Meteorin-like protein plasma levels are associated with worse outcomes in de novo heart failure.

Background And Aims: Meteorin-like protein (Metrnl) has been recently suggested as a new adipokine with protective cardiovascular effects. Its circulating levels in patients seem to be associated with heart failure (HF), although with contradictory results. Our aim was to ascertain whether this adipokine could estimate the prognosis of HF in de novo HF (DNHF) patients.

Bone regeneration in sheep model induced by strontium-containing mesoporous bioactive glasses.

Local delivery of therapeutic ions from bioactive mesoporous glasses (MBGs) is postulated as one of the most promising strategies for regenerative therapy of critical bone defects. Among these ions, Sr cation has been widely considered for this purpose as part of the composition of MBGs. MBGs of chemical composition 75SiO-25-x CaO-5PO-xSrO with x = 0, 2.

Emerging role of circulating piRNAs in the diagnosis of heart transplant rejection.

Background: Liquid biopsy offers a potential alternative to decrease or eliminate endomyocardial biopsy for diagnosing allograft rejection. p-element-induced wimpy testis-interacting RNAs (piRNAs) are novel and promising disease biomarkers for their intrinsic characteristics such as stability in body fluids; however, their role in allograft rejection remains unexplored.

Methods: A training set based on small RNA sequencing technology was performed to identify piRNAs in endomyocardial tissue (n = 8) and serum samples (n = 40) from patients following heart transplantation.

Metabolomic characterization of MC3T3-E1pre-osteoblast differentiation induced by ipriflavone-loaded mesoporous nanospheres.

This study reports on the metabolic changes accompanying the differentiation of MC3T3-E1 osteoprogenitor cells induced by mesoporous bioactive glass nanospheres (nMBG) loaded with ipriflavone (nMBG-IP). Ipriflavone (IP) is a synthetic isoflavone known for inhibiting bone resorption, maintaining bone density, and preventing osteoporosis. Delivering IP intracellularly is a promising strategy to modulate bone remodeling at significantly lower doses compared to free drug administration.

Transcriptomic Alterations in Spliceosome Components in Advanced Heart Failure: Status of Cardiac-Specific Alternative Splicing Factors.

Heart failure (HF) is associated with global changes in gene expression. Alternative mRNA splicing (AS) is a key regulatory mechanism underlying these changes. However, the whole status of molecules involved in the splicing process in human HF is unknown.
