[Fetal hemoglobin].

Postepy higieny i medycyny doswiadczalnej, 1991
The paper presents a current state of knowledge on the regulation of Hb synthesis in physiology and pathology. Possible mechanisms of HbF synthesis switching and an influence of different drugs on HbF production have been described.

Effect of Ultraviolet Irradiation on Hemoglobin Oxidation [PDF]

, 1987
The autoxidation of hemoglobin was markedly increased when the solution of hemoglobin was irradiated by ultraviolet (UV) ray under aerobic conditions. The oxidation of hemoglobin was not observed when hemoglobin was irradiated with UV ray under anaerobic

Intranasal Delivery of Gallium–Quercetin Nanoparticles for Multi‐Target Ferroptosis Inhibition in Parkinson's Disease

Advanced Science, EarlyView.
Leveraging the chemical similarity between Ga3+ and Fe3+ as well as the antioxidant properties of quercetin, gallium–quercetin nanoparticles (GQNPs) were prepared to integrate iron homeostasis regulation, oxidative stress suppression, and mitochondrial protection for multi‐target ferroptosis inhibition in Parkinson's Disease.

The Ag-195 (C®G) mutation in hereditary persistence of fetal hemoglobin is not associated with activation of a reporter gene in vitro

Brazilian Journal of Medical and Biological Research, 2001
Hereditary persistence of fetal hemoglobin is an uncommon, benign disorder in which the expression of gamma-globin genes persists into adult life. Several point mutations have been associated with the increased gamma-globin gene promoter activity.

Metabolic Reprogramming in Glioblastoma Stem Cells Promotes Radiation Resistance Through a H3K18la/USP30/MBOAT2 Axis

Advanced Science, EarlyView.
LDHA‐driven lactate production in mesenchymal glioma stem cells promotes p300‐dependent H3K18 lactylation, activates USP30 transcription, and stabilizes MBOAT2 to remodel phosphatidylethanolamines toward ferroptosis‐resistant PE‐MUFA species. Disrupting this metabolic–epigenetic–lipid circuit enhances ferroptosis and sensitizes glioblastoma to ...

Blood Cell‐Camouflaged Liquid Metal Nanoconjugates Orchestrate Treg Depletion and STING‐Amplified Photothermal Immunity for Metastatic Triple‐Negative Breast Cancer Therapy

Advanced Science, EarlyView.
Whole‐blood biomimetic engineering transforms liquid metal nanoparticles into a tripartite immunotherapeutic platform that orchestrates regulatory T‐cell depletion, photothermal‐induced immunogenic cell death, and activation of the stimulator of interferon genes pathway.

Assessing maternal and perinatal complication incidence in pregnant patients with sickle cell disease: a retrospective analysis of transfusion therapy at a tertiary care hospital

Frontiers in Hematology
BackgroundPregnant individuals with sickle cell disease (SCD) face high maternal and fetal complication rates. While some studies suggest transfusions may improve outcomes, evidence is limited.

Polystyrene Nanoplastics Drive β‐Cell Dedifferentiation Through Dendritic Cell‐Intrinsic MHC‐I‐Dependent Inflammatory Crosstalk

Advanced Science, EarlyView.
Polystyrene nanoplastics disrupt pancreatic immune–endocrine homeostasis by promoting MHC‐I‐associated dendritic cell activation and inflammatory crosstalk with β cells. This immune remodeling drives β‐cell dedifferentiation, impairs insulin secretion, and aggravates metabolic dysfunction, revealing a previously unrecognized immunometabolic mechanism ...

Rapid fetal hemoglobin estimation assay during cordocentesis

, 1994
A method for rapid estimation of fetal blood content during cordocentesis is described. This procedure gives an opportunity to determine the contamination of the fetal sample by maternal blood as soon as possible.
