title: Fluoride concentrations in salt marketed in Managua, Nicaragua

description: Abstract Nicaraguan legislation has established that fluoride concentrations in salt should be 200–225 mg/kg, but no report describes fluoride concentrations in salt marketed in this country. We evaluated the fluoride concentrations in 33 packages of salt of 11 brands (n = 3 each) purchased in Managua, Nicaragua. According to the package information, 9 of the 11 brands were fluoridated. Six aliquots of each package were weighed (mean 2.5 ± 0.3 g; n = 198) and dissolved in 0.025 g/ml water. Duplicates of 1.0 ml of solutions prepared were buffered (1:1; v/v) with TISAB II. Fluoride concentrations were determined with ion-specific electrode, calibrated with standard solutions (0.25–16.0 μg F/ml) mixed (1:1; v/v) with TISAB II added to 0.025 g (p.a.) NaCl/ml. The mean (± standard deviation, n = 3) fluoride concentrations of two fluoridated brands were in accord with Nicaraguan law (209.8 ± 48.0 and 211.4 ± 26.0 mg F/kg), and those of five brands were below the mandated range (131.0 ± 34.3, 180.6 ± 12.3, 184.6 ± 34.8, 190 ± 47.2, and 199.0 ± 18.9 mg F/kg); two brands contained only traces of fluoride. The two non-fluoridated brands had traces of fluoride. The findings show that the surveillance system for the salt fluoridation program in Nicaragua should be improved, as most salt analyzed violated the requirements of the national legislation.

title: Weed Flora of Citrus Orchards and Factors Affecting its Distribution in Western Mediterranean Region of Turkey

description: ABSTRACT: Citrus is an important export commodity, mostly grown on Mediterranean and Aegean coasts of Turkey. Weeds are hidden foes impairing citrus productivity. Limited knowledge of weed distribution and factors affecting the distribution are among major hurdles in successful weed management. In this study, weed flora of citrus orchards and factors affecting its distributions in Mugla province of Turkey were determined. Sixty orchards were surveyed in spring and autumn seasons of 2010 and 2011. Data relating to frequency, coverage and density of weed species were recorded. Soil samples (0-30 cm depth) were collected and analyzed for physicochemical properties. Climatic variables, altitude and soil properties were correlated with weed flora. Sixty-eight weed species belonging to 30 families were documented. Higher number of weed species (54) was recorded in spring season compared with autumn (29 weed species). Annuals and therophytes were the most dominant growth and life forms, respectively. Canonical Correspondence Analysis (CCA) to correlate soil properties and weed vegetation data yielded three distinct groups dominated by phosphorus, sand and silt contents, which affected weed distribution. CCA to correlate vegetation data and weather attributes produced two distinct groups affected by altitude and precipitation. Generally, cosmopolitan weeds adapted to different ecosystems were observed during the survey. Keeping in view the spatial variability of soil and nature of weeds, site-specific/orchard-specific weed management practices are recommended to be opted for successful weed management.

title: Antifungal, antibiofilm, and antiproliferative activities of Guapira graciliflora Mart

description: Abstract: The aim of this study was to evaluate in vitro the antifungal, antibiofilm and antiproliferative activities of the extract from the leaves of Guapira graciliflora Mart. The phytochemical characterization of the extract was performed using electrospray ionization mass spectrometry (ESI-MS). The antimicrobial activity of the extract and its fractions was evaluated using the broth microdilution method against species of Candida. The inhibition of C. albicans biofilm was evaluated based on the number of colony-forming units (CFU) and metabolic activity (MTT). The antiproliferative activity of the extract and its fraction was evaluated in the presence of human tumor and non-tumor cells, and the cytotoxicity of the extract was determined on the RAW 264.7 macrophage line – both using the sulforhodamine B method. The phytochemical characterization indicated the presence of the flavonoids rutin and kaempferol. The extract and the methanol fraction exhibited moderate antifungal activity against C. albicans, C. krusei, and C. glabrata, and strong activity against C. dubliniensis. In the biofilms at 24 and 48 hours, the concentration of 12500 µg/mL of the extract was the most effective at reducing the number of CFU s/mL (44.4% and 42.9%, respectively) and the metabolic activity of C. albicans cells (34.6% and 52%, respectively). The extract and its fractions had no antiproliferative effect on the tumor lines tested, with mean activity (log GI50) equal to or greater than 1.71 µg/mL. Macrophage cell viability remained higher than 80% for concentrations of the extract of up to 62.5 µg/mL. G. graciliflora has flavonoids in its chemical composition and demonstrates potential antifungal and antibiofilm activity, with no evidence of a significant change in the viability of human tumor and non-tumor cell lines.

title: Studies on Nodulating Capacity of Some Forage Legumes Grown Alone or in Mixtures

description: ABSTRACT: A pot experiment was conducted to study the nodulating capacity of some forage legumes. Birdsfoot trefoil (Lotus corniculatus L), sainfoin (Onobrychis viciifolia Scop.) and subterranean clover (Trifolium subterraneum L.) were grown in pure culture (100%) and in mixtures with tall fescue (Festuca arundinacea Schreb.) in the ratios: birdsfoot trefoil + tall fescue (50:50%); sainfoin + tall fescue (50:50%); subterranean clover + tall fescue (50:50%); birdsfoot trefoil + subterranean clover + tall fescue (33:33:33%); sainfoin + subterranean clover + tall fescue (33:33:33%). Birdsfoot trefoil from the crops cultivated in pure stands showed the highest nodulation rating (31), followed by sainfoin (26) and subterranean clover (26). Nodulation rating in binary mixtures with grass component increased to 16.1% for birdsfoot trefoil and to 23.1% for subclover. Birdsfoot trefoil, both in pure stands and in mixtures, showed the highest phosphorus use efficiency for nodule formation.

title: Interference of the Association Oxyfluorfen + Flumioxazin and the Addition of Mineral Oil on a Phytosociological Survey

description: ABSTRACT: Phytosociological studies are extremely important for the management of weeds in cultivated areas. Thus, the goal of this work was to evaluate the interference of mineral oil associated with oxyfluorfen and flumioxazin, through the phytosociological survey of weeds. Therefore, this experiment was conducted in a 2 x 5 + 1 factorial design and with four replications; the following oxyfluorfen + flumioxazin associations were evaluated: 240 + 50, 192 + 40, 144 + 30, 96 + 20 and 48 + 10 g a.i. ha-1, with and without the addition of mineral oil, including a control sample without application. Thirty days after the application, plant density, frequency and abundance of species were determined, and so were frequency, density and relative abundance, as well as the importance value index. Results indicate that the application of the mixture oxyfluorfen + flumioxazin, regardless of the addition of the mineral oil, provided a great population of Poaceae. The species Digitaria horizontalis and Brachiaria decumbens showed a higher importance value index in all treatments. Families with greater representation as for number of species were Poaceae, Asteraceae, Fabaceae and Rubiaceae. The addition of oil and different doses of the mixture oxyfluorfen + flumioxazin did not affect the population of weeds, compared to the mixture without mineral oil.

title: Integrated Role of Row Spacing and Adjuvant to Reduce Herbicide Dose in Maize Under Semi-Arid Conditions

description: ABSTRACT: Crop row spacing adjustment and adjuvants have a significant role in decreasing herbicide cost and environmental damage by reducing herbicide application rate. A field study was conducted to assess the impact of two row spacing values and reduced herbicide rates along with adjuvant on weeds in maize in 2014 and 2015. The experiment consisted of atrazine plus mesotrione plus halosulfuran methyl (pre-mixed herbicide) at label rate (719.2 g a.i. ha-1); reduced rates of 75% (539.4 g a.i. ha-1) and 50% (359.6 g a.i. ha-1) alone and in combination with alkyl ether sulphate at 396.8 mL ha-1 as an adjuvant along with weedy check in maize sown at 60 and 75 cm row spacing. Alkyl ether sulphate increased weed control efficacy (13-35%) of the pre-mixed herbicide. Herbicide along with adjuvant provided effective weed control at 60 cm as compared to 75 cm apart sown maize. The most effective control of weeds, and increase in maize grain yield (33-45% as compared to non-treated control) and net income were obtained by the pre-mixed herbicide at 539.4 g a.i. ha-1 (75% of recommended rate) with adjuvant and pre-mixed herbicide at 719.2 g a.i. ha-1 (recommended dose) without adjuvant. The results revealed that the rate of pre-mixed herbicide can be reduced by up to 25% of the recommended field rate by the addition of alkyl ether sulphate as an adjuvant at 60 cm row spacing of maize to increase maize yield and net income.

title: Individuals with special needs and their families’ oral health-related quality of life

description: Abstract To evaluate the impact of dental caries among Brazilian individuals with special health care needs (SHCN) on their families’ oral health-related quality of life (OHRQoL). A cross-sectional study was carried out with a population-based sample of 227 subjects who were enrolled from the ACOLHER-PNE project conducted at the Fluminense Federal University. Parents/caregivers answered the Brazilian version of the 14-item Family Impact Scale (B-FIS) to assess the impact on family's quality of life (QoL). The main independent variable was dental caries experience, diagnosed according to the World Health Organization (WHO) criteria. The DMFT/dmft score was categorized into 0 = caries free; 1–2 = low; 3-4 = moderate; and ≥ 5 = high experience. Mother's schooling, age, sex, SHCN conditions, and socioeconomic factors were the other independent variables. QoL was measured through FIS domains and total score. Statistical analyses was performed using the Kruskal Wallis and Mann Whitney U tests and Poisson regression (p&lt;0.05). The impact values observed in moderate and high caries experience were significantly higher than those found in subjects without caries and low level of parental emotions. Parents’ years of schooling showed more impact on total score and on parental emotions. Older subjects showed significantly higher impact on total score and in all domains. The multivariate model demonstrated that families of older subjects (&gt; 8 years old) experience a higher impact level compared to younger subjects (PR: 2.43; 95%CI: 1.80–3.29, p = 0.001). High caries experience and other socioeconomic factors were not associated with a greater negative impact on parents’ QoL.
