Separation of isomeric xylenes by pervaporation through cellulose ester membranes [PDF]

open access: yes, 1982
The interaction between the isomeric xylenes and different cellulose esters was investigated using solubility parameter considerations and through measurements of swelling values.

Synthesis of inositol phosphate-based competitive antagonists of inositol 1,4,5-trisphosphate receptors. [PDF]

open access: yes, 2016
Inositol 1,4,5-trisphosphate receptors (IP3Rs) are intracellular Ca(2+) channels that are widely expressed in animal cells, where they mediate the release of Ca(2+) from intracellular stores evoked by extracellular stimuli.

Butyration of Lignosulfonate with Butyric Anhydride in the Presence of Choline Chloride

open access: yesBioResources, 2015
A novel process was developed for the butyration of lignosulfonate (LS) with butyric anhydride in the presence of choline chloride at elevated temperatures. The degree of substitution (DS) was qualitatively and quantitatively determined by Fourier transform infrared spectroscopy using the baseline method.

New insight into butyrate metabolism [PDF]

open access: yesProceedings of the Nutrition Society, 2003
Butyrate is a C4acid produced by microbial fermentation of carbohydrates and protein in the large intestine of all animal species. The factor of prime importance for the production rate of butyrate in the lower gut is type and levels of non-digestible carbohydrates entering the large intestine.

Phenolic compounds as marker compounds for botanical origin determination of German propolis samples based on TLC and TLC-MS

open access: yesJournal of Applied Botany and Food Quality, 2013
Propolis, a complex mixture of different plant exudates collected and processed by honeybees, contains a wide range of bioactive substances. German propolis has so far only rarely been studied with respect to its constituents and botanical origin.

Comparison of Three Methods to Determine the Degree of Substitution of Quinoa and Rice Starch Acetates, Propionates, and Butyrates: Direct Stoichiometry, FTIR, and 1H-NMR

open access: yesFoods, 2020
Rice and quinoa starch esters were prepared by acylation using short-chain fatty acid anhydrides with different chain lengths (acetic, propionic, and butyric anhydride). A direct stoichiometric method based on the acylation reaction was used to determine

Interactions with water of mixed acetic-fatty cellulose esters [PDF]

open access: yes, 2011
Cellulose powder was acylated with mixtures containing acetic, fatty and acetic-fatty anhydrides to form acetic-fatty cellulose esters. The total degree of substitution (DS) of the mixed cellulose esters (MCE) ranged from 2x10-2 to 2.92.

Antagonistic Effects of Sodium Butyrate and N-(4-Hydroxyphenyl)-retinamide on Prostate Cancer

open access: yesNeoplasia: An International Journal for Oncology Research, 2007
Butyrates and retinoids are promising antineoplastic agents. Here we analyzed effects of sodium butyrate and N-(4-hydroxyphenyl)-retinamide (4-HPR) on prostate cancer cells as monotherapy or in combination in vitro and in vivo.
