Introduction: Noninvasive positive pressure ventilation (NIPPV) has become an integral tool in the management of acute hypercapnic respiratory failure (AHRF) in chronic obstructive pulmonary disease (COPD). This study was performed to evaluate the early effects of NIPPV on pulmonary artery pressure (PAP), serum N-terminal pro BNP (NT-proBNP), and ventilatory parameters in the COPD patients with...

INTRODUCTION Several reports confirmed the prognostic value of the N-terminal fragment of B-type natriuretic peptide prohormone (NT-proBT) in various patient populations. Patients with medical indications for implantation of an artificial cardiac pacemaker are at high risk of cardiovascular events. There is limited data assessing the prognostic value of NT-proBNP in this group. OBJECTIVES The...

OBJECTIVES To describe characteristics associated with neurotoxicity (NT) in advanced ovarian cancer patients treated on Gynecologic Oncology Group 218 and examine effect of substituting docetaxel for paclitaxel in these patients. METHODS The development of NT was defined as Common Toxicity Criteria grade (G)≥1. The association between substitution with docetaxel and NT improvement was explor...

Production and clearance of plasma C-type natriuretic peptide (CNP) and amino terminal (NT)-proCNP immunoreactivity in the human circulation remain poorly characterized. Accordingly, we have measured arterial and venous concentrations of CNP and NT-proCNP across multiple tissue beds during cardiac catheterization in 120 subjects (age: 64.2+/-9.0 years; 73% men) investigated for cardiovascular d...

A single dose of typical neuroleptic, haloperidol, has been demonstrated to increase the expression of neurotensin/neuromedin N (NT/N) mRNA in the dorsolateral striatum within 1 hr of its administration (Merchant et al., 1991). The present study further investigated neuroleptic-induced regulation of NT/N gene transcription. Levels of NT/N mRNA were examined at various times following a single d...

In the long-term evolution (LTE) system, channel equalization makes compensation to restore the original signal, the paper puts forward iteration sphere decoding algorithm which combines traditional sphere decoding and the improved QR based on the conventional QR decomposition detection algorithm. It can effectively reduce the system complexity. At the same time, in QPSK and 16QAM, the simulati...
