The purpose of this investigation was to improve the accuracy of measurement of thermal right ventricular ejection fraction (RVEF) using the modified Swan-Ganz catheter. Three serial ejection fractions (EFs) (EF1, 2, 3) and the mean were calculated, based on Holt's theory. RVEFs were compared between right ventricular (RV) and atrial (RA) injection in ten intensive care unit (ICU) patients usin...

We study the problem of fair and efficient allocation a set indivisible goods to agents with additive valuations using popular fairness notions envy-freeness up one good (EF1) equitability (EQ1) in conjunction Pareto-optimality (PO). There exists pseudo-polynomial time algorithm compute an EF1+PO allocation, non-constructive proof existence allocations that are both EF1 fractionally Pareto-opti...

Unlike milk-based infant formulas, soy-based infant formulas containing supplemental fructooligosaccharides (FOS) have not been clinically evaluated. A randomized, double-blind, 28 day parallel feeding trial compared gastrointestinal (GI) tolerance and hydration in healthy term newborn infants fed either a commercialized soy formula (with history of safe use) containing sucrose as 20% of total ...

Impaired shortening deactivation of cardiac myocytes could sustain myocardial contraction, preserving ejection fraction at the expense of diastolic dysfunction. We examined the relationship between first-phase ejection fraction (EF1), the fraction of left ventricular volume ejected from the start of systole to the time of the first peak in left ventricular pressure (corresponding to the time of...

Specific human chromosomal elements enhance the performance of episomal gene-transfer vectors. S/MAR-based episomal vector pEPI-eGFP transfects CD34+ haematopoietic cells, but only transiently. To address this issue we reinforced (1) transgene transcription by replacing the CMV promoter driving eGFP with the EF1/HTLV or SFFV promoters to produce vectors pEPI-EF1/HTLV and pEPI-SFFV, respectively...

Envy-freeness up to one good (EF1) and envy-freeness any (EFX) are two well-known extensions of for the case indivisible items. It is shown that EF1 can always be guaranteed agents with subadditive valuations. In sharp contrast, it unknown whether or not an EFX allocation exists, even four additive addition, best approximation guarantee (φ − 1) ≃ 0.61 by Amanitidis et al.. order find a middle g...

Bonamia ostreae is an intrahaemocytic protozoan affecting Ostrea edulis. The parasite multiplies within haemocytes without being degraded and involves changes in cellular activities. Studies aiming at better understanding host response to a pathogen at the transcriptome levels are frequently based on the use of real time PCR assays, which require some reference genes. However, very few sequence...

Contact electrification between two different materials is one of the oldest fields of study in solid-state physics. Here, we introduced an innovative system based on optical electric-field-induced second harmonic generation (EFI-SHG) technique that can directly monitor the dynamic performance of the contact electrification on the surface of polyimide film. After the contact, the EFI-SHG system...

Reverse transcription-qPCR (RT-qPCR) has become a popular method for gene expression studies. Its results require data normalization by housekeeping genes. No single gene is proved to be stably expressed under all experimental conditions. Therefore, systematic evaluation of reference genes is necessary. With the aim to identify optimum reference genes for RT-qPCR analysis of gene expression in ...

ATP hydrolysis by the isolated F1-ATPase drives the rotation of the central shaft, subunit , which is located within a hexagon formed by subunits ( )3. The C-terminal end of forms an -helix which properly fits into the “hydrophobic bearing” provided by loops of subunits and . This “bearing” is expected to be essential for the rotary function. We checked the importance of this contact region by ...
