A simple analytical method combining solvent extraction and liquid chromatography-high-resolution mass spectrometry (LC-HRMS) was developed for the analysis of pesticide residues in rice bran protein powder. Owning to the high accuracy of HRMS in determination of mass to charge ratio (m/z), a suspect screen of pesticide residues was performed by LC-HRMS prior to...

In this work, surface-enhanced Raman spectroscopy (SERS) was used with silver colloid substrate for rapid detection of omethoate (an organophosphate pesticide) in standard solution and peach extract. The findings demonstrated that the characteristic wavenumber of the pesticide could be precisely identified using the SERS method. The calibration curve was plotted between...

A method was developed for the analysis of four polycyclic aromatic hydrocarbons regulated in the European Union, namely, benzo[a]anthracene, chrysene, benzo[b]fluoranthene, and benzo[a]pyrene in edible oils. Multi-walled carbon nanotubes were applied for dispersive solid-phase extraction of analytes from the oils after dilution with n-hexane followed by elution of analytes...

The detection of polycyclic aromatic hydrocarbons (PAHs) and their metabolites in food and in agricultural sources is an important research objective due to the PAHs’ known persistence, carcinogenicity, and toxicity. PAHs have been found in the milk of lactating cows and in the leaves and stems of plants grown in PAH-contaminated areas, thereby making their way into both cow...

Kanamycin (Kan) and tobramycin (Tob) are widely found in many foods of animal origin, including milk. More rapid, simple, and sensitive methods are urgently needed to monitor antibiotic residues in milk. An enhanced direct competitive enzyme-linked immunosorbent assay (dcELISA) based on gold nanoparticles (AuNPs)/horse radish peroxidase-Kan (HRP-Kan) was developed. A...

The huntingtin N17 domain is a modulator of mutant huntingtin toxicity and is hypophosphorylated in Huntington’s disease (HD). We conducted high-content analysis to find compounds that could restore N17 phosphorylation. One lead compound from this screen was N6-furfuryladenine (N6FFA). N6FFA was protective in HD model neurons, and N6FFA treatment of...

Enterotoxigenic Escherichia coli (ETEC) causes diarrheal illness in infants in the developing world and travelers to countries where the disease is endemic, including military personnel. ETEC infection of the host involves colonization of the small intestinal epithelium and toxin secretion, leading to watery diarrhea. There is currently no vaccine licensed to prevent ETEC infection. CFA/I is one...
