Acquired spherocytosis in the setting of myelodysplasia

Leukemia Research Reports, 2022
Hereditary spherocytosis (HS) is the most prevalent red blood cell (RBC) membrane disorder. We report a rare case of acquired SPTB spherocytosis coinciding with a myelodysplastic syndrome associated U2AF1 mutation, neither found in germline DNA.

Parvovirus B19 infection in pediatric transplant patients [PDF]

, 1993
Evidence of recent parvovirus virus infection (as determined by the presence of a positive IgM antibody titer) without other identified causes of anemia was found in 5 of 26 pediatric solid-organ transplant recipients evaluated for moderate-to-severe ...

Active Force Dynamics in Red Blood Cells Under Non‐Invasive Optical Tweezers

Advanced Science, Volume 13, Issue 10, 18 February 2026.
A non‐invasive method combines low‐power optical tweezers with high‐speed microscopy to simultaneously monitor local membrane forces and displacements in single human red blood cells. This dual‐channel approach reveals a mechano‐dynamic signature that correlates the cell's metabolic state with its mechanical activity. This energetic framework serves as

Targeted Next‐Generation Sequencing of the Leptin‐Melanocortin Pathway in Severe Obesity

Obesity, Volume 34, Issue 2, Page 499-511, February 2026.
ABSTRACT Objective Pathogenic variants in five established leptin‐melanocortin pathway genes (LEP, LEPR, MC4R, PCSK1, POMC) are associated with severe early‐onset obesity and are targets for emerging treatments. However, these variants are rare in these patients, suggesting the involvement of additional genes interacting with this pathway. Methods Next‐

Identification of a De Novoc.1000delA ANK1 mutation associated to hereditary spherocytosis in a neonate with Coombs-negative hemolytic jaundice-case reports and review of the literature

BMC Medical Genomics, 2021
Background To strengthen the understanding of Hereditary Spherocytosis (HS) and determine the disease-causing mutation present with neonatal jaundice. HS is a hemolytic condition resulting from various erythrocyte membrane defects.

Coexistence of congenital red cell pyruvate kinase and band 3 deficiency [PDF]

, 2003
The authors report the case of a 9-year-old Caucasian girl, born in northern Portugal, with chronic nonspherocytic haemolytic anaemia and without family history of anaemia. The aethiological study of this anaemia revealed pyruvate kinase deficiency (PKD),

Across species: A comparative perspective on red cell homeostasis and its influence on our understanding of human physiology and disease

British Journal of Haematology, Volume 208, Issue 2, Page 446-458, February 2026.
This review highlights how studies on animal red cells have enriched our understanding of the behaviour of those from humans. A comparative perspective has enhanced our knowledge of human red cell pathophysiology Summary This review emphasises how studies on animal red cells have enriched our understanding of the behaviour of those from humans.
