Urinary metabolic fingerprinting of mice with diet-induced metabolic derangements by parallel dual secondary column-dual detection two-dimensional comprehensive gas chromatography.

J. Chromatogr. A. 1361 , 265-76, (2014)

This study investigates the potential of a parallel dual secondary column-dual detection two-dimensional comprehensive GC platform (GC×2GC-MS/FID) for metabolic profiling and fingerprinting of mouse urine. Samples were obtained from a murine model that mimics...

The identification of a novel SIRT6 modulator from Trigonella foenum-graecum using ligand fishing with protein coated magnetic beads.

J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 968 , 105-11, (2014)

SIRT6 is a histone deacetylase that has been proposed as a potential therapeutic target for metabolic disorders and the prevention of age-associated diseases. Thus the identification of compounds that modulate SIRT6 activity could be of great therapeutic impo...

Discovery of optimal zeolites for challenging separations and chemical transformations using predictive materials modeling.

Nat. Commun. 6 , 5912, (2015)

Zeolites play numerous important roles in modern petroleum refineries and have the potential to advance the production of fuels and chemical feedstocks from renewable resources. The performance of a zeolite as separation medium and catalyst depends on its fra...

cIEF for rapid pKa determination of small molecules: a proof of concept.

Eur. J. Pharm. Sci. 63 , 14-21, (2014)

A capillary isoelectric focusing (cIEF) method was developed for the determination of the ionization constants (pKa) of small molecules. Two approaches used to decrease the electroosmotic flow (EOF) were compared: (i) a hydroxypropylcellulose (HPC) coated cap...

Antioxidant and antiproliferative activities of polysaccharide fractions from litchi pulp.

Food Funct. 6 , 2598-606, (2015)

Three litchi polysaccharide fractions (LPFs), LP-4, LP-6 and LP-8, were obtained by fractional precipitation using 40%, 60% and 80% ethanol, respectively. The physicochemical properties, chemical antioxidant, and cellular antioxidant and antiproliferative act...

Metabolic study of androsta-1,4,6-triene-3,17-dione in horses using liquid chromatography/high resolution mass spectrometry.

J. Steroid Biochem. Mol. Biol. 152 , 142-54, (2015)

Androsta-1,4,6-triene-3,17-dione (ATD) is an irreversible steroidal aromatase inhibitor and is marketed as a supplement. It has been reported to effectively reduce estrogen biosynthesis and significantly increase the levels of endogenous steroids such as dihy...

CO₂ controlled flocculation of microalgae using pH responsive cellulose nanocrystals.

Nanoscale 7 , 14413-21, (2015)

Cellulose nanocrystals were grafted with imidazole functionalities up to DS 0.06 using a one-pot functionalization strategy. The resulting nanocrystals were shown to have a pH responsive surface charge which was found to be positive below pH 6 and negative ab...

Highly charged cellulose-based nanocrystals as flocculants for harvesting Chlorella vulgaris.

Bioresour. Technol. 194 , 270-5, (2015)

This study presents a novel flocculant for harvesting Chlorella vulgaris as model species for freshwater microalgae based on cellulose nanocrystals (CNCs), thus synthesized from a renewable and biodegradable resource. Cationic pyridinium groups were grafted o...

Abiogenic Syntheses of Lipoamino Acids and Lipopeptides and their Prebiotic Significance.

Orig. Life Evol. Biosph. 45 , 427-37, (2015)

Researchers have formed peptide bonds under a variety of presumed prebiotic conditions. Here it is proposed that these same conditions would have also formed amide bonds between fatty acids and amino acids, producing phosphate-free amphipathic lipoamino acids...

Structural features of a novel polysaccharide isolated from a New Zealand Maori mushroom Iliodiction cibarium.

Carbohydr. Res. 406 , 19-26, (2015)

A purified water-soluble fraction (ICP5) of a polysaccharide, isolated from a local Maori mushroom Iliodiction cibarium in New Zealand, was investigated for its structural properties. Size exclusion chromatography and dynamic light scattering showed that ICP5...
