Does early administration of tolvaptan preserve renal function in elderly patients with acute decompensated heart failure?
Early administration of TLV, compared to increased FRM dosage, reduces the incidence of WRF in real-world elderly ADHF patients. In addition, it reduces the occurrence of 'worse' WRF-persistent and late-onset WRF-which are associated with increased rates of cardiac death or readmission for worsening heart failure in the 90 days after discharge.
We have demonstrated that a Rho GTPase signaling pathway regulates katanin-mediated MT severing in plant cells and uncovered an explicit regulatory mechanism underpinning the alignment and ordering of cortical MTs in plants. Our findings provide new insights into regulatory mechanisms underlying growth stimuli such as auxin promote the organization of cortical MTs into parallel arrays in plants.
