Stenting of native coronary arteries with a balloon-expandable stent was attempted in 226 patients after elective angioplasty. Delivery the device successful 213 (94%) patients. Of these, 39 received aspirin and dipyridamole only (group 1) 174 aspirin, dipyridamole, warfarin for 1-3 months 2). There no abrupt closure (less than or equal to 1 day) perioperative death either group. In-hospital complications group compared 2 were as follows: subacute (1-14 days), seven (18%) versus one (0.6%)...

The success of tyrosine kinase inhibitors (TKIs) in treating chronic myeloid leukemia (CML) depends on the requirement for BCR-ABL1 activity CML progenitors. However, quiescent HSCs are TKI resistant and represent a kinase-independent disease reservoir. Here we have shown that persistence leukemic BM requires inhibition tumor suppressor protein phosphatase 2A (PP2A) expression--but not activity--of oncogene. Examination from patients healthy individuals revealed PP2A was suppressed compared...

Dorsal root ganglia (DRG) somatosensory neurons detect mechanical, thermal, and chemical stimuli acting on the body. Achieving a holistic view of how different DRG neuron subtypes relay neural signals from periphery to CNS has been challenging with existing tools. Here, we develop curate mouse genetic toolkit that allows for interrogating properties functions distinct cutaneous targeting subtypes. These tools have enabled broad morphological analysis, which revealed axon arborization areas...

BACKGROUND Several metallic intracoronary stents are currently undergoing preliminary evaluation to ascertain potential benefit as means reduce the 30-40% incidence of restenosis after balloon angioplasty. METHODS AND RESULTS To determine and correlates placement Palmaz-Schatz in native coronary arteries first group patients selected for this procedure, clinical quantitative angiographic data from 206 consecutive (221 stenoses) with successful stent (diameter stenosis < 50%) were...

Long non-coding RNAs (lncRNAs) are important regulatory molecules that implicated in cellular physiology and pathology. In this work, we dissect the functional role of HOXB-AS3 lncRNA patients with NPM1-mutated (NPM1mut) acute myeloid leukemia (AML). We show regulates proliferative capacity NPM1mut AML blasts vitro vivo. is shown to interact ErbB3-binding protein 1 (EBP1) guide EBP1 ribosomal DNA locus. Via mechanism, RNA transcription de novo synthesis. propose context NPM1 mutations,...

Balanced rearrangements involving the KMT2A gene, located at 11q23, are among most frequent chromosome aberrations in acute myeloid leukemia (AML). Because of numerous fusion partners, mutational landscape and prognostic impact specific 11q23/KMT2A not fully understood. We analyzed clinical features 172 adults with AML recurrent rearrangements, 141 whom had outcome data available. compared outcomes these patients 1,097 without an rearrangement categorized according to 2017 European...

Summary Mechanical and thermal stimuli acting on the skin are detected by morphologically physiologically distinct sensory neurons of dorsal root ganglia (DRG). Achieving a holistic view how this diverse neuronal population relays information from to central nervous system (CNS) has been challenging with existing tools. Here, we used transcriptomic datasets mouse DRG guide development curation genetic toolkit interrogate transcriptionally defined neuron subtypes. Morphological analysis...

To date, limited evidence is available specifically evaluating ridge preservation (RP) and implant placement in molar sites. The primary aim of this study to radiographically compare alveolar changes with without RP cone-beam computed tomography (CBCT).This parallel, two-arm randomized clinical trial included 40 patients evenly distributed between two treatment groups. After extraction, sites were allowed heal naturally or received freeze-dried bone allograft covered by a non-resorbable...
