“…Pasquet et al 2013 dyed polyester fabric with o-and p-vanillin in the presence of two disperse dyes (C.I Disperse Blue 56, and C.I Disperse Blue 79) with ethanol as cosolvent. The study confirmed that color strength of the polyester dyed with these auxiliaries was good, mainly when o-vanillin was used [7].…”

The aim of the study was to dye polyester fabric with a low molecular weight anthraquinone type disperse dye (C.I. Disperse Blue 56), with n-butylacetate as co-solvent in the microemulsion system and the presence of two bio-based auxiliaries (ortho-vanillin and coumarin), at temperatures lower than 100℃. In order to investigate the influence of temperature and auxiliaries on the kinetic dyeing process, the energy of the activation was determined by the kinetic rates constants. The activated entropy values were obtained by the theory of absolute rates of dyeing and diffusion of the activated state of the dye for the disorder state of the dyeing system. Higher activated energies were found, as well as higher activated entropy, meaning higher dye absorption, for polyester samples dyed with ortho-vanillin/n-butylacetate compared with polyester samples dyed with coumarin/n-butylacetate. Color strength values of the polyester fabric dyed using the proposed microemulsion dyeing system at low temperature (95℃) were similar to polyester fabric dyed with a conventional dyeing system at high temperature (135℃). Regarding color fastness to washing and ironing, it was found that the use of the auxiliaries did not significantly modify the fastness values of the dyed samples.

“…To put it simply, mordants are widely used for the pretreatment of different natural and synthetic fibres, including cotton , flax , silk , wool , polyester , nylon , and acrylic . Bulut and Akar used citric acid and sodium carbonate as biomordants for dyeing of some plant wastes on woollen yarn and cationised cotton fabric.…”

Acid and disperse dyes are two well‐known synthetic materials that are primarily used for dyeing of nylon 6 fibres. Despite their good performance, several negative impacts on the environment, including air and water pollution, are major concerns to researchers. An alternative ecofriendly approach to the dyeing of nylon 6 is the use of natural dyes, given their abundant natural sources, biocompatibility, biodegradability, non‐toxicity, non‐allergic responses, and non‐carcinogenic effects on human life. Based on these advantages, we extracted polyphenolic dyes from henna leaves, pomegranate rind, and Pterocarya fraxinifolia leaves and studied the dyeability on nylon 6 fabric using three compounds of aluminium sulfate, tannic acid, and tin chloride as toxic and non‐toxic mordants before dyeing. Fourier transform infrared spectra of the nylon 6 fabric confirmed the coordination complexes and π–π bonding between the mordants and the dyes. Colorimetric and fastness results showed that the mordants increased the colour strength and improved the fastness properties of the fibres. Our results suggest that tin chloride and aluminium sulfate as metal mordants can be successfully replaced with tannic acid as a biomordant in the natural dyeing of nylon 6. Also, cost assay showed that dyeing of nylon 6 with extracted natural dyes from waste leaves could be a sustainable and economical substitute for synthetic dyeing.

“…In the present study, OV was used as the TLR2 inhibitor to block TLR2-mediated inflammation in LPS-induced AKI mice for a number of reasons. OV is an organic compound present in many plants and has been demonstrated to exhibit no cytotoxicity in numerous studies so far, making this inhibitor a suitable candidate with great potential for drug development (21,39). In particular, OV has been proven to specifically inhibit mouse and human TLR2 signaling, which can facilitate the translation of research from animal to a more clinical setting (21).…”

Treatment with toll‑like receptor 2 inhibitor ortho‑vanillin alleviates lipopolysaccharide‑induced acute kidney injury in mice

et al. 2019

Reducing inflammation is a promising approach for the prevention and treatment of septic acute kidney injury (AKI), since AKI is characterized by excessive inflammation in the kidney. Previous studies have demonstrated that toll-like receptor 2 (TLR2) is overstimulated, which promotes inflammation by activating the NF-κB signaling pathway, in a lipopolysaccharide (LPS)-induced model of AKI mice. For the present study, it was hypothesized that TLR2 inhibition could reduce inflammation and consequently prevent septic AKI. Therefore, the potential renal protective effects of ortho-vanillin (OV), an inhibitor of TLR2, were investigated in the present study in vitro and in vivo. In vitro treatment with OV on LPS-stimulated mouse podocyte cell line MPC5 did not affect TLR2 expression but interrupted the interaction between TLR2 and its downstream adaptor MyD88, resulting in the reduction of inflammatory cytokines IL-6 and TNF-α expression. In vivo OV treatment in an LPS-challenged mouse model effectively alleviated LPS-induced kidney injury as indicated by histology analysis and the significantly reduced blood urea nitrogen and serum creatinine levels. Additionally, inflammatory cytokines TNF-α, IL-6 and IL-1β expression were also significantly reduced in mice with OV treatment. Signaling pathway analysis further demonstrated that OV treatment did not affect the expression of TLR2 and p65 but suppressed p65 phosphorylation. Taken together, data from the present study demonstrated that OV was effective in protecting renal function against LPS-induced AKI through the inhibition of TLR2/NF-κB signaling and subsequent inflammatory cytokine production. These findings indicated that OV or targeting TLR2 signaling in general, represents a novel therapeutic approach for use in the prevention and treatment of AKI.
