title: ENVIRONMENTAL FRIENDLY METHODS FOR REGIOSELECTIVE IODINATION OF THE 3,7,3’,4’-TETRAMETHOXY-QUERCETIN

description: Halogenated compounds are valuable substrates for the field of organic synthesis and more specifically as reagents for coupling reactions. Environmental friendly procedures for regioselective iodination is the aim of this study, using four different methods previously described in the literature, that embrace green chemistry concepts, to obtain the 6- and 8-iodo-isomers of 3,7,3’,4’-tetramethoxy-quercetin. As traditional column chromatography does not resolve the mixture of isomers, the regioselectivity for iodination was quantified by use of HPLC. The use of a protic polar solvent improves selectivity for formation of the 8-iodo- isomers (tipically, I2, LiOH, MeOH, 3 h, 54% yield), while the use of a polar aprotic solvent or in the absence of a solvent favors formation of the 6-iodo- isomer (typically, I2, K2CO3, without solvent, 5 min, 60% yield). Twenty-one reaction procedures were investigated, five of which selectively gave the 6,8-diiodo-derivative. To the best of our knowledge, selective methods for the synthesis of this compound have not been described in the literature. The best condition was the neat reaction with N-iodo-succinimide with 68% yield in just a few minutes. All product yields are after column chromatography using silica gel, and characterized by usual methods, including 1H-NMR, 13C-NMR, IR and MS-TOF.

title: Ascites and Encapsulating Peritonitis in Endometriosis: a Systematic Review with a Case Report

description: Abstract Endometriosis can have several different presentations, including overt ascites and peritonitis; increased awareness can improve diagnostic accuracy and patient outcomes. We aimto provide a systematic review and report a case of endometriosis with this unusual clinical presentation. The PubMed/MEDLINE database was systematically reviewed until October 2016. Women with histologically-proven endometriosis presenting with clinically significant ascites and/or frozen abdomen and/or encapsulating peritonitis were included; thosewith potentially confounding conditionswere excluded.Our search yielded 37 articles describing 42 women, all of reproductive age. Ascites was mostly hemorrhagic, recurrent and not predicted by cancer antigen 125 (CA-125) levels. In turn, dysmenorrhea, dyspareunia and infertility were not consistently reported. The treatment choices and outcomes were different across the studies, and are described in detail. Endometriosis should be a differential diagnosis of massive hemorrhagic ascites in women of reproductive age.

title: Yield and water use of cherry tomato under water availability and potassium doses

description: ABSTRACT The objective of this study was to evaluate the yield and water use of cherry tomatoes under soil water availability and potassium (K) doses in a greenhouse. The experiment was conducted in randomized blocks in a 52 fractional factorial design, corresponding to five levels of water availability and five K doses, with 13 combinations (4-0; 4-250; 4-500; 14-125; 14-375; 24-0; 24-250; 24-500; 34-125; 34-375; 44-0; 44-250; 44-500) (kPa-mg dm-3) and four replicates. A drip irrigation system with semi-automated irrigation control was used. The analyzed variables were shoot dry matter, number of fruits, yield, water consumption and water use efficiency. Highest cherry tomato yield occurs at soil water tension of 24 kPa and K dose of 290 mg dm-3. Soil water tension of 44 kPa and K dose of 290 mg dm-3 allow for higher water use efficiency in cherry tomato. Cherry tomato yield and water use are influenced by soil water availability and K doses in greenhouse.

title: RELATIONSHIP BETWEEN BONE MINERAL DENSITY AND BODY COMPOSITION IN ELDERLY

description: ABSTRACT Objective: To evaluate the association between bone mineral density (BMD) and body composition in healthy older adults at different skeletal sites. Methods: We analyzed 87 medical records and BMD along with the body composition of men ranging from 60 to 87 years of age (mean: 68.5, standard deviation: 6.5). Inclusion criteria were normal BMD values (T-score greater than or equal to -1.0) and body mass index within normal or overweight range (18.5 to 29.5 kg/m2). Body composition was evaluated using bone densitometry with dual-energy X-ray absorptiometry (DEXA) in a LUNAR-DPX apparatus. Results: Greater lean mass, fat mass, and soft tissue was associated with better BMD values in older adults, and higher age was associated with poorer BMD. Conclusion: Body composition (lean and fat masses and soft tissue) in older men is positively associated with BMD at all body sites (arms, legs, and trunk). Level of Evidence II; Prognostic studies - Investigating the effect of a patient characteristic on the outcome of disease.

title: Contamination of soil and pineapple fruits under fertilization with sewage sludge

description: ABSTRACT Sewage sludge is rich in organic matter and nutrients for the plants, and can be used in pineapple production, but there are few studies with scientific evaluation of possible inorganic and biological contaminants in pineapple plantations. In view of the above, this study aimed to evaluate the contamination of the soil and in fruits of pineapple fertilized with sewage sludge. The study was conducted in the municipality of Janaúba-MG. Treatments were arranged in a randomized block design, with four replicates, in a 2 x 5 factorial scheme, consisting of two different fertilizers: sewage sludge (SS) and mineral fertilizers (MF), and five pineapple varieties (Pérola, Vitória, Smooth Cayenne, MD-2, Fantastic IAC). Nitrogen was adopted as the base element to calculate the sewage sludge dose in the pineapple crop. Fertilization with sewage sludge increased the Zn and Cu contents in the soil and the Zn content in the leaves of the pineapple plants. Sewage sludge did not change the contents of As, Pb, Ba, Cu and Zn in the fruit, and Cr, Ni and Cd contents were not detected by the method used. Pineapple fruits did not show microbiological contamination above the limits established by the Brazilian legislation.

title: Bird diversity in an urban ecosystem: the role of local habitats in understanding the effects of urbanization

description: ABSTRACT: Urbanization causes environment changes that directly affect biotic diversity, and understanding the relationship between fauna and urban features is a key aspect of urban planning. Birds are particularly affected by urbanization. Noise levels, for instance, negatively affect birds’ behavior and social communication, while the presence of green areas promotes bird diversity. The effects of urbanization could differ according with the level of urbanization, and our goal was to understand how bird species assemblages are related to urban features in an intermediate stage of urbanization (a city in Brazil with 2,470 inhabitants/km²). We used canonical correspondence analysis (CCA) and generalized linear models (GLM) analyses to assess how bird species assemblages are affected by urban features (e.g., noise level, abundance of buildings) as well as habitat features (e.g., vegetation cover). Despite we did not find a clear pattern of urbanization both the urban and habitat features had, even if weak, an effect on bird species distribution. Bird species distribution was spatially correlated, and we identified three groups: 1) grassland and wetland species; 2) forest species; 3) species tolerant to habitat degradation. Species richness was positively related to the proportion of trees, abundance of people and presence of buildings, and negatively affected by higher levels of noise. The abundance of species decreased as noise levels increased, but the proportion of green areas (open or forest vegetation) had a positive effect. Agreeing with previous research, our study shows that noise levels and vegetation cover seem to be the best predictors of diversity in urban areas. Nevertheless, the presence of particular habitats (wetlands, grasslands, woodlots), patchily distributed in the urban matrix, could buffer the effects of urbanization on birds. These habitats should thus be taken into account in urban planning.

title: Gall-inducing insects of deciduous and semideciduous forests in Rio Grande do Sul State, Brazil

description: ABSTRACT Galls are specific changes induced by insects on plant organs mainly through increases in plant cell number and/or size. Gall diversity is easy to recognize in the field because gallers are mostly species-specific, and thus each gall morphotype can be a proxy for a galling species. Insect galls are virtually unknown in Seasonal Deciduous and Semi-Deciduous forests of southern Brazil. Here, galls and host plants were surveyed between 2015 and 2017 in four forest fragments of Rio Grande do Sul State in these two vegetation types, in secondary-growth and areas under restoration. We recorded 89 gall morphotypes, with gallers belonging to Lepidoptera and Diptera, with the latter represented mainly by Cecidomyiidae. Galls were associated to 46 plant species in 27 families. Asteraceae, Piperaceae, Fabaceae, Myrtaceae and Lauraceae were the richest families in terms of galls, whilst Piper aduncum and Mikania glomerata were superhosts. Most galls occurred in leaves and shoots. The most common shapes were fusiform, globoid and lenticular. Forty-eight gall morphotype records are new for both Rio Grande do Sul and Brazil, an expressive number considering only two seasonal forest types sampled and few sampling points, showing how important surveys still are for these little know fauna both in taxonomic and ecological terms.

title: Do changes in riparian zones affect periphyton growth and invertebrate colonization on rocky substrates in Atlantic Forest streams?

description: ABSTRACT: We evaluated the growth of periphyton and colonization of sterilized cobbles by invertebrates in three coastal streams of the Atlantic Forest (Southeast Brazil) that differ in the conservation level of riparian zones. Because of differences in light availability and water temperature, we hypothesized the growth of periphytic algae would be higher in the most altered stream. Consequently, invertebrate assemblages would differ among streams. Cobbles with similar sizes were ashed and incubated for 7, 15, 30, 45 and 60 days in the studied streams. Despite periphyton growth was faster in the most altered stream, contents of chlorophyll-a did not differ among streams. A total of 954 individuals (98% insects) belonging to 36 taxa was found. Invertebrate density was higher and increased throughout the experiment in the preserved stream, while invertebrate biomass was higher on the initial sampling intervals (7 and 15 days). A stream effect on invertebrate assemblages was observed after the 15th day and 17 taxa were found only in the preserved stream. Leptophlebiidae (Ephemeroptera), Hydroptilidae, Helichopsychidae, Leptoceridae (Trichoptera) and Orthocladiinae (Diptera) showed specificities with the assemblages found in the preserved stream and no taxa proved to be an indicator of the assemblages found in the altered streams. These results showed that changes in the riparian zones of Atlantic Forest streams did not affect the content of chlorophyll-a on rocky substrates, but the growth of periphyton influenced the density and structural composition of invertebrate assemblages. Our findings partially support the proposed hypothesis and conform to the notion of the importance of periphyton community for the colonization of exposed substrates by invertebrates and for evaluating the consequences of anthropogenic changes in ecosystem functioning and aquatic communities.

title: Brachiaria enrichment with selenium-coated urea

description: ABSTRACT: Selenium (Se) fertilization in grazing to biofortification of animal products have been carried out in low Se soils. The objective of this study was to increase the Se content in the biomass of Brachiaria spp.with urea coated with Se. The experiment was performed in a typical Hapludox soil under greenhouse conditions. A completely randomized block design with four replicates in a factorial structure with two cuts and six Se doses (0, 10, 20, 40, 80, and 160gha-1) was used. The Brachiaria brizantha demonstrated the absence of changes in higher harmful doses without modifying the activity of glutathione peroxidase enzyme. We concluded that enrichment of Brachiaria brizantha with coated urea is obtained with 34.5gha-1of Se.
