Application of Metabolomics in the Study of Natural Products

LC–MS-based metabolomics could have a major impact in the study of natural products, especially in its metabolism, toxicity and activity. This review highlights recent applications of metabolomics approach in the study of metabolites and toxicity of natural products, and the understanding of their effects on various diseases. Metabolomics has been employed to study the in vitro...

First report of Litylenchus coprosma on Coprosma robusta

Litylenchus coprosma is reported for the first time from Coprosma robusta at two locations in Wellington, New Zealand. Nematodes were isolated from the leaves with angular yellow patches limited by veins and identified as L. coprosma based on morphology and sequence analysis of the SSU and LSU regions of rDNA.

Energy efficiency of compressed spectrum sensing in wideband cognitive radio networks

In cognitive radio networks, wideband spectrum sensing (WSS) has been advocated as an effective approach to increase the spectrum access opportunity of the secondary users. On the other hand, because of the increase of sampling rate and sensing time duration cost by the analog-to-digital converter (ADC), energy saving has been a significant problem for WSS. In this paper, taking...

Cardiotoxicity evaluation using human embryonic stem cells and induced pluripotent stem cell-derived cardiomyocytes

Background Cardiotoxicity remains an important concern in drug discovery. Human pluripotent stem cell-derived cardiomyocytes (hPSC-CMs) have become an attractive platform to evaluate cardiotoxicity. However, the consistency between human embryonic stem cell-derived cardiomyocytes (hESC-CMs) and human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) in prediction...

Mapping the landscape of metabolic goals of a cell

Genome-scale flux balance models of metabolism provide testable predictions of all metabolic rates in an organism, by assuming that the cell is optimizing a metabolic goal known as the objective function. We introduce an efficient inverse flux balance analysis (invFBA) approach, based on linear programming duality, to characterize the space of possible objective functions...

Transcriptomic and physiological analysis of common duckweed Lemna minor responses to NH 4 + toxicity

Background Plants can suffer ammonium (NH 4 + ) toxicity, particularly when NH 4 + is supplied as the sole nitrogen source. However, our knowledge about the underlying mechanisms of NH 4 + toxicity is still largely unknown. Lemna minor, a model duckweed species, can grow well in high NH 4 + environment but to some extent can also suffer toxic effects. The transcriptomic and...

Subsurface Geobody Imaging Using CMY Color Blending with Seismic Attributes

Recently, ideas of color blending have brought the enlightenment for subsurface geobody imaging in petroleum engineering. In this paper, we present this approach of CMY color blending and its application in subsurface geobody characterization by using seismic attributes data. The first step is to calculate three types of seismic attributes based on the Hilbert transform algorithm...
