Search for signature inversion in the pi i(13/2) circle times upsilon i1(3/2) bands in Au-182,Au-184,Au-186

Search for low-spin signature inversion in the pi i(13/2) circle times nu i(13/2) bands in odd-odd Au-182,Au-184,Au-186 has been conducted through the standard in-beam gamma-spectroscopy techniques. The experiments for Au-182 and 186Au have been performed in the Japan Atomic Energy Agency (JAEA) via the Sm-152(Cl-35,5n)Au-182 and Yb-172(F-19,5n)Au-186 reactions, respectively. A study of Au-184 has been made using a multi-detector array GASP in LNL, Italy, via the Tb-159(Si-29,4n)Au-184 reaction. The pi i(13/2) circle times nu i(13/2) bands in these three nuclei have been identified and extended up to high-spin states. In particular, the inter-band connection between the pi i(13/2) nu i(13/2) band and the ground-state band in 184 Au has been established, leading to a firm spin-and-parity assignment for the pi i(13/2) circle times nu i(13/2) band. The low-spin signature inversion is found in the pi i(13/2) circle times nu i(13/2) bands in Au-182,Au-184,Au-186 according to our spin-assignment and the signature crossing observed at high-spin states.

The first molluscan TCTP in Venerupis philippinarum: Molecular cloning and expression analysis

Translationally controlled tumor protein (TCTP) is one of the abundant and ubiquitously expressed proteins in metazoans In the present study, the first molluscan TCTP (denoted as VpTCTP) was identified from Venerupis philippinarum haemocytes by EST and RACE approaches The full-length cDNA of VpTCTP consisted of 1148 nucleotides with an open-reading frame of 555 bp encoding 184 amino acids The deduced amino acid sequence of VpTCTP shared high similarity with TCTPs from other species, indicating that VpTCTP should be a new member of TCTP family Several highly conserved motifs, including 5'terminal ologopyrimidine (5'TOP) starting sequence and rich AU and AUUT elements in 3'UTR, were also identified in VpTCTP The tissue and temporal expression of VpTCTP after Vi boo anguillarum challenge was recorded by quantitative real-time RT-PCR. VpTCTP transcript could be detected in all examined tissues with the highest expression level in haemocytes and the lowest in hepatopancreas Concerning the time-course expression in haemocytes, the relative expression of VpTCTP mRNA was down-regulated sharply from 6 h to 12 h post-infection. Then, the expression level was obviously up-regulated and reached 3.4-fold to that in the control group at 48 h post challenge As time progressed, the expression of VpTCTP recovered to the original level at 96 h. All these results indicated that VpTCTP was an acute-phase protein involved in the Immune response of V philippinarum (C) 2010 Elsevier Ltd. All rights reserved.

Gas hydrate occurrence on the continental slope of the northern South China Sea

High-resolution multi-channel seismic data and geological samples were collected during two research cruises of the R/V FENDOU 4 in 1999 and 2000. Studies on these data and samples together with results from sites 1143-1145 and 1148 of ODP Leg 184 suggest that the geological structure on the continental slope of the northern South China Sea is favorable for the formation of gas hydrates. Bottom simulating reflectors (BSRs) and geochemical anomalies which indicate the existence of gas hydrates have been recognized in sediments of the Xisha Trough, the Dongsha Rise and the accretionary wedge of the Manila subduction zone. These gas hydrates are generated by two different mechanisms depending on the tectonic regime and the seismic and geochemical characteristics. The first applies to the passive continental margin of the nor-them South China Sea on the Dongsha Rise and in the Xisha Trough. The gas hydrates are associated with diapiric structures, active faults, slumps and gravity flows as well as high Late Cenozoic sedimentation rates. Their seismic expression includes BSRs, seismic blanking zones and velocity anomalies. The second mechanism is operative on the active continental margin along the Manila subduction zone, especially in the accretionary wedge. Here, gas hydrate occurrence is marked by widespread BSRs and acoustic 'pull-down' possibly related to the existence of free gas in the sediments beneath the BSR. The thickness of the seismic blanking zones averages 250 m, suggesting that the stable gas hydrate zone has about the same thickness. (c) 2005 Elsevier Ltd. All rights reserved.

Development of the East Asian summer monsoon: Evidence from the sediment record in the South China Sea since 8.5 Ma

128 samples from Ocean Drilling Program (ODP) Site 1143 in the southern South China Sea were analyzed for grain size, clay minerals, biogenic opal content and quartz in order to reconstruct changes in East Asian monsoon climate since 8.5 Ma. An abrupt change of terrigenous mass accumulation rate (MAR), clay mineral assemblage, median grain size and biogenic opal MAR about 5.2 Ma suggests that between 8.5-5.2 Ma the source of terrigenous sediment was mainly in the region of surface uplift and basaltic volcanism in southern Vietnam. A simple model of East Asian summer monsoon evolution was based on the clay/feldspar ratio, kaolinite/chlorite ratio and biogenic opal MAR. The summer monsoon has two periods of maximum strength at 8.5-7.6 Ma and 7.1-6.2 Ma. Subsequently, there was a relatively stable period at 6.2-3.5 Ma, continued intensification about 3.5-2.5 Ma, and gradually weakening after 2.5 Ma. Since I Ma the monsoon has intensified, with remarkable high-frequency and amplitude variability. Simultaneous increase in sedimentation rates at ODP Sites 1143, 1146 and 1148, as well as in MAR of terrigenous materials, quartz, feldspar and clay minerals at ODP Site 1143 at 3.5-2.5 Ma, may be the erosional response to both global climatic deterioration and the strengthening of the East Asian summer monsoon after about 3-4 Ma.

Mutation altering the miR-184 seed region causes keratoconus with cataract

MicroRNAs (miRNAs) bind to complementary sequences within the 3? untranslated region (UTR) of mRNAs from hundreds of target genes, leading either to mRNA degradation or suppression of translation. We found that a mutation in the seed region of miR-184 (MIR184) is responsible for familial severe keratoconus combined with early-onset anterior polar cataract, by deep sequencing of a linkage region known to contain the mutation. The mutant form fails to compete with miR-205 (MIR205) for overlapping target sites on the 3? UTRs of INPPL1 and ITGB4. Although these target genes and miR-205 are expressed widely, the phenotype is restricted to the cornea and lens because of the very high expression of miR-184 in these tissues. Our finding highlights the tissue-specificity of a gene network regulated by a miRNA. Awareness of the important function of miRNAs may aid identification of susceptibility genes and new therapeutic targets for treatment of both rare and common diseases.

Desenlaces maternos y fetales en el manejo expectante de la preeclampsia lejos del término

Introducción La preeclampsia hace parte del espectro de los trastornos hipertensivos asociados al embarazo y es causa de alta morbimortalidad materna. La edad gestacional ha sido relacionada con la presentación más severa de esta cuando ocurren lejanas al término. Hoy en día existe la posibilidad de proporcionar manejo expectante en estos casos en unidades de cuidado obstétrico especializadas, con el fin de disminuir el riesgo de morbimortalidad asociada a la prematurez extrema. Metodología Se realizó un estudio de corte transversal que incluyó pacientes con preeclampsia lejos del término entre las 24 y 34 semanas que recibieron manejo expectante entre 2009 y 2012 en la Unidad de Cuidado Intensivo Obstétrico de la Clínica Colsubsidio Orquídeas. Resultados Se incluyeron 121 pacientes con preeclampsia lejos del término, quienes recibieron manejo expectante. La edad promedio fue 29.8, el promedio de días de manejo expectante fue 4 días, con una mediana de tres días. La edad gestacional de ingreso fue 30 1/7 semanas y la edad promedio de terminación 30 5/7 semanas. El 88.4% recibieron esquema de maduración completo. El 81.6% presentaron preeclampsia severa. El desenlace materno más frecuente fue Síndrome Hellp (37%) y el desenlace fetal fue restricción de crecimiento intrauterino (29%). Discusión Se debe considerar el manejo expectante en toda paciente con preeclampsia previa a la semana 34 para manejo antenatal con corticoesteroides, el cual demostró ser un factor protector para muerte perinatal temprana. No se encontraron diferencias significativas entre la aparición de complicaciones y la cantidad de días de manejo expectante.
