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.

Input: Consider Input: Context: Alternative splicing is important for increasing the complexity of the human proteome from a limited genome. Previous studies have shown that for some autoantigens, there is differential immunogenicity among alternatively spliced isoforms.', 'Herein, we tested the hypothesis that alternative splicing is a common feature for transcripts of autologous proteins that are autoantigens. The corollary hypothesis tested was that nonautoantigen transcripts have a lower frequency of alternative splicing.', 'The extent of alternative splicing within 45 randomly selected self-proteins associated with autoimmune diseases was compared with 9554 randomly selected proteins in the human genome by using bioinformatics analyses. Isoform-specific regions that resulted from alternative splicing were studied for their potential to be epitopes for antibodies or T-cell receptors.', 'Alternative splicing occurred in 100% of the autoantigen transcripts. This was significantly higher than the approximately 42% rate of alternative splicing observed in the 9554 randomly selected human gene transcripts ( P < .001). Within the isoform-specific regions of the autoantigens, 92% and 88% encoded MHC class I and class II-restricted T-cell antigen epitopes, respectively, and 70% encoded antibody binding domains. Furthermore, 80% of the autoantigen transcripts underwent noncanonical alternative splicing, which is also significantly higher than the less than 1% rate in randomly selected gene transcripts ( P < .001).\Question: Does increased noncanonical splicing of autoantigen transcripts provide the structural basis for expression of untolerized epitopes?

Output: These studies suggest that noncanonical alternative splicing may be an important mechanism for the generation of untolerized epitopes that may lead to autoimmunity. Furthermore, the product of a transcript that does not undergo alternative splicing is unlikely to be a target antigen in autoimmunity.


Input: Consider Input: Context: To determine whether macrophages in human reproductive tissues contain luteinizing hormone (LH)/human chorionic gonadotropin (hCG) receptor mRNA and receptor protein that can bind 125I-hCG.', 'Macrophages isolated from term pregnancy human decidua were used for LH/hCG receptor detection by in situ hybridization for receptor mRNA and immunocytochemistry for a macrophage marker, CD68, performed alone and in combination, reverse transcription-nested polymerase chain reaction, Western and ligand blotting. The LH/hCG receptor presence in macrophages in late luteal phase human endometria and corpora lutea was determined by sequential performance of in situ hybridization and immunocytochemistry.', 'The macrophages present in term pregnancy human decidua and late luteal phase human endometria and corpora lutea contain LH/hCG receptors.\Question: Do macrophages in human reproductive tissues contain luteinizing hormone/chorionic gonadotropin receptors?

Output: This is the first demonstration of macrophages present in human reproductive tissues containing LH/hCG receptors. The receptor presence suggests that LH and hCG may regulate macrophage functions in gonadal as well as in non-gonadal target tissues.


Input: Consider Input: Context: To compare endocrine profiles and IVF outcomes after using GnRH agonists (GnRHa) to trigger final oocyte maturation in women with polycystic ovary syndrome (PCOS) with other hyper-responders.', 'Retrospective cohort study.', 'Academic center.', 'Forty women with PCOS and 74 hyper-responders without PCOS.', 'GnRHa trigger.', 'Number of oocytes.', 'Serum E2, LH, and P levels on the day of GnRHa trigger and the day after trigger did not differ significantly between groups. There were no significant differences in total number of oocytes or percent mature oocytes obtained between groups after controlling for age, antral follicle count, and total days of stimulation. The overall rate of no retrieval of oocytes after trigger was low (2.6%). Fertilization, implantation, clinical pregnancy, and live-birth rates were similar in the two groups. No patients developed ovarian hyperstimulation syndrome (OHSS).\Question: Is use of gonadotropin-releasing hormone agonist trigger during in vitro fertilization associated with similar endocrine profiles and oocyte measures in women with and without polycystic ovary syndrome?


Output: The similar post-GnRHa trigger hormone profiles and mature oocyte yield support the routine use of GnRHa trigger to prevent OHSS in women with PCOS.
