Gut microbiome‐derived metabolites show promise in cancer research and therapy

Interdisciplinary Medicine, EarlyView.
The metabolites produced by the gut microbiome, which are subject to regulation by multiple factors, play a pivotal role in the progression of various types of cancer. These metabolites not only function as potential biomarkers for the early detection and monitoring of tumor development, but also actively participate in cancer therapeutic processes ...

Electrochemical Reduction of Quinones in Different Media: A Review

International Journal of Electrochemistry, 2011
The electron transfer reactions involving quinones, hydroquinones, and catechols are very important in many areas of chemistry, especially in biological systems. The therapeutic efficiency as well as toxicity of anthracycline anticancer drugs, a class of

Benzoquinonas, hidroquinonas e sesquiterpenos de Auxemma glazioviana Benzoquinones, hydroquinones and sesquiterpenes of Auxemma glazioviana

Química Nova, 2005
Two new compounds, 5 and 8, and an epimeric mixture 4a/4b were isolated from hardwood of Auxemma glazioviana. Their structures and relative configurations were determined by modern spectroscopic analysis to be rel-10alpha,11alpha-epoxy-11beta-ethoxy ...

Clinical and Histopathological Assessment of the Field of Cancerization in Human Skin Before and After Treatment With a 1927‐nm Thulium Fractional Laser

Lasers in Surgery and Medicine, EarlyView.
ABSTRACT Background Field cancerization is a major concern in photodamaged skin due to its risk of progression to squamous cell carcinoma. The 1927‐nm thulium laser has emerged as a promising therapy, but its isolated effects on this condition remain underexplored.

β-lapachone suppresses tumour progression by inhibiting epithelial-to-mesenchymal transition in NQO1-positive breast cancers

Scientific Reports, 2017
NQO1 is a FAD-binding protein that can form homodimers and reduce quinones to hydroquinones, and a growing body of evidence currently suggests that NQO1 is dramatically elevated in solid cancers.

The effects of bicarbonate and mineral surfaces on uranium immobilization under anaerobic conditions [PDF]

, 2011
For four decades, from 1940 through 1980, the U.S. Department of Energy (DoE) extensively mined and processed uranium at various sites. As a result, widespread uranium contamination exists in subsurface sediments and aquifers.

Structural Characterization of Porous Photo‐Crosslinked Hybrid Networks Based on Collagen‐Poly(Trimethylene Carbonate)

Macromolecular Materials and Engineering, EarlyView.
Hybrid networks combining natural and synthetic polymers into one network may result in networks with good bioactivity, suitable mechanical properties, and high control over degradation. This study shows that phase‐separated networks are obtained with the collagen phase acting as multifunctional crosslinks.

Glyco‐Nanogels for Modulating Pseudomonas aeruginosa Biofilm

Macromolecular Rapid Communications, EarlyView.
Nanogels presenting α‐galactose and β‐fucose can significantly alter Pseudomonas aeruginosa biofilm dynamics through their interaction with lectins. Application timing is crucial: pre‐treatment reduces biofilm, while treatment after biofilm initiation increases biomass.

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

Macromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.
