Input: Consider Input: Context: Intestinal fibrosis is mainly associated with Crohn's disease and is defined as a progressive and excessive deposition of extracellular matrix components. No specific antifibrotic therapies are available. In this study, we evaluate the antifibrotic effect of a novel 5-ASA analog able to activate the peroxisome proliferator-activated receptor γ, named GED-0507-34 Levo.", 'Colonic fibrosis was induced in 110 C57BL/6 mice by 3 cycles of 2.5% (wt/vol) dextran sulfate sodium administration for 6 weeks. The preventive effects of oral daily GED (30 mg · kg(-1) · d(-1)) administration were evaluated using a macroscopic and histological score and also through biological endpoints. Expression of main markers of myofibroblasts activation was determined in transforming growth factor (TGF-β)-stimulated intestinal fibroblasts and epithelial cells.', 'GED improved macroscopic and microscopic intestinal lesions in dextran sulfate sodium-treated animals and reduced the profibrotic gene expression of Acta2, COL1a1, and Fn1 by 1.48-folds (P < 0.05), 1.93-folds (P < 0.005), and 1.03-fold (P < 0.05), respectively. It reduced protein levels of main markers of fibrosis (α-SMA and Collagen I-II) and the main TGF-β/Smad pathway components. GED also decreased the interleukin-13 and connective tissue growth factor expression by 1.89-folds (P < 0.05) and 2.2-folds (P < 0.005), respectively. GED inhibited TGF-β-induced activation of both fibroblast and intestinal epithelial cell lines, by regulating mRNA expression of α-SMA and fibronectin, and restoring the TGF-β-induced loss of intestinal epithelial cell markers. GED treatment also reduced the TGF-β and ACTA1 expression in primary human intestinal fibroblasts from ulcerative colitis patients.
Answer: GED ameliorates intestinal fibrosis in dextran sulfate sodium-induced chronic colitis in mice and regulates major profibrotic cellular and molecular mechanisms.

Output: Does novel PPARγ Modulator GED-0507-34 Levo ameliorate Inflammation-driven Intestinal Fibrosis?


Input: Consider Input: Context: Is weight-training exercise intervention harmful to women with or at risk of breast cancer-related lymphoedema?', 'Systematic review with meta-analysis of randomised trials.', 'Women with or at risk of breast cancer-related lymphoedema.', 'Progressive weight-training exercise.', 'The primary outcomes were severity (volume difference) and incidence of arm lymphoedema. Secondary outcomes included muscle strength of the upper and lower limbs, quality of life and body mass index.', 'Eleven studies from eight trials involving 1091 women were included. Weight-training exercise of low to moderate intensity with relatively slow progression significantly improved the upper limb strength (SMD 0.93, 95% CI 0.73 to 1.12) and lower limb strength (SMD 0.75, 95% CI 0.47 to 1.04) without increasing the arm volume (SMD -0.09, 95% CI -0.23 to 0.05) or incidence of breast cancer-related lymphoedema (RR 0.77, 95% CI 0.52 to 1.15). No significant effects were noted for body mass index (SMD -0.10, 95% -0.31 to 0.11). Some aspects of quality of life may improve with weight training. PARTICIPANTS in all trials used pressure garments and received supervision; no trials used high-intensity weight training.
Answer: Weight training appears to be safe and beneficial in improving limb strength and physical components of quality of life in women with or at risk of lymphoedema. Pressure garments, supervision and limiting the intensity of the weight training may each be important, but this could not be confirmed with this review.

Output: Is weight training harmful for women with breast cancer-related lymphoedema : a systematic review?


Input: Consider Input: Context: To investigate the relationship between follicular blood flow and the follicular fluid vascular endothelial growth factor (VEGF) and nitric oxide (NO) concentrations and to determine which factor might be a better predictor of the outcome of IVF-ET.', 'Prospective study.', 'Academic research laboratory.', 'Forty-seven cycles of IVF (tubal factor, 25 cycles; male factor, 22 cycles) at the infertility clinic of Pusan National University Hospital from February 2002 to June 2002.', 'Follicular blood flow was estimated on the day of hCG administration. Each follicular fluid sample was collected at oocyte retrieval, and follicular fluid VEGF and NO concentrations were assessed.', 'Follicular blood flow and follicular fluid VEGF and NO concentrations according to the age of patients, the cause of infertility, and pregnancy rate.', 'Of 47 cycles, 18 (38.3%) cycles resulted in a pregnancy. Follicular blood flow was significantly higher in the pregnant group compared with the nonpregnant group, but there was no statistically significant difference in age and infertility cause. Follicular fluid concentrations of VEGF and NO did not show statistically significant differences in age, infertility cause, or pregnancy outcome. As the follicle size increases, the follicular blood flow and follicular fluid VEGF concentrations increased significantly but the follicular fluid NO concentrations decreased. There was no correlation between VEGF and NO concentrations in the follicular fluid by linear regression analysis.
Answer: Our study showed that follicular blood flow was positively associated with the outcome of pregnancy. This is the first study to investigate the direct association of the follicular blood flow with pregnancy outcome after IVF-ET. These results suggest that follicular blood flow might be a more effective prognostic marker of the pregnancy outcome of IVF than follicular fluid VEGF or NO concentrations.


Output: Is follicular blood flow a better predictor of the outcome of in vitro fertilization-embryo transfer than follicular fluid vascular endothelial growth factor and nitric oxide concentrations?
