Given an abstract, and a few options, indicate if any of the given options appropriately describe the given abstract. If any of them is a proper keyword, answer 'Yes', otherwise answer 'No'.

Let me give you an example: 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. 
Question Does the following mesh terms have a suitable mesh term for the abstract? 1)Ventricular Fibrillation 2)Transportation of Patients 3)Allied Health Personnel
The answer to this example can be: Yes
Here is why: Ventricular Fibrillation term is directly present in the abstract and it is one of the main topic in it. So can be chosen as the medical subject heading.

OK. solve this:
Abstract: Cells with mutations at the hypoxanthine-guanine phosphoribosyl transferase (HPRT) locus may be detected in vitro by their resistance to the toxic effects of thioguanine. We have assessed HPRT mutants in peripheral blood lymphocytes of patients with connective tissue diseases who have been treated for long periods with cytotoxic drugs. The results from patients treated with cyclophosphamide were abnormal suggesting the presence of drug-induced mutations. The results from patients treated with chlorambucil or azathioprine did not differ from controls--either these drugs have not induced mutations or, more likely, the technique is not sufficiently sensitive to detect them. These possibilities are discussed. Specific mutations induced by cytotoxic drugs in patients with connective tissue diseases have not been previously recorded.
