Fluorescence Behavior of Water‐Soluble Porphyrins Immobilized on LTA Zeolite and Its Chlorogenic Acid Polyphenol Sensing in Coffee Wastewater

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
During coffee bean and cherry washing, contaminants are released into water, making this process a major source of water pollution. Chlorogenic acid can be efficiently detected using hybrid zeolite–porphyrin materials by measuring fluorescence quenching, achieving detection limits lower than current regulatory thresholds.

Myocardial inflammation is associated with impaired mitochondrial oxidative capacity in ischaemic cardiomyopathy

ESC Heart Failure, Volume 12, Issue 2, Page 1246-1255, April 2025.
Abstract Aims Myocardial inflammation and impaired mitochondrial oxidative capacity are hallmarks of heart failure (HF) pathophysiology. The extent of myocardial inflammation in patients suffering from ischaemic cardiomyopathy (ICM) or dilated cardiomyopathy (DCM) and its association with mitochondrial energy metabolism are unknown.

Spectrophotometric Determination of Levofloxacin in Pharmaceutical Formulations

, 2009
A simple. sensitive and accurate spectrophotometric method has been developed for the assay of levofloxacin (LEVO), which is based on the complexation of drug with copper(II) at pH 5.0.

Exploiting Biocatalysis for the Scalable Synthesis of Enantiopure γ‐Hydroxynitrile Building Blocks

European Journal of Organic Chemistry, EarlyView.
Screening a panel of (S)‐and (R)‐selective alcohol dehydrogenases identified several biocatalysts for stereoselectively reducing γ‐ketonitriles into γ‐hydroxynitriles. These processes were optimized, delivering the targets in yields up to 88% with e.e.’s up to 99%. Scalability of the methodology was achieved to produce gram quantities of product, which

Production of bioethanol from residual barley and utilization of fermentation co‐products in animal nutrition

Environmental Progress &Sustainable Energy, EarlyView.
Abstract The search for sustainable alternatives for bioethanol production has encouraged the valorization of agro‐industrial residues. This study evaluated the use of residual barley as a feedstock for bioethanol production and as a potential ingredient for ruminant feed.

Inconsistent Transcriptomic Responses to Hexabromocyclododecane in Japanese Quail: A Comparative Analysis of Results From Four Different Study Designs

Environmental Toxicology and Chemistry, EarlyView.
Abstract Efforts to use transcriptomics for toxicity testing have classically relied on the assumption that chemicals consistently produce characteristic transcriptomic signatures that are reflective of their mechanism of action. However, the degree to which transcriptomic responses are conserved across different test methodologies has seldom been ...
