We have succeeded in synthesis of gold nanoparticles (Au NPs) on the interior surfaces of red blood cell ghosts (RBCGs) with a cytoskeleton chemically conjugated to a gold-binding peptide. The Au NP-deposited RBCG with the peptide exhibits enhanced catalytic reactivity for the reduction of 4-nitrophenol due to the uniform distribution of the Au NPs on the inner surface and the coverage of the Au NPs surface with the peptide.

Effect of iron fortification and prebiotics on iron biomarkers in anemic rats.

One of the biggest public health problems globally is that of iron deficiency anemia. The present research aimed to determine the effect of prebiotics along with iron fortification on iron biomarkers in female anemic rats as some evidence suggests that prebiotics convert increase the solubility of iron, thereby enhancing its absorption. A total of 126 Sprague Dawley rats were fed with sixteen different types of fortified feed containing prebiotics (Inulin + Galacto Oligosaccharides) and Iron Fortificants (Sodium Ferric Ethylenediaminetetraacetate + Ferrous Sulphate).

Erythropoiesis, a remarkably dynamic and efficient process responsible for generating the daily quota of red blood cells (approximately 280 ± 20 billion cells per day), is crucial for maintaining individual health. Any disruption in this pathway can have significant consequences, leading to health issues. According to the World Health Organization, an estimated 25% of the global population presents symptoms of anemia.

Hemolytic anemia (HA) is characterized by massive destruction of red blood cells (RBCs) and insufficient oxygen supply, which can lead to shock, organ failure, even death. Recent studies have preliminarily demonstrated the therapeutic effectiveness of whole blood exchange (WBE) in the management of acute hemolytic anemia and exhibited potential for reducing the duration of corticosteroid treatment, while the underlying mechanism of WBE therapy was not investigated in preclinical study. Hence, we investigate the therapeutic mechanisms of WBE in HA through established continued WBE therapy in rats creatively.

Background: Tranexamic acid is an anti-fibrinolytic agent routinely used during hip and knee joint replacement surgery to minimize bleeding. Chronic kidney disease is a common chronic health problem seen among adults requiring major arthroplasty surgery. Tranexamic acid is renally cleared and may accumulate in chronic kidney disease.

Background: Hemoglobin (Hb) Hekinan is a prevalent α-globin variant frequently missed in thalassemia screening centers using high-performance liquid chromatography (HPLC) or capillary electrophoresis. This study aims to investigate the hematological and molecular characteristics of Hb Hekinan in a large cohort.
Methods: Hb variants were identified using isoelectric focusing (IEF) and HPLC.
