Up-regulation of chemokine C-C ligand 2 (CCL2) and C-X-C chemokine 8 (CXCL8) expression by monocytes in chronic idiopathic urticaria

The disturbed cytokinechemokine network could play an important role in the onset of diseases with inflammatory processes such as chronic idiopathic urticaria (CIU). Our main objectives were to evaluate the relation between proinflammatory chemokine serum levels from CIU patients and their response to autologous skin test (ASST) and basophil histamine release (BHR). We also aimed to assess the chemokine secretion by peripheral blood mononuclear cells (PBMC) upon polyclonal stimulus and to evaluate chemokine CC ligand 2/C-X-C chemokine 8 (CCL2/CXCL8) and Toll-like receptor-4 (TLR-4) expression in monocytes. We observed significantly higher serum levels of the CXCL8, CXCL9, CXCL10 and CCL2 in CIU patients compared to the healthy group, regardless of the BHR or ASST response. The basal secretion of CCL2 by PBMC or induced by Staphylococcus aureus enterotoxin A (SEA) was higher in CIU patients than in the control group, as well as for CXCL8 and CCL5 secretions upon phytohaemagglutinin stimulation. Also, up-regulation of CCL2 and CXCL8 mRNA expression was found in monocytes of patients upon SEA stimulation. The findings showed a high responsiveness of monocytes through CCL2/CXCL8 expression, contributing to the creation of a proinflammatory environment in CIU.

Chiral Templating Activity of Tris(bipyridine)ruthenium(II) Cation in the Design of Three-Dimensional (3D) Optically Active Oxalate-Bridged {[Ru(bpy) 3 ][Cu 2 x Ni 2(1 - x ) (C 2 O 4 ) 3 ]} n (0 ≤ x ≤ 1; bpy = 2,2‘-bipyridine): Structural, Optical, and Magnetic Studies

Three-dimensional oxalate-based {[Ru(bpy)3][Cu2xNi2(1-x)(ox)3]}n (0≤ x ≤ 1, ox = C2O42-, bpy = 2,2‘bipyridine) were synthesized. The structure was determined for x = 1 by X-ray diffraction on single crystal. The compound crystallizes in the cubic space group P4132. It shows a three-dimensional 10-gon 3-connected (10,3) anionic network where copper(II) has an unusual tris(bischelated) environment. X-ray powder diffraction patterns and their Rietveld refinement show that all the compounds along the series are isostructural and single-phased. According to X-ray absorption spectroscopy, copper(II) and nickel(II) have an octahedral environment, respectively elongated and trigonally distorted. As shown by natural circular dichroism, the optically active forms of {[Ru(bpy)3][CuxNi2(1-x)(ox)3]}n are obtained starting from resolved Δ- or Λ-[Ru(bpy)3]2+. The Curie−Weiss temperatures range between −55 (x = 1) and −150 K (x = 0). The antiferromagnetic exchange interaction thus decreases when the copper contents increases in agreement with the crystallographic structure of the compounds and the electronic structure of the metal ions. At low temperature, the compounds exhibit complex long-range ordered magnetic behavior.

Temperaturas óptimas para resembrar especies mesotérmicas sobre c��spedes de Cynodon dactylon en el centro-sur de la provincia de C��rdoba, Argentina

Los objetivos fueron determinar temperaturas medias de suelo (TMS) y mínimas de aire (TMA) adecuadas para realizar resiembras otoñales; evaluar la tasa de crecimiento (TCC) de Cynodon dactylon (Bermuda) que minimice la competencia con la especie resembrada y el comportamiento de distintas especies mesotérmicas en el centro-sur de la provincia de C��rdoba. Se resembró durante 2010 y 2011, en un diseño de parcelas divididas con cinco fechas de siembra (FS) quincenalmente desde principios de marzo, con tres genotipos: Lolium multiflorum cv Axcella, L. perenne y L. perenne cv Excel I. Las temperaturas se midieron entre principios de marzo y hasta que la bermuda entró en dormición, calculando TMA y TMS. En las subparcelas resembradas se registraron calidad visual y cobertura total; además, en la bermuda se calculó la TCC. Las resiembras que lograron valores más altos de calidad visual, cobertura y bajas TCC de la Bermuda, se dieron con TMS entre 18 - 21°C y TMA entre 11,5 - 15,5°C. De acuerdo con los valores medios normales de la región centro-sur de C��rdoba, las temperaturas óptimas se observan entre la segunda década de marzo y primera de abril. Los tres genotipos tuvieron comportamientos similares independientemente de la FS utilizada.

Peligro aviario: Caracterización de la vegetación y determinación de las especies que son atractivas para la fauna silvestre en las areas verdes del Aeropuerto Internacional Augusto C. Sandino, Managua, Nicaragua

Se evaluó la diversidad, estructura y fenología de la flora en las áreas verdes del Aeropuerto Internacional Augusto C. Sandino con el fin de determinar las especies que son atractivas para fauna silvestre de peligro para la aviación, sea por que les provee de alimento o de refugio y hábitat. Y por otro lado, brindar recomendaciones sobre especies con potencial para formar parte de las áreas verdes del aeropuerto. Para ello, se establecieron parcelas anidadas de 2 x 2 m, 5 x 5 m y 10 x 10 m en las cuales se tomaron los datos en los estratos herbáceos, arbustivos y arbóreos respectivamente. Las parcelas se establecieron aleatoriamente en tres sitios dentro del aeropuerto: en el bosque seco al oeste del aeropuerto (BSO), en la Fuerza Aérea (FA) y en el área verde alrededor de la pista de aterrizaje (AVP). Dentro de las parcelas se contaron 117 árboles en todos los sitios, los cuales estaban agrupados en 11 especies, 10 géneros, 8 familias y 4 órdenes. Las especies arbóreas de mayor densidad fueron: Calycophyllum candidissimum(450 individuos/ ha), Albizia niopides (344), Azadirachta indica (289) y Senna siamea (261) y el sitio que presento mayor diversidad y densidad de árboles fue FA. Fueron contados 36 individuos de arbustos, pertenecientes a las especiesCapsicum annum (1) yLantana camara (35). En cuanto a especies herbáceas se contaron 11,845 individuos dentro de las unidades de muestreo, agrupados en 28 especies, 23 géneros, 14 familias y 13 órdenes, siendo el AVP el sitio que registró mayor diversidad y densidad de las mismas. Las especies herbáceas con mayores densidades fueron Cenchrus brownii (256,282.05 individuos/ha), Cynodon dactylon (141,538.46), Digitaria decumbens(106,794.87), Bothriochloa pertusa(51,282.05), Elytaria imbricada (38,846.15) y Panicum maximum (30,192.31). De las 41 especies vegetales, se determinó la fenología completa para 3�, de estas, 6 (�9.35%) florecen y fructifican todo el año:Cordia dentata, Boerhavia erecta, Chamaesyce hyssopifolia, Eleucine indica, Melanthera nivea y Rhynchosia minima. Entre las especies arbóreas mayormente atractivas para la fauna silvestre se determinaron: Albizia niopoides, Manguifera indica, Spondias mombin, Cordia dentata, Guazuma ulmifoliay Calycophyllum candidissimum al ser considerados proveedores de alimentos y refugio a la fauna silvestre, por sus frutos, flores con abundante néctar, copas con poca obstrucción visual (alta densidad de hojas) y ramificaciones horizontales propias para el perchaje de las aves de alto tamaño. Dentro de la vegetación herbáceas se determinaron especies como Tridax procumbensy Tribulus terrestis formando densos tapetes de vegetación con flores atractivas para insectos en el período seco, los cuales a la vez eran focos de atracción para aves insectívoras como: Hirundus rustica (Golondrinas), Quiscalus mexicanus (Zanate), Molotrus aeneus (Tordos), Egretta thula (Garza blanca) que permanecen en las áreas verdes alrededor de la pista de aterrizaje y que peligran colisionar con los aviones. Por otra parte, las especies de la familia Poaceae fueron registradas como proveedoras de granos a las aves del grupo de las Columbidae (Palomas). Especies de gramíneas de gran porte como Panicum maximum, P. antidotale, Sorgum halapensis, además de poseer semillas grandes (>0.3 cm), formaban corredores por donde se desplazan mamífero medianos, reptiles y aves. Dentro del mismo áreas se determinaron dos especies (B. pertusay C. dactylon) que por su baja estatura (menos de 0.3 m), reproducción vegetativa y semillas muy pequeña o ausentes, son ideales para establecer en los alrededores de la pista de aterrizaje. Mediante un ensayo se evaluó su establecimiento, el cual resulto satisfactorio al competir y ganar espacio ante otras monocotiledones y dicotiledonesas, principalmente C. dactylon

Functional immunoglobulin E cross-reactivity between Pas n 1 of Bahia grass pollen and other group 1 grass pollen allergens

Background Grass pollens are major triggers of allergic rhinitis and asthma, but the immunological relationships between pollen allergens of the subtropical Bahia grass, Paspalum notatum, and temperate grasses are unresolved. Objective To assess serum IgE cross-reactivity between subtropical P. notatum and temperate Lolium perenne (Ryegrass) pollen allergens. Methods Serum IgE reactivities of grass pollen-allergic patients with P. notatum, L. perenne and Cynodon dactylon (Bermuda grass) pollen extracts and their respective purified group 1 allergens, Pas n 1, Lol p 1 and Cyn d 1, were compared by immunoblotting, ELISA and basophil activation. Results In a cohort of 51 patients from a temperate region, a high frequency of IgE reactivity with each grass pollen was detected, but reactivity with L. perenne pollen was substantially greater than with P. notatum and C. dactylon pollen. Similarly, serum IgE reactivity with Lol p 1 was greater than with Pas n 1 or Cyn d 1. For seven of eight sera studied in detail, asymmetric serum IgE cross-reactivity was observed; L. perenne pollen inhibited IgE reactivity with P. notatum pollen but not the converse, and IgE reactivity with Pas n 1 was inhibited by Lol p 1 but IgE reactivity with Lol p 1 was not inhibited by Pas n 1 or Cyn d 1. Importantly, P. notatum pollen and Pas n 1 activated basophils in grass pollen-allergic patients from a temperate region, although stimulation was greater by pollen of L. perenne than P. notatum or C. dactylon, and by Lol p 1 than Pas n 1 or Cyn d 1. In contrast, a cohort of 47 patients from a subtropical region showed similar IgE reactivity with P. notatum and L. perenne pollen, and reciprocal cross-inhibition of IgE reactivity between L. perenne and P. notatum. Conclusions Pollen allergens of the subtropical P. notatum, including Pas n 1, show clinically relevant IgE cross-reactivity with pollen allergens of L. perenne but also species-specific IgE reactivity.

Management Guidelines for New Warm-Season Grasses in Australia

After more than 30 years in which ‘Tifgreen’ and ‘Tifdwarf’ were the only greens-quality varieties available, the choice for golf courses and bowls clubs in northern Australia has been expanded to include six new Cynodon hybrids [Cynodon dactylon (L.) Pers x Cynodon transvaalensis Burtt-Davy]. Five of these – ‘Champion Dwarf’ (Texas), ‘MS-Supreme’ (Mississippi), FloraDwarf™ (Florida), ‘TifEagle’ (Georgia), MiniVerde™ (Arizona) - are from US breeding programs, while the sixth, ‘TL2’ (marketed as Novotek™) was selected in north Queensland. The finer, denser and lower growing habit of the “ultradwarf” cultivars allows very low mowing heights (e.g. 2.5 mm) to be imposed, resulting in denser and smoother putting and bowls surfaces. In addition to the Cynodon hybrids, four new greens quality seashore paspalum (Paspalum vaginatum O. Swartz) cultivars including ‘Sea Isle 2000’, Sea Isle Supreme™, Velvetene™ and Sea Dwarf™ (where tolerance of salty water is required) expands the range of choices for greens in difficult environments. The project was developed to determine (a) the appropriate choice of cultivar for different environments and budgets, and (b) best management practices for the new cultivars which differ from the Cynodon hybrid industry standards ‘Tifgreen’ and ‘Tifdwarf’. Management practices, particularly fertilising, mowing heights and frequency, and thatch control were investigated to determine optimum management inputs and provide high quality playing surfaces with the new grasses. To enable effective trialling of these new and old cultivars it was essential to have a number of regional sites participating in the study. Drought and financial hardship of many clubs presented an initial setback with numerous clubs wanting to be involved in the study but were unable to commit due to their financial position at the time. The study was fortunate to have seven regional sites from Queensland, New South Wales, Victoria and South Australia volunteer to be involved in the study which would add to the results being collected at the centralised test facility being constructed at DEEDI’s Redlands Research Station. The major research findings acquired from the eight trial sites included: • All of the new second generation “ultradwarf” couchgrasses tend to produce a large amount of thatch with MiniVerde™ being the greatest thatch producer, particularly compared to ‘Tifdwarf’ and ‘Tifgreen’. The maintenance of the new Cynodon hybrids will require a program of regular dethatching/grooming as well as regular light dustings of sand. Thatch prevention should begin 3 to 4 weeks after planting a new “ultradwarf” couchgrass green, with an emphasis on prevention rather than control. • The “ultradwarfs” produced faster green speeds than the current industry standards ‘Tifgreen’ and ‘Tifdwarf’. However, all Cynodon hybrids were considerably faster than the seashore paspalums (e.g. comparable to the speed diference of Bentgrass and couchgrass) under trial conditions. Green speed was fastest being cut at 3.5 mm and rolled (compared to 3.5 mm cut, no roll and 2.7 mm cut, no roll). • All trial sites reported the occurrence of disease in the Cynodon hybrids with the main incidence of disease occurring during the dormancy period (autumn and winter). The main disease issue reported was “patch diseases” which includes both Gaumannomyces and Rhizoctonia species. There was differences in the severity of the disease between cultivars, however, the severity of the disease was not consistent between cultivars and is largely attributed to an environment (location) effect. In terms of managing the occurrence of disease, the incidence of disease is less severe where there is a higher fertility rate (about 3 kgN/100m2/year) or a preventitatve fungicide program is adopted. • Cynodon hybrid and seashore paspalum cultivars maintained an acceptable to ideal surface being cut between 2.7 mm and 5.0 mm. “Ultradwarf” cultivars can tolerate mowing heights as low as 2.5 mm for short periods but places the plant under high levels of stress. Greens being maintained at a continually lower cutting height (e.g. 2.7 mm) of both species is achievable, but would need to be cut daily for best results. Seashore paspalums performed best when cut at a height of between 2.7 mm and 3.0 mm. If a lower cutting height is adopted, regular and repeated mowings are required to reduce scalping and produce a smooth surface. • At this point in time the optimum rate of nitrogen (N) for the Cynodon hybrids is 3 kg/100m2/year and while the seashore paspalums is 2 to 3 kg/100m2/year. • Dormancy occurred for all Cynodon and seashore paspalum culitvars from north in Brisbane (QLD) to south in Mornington Peninsula (VIC) and west to Novar Gardens (SA). Cynodon and Paspalum growth in both Victoria and South Australia was less favourable as a result of the cooler climates. • After combining the data collected from all eight sites, the results indicated that there can be variation (e.g. turfgrass quality, colour, disease resistance, performace) depending on the site and climatic conditions. Such evidence highlights the need to undertake genotype by environment (G x E) studies on new and old cultivars prior to conversion or establishment. • For a club looking to select either a Cynodon hybrid or seashore paspalum cultivar for use at their club they need to: - Review the research data. - Look at trial plots. - Inspect greens in play that have the new grasses. - Select 2 to 3 cultivars that are considered to be the better types. - Establish them in large (large enough to putt on) plots/nursery/practice putter. Ideally the area should be subjected to wear. - Maintain them exactly as they would be on the golf course/lawn bowls green. This is a critical aspect. Regular mowing, fertilising etc. is essential. - Assess them over at least 2 to 3 years. - Make a selection and establish it in a playing green so that it is subjected to typical wear.

Warm-season greens grass trial - Environmental and management guidelines suited for new and old cultivars

The Horticulture Australia funded project, Management Guidelines for Warm-Season Grasses in Australia (TU05001), has allowed a detailed greens grass study to take place and enabled researchers and superintendents to work together to collect meaningful data on a range of Cynodon dactylon (L.) Pers. x Cynodon transvaalensis Burtt-Davy (Cynodon hybrid) and Paspalum vaginatum O. Swartz (seashore paspalum) cultivars suitable for golf or lawn bowls use. The end result provides superintendents and greenkeepers with additional knowledge to accompany their skills in managing or upgrading their greens to produce a denser, smoother and faster putting or bowls surface. However, neither turfgrass selection nor finely tuned management program will overcome unrealistic expectations (especially in relation to usage), poor growing environments, or limitations due to improper construction techniques.

Foram analisados os custos de produção e o retorno econômico do quilograma de carcaça, de 13 cordeiros Corriedale (C), 14 Bergamácia x Corriedale (BC) e 9 Hampshire Down x Corriedale (HC), em pastagem de Cynodon dactylon e 10 C, 11 BC e 8 HC em confinamento, recebendo ração completa, com 18% de proteína bruta e 72% de nutrientes digestíveis totais, idênticos ao da pastagem. A lotação utilizada foi de 20 cordeiros/ha. No confinamento, considerou-se 0,5m²/cordeiro. A despesa total para terminação dos cordeiros na pastagem foi R$2.382,40 e para terminação em confinamento foi R$2.918,40, com as respectivas receitas de R$3.686,90 e R$4.498,03. O custo de produção do kg de carcaça dos cordeiros confinados (R$2,30), em valor absoluto foi superior, porém, muito próximo dos terminados em pastagem (R$2,26). O retomo econômico para os cordeiros terminados em confinamento (R$1.579,63) foi superior ao dos terminados em pastagem (R$1.304,50), mostrando uma diferença em valores absolutos de R$275,13 a favor dos cordeiros confinados. A produção de carne de cordeiro em confinamento é economicamente viável.

Avaliação agronômica de sete acessos de Hemarthria altissima [poir.]stapf et C.E.Hubb.em Pindamonhangaba, SP

The experiment was carried out to evaluate seven accessions of limpograss Hermathria altissima (PI 364888, NO 158, PI 364863, IPEACO 336, UF 553, UF 347238, and IPEACO 337) as compared to coast-cross grass (Cynodon dactylon), to determine which grasses were best adapted ecologically to conditions at Pindamonhangaba. The experimental design was a randomized block with four replications. Five annual harvests were taken during the three-year experimental period, two in the dry season and three in the rainy season. The higher annual DM yields (kgDM/ ha) were obtained with accessions UF 553 (19996), NO 158 (18745), and PI 347238 (18267). Accessions UF 553 and IPEACO 336 had the most uniform production throughout the year with 37.4 and 33.2% during the dry season, respectively. Coast-cross had the highest percentage of crude protein (10.30%), while limpograss values varied around 7%. It was concluded that accession UF553 was the most promising grass for the Pindamonhangaba region.
