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]: Weight-loss is a near societal obsession and many diet programs use significant calorie restriction including fasting/short term starvation to generate rapid effects. Fasting is also a well-recognized cause of immunosuppression especially within the innate immune system. In this study, we sought to determine if the IL-1 arm of the neuroimmune system was down-regulated by a 24\u2009h fast and how fasting might generate this effect.', 'Mice were allowed ad libitum access to food or had food withheld for 24\u2009h. Expression of the endogenous IL-1 antagonists, IL-1 receptor type 2 (IL-1R2), and IL-1 receptor antagonist (IL-1RA) was determined as were sickness behaviors before and after IL-1β administration.', 'Fasting markedly increased gene expression of IL-1R2 (83-fold in adipose tissue, 9.5-fold in liver) and IL-1RA (68-fold in liver). Fasted mice were protected from IL-1β-induced weight-loss, hypoglycemia, loss of locomotor, and social anxiety. These protections were coupled to a large positive interaction of fasting and IL-1β on IL-1R2 gene expression in adipose tissue and liver (2.6- and 1.6-fold, respectively). Fasting not only increased IL-1RA and IL-1R2 protein 2.5- and 3.2-fold, respectively, in liver but also increased IL-1R2 1.8-fold in adipose tissue. Fasting, in turn, triggered a 2.4-fold increase in plasma free-fatty acids (FFAs) and a 2.1-fold increase in plasma corticosterone. Inhibition, of glucocorticoid action with mifepristone did not impact fasting-dependent IL-1R2 or IL-1RA gene expression. Administration of the FFA, palmitate, to mice increased liver IL-1R2 and IL-1RA gene expression by 14- and 11-fold, respectively.

[EX Q]: Radiofrequency applications to the posteroseptal region can ablate the atrioventricular accessory pathway residing in this area. In conjunction with the adjacent anatomic structures, however, ablative lesions which do not effectively ablate the accessory pathway could markedly alter retrograde atrial activation sequence and confound interpretation of further mapping of an accessory pathway.', 'Electrophysiologic studies, endocardial activation mapping and radiofrequency catheter ablation were undertaken in three patients with recurrent supraventricular tachycardia. Patients were initially thought to have a single posteroseptal accessory pathway; earliest ventrioatrial activation during tachycardias and during ventricular pacing was at the coronary sinus ostium, but initial radiofrequency applications were unsuccessful to ablate the pathway. After initial radiofrequency applications to the posteroseptal region, the earliest retrograde atrial activation changed to the right atrial free wall in two patients. Additional radiofrequency application to the posteroseptal area was able to ablate the single posteroseptal accessory pathway in one patient. Radiofrequency application to the right atrial free wall was required to stop tachycardia initiation in other patient. The third patient was suspected of having a slow-slow atrioventricular nodal reentry tachycardia. Radiofrequency application to the posteroseptal area changed the earliest retrograde atrial activation to the distal coronary sinus recording site, mimicking an accessory pathway at the left atrial free wall. Radiofrequency application to the anteroseptum was able to ablate the concealed accessory pathway.

[EX Q]: Histiocytoid Sweet syndrome (HSS) is a rare variant of Sweet syndrome (SS). The nature of histiocytoid cells is still uncertain.', 'We sought to offer a comprehensive overview on clinical features of HSS and further information on immunohistochemical phenotype of the infiltrate.', 'The clinical, histologic, and immunohistochemical features of 12 of our patients with HSS and all cases retrieved through a PubMed search were analyzed.', 'Lesions consisted of erythematous-violaceous papules and plaques, randomly distributed mostly on the trunk and the limbs. Three patients had myelodysplastic syndrome and 1 had a monoclonal gammopathy. The infiltrate was mainly composed of CD68(+)CD163(+)myeloperoxidase(+)myeloid cell nuclear differentiation antigen(+)CD117(-)CD15(-)CD34(-), a phenotype suggestive of M2-like macrophages. A few mature neutrophils and lymphocytes were also present. Review of all HSS cases showed no sex predominance and no extracutaneous infiltrates; inconstant presence of fever and blood neutrophilia; association with hematologic or solid neoplasms (26%), autoimmune conditions (12%), and infectious diseases (10%); and good response to steroid treatment, with rare relapses or recurrences.
