title: Natural Regeneration of Plant Species in Revegetated Mining Areas

description: ABSTRACT Mining activities causes severe environmental degradation. In light of the activity impacts, the legislation determine the development and implementation of Recovery of Degraded Areas Plans (PRDA) as a measure to restore the degraded environment. This study aimed to evaluate the mining areas rehabilitated by planting Eucalyptus sp. or native species, using parameters such as composition, implanted floristic diversity and conditions of natural regeneration. We identified 41 species in 39 genera and 22 families, and noted 16 new regenerating species in the whole area. The floristic survey revealed lower diversity in the area with Eucalyptus sp. than in the area revegetated with native species Thus, the use of native species in degraded land recovery was more appropriate due to the floristic diversity.

title: Assessment of sodium fluoride 2% as a new method of disinfecting extracted human teeth

description: ABSTRACT Objective: Investigate the action of sodium fluoride 2% as a new method of disinfecting/sterilizing extracted human teeth, using E. faecalis. Methods: The survival rate of E. faecalis ATCC 29212 was assessed, in terms of absorbance from the culture media, using a spectrophotometer. The sterilization assessment was carried out in the following groups: Group I (GI) - control; GII - autoclave; GIII - sodium fluoride seven days; GIV - sodium fluoride 14 days. Results: When using the autoclave and sodium fluoride solution (2%), the quantity of bacteria reduced significantly when compared to the control group (p &lt;0.001). Statistically significant differences were also found when the experimental groups were compared with each other (p &lt; 0.001). Conclusion: The results of the present study suggest that sodium fluoride 2% solution can be considered a new disinfection method based on its capacity to reduce the load of E. faecalis.

title: Evaluation of blood glucose in type II diabetic patients submitted to local anesthesia with different vasoconstrictors

description: ABSTRACT Objective: In the dental clinic, the use of local anesthetics containing vasoconstrictors in diabetic patients are still controversial raising some doubts. Thus, the objective of this randomized crossover clinical trial was to evaluate blood glucose, pulse oximetry and heart rate of type 2 diabetic patients when submitted to local anesthesia using prilocaine 3% associated to felypressin 0,03UI / ml (G1) and 2% lidocaine associated to epinephrine 1: 100,000 (G2). Methods: The sample consisted of 20 compensated type 2 diabetic patients (both genders) who were taking oral hypoglycemic drugs. The volunteers underwent two periodontal sessions (scaling) and one of the solutions tested was used in each visit. The cited parameters were evaluated at three different times: before the procedure (T1), 10 minutes after anesthesia (T2) and after 20 minutes (T3). Results: Regarding the blood glucose levels, no statistically significant difference was found in different times between G1 and G2 (p&gt; 0.05). Similarly, regarding pulse oximetry and heart rate, no statistically significant differences were observed in intervals assessed between groups (p&gt; 0.05), presenting values within normal limits. Conclusion: Considering the vasoconstrictors and the volume of anesthetic solution used, the results suggest that the evaluated vasoconstrictors do not alter significantly blood glucose, pulse oximetry and heart rate in compensated type 2 diabetic patients.

title: Demand organization in public oral health services: analysis of a traditional model

description: ABSTRACT Objective: To discuss the municipal experience of the organization and the demand for dental services, based on the guidelines of the Unified Health System (UHS), which point to the structuring of an assistance model based on universality and integrality of care and equity in access to services. Methods: The research, realized in Araçatuba/SP, was based on documentary analysis and interviews with key-informants of the UHS dental service. The traditional court model has a care system for schoolchildren and a basic network with priority for pregnant women. Results: In total, the network has 59 dental surgeons, 31 oral health auxiliaries and 17 Oral Health Teams; however, the school attendance model persists, with 10 professionals attending public schools. Based on the discussions, it is concluded that there are no established criteria for the organization of demand. Conclusion: Most of the attendance occurs by free demand, and the reference and counter-referral system is incipient, damaging the service's resoluteness.

title: Multi-trait and repeatability models for genetic evaluation of litter traits in pigs considering different farrowings

description: SUMMARY We aimed to compare multi-trait and repeatability models to estimate genetic parameters for the traits number of piglets born alive (NBA) and alive at 3 week of age (NP3), litter weight at birth (LW0) and at 3 week of age (LW3), and mean piglet weight at birth (MW0) and at 3 week of age (MW3), considering the first three farrowings of Landrace sows. Heritability (h2) estimates showed an increasing pattern up to the third farrowing for LW0 and MW3. For NBA, NP3, LW3, and MW0 h2 increased from the first to the second and decreased from the second to the third farrowing. In general, heritability estimated in the repeatability model was lower than the mean of the estimates in the multi-trait model. The traits LWO, MW0, and MW3 presented high genetic correlation among different farrowings (0.961–0.997), while NBA, NP3, and LW3 (0.092–0.986) presented irregular values among farrowings. The corrected Akaike information criterion shows that the repeatability model is not indicated for almost all of the studied traits. These results indicate that the multi-trait model is recommended for genetic evaluation of the traits number of piglets born alive and alive at 3 week of age, litter weight and mean piglet weight at birth and 3 week of age, in different farrowings, as different traits.

title: Use of additives in pre-housing and pre-start phases of rising on corporal and grastrintestinal tract weight of broiler chicks

description: SUMMARY The objective of this work was to verify the use of prebiotic or antibiotic in pre-housing and pre-start diets as a way to assess the impact of that nutrition on the corporal weight loss during path from hatchery tofarm, as well as the weight of digestive organs of chicks. Seven hundred and twenty day-old broiler chicks, Cobb 500, were distributed in four treatments in a completely randomized design (diet without additives in the pre – housing and pre – start phases; diet with prebiotic in the pre- housing and pre-start phases; diet with antibiotic in the pre-housing and pre – start phases; Fasting in the pre-housing and diet without additives in the pre-start phase). In the hatchery, the chicks were weighed and were provided to pre-housing diets in the transportation crates. In the experimental house, the birds were weighed again to calculate the weight loss during the course hatchery-farm, and soon after the birds were housed, dividing them into 6 replicates of 30 birds per treatment. The housing density was 10 birds/m2 With 1 and 7 days-old –, a bird per plot was harvested by cervical dislocation for dissection and weighing gastrointestinal organs. The use of prebiotic or antibiotic in pre-housing and pre-starter diets does not contribute in reducing weight loss during the course harchery-farm, as well as their use does not promote greater weight of gastrointestinal organs.

title: Use of Aluminum Silicate Partial Substitution in the Substrate for Seedlings Production Corymbia citriodora

description: ABSTRACT The aim was to verify the aluminum silicate efficiency on substrate composition for Corymbia citriodora seedlings production. The design was a completely randomized design with five treatments and eight replicates. The composition of the substrate consisted of charcoal powder, bovine manure, eucalyptus husk and commercial substrate. It was added on 0 (evidence), 5, 10, 15 and 20% aluminum silicate in the treatments. The seedling quality index, height, the collar diameter, root fresh and dry mass, mean and full foliar area and ratio between root and aerial part dry mass and were not influenced. For aerial fresh and dry mass the evidence were higher than 2.59 and 4.93 respectively. Nevertheless, the addiction until 12.2% showed increasing gains on leaves number. The aluminum silicate to produce C. citriodoraseedlings emergesas a potential target of this alternative residue.

title: Thinning and Site Quality Effects on the Height-diameter Relationship of Pinus taeda

description: ABSTRACT An experiment in pine (Pinus taeda) stands was conducted aiming to evaluate the thinning and site quality effect on the height-diameter relationship. We applied an analysis of variance in randomized blocks, with blocks representing the sites and treatments the mixed thinning, in which systematic and selective modalities were combined, harvesting every fifth row plus 66%, 54%, 42%, 30% and 19% of the lower canopy trees. Thinnings occurred at 8 and 9 years old interval, and diameters and heights of the trees were measured at age 12. We modeled height-diameter relationship and applied the Graybill test for reducing the number of similar selected models in a same block. We found statistical differences between treatments and blocks. As conclusion, height-diameter relationship varies less between treatments but the curve slope tends to reduce in lower quality sites. Same height-diameter equations can be used in different treatments.
