Understanding extracellular vesicles in antiaging

Periodontology 2000, EarlyView.
Abstract Background Aging is a multifactorial process marked by gradual cellular dysregulation, regulated by hallmarks, including genomic instability, mitochondrial dysregulation, and chronic inflammation. Extracellular vesicles (EVs), especially exosomes, have emerged as pivotal mediators of cell‐to‐cell communication with potential roles in both ...

Massive fetomaternal hemorrhage and successful prevention of maternal RhD alloimmunization: A case report

Transfusion, EarlyView.
Abstract Background Massive fetomaternal hemorrhage can lead to significant fetal morbidity or mortality. RhD negative patients require appropriate treatment to prevent alloimmunization in subsequent pregnancies. Few cases with follow‐up into future pregnancies have been reported.

Hepatitis B virus infection with high HBsAg and undetectable DNA levels in untreated blood donors: Viral mechanisms and transfusion safety implications

Transfusion, EarlyView.
Abstract Background Blood donor screening occasionally identifies individuals with high HBV surface antigen (HBsAg) levels despite undetectable or extremely low HBV DNA. Molecular basis and transfusion risk of this discordant profile remain unclear. Study Design and Methods Seventy‐five blood donors with HBsAg >100 IU/mL and undetectable or very low ...

Comparing the volume of umbilical cord blood collection using different techniques

Vox Sanguinis, EarlyView.
Abstract Background and Objectives Umbilical cord blood (UCB) as a source for red blood cell (RBC) transfusions is a promising alternative to adult RBC transfusions in extremely preterm neonates, as UCB contains predominantly fetal haemoglobin (HbF). A limitation to clinical use is the low and variable yield of UCB collections.

Leptin–cholesterol crosstalk in pregnancy: Mechanistic implications for placental function and cardiometabolic programming

Experimental Physiology, EarlyView.
Abstract Pregnancy requires the coordinated maternal reorganization of lipid and endocrine pathways to sustain fetal growth and anticipate neonatal nutrition. Leptin, produced by adipose tissue and the placenta, acts as an integrative signal linking maternal energy status with trophoblast function and vascular adaptation, while cholesterol provides ...

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Born early, age fast: Consequences of premature birth on chronic disease and accelerated ageing

The Journal of Physiology, EarlyView.
Abstract figure legend ELGANs are exposed to several postnatal pro‐oxidant stressors, including ambient and supplemental oxygen, mechanical ventilation, infections, hyperalimentation, excessive glucocorticoids and intermittent hypoxia. Since endogenous antioxidant defences are underdeveloped, this imbalance promotes oxidative stress and inflammation ...

Cannabinoid exposure during pregnancy: Cardiorespiratory effects and offspring outcomes

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to cannabinoids has been investigated across human and animal studies to understand its impact on physiological development. Evidence suggests that early‐life cannabinoid exposure influence multiple developmental processes, extending beyond neurodevelopmental outcomes to potentially affect placental function ...

Human placental exposure to pollutant nanoparticles: uptake, translocation and functional impact

The Journal of Physiology, EarlyView.
Abstract figure legend Prenatal exposure to pollutant nanoparticles has been increasingly investigated due to concerns about their potential effects on placental function and pregnancy outcomes. Maternal inhalation of pollutant nanoparticles can result in a pro‐inflammatory response; particles can also translocate across the alveolus epithelial barrier

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

The Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...
