Receptor‐Dependent and ‐Independent Effects of Hemin on Platelet Plasma Membrane Disintegration

open access: yesThe FASEB Journal, Volume 40, Issue 2, 31 January 2026.
Microhemorrhages lead to the release of erythrocytes, which are then degraded and lysed. These hemolyses result in the liberation of free iron‐containing hemin. Hemin induces platelet activation and ferroptosis. Inhibition of GPVI/CLEC‐2 receptor‐mediated ITAM‐signaling inhibits hemin‐induced platelet activation (low hemin concentrations). Deferoxamine,

Metal Nanoclusters for Cancer Imaging and Treatment

open access: yesAdvanced Functional Materials, Volume 36, Issue 2, 5 January 2026.
This review aims to provide a comprehensive summary and discussion of the core–shell design capabilities of metal nanoclusters (NCs) at the atomic level for cancer imaging and treatment. It offers essential insights into the design principles of metal NCs while also encouraging the exploration of other nanomaterials and their potential theranostic ...

Total Synthesis and Conformational Analysis of Monophenyl Substituted Protoporphyrins. IX

open access: yes, 2000
- The total synthesis of meso-monoaryl protoporphyrins ( 1 ) and ( 2 ) using a MacDonald type [2+2] condensation is described. In this method a bisformyl dipyrrylmethane is treated with a biscarboxydipyrrylmethane. Attempts to obtain the δ -meso-monoaryl

In Situ Assembly of Transformable Monopeptide on Activated Neutrophils Attenuates NETs‐Induced Hepatocellular Carcinoma Metastasis by Disrupting NE Nuclear Translocation

open access: yesAdvanced Science, Volume 13, Issue 1, 5 January 2026.
Activated neutrophils release extracellular traps (NETs) that promote tumor metastasis. FTP‐NPs are develpoed, a peptidic nanomaterial that binds NE on neutrophil membranes, forming NE‐fibril clusters that deactivate NE and prevent NETs formation. This strategy reduces metastasis and enhances the anti‐tumor immune response by targeting NE subcellular ...

A Growth‐Coupled Evolutionary Strategy Enhances Heme Biosynthesis in Saccharomyces cerevisiae

open access: yesBiotechnology Journal, Volume 21, Issue 1, January 2026.
Graphical Abstract and Lay Summary Introducing a plasmid with a heme‐responsive promoter connected to a growth‐promoting gene into Saccharomyces cerevisiae created a positive feedback loop between intracellular heme levels and cell growth. After 100 h of adaptive evolution, the plasmid was removed, resulting in a mutant strain that exhibited an ...

Chairside testing for cariogenic bacteria: current concepts and clinical strategies [PDF]

open access: yes, 2008
Modern approaches to dental caries such as STEM (System for Total Environmental Management) are based on a whole-of-patient and whole-of-biofilm approach to the disease.

Cobalt protoporphyrin IX increases endogenous G-CSF and mobilizes HSC and granulocytes to the blood [PDF]

open access: yes, 2019
Granulocyte colony-stimulating factor (G-CSF) is used in clinical practice to mobilize cells from the bone marrow to the blood; however, it is not always effective. We show that cobalt protoporphyrin IX (CoPP) increases plasma concentrations of G-CSF,

Protoporphyrin Production of Tetrahymena geleii

open access: yesExperimental Biology and Medicine, 1953
SummaryA strain of Tetrahymena geleii W at the end of its rapid phase of growth on solid media in darkness turns red-brown. The main pigment component has been identified as protoporphyrin. A minor component containing protoporphyrin appears to be bound to some fatty material.
