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.

[EX Q]: To determine the effects of maternal undernutrition (MUN) on the reproductive axis of aging offspring.', 'Animal (rat) study.', 'Research laboratory.', 'Female Sprague-Dawley rats.', 'Food restriction during the second half of pregnancy in rats.', 'Circulating gonadotropins, antimullerian hormone (AMH), ovarian morphology, estrous cyclicity, and gene expression studies in the hypothalamus and ovary in 1-day-old (P1) and aging adult offspring.', 'Offspring of MUN dams had low birth weight (LBW) and by adult age developed obesity. In addition, 80% of adult LBW offspring had disruption of estrous cycle by 8 months of age, with the majority of animals in persistent estrous. Ovarian morphology was consistent with acyclicity, with ovaries exhibiting large cystic structures and reduced corpora lutea. There was an elevation in circulating T, increased ovarian expression of enzymes involved in androgen synthesis, an increase in plasma LH/FSH levels, a reduction in E2 levels, and no changes in AMH in adult LBW offspring compared with in control offspring. Hypothalamic expression of leptin receptor (ObRb), estrogen receptor- (ER-), and GnRH protein was altered in an age-dependent manner with increased ObRb and ER- expression in P1 LBW hypothalami and a reversal of this expression pattern in adult LBW hypothalami.

[EX Q]: Although allergic sensitization can be generated against various allergens, it is unknown how such a diversity of antigens is able to promote TH2-mediated inflammation leading to atopy. Our previous studies demonstrated that allergen-specific IgG immune complexes (ICs) and house dust mite (HDM) extract both induced dendritic cells (DCs) to drive TH2-mediated inflammation, but the mechanism by which these diverse stimuli produce similar responses is unknown.', 'We sought to identify the DC signaling pathways used by TH2 stimuli to promote TH2-mediated inflammation.', 'C57BL/6, FcRIII(-/-), FcR(-/-), and ST2(-/-) mice were sensitized and challenged with HDM, and inflammation was assessed based on results of flow cytometry and histology and cytokine production. Bone marrow-derived DCs from these strains were used in signaling and adoptive transfer experiments.', 'Our findings indicate that 2 distinct TH2 stimuli, ICs and HDM, use the FcR-associated receptors FcRIII and Dectin-2, respectively, to promote TH2-mediated lung inflammation. In this study we demonstrate that both ICs and HDM induce expression of IL-33, a critical mediator in asthma pathogenesis and the differentiation of TH2 cells, in DCs. Upregulation of IL-33 in DCs is dependent on FcR, Toll-like receptor 4, and phosphoinositide 3-kinase. Exogenous IL-33 is sufficient to restore the development of TH2 responses in FcR-deficient mice. Finally, adoptive transfer of allergen-pulsed FcR(+/-) bone-marrow derived DCs restores the development of TH2-type inflammation in FcR-deficient mice, demonstrating the necessity of this signaling pathway in DCs for allergen-induced inflammation.

[EX Q]: The nucleus accumbens shell is a key brain area mediating the reinforcing effects of ethanol (EtOH). Previously, it has been shown that the density of -opioid receptors in the nucleus accumbens shell is higher in alcohol-preferring Alko Alcohol (AA) rats than in alcohol-avoiding Alko Non-Alcohol rats. In addition, EtOH releases opioid peptides in the nucleus accumbens and opioid receptor antagonists are able to modify EtOH intake, all suggesting an opioidergic mechanism in the control of EtOH consumption. As the exact mechanisms of opioidergic involvement remains to be elucidated, the aim of this study was to clarify the role of accumbal - and -opioid receptors in controlling EtOH intake in alcohol-preferring AA rats.', 'Microinfusions of the -opioid receptor antagonist CTOP (0.3 and 1g/site), -opioid receptor agonist DAMGO (0.03 and 0.1g/site), nonselective opioid receptor agonist morphine (30g/site), and -opioid receptor agonist U50488H (0.3 and 1g/site) were administered via bilateral guide cannulas into the nucleus accumbens shell of AA rats that voluntarily consumed 10% EtOH solution in an intermittent, time-restricted (90-minute) 2-bottle choice access paradigm.', 'CTOP (1g/site) significantly increased EtOH intake. Conversely, DAMGO resulted in a decreasing trend in EtOH intake. Neither morphine nor U50488H had any effect on EtOH intake in the used paradigm.
