Given a passage classify if the passage has a definite objective/aim/goal or not. Output '1' if the passage has a defininte objective/aim/goal and output '0' if the passage does not have a definite objective/aim/goal.

Uterine leiomyomas are the most frequent benign tumors during reproductive age. Whether intramural leiomyomas cause infertility and should be removed is controversial because no study has addressed the underlying mechanism of infertility.', 'The objective of the study was to test the effect of intramural leiomyomas on endometrial function by comparing gene during the window of implantation and implantation in an oocyte donation program, in which the quality of the embryos replaced is similar and the endocrine environment of the endometrium is standardized by exogenous steroids.', 'Human endometria of women with single intramural leiomyomas (group A, <5 cm and group B, > or =5 cm) and controls (group C) were collected on day LH+7 and processed for histology and gene expression analysis, using different methods and validated by quantitative RT-PCR. To compare in vitro fertilization outcome, a total of 1035 cases from our oocyte donation database were included, comprising patients with one fibroid less than 5 cm (A1, n = 532); two leiomyomas less than 5 cm (A2, n = 128); three or more leiomyomas less than 5 cm (A3, n = 125); one fibroid 5 cm or greater (B, n = 22); and two control groups: C1 (n = 93), women with previous myomectomy; and C2 (n = 135), women without uterine pathology treated on the same dates as C1.', "There was a strong positive and negative correlation in the expression profile of 69 genes according to the leiomyomas's size, but only three of the 25 genes related to the window of implantation were dysregulated. Term pregnancy rates after oocyte donation were 36.9, 34.1, 39.0, 36.4, 39.2, and 42.6% (P = 0.769) among the established groups. Similarly, no correlation between implantation and miscarriage with leiomyoma number and size was found.

Rush immunotherapy (RIT) presents an attractive alternative to standard immunotherapy. However, RIT carries a much greater risk of acute allergic reactions, including anaphylaxis.', 'We hypothesized that omalizumab, a humanized monoclonal anti-IgE antibody, would be effective in enhancing both safety and efficacy of RIT.', 'Adult patients with ragweed allergic rhinitis were enrolled in a 3-center, 4-arm, double-blind, parallel-group, placebo-controlled trial. Patients received either 9 weeks of omalizumab (0.016 mg/kg/IgE [IU/mL]/mo) or placebo, followed by 1-day rush (maximal dose 1.2-4.0 mug Amb a 1) or placebo immunotherapy, then 12 weeks of omalizumab or placebo plus immunotherapy.', 'Of the 159 patients enrolled, 123 completed all treatments. Ragweed-specific IgG levels increased >11-fold in immunotherapy patients, and free IgE levels declined >10-fold in omalizumab patients. Patients receiving omalizumab plus immunotherapy had fewer adverse events than those receiving immunotherapy alone. Post hoc analysis of groups receiving immunotherapy demonstrated that addition of omalizumab resulted in a 5-fold decrease in risk of anaphylaxis caused by RIT (odds ratio, 0.17; P = .026). On an intent-to-treat basis, patients receiving both omalizumab and immunotherapy showed a significant improvement in severity scores during the ragweed season compared with those receiving immunotherapy alone (0.69 vs 0.86; P = .044).

Ex Input:
Macrophages promote tumor growth by stimulating tumor-associated angiogenesis, cancer-cell invasion, migration, intravasation, and suppression of antitumor immune responses.', 'Ten transgenic nude mice, ubiquitously expressing green fluorescent protein (GFP), were injected subcutaneously with the human pancreatic cancer cell line, BXPC3, stably expressing red fluorescent protein (RFP). GFP-expressing macrophages from the GFP mice with the subcutaneous BxPC3-RFP tumor were harvested and defined as "tumor-educated macrophages". Macrophages were also harvested from transgenic GFP mice (n=10) without tumors and identified as "naive macrophages." The tumor-educated and naive macrophages were then implanted into BxPC-3-RFP tumor-bearing non-transgenic nude mice and compared for their ability to enhance tumor progression.', 'In the control group, without macrophage injection, the average primary tumor weighed 668 mg and only three mice (30%) developed peritoneal metastases, which averaged 72 mg. The naive-macrophage group had an average tumor weight of 823 mg (p=0.51) and 50% developed peritoneal metastases, whose weight averaged 975 mg (p=0.029). The group treated with tumor-educated macrophages had an average primary tumor weight of 2095 mg (p=0.001) and 75% of mice developed peritoneal metastases, whose weight averaged 2135 mg (p=0.008).
