Cu or Fe‐Exchanged Natural Clinoptilolite as Sustainable Light‐Assisted Catalyst for Water Disinfection at Near Neutral pH

open access: yesChemPlusChem, EarlyView.
Fe and Cu exchanged natural clinoptilolites are evaluated as heterogeneous photo‐Fenton catalysts for water disinfection under visible light, using E. coli as a model pathogen. Bacterial detection limit is reached in 2 h, with no regrowth observed.

Invasive non-typhoidal Salmonella in sickle cell disease in Africa: is increased gut permeability the missing link?

open access: yesJournal of Translational Medicine, 2018
Non-typhoidal Salmonella usually induces self-limiting gastroenteritis. However, in many parts of Africa, especially in individuals who are malnourished, infected with malaria, or have sickle cell disease, the organism causes serious and potentially ...

Supersulfide biology and translational medicine for disease control

open access: yesBritish Journal of Pharmacology, EarlyView., 2023
Abstract For decades, the major focus of redox biology has been oxygen, the most abundant element on Earth. Molecular oxygen functions as the final electron acceptor in the mitochondrial respiratory chain, contributing to energy production in aerobic organisms. In addition, oxygen‐derived reactive oxygen species including hydrogen peroxide and nitrogen

Recent Advances and Constructing Strategies of Chemiluminescence‐ and Bioluminescence‐Based Photodynamic Therapy

open access: yesChemPhotoChem, EarlyView.
Photodynamic therapy (PDT) is a noninvasive therapy for cancer and many other diseases. A PDT system includes three key components: a light source, photosensitizers (PSs), and oxygen. Internal light sources, such as chemiluminescence (CL) and bioluminescence (BL), trigger PDT without external irradiation, allowing for more flexibility.

Intestinal Barrier Glycosylation for Gut Physiology and Pathology

open access: yesBarrier Immunity, EarlyView.
ABSTRACT The intestinal barrier is a selective structure that safeguards the body from external threats while permitting nutrient absorption and immune surveillance. It consists of the outer mucus layer, the intermediate layer of intestinal epithelial cells (IECs), and the inner layer of immune cells. The proteins in the mucus layer and within IECs are
