“…Previously, we have shown that exogenous ET-1 induces the genes encoding type I collagen (COL1A1 and COL1A2) in human mesangial cells (19). Consistent with accumulation of type I collagen, ET-1 induces a myofibroblast-like phenotype in mesangial cells with secretion and deposition of excess extracellular matrix proteins (20).…”

“…Expression Profile-To identify potential determinants of collagen accumulation, we employed gene set enrichment analysis with the DAVID bioinformatics platform (23,24), using data from the Gene Ontology Consortium (25), to identify biological processes associated with our previously published set of 117 genes induced or repressed by ET-1 in human mesangial cells (available at the Gene Expression Omnibus under GEO accession numbers GSM9920 -GSM9931) (19). The statistical significance of enrichment for biological processes was calculated using a modified Fisher's exact p value, a cutoff of p Ͻ 0.05, and a Benjamini correction for multiple testing (26).…”

“…CUR is an infrequent diketone pigment which is distributed in plants. Because of the low toxicity, CUR is applied as a colorant in the field of foods (Mishra and Daswal, 2007;Epstein et al, 2010;Lüer et al, 2014), which is approved by the World Health Organization (WHO), the Food and Drug Administration (FDA), and many countries. In recent years, CUR is been one of the top-selling natural edible pigments.…”

A novel polymer of poloxamer188-b-PCL was synthesized via a ring-opening polymerization. Fourier transform infrared spectroscopy (FTIR), Raman, and 1 H nuclear magnetic resonance (1 H NMR) spectra were used to study the structures of obtained poloxamer188-b-PCL. The thermo-stability of poloxamer188-b-PCL was carried out with a thermal gravimetric analyzer (TGA), and cytotoxicity was obtained using the CCK8 method. Cargo-free and curcumin (CUR)-loaded poloxamer188-b-PCL NPs were fabricated via the solvent evaporation method. The morphology, particle size distribution, and stability of cargo-free NPs were studied with a scanning electron microscope (SEM) and laser particle analyzer. The in vitro radioprotection activity of CUR-loaded NPs was performed. FTIR, Raman, and 1 H NMR spectra confirmed that poloxamer188-b-PCL was obtained. TGA curves suggested poloxamer188-b-PCL had better thermo-stability than original poloxamer188. Cell tests suggested that the cargo-free NPs had no cytotoxicity. SEM image showed that the cargo-free NPs were spherical with a diameter of 100 nm. Free radical scavenging experiments proved that CUR-loaded NPs had better antioxidant activity than CUR solutions. CUR-loaded NPs could be detected in all tissues, including liver, kidneys and lung. In summary, this work demonstrated a feasibility of developing an injective formulation of CUR and provided a protection agent in caner radiotherapy.

“…One of the efficient approaches to overcome these drawbacks is to incorporate functional groups with a H‐donating nature into the PI backbone, allowing the design of one‐component hydrogen‐abstraction PIs that can initiate the photopolymerization without any co‐initiator . A series of benzophenone derivatives and thioxanthone derivatives, have been reported as efficient one‐component hydrogen‐abstraction PIs for FRP. It is still of great interest to continue such an exploration to solve the existing problems (e. g. most of these PIs only work under UV light and are used only for FRP) and enhance the photoinitiation efficiency.…”

Naphthalimide‐Tertiary Amine Derivatives as Blue‐Light‐Sensitive Photoinitiators

et al. 2018

View full text Add to dashboard Cite

The photochemical mechanism of the radical generation from photoinitiating systems based on 1, 8‐naphthalimide derivatives (ANDs; with tertiary amine moieties) are investigated by using various approaches including cyclic voltammetry, steady‐state photolysis, and electron spin resonance spin‐trapping techniques. It reveals that radicals can be produced from ANDs alone or ANDs/additive (e. g. iodonium salt or chloro triazine) combinations. The generated radicals and cations can initiate both free‐radical and cationic photopolymerization reactions under irradiation with various light‐emitting diodes or a halogen lamp. For most of the AND‐based photoinitiating systems, more than 60 % of acrylate or epoxide conversions were attained, and were even higher than those obtained by using commercial photoinitiators, for example, bisacylphosphine oxide or camphorquinone. More interestingly, the AND1‐based photoinitiating system can also initiate concomitant cationic/radical polymerizations and can be used for the synthesis of interpenetrated polymer networks.
