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...

Available online 23 July 2018 Author(s): Andrés J. Rascón, Abdelmonaim Azzouz, Evaristo BallesterosAbstractThe presence of polycyclic aromatic hydrocarbons (PAHs) in edible oils is usually due to environmental contamination, manufacturing processes or the nature of the oil. Because oils constitute a very large family of foodstuffs that are ubiquitous in human diet, the presence of PAHs in them...

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...

Pesticide residue in food is of grave concern in recent years. In this paper, a rapid, sensitive, SERS (Surface-enhanced Raman scattering) active reduced-graphene-oxide-gold-nano-star (rGO-NS) nano-composite nanosensor was developed for the detection of acetamiprid (AC) residue in green tea. Different concentrations of AC combined with rGO-NS nano-composite electro-statically, yielded a strong...

Glyphosate is the most widely used herbicide at the moment. It presents a broad spectrum of action, hence its use for many different crops. Regulatory agencies have constantly mentioned the low hazard potential to mammals. However, the International Agency for Research on Cancer concluded in 2015 that glyphosate is “probably carcinogenic to humans.” For this reason, it is...
