Fourier transform of gated radionuclide ventriculograms (RNV) permits the quantitative evaluation of regional wall motion abnormalities (RWMA) regarding both regional magnitude (amplitude display) and regional time sequence of contraction (phase display). In this study, an attempt was made to further specify coronary artery disease (CAD) and non-CAD RWMA detected on consecutive exercise RNV in ...

abstract background: the optimal therapy of acute iliofemoral venous thrombosis is still a matter of debate. the purpose of our study was to evaluate the late results of iliofemoral thrombectomy with regard to the prevention of the development of a post thrombotic syndrome (pts). methods: during 2000-2003, 18 patients underwent transfemoral venous thrombectomy for acute iliofemoral venous throm...

BACKGROUND Stress-induced/Takotsubo cardiomyopathy (TC) is an increasingly recognized diagnostic entity. OBJECTIVE This study was aimed to assess the prevalence and clinical predictors of short and long-term outcome of patients (pts) diagnosed with TC. METHODS We included all consecutive pts admitted in our department, from November 2006 to August 2011, who met the Mayo Clinic criteria for ...

Apical growth in pollen tubes (PTs) is associated with the presence of tip-focused ion gradients and fluxes, implying polar localization or regulation of the underlying transporters. The molecular identity and regulation of anion transporters in PTs is unknown. Here we report a negative gradient of cytosolic anion concentration focused on the tip, in negative correlation with the cytosolic Ca(2...

According to previous reports, Lactococcus lactis imports glucose via two distinct phosphoenolpyruvate:phosphotransferase systems (mannose-PTS and cellobiose-PTS) and one or more unknown non-PTS permease(s). GlcU was identified as the sole non-PTS permease involved in the transport of glucose. Additionally, the biochemical properties of PTS(Man), PTS(Cel) and GlcU were characterized in double k...

The application of metabolic engineering in Escherichia coli has resulted in the generation of strains with the capacity to produce metabolites of commercial interest. Biotechnological processes with these engineered strains frequently employ culture media containing glucose as the carbon and energy source. In E. coli, the phosphoenolpyruvate:sugar phosphotransferase system (PTS) transports glu...

A peak-to-average power ratio (PAPR) reduction method for an orthogonal frequency division multiplexing (OFDM) system based on a combination of a partial transmit sequence (PTS) scheme with the backtracking search optimization algorithm (BSA) is proposed. The PTS scheme shows good PAPR reduction performance; however, it requires a complex computation to search the set of optimum phase factors, ...

Preferential sugar utilization is a widespread phenomenon in biological systems. Glucose is usually the most preferred carbon source in various organisms, especially in bacteria where it is taken up via the phosphoenolpyruvate:sugar phosphotransferase system (PTS). The currently proposed model for glucose preference over non-PTS sugars in enteric bacteria including E. coli is strictly dependent...

BACKGROUND Appraisal and coping following a disaster are important factors in children's post-traumatic stress (PTS) symptoms. However, little is known about predictors of disaster coping responses. This study examined stress-load, appraisals and coping styles measured prior to the September 11 terrorist attacks as predictors of 9/11-specific appraisals, coping and PTS. METHODS A community sa...

Results: The average vaccination differences from pre-intervention to the intervention year were significantly larger in the intervention arm (n1⁄410 practices) than the control arm (n1⁄410 practices); for children aged 9–18 years (11.1 pct pts intervention vs 4.3 pct pts control, po0.05); for non-white children (16.7 pct pts intervention vs 4.6 pct pts control, po0.001); and overall (9.9 pct p...
