A quantitative colorimetric sensing strategy utilizing cysteamine modified gold nanoparticles (CA-AuNPs) as reporters for Hg(2+) and melamine was demonstrated. Cysteamine is a cheap and commercially available aminothiol and is also the most important chelating ligand in coordination chemistry possessing the ability to coordinate to Hg(2+) and melamine. The terminal thiol group in cysteamine is ...

Two young dogs belonging to the same kennel placed nearby Treviso (north-eastern Italy) died at the end of 2008 with clinical signs of renal failure. They were subjected to necropsy and were evaluated for histopathological and toxicological changes. Both the animals had same clinical signs and laboratory evidence of uremia. Post mortem investigations revealed severe nephrotoxicosis, associated ...

The contamination of melamine was evaluated in 69 infants along with follow up formula samples collected from the market for the first time in Iran using HPLC method. Since there are no previous data concerning the contamination level of melamine in all brands of infant formula samples consumed using the HPLC method in Iran, this study is the first investigation in this regard. Our results show...

It is currently believed that melamine ingestion can lead to insoluble crystals in an animal's urinary system with subsequent physical obstruction or bladder carcinoma. However, whether melamine can cause injury of other tissues and organs in humans is yet unknown. In this study, we encountered 3 affected children with liver lesions, 2 males and 1 female, and detailed their clinical characteriz...

Based on melamine binding-triggered triplex formation and subsequent activation of Mg(2+)-dependent DNAzymes, a novel strategy for DNAzyme regulation was proposed and developed for melamine recognition.

In this work, a molecularly imprinted polymer (MIP) coated stir bar was prepared using a self-designed polytetrafluoroethylene (PTFE) mold and in situ polymerization, with cyromazine as the dummy template for the target melamine. The prepared MIP coated stir bar presented a uniform and porous surface as well as good chemical stability and selectivity for melamine. Based on it, a method of MIP c...

The melamine contaminated milk powder contamination scandal occurred in China in 2008. Its main consequences so far have been urinary stone formation in children with associated renal damage and increased child mortality. Eight years have passed, but food safety issues still remain of concern in the daily lives of millions of Chinese. Vigilance is required to ensure no recurrence of such food s...

Since the melamine-contamination event happened in September 2008, there have been lots of studies about melamine toxicity, but very limited studies focused on central nervous system (CNS). In the present study, we investigated the effects of melamine (5x10(-4), 5x10(-5) and 5x10(-6)g/ml) on voltage-gated sodium channels (VGSCs) in hippocampal CA1 neurons using whole-cell patch-clamp recordings...

Melamine is an adulterant commonly found in milk, as it can increase the nitrogen content. Therefore, its apparent protein content, resulting in a better market price. Melamine adulteration can be fatal, as was highlighted in 2008 when six infants died due to melamine adulteration in milk powder and thousands were sickened in China. Consequently, there have been stricter regulations globally an...

Abstract Bamboo tableware became popular as ecofriendly material. However, industrial products made of bamboo-melamine–formaldehyde resin material are not biodegradable. In addition, harmful compounds were detected if such consumer articles used with hot drinks or food, and risk assessment found that maximum daily dosages melamine formaldehyde exceeded. High-performance thin-layer chromatograph...
