The metabolism of cells and blood circulation allow for the constant production and destruction of red blood cells. Erythrocyte formation allows red blood cells to regenerate, which is crucial for maintaining the equilibrium of the organism. Erythrocyte formation is a multi-step, intricate process with distinct structural and functional characteristics at each stage. Erythropoiesis is regulated by a number of signaling pathways; malfunctional regulatory mechanisms may result in disease and aberrant erythropoiesis. Therefore, this article focuses on a review of the erythroid formation process, related signaling pathways, and red blood cell lineage diseases.

Biopreservation and reversal of oxidative injury during blood storage by a novel curcumin-based gel formulation.
Sci Rep

Blood storage lesion induces cytosolic and membrane changes driven in part by hemoglobin (Hb) oxidation reactions within red blood cells (RBCs). A novel gel formulation containing the antioxidant curcuminoids in a biocompatible solvent system was used to deliver curcumin into RBCs. Incubation of peroxide treated RBCs stored in PBS with curcumin gel led to a reduction in prooxidant ferrylHb and recovery in ATP.

Background: Hematological markers such as the neutrophil-lymphocyte ratio (NLR), monocyte-lymphocyte ratio (MLR), and platelet-lymphocyte ratio (PLR) are reliable indicators of inflammation. This study aims to investigate the potential role of these markers in assessing disease activity and treatment response in biologic-naive Ankylosing Spondylitis (AS) patients following the initiation of biological agents.
Materials And Methods: We designed this study as a retrospective cohort study with data obtained from a single center.
Uncovering metabolic dysregulation in schizophrenia and cannabis use disorder through untargeted plasma lipidomics.

Cannabis use disorder affects up to 42% of individuals with schizophrenia, correlating with earlier onset, increased positive symptoms, and more frequent hospitalizations. This study employed an untargeted lipidomics approach to identify biomarkers in plasma samples from subjects with schizophrenia, cannabis use disorder, or both (dual diagnosis), aiming to elucidate the metabolic underpinnings of cannabis abuse and schizophrenia development. The use of liquid chromatography-high resolution mass spectrometry enabled the annotation of 119 metabolites, with the highest identification confidence level achieved for 16 compounds.

Antiphospholipid syndrome (APS) is associated with recurrent pregnancy morbidity, yet the underlying mechanisms remain elusive. We performed multifaceted characterization of the biological and transcriptomic signatures of mouse placenta and uterine natural killer (uNK) cells in APS. Histological analysis of APS placentas unveiled placental abnormalities, including disturbed angiogenesis, occasional necrotic areas, fibrin deposition, and nucleated red blood cell enrichment.
