Targeted metabolomics reveals novel diagnostic biomarkers for colorectal cancer

Molecular Oncology, EarlyView.
This study employed targeted metabolomic profiling to identify 302 distinct metabolites present in platelet‐rich plasma (PRP), revealing aberrant metabolic profiles amongst individuals diagnosed with colorectal cancer (CRC). Compared to carcinoembryonic antigen (CEA) and cancer antigen 19‐9 (CA199), our metabolite panel showed improved sensitivity ...

Temperature‐ and pH‐Responsive Polymeric Photocatalysts for Enhanced Control and Recovery

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
Stimuli‐responsive photocatalytic materials have emerged that are not only able to efficiently catalyze reactions but can use external stimuli to modulate their physical properties. This technique has been used to control the reactivity of a photocatalytic material turning it on/off. Moreover, photocatalytic materials have been synthesized which can be

A First Plasmodium vivax Natural Infection Induces Increased Activity of the Interferon Gamma-Driven Tryptophan Catabolism Pathway

Frontiers in Microbiology, 2020
The human immune response that controls Plasmodium infection in the liver and blood stages of the parasite life cycle is composed by both pro- and anti-inflammatory programs.

Peripheral blood leukocyte signatures as biomarkers in relapsed ovarian cancer patients receiving combined anti‐CD73/anti‐PD‐L1 immunotherapy in arm A of the NSGO‐OV‐UMB1/ENGOT‐OV30 trial

Molecular Oncology, EarlyView.
Using mass cytometry, we analyzed serial blood samples from patients with relapsed epithelial ovarian cancer (EOC) treated with oleclumab–durvalumab combination immunotherapy in the NSGO‐OV‐UMB1/ENGOT‐OV30 trial. Our analysis identified potential predictive, monitoring, and response biomarkers detectable through liquid biopsy. These findings facilitate

ROTATIONAL SPECTRUM OF TRYPTOPHAN [PDF]

Proceedings of the 69th International Symposium on Molecular Spectroscopy, 2014
The rotational spectrum of the natural amino acid tryptophan has been observed for the first time using a combination of laser ablation, molecular beams, and Fourier transform microwave spectroscopy. Independent analysis of the rotational spectra of individual conformers has conducted to a definitive identification of two different conformers of ...

Tryptophan‐sensing receptor GPR142 expression levels are directly regulated by proinflammatory cytokines in ghrelin‐producing cells

FEBS Open Bio, EarlyView.
GPR142, a tryptophan‐sensing receptor, stimulates gastrointestinal hormones like ghrelin and is linked to inflammation regulation. Proinflammatory cytokines suppress ghrelin production, while tryptophan levels decrease via IDO1 activation. Our findings reveal that proinflammatory cytokines directly regulate GPR142 expression in ghrelin‐producing cells,

The Single‐Component Flavin Reductase/Flavin‐Dependent Halogenase AetF is a Versatile Catalyst for Selective Bromination and Iodination of Arenes and Olefins**

Angewandte Chemie, Volume 134, Issue 51, December 19, 2022., 2022
The single component flavin reductase/flavin dependent halogenase AetF catalyzes halogenation of a diverse set of substrates. High site selectivity, activity on relatively unactivated substrates, and high enantioselectivity for atroposelective bromination and bromolactonization was demonstrated.

Utilising feed effectors and automated feeders for semi‐intensive pacific white shrimp (Litopenaeus vannamei) production

Aquaculture, Fish and Fisheries, Volume 2, Issue 6, Page 540-551, December 2022., 2022
Abstract Feed effectors have been suggested to improve the efficiency of plant‐based shrimp diets by increasing attractability and palatability. This research trial aimed to expand upon previous Pacific white shrimp (Litopenaeus vannamei) research involving plant‐based diets, feed effectors and passive acoustic monitoring (PAM) in a laboratory setting ...
