In this task, you are given a passage which has a question and the context. You have to generate an answer to the question based on the information present in the context.

Context: Data on combined coronary artery bypass grafting (CABG) and restrictive annuloplasty in patients with ischemic cardiomyopathy are scarce, and the effect on reverse left ventricular (LV) remodeling is unknown.', '51 patients with ischemic LV dysfunction (LV ejection fraction 31+/-8%) and severe mitral regurgitation (grade 3 to 4+) underwent CABG and restrictive annuloplasty with stringent downsizing of the mitral annulus (by 2 sizes, Physio-ring, mean size 28+/-2). Serial transthoracic echocardiographic studies were performed (before surgery and within 3 months and 1.5 years after surgery) to assess mitral regurgitation, transmitral gradient, leaflet coaptation, and left atrial and LV reverse remodeling. Clinical follow-up (New York Heart Association [NYHA] class, survival, events) was assessed at 2-year follow-up. Early operative mortality was 5.6%; at 2-year follow-up, all patients were free of endocarditis and thromboembolism, and 1 needed re-operation for recurrent mitral regurgitation; 2-year survival was 84%. NYHA class improved from 3.4+/-0.8 to 1.3+/-0.4 (P<0.01), with all patients in class I/II. Intraoperative transesophageal echo showed minimal (grade 1+) mitral regurgitation in 8 patients and none in 43, without stenosis. Leaflet coaptation was 0.8+/-0.2 cm. These values remained unchanged; all patients had no or minimal (grade 1+) mitral regurgitation at 2-year follow-up. LV end-systolic and end-diastolic dimensions decreased from 51+/-10 to 43+/-12 mm (P<0.001) and from 64+/-8 to 58+/-11 mm (P<0.001). Left atrial dimension decreased from 53+/-8 to 47+/-7 mm (P<0.001).\Question: Does restrictive annuloplasty and coronary revascularization in ischemic mitral regurgitation result in reverse left ventricular remodeling?
Excellent results of combined restrictive annuloplasty and CABG were obtained. Residual mitral regurgitation was absent/minimal at 2-year follow-up, associated with a significant reduction in left atrial dimension and LV reverse remodeling.

Context: To determine the role of recipient lymphopenia state in the expansion and function of leukemia specific cytotoxic T lymphocytes (CTLs).', 'C57BL/6 mice were induced to lymphopenia with 6 Gy total body irradiation. Spleen T cells or leukemia specific T cells from EGFP+ transgenic C57BL/6-EGFP mice were adoptively transferred by intravenous injection. The mice were challenged subcutaneously with 1 x 10(6) FBL3 leukemic cells at day 2 after irradiation. The peripheral WBC count, percentage of EGFP+ cells, subsets of T cells and tumor sizes were monitored.', 'Both of the spleen T cell and leukemia specific CTL proliferated efficiently with the percentage of EGFP+ cells of 28. 81% and 42.24%, respectively, after infused into lymphopenic recipients. However, spleen T cells had no anti-leukemia effect regardless of its expansion. In contrast, leukemia specific CTLs showed a more rapid and extensive expansion under the condition of lymphopenia and a enhanced anti-leukemia immunity.\Question: Does [ Recipient lymphopenia state enhance the expansion and anti-leukemia effect of leukemia specific cytotoxic T lymphocytes ]?
Transfusion of leukemia specific CTLs under lymphopenia state could be a feasible strategy to expand leukemia specific CTLs and generate favorable anti-leukemia effect in vivo.

Context: Previous research demonstrating that specific performance outcome goals can be achieved in different ways is functionally significant for springboard divers whose performance environment can vary extensively. This body of work raises questions about the traditional approach of balking (terminating the takeoff) by elite divers aiming to perform only identical, invariant movement patterns during practice.', 'A 12-week training program (2 times per day; 6.5 hr per day) was implemented with 4 elite female springboard divers to encourage them to adapt movement patterns under variable takeoff conditions and complete intended dives, rather than balk.', "Intraindividual analyses revealed small increases in variability in the board-work component of each diver's pretraining and posttraining program reverse-dive takeoffs. No topological differences were observed between movement patterns of dives completed pretraining and posttraining. Differences were noted in the amount of movement variability under different training conditions (evidenced by higher normalized root mean square error indexes posttraining). An increase in the number of completed dives (from 78.91%-86.84% to 95.59%-99.29%) and a decrease in the frequency of balked takeoffs (from 13.16%-19.41% to 0.63%-4.41%) showed that the elite athletes were able to adapt their behaviors during the training program. These findings coincided with greater consistency in the divers' performance during practice as scored by qualified judges.\Question: Does increasing functional variability in the preparatory phase of the takeoff improve elite springboard diving performance?
Results suggested that on completion of training, athletes were capable of successfully adapting their movement patterns under more varied takeoff conditions to achieve greater consistency and stability of performance outcomes.
