Objective: To analyze and compare the effectiveness of two methods designed for the assessment of esthetic impairment in patients with missing teeth. Material and Methods: Two methods were addressed in this study: 7-level scale (7LS) and AIPE-Odonto/Brasil. Both tools are designed to assess esthetic dental impairment in civil and criminal Courts. One-hundred and thirteen dentists used the tools to assess dental esthetic impairment in four mock cases (one male and three females). The outcomes of their analyses were compared with pre-established gold-standard scores. Chi-square test was used to investigate the influence of dentists’ sex, age, time of experience and forensic knowledge with their outcomes. Results: Dentists’ outcomes were closer to the expected gold-standard scores when AIPE-Odonto/Brasil was used compared to 7LS (p < 0.05). Dentists’ sex, time of experience and forensic knowledge were significantly associated with the scores obtained with both tools (p < 0.05). Conclusions: Comparatively, AIPE-Odonto/Brasil was more effective for the assessment of esthetic dental impairment involving missing teeth compared to the 7LS.

Background: Colles’ fracture is a type of fracture of the distal third of the radius and its most common cause is falling from patient’s own height and, epidemiologically, it is more common in the elderly. Objectives: The main objective of this study is to analyze the epidemiology of Colles’ fracture retrospectively, in patients admitted to fernandes Távora Hospital. Materials and Methods: This retrospective study conducted at the fernandes Távora Hospital used 1030 radiographic images of patients with wrist fractures. Results: (After a careful analysis) It was found that this type of fracture occurred with a greater frequency in age groups of 50 to 69, 60 to 69, and 40 to 49 years old, which corresponds to 59.5% of patients and the most affected sex were females (51.1%). Conclusion: The study concluded that this type of bone injury is more common in people aged 40 to 69 years old, especially in women, because of their geometry and bone composition. It is evident that Colles’ fracture impacts the life of the affected person, therefore, an adequate diagnosis and treatment having utmost importance.

The aim of this study was to investigate the effects of different temperatures, light regimes, and seed moisture contents on germination of the palm Euterpe precatoria, in the Arecaceae family. For the study of light and temperature, the experimental design was entirely randomized;treatments were arranged in a 6 × 2 factorial scheme [six temperature conditions (20°C, 25°C, 30°C, 35°C, 20°C - 30°C, and 25°C - 35°C) combined with two light regimes (light and darkness)] with four replications composed of 25 seeds each. For the seed moisture content study, the experimental design was entirely randomized with five seed moisture contents (27%, 20%, 13%, 12%, and 11%), to which they comprised 5 treatments, and four replications with 25 seeds each. Number of germinated seeds was recorded daily until germination was steady. Data were submitted to variance analysis;for the first experiment, means were compared by the Tukey test (p ≤ 0.05) and, for the second, the regression analysis was performed. The temperature at 20°C promoted highest germination percentage and germination rate for E. precatoria seeds, under either light or darkness;seeds were tolerant up to 11% moisture content.

Forensic aesthetic facial damage—AFD expert’s valuation is a concerning matter in court as expressively vary in between experts. In fact, differences can be quite significant suggesting examiners age, sex and professional qualification may influence this valuation. Aiming to offer a systematic and more objective evaluation, some methods for assessing AFD had been proposed lately. Known as Aesthetic Impairment Impact Perception (AIPE), Cobo-Plana’s revised methodology (2010) was idealized to minimize the examiner’s subjectivity by means of answering an ordered sequence of questions related to the specific damage perception. This research aims to access AFD perception differences (simulated cases) in between Lawyers, Heath professionals (Physicians and Dental surgeons) and general professionals (laypeople) under AIPE methodology in order to allow a better comprehension of AFD when dealing with forensic expertise cases. Within Groups perceptions varied (p < 0.05) when evaluating lesions below “important” severity grade. Raters over 35 Years age scored higher AFD lesions, and rater’s sex (as an independent variable) did not express any significant difference in AFD scoring. The tendency of under-rating AFD lesions below very important severity grade was observed being a matter of major concern considered their prevalence and the effective consequences involved to the victim. These results recommend extra caution when performing AFD evaluation and consequently expertise reports, claiming a more judicious analysis based on consolidated standards and suggest, examiners to be more perceptive to physical damage evaluation in order to include social perceptions and reactions, mainly, victims feelings and constrains over their aesthetic loss.

The objective of this study was to analyze the effect of the seasons and indol butyric acid (IBA), as well as the preparation of IBA solutions on rooting growth of “Fine Time” chrysanthemum cuttings. The first experiment was arranged in a 4 × 2 factorial scheme: IBA concentrations (0, 1000, 2000 and 3000 mg·L-1) during summer and winter with 4 replicates of two pots and six cuttings per pot. In the second experiment, the storage of IBA solution (1000 mg·L-1) at 15°C was studied with four replicates of 10 cuttings per plot in a period of four weeks. In the third experiment, dilution and supply of IBA (1000 mg·L-1 or 1000 mg·kg-1) were studied;there were eight treatments: (1) IBA mixed with industrial talc;(2) IBA diluted in 50% alcohol and oven dried at 30°C;(3) IBA diluted in 50% alcohol and oven dried at 70°C;(4) IBA diluted in NaOH and supplied via aqueous solution;(5) IBA diluted in acetone and supplied via aqueous solution;(6) IBA diluted in alcohol 92.8% and supplied via alcoholic solution;(7) IBA diluted in alcohol 50% and supplied via alcoholic solution;(8) IBA mixed and supplied via lanolin;with four replicates of 10 cuttings per plot. Twenty-one days after cutting implementation, the following variables were evaluated: rooting percentage, number, average length and root dry mass. Statistical analysis and time-of-year averages were compared using the Tukey test at 5%;polynomial regression for IBA concentration and preparation data. The means of dilution and delivery were compared by the Scott-Knott test. Treatment with IBA at a concentration of 3000 mg·kg-1 resulted in 90% rooting in the winter and 100% in the summer for all treatments. Results suggest the concentration of 2000 mg·L-1 in the summer and 2000 and 3000 mg·L-1 during the winter provided better quality for the root system. Cuttings treated with IBA diluted in 50% alcohol and oven dried at 30°C showed higher number, length and vigor of the roots.

The essential oils from Mentha piperita, Cymbopogon citratus, Rosmarinus officinalis, Peumus boldus and Foeniculum vulgare were extracted by hydrodistillation and characterized and quantified by GC-MS and GC-DIC. The oils induced hemolysis with all the doses evaluated (0.6 to 1.8 μL), and the diameters of the halos varied between 9 and 15 mm. Pre-incubation of P. boldus oil with Bothrops jararacussu venom resulted in potentiation of venom-induced hemolysis (30%) (proteases and phospholipases A2). The essential oil from M. piperita (0.6 μL) inhibited venom-induced hemolysis by 45%, whereas 0.6 μL of R. officinalis oil increased the hemolysis by 20%. For the essential oil from F. vulgare, 100% inhibition of activity (0.6 and 1.2 μL) was observed. The application of C. citratus oil induced hemolysis with all the volumes evaluated. Phospholipase activity induced by the venom was only inhibited (10%) with the 0.6 μL volume of R. officinalis oil. The oils from M. piperita and F. vulgare (1.8 μL) and C. citratus oil (0.6 μL) potentiated the phospholipase activity. The results highlight the need for a broad characterization and regulation of the use of natural products, because they can have therapeutic or toxic actions.

The coagulating potential of the crude extract from the barbatimao bark for the treatment of dairy effluent was assessed and compared with industrial coagulants such as aluminum sulfate (inorganic coagulant), the crude extract of black wattle bark (used in the manufacture of natural organic coagulants), and gallic acid (the main constituent of condensed tannins). The aqueous extract of barbatimao was obtained by refluxing for 12 h, and the black wattle was provided by a producer of natural coagulants. The determinations of total phenolic compounds and tannins in the extracts were performed by the Folin-Ciocalteu method and precipitation with casein, respectively. The treatment of the effluent with coagulant was performed by the Jar-Test. After testing, the effluent was evaluated for turbidity, total solids, and biochemical oxygen demand (BOD). A higher content of phenolic compounds (19.81% mg of gallic acid/g extract) was observed in the barbatimao extract than in the black wattle extract (14.24% mg of gallic acid/g extract). However, the extracts contained the same amount of tannins, 13.95% for the barbatimao extract and 12.89% for the black wattle extract. A 63%, reduction in BOD was observed for the effluent treated with barbatimao extract, 35% for the black wattle extract, 58% for gallic acid and 60.59% for the treatment with aluminum sulfate. Treatment with gallic acid caused a 98% reduction in the turbidity of the effluent;with aluminum sulfate, a 97% reduction was obtained;with barbatimao extract, 96%, and with black wattle extract, 93%. The barbatimao extract was shown to be a potential coagulant for dairy effluents.

Bredemeyera floribunda Wild (Polygalaceae), also known as pau-de-ovo is a medicinal plant used to treat snakebites, as tonic and fortifiers to treat fatigue and exhaustion. The aim of the present study was to document the knowledge of herbal sellers in the preparation of the so-called “B. floribunda fortifier” and to compare the plant root content with the recommended nutritional values and the permitted limit for medicinal plants. The study revealed that, unlike other regions of Brazil, in the Midwest region, the root of the plant is used as food to treat fatigue and exhaustion. The contents in B. floribunda root decreased in the following order: Ca > K > P > Na > Fe > Mg > Si > Mn > Zn > Cu. Daily intake of 30 grams of B. floribunda roots are considered as an excellent source of Cr, Cu, Mn and Se for people 19 to 50 years of age according to the RDA. In addition, Cu and Fe showed content above the established limit for medicinal plants stipulated by other countries. The root of the plant has low K, Mg, P, Na and Zn content. When the contents in roots of the plant are below the oral dose of reference, consumption of this plant can be considered safe and without risk to human health. On the other hand, concentration of elements such as Cu, Fe, Ni, Al, Cr and Se exceeding the allowable limit may cause serious health problems due to prolonged ingestion and large amounts consumed daily. The Brazilian legislation does not establish a permissible limit of macro- and micro-elements in medicinal plants;thus, the results presented in this study will contribute to the Brazilian public health policy on medicinal plants.
