Ultra-performance hydrophilic interaction liquid chromatography coupled with tandem mass spectrometry for simultaneous determination of allopurinol, oxypurinol and lesinurad in rat plasma: Application to pharmacokinetic study in rats.

open access: yesPLoS ONE, 2019
A fixed dose combination of lesinurad and allopurinol has been recently approved by USFDA and EMA for treatment of gout-associated hyperuricemia in patients who have not achieved target serum uric acid levels with allopurinol alone.

Protein hydrolysates in cell culture: Toward multi‐omics characterization

open access: yesBiotechnology Progress, Volume 42, Issue 4, July/August 2026.
While protein hydrolysates are widely used in cell culture applications, they remain undefined and variable products. Multi‐omic characterization evaluating composition and function can transition hydrolysates toward semi‐defined media components.

A Novel HILIC‐UPLC‐DAD‐MS/MS Method for the Analysis of Mycosporine‐Like Amino Acids and Their Quantification in Diverse Algae

open access: yesELECTROPHORESIS, Volume 47, Issue 7, Page 620-628, July 2026.
The separation of selected mycosporine‐like amino acids and two biosynthetic precursors, in total 13 compounds, by HILIC‐UPLC is described for the first time. With an analysis time of only 5 min, it surpasses all currently known methods for analysis of these promising natural products.

Effect of Chitooligosaccharides‐Combination Fortified Noodles Intervention on Visceral Adiposity and Serum Metabolites in a High‐Risk Occupational Cohort of Young Seafarers

open access: yesFood Science &Nutrition, Volume 14, Issue 7, July 2026.
In a 4‐week self‐controlled trial of 73 young seafarers, consumption of chitooligosaccharides‐combination fortified noodles every other day significantly reduced visceral fat area, waist circumference, serum leptin, and LDL‐C, and elevated skeletal muscle index, without altering body weight.

Provenance legacies override species effects in shaping oak rhizosphere microbiomes and metabolomes

open access: yesNew Phytologist, Volume 251, Issue 1, Page 488-504, July 2026.
Graphical representation of experimental setup. Quercus spp. seeds were collected at two origins: upper Rhine basin (URB) and north German lowland (NGL). Summary As climate change drives more frequent drought‐heat extremes, selecting drought‐tolerant trees is crucial for future forest resilience. However, the role of tree–microbial associations remains

Endophyte‐induced systemic spatial reprogramming of metabolism in Populus trichocarpa roots under drought

open access: yesNew Phytologist, Volume 251, Issue 1, Page 438-454, July 2026.
Summary Beneficial, facultative endophytes help plants thrive in challenging environments by altering their host's metabolism, but how these cellular scale metabolic changes propagate to the systems biology scale is unknown. In this work, we employed a high‐resolution chemical imaging approach to map metabolic changes at the Populus trichocarpa root ...

Crystal Structure and Conformational Dynamics of N─N Bond‐Forming Piperazate Synthase

open access: yesChemBioChem, Volume 27, Issue 12, 26 June 2026.
Piperazate synthases (PZSs) catalyze the key N─N bond formation in the biosynthesis of the rare amino acid piperazic acid. X‐ray crystal structures of apo‐ and holo‐SbPZS show a dimeric enzyme with two heme‐containing active sites, where histidine residues coordinate the iron centers.

Dilute and Shoot: A novel approach for determination of chlormequat and mepiquat in beer

open access: yesKvasný průmysl
The extensive use of pesticides in agriculture has led to the presence of their residues in soil, water sources, and crops. Among these, the plant growth regulators chlormequat and mepiquat are commonly employed to regulate plant growth.

Farmacocinética comparada de metformina, en forma sólida y en formulación extemporánea líquida para pediatría, en voluntarios adultos sanos

open access: yesActa Pediátrica de México, 2016
ANTECEDENTES: fraccionar o pulverizar tabletas de metformina para ajustar dosis pediátricas dificulta su administración, genera inestabilidad del fármaco (oxidación/fotosensibilidad) y relativiza su biodisponibilidad.
