Bornyl gallate (BG) is a potential drug candidate synthesized by the reaction of two natural products, gallic acid and borneol. Previous studies have strongly suggested that BG is worthy of further investigation due to antioxidant, antiatherosclerosis activities, and obvious activity of stimulating intersegmental vessel growth in zebrafish. This work was designed to elucidate the metabolic prof...

On-plate enrichment of phosphopeptide digests followed by MALDI-MS is attractive for analyzing small quantities of phosphoproteins because it involves minimal sample handling and reduces sample loss. This work describes a method for modification of Si wafers, which serve as MALDI plates, with 250 microm-diameter microspots of phosphopeptide-binding polymer brushes enclosed by a hydrophobic poly...

The phytoconstituents of the essential oil isolated by hydrodistillation and solvent extracts (PE, BZ, DCM, EtOAc EtOH) mature rhizomes turmeric (Curcuma pseudomontana) were analyzed GC–MS. major constituents identified in Benzofuran (6.93%), γ-Curcumene (11.18%), β-Elemenone (22.14%), Germacrone (15.15%), Phenol, 2-Methyl-5-(1,2,2-trimethylcyclopentyl)- (29.58%), Germacrene (8.78%), Italicene ...

This paper aims at analyzing nonlinear dependence between fractionally integrated, chaotic precious metal and oil prices volatilities. With this respect, the Markov regime-switching integrated asymmetric power versions of generalized autoregressive conditional volatility copula (MS-FIAPGARCH-copula) method are further extended to multi-layer perceptron (MLP)-based neural networks (MS-FIAPGARCH-...

Aspects are a recent modularization paradigm that supports the capturing of concerns that usually crosscut the modularization structure of software systems. However, no support is given for representing, capturing, analyzing and tracing how global qualities of the software system, such as performance, maintainability, or extensibility, are addressed during the design and composition of modules ...

Two multiresidue methods were developed to determine pesticides in air collected in California. Pesticides were trapped using XAD-4 resin and extracted with ethyl acetate. Based on an analytical method from the University of California Davis Trace Analytical Laboratory, pesticides were detected by analyzing the extract by gas chromatography-mass spectrometry (GC-MS) to determine chlorothalonil,...

Comprehensive understanding of the roles and functions of lipids in cellular physiology and pathology requires unambiguous identification and accurate quantification of individual lipid molecular species. However, the enormous structural diversity of lipids (e.g., >37,000 lipid molecules cataloged in the LIPID MAPS database) presents a significant challenge in the high-throughput analysis of li...

The objectives of this study were to evaluate and validate analytical methods for analysis of persistent organic pollutants (POP) in house dust and soil and to obtain concentration profiles for the target POP in house dust and soil samples from the homes of 13 lowincome families. The analytical method for determining p-pentylphenol, poctylphenol, nonylphenols, and bisphenol-A consisted of seque...
