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: Dehydroepiandrosterone (DHEA) was shown to improve the immune function and survival in experimental sepsis. This study examined the effect of DHEA on intestinal leukocyte recruitment during experimental sepsis, considering factors of gender (male, female and ovariectomized female animals) and combined treatment using orthovanadate (OV) in two models of sepsis.', 'Male rats underwent colon ascendens stent peritonitis (CASP) or endotoxemia. DHEA was administered after induction of experimental sepsis. Changes in leukocyte adherence and capillary perfusion (measured as intestinal functional capillary density - FCD) were assessed using intravital microscopy. While DHEA increased baseline leukocyte adherence in control animals, DHEA reduced leukocyte adherence and increased FCD in male animals with CASP. These effects were also observed in DHEA-treated ovariectomized female rats with CASP. Similarly, the administration of DHEA reduced the number of adherent leukocytes to intestinal venules by 30% in the endotoxemia model. The combined treatment of DHEA and OV significantly reduced adherence of leukocytes to intestinal venules and improved FCD.\Question: Does combination of dehydroepiandrosterone and orthovanadate administration reduce intestinal leukocyte recruitment in models of experimental sepsis?

Output: Our results indicate that DHEA is able to reduce intestinal leukocyte recruitment induced by experimental sepsis. Combination of DHEA with OV inhibits leukocyte adherence to intestinal endothelium, similar to what is achieved by the single administration of DHEA but with significantly improved FCD. These findings suggest a potential role for DHEA and OV in clinical sepsis.


Input: Consider Input: Context: The gene(s) encoding for endomorphin precursor(s) is/are still unknown. We have raised the possibility of and did find some evidence for a potential de novo biosynthetic route starting from Tyr-Pro precursor. To pursue further this possibility we measured the generation of immunoreactive endomorphin-2 (E2-IR) in adult rat isolated L4,5 dorsal root ganglia.\Question: Is immunoreactive endomorphin 2 generated extracellularly in rat isolated L4,5 dorsal root ganglia by DPP-IV?

Output: In rat isolated dorsal root ganglia the combination of presumed biosynthetic precursor of endomorphin 2 (E2), Tyr-Pro with the dipeptidyl peptidase IV (DPP-IV) inhibitor Ile-Pro-Ile generated 1.60+/-0.37 pg/mg Wet Tissue Weight_30 min E2-IR in the bathing fluid (n=4) with an 8-fold increase upon depolarization whereas the tissue content was low (0.50+/-0.08 pg/mg_WTW). Substance P, as determined by ELISA in the pilot experiments, was found almost exclusively within the tissues. It is concluded that E2-IR was generated extracellularly by a membrane-bound DPP-IV, which was switched to "synthase" mode by the hydrolase inhibitor Ile-Pro-Ile. DPP-IV was depolarization-sensitive in "synthase" functional mode.


Input: Consider Input: Context: We assessed the expression of natural killer (NK) receptors in recurrent aborters before and after immunotherapy using their husbands' peripheral blood mononuclear cells (PBMCs).", 'Using stored PBMCs from recurrent aborters before and after the immunotherapy, the expression of NK receptors, CD158a, CD158b, CD159 and CD94, were analyzed using monoclonal antibodies for respective receptors. The diversity of killer activatory receptors (KARs) and killer inhibitory receptors (KIRs) was also examined using reverse transcriptase-polymerase chain reaction (RT-PCR)-single strand conformation polymorphism (SSCP) method.', 'In recurrent aborters, no apparent changes in NK receptor expression and the balance between KARs and KIRs were found before and after the immunotherapy.\Question: Does immunotherapy prevent recurrent abortion without influencing natural killer receptor status?


Output: The allo-human leukocyte antigen (HLA)-stimulation caused by the immunotherapy for recurrent aborters did not affect the expression of NK receptors and the ratio of KARs to KIRs regardless of the outcome of subsequent pregnancies, suggesting that recurrent aborters may benefit from the immunotherapy through mechanisms unrelated to alteration in NK receptor status.
