Quantitative real time PCR, recently developed in molecular biology, is applied this paper to quantify the white spot syndrome virus (WSSV) infected shrimp tissue. The WSSV content moribund of all species tested ( Penaeus stylirostris, P. monodon, vannamei ) ranged from 2.0 × 10 4 9.0 copies μg –1 total DNA n =26). In whole post‐larvae, 4.3 9 were detected which equivalent 5.7 g post‐larvae. comparison between different tissues showed that muscle and hepatopancreas contained times less than...
Abstract The frequency/magnitude distribution of earthquakes can be approximated by an exponential law whose exponent (the so‐called ) is routinely used for probabilistic seismic hazard assessment. commonly measured using Aki's maximum likelihood estimation, although biases arise from the choice completeness magnitude (i.e., below which no longer valid). In this work, we introduce b‐Bayesian method, where full frequency‐magnitude modeled product and a detection law. characterized two...
Since 1992, white spot syndrome virus (WSSV) and yellow head (YHV) have caused mortalities in cultured shrimp throughout Asia. By 1995, WSSV was detected Texas South Carolina, the has also been recently reported Central America (Nicaragua, Honduras, Guatemala, Panama, Colombia, Peru, Ecuador). The importation of live infected is principal mechanism by which exotic viruses may be introduced to new geographic regions. However, another probable via commodity from regions where pathogens are...
Untargeted metabolomics may reveal preventive targets in cognitive aging, including within the food metabolome.
Breast cancer is a major cause of death in occidental women. The role metabolism breast etiology remains unclear. Metabolomics may help to elucidate novel biological pathways and identify new biomarkers predict long before symptoms appear. aim this study was investigate whether untargeted metabolomic signatures from blood draws healthy women could contribute better understand the long-term risk developing cancer.A nested case-control conducted within SU.VI.MAX prospective cohort (13 years...
Abstract There is scarce information on whether inhibition of rumen methanogenesis induces metabolic changes the host ruminant. Understanding these possible important for acceptance methane-reducing practices by producers. In this study we explored in plasma profiles associated with reduction methane emissions. Plasma samples were collected from lactating primiparous Holstein cows fed same diet (Treated, n = 12) or without (Control, 13) an anti-methanogenic feed additive six weeks. Daily...
Prediction of retention times (RTs) is increasingly considered in untargeted metabolomics to complement MS/MS matching for annotation unidentified peaks. We tested the performance PredRet (http://predret.org/) predict RTs plant food bioactive metabolites a data sharing initiative containing entry sets 29-103 compounds (totalling 467 compounds, >30 families) across 24 chromatographic systems (CSs). Between 27 and 667 predictions were obtained with median prediction error 0.03-0.76 min...
Abstract The metabolic pathway involved in the biotransformation of herbicide mesotrione by bacterial strain Bacillus sp. 3B6 was investigated a reliable liquid chromatography/electrospray ionization quadrupole time‐of‐flight mass spectrometry (LC/ESI‐QTOF‐MS) method. LC/ESI‐MS method, both positive and negative mode, with assistance MS 2 fragments isotopic pattern analyses, allowed us to identify five metabolites. This work constitutes first complete monitoring degradation kinetics. Among...
Diet has been recognized as a modifiable risk factor for breast cancer. Highlighting predictive diet-related biomarkers would be of great public health relevance to identify at-risk subjects. The aim this exploratory study was select metabolites discriminating women at higher cancer using untargeted metabolomics.
This study explored plasma biomarkers and metabolic pathways underlying feed efficiency measured as residual intake ( RFI ) in Charolais heifers. A total of 48 extreme individuals (High-RFI, n = 24; Low-RFI, 24) were selected from a population 142 heifers for classical metabolite hormone quantification metabolomic profiling through untargeted LC-MS. Most efficient (Low-RFI) had greater (P 0.03) concentrations IGF-1 tended to have 0.06) lower back fat depth compared least However, no changes...
Long-term treatment-related toxicities, such as neurologic and metabolic are major issues in breast cancer. We investigated the interest of metabolomic profiling to predict toxicities.
Bioactive compounds present in plant-based foods, and their metabolites derived from gut microbiota endogenous metabolism, represent thousands of chemical structures potential interest for human nutrition health. State-of-the-art analytical methodologies, including untargeted metabolomics based on high-resolution mass spectrometry, are required the profiling these complex matrices, plant food materials biofluids. The aim this project was to compare coverage methods independently developed...
