In the appropriate clinical setting, any of these mechanisms might increase effective renal plasma flow and thus increase urine output.

What in fact is calculated is the effective renal plasma flow (eRPF).

In practice, PAH clearance is used instead to calculate the effective renal plasma flow (eRPF).

No significant alteration of glomerular filtration rate, effective renal plasma flow, total renal resistances, or filtration fraction was observed between or within the groups.

Effective renal plasma flow (eRPF) is a measure used in renal physiology to calculate renal plasma flow (RPF) and hence estimate renal function.

The MAG3 clearance is highly correlated with the effective renal plasma flow (ERPF), and the MAG3 clearance can be used as an independent measure of renal function.

The filtration fraction was calculated by dividing glomerular filtration rate by effective renal plasma flow, and total renal resistances by dividing the mean arterial pressure (obtained by an automatic device during tracer infusion) by effective plasma flow.

Deadline for submission is April 8; again,Ms. Erpf has the details.

With the raw spaces gone, this year's open studios exhibition, curated by Rosemary Erpf, is more orderly.

Community Counselling said that Mr. Erpf had violated the terms of a confidentiality agreement.

Mr. Erpf graduated from Columbia University, where he is now taking premedical courses.

What in fact is calculated is the effective renal plasma flow (eRPF).

Erpf is a river of Baden-Württemberg, Germany.

Ms. Erpf said that she had considered commissioning work from an artist the representatives liked to avoid problems like an inappropriate size, but there was a risk.

Mr. Erpf acknowledged that he had signed a confidentiality agreement with his employer at the time but said he had done nothing wrong.

Initially, the undertaking was financed partly by Armand Erpf, the Wall Street financier.

"I know this isn't for the reception area, but I wanted you to see it for later consideration," Ms. Erpf said.

"If they want to look at price controls, they should look into the whole price structure of works of art," Ms. Erpf said.

Following Ms. Erpf's tightly arranged schedule the group headed across the county to Dobbs Ferry.

Rosemary Cohane Erpf, curator of the show, chose the theme after viewing works in numerous slide registries, museums, galleries and studios.

In practice, PAH clearance is used instead to calculate the effective renal plasma flow (eRPF).

"The A.C.L.U. isn't doing anything inappropriate in its research," Mr. Erpf said, adding that he did not have any direct knowledge of current data collection.

This margin of error is generally acceptable considering the ease with which PAH infusion allows eRPF to be measured.

To round up artwork for the pair to choose from, the council enlisted Rosemary Erpf, an art consultant and art history professor who lives in New York City.

Before coming face to face with the works Ms. Erpf had selected, Ms. Summers and Mr. Smargon had seen them on slides.

ON a bright but chilly Monday morning Ms. Summers and Mr. Smargon set off on on a field trip led by Ms. Erpf.

Tina Potter R. C. Erpf Gallery 568 Broadway, at Prince Street Through Oct. 3 The 17 photomontages in this show are an unexpected delight.

"It creates a psychological barrier that inhibits the viewer from reacting to work on its own merits," said Rosemary Erpf, the director of the SoHo Gallery that bears her name.

Ms. Erpf steered her clients into a neighboring studio, that of Michael Torlen, a landscape painter from Mamaroneck, where the group admired a small painting of a rich orange sunset.

Ms. Erpf, Ms. Summers and Mr. Smargon frequently injected, "I'm just playing devil's advocate," into their discussions about the merits and appropriateness of the work presented to them.

Effective renal plasma flow (eRPF) is a measure used in renal physiology to calculate renal plasma flow (RPF) and hence estimate renal function.

Ms. Erpf said that for the next step, "We will continue to select works for the seventh floor working with the installation - where things go and how they will relate to other pieces in the collection.
