Changes in the Expression of Thin Filament-Associated Proteins in Colonic Smooth Muscle from Mice During Inflammation
… others have shown that inflammation induced by TNBS treatment alters the expression and/or activity of signaling molecules involved in the regulation of Ca2+ mobilization, MLC20 phosphorylation and contraction in colonic smooth muscle. Although, thin filament- associated proteins such as …

Selective damage to and protection of enteric neurons in vitro in models of ischemia and reperfusion
… in the 2, 4, 6-trinitrobenzene sulfonic acid (TNBS)-model of colitis in adult rats. By Day 2 of TNBS-induced colitis, HIF1-α presence in the nuclei of myenteric neurons had significantly increased, indicating hypoxic challenge. Despite the potential for ischemia to occur in inflammation, little …

Synthetic polymer-collagen composite hydrogel for drug delivery and tissue engineering
… by the use of equipments such as NMR and DSC or TNBS reagent were carried out to investigate the extent of successful crosslinking. Water contact angle and cell cytotoxicity study were also conducted to examine the biocompatibility of this material.

Photoaffinity labeling the nucleotide sites of the sarcoplasmic reticulum Ca²⁺-ATPase
… of the resulting 8N₃-nucleotide with TNBS. Inclusion of the oxidizing agent, DTNB, in the final reaction was found to be necessary to prevent reduction of the azido group by the released sulfite anion and also elevated the yield of trinitrophenylation to about 80%. Purity was …

Einflüsse von 17β-Östradiol, ER-subtypspezifischen Agonisten und Phytoöstrogenen auf inflammatorische Prozesse im Kolon
… zwei Nagermodellen (HLA-B27 transgene Ratte und TNBS-induzierte Kolitis) analysiert. Ein Ernährungsexperiment, in dem eine Gruppe der Tiere bereits in utero sowie postnatal über Muttermilch und Futter hohen Phytoöstrogenspiegeln ausgesetzt war, zeigte wider Erwarten keine antiinflammatorischen …

Preparation, development and evaluation of novel drug delivery systems for colon targeting
… in vivo usando il modello di colite indotta da TNBS in ratti. Sistemi enzima-dipendenti sono stati preparati con il metronidazolo attraverso la sintesi di profarmaci del MTZ, legando covalentemente il farmaco alla α-, β- e γ-ciclodestrina e al chitosano. Tutti i profarmaci sono stati …

The measurement of available lysine in textured soy protein
… soybeans. The Kakade and Liener (1969) TNBS procedure provided a quick reproducible measure of lysine availability. The results of this study indicated that lysine availability in textured soy protein was not altered significantly during processing.

Creation of Ovalbumin Based Scaffolds for Bone Tissue Regeneration
… previously shown to promote cellular response. A TNBS assay determined percent crosslinking in the scaffolds, however there was no significant difference in percent crosslinking despite differing GA concentrations used. Possible explanations include an excess of GA was used. Using DSC, a glass …

Preparation, characterisation and functional applications of whey protein-carbohydrate conjugates as food ingredients
… (OPA) and trinitrobenzenesulfonic acid (TNBS) methods due to the amino groups being located within large, dense protein aggregates. Overall, the findings presented in this thesis constitute a significant advancement of the body of knowledge on whey protein/peptide-carbohydrate conjugate …

Consequences of Aryl Hydrocarbon Receptor Activation in Crohn's Disease
… TCDD and the natural ligand I3C. TCDD suppressed TNBS-induced colitis, as demonstrated by the decreased disease severity and dampened inflammation in the gut. TCDD-treated mice exhibited decreased inflammatory mediator production and increased frequency of regulatory cells, both Foxp3+ Tregs and …

Enzymatic treatment of polyamide 6.6 fibres
… the compound 2,4,6-trinitrobenzenesulfonic acid (TNBS) with the amino groups released to the bath treatment and the other one is based on the reaction of a specific wool reactive dye with the terminal amino groups at the surface of the treated fabrics. In this work it was proved that the enzymatic …
