Late Jurassic oceanic crust and Upper Cretaceous Caribbean plateau picritic basalts exposed in the Duarte igneous complex, Hispaniola

Four distinct rock units have been recognized near El Aguacate, in the Janico-Juncalito-La Vega area of the Duarte complex (Dominican Republic): (1) serpentinites crosscut by numerous diabasic dikes, (2) basalts interbedded with Late Jurassic ribbon cherts, (3) picrites and ankaramites relatively enriched in incompatible trace elements, and (4) amphibolites and gneissic amphibolites chemically similar to Oceanic Plateau Basalts. Similar Ar-Ar ages of late magmatic amphibole from a picrite, and hornblende from an amphibolite (86.1 +/- 1.3 Ma and 86.7 +/- 1.6 Ma, respectively), suggest that the Duarte picrites are contemporaneous with the Deep Sea Drilling Program Leg 15 and Ocean Drilling Program Leg 126 basalts drilled from the Caribbean oceanic plateau. These basalts are associated with sediments containing Late Cretaceous faunas. Sr, Nd, and Pb data show that enriched picrites and amphibolites are isotopically similar to mafic lavas from previously described Caribbean plateau and Galapagos hotspot basalts. Major element, trace element, and lead isotopic features of Late Jurassic basalts and diabases are consistent with those of normal oceanic crust basalt. However, these basalts differ from typical N-MORB because they have lower epsilon Nd ratios that plot within the range of Ocean Island Basalts. These rocks appear to represent remnants of the Caribbean Jurassic oceanic crust formed from an oceanic ridge possibly close to a hotspot. Later, they were tectonically juxtaposed with Late Cretaceous slices of the Caribbean-Colombian plateau.

10 años de repositorios cooperativos

El 1999 van començar els treballs que van culminar amb la posada en funcionament de TDX / TDX, el primer dipòsit creat a Espanya. Des de llavors la cooperació entre les universitats de Catalunya i la Biblioteca de Catalunya ha permès posar en funcionament 5 repositoris cooperatius (TDX / TDR, RECERCAT, RACO, MDC i MDX). Això ha estat possible per una divisió de tasques en la qual les biblioteques són les responsables de la introducció de continguts, el CESCA de la preparació del programari i el maquinari i el CBUC de la coordinació dels processos.Aquest taller dividit en 4 parts, té la finalitat d'explicar les diferents fases que han viscut els repositoris cooperatius, les actuacions dutes a terme en aquests 10 anys per omplir de contingut (estàndards, aspectes legals, ajuts de digitalització, etc.), La experiència d'una de les universitats -la UPF- que participa en aquests dipòsits cooperatius i que alhora disposa del seu propi i la infraestructura tècnica en la qual s'han desenvolupat i evolucionat.

Deficiencia nutricional de yodo en gestantes pertenecientes al distrito sanitario Sierra de Huelva-Andévalo, sur de España

Background. Iodine is an essential trace element implicated in synthesis of thyroid hormones. Iodine requirements vary throughout life. Yhis iodine requirement is increased during pregnancy and breastfeeding. In a previous study carried out by our group in 2008, we detected an iodine-deficient area in the province of Huelva, specially in dictrict Sierra de Huelva-Andévalo by means of neonatal TSH determinations. Objective. To reinforce the iodine supplementation campaign and its impact on their newborns in order to assess nutrition iodine status in 'pregnant women using questionnaire and ioduria determination. Material and methods. This study has been jointly carried out by Congenital Hypothiroidism Unit of the Clinical Biochemistry Department of the Virgen Macarena University Hosplital (Seville) and the Gynecology and Clinical Analysis Unit of the Río Tinto Hospital (Huelva) during two years. We studied 313 pregnant women. All of them filled out a personal questionnaire to know the iodine nutritional status in their area. Ioduria was determined by high-resolution liquid chromatography. Data from pregnant and results of the studied variables were analyzed with SPSS v.13.0. Conclusions. Pregnant women from the sanitary district Sierra de Huelva-Andévalo present a median for ioduria which corresponds to an insufficient iodine intake according to the WHO classification. The questionnaire suggest that this iodine deficiency is consequence of an insufficient iodine intake and a low adherence to the treatment.

Novel (60%) and recurrent (40%) androgen receptor gene mutations in a series of 59 patients with a 46,XY disorder of sex development.

BACKGROUND Androgen receptor (AR) gene mutations are the most frequent cause of 46,XY disorders of sex development (DSD) and are associated with a variety of phenotypes, ranging from phenotypic women [complete androgen insensitivity syndrome (CAIS)] to milder degrees of undervirilization (partial form or PAIS) or men with only infertility (mild form or MAIS). OBJECTIVE The aim of the study was to characterize the contribution of the AR gene to the molecular cause of 46,XY DSD in a series of Spanish patients. SETTING We studied a series of 133 index patients with 46,XY DSD in whom gonads were differentiated as testes, with phenotypes including varying degrees of undervirilization, and in whom the AR gene was the first candidate for a molecular analysis. METHODS The AR gene was sequenced (exons 1 to 8 with intronic flanking regions) in all patients and in family members of 61% of AR-mutated gene patients. RESULTS AR gene mutations were found in 59 individuals (44.4% of index patients), of whom 46 (78%) were CAIS and 13 (22%) PAIS. Fifty-seven different mutations were found: 21.0% located in exon 1, 15.8% in exons 2 and 3, 57.9% in exons 4-8, and 5.3% intronic. Twenty-three mutations (40.4%) had been previously described and 34 (59.6%) were novel. CONCLUSIONS AR gene mutation is the most frequent cause of 46,XY DSD, with a clearly higher frequency in the complete phenotype. Mutations spread along the whole coding sequence, including exon 1. This series shows that 60% of mutations detected during the period 2002-2009 were novel.

CNDOL: A fast and reliable method for the calculation of electronic properties of very large systems. Applications to retinal binding pocket in rhodopsin and gas phase porphine.

Very large molecular systems can be calculated with the so called CNDOL approximate Hamiltonians that have been developed by avoiding oversimplifications and only using a priori parameters and formulas from the simpler NDO methods. A new diagonal monoelectronic term named CNDOL/21 shows great consistency and easier SCF convergence when used together with an appropriate function for charge repulsion energies that is derived from traditional formulas. It is possible to obtain a priori molecular orbitals and electron excitation properties after the configuration interaction of single excited determinants with reliability, maintaining interpretative possibilities even being a simplified Hamiltonian. Tests with some unequivocal gas phase maxima of simple molecules (benzene, furfural, acetaldehyde, hexyl alcohol, methyl amine, 2,5 dimethyl 2,4 hexadiene, and ethyl sulfide) ratify the general quality of this approach in comparison with other methods. The calculation of large systems as porphine in gas phase and a model of the complete retinal binding pocket in rhodopsin with 622 basis functions on 280 atoms at the quantum mechanical level show reliability leading to a resulting first allowed transition in 483 nm, very similar to the known experimental value of 500 nm of "dark state." In this very important case, our model gives a central role in this excitation to a charge transfer from the neighboring Glu(-) counterion to the retinaldehyde polyene chain. Tests with gas phase maxima of some important molecules corroborate the reliability of CNDOL/2 Hamiltonians.

Control de Commelina erecta L. con herbicidas postemergentes con el objetivo de su uso en cultivos de soja transgénica

O presente trabalho teve como objetivo avaliar a eficácia dos herbicidas aplicados em pósemergência em plantas de soja, para o controle de Commelina erecta L. O experimento foi conduzido sob condições de casa-de-vegetação. A aplicação foi realizada quando as plantas encontravam-se no estádio de seis folhas. Foram feitas 6 repetições com os seguintes tratamentos, com as doses em i.a./ha: 1) glyphosate (1494 g), 2) tifensulfuron methyl (6 g), 3) chlorimuron ethyl (10 g), 4) benazolin (300 g), 5) flumiclorac pentil (30 g), 6) bentazon (480 g), 7) lactofen (156 g), 8) fomesafen ( 200 g), 9) oxifluorfen (480 g), 10) imazethapyr (80 g), 11) fluoroglicofen (48 g) e testemunha sem aplicação. Foram feitas avaliações visuais e medições da altura das plantas aos 7 e aos 14 dias e, avaliação de matéria seca aos 28 dias após da aplicação. Os dados avaliados foram analisados através do ANOVA. Todos os tratamentos diferiram significativamente em relação à testemunha, ao nível de 5% de probabilidade (Teste LSD). Os herbicidas glyphosate (100% de mortalidade) e imazethapyr (67% de mortalidade de plantas) diferiram com os demais tratamentos. Chlorimuron ethyl, bentazon e lactofen também mostraram ser eficientes causando reduções maiores de 80% do peso de massa seca das plantas daninhas. Benazolin e flumiclorac pentil foram os de menor eficácia até quando causaram reduções de 50 e 60% de matéria seca da planta daninha.

Isozyme markers and genetic variability in three species of Centrosema (Leguminosae)

Isozyme patterns and their genetic control in three Centrosema species are described. Seven isozymatic systems (aspartate aminotransferase, glucose-6-phosphate isomerase, phosphoglucomutase, anodal peroxidase, malate dehydrogenase, 6-phosphogluconate dehydrogenase, and isocitrate dehydrogenase) were studied in 18 populations and several breeding lines of C. acutifolium, C. brasilianum and C. pubescens, using starch gel electrophoresis techniques. All systems, except glucose-6-phosphate isomerase, are described for the first time in these species. A total of 17 isozyme loci were scored; this represents the largest set of Mendelian loci known up to now in Centrosema species. Isozyme polymorphism and variability within and between populations and species were relatively high and allowed discrimination among species
