 42 after 3 and 6 months. A significant pain reduction was noted for both groups when compared to the baseline (p<.001; Wilcoxon test). Acupuncture group had a significant clinical improvement of opening mouth (Mann-Whitney). Conclusion: The present outcomes suggest a positive association among acupuncture and occlusal splint on the reduction of chewing pain. Acupuncture was more effective in the mouth opening increase.

Normally, the last teeth to erupt are the ones which remain impacted or semi-impacted, and that is the case of the canines. This study aimed to report a few options of treatment, aiming at esthetic and functional maintenance of the affected area before a impacted canine, discussing its indications, contraindications, advantages and disadvantages. This study also aims to emphasize the accessibility the patient would have in case his/her option were one of the approached ways of treatment. In order to identify the studies included or analyzed in this review, a detailed search strategy was performed for the database used: Pubmed, Bireme, Scielo, Cochrane, and Dentistry Oral Science up to 2011. We used non-erupted teeth, canine, and therapeutics as descriptors. The criteria of inclusion were clinical and review articles that approached the theme. Through this review, it was found that the surgeon dentist’s lack of technical and scientific knowledge and the financial impossibility of most population are some hindrances for the establishment of the right planning for the impacted canine.

This study evaluated the oral conditions of 50 cancer patients undergoing head and neck radiotherapy (RT). Clinical examinations were performed before treatment, immediately after 30 days after RT and 6 months after conclusion of RT. Periodontal conditions were evaluated using the criteria of the Periodontal Screening and Recording (SRP) and the need for dental treatment were determined. The presence of xerostomia, mucositis and other side effects of RT were also evaluated. Soon after the beginning of RT, the irradiated patients of radiotherapy developed severe mucositis, dermatitis, dysgeusia, xerostomia and, to a lesser extent, candidosis. After completion of radiotherapy, 68% of patients had level III or IV mucositis. It was found that the development of mucositis hinders oral hygiene and these factors contribute to exacerbate inflammation of periodontal tissues. The data from this study evidenced that the main cause of desertion of RT and of severity of sequelae of RT depends on the oral conditions of patients before starting treatment and the absence of previous dental treatment prior RT.

The pharmaceutical industry invests heavily in promoting their products, and studies suggest that these actions influence doctor’s prescribing. Therefore, this study aimed to analyze the opinions and attitudes of doctors when facing promotional activities of the laboratories. To this end, questionnaires were sent to doctors in Araraquara (SP) containing statements on the subject. Data analysis included study of the association by the chi-square. The results indicated that physicians relate to the propagandists (98%) by considering them useful (55%), but not as a main source update (86%). For 62% of them their prescriptions are not influenced by such relationships, while 24% disagree that doctors in general are influenced as well as new graduates (37%). The majority also disagrees that are influenced by amenities (86%) or free samples (70%) but only 38% believe their colleagues are not influenced by the samples. As for the ethics of these receipts, 57% considered to be appropriate when benefit patients, but only 32% while for personal use. The results show that doctors are vulnerable to the influences of marketing. Therefore, mechanisms and interventions are needed for prescribing drugs solely by criteria of effectiveness, safety, convenience and accessibility to the patient.
