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.

Example Input: Context: We sought to assess whether mechanical unloading has beneficial effects on cardiomyocytes from doxorubicin-induced cardiomyopathy in rats.', 'Mechanical unloading by a left ventricular assist device (LVAD) improves the cardiac function of terminal heart failure in humans. However, previous animal studies have failed to demonstrate beneficial effects of mechanical unloading in the myocardium.', 'The effects of mechanical unloading by heterotopic abdominal heart transplantation were evaluated in the myocardium from doxorubicin-treated rats by analyzing the intracellular free calcium level ([Ca(2+)](i)) and the levels of intracellular Ca(2+)-regulatory proteins.', 'In doxorubicin-treated rats, the duration of cell shortening and [Ca(2+)](i) transients in cardiomyocytes was prolonged (432 +/- 28.2% of control in 50% relaxation time; 184 +/- 10.5% of control in [Ca(2+)](i) 50% decay time). Such prolonged time courses significantly recovered after mechanical unloading (114 +/- 10.4% of control in 50% relaxation time; 114 +/- 5.8% of control in 50% decay time). These effects were accompanied by an increase in sarcoplasmic reticulum Ca(2+) ATPase (SERCA2a) protein levels (0.97 +/- 0.05 in unloaded hearts vs. 0.41+/- 0.09 in non-unloaded hearts). The levels of other intracellular Ca(2+)-regulatory proteins (phospholamban and ryanodine receptor) were not altered after mechanical unloading in doxorubicin-treated hearts. These parameters in unloaded hearts without doxorubicin treatment were similar to normal hearts.\Question: Does mechanical unloading improve intracellular Ca2+ regulation in rats with doxorubicin-induced cardiomyopathy?
Example Output: Mechanical unloading increases functional sarcoplasmic reticulum Ca(2+) ATPase and improves [Ca(2+)](i) handling and contractility in rats with doxorubicin-induced cardiomyopathy. These beneficial effects of mechanical unloading were not observed in normal hearts.

Example Input: Context: Chronic inflammation in periodontal disease is associated with increased plasminogen activation and elevated levels of chemokines. It is unknown whether chemokines can regulate the activation of plasminogen via modulation of plasminogen activators (PA) and the corresponding plasminogen activator inhibitors (PAI) in periodontal tissue.', 'To establish a link between chemokines and activation of plasminogen, human periodontal ligament fibroblasts (PDL) and gingival fibroblasts (GF) were incubated with IL-8, monocyte chemoattractant protein-1, macrophage inflammatory protein-1alpha, and platelet factor-4, either alone or in the presence of the inflammatory mediators TGF-beta and IL-1. The potential of the cell lysates to activate plasminogen was based on kinetic studies with the substrate casein. Casein zymography was performed to determine the molecular sizes of the PA. Total PAI-1 in the cell-conditioned medium was quantified by immunoassay.', 'We report that the chemokines did not affect activation of plasminogen by PDL and GF. Even in the presence of TGF-beta which suppressed, and IL-1 which stimulated plasminogen activation, the chemokines had no direct effect. Inhibition of PA and plasmin, but not of matrix metalloproteinases and cysteine proteinases prevented caseinolysis. The plasminogen activation capacity of the cell lysates was represented by a single band with features of uPA. The immunoassay showed that the release of PAI-1 in PDL and GF remained unaffected by the chemokines, also when stimulated with TGF-beta.\Question: Is plasminogen activation by fibroblasts from periodontal ligament and gingiva directly affected by chemokines in vitro?
Example Output: These results suggest that plasminogen activation by PDL and GF is not directly affected by the chemokines even in the presence of the inflammatory mediators TGF-beta and IL-1.

Example Input: Context: To evaluate manual lymphatic drainage (MLD) and active exercise effects on lymphatic alterations of the upper limb (UL), range of motion (ROM) of shoulder, and scar complications after breast cancer surgery.', 'Clinical trial.', 'Health care center.', 'Women (N=105) undergoing radical breast cancer surgery who were matched for staging, age, and body mass index.', 'Women (n=52) were submitted to MLD and 53 to active exercises for UL for 1 month and followed up.', 'Shoulder ROM, surgical wound inspection and palpation, UL circumference measurements, and lymphoscintigraphy were performed in preoperative and postoperative periods.', 'There was no significant difference between groups with regard to wound healing complications, ROM, and UL circumferences. After surgery, 25 (48.1%) of the MLD group and 19 (35.8%) of the active exercise group showed worsening in radiopharmaceutical uptake velocity, whereas 9 (17.3%) of the MLD group and 11 (20.8%) of the active exercise group showed improved velocity (P=.445). With regard to uptake intensity, 27 (51.9%) of the MLD group and 21 (39.6%) of the active exercise group showed worsening whereas 7 (13.5%) of the MLD group and 7 (13.2%) of the active exercise group showed some improvement (P=.391). The presence of collateral circulation was similar in both groups at both time points evaluated. The active exercise group had a significant increase in postoperative liver absorption (P=.005), and the MLD group had a significant increase in postoperative dermal backflow (P=.024).\Question: Do manual Lymphatic Drainage and Active Exercise Effects on Lymphatic Function Translate Into Morbidities in Women Who Underwent Breast Cancer Surgery?
Example Output:
MLD and active exercise effects are equivalent with regard to morbidity. Minor changes in lymphatic function associated with either MLD or active exercises were not related to patients' symptoms or signs.
