The objective of this study was to characterize and verify the in vitro antitumor activity of essential oils (EOs) extracted from the leaves and flowers of Callistemon viminalis. The EOs were extracted by hydrodistillation using a modified Clevenger apparatus. The identification and quantification of constituents were performed on a gas chromatograph coupled to a mass spectrometer and a gas chromatograph with a flame ionization detector. The antitumoral activity was evaluated by a colorimetric assay (MTS) using different cell lines derived from human tumors (breast, lung, glioblastoma, and melanoma). The major constituents of the EOs of leaves and flowers were similar, only quantitative differences being observed. The compounds 1,8-cineole, α-pinene and α-terpineol were found in concentrations of 50.4%, 25.8% and 8.7% in the EOs obtained from the leaves and 48.8%, 24.5% and 3.9% in the EOs obtained from the flowers, respectively. The cytotoxic activity of the EOs was observed only in melanoma cultures (HT144). Cultures treated for 48 h with EOs from leaves and flowers (200 μg·mL-1) reduced the viability by 40% and 25%, respectively. Thus, the antiproliferative activity of the EO from leaves was more pronounced than the EO from flowers in cells derived from melanoma.

The objective of this study was to evaluate the differences in composition among six brands of conventional soybean and six genetically modified cultivars (GM). We focused on the isoflavones profile and mineral content questioning the substantial equivalence between conventional and GM organisms. The statement of compliance label for conventional grains was verified for the presence of genetic modified genes by real time polymerase chain reaction (PCR). We did not detect the presence of the 35S promoter in commercial samples, indicating the absence of transgene insertion. For mineral analysis, we used the method of inductively coupled plasma-optical emission spectrometry (ICP-OES). Isoflavones quantification was performed by high performance liquid chromatography (HPLC). The results showed no statistical difference between the conventional and transgenic soybean groups concerning isoflavone content and mineral composition. The concentration of potassium, the main mineral component of soy, was the highest in conventional soybeans compared to that in GM soy, while GM samples presented the highest concentrations of iron.

Unconventional vegetables, in general, are plants that have been largely consumed by the population at some point and, because of changes in eating behavior, now present reduced economic and social expression and have lost ground to other vegetables. The objectives of this study were to perform phytochemical screening of the ethanol extracts of Rumex acetosa L., Tropaeolum majus L., Solanum muricatum, Stachys byzantina K. Koch and Solanum betaceum Cav. and evaluate their antioxidant potentials via the methods involving scavaging of the DPPH free radical and the ABTS radical, phosphomolybdenum and reducing power. In phytochemical screening, five species of unconventional vegetables tested positive for tannins;for sesquiterpene, lactones and other lactones. These tests were positive for Tropaeolum majus L. and Rumex acetosa L., Solanum betaceum Cav. and Solanum muricatum tested negative for steroids. Only Solanum betaceum Cav. gave positive tests for flavonoids. Among the five plant species studied, Stachys byzantina K. Koch presented the greatest antioxidant potential in all the methods evaluated.

作者： Arllon José dos Santos Dias Nyelle Priscila Brito Facanha Ed marcos Homobono da silva Evlen Tamille silva do Carmo Charles dos Santos Barros Gabriel Araujo da silva Laboratory of Organic Chemistry and Biochemistry Amapá State University Macapá Amapá 68900-070 Brazil

Fish, as one of the fishery resources, is an important constituent of the diet of the Amazon population, as it is the source of several nutritional components. The present work aimed to characterize the centesimal composition of Plagioscion squamosissimus fillet (n = 10) and Macrobrachium amazonicum meat (n = 82), species acquired in the estuarine region of the state of Amapá, Brazil. Carcass yield, as well as protein, water content, lipids and ashes was determined according to the methodologies proposed by the Adolf Lutz Institute, as well as carbohydrate and caloric determinations. The analyses were performed in triplicate per sample. After comparing with the literature, it was possible to conclude that P. squamosissimus presented a fillet yield of 31.11%± 0.61%, high protein content (15.99 ± 1.26 g/100 g) and humidity (79.40 ± 1.10 g/100 g), moderate contents of mineral residues (1.10 ± 0.07 g/100 g) and carbohydrates (0.96 ± 0.90 g/100 g), low lipid contents (2.29 ± 0.65 g/100 g), as well as low caloric values (385,018.12 J/100 g) and M. amazonicum a meat yield of 44.12%± 8.34%, high levels of protein (22.81 ± 1.72 g/100 g), carbohydrates (1.92 ± 1.61 g/100 g) and mineral residues (1.76 ± 0.78 g/100 g), moderate water content (73.38 ± 0.78 g/100 g), low lipid levels (0.43 ± 0.08 g/100 g), as well as low caloric values (440,786.3 J/100 g). The results obtained in this work can serve as a subsidy in nutritional diets for humans, thus allowing an adequate dietary use of these species.

引用

American Journal of Plant Sciences 2018年第5期9卷 1029-1036页

作者： Renata Gimenes Kathia Fernandes Lopes Pivetta Renata Bachin Mazzini-Guedes marcos Vieira Ferraz Suzana Targanski Sajovic Pereira águila silva Santos Ricardo Tadeu de Faria Lívia Caroline Praseres de Almeida Sao Paulo State University—UNESP Jaboticabal Brazil Federal University of Paraná—UFPR Jandaia do Sul Brazil State University of Londrina—UEL Londrina Brazil

In vitro cultivation is a technique that allows the production of great amount of plants. However, significant losses may occur during the acclimatization period (ex vitro stage). The objective of this study was to evaluate the effect of paclobutrazol, in the Murashige and Skoog culture medium, on growth, development, and survival of Zygopetalum crinitum plants. The experimental design (both in vitro and ex vitro) was completely randomized with four treatments: three paclobutrazol concentrations (0.5;1.0;and 1.5 mg L-1 active ingredient) and the control (without PBZ). Morphological changes promoted by the paclobutrazol application were observed in the seedlings;however, it did not result in higher seedling survival rates of the Zygopetalum crinitum orchid.

The concern in mitigating the negative impact generated by the discharge of nutrients in the receiving water body is a challenge for the sustainable development of Brazilian fish farms. Thus, the purpose of this study was to evaluate the water quality and environmental impact caused by trout farming system effluent with focus on discharge of phosphorus. Sampling was performed on a weekly basis in triplicate from September to November 2010. Sample sites were distributed according to the water flow: upstream from trout farming system, water supply, effluent, artificial wetland, mixing zone and downstream (60 m from effluent). In the field, pH, conductivity, dissolved oxygen, water temperature and turbidity were measured. In laboratory, nitrogen and phosphorus series, chlorophyll a, total solids suspended and their organic and inorganic fractions were analyzed. For the good growth of trout in production system, the abiotic factors described in the water quality monitoring demonstrated acceptable values. Environmentally, after passing through the production system and artificial wetland, there was an increase in concentrations of total phosphorus, total nitrogen, orthophosphate, ammonium, chlorophyll a, total solids suspended and their organic and inorganic fractions (P < 0.05). These results are related with the quality of feed, feeding management and the inefficiency of the artificial wetland. Therefore, it is necessary to use best quality feed to meet the nutritional requirements of trout, maintaining an optimal feed conversion and reducing pollution generated by effluent.

Some breast reconstruction surgeries after mastectomy, or even reductive mammoplasty, may evolve unexpectedly when the areolopapillary complex heals and develop dehiscences, necrosis and delayed healing. The purpose of this case report was to verify the efficacy of photodynamic therapy in wound healing of the areolopapillary complex. This was a case report of a female patient with diabetes, fibromyalgia and diagnosed with breast cancer, with necrotic areolopapillary complex, after debridement, photodynamic therapy started with clobetasol propionate associated with methylene blue and low power laser application. At the beginning of the treatment with photodynamic therapy, the wound had 6 centimeters of diameter, and after 19 sessions, the wound was closed completely with normalization of the color of the nipple. The photodynamic therapy is advancing a lot in healing of infected wounds and complex wounds. It can be said that in this case report, photodynamic therapy was fundamental for the complete healing, being considered a promising treatment and another alternative for dermatofunctional physiotherapists.

Objective: The aim of this study is to check whether there are differences in the distribution of empathy levels in dental students from nine faculties of dentistry Colombia, Panama, Costa Rica and Dominican Republic. Methods: The levels of empathy and matrices of empathy construct matrices are estimated dental students by using the Jefferson Scale of Physician Empathy, the Spanish version for students (S version) culturally validated in Colombia, Panama, Costa Rica and Dominican Republic measured by arbitrator criteria. Cronbach α is estimated. data of empathic orientation of the studied factors between faculties are analyzed and compared by ANOVA and Duncan test and matrices of empathy construct using discriminant analysis. Results: We find that there are differences in levels of empathy between universities, courses, gender and interaction between the Dental Faculty (University) and Course. The comparison between matrices shows unexplained variances and differences observed between the levels of empathy in student populations. Conclusions: Variability in empathy is observed in the studied factors and among student populations. The variability is an empirical finding, but is not possible in this work, to explain why.
