Quantifying the preferred transition speed (PTS) from walking to running has provided insight into the underlying mechanics of locomotion. The dynamic similarity hypothesis suggests that the PTS should occur at the same Froude number across gravitational environments. In normal Earth gravity, the PTS occurs at a Froude number of 0.5 in adult humans, but previous reports found the PTS occurred a...

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...

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...

Results 862 pts (63±10y, 69% male); 57% OPCAB. Median ES II=1,12%; ES I=2,45%. Observed mortality was 2,9%. OPCAB pts had lower glucose, higher ejection fraction, less previous surgeries, less LMCA lesions, smaller bleeding and less distal anastomosis (3,2±1,2 x 3,8±1,0, p<0,001). They had similar use of LITA (89,8% x 86,2%, p=0,102) and complete revascularization (94,9% x 94,5%, p=0,820). In b...

PURPOSE The present study aimed to assess the efficacy and tolerability of rufinamide as adjunctive drug for the treatment of a large series of children, adolescents and adults with refractory cryptogenic or symptomatic focal epilepsy. METHODS Patients were recruited in a prospective, add-on, open-label treatment study from six Italian and one German centers for pediatric and adolescent epile...

Background: Hepatocellular carcinoma (HCC) is a hypervascular tumor. Metronomic chemotherapy; the continuous administration of low-dose chemotherapy; has both cytotoxic and antiangiogenic effects with low toxicity profile. We evaluated the efficacy and toxicity of metronomic capecitabine (MC) in patients with advanced HCC. Patients and Methods: From May 2010, we enrolled pts with either metasta...

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, ...
