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: To determine whether anxiety and depression are associated with greater respiratory discomfort in asthma.', 'Adults with asthma (n = 230) underwent methacholine (Mch) challenge. Anxiety and depression, asthma control, and quality of life were evaluated at study entry by using the Hospital Anxiety and Depression Scale, Asthma Control Test, and Asthma Quality of Life Questionnaire, respectively. Qualitative descriptors of breathlessness, dyspnea intensity (modified Borg scale and visual analog scale [VAS]), and other respiratory symptoms were evaluated before and after Mch challenge.', 'Patients were classified as neither anxiety nor depression (NAD), anxiety only, depression only (D), or both anxiety and depression (AD) according to the Hospital Anxiety and Depression Scale score. Asthma Control Test and Asthma Control Test, and Asthma Quality of Life Questionnaire scores were lowest in the AD group (both p < 0.001). VAS scores for dyspnea and wheezing before Mch challenge were highest in the AD group (both p < 0.05). The increase in the modified Borg scale score after Mch challenge was higher in the AD group (mean [standard deviation] 2.5 ± 2.0) than in the NAD (1.5 ± 1.5) and D (0.8 ± 0.9) groups (p = 0.006 and p = 0.003, respectively). Most descriptors of breathlessness were more prevalent in the anxiety only, D, and AD groups than in the NAD group. Multivariable logistic regression models indicated that anxiety increased the risk of dyspnea (odds ratio 1.10, p < 0.001 for the Borg score; odds ratio 3.84, p = 0.032 for the VAS score) but not for other respiratory symptoms.

Q: Inhalation of nitric oxide (NO) and inhibition of phosphodiesterase type 5 (PDE5) selectively dilate the pulmonary circulation in patients with acute lung injury (ALI) associated with pulmonary hypertension. PDE5 inhibitors administered at doses that decrease pulmonary artery pressures have been shown to worsen arterial oxygenation. We investigated the efficacy of doses of PDE5 inhibitors that do not reduce pulmonary artery pressure alone (subthreshold doses) to improve the response to inhaled NO in an animal model of ALI.', 'Adult Sprague-Dawley rats were pre-treated with 0.5 mg/kg Escherichia coli 0111:B4 endotoxin and 16 to 18 h later, their lungs were isolated perfused and ventilated. The thromboxane mimetic U46619 was used to induce pulmonary hypertension. After the determination of subthreshold doses of two different PDE5 inhibitors, either 50 microg zaprinast or 10 ng sildenafil was added to the perfusate and the decrease of pulmonary artery pressure measured in the presence and absence of inhaled NO.', 'In the presence of 4 or 10 ppm NO, zaprinast (-1.6 +/- 0.4 and -2.9 +/- 0.6 mmHg, respectively) and sildenafil (-1.9 +/- 0.4 and -2.4 + 0.3 mmHg, respectively) improved responsiveness to inhaled NO compared to lungs from rats treated with LPS only (0.7 +/- 0.1 and -1.0 +/- 0.1 mmHg, respectively; P<0.05). Neither zaprinast nor sildenafil prolonged the pulmonary vasodilatory response to inhaled NO.

Q: To determine the antibiotic resistance patterns of pathogenic Escherichia coli on goat meat carcass at Huruma and Kiserian abattoirs in Kenya.', 'Laboratory based study.', 'Huruma and Kiserian abattoirs in Kenya,', '400 slaughtered goats inspected by veterinary health officers and approved for human consumption.', 'A Total of 400 slaughtered goats which were inspected by veterinary health officers and approved for human consumption were sampled from Huruma and Kiserian abattoir. Goat carcass swabs were collected by passing each swab tissue on four parts of the carcass mainly neck, right and left forelimbs, right and left hind limbs, and brisket.', 'A total of 54 E. coli isolates were isolated and confirmed to be pathogenic. The percentage of isolates resistant to various microbial agents was recorded as follows: ampicillin (26 %), amoxycillin-clavulanic acid (17%), tetracycline (15%), chroramphenicol (4%), and ceftrixone (2% each). All Escherichia coli isolates were susceptible to gentamicin sulphamethaxazole-trimethomprin, kanamycin, cetriazididine (CAZ, 30pg), ciproxacin, nalidixic acid and chloramphenicol. Isolates were resistant to one or more of the antibiotics tested. Among the drugs tested, resistance was more frequently observed against ampicillin, amoxycillin-clavulanic acid, tetracycline, ceftrixone and chroramphenicol antibiotics. Among the isolates 26(48%) were positive for the stx1 gene, 19(35%) had the eae gene, 10(19%) possessed est gene,while 8(15%) harboured elt gene. Overall five isolates (10%) possessed aspu gene and two (4%) had aggR gene. No isolate possessed ipah gene.
