Synthesis of azo pyridone dyes [PDF]

Hemijska Industrija, 2011
Over 50% of all colorants which are used nowdays are azo dyes and pigments, and among them arylazo pyridone dyes (and pigments) have became of interest in last several decades due to the high molar extinction coefficient, and the medium to high light ...

Synthesis and Evaluation of Changes Induced by Solvent and Substituent in Electronic Absorption Spectra of New Azo Disperse Dyes Containig Barbiturate Ring

Journal of Spectroscopy, 2013
Six azo disperse dyes were prepared by diazotizing 4-amino hippuric acid and coupled with barbituric acid and 2-thiobarbituric acid. Then, the products were reacted with aromatic aldehyde, sodium acetate, and acetic anhydride, and oxazolone derivatives ...

Liver organoids: modelling complexity in homeostasis and disease

FEBS Letters, EarlyView.
Studying liver in vitro has been challenging because simple 2D cell cultures fail to capture liver's cellular and architectural complexity. To bridge this gap, scientists increasingly use organoids, 3D liver models which better mimic liver composition and function. This review examines recent advances in liver organoid complexity and realism, discusses

Invisible but not inaccessible—Revealing transient oligomers formed by intrinsically disordered proteins with solution NMR and complementary methods

FEBS Letters, EarlyView.
Transient oligomers formed by intrinsically disordered proteins may be ‘invisible’ to direct detection yet remain accessible to solution NMR through equilibrium‐exchange measurements and pressure‐jump experiments. Complementary methods report on mass, stoichiometry, selected distance distributions, morphology, and internal packing.

Treatment of Kynol fiber materials – Part 1: dyeing processes

Communications in Development and Assembling of Textile Products, 2022
Kynol fibers are excellent flame-retardant materials used for manifold applications. These fibers exhibit originally an orange coloration. Up to now, dyeing processes for Kynol fibers are less reported, and the functionalization of these fibers by ...

MITF maintains genome stability in nonmelanocyte lineages

Molecular Oncology, EarlyView.
MITF is essential for melanocyte survival and acts as an oncogene in 10%–20% of melanomas. We show that MITF depletion causes genome instability in nonmelanocytic cells, leading to LATS2‐mediated P53 activation, cell cycle arrest, and apoptosis. This study highlights the role of MITF as a genome maintenance factor beyond the melanocyte lineage. Created

Utilization of Cuscuta japonica powder as a novel affordable adsorbent for removing disperse dyes from water

Discover Chemistry
Textile industrial activities have become major contributors of water pollution through the release of dyes into water systems. Disperse red 13 and disperse orange 3 dyes are still heavily used in the industry despite having been reported to be ...

Preparation of Ultrafine Disperse Dyes Based on the Efficiency Balance of Grinding and Dyeing

Journal of Chemistry, 2022
As dispersive dyes are nonionic dyes, the particle size and particle-size distribution will significantly affect the dyeing performance. In this study, the grinding conditions, the granularity of disperse dye, and the dyeing performance were combined to ...

CEACAM1 participation in breast cancer progression

Molecular Oncology, EarlyView.
In invasive breast cancer (BC), CEACAM1 shifts from an apical to a uniform membranous/cytoplasmic pattern, or is lost, as tumors dedifferentiate, inversely tracking the Ki‐67 proliferative index. In MCF‐7 cells, only CEACAM1‐4L suppresses proliferation, repressing cell cycle and growth factor genes.
