Background/aims: Butyrate and factor XIII may improve ulcerative colitis; they also affect tissue and serum transglutaminase levels. We investigated the therapeutic potential of sodium butyrate and factor XIII and the role of transglutaminase during mucosal repair in experimental colitis.
Methods: Rats with induced colitis were treated with sodium butyrate, mesalamine, sodium butyrate plus mesalamine, or saline enemas. Thromboxane B2 was monitored as index of inflammation. In a fifth group, the effectiveness of intravenous Factor XIII was assessed.
Results: Sodium butyrate, alone or plus mesalamine, reduced histological activity from 13.7 +/- 1.7 (saline) to 2.5 +/- 1.3 and 2.3 +/- 1.1 (P < 0.01), respectively. Transglutaminase, reduced in the colons of the saline group (783 +/- 157 vs. normal 1800 +/- 192 mU/g; P < 0.01), returned toward normal values in the sodium butyrate or sodium butyrate plus mesalamine groups (1390 +/- 228 and 1226 +/- 172 mU/g, respectively; P < 0.01 vs. saline). Furthermore, sodium butyrate plus mesalamine reduced thromboxane B2 levels by day 5 (0.92 +/- 0.16 vs. saline 1.85 +/- 0.34 ng/mL; P < 0.05). Factor XIII therapy improved the histological picture (2.7 +/- 2.1 vs. saline 13.8 +/- 1.7; P < 0.01) and increased transglutaminase levels both in serum (2.81 +/- 0.11 vs. saline 1.45 +/- 0.09 mU/mL; P < 0.01) and in colon (1503 +/- 127 vs. saline 747 +/- 103).
Conclusions: Sodium butyrate and factor XIII improve colitis, sodium butyrate plus mesalamine reduce early thromboxane B2 synthesis, and transglutaminase(s) plays a role in ulcer healing.

1-Methylxanthine (1-MX) is the major metabolite of caffeine and paraxanthine and might contribute to their activity. 1-MX is an adenosine receptor antagonist and increases the release and survivability of neurotransmitters; however, no study has addressed the potential physiological effects of 1-MX ingestion. The aim of this study was to compare the effect of 1-MX on memory and related biomarkers in rats compared to control.

Nonstoichiometric pseudoprotic ionic liquids (NPPILs) are an emerging class of ionic liquids with interesting physical properties and intriguing prospects for technological applications. However, fundamental questions remain about the proton transfer equilibria that underlie their ionic character. We use a combination of nuclear magnetic resonance spectroscopy, infrared spectroscopy, and small-angle X-ray scattering to characterize the equilibria of trihexylamine/butyric acid and water/butyric acid mixtures.

The occurrence of off-flavor in osmanthus absolutes has emerged as a significant concern that could hinder its broad market acceptance and associated economic development. In this study, key off-flavor molecules in industrial osmanthus absolute were identified through sensomics and chemometric approaches. A group of 10 off-flavor (OF) samples, eliciting smoky/phenolic, sweaty/sour, and spicy odors, were compared with 10 pleasant aroma (PA) samples through various analyses, including overall aroma assessment, comprehensive chemical profiling, aroma extract dilution analysis (AEDA), and orthogonal partial least-squares-discriminant analysis (OPLS-DA).

The study was conducted to explore the relationship between arabinoxylan (AX) structure and microbial fermentation characteristics, and reveal molecular mechanism of AX on regulating immune function of the host. Results indicated that the group of wheat bran AX showed greater activity of feruloyl esterase, production of short chain fatty acids and ferulic acid compared with the blank group (P < 0.05).

Inflammation-proliferation transition plays a key role in the successful healing of a common burn type, second-degree burn. Gynura procumbens in vitro adventitious root nanohydrogel is currently being studied for its immunomodulatory to improve reparative environment. Root production and nanohydrogel preparation was done respectively by in vitro propagation and emulsion/ solvent diffusion with carbomer as a polymer.
