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.

[Q]: Epidermal growth factor (EGF) has been shown to induce intestinal proliferation and maturation; however, little information is available regarding substrates of the intestinal EGF receptor tyrosine kinase. The purpose of this study was to determine if src homologous collagen-like protein (Shc) was an in vivo substrate of the intestinal EGF receptor.', 'Ten-day-old rats were treated with EGF or were breast-fed. In some experiments, IEC-6 cells were treated with EGF. Intestinal tissue and cell fractions were studied by immunodetection to compare the tyrosine phosphorylation state and the subcellular localization of intestinal proteins.', 'The total tyrosine phosphorylation state of intestinal proteins was increased threefold by EGF. Tyrosine phosphorylation of the EGF receptor and Shc were rapidly increased by EGF. The association of Grb2 with Shc increased fourfold and fivefold. Plasma membrane translocation of Shc and associated phosphotyrosyl proteins was increased within 30 seconds of EGF treatment.

[Q]: 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.

[Q]: This study reports on an extremely rare case of tuberculous psoas abscess and describes the mode of diagnosis and treatment.', 'This patient is presented to emphasize that cases of solitary psoas abscess resulting from tuberculosis exist today.', "No recent cases of latent solitary tuberculous psoas abscess have been reported, to the authors' knowledge.", 'A tuberculous psoas abscess associated with fistula to the greater trochanter may remain dormant for years after tuberculous spondylitis has healed, as a distinct entity without concomitant active bone infection. In our 58-year-old female patient, the diagnosis of a psoas abscess was greatly aided by the "three pass" technetium bone scan and computed tomography, but the anamnesis also was important.', 'Anti-tuberculosis medication (streptomycin, aminosalicylic, and isoniazid) combined with open drainage, curettage of the psoas, and simultaneous revision of the fistula eradicated the disease, making the course of the disease uneventful until the 5-year follow-up evaluation.
