Trends in Utilization of Common Tests and Procedures in Treating PAD in the Medicare Population from 2011 to 2021.

This study investigated changes in utilization of diagnostic imaging-CT angiography (CTA) and MR angiography (MRA)-and treatments-stent placement, angioplasty, atherectomy, and bypass-in PAD across different physician specialties and healthcare facilities from 2011-2021. Data were gathered from the 2011-2021 Physician/Supplier Procedure Summary files and tallied per 100,000 Medicare beneficiaries. Sites of service included inpatients, physician offices, and hospital outpatient departments.

The Typical tRNA Co-Expresses Multiple 5' tRNA Halves Whose Sequences and Abundances Depend on Isodecoder and Isoacceptor and Change with Tissue Type, Cell Type, and Disease.

Transfer RNA-derived fragments (tRFs) are noncoding RNAs that arise from either mature transfer RNAs (tRNAs) or their precursors. One important category of tRFs comprises the tRNA halves, which are generated through cleavage at the anticodon. A given tRNA typically gives rise to several co-expressed 5'-tRNA halves (5'-tRHs) that differ in the location of their 3' ends.

TET-Mediated Epigenetic Regulation in Immune Cell Development and Disease.

TET proteins oxidize 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC) and further oxidation products in DNA. The oxidized methylcytosines (oxi-mCs) facilitate DNA demethylation and are also novel epigenetic marks. TET loss-of-function is strongly associated with cancer; loss-of-function mutations are frequently observed in hematological malignancies that are resistant to conventional therapies.
