Flow cytometric test for analyzing the eosin-5-maleimide (EMA) binding to red blood cells has been believed to be a specific method for diagnosing hereditary spherocytosis (HS). However, it has been reported that diseases other than HS, such as hereditary pyropoikilocytosis (HPP) and Southeast Asian ovalocytosis (SAO), which are forms in the category of hereditary elliptocytosis (HE), show decreased EMA binding to red blood cells. We analyzed EMA binding to red blood cells in 101 healthy control subjects and 42 HS patients and obtained a mean channel fluorescence (MCF) cut-off value of 36.4 (sensitivity 0.97, specificity 0.95). Using this method, we also analyzed 12 HE patients. Among them, four HE patients showed the MCF at or below the cut-off value. It indicates that some HE patients have decreased EMA binding to red blood cells. Two of these four HE patients were classified as common HE, and two were spherocytic HE with reduced spectrin. This study demonstrates that, in addition to patients with HPP or SAO, some HE patients have decreased EMA binding to red blood cells.

The FIKK protein family, encompassing 21 serine-threonine protein kinases, is a distinctive cluster exclusive to the Apicomplexa phylum. Predominantly located in which is a malarial parasite, with a solitary gene identified in a distinct apicomplexan species, this family derives its nomenclature from - phenylalanine, isoleucine, lysine, lysine (FIKK), a conserved amino acid motif. Integral to the parasite's life cycle and consequential to malaria pathogenesis, the absence of orthologous proteins in eukaryotic organisms designates it as a promising antimalarial drug target.

Background: Necrotising enterocolitis (NEC) is life-threatening with a rising incidence due to improved neonatal care. While researchers' focus has shifted to causes, risk factors and preventative clinical strategies, little is known about the exact aetiology of NEC. Risk factors include the relationship between red blood cell transfusions (RBCTs) and the development of transfusion-associated NEC (TANEC) and peri-transfusion feeding, increasing the risk of TANEC.

Due to global blood shortages and restricted donor blood storage, the focus has switched to the in vitro synthesis of red blood cells (RBCs) from induced pluripotent stem cells (iPSCs) as a potential solution. Many processes are required to synthesize RBCs from iPSCs, including the production of iPSCs from human or animal cells, differentiation of iPSCs into hematopoietic stem cells, culturing, and maturation of the hematopoietic stem cells (HSC) to make functional erythrocytes. Previous investigations on the in vitro production of erythrocytes have shown conflicting results.

Thrombotic microangiopathies (TMA) are a group of conditions that present with varying degrees of microthrombi, thrombocytopenia, microangiopathic hemolytic anemia, renal dysfunction, and neurological impairment. Etiologies can be primary, such as thrombotic thrombocytopenic purpura (TTP), hemolytic uremic syndrome (HUS), and atypical hemolytic uremic syndrome (aHUS), or secondary, such as due to systemic infections, malignancies, immune-mediated conditions, and hypertensive emergencies. In hypertensive emergencies, this presentation can occur from mechanical stress placed on red blood cells as they pass through narrowed arteries due to edema and microangiopathic changes within the vessels themselves.

Background: The erythrocyte sedimentation rate (ESR) is a widely used haematological test that indirectly measures inflammation in the body. It is influenced by various factors, including age, sex, and physiological condition. Altitude is another critical factor due to its impact on red blood cell physiology and plasma protein composition.
