Application Of Fructans-Degrading Lachancea Fermentati Fst5.1 As An Alternative To Baker’S Yeast In The Production Of A Low-Fodmap Whole Wheat Bread., Małgorzata Borowska

ORBioM (Open Research BioSciences Meeting)

FODMAPs are a group of poorly absorbed dietary carbohydrates comprised of easily fermentable oligo-, di-, monosaccharides and polyols. When consumed, they can exert gastrointestinal symptoms of pain, flatulence, or an irregular bowel movement in individuals with irritable bowel syndrome. Whole wheat bread is an excellent source of proteins, vitamins, polyphenols, and other nutrients, but its consumption is restricted in a low-FODMAP diet due to high fructans content. Although alternatives exist, these are primarily gluten-free, often inferior in terms of quality, nutritional profile, and consumer acceptance. Bioprocessing using microbial fermentation has a proven capacity to reduce FODMAPs in cereal products, but …

Journal of Food and Drug Analysis

We aim to develop an efficient and non-invasive strategy for monitoring of drugs and their metabolites via human skin. Probe sampling was combined with thermal desorption-electrospray ionization tandem mass spectrometry (TD-ESI/MS/MS) to characterize trace terbinafine, which was secreted on patient’s skin after ingesting terbinafine tablets. The terbinafine ion signals were directly detected in the samples collected from different skin regions and the signals were monitored for 8 weeks. The detection and location of terbinafine via the skin suggest that the methods are useful in rapidly and noninvasively collecting the molecular information of the ingested drug on skin for pharmacokinetic studies.

Camphorataimide B Suppresses The Metastasis Of Human Colorectal Cancer Cell By Inhibiting Smad/Fak/Akt Axis And Promoting Degradation Of Snail/Bmp4 Complex, Chi-Chou Huang, Chia-Hung Hung, Yi-Ju Lee, Tsui-Hwa Tseng, Yean-Jang Lee, Shao-Hsuan Kao, Chau-Jong Wang

Journal of Food and Drug Analysis

Camphorataimide B (CamB) has anticancer activities against several tumors. Here, we aimed to investigate the mechanism(s) by which CamB inhibits metastasis of colorectal cancer (CRC) cells. Low-dose CamB did not affect the cell viability and cell cycle progression of CRC cells, but significantly inhibited the metastatic potentials of CRC cells. Mechanically, CamB reduced the protein and mRNA expression of BMP4, and inhibited Smad and FAK/Src/Akt signaling. CamB also decreased Snail levels by promoting its degradation via proteasome and thereafter reduced Snail-mediated BMP4 transcription. Moreover, CamB considerably inhibited the in vivo metastasis of DLD-1 cells in xenograft mice.
