title: Circulating levels of mannose-binding lectin (MBL) in age-related macular degeneration

description: ABSTRACT Purpose: To assess whether the serum levels of mannose-binding lectin of the lectin complement pathway are associated with age-related macular degeneration. Methods: Patients with age-related macular degeneration and age-matched controls underwent full ophthalmologic examination and optical coherence tomography. Using a time-resolved immunofluorometric assay, blood samples were evaluated to determine the serum mannose-binding lectin levels. Results: A total of 136 individuals were evaluated, including 68 patients with age-related macular degeneration (34 exudative and 34 nonexudative) and 68 age-matched controls. The median mannose-binding lectin level was 608 ng/mL (range, 30-3,415 ng/mL) in patients with age-related macular degeneration and 739 ng/mL (range, 30-6,039 ng/mL) in controls, with no difference between the groups. Additionally, the median mannose-binding lectin level was 476 ng/mL (range, 30-3,415 ng/mL) in exudative cases and 692 ng/mL (range, 30-2,587 ng/mL) in nonexudative cases. Conclusions: Serum mannose-binding lectin levels were not associated with age-related macular degeneration or with the exudative and nonexudative forms of the disease.

title: Association between metabolic syndrome and periodontitis: a systematic review and meta-analysis

description: Abstract The aim of the present study was to evaluate the association between metabolic syndrome (MS) and periodontitis (PD), through a systematic review and meta-analysis. Original observational studies assessing the association between MS and PD in adults, published before May 11th (2017), were identified through electronic searches of MEDLINE, EMBASE and Cochrane Library databases. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guideline was used. For studies to be included, they had to mention the criteria used to diagnose MS and to have used at least one clinical measure to diagnose PD. There was no language restriction. Three reviewers independently identified eligible studies for possible inclusion in the systematic review and meta-analysis. The quality of the studies was evaluated by the Newcastle-Ottawa scale for observational studies. A random model meta-analysis was conducted. The strategies used to investigate heterogeneity were sequential analysis, subgroup analysis, univariate meta-regression and sensitivity analysis. Thirty-three studies met the inclusion criteria for the systematic review, and 26 had enough information to be included in the meta-analysis, totaling 52,504 patients. MS and PD were associated with an odds ratio of 1.38 (95%CI 1.26–1.51; I2 = 92.7%; p &lt; 0.001). Subgroup analysis showed that complete periodontal examination (I2 = 70.6%; p &lt; 0.001) partially explained the variability between studies. The present findings suggest an association between MS and PD. Individuals with MS are 38% more likely to present PD than individuals without this condition. Prospective studies should be conducted to establish cause and effect relations between MS and PD.

title: Weed Seed Bank in an Agroforestry System With Eucalyptus in Subtropical Brazil

description: ABSTRACT : Trees can modify the weed seed bank composition and distribution in the cropped area of an agroforestry system. This study aimed at analyzing the eucalyptus (Eucalyptus dunnii) effect on spatial distribution, functional traits abundance and weed seed bank botanic composition in an agroforestry system under no-tillage in Subtropical Brazil. The experiment was conducted in a randomized block design with five replications, and five positions between 4.5-year-old eucalyptus double rows [(4x3) x 20 m] as treatments. Soil sampling was performed at 0-20 cm and the method to quantify and identify seeds was the seedling emergence in trays, inside a greenhouse. Weed phytosociological indices (relative density, frequency and importance), functional traits abundance (life cycle, shade tolerance, reproduction, spread and seed form) and seed densities (m-2) of families and species were evaluated; 17 weed families and 49 species were found. The indices that contributed to the relative importance of families and species differed among the positions between rows. Eucalyptus grown as an intercrop changed the composition and size of the weed seed bank, in a different way for functional traits, families and species depeding on the distance from trees.

title: Herbicidal Activity of Aspergillus niger Metabolites Against Parthenium Weed

description: ABSTRACT: Metabolites of Aspergillus niger, prepared in malt extract (ME) broth and potato dextrose (PD) broth, were evaluated for their herbicidal activity against a noxious parthenium weed (Parthenium hysterophorus). In laboratory assays, original (X) and diluted (½ X) fungal metabolites significantly reduced germination and seedling growth of weed. However, metabolites prepared in ME broth proved to have greater herbicidal activity than metabolites prepared in other growth medium. Original metabolites prepared in ME broth have completely hinder the germination of parthenium seeds; while those prepared in PD broth have reduced germination by 89% over control. In pot trials, one-week, two-week and three-week-old parthenium seedlings were sprayed three times with original and concentrated (2X) metabolites of A. niger prepared in ME broth. Plants were harvested after 40 days of sowing. One-week treatment plants were most susceptible to fungal metabolites spray, followed by two-week and three-week treatment plants, respectively. Original and concentrated metabolites have significantly reduced shoot biomass of one-week-old plants by 57% and 68%, and root biomass by 50% and 75%, respectively. The present study has come to the conclusion that A. niger metabolites prepared in ME broth can effectively control germination and growth of parthenium.

title: SPATIAL VARIABILITY OF THE WATER DEPTH APPLIED BY FIXED SPRINKLER IRRIGATION SYSTEMS

description: Abstract The uniformity of water application is an important factor in the evaluation of sprinkler irrigation systems. This uniformity depends on the type of sprinkler and its operating conditions, such as the arrangement and spacing between the sprinklers in the area; velocity and wind direction during the period of water application and the pressure variation of the irrigation system. The objective of this study was to model, analyze and compare the structure of spatial dependence, as well as the spatial variability of the water depths applied by a sprinkler irrigation system with compensating and non-compensating sprinklers, using geostatistical methods and measurements of accuracy or similarity between the applied water depth maps. The experiment was carried out in an agricultural area, in the city of Cascavel-Paraná-Brazil. A total area of 10 × 10 m was used, with 04 compensating and 04 non-compensating sprinklers installed at a height of 1.5 m. For each type of sprinkler, water levels were measured in 100 collectors spaced 1 × 1 m in the study area in 32 trials. On each test sprinkling was carried out for one hour. The conditions of wind, temperature and air humidity were evaluated at the beginning of each test and at 10-minute intervals with a climatological station. As the geostatistical analysis showed the existence of directional trends, the coordinates were incorporated as covariates to the linear spatial model in the study of the spatial dependence of the average depth of the irrigation water for the two types of sprinklers. The spatial dependence structure that best fits the data when using the compensating sprinklers was the Gaussian model and when the non-compensating sprinklers were used, it was the exponential model. The spatial variability maps of average irrigation water depth (mm) of the trials, obtained by universal kriging, revealed that for both sprinklers there was an increase in the mean level average values in the northwest-southeast direction (135° in the azimuth system) in the area under study, influenced by wind direction and velocity during the execution of the experiment.

title: Increased Foliar Activity of Isoproturon+Tribenuron and Pyroxsulam Against Little Seed Canary Grass and Field Bindweed by Proper Adjuvant Selection in Wheat

description: ABSTRACT: Using an adjuvant to optimize and increase the foliar activity of post emergence herbicides is an acceptable way to reduce their side effects. Field researches were conducted to detect a suitable adjuvant for two post-herbicides namely, isoproturon+tribenuron and pyroxsulam against little seed canary grass (Phalaris minor) and field bindweed (Convolvulus arvensis). Treatments were, isoproturon+tribenuron at 1,025 g a.i. ha-1 (recommended dose) and pyroxsulam at 140.6 g a.i. ha-1 (recommended dose) alone or their reduced dose (75% of the recommended dose) isoproturon+tribenuron at 769 and pyroxsulam at 105.5 g a.i. ha-1, tank mixed with three different adjuvants viz. alkylethersulphate sodium salt at 400, fatty alcohol ethoxylate at 200 and sunflower oil at 1,000 mL ha-1. These treatments were applied at the two to three leaf stages of weeds. All the adjuvants enhanced the efficacy of herbicides; however, maximum herbicide efficacy against P. minor (93.50-97.66%) and C. arvensis (82-100%) was achieved with the application of isoproturon+tribenuron plus alkylethersulphate sodium salt, showing the lowest total weed dry weight (1.48, 0.88 g m-2). The maximum NPK-uptake was associated to the untreated control. Nutrient saving (55-95% N, 43-92% P, 55-95% K) was enhanced by the addition of all adjuvants to herbicides, with better weed control. The maximum yield (41 - 43% increase over weedy check) and yield attributes were recorded with reduced rates of isoproturon+tribenuron plus alkylethersulphate sodium salt, followed by the recommended rate of the same herbicide applied alone. In contrast, sunflower oil with pyroxsulam exerted greater control of little seed canary grass and field bindweed with more yield and yield related traits than alkylethersulphate sodium salt and fatty alcohol ethoxylate with pyroxsulam. These results demonstrated the improvement in the performance of reduced rates of isoproturon+tribenuron with the inclusion of alkylethersulphate sodium salt, with a dose higher than or equal to the recommended dose of the same herbicide, and this is the most cost-effective combination.
