Given an abstract of a paper, generate a title for this paper such that conveys the key focus of the paper.
One example is below.
Q: Abstract: Some patients converted from ventricular fibrillation to organized rhythms by defibrillation-trained ambulance technicians (EMT-Ds) will refibrillate before hospital arrival. The authors analyzed 271 cases of ventricular fibrillation managed by EMT-Ds working without paramedic back-up. Of 111 patients initially converted to organized rhythms, 19 (17%) refibrillated, 11 (58%) of whom were reconverted to perfusing rhythms, including nine of 11 (82%) who had spontaneous pulses prior to refibrillation. Among patients initially converted to organized rhythms, hospital admission rates were lower for patients who refibrillated than for patients who did not(53% versus 76%, P = NS), although discharge rates were virtually identical (37% and 35%, respectively). Scene-to-hospital transport times were not predictively associated with either the frequency of refibrillation or patient outcome. Defibrillation-trained EMTs can effectively manage refibrillation with additional shocks and are not at a significant disadvantage when paramedic back-up is not available.
A: Refibrillation managed by EMT-Ds
Rationale: The abstract is about refibrillation and it is also mentioned in the abstract that it is managed by EMT-Ds. So it is an apt title.
Q: Abstract: The binding by serum albumin of many drugs and endogenous metabolites is impaired in humans and animals with renal failure. Unknown solute(s) retained in renal failure have been extracted from uremic fluids. When added to normal plasma they induce a similar binding defect. Similar activity can be extracted from normal urine. We have devised a series of extraction and purification techniques that yielded three binding inhibitory ligands from normal human urine in sufficient quantity and of a high degree of purity. Rigorous methods have been applied to determine chemical identity of the ligands. Purification steps consisted of: adsorption at pH 3.0 to polystyrene-divinylbenzene resin (XAD-2); elution from the resin with methanol followed by drying and solution in dilute formic acid; passage through SP-Sephadex to remove cations, especially yellow-brown pigments; adsorption to the anion exchanger QAE-Sephadex, and separation into three zones of inhibitory activity with a formic acid gradient; purification to homogeneity with C-8 or C-18 silica reversed-phase chromatography. Using this isolation procedure, followed by mass spectroscopy and nuclear magnetic resonance spectroscopy, we have shown that the binding inhibitory activity is due not to one ligand, but to a family of aromatic acids. To date hippurate, beta-(m-hydroxyphenyl)-hydracrylate and p-hydroxyphenylacetate have been identified as binding inhibitors. Other active ligands remain to be identified.
