Metabolomic Analysis Reveals Contributions of Citric and Citramalic Acids to Rare Earth Bioleaching by a Paecilomyces Fungus. [PDF]

open access: yes, 2019
Conventional methods for extracting rare earth elements from monazite ore require high energy inputs and produce environmentally damaging waste streams. Bioleaching offers a potentially more environmentally friendly alternative extraction process.

Selective Oxygenation of 3,4‐Dihydro‐2H‐Pyran to 5,6‐Dihydro‐2H‐Pyran‐2‐One With Pd/C Catalyst and Molecular Oxygen

open access: yesChemSusChem, Volume 19, Issue 7, 14 April 2026.
Selective oxygenation: The oxidation of 3,4‐dihydro‐2H‐pyran, which can be produced from lignocellulose‐derived furfural, was investigated with various catalysts using O2 as an oxidant in a H2O solvent. 5,6‐dihydro‐2H‐pyran‐2‐one, a value‐added product, was obtained in 52% yield with reusable Pd/C catalyst.

Fucoidan Rescues p-Cresol-Induced Cellular Senescence in Mesenchymal Stem Cells via FAK-Akt-TWIST Axis

open access: yesMarine Drugs, 2018
Mesenchymal stem cells (MSCs) are a source for cell-based therapy. Although MSCs have the potential for tissue regeneration, their therapeutic efficacy is restricted by the uremic toxin, p-cresol, in chronic kidney disease (CKD).

Effects of ultrasound on electrochemical oxidation mechanisms of p-substituted phenols at BDD and PbO2 anodes [PDF]

open access: yes, 2010
The effects of low-frequency (40 kHz) ultrasound are investigated with regard to the effectiveness and mechanisms of electrochemical oxidation of p-substituted phenols (p-nitrophenol, p-hydroxybenzaldehyde, phenol, p-cresol, and p-methoxyphenol) at BDD ...

Improvised method for urinary p-cresol detection and measurement using high performance liquid chromatography/mass spectrometry

open access: yesHeliyon, 2019
Gut microbiota has been implicated in many disorders including Autism Spectrum Disorder (ASD). ASD is a neurodevelopmental brain disorder affecting individuals leading to restricted and repetitive pattern of behaviour and disruption of communication and ...

In search of cues: dung beetle attraction and the significance of volatile composition of dung [PDF]

open access: yes, 2018
Volatile organic compounds (VOCs) provide animals with multiple cues about location, type, and condition of valuable resources such as food. In particular, odour cues are often essential for the localization and discrimination of resources with patchy ...

Heterogeneous Reaction of Gaseous Ozone with Aqueous Iodide in the Presence of Aqueous Organic Species [PDF]

open access: yes, 2010
The fast reaction of gaseous ozone, O_3(g), with aqueous iodide, I−(aq), was found to be affected by environmentally relevant cosolutes in experiments using cavity ring-down spectroscopy (CRDS) and electrospray ionization mass spectrometry (ESIMS) for ...

The fecal microbiome and serum concentrations of indoxyl sulfate and p‐cresol sulfate in cats with chronic kidney disease

open access: yesJournal of Veterinary Internal Medicine, 2018
Background Intestinal dysbiosis has been documented in humans with chronic kidney disease (CKD) and is thought to contribute to production of the uremic toxins indoxyl sulfate (IS) and p‐cresol sulfate (pCS).

Molecular Interaction Studies in Binary Liquid Mixtures from Ultrasonic Data

open access: yesE-Journal of Chemistry, 2010
Ultrasonic velocities and densities of the binary liquid mixtures of dimethy1 sulphoxide (DMSO) with phenol, o-cresol, m-cresol, p-cresol and p-chlorophenol at 318.15 K, over the entire composition range were measured.
