AI Article Synopsis

  • The study examined how different stages of erythrocyte maturity and their quantities affect erythropoiesis in cultured erythroblastic islands.
  • It was found that both the amount and the maturity of erythrocytes have a dose-dependent and maturity-dependent inhibitory effect on the formation of erythroblastic islands.
  • Additionally, erythrocytes from polycythemic rats were shown to inhibit the maturation and formation of these islands more effectively compared to erythrocytes from normal or anemic rats.

Article Abstract

Comparison of influence of erythrocytes of different stages of maturity, and their amount on erythropoiesis in erythroblastic island culture revealed their dose-dependent and maturity-dependent inhibiting effect on erythropoiesis. Erythrocytes of polycythemic rats inhibit maturing and formation of erythroblastic islands more intensively than erythrocytes of normal on anemic rats.

Background/objectives: Iron-fortified foods reduce the incidence of iron deficiency anemia. However, the nutritional efficacy of heme iron fortificants is unclear.

Methods: In this study, we determined the hemoglobin regeneration efficiency (HRE) of a porcine-derived heme iron powder (HIP), treating anemic rats (hemoglobin (Hb) 3-6 g/dL) with 14-day repletion diets fortified with four different concentrations (12, 24, 36, or 48 mg iron/kg diets) of HIP or a control diet ("no added iron"); = 9-12/group.

Purpose: To demonstrate the feasibility of measuring pulmonary hematocrit (Hct) in blood in vivo using oscillation of hyperpolarized Xe MR signals and its potential for disease assessment in animal models.

Methods: Hyperpolarized Xe dynamic MR spectroscopy was performed on 10 anemia model rats and 10 control rats. A concise model based on hyperpolarized Xe MR signal oscillations was built for calculating pulmonary Hct.

Article Synopsis
  • Phlebotomy-induced-anemia (PIA) in neonatal rats is examined for its effects on retinopathy of prematurity (ROP), revealing that PIA may actually decrease the severity of the condition rather than worsen it as initially hypothesized.* -
  • In the study, PIA resulted in a significant decrease in avascular and neovascular areas of the retina, as well as lower levels of several pro-inflammatory cytokines at key developmental stages (P15 and P20).* -
  • Findings suggest that anemia has a protective effect against pathological retinal changes in ROP, influencing gene expression and molecular pathways associated with angiogenesis and inflammation, with notable differences observed based on the sex of the subjects.*

Iron deficiency (ID) is common during gestation and in early infancy and has been shown to adversely affect cardiac development and function, which could lead to lasting cardiovascular consequences. Ketone supplementation has been shown to confer cardioprotective effects in numerous disease models. Here, we tested the hypothesis that maternal ketone supplementation during gestation would mitigate cardiac dysfunction in ID neonates.
