The authors investigated the effect of adenosine or ATP on narrow QRS tachycardia in 56 pts, 3 pts with wide QRS tachycardia 9 pts with suspected latent preexcitation and 10 pts with PVC suspected to be ventricular parasystole. After the bolus iv. administration of adenosine or ATP every SVT was stopped related to AV node (44 pts), but in the rest twelve related to atrial origin of SVT only one...
Though the OFDM provides high data rate due to its high spectral efficiency, it has high PAPR which results in performance degradation and high out of band radiation due to nonlinearity of the high power amplifier. Partial Transmit sequence is one of the distortions-less PAPR reduction techniques which obtain the minimum PAPR signal by multiplying suitable phase factors with subsequenced subcar...
A low-complexity partial transmit sequence (PTS) technique for reducing the peak-to-average power ratio (PAPR) of an orthogonal frequency division multiplexing (OFDM) system is presented. However, PTS technique requires an exhaustive search over all combinations of allowed phase weighting factors, and the search complexity increases exponentially with the number of sub-blocks in OFDM system. He...
3563 Background: Molecular tumor profile assays (MTP) may predict the primary site of origin in CUP, but the impact of site-specific therapy on outcomes is undefined. Accurate identification of CUP patients (pts) with a colorectal site of origin would be expected to improve treatment results by directing the use of colorectal cancer regimens rather than empiric CUP regimens. METHODS We identi...
7036 Background: Single agent docetaxel, 75 mg/m2 every 3 weeks given second line improves survival compared with other chemotherapeutic regimens or best supportive care in advanced NSCLC. This multicentre phase III study was initiated to compare standard 3-weekly docetaxel with weekly docetaxel as second-line therapy for advanced NSCLC. METHODS Patients (pts) with stage IIB-IV NSCLC were ran...
BACKGROUND Phrenic nerve stimulation (PNS) and high pacing thresholds (HPT) hinder biventricular stimulation in patients (pts) undergoing cardiac resynchronization therapy (CRT). A new quadripolar left ventricular (LV) lead (Quartet 1458Q, St. Jude Medical) with increased number of pacing configuration, might overcome this problem. METHODS All consecutive pts in whom a standard bipolar lead i...
Distortion product otoacoustic emissions (DPOAE), permanent threshold shifts (PTS) and outer hair cell (OHC) losses were analyzed in a population of 187 noise-exposed chinchillas to determine the predictive accuracy (sensitivity and specificity) of the DPOAE for PTS and OHC loss. Auditory evoked potentials (AEP) recorded from the inferior colliculus of the brainstem were used to estimate hearin...
The partial transmit sequences (PTS) scheme achieves an excellent peak-to-average power ratio (PAPR) reduction performance of orthogonal frequency division multiplexing (OFDM) signals at the cost of exhaustively searching all possible rotation phase combinations, resulting in high computational complexity. Several researchers have proposed using binary-coded genetic algorithms (BGA) PTS to redu...
BACKGROUND The validation of sample stability through pneumatic tube system (PTS) is essential. The objective of this study was to evaluate the effects of PTS transportation on laboratory results. METHODS Paired EDTA and SST blood samples were collected from 56 randomly selected patients. Laboratory parameters were compared between PTS group and hand-delivered group. RESULTS No statistical ...
Methods Patients (pts) from TENDER were included if baseline and wk 6 fasting insulin were measured. Glucocorticoid tapering was not permitted until wk 6. Insulin sensitivity was quantified using the homeostatic model of insulin resistance (HOMA-IR). Pts were classified as having IR if their HOMA-IR was ≥2.2 U. Change in HOMA-IR after 6 wks was assessed using paired t-test. Baseline association...
