The structure and dynamics of the AC114 galaxy cluster revisited

We present a dynamical analysis of the galaxy cluster AC114 based on a catalogue of 524 velocities. Of these, 169 (32%) are newly obtained at ESO (Chile) with the VLT and the VIMOS spectrograph. Data on individual galaxies are presented and the accuracy of the measured velocities is discussed. Dynamical properties of the cluster are derived. We obtain an improved mean redshift value z= 0.31665 +/- 0.0008 and velocity dispersion \sigma= 1893+73-82 \kms. A large velocity dispersion within the core radius and the shape of the infall pattern suggests that this part of the cluster is in a radial phase of relaxation with a very elongated radial filament spanning 12000 \kms. A radial foreground structure is detected within the central 0.5/h Mpc radius, recognizable as a redshift group at the same central redshift value. We analyze the color distribution for this archetype Butcher-Oemler galaxy cluster and identify the separate red and blue galaxy sequences. The latter subset contains 44% of confirmed members of the cluster, reaching magnitudes as faint as R_{f}= 21.1 (1.0 magnitude fainter than previous studies). We derive a mass M_{200}= (4.3 \pm 0.7) x 10^15 Msun/h. In a subsequent paper we will utilize the spectral data presented here to explore the mass-metallicity relation for this intermediate redshift cluster.Comment: 17 pages, 11 figures, 4 tables, accepted for publication in MNRA

Glycogen synthase kinase-3β (GSK-3β) and Nuclear Factor Kappa-B (NF-kB) in childhood acute lymphoblastic leukemia.

Background. Acute lymphocytic leukemia (ALL) is the most common hematologic malignancy in early childhood. In children with acute lymphoblastic leukemia (ALL), the activity of glycogen synthase kinase (GSK-3β) has been associated with changes in the transcriptional activity and expression of nuclear factor kappa beta (NFKB) in the mononuclear cells of bone marrow. Objectives. The aim of the study was to determine the possible role of glycogen synthase kinase 3beta (GSK-3β) and nuclear factor kappa beta (NFKB) as prognostic variables in pediatric patients with ALL. Material and Methods. This was a descriptive, transversal, and observational study. Bone marrow and blood samples were obtained from 30 children with newly-diagnosed ALL, who were seen at the Hematology-Oncology Service, Hospital para el Niño (HPN), Toluca, Mexico, from 2014‒2015. Anthropometric variables, clinical lab results, immunophenotype and cytogenetic abnormalities were registered. GSK-3β was evaluated through immunohistochemistry, and NFKB messenger RNA (mRNA) with real-time polymerase chain reaction (qPCR). The cases of ALL were classified into two groups of risk: high and habitual. Results. Thirty patients were included in this study, with a mean age of 7.1 years (range 2‒13 years). Twenty-one were male and 9 female. Employing the morphological classification, 26 patients had type L1 ALL and the remaining 4 patients had type L2 ALL. Abnormal genes were found in 7 (23.33%) patients, ETV-RUNX1 in 3, followed by TCF3-PBX1 (two), STL1-TAL1 (one), and BCR-ABL1 (one). NFKB relative expression levels, in comparison to the GSK-3β immunohistochemistry results of the bone marrow samples, showed significant differences between positive and negative cases (p = 0.001) and between weak-positive and negative cases (p = 0.002). Conclusions. These results suggest that GSK-3β may be a prognostic biomarker in childhood ALLCiprés Grupo Médic

Multiple Resistance to Glyphosate and 2,4-D in Carduus acanthoides L. from Argentina and Alternative Control Solutions

Carduus acanthoides L. is an invasive species native to Europe and distributed in other parts of the world, including North and South America. In Cordoba, Argentina, control failures of this species have been reported in Roundup Ready (RR) soybean crops where glyphosate and 2,4-D have frequently been applied, although there are no confirmed reports worldwide of resistance to glyphosate and 2,4-D in this species. Dose–response tests showed multiple-resistance to both active principles. The resistant population (R) had LD50 values of 1854.27 and 1577.18 g ae ha−1 (grams of acid equivalent per hectare), while the susceptible (S) population had LD50 values of 195.56 and 111.78 g ae ha−1 for glyphosate and 2,4-D, respectively. Low accumulations of shikimic acid (glyphosate) and ethylene (2,4-D) at different doses in the R population compared to the S population support the results observed in the dose–response curves. No significant differences in leaf retention were observed for glyphosate and 2,4-D in the R and S populations. However, the use of adjuvants increased the retention capacity of herbicides in both populations. Ten alternative herbicides with seven different action mechanisms (MOAs) were evaluated and the most effective active principles were dicamba, bromoxynil, atrazine, tembotrione, flazasulfuron, glufosinate, and paraquat. These findings are the first evidence of glyphosate and 2,4 D resistance in C. acanthoides

Do food quality schemes and net price premiums go together?

This article addresses the issue of the profitability of Food Quality Scheme (FQS) products as compared to reference products, which are defined as analogous products without quality label. We approach this question by taking into account the level of the value chain (upstream, processing, and downstream), the sector (vegetal, animal, seafood) and the type of FQS (PGI, PDO, Organic). We collected original data for several products produced in selected European countries, as well as in Thailand and Vietnam. Comparisons depending on value chain level, sector and FQS are possible by using two comparable indicators: price premium and net price premium (including cost differential). The following principal conclusions were reached: 1) Price is higher for FQS products than for the reference products, regardless of the production level, the type of FQS or the sector; 2) Price premiums generated by FQS do not differ along the value chain, nor between sectors (vegetal, animal or seafood/fish); 3) Price premium for organic products is significantly higher than for PGI products, and this conclusion holds at upstream and processing levels, taking into account the costs directly related to production; 4) All organic products and almost all PDO and PGI products analysed benefit from a positive quality rent; 5) At upstream level and processing level, the relative weight of intermediate consumption in the cost structure is lower for organic products than for reference products.Objectius de Desenvolupament Sostenible::12 - Producció i Consum ResponsablesPostprint (published version

Height, Weight and Body Mass Index by Age and Sex in Children Aged 4 to 6 Years in Merida, Mexico, as Compared to International References After Normalization with LMS

A cross-sectional study was done in 2006–2007 of 458 children (218 boys and 240 girls) aged 4 to 6 years (range 4.00 to 6.99 years) in Merida, Mexico. Height (cm) and body weight (kg) were measured to estimate growth; body mass index (BMI, kg/m2) was calculated to evaluate nutritional status. Results showed signifi cant sex difference with respect to height, weight, and BMI. Increment of height and weight with age was observed. However, age difference in BMI was not consistent. Nutritional status was evaluated using International Obesity Task Force (IOTF) classifi cation and BMI cut-off values showed notable rates of overweight (boys 14.41% and girls 17.75%) and obesity (boys 12.43% and girls 7.21%). Anthropometric data of height, weight, and BMI were normalized using LMS methodology and were compared with World Health Organization (WHO) growth reference data. Again, increment of height and weight with age was observed although those were lower in the present study for boys and girls than the corresponding WHO growth reference data. In contrast, mean BMI by age in the present results exceeded WHO reference data, especially above the 85th percentile. Assessment of nutritional status with reference to IOTF and WHO revealed similar trends

Sustainability Performance of Certified and Non-certified Food: Social and Economic History

Abstract The dataset Sustainability performance of certified and non-certified food (https://www.doi.org/10.15454/OP51SJ) contains 25 indicators of economic, environmental, and social performance, estimated for 27 certified food value chains and their 27 conventional reference products. The indicators are estimated at different levels of the value chain: farm level, processing level, and retail level. It also contains the raw data based on which the indicators are estimated, its source, and the completed spreadsheet calculators for the following indicators: carbon footprint and food miles. This article describes the common method and indicators used to collect data for the twenty-seven certified products and their conventional counterparts. It presents the assumptions and choices, the process of data collection, and the indicator estimation methods designed to assess the three sustainability dimensions within a reasonable time constraint. That is: three person-months for each food quality scheme and its non-certified reference product. Several prioritisations were set regarding data collection (indicator, variable, value chain level) together with a level of representativeness specific to each variable and product type (country and sector). Technical details on how relatively common variables (e.g., number of animals per hectare) are combined into indicators (e.g., carbon footprint) are provided in the full documentation of the dataset.Publishe
