Isolation and characterisation of mesenchymal stem cells from rat bone marrow and the endosteal niche: A comparative study [PDF]

open access: yes, 2018
Within bone, mesenchymal stromal cells (MSCs) exist within the bone marrow stroma (BM-MSC) and the endosteal niche, as cells lining compact bone (CB-MSCs).

Mutarotation of tetramethylglucose catalyzed by ribonucleosides

open access: yesTetrahedron Letters, 1997
Abstract The inherent catalytic ability of various 2′, 3′, 5′ tri-OTBS protected RNA nucleosides in facilitating mutarotation of tetramethylglucose in benzene was investigated. Nucleosides A, G, and Ψ showed modest rate enhancements (3–5 fold) over the uncatalyzed rate whereas C demonstrated a rate increase of over 20-fold.

The wider perspective: Barriers and recommendations for transfusion support for patients with sickle cell disease in low‐ and middle‐income countries

open access: yesBritish Journal of Haematology, Volume 206, Issue 6, Page 1585-1592, June 2025.
Globally, sickle cell disease (SCD) is the most common inherited haemoglobinopathy. The highest burden of SCD is encountered in low‐ and middle‐income countries (LMICs), most of which lack the resources to contend with the disease. Blood transfusion remains central to the emergent treatment and prevention of complications of SCD.

Purine and pyrimidine antagonism in a pyrimidine-deficient mutant of Neurospora [PDF]

open access: yes, 1948
The present study is concerned with the inhibition of growth of the pyrimidine-deficient Neurospora mutant, No. 1298, by the naturally occurring purine ribonucleotides and ribonucleosides.

miR‐486‐5p Inhibits eNOS and Angiogenesis in Cultured Endothelial Cells by Targeting MAML3

open access: yesJournal of Cellular and Molecular Medicine, Volume 29, Issue 11, June 2025.
ABSTRACT Kidney ischemia–reperfusion (I/R) is associated with endothelial injury. Administration of miRNA (miR)‐486‐5p protects against rat kidney I/R injury, with localisation to capillary endothelial cells, although it inhibits I/R‐induced endothelial nitric oxide synthase (eNOS) protein expression.
