Ability of trees for microclimatic regulation the San Ginés de la Jara park (Cartagena)

[SPA] El presente trabajo tiene por objetivo demostrar la capacidad del arbolado de producir sombra y sus efectos sobre la generación de confort térmico a los usuarios del parque urbano de San Ginés de la Jara. El arbolado puede modificar el microclima local de manera sensible mediante la generación de sombra, pero esta capacidad depende de las características propias de cada especie (tamaño, forma y frondosidad) y de su gestión. Se realizaron mediciones sobre el arbolado y las sombras proyectadas mediante fotografía y un sistema de información geográfica (SIG) con el que se determinó el área total sombreada por el arbolado (Obra derivada de LiDAR-PNOA 2016 CC-BY 4.0 scne.es). Adicionalmente, se realizó un estudio de capacidad de generación de confort térmico mediante termografías y el cálculo de los índices térmicos PET (ºC) y PT (ºC). [ENG] The present work aims to demonstrate the ability of urban forest trees for shading and its effects on the generation of thermal comfort for users of the urban park of San Ginés de la Jara. Trees can modify the local microclimate in a significant way by generating shade, but this ability depends on the characteristics of each species (size, shape, and leafiness) and its management. To study it, different measurements were made on the trees and their projected shadows by photography and a geographic information system (GIS) which led determine the total area shaded by the trees (work derived from LiDAR-PNOA 2016 CC-BY 4.0 scne.es). Additionally, a thermal comfort generation capacity study was carried out using thermography and the calculation of the thermal indices PET (ºC) and PT (ºC).Este trabajo ha sido posible gracias al apoyo financiero y técnico de la empresa Actúa Servicios y Medioambiente S.L

Association of anti-citrullinated vimentin and anti-citrullinated ?-enolase antibodies with subsets of rheumatoid arthritis.

[EN] Objective. To determine whether the anti? citrullinated vimentin peptide 60?75 (anti?Cit-vimentin) and the immunodominant anti?citrullinated -enolase peptide 1 (anti?CEP-1) antibodies are associated with subsets of patients with rheumatoid arthritis (RA) independently of the associations between anti?cyclic citrullinated peptide (anti-CCP) antibodies and clinical features of RA. Methods. The 3 antibody types were quantified by enzyme-linked immunosorbent assay (ELISA) in serum samples from 521 patients with RA and 173 healthy controls of Spanish ancestry. Genotypes for HLA?DRB1 alleles and rs2476601 in PTPN22 were available for these patients and controls plus an addi- tional 106 healthy controls. A combined analysis of the 3 antibodies was conducted using stratified contingency tables and logistic regression models. Results. A differential, particularly strong, and independent association was observed between the pres- ence of anti?Cit-vimentin antibodies and the presence of shared epitope (SE) alleles, specifically in patients carrying 2 SE alleles, and between the presence of anti? Cit-vimentin antibodies and the prevalence of joint erosion. Associations were observed between anti? CEP-1 positivity and the presence of HLA?DRB1 and PTPN22 risk alleles and their additive interaction. These associations were not accounted for by the anti- CCP status. Conclusion. Our results indicate that the 2 anti- bodies against citrullinated peptides analyzed in this study add specific information beyond that obtained with the anti-CCP status. They define subgroups of patients with RA in which genetic factors have different weight and there is an observed difference in the prev- alence of erosions.Fondo de Investigaci?n Sanitaria del Instituto de Salud Carlos III (ISCIII)European Regional Development Fund of the European UnionXunta de GaliciaFundaci?n Espa?ola de Reumatolog?

Association of Systemic Lupus Erythematosus Clinical Features with European Population Genetic Substructure

Systemic Lupus Erythematosus (SLE) is an autoimmune disease with a very varied spectrum of clinical manifestations that could be partly determined by genetic factors. We aimed to determine the relationship between prevalence of 11 clinical features and age of disease onset with European population genetic substructure. Data from 1413 patients of European ancestry recruited in nine countries was tested for association with genotypes of top ancestry informative markers. This analysis was done with logistic regression between phenotypes and genotypes or principal components extracted from them. We used a genetic additive model and adjusted for gender and disease duration. Three clinical features showed association with ancestry informative markers: autoantibody production defined as immunologic disorder (P = 6.8×10(-4)), oral ulcers (P = 6.9×10(-4)) and photosensitivity (P = 0.002). Immunologic disorder was associated with genotypes more common in Southern European ancestries, whereas the opposite trend was observed for photosensitivity. Oral ulcers were specifically more common in patients of Spanish and Portuguese self-reported ancestry. These results should be taken into account in future research and suggest new hypotheses and possible underlying mechanisms to be investigated. A first hypothesis linking photosensitivity with variation in skin pigmentation is suggested

Divalent and Multivalent Activation in Phosphate Triesters: A Versatile Method for the Synthesis of Advanced Polyol Synthons

This is the peer reviewed version of the following article: Thomas, C. D., McParland, J. P. and Hanson, P. R. (2009), Divalent and Multivalent Activation in Phosphate Triesters: A Versatile Method for the Synthesis of Advanced Polyol Synthons. Eur. J. Org. Chem., 2009: 5487–5500. doi:10.1002/ejoc.200900560, which has been published in final form at http://doi.org/10.1002/ejoc.200900560. This article may be used for non-commercial purposes in accordance with Wiley Terms and Conditions for Self-Archiving.The construction of mono- and bicyclic phosphate trimesters possessing divalent and multivalent activation and their subsequent use in the production of advanced polyol synthons is presented. The method highlights efforts to employ phosphate tethers as removable, functionally active tethers capable of multipositional activation and their subsequent role as leaving groups in selective cleavage reactions. The development of phosphate tethers represents an integrated platform for a new and versatile tether for natural product synthesis and sheds light on new approaches to the facile construction of small molecules

Lack of replication of higher genetic risk load in men than in women with systemic lupus erythematosus

Introduction: We aimed to replicate a recent study which showed higher genetic risk load at 15 loci in men than in women with systemic lupus erythematosus (SLE). This difference was very significant, and it was interpreted as indicating that men require more genetic susceptibility than women to develop SLE. Methods: Nineteen SLE-associated loci (thirteen of which are shared with the previous study) were analyzed in 1,457 SLE patients and 1,728 healthy controls of European ancestry. Genetic risk load was calculated as sex-specific sum genetic risk scores (GRS(s)). Results: Our results did not replicate those of the previous study at either the level of individual loci or the global level of GRS(s). GRS(s) were larger in women than in men (4.20 ± 1.07 in women vs. 3.27 ± 0.98 in men). This very significant difference (P < 10(-16)) was more dependent on the six new loci not included in the previous study (59% of the difference) than on the thirteen loci that are shared (the remaining 41%). However, the 13 shared loci also showed a higher genetic risk load in women than in men in our study (P = 6.6 × 10(-7)), suggesting that heterogeneity of participants, in addition to different loci, contributed to the opposite results. Conclusion: Our results show the lack of a clear trend toward higher genetic risk in one of the sexes for the analyzed SLE loci. They also highlight several limitations of assessments of genetic risk load, including the possibility of ascertainment bias with loci discovered in studies that have included mainly women

Increased Expression of Fatty-Acid and Calcium Metabolism Genes in Failing Human Heart

Heart failure (HF) involves alterations in metabolism, but little is known about cardiomyopathy-(CM)-specific or diabetes-independent alterations in gene expression of proteins involved in fatty-acid (FA) uptake and oxidation or in calcium-(Ca(2+))-handling in the human heart.RT-qPCR was used to quantify mRNA expression and immunoblotting to confirm protein expression in left-ventricular myocardium from patients with HF (n = 36) without diabetes mellitus of ischaemic (ICM, n = 16) or dilated (DCM, n = 20) cardiomyopathy aetiology, and non-diseased donors (CTL, n = 6).Significant increases in mRNA of genes regulating FA uptake (CD36) and intracellular transport (Heart-FA-Binding Protein (HFABP)) were observed in HF patients vs CTL. Significance was maintained in DCM and confirmed at protein level, but not in ICM. mRNA was higher in DCM than ICM for peroxisome-proliferator-activated-receptor-alpha (PPARA), PPAR-gamma coactivator-1-alpha (PGC1A) and CD36, and confirmed at the protein level for PPARA and CD36. Transcript and protein expression of Ca(2+)-handling genes (Two-Pore-Channel 1 (TPCN1), Two-Pore-Channel 2 (TPCN2), and Inositol 1,4,5-triphosphate Receptor type-1 (IP3R1)) increased in HF patients relative to CTL. Increases remained significant for TPCN2 in all groups but for TPCN1 only in DCM. There were correlations between FA metabolism and Ca(2+)-handling genes expression. In ICM there were six correlations, all distinct from those found in CTL. In DCM there were also six (all also different from those found in CTL): three were common to and three distinct from ICM.DCM-specific increases were found in expression of several genes that regulate FA metabolism, which might help in the design of aetiology-specific metabolic therapies in HF. Ca(2+)-handling genes TPCN1 and TPCN2 also showed increased expression in HF, while HF- and CM-specific positive correlations were found among several FA and Ca(2+)-handling genes

Identification of a novel susceptibility locus at 13q34 and refinement of the 20p12.2 region as a multi-signal locus associated with bladder cancer risk in individuals of European ancestry

Candidate gene and genome-wide association studies (GWAS) have identified 15 independent genomic regions associated with bladder cancer risk. In search for additional susceptibility variants, we followed up on four promising single-nucleotide polymorphisms (SNPs) that had not achieved genome-wide significance in 6911 cases and 11 814 controls (rs6104690, rs4510656, rs5003154 and rs4907479, P < 1 × 10−6), using additional data from existing GWAS datasets and targeted genotyping for studies that did not have GWAS data. In a combined analysis, which included data on up to 15 058 cases and 286 270 controls, two SNPs achieved genome-wide statistical significance: rs6104690 in a gene desert at 20p12.2 (P = 2.19 × 10−11) and rs4907479 within the MCF2L gene at 13q34 (P = 3.3 × 10−10). Imputation and fine-mapping analyses were performed in these two regions for a subset of 5551 bladder cancer cases and 10 242 controls. Analyses at the 13q34 region suggest a single signal marked by rs4907479. In contrast, we detected two signals in the 20p12.2 region—the first signal is marked by rs6104690, and the second signal is marked by two moderately correlated SNPs (r2 = 0.53), rs6108803 and the previously reported rs62185668. The second 20p12.2 signal is more strongly associated with the risk of muscle-invasive (T2-T4 stage) compared with non-muscle-invasive (Ta, T1 stage) bladder cancer (case–case P ≤ 0.02 for both rs62185668 and rs6108803). Functional analyses are needed to explore the biological mechanisms underlying these novel genetic associations with risk for bladder cancer
