Lollipop and Lariat Symmetric Functions
We compute an explicit e-positive formula for the chromatic symmetric function of a 3 lollipop graph, Lm,n. From here we deduce that there exist countably infinite distinct e-positive, and 4 hence Schur-positive, bases of the algebra of symmetric functions whose generators are chromatic 5 symmetric functions. Finally, we resolve 6 conjectures on the chromatic symmetric function of a 6 lariat gr...
متن کاملDeoxyribozymes that synthesize branched and lariat RNA.
Branched RNA molecules with a 2',5'-phosphodiester linkage are important biochemical intermediates. Lariat RNA is a particular type of branched RNA that is formed during intron splicing in vivo. Synthesis of branched and lariat RNA is challenging, and there are few general approaches that are applicable in vitro. Here we report the identification of divalent metal-dependent deoxyribozymes (DNA ...
متن کاملImaging Lariat RNAs with Reduction-triggered Fluorescent Probes
Numerous biological processes depend on molecules called lariat RNAs (LaRNAs). These lasso-shaped structures form in the cell during RNA splicing. During this process, transcribed RNA strands convert to messenger RNA before undergoing translation into proteins. A way to quickly and efficiently characterize these molecules in living cells is now available, thanks to a method developed by a resea...
متن کاملA Review Of Clinical Trials On LARIAT Device.
The risk of embolic stroke is 5 times higher among patients with atrial fibrillation (AF) compared with those without AF. More than 90% of thrombi form in the left atrial appendage (LAA) in AF. The purpose of this review is to determine the efficacy and safety of the left atrial appendage (LAA) closure via a percutaneous LAA ligation approach, thus preventing a stroke among patients with AF and...
متن کاملLeft atrial thrombus after appendage closure using LARIAT.
The left atrial appendage (LAA) is the source of thromboembolism in the vast majority of patients with atrial fibrillation and stroke. As a consequence, a newer paradigm of targeting the LAA has evolved, including the use of several percutaneous techniques, including the LARIAT snare device (SentreHEART). This minimally invasive strategy involves pericardial suture ligation of the LAA base usin...
