AIMS Actual resuscitation guidelines recommend 10 respirations per minute (rpm) for advanced pediatric life support. This respiratory rate (RR) is much lower than what is physiological for children. The aim of this study is to compare changes in ventilation, oxygenation, haemodynamics and return of spontaneous circulation (ROSC) rates with three RR. METHODS An experimental model of asphyxial ...

BACKGROUND Rotational atherectomy with the Rotablator catheter has improved percutaneous treatment of certain coronary atherosclerotic lesions, but the "no-reflow" phenomenon remains a serious complication. Because platelet activation by rotablation may contribute to the no-reflow phenomenon, we developed an in vitro system to test the effect of rotablation on platelets in the absence or presen...

PURPOSE There is a need for new technologies to study tissue-based biomarkers. The current gold standard, immunohistochemistry, is compromised by variability in tissue processing and observer bias. Reverse transcription-PCR (RT-PCR), immunocytochemistry, and reverse-phase lysate microarrays (RPM) are promising alternative technologies but have not yet been validated, or correlated, on the same ...

The paper revisits the conventional wisdom according to which vertical restrictions on retail prices help upstream firms to collude. We analyze the scope for collusion with and without resale price maintenance (RPM) when retailers observe local shocks on demand or retail costs. In the absence of RPM, retail prices react to retailers’ information and deviations from collusive behavior are thus d...

the intension in this work is to investigate the effect of different bending manifold pipes on engine performance for different engine speed. Power, Torque, and BSFC were calculated and presented to show the effect of varying bending pipes angles on them for all cases considered. A special program used to carry out the calculations. A simulation model for 4-cylinders spark ignition engine with ...

The Supreme Court’s recent decision in Leegin Creative Leather Products, Inc. v. PSKS, Inc., which replaced the longstanding per se rule against resale price maintenance (RPM) with a rule of reason approach, has resurrected the debate over RPM. Legal and economic proponents of this practice again point to its potential procompetitive benefits, while RPM detractors emphasize its possible anticom...

BACKGROUND Administration of topical rapamycin (RPM) suppresses the regeneration and revascularization of photocoagulated blood vessels induced by pulsed dye laser (PDL). OBJECTIVE To systematically elucidate the molecular pathophysiology of the inhibition of PDL-induced angiogenesis by topical RPM in a rodent model. METHODS The mRNA expression profiles of 86 angiogenic genes and phosphoryl...

An upstream manufacturer can use minimum resale price maintenance (RPM) to exclude potential competitors. RPM lets the incumbent manufacturer transfer profits to retailers. If entry is accommodated by retailers, upstream competition leads to fierce downstream competition and the breakdown of RPM. Thus, via RPM, retailers internalize the effect of accommodating entry on the incumbent’s profits. ...
