instruction:
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.
question:
Airway hyperresponsiveness (AHR) is associated with persistent air flow limitation and accelerated FEV(1) decline. AHR can influence diagnosis, treatment, and prognosis. We assessed the value of pulmonary function variables, symptoms, and history as selection criteria for methacholine bronchoprovocation testing to detect AHR in symptomatic subjects.', 'Over a 4-year period we conducted a prospective study of consecutive subjects who underwent methacholine bronchoprovocation testing. Baseline pulmonary function testing (PFT) and a questionnaire were obtained prior to methacholine bronchoprovocation testing. PFT and symptom and history variables were assessed as AHR predictors in univariate and multiple logistic regression analyses for the whole group and for 4 different age groups.', 'There were 530 subjects, with ages ranging from 5 to 87 years, and 232 (44%) were positive for methacholine AHR. AHR was more prevalent among subjects < or = 25 years old (59%) and > 65 years old (47%) than among the other age groups. PFT values, symptom, and history variables had different AHR predictive values among the different age groups. Symptom and history variables had no AHR predictive value among subjects < or = 25 or > 65 years old.

question:
Increased apoptosis has recently been reported in the heart of spontaneously hypertensive rats (SHRs).', 'To investigate the molecular basis of apoptosis in the left ventricle of SHRs in terms of the expression of Bcl-2 protein (which protects from apoptosis) and Bax protein (which acts as an apoptotic promoter). In addition, we analysed the involvement of alpha -adrenergic receptors in the left ventricular apoptosis of SHRs.', 'The study was performed in untreated SHRs (n=16) and SHRs that were orally treated with doxazosin (10 mg/kg body weight per day, for 15 days), a selective alpha1-receptor blocker (n=16). A group of Wistar-Kyoto (WKY) rats (n=16) was used as the control.', 'The left ventricles of untreated SHRs showed a significant increase in Bcl-2 protein expression and a reduced presence of Bax protein. The ratio of Bcl-2:Bax in SHRs was higher than in WKY rats, suggesting an anti-apoptotic state. Paradoxically, both the number of apoptotic cardiac cells and the cleavage of an 85-kDa fragment of the poly (ADP-ribose) polymerase (PARP), a marker of caspase-3 activity, were higher in the left ventricle of SHRs than in WKY rats, suggesting an apoptotic situation. Bax promotes cell apoptosis when it is bound to Bcl-2. We then determined the abundance of Bax-Bcl-2 complexes in the left ventricle of the two groups of animals. Bax-Bcl-2 complexes were more abundant in SHRs than WKY rats. In a second set of experiments, we analysed the role of alpha1-adrenergic blockade by doxazosin in the above-described mechanisms. Doxazosin treatment reduced the formation of Bax-Bcl-2 complexes in the left ventricle of SHRs, and this was accompanied by a decrease in the levels of 85kDa PARP and a reduction in apoptotic left ventricular cells.

question:
Inflammation plays a central role in many neurodegenerative diseases, including Parkinson's, Alzheimer's, multiple sclerosis, amyotrophic lateral sclerosis, and AIDS dementia. Microglia are the resident macrophages of the central nervous system and are the cells primarily responsible for the inflammatory component of these diseases.", 'Using gene expression profiling, we compared the profile of the neurospecific microglial cell line BV-2 after LPS stimulation to that of a macrophage cell line (J774A.1) stimulated with LPS.', 'A set of 77 genes that were modulated only in microglial cells after LPS stimulation was identified. One gene of interest, Gng12, was investigated further to determine its ability to modify the inflammatory response. Specifically, Gng12 mRNA levels were transiently increased after LPS stimulation. In addition, overall levels of Gng12 mRNA after LPS stimulation were significantly higher in BV-2 cells as compared to macrophage cells.
