Supramolecular Gels as Active Tools for Reaction Engineering

Angewandte Chemie, EarlyView.
The unique combination of environments within gels, self‐assembled from low‐molecular‐weight gelators, offers the ability to control reactivity in new ways, achieving unique reaction outcomes, leading to the emerging concept of supramolecular gels as nanoreactors. Smart chemical engineering methods enable the use of such gels to fabricate materials and

An Artificial Metal‐Free Peroxidase Designed Using a Ferritin Cage for Bioinspired Catalysis

Angewandte Chemie, EarlyView.
Designing artificial enzymes remains challenging due to the need for precise active site control. Here, we present a simple strategy to create metal‐free artificial enzymes by engineering Histidine clusters inside a ferritin cage. The resulting catalyst mimics peroxidase activity, and its stable cage structure offers new insights into supramolecular ...

Heme iron from meat and risk of colorectal cancer: a meta-analysis and a review of the mechanisms involved [PDF]

, 2011
Red meat and processed meat intake is associated with a risk of colorectal cancer, a major cause of death in affluent countries. Epidemiological and experimental evidence supports the hypothesis that heme iron present in meat promotes colorectal cancer ...

THE ELECTROMETRIC TITRATION OF HEMIN AND HEMATIN

Journal of Biological Chemistry, 1928
It was shown 5 years ago (1) that the change from methemoglobin to hemoglobin could be studied by an electrochemical method. The reduction by means of sodium hydrosulfite and the oxidation of the reduced compound (hemoglobin) by ferricyanide were found to involve 1 equivalent. These results have been confirmed and extended in later work (2).

OXIDATIVE CHANGES OF LIPIDS, PROTEINS AND ANTIOXIDANTS IN YOGURT DURING THE SHELF LIFE [PDF]

, 2017
Background: Oxidation processes in milk and yogurt during the shelf life can result in an alteration of protein and lipid constituents. Therefore, the antioxidant properties of yogurt in standard conditions of preservation were evaluated. Results: Total

Functional characterization of RhuB as a second TonB2-dependent hemin receptor in Riemerella anatipestifer CH-1

Microbiology Spectrum
In the previous study, it was shown that Riemerella anatipestifer (R. anatipestifer, RA), a pathogen in ducks and some other birds, encodes a hemin uptake system. The R.

Hemin treatment drives viral reactivation and plasma cell differentiation of EBV latently infected B cells.

PLoS Pathogens, 2023
Epstein-Barr virus (EBV) and Plasmodium falciparum have a well described role in the development of endemic Burkitt lymphoma (BL), yet the mechanisms involved remain unknown.

Multimodal Deep Learning for Personalized Renal Cell Carcinoma Prognosis: Integrating CT Imaging and Clinical Data [PDF]

arXiv, 2023
Renal cell carcinoma represents a significant global health challenge with a low survival rate. This research aimed to devise a comprehensive deep-learning model capable of predicting survival probabilities in patients with renal cell carcinoma by integrating CT imaging and clinical data and addressing the limitations observed in prior studies. The aim

HemU and TonB1 contribute to hemin acquisition in Stenotrophomonas maltophilia

Frontiers in Cellular and Infection Microbiology
IntroductionThe hemin acquisition system is composed of an outer membrane TonB-dependent transporter that internalizes hemin into the periplasm, periplasmic hemin-binding proteins to shuttle hemin, an inner membrane transporter that transports hemin into

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

Advanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent
