1. Macrophages: key players in erythrocyte turnover
ABSTRACT The development of red blood cells (RBCs), or erythropoiesis, occurs in specialized niches in the bone marrow, called erythroblastic islands, composed of a central macrophage surrounded by erythroblasts at different stages of differentiation. Upon anemia or hypoxemia, erythropoiesis extends to extramedullary sites, mainly spleen and liver, a process

2. Chronic transfusion therapy effectiveness as primary stroke prophylaxis in sickle cell disease patients
Abstract Introduction About 10% of sickle cell anemia patients will have ischemic stroke. Adams showed stroke incidence reduction in children receiving monthly erythrocyte transfusions by reducing transcranial Doppler (TCD) velocities. Since then, chronic transfusion is recommended as primary stroke prophylaxis. This study aims to assess the effectiveness o

3. Toxicological evaluation of Lafoensia pacari A. St.-Hil. (Lythraceae) stem bark extract: Acute and subchronic studies in mice
This study evaluated the safety of Lafoensia pacari A. St.-Hil. (Lythraceae) stem bark hydroalcoholic extract (LPE) through acute and subchronic toxicological assessments in mice. In the acute toxicity evaluation, a single 2000 mg/kg oral dose of LPE was administered to mice and clinical observations were conducted for 14 days. For subchronic toxicity, LPE d

4. Correlação entre as contagens de reticulócitos manual e automática em amostras de felinos anêmicos
RESUMO O objetivo do presente estudo foi correlacionar os valores de reticulócitos pontilhados e agregados obtidos por metodologia manual com a metodologia automática de contagem de reticulócitos totais em amostras de sangue de gatos anêmicos, analisados em um contador hematológico com citometria de fluxo. Para isso, 40 amostras de sangue de pacientes f

5. In vitro kinetics of reticulocyte subtypes: maturation after red blood cell storage in additive solution-1 (AS-1)
ABSTRACT Background: Reticulocytes are immature red blood cells containing RNA remnants. Their population kinetics has been documented under various in vivo and in vitro conditions, including after storage of red blood cells in blood banks. The purpose of this study was to describe the influence of blood bank storage on the kinetics of reticulocyte disappea

7. Foxo3 gene expression and oxidative status in beta-thalassemia minor subjects
ABSTRACT Background: Oxidative stress may aggravate symptoms of hemolytic anemias such as beta-thalassemia. FoxO3 activation results in resistance to oxidative stress in fibroblasts and neuronal cell cultures. Objective: The purpose of this research was to study FoxO3 gene expression and oxidative status in beta-thalassemia minor individuals. Methods: Six

8. Determination of reference ranges for immature platelet and reticulocyte fractions and reticulocyte hemoglobin equivalent
ABSTRACT Introduction: The immature platelet and immature reticulocyte fractions represent the ratios of platelets and reticulocytes recently released into the circulation and thus with higher RNA content. They are considered early indicators of bone marrow recovery. Objective: The aim of this study was to determine the reference ranges for the immature pl

9. Genotoxicity Evaluation of Dipotassium -Trioxohydroxytetrafluorotriborate, K2(B3O3F4OH), in Human Lymphocyte Cultures and Mice Reticulocytes
ABSTRACT Genotoxic effects of inorganic molecule dipotassium-trioxohydroxytetrafluorotriborate, K2(B3O3F4OH), a promising new therapeutic for the epidermal changes treatment, have been evaluated. In vitro analysis included evaluation of genotoxic and cytotoxic potential of K2(B3O3F4OH) in concentrations of 0.01, 0.02, 0.05 and 0.06 mg/mL applying cytokinesis

10. Assessment of blood sample stability for complete blood count using the Sysmex XN-9000 and Mindray BC-6800 analyzers
ABSTRACT BACKGROUND: Different hematological analyzers have different analytical performances that are often reflected in the criteria for sample stability of the complete blood count. This study aimed to assess the stability of several hematological parameters using the XN-9000 Sysmex and BC-6800 Mindray analyzers. METHODS: The impact of storage at room

11. Clinical, hematological and genetic data of a cohort of children with hemoglobin SD
ABSTRACT INTRODUCTION: The hemoglobin FSD is very uncommon in newborn screening programs for sickle cell disease. In the program of Minas Gerais, Brazil, the clinical course of children with hemoglobin SD was observed to be heterogeneous. The objective of this study was to estimate the incidence (1999-2012) and to describe the natural history of a cohort o

12. Evaluation of erythrocyte and reticulocyte parameters as indicative of iron deficiency in patients with anemia of chronic disease
Objective: The aim of this study was to evaluate the effectiveness of mature red cell and reticulocyte parameters to identify three conditions: iron deficiency anemia, anemia of chronic disease, and anemia of chronic disease associated with absolute iron deficiency. Methods: Peripheral blood cells from 117 adult patients with anemia were classified accord-
