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: In the Drosophila embryo the establishment and specification of metameric units depends upon the selective activation of the segmentation and the homoeotic selector genes. The former are necessary for establishing the appropriate number of metameric or parasegmental units, whereas the latter control the pathways of differentiation followed by particular parasegments. Classical embryological manipulations have show n that these processes must be closely coordinated during normal development. However, previous studies of pair-rule genes have led to the suggestion that the specification of segmental identity proceeds independently of the establishment of metameres as physical units. These apparently conflicting perspectives can be reconciled by envisaging a common maternally derived positional information system which is independently interpreted by the components of both processes. In the case of the partitioning process, the gap and pair-rule genes would be instrumental in translating this information, whereas the activation of the homeotic genes would be mediated via other intermediaries (see ref. 9 for review). It is difficult to see, however, how such a system could ensure the precise regulation of the tw o types of genes implicit in the final differentiated pattern. This difficulty has led to the suggestion that the segmentation mechanism must define the precise boundaries of selector gene expression. Here we confirm this suggestion and propose that the gene fushi tarazu plays a key role in this process, integrating the processes of metameric partitioning and regional specification in the Drosophila embryo.
A:
The correct activation of Antennapedia and bithorax complex genes requires the fushi tarazu gene.
