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.

MRI of tissues with rapid transverse relaxation can be performed efficiently using the zero echo time (ZTE) technique. At high bandwidths leading to large relative initial radiofrequency (RF) dead times, the method becomes increasingly sensitive to artifacts related to signal stemming from outside the field of view, particularly from the RF coils. Therefore, in this work, a birdcage coil was designed that is virtually free of 1H signal.', 'A transmit-receive birdcage RF coil for MRI of joints at 7T was designed by rigorously avoiding materials containing 1H nuclei, by using purely mechanical connections without glue, and by spoiling of unwanted signal by application of ferromagnetic materials. The coil was tested for residual 1H signal using ZTE phantom and in vivo joint imaging.', 'In standard ZTE imaging, no 1H signal was detected above noise level. Only at extreme averaging, residual signal was observed close to conductors associated with 1H-containing molecules at adjacent glass surfaces. Phantom images with dead times up to 3.8 Nyquist dwells were obtained with only negligible background artifacts. Furthermore, high-quality ZTE images of human joints were acquired.

More than 90% of anal condyloma is attributed to nonhigh risk strains of human papillomavirus (HPV), thus patients with anal condyloma do not necessarily undergo HPV serotyping unless they are immunocompromised (IC). We hypothesized that IC patients with anal condyloma have a higher risk of high-risk HPV and dysplasia than nonimmunocompromised (NIC) patients.', 'We performed a retrospective chart review of patients who underwent surgical treatment by a single surgeon for anal condyloma from 1/2000 to 1/2012. HPV serotyping was performed on all patient samples. We compared incidence of high-risk HPV and dysplasia in condyloma specimens from IC and NIC patients.', 'High-risk HPV was identified in 14 specimens with serotypes 16, 18, 31, 33, 51, 52, and 67. Twenty-two cases (18.3%) had dysplasia. Invasive carcinoma was identified in one IC patient. The prevalence of dysplasia or high-risk HPV was not significantly different between IC and NIC groups. High-risk HPV was a significant independent predictor of dysplasia (odds ratio [OR] = 5.2; 95% CI = 1.24-21.62). Immune status, however, was not a significant predictor of high-risk HPV (OR = 1.11; 95% CI = 0.16-5.12) nor dysplasia (OR = 0.27; 95% CI = 0.037-1.17).

Trials with healthy volunteers have shown that emergency ambulance transportation induces stress, which becomes evident by an increase in heart rate, blood pressure and plasma levels of stress hormones such as adrenaline, noradrenaline, cortisol and prolactin. A study was undertaken to test the hypothesis that emergency ambulance transportation may also lead to stress in patients with acute coronary syndrome.', 'Venous plasma levels of epinephrine, norepinephrine and lactate as well as visual analogue scale (VAS) scores for pain and anxiety were measured in 32 patients with defined clinical signs of acute coronary syndrome before and after transportation. Heart rate, blood pressure and transcutaneous oxygen saturation levels were recorded every 3 min.', 'Mean (SD) plasma levels of epinephrine and norepinephrine increased significantly (p<0.01) during transportation (159.29 (55.34) ng/l and 632.53 (156.32) ng/l before transportation vs 211.03 (70.12) ng/l and 782.93 (173.95) ng/l after transportation), while lactate levels, heart rate and mean blood pressure remained almost stable. There was no significant change in mean (SD) VAS scores for pain and anxiety (3.79 (3.70) and 2.89 (3.01) vs 2.13 (3.30) and 1.57 (2.78)).
