BACKGROUND In April, 2013, a Suzhou Hospital reported a nitrite intoxication patient in coma as well as 2 family members with the similar symptom 5 days ahead. We investigated the event to identify the cause, source and possible pollution ways of the contamination. METHODS We defined case as any person living in YSHY community who has cyanosis and with at least one of the following symptoms: ...

Since haematological variables can be used to assess the health state in cultured fish, a haematological characterization of clinically healthy Oreochromis aureus was done to establish the reference indices of this species. Fish were subjected to different stressed conditions (bacterial infection, nitrite intoxication, malachite green overdose) to study the changes in the haematological indices...

Pickles are popular in China and exhibits health-promoting effects. However, nitrite produced during fermentation adversely affects health due to formation of methemoglobin and conversion to carcinogenic nitrosamine. Fruiting bodies of the mushroom Boletus edulis were capable of inhibiting nitrite production during pickle fermentation. A 90-kDa nitrite reductase (NiR), demonstrating peptide seq...

The purpose of this study was to examine the prevalence, patterns, and predictors of nitrite inhalant use in antisocial adolescents. Face-to-face interviews were conducted with 723 Missouri youth (M age = 15.5, SD = 1.2) in residential care for antisocial behavior. The lifetime prevalence of nitrite inhalant use was 1.7% (1.3% for boys; 4.3% for girls, p = .06), a figure somewhat higher than co...

Methylmercury (MeHg) is one of the most toxic mercury species, which can cause many systemic damages, but little is known about its effect in the salivary glands. This study aimed to analyze the mercury levels, oxidative stress, and proteomic profile in parotid, submandibular, and sublingual salivary glands of rats, after chronic MeHg intoxication. Two groups of twenty male Wistar rats (90 days...

A novel probe based on the fluorescence off-on strategy was prepared to optically detect hydrogen sulfide (H2S) via an excited state intramolecular proton transfer (ESIPT) mechanism. The probe shows high sensitivity and excellent selectivity to H2S. It also displays a large Stokes shift ( approximately 140nm) and a remarkable quantum yield enhancement (capital EF, Cyrillic=0.412) after interact...

Binge drinking is common among adolescents, and this type of ethanol exposure may lead to long-term nervous system damage. In the current study, we evaluated motor performance and tissue alterations in the cerebral cortex of rats subjected to intermittent intoxication with ethanol from adolescence to adulthood. Adolescent male Wistar rats (35 days old) were treated with distilled water or ethan...
