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.

Triterpene alcohols and acids are multifunctional compounds widely distributed throughout the plant kingdom that exhibit a variety of beneficial health properties, being synthetic analogs of oleanolic acid under clinical evaluation as anti-tumoral therapeutic agents. However, the antineoplastic activity of two natural occurring triterpenoid alcohols extracted from olive oil, erythrodiol (an intermediate from oleanolic acid), and its isomer, uvaol, has barely been reported, particularly on brain cancer cells. Astrocytomas are among the most common and aggressive type of primary malignant tumors in the neurological system lacking effective treatments, and in this study, we addressed the effect of these two triterpenic diols on the human 1321N1 astrocytoma cell line.', 'Erythrodiol and uvaol effectively affected cell proliferation, as well as cell cycle phases and induced 1321N1 cell death. Both triterpenes successfully modulated the apoptotic response, promoting nuclear condensation and fragmentation. They caused retraction and rounding of cultured cells, which lost adherence from their supports, while F-actin and vimentin filaments disappeared as an organized cytoplasmic network. At molecular level, changes in the expression of surface proteins associated with adhesion or death processes were also observed. Moreover, triterpene exposure resulted in the production of reactive oxygen species (ROS) with loss of mitochondrial transmembrane potential, and correlated with the activation of c-Jun N-terminal kinases (JNK). The presence of catalase reversed the triterpenic diols-induced mitochondrial depolarization, JNK activation, and apoptotic death, indicating the critical role of ROS in the action of these compounds.

An association between cow's milk hypersensitivity (CMH) and gastro-oesophageal reflux disease (GERD) in childhood has been reported in the past decade.", "To assess whether biopsies from the upper gastrointestinal tract of children with cow's milk sensitive GERD have a specific allergic inflammatory pattern, and to compare two different techniques for measuring inflammatory cells in gastrointestinal biopsies.", "GERD was diagnosed by means of endoscopy and oesophageal pH monitoring. Hypersensitivity to cow's milk was determined by an elimination diet and cow's milk challenge. Allergic inflammatory cells in upper gastrointestinal biopsies were identified by immunohistochemistry and their numbers were assessed by two different methods-counting the number of cells/high power field and using the computerised Cast-Grid system.", "Cow's milk sensitive GERD was identified in 10 of 17 children with severe GERD (median age, 7.8 years). Biopsies from children with endoscopic oesophagitis had significantly increased numbers of mast cells and T cells. No differences in the number of eosinophils, mast cells, or T cells were found between children with CMH and those with primary GERD. Several differences were found between the two different histological quantification methods.

Limited data exist on the risk of developing cardiac sarcoidosis (CS) and/or adverse events in sarcoidosis patients. Using LV global longitudinal strain (GLS), an emerging sensitive parameter of LV function, we evaluated the prevalence of subclinical cardiac dysfunction in sarcoidosis and investigated whether LVGLS predicts adverse outcomes in this population.', 'A total of 130 patients with proven sarcoidosis undergoing echocardiography at our referral centre were identified. Following exclusion of those with evidence of CS (n\u2009=\u200914) or other pre-existing structural heart disease (n\u2009=\u200916), 100 patients (55\u2009±\u200913\u2009years, 48% male, 90% pulmonary involvement) and 100 age- and gender-matched controls were included. LVGLS was measured by speckle-tracking analysis. The primary endpoint was a composite of all-cause mortality, heart failure hospitalization, device implantation, new arrhythmias, or future development of CS on advanced cardiac imaging modalities. LVGLS was significantly impaired in sarcoidosis patients compared with controls (-17.3\u2009±\u20092.5 vs. -20.0\u2009±\u20091.6%, P\u2009<\u20090.001). Overall, 27 patients (27%) reached the endpoint during a median follow-up of 35 months. On Cox proportional hazards model analysis, abnormal 24-h Holter, larger LV end-diastolic diameters, and more impaired LVGLS were significantly associated with the endpoint; however, only LVGLS remained independently associated on multivariate analysis [hazard ratio (HR) 1.4, 95% confidence interval (CI) 1.1-1.7, P\u2009=\u20090.006]. Patients with LVGLS less than -17.3% were significantly more likely to be free of the primary endpoint (log-rank P\u2009=\u20090.01).
