Formation of meso, N-diphenylprotoporphyrin IX by an aerobic reaction of phenylhydrazine with oxyhemoglobins.

open access: yes, 2003
Administration of phenylhydrazine to rabbits resulted in the denaturation of hemoglobins in erythrocytes, causing the formation of intracellular precipitates known as Heinz bodies, severe hemolytic anemia, and reticulocytosis.

Engineering a Hybrid Heme Pathway for Hemoprotein‐Based Dye‐Decolorizing Peroxidase in Escherichia coli

open access: yesFood Bioengineering, Volume 5, Issue 2, Page 209-219, June 2026.
In this study, the heme content and enzymatic activity of the RhDypB mutant strain RhDypB‐R80 were enhanced through optimized heme uptake and pathway integration. This engineered host presents a promising platform for hemoprotein engineering and holds potential for applications in controlling mycotoxin contamination in food products.

The chemistry of pyrrolic compounds. XLIV. The preparation and comparative spectroscopic study of some isomeric diformyldeuteroporphyrins

open access: yes, 1980
A comparative study of the electronic and 1H n.m.r. spectra of five isomeric diformyldeuteroporphyrins has been carried out. Clear distinctions can be recognized in the electronic spectra of the diformyldeuteroporphyrins, depending on the relative ...

Relationship of Genetic Variability (HIF‐1Α (rs11549465; P582S), TMPRSS6 (rs855791; V736A) and ABO (rs651007) and Iron Deficiency in Repeated Blood Donors in 2023: A Cross‐Sectional Study Towards Individualized Health Management

open access: yesHealth Science Reports, Volume 9, Issue 6, June 2026.
ABSTRACT Background and Aims Frequent blood donation can significantly increase the risk of iron deficiency, influenced by demographic, dietary, environmental, and genetic factors. This study aims to evaluate the association between iron deficiency and specific genetic variations (HIF‐1α (rs11549465; P582S), TMPRSS6 (rs855791; V736A), and ABO (rs651007)

White Adipose Tissue Browning and Cross Talk With Metabolic Diseases and Tumors: From Molecular Mechanisms to Clinical Translation

open access: yesMed Research, Volume 2, Issue 2, Page 280-308, June 2026.
White adipose tissue undergoes browning under endogenous and exogenous stimuli, primarily regulated by core molecules such as PRDM16 and UCP1. It exhibits a double‐edged sword effect in metabolic diseases and tumors: while mitigating metabolic disease impacts and suppressing early‐stage tumors through nutritional competition, it may accelerate cachexia

Theranostic Advancements in Brain Cancer: Promising Approaches for Emerging Therapy

open access: yesMedComm – Oncology, Volume 5, Issue 2, June 2026.
Strategies for improving intra‐arterial administration (A) and photodynamic therapy in brain cancer (B). Improving intra‐arterial (IA) administration and photodynamic therapy (PDT) for brain cancer involves enhancing tumor targeting and breaching the blood–brain barrier (BBB). Key strategies include super selective catheterization, using osmotic agents

Erythropoietic Protoporphyria and Surgery: A Case of Successful Mastectomy With Perioperative Light Shielding Strategies Based on Light‐Induced Hemolytic Threshold Assessment

open access: yesThe Journal of Dermatology, Volume 53, Issue 6, Page 930-933, June 2026.
ABSTRACT A 50‐year‐old female patient was referred to our department for consultation regarding perioperative management of breast cancer surgery. She had a history of photosensitivity since childhood and was diagnosed with erythropoietic protoporphyria (EPP) during her first pregnancy.

Clinical evaluation of a method for detecting superficial transitional cell carcinoma of the bladder by light-induced fluorescence of protoporphyrin IX following topical application of 5-aminolevulinic acid: Preliminary results

open access: yes, 1997
BACKGROUND AND OBJECTIVE: In bladder cancer, conventional white light endoscopic examination of the bladder does not provide adequate information about the presence of "flat" urothelial lesions such as carcinoma in situ.
