The Ag-195 (C®G) mutation in hereditary persistence of fetal hemoglobin is not associated with activation of a reporter gene in vitro

open access: yesBrazilian Journal of Medical and Biological Research, 2001
Hereditary persistence of fetal hemoglobin is an uncommon, benign disorder in which the expression of gamma-globin genes persists into adult life. Several point mutations have been associated with the increased gamma-globin gene promoter activity.

Microglia‐Targeted Biomimetic Tetrahedral Framework Nucleic Acid Nanovesicles for Synergistic Treatment of Sepsis‐Associated Encephalopathy

open access: yesAdvanced Science, EarlyView.
Sepsis‐associated encephalopathy (SAE) lacks effective therapies. We developed ME@FDsi, a biomimetic nanodrug using a tetrahedral framework nucleic acid to deliver disulfiram and siTNFα. It crosses the blood‐brain barrier, targets M1 microglia, inhibits pyroptosis and inflammation, and scavenges ROS.

Copper Depletion Nanoparticles Potentiate Cancer Immunotherapy by Avoiding Innate and Adaptive Immune Resistance

open access: yesAdvanced Science, EarlyView.
A mitochondria‐targeted copper depletion nanoplatform (CYN‐CDA@Alb) was developed to selectively disrupt tumor mitochondria copper, which then reprogrammed the tumor immune microenvironment by depressing PD‐L1 and CD47 expression simultaneously. By doing this, CYN‐CDA@Alb reversed radiotherapy‐induced immune tolerance, showing the potential usage of ...

Assessing maternal and perinatal complication incidence in pregnant patients with sickle cell disease: a retrospective analysis of transfusion therapy at a tertiary care hospital

open access: yesFrontiers in Hematology
BackgroundPregnant individuals with sickle cell disease (SCD) face high maternal and fetal complication rates. While some studies suggest transfusions may improve outcomes, evidence is limited.

Senp1 drives hypoxia-induced polycythemia via GATA1 and Bcl-xL in subjects with Monge's disease. [PDF]

open access: yes, 2016
In this study, because excessive polycythemia is a predominant trait in some high-altitude dwellers (chronic mountain sickness [CMS] or Monge's disease) but not others living at the same altitude in the Andes, we took advantage of this human experiment ...

Design of Single‐Atom Nanozymes for Precision Treatment of Erectile Dysfunction with Integrated Single‐Cell RNA Sequencing and Machine Learning

open access: yesAdvanced Science, EarlyView.
It is innovatively utilized single‐cell RNA sequencing to explore the underlying causes of diabetes mellitus‐induced erectile dysfunction, followed by machine learning‐driven design of a single‐atom nanozyme (Fe‐DMOF) for precision treatment of erectile dysfunction.

Development of a new staining protocol for the Kleihauer–Betke test to facilitate the reading of difficult cases

open access: yesBMC Pregnancy and Childbirth
Background The Kleihauer–Betke (KB) test allows the detection of fetal red blood cells (containing fetal hemoglobin, HbF) in the maternal blood to identify and quantify potential fetal-maternal hemorrhages.

Vimentin downregulation is an inherent feature of murine erythropoiesis and occurs independently of lineage [PDF]

open access: yes, 1990
In mammalian erythropoiesis, the mature cells of the primitive lineage remain nucleated while those of the definitive lineage are anuclear. One of the molecular and structural changes that precedes enucleation in cells of the definitive lineage is the ...

Senomorphic Small Extracellular Vesicles Delivered by a Tissue‐Adhesive α‐Lipoic‐Acid Hydrogel Enable Immuno‐Rejuvenation for Bone‐Tendon Interface Regeneration

open access: yesAdvanced Science, EarlyView.
This work identifies M1 macrophage‐mediated inflammation as a key driver of BMSC senescence and bone microstructural deterioration at the enthesis. A tissue‐adhesive hydrogel delivering senomorphic small extracellular vesicles suppresses this inflammatory‐senescent cascade and enhances BMSC resilience by inhibiting the cGAS‐STING‐NF‐κB pathway.
