Environmental Toxicology, EarlyView.ABSTRACT Resazurin is a cell viability phenoxazine dye widely employed for bacterial monitoring, as its colorimetric and fluorometric conversion reflects microbial metabolic activity. In this work, we demonstrate that graphene oxide (GO), a two‐dimensional nanomaterial with high surface reactivity, markedly accelerates the reduction of resazurin in the

Journal of Chemistry, 2013 The reactions of some metal ions of the third group (M(III)) with azo dyes were studied. Attention was focused on azo dyes with two hydroxy groups in ortho-positions to azo group: eriochrome red B (ERB), eriochrome black T (EBT), eriochrome blue SE (EBSE)

Contact Dermatitis, EarlyView.Among 2678 female hairdressers and 6244 female consumers with contact dermatitis suspected to be related to use of hair cosmetics, including dyes, patch tested in the IVDK between 1995 and 2020, diverging contact allergy trends were observed. In the case of toluene‐2,5‐diamine (PTD) shown in the figure, sensitization was at a stable, high level in ...

The plasticisation model of dye diffusion: Part 6
Coloration Technology, EarlyView.Abstract Previously published data reported for the temperature dependency of the exhaustion of a mordant dye and acid dye, as well as both the exhaustion and fixation of a reactive dye and adsorption of a direct dye, on three different types of wool substrate, over a diverse range of dyeing temperatures and conditions, were re‐evaluated using the ...

Süleyman Demirel Üniversitesi Fen-Edebiyat Fakültesi Fen Dergisi, 2013 In this study, several derivatives of amines were diazotized and coupled with 3-aminocrotonitrile to give 2-arylhydrazon-3-ketiminocrotononitrile. The synthesized components were then refluxed with hydrazine hydrate in ethanol to give a series of dyes 5 ...

The FEBS Journal, EarlyView.Nitrate from food is first converted to nitrite by oral bacteria and then further processed in the intestine. The gut microbiota reduces nitrate and nitrite to ammonia or nitric oxide, preventing the formation of carcinogenic nitrosamines. Our analysis highlights Escherichia coli as a key player in this detoxification process, supported by other ...

Case Studies in Chemical and Environmental EngineeringAzo dyes comprise xenobiotic compounds characterized by the azo group (-NN-). The textile industry primarily consumes this type of dye, discharging significant amounts of textile wastewater with high pollution levels and temperature, necessitating ...

Experimental Physiology, EarlyView.Abstract Ageing is a risk factor for cardiovascular and neurodegenerative diseases. The myogenic response in resistance arteries is responsible for basal (myogenic) tone and blood flow autoregulation. G‐protein‐coupled receptors and G12/RhoA/Rho kinase are implicated in myogenic tone (MT), and we aimed to clarify their role in pressure sensing and ...
