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.

Fibroblasts (FIBs) within the retro-orbital space of patients with Graves' disease (GOFs) express thyrotropin receptors (TSHRs) and are thought to be an orbital target of TSHR-stimulating autoantibodies in Graves' ophthalmopathy (GO). Recently, we developed a low molecular weight, drug-like TSHR antagonist (NCGC00229600) that inhibited TSHR activation in a model cell system overexpressing TSHRs and in normal human thyrocytes expressing endogenous TSHRs. Herein, we test the hypothesis that NCGC00229600 will inhibit activation of TSHRs endogenously expressed in GOFs.", 'Three strains of GOFs, previously obtained from patients with GO, were studied as undifferentiated FIBs and after differentiation into adipocytes (ADIPs), and another seven strains were studied only as FIBs. ADIP differentiation was monitored by morphology and measurement of adiponectin mRNA. FIBs and ADIPs were treated with the TSH- or TSHR-stimulating antibody M22 in the absence or presence of NCGC00229600 and TSHR activation was monitored by cAMP production.', 'FIBs contained few if any lipid vesicles and undetectable levels of adiponectin mRNA, whereas ADIPs exhibited abundant lipid vesicles and levels of adiponectin mRNA more than 250,000 times greater than FIBs; TSHR mRNA levels were 10-fold higher in ADIPs than FIBs. FIBs exhibited higher absolute levels of basal and forskolin-stimulated cAMP production than ADIPs. Consistent with previous findings, TSH stimulated cAMP production in the majority of ADIP strains and less consistently in FIBs. Most importantly, NCGC00229600 reduced both TSH- and M22-stimulated cAMP production in GOFs.

Endothelin receptor antagonists improve pulmonary arterial hypertension (PAH). Mutations in the bone morphogenetic protein (BMP) type 2 receptor (BMPR2) predispose to PAH. Here, we sought to determine whether there might exist interactions between these 2 signaling pathways and their effect on the acquisition of the altered phenotype of pulmonary artery smooth muscle cells (PA-SMCs) observed in PAH.', 'Expression of BMPR2, of the BMP agonist BMP4, and of the BMP antagonists gremlin1 and gremlin2 was evaluated in lungs and in PA-SMCs from 6 PAH patients and 14 controls treated with endothelin-1. Endothelin-1 pre-treated PA-SMCs were assessed for proliferation, apoptosis, and downstream signaling activation of Smad1/5/8 and p38 mitogen-activated protein kinase (p38(MAPK)) after BMP2 treatment.', 'In PA-SMCs from PAH patients, expression of BMPR2 and BMP4 decreased, whereas expression of gremlin1 and gremlin2 increased compared with controls. Treatment of control PA-SMCs with endothelin-1 induced a dose-dependent increase in gremlin1 and gremlin2, whereas BMPR2 and BMP4 expression decreased, reaching similar levels as those observed in PAH cells. In control PA-SMCs, endothelin-1 pre-treatment reduced inhibitor of DNA binding 1 (Id1) expression and Smad1/5/8 activation induced by BMP2, whereas it enhanced p38(MAPK) activation. Moreover, BMP2 decreased serum-induced proliferation and increased the pro-apoptotic Bax/Bcl-2 ratio. These effects were attenuated by endothelin-1 pre-treatment. Endothelin-1 did not alter BMPR2 signaling in PA-SMCs from PAH patients.

Trauma centers often receive transfers from lower-level trauma centers or nontrauma hospitals. The aim of this study was to analyze the incidence and pattern of secondary overtriage to our Level I trauma center.', 'We performed a 2-year retrospective analysis of all trauma patients transferred to our Level I trauma center and discharged within 24 hours of admission. Reason for referral, referring specialty, mode of transport, and intervention details were collected. Outcomes measures were incidence of secondary overtriage as well as requirement of major or minor procedure. Major procedure was defined as surgical intervention in the operating room. Minor procedures were defined as procedures performed in the emergency department.', 'A total of 1,846 patients were transferred to our Level I trauma center, of whom 440 (24%) were discharged within 24 hours of admission. The mean (SD) age was 35 (21) years, 72% were male, and mean (SD) Injury Severity Score (ISS) 4 (4). The most common reasons for referral were extremity fractures (31%), followed by head injury (23%) and soft tissue injuries (13%).Of the 440 patients discharged within 24 hours, 380 (86%) required only observation (268 of 380) or minor procedure (112 of 380). Minor procedures were entirely consisted of fracture management (n = 47, 42%) and wound care (n = 65, 58%). The mean (SD) interfacility transfer distance was 45 (46) miles. Mean (SD) hospital charges per transfer were $12,549 ($5,863).
