Current multicast routing protocols have not been designed for mobile nodes and especially roaming sources. Using the remote subscription as basis, we develop a new approach based on a new entity called Mobility-aware Rendezvous Point (MRP) to hide the mobility of a mobile multicast source from the main multicast delivery tree and offer an optimal routing. The key idea of this work is to make t...

Mitogen-regulated proteins (also known as proliferin; mrp/plf) are nonclassical members of the PRL/GH family. They are expressed at high levels during midgestation when they are thought to induce angiogenesis and uterine growth. There are between four and six mrp/plf genes, and three different complementary DNAs have been cloned. Here we identify a fourth mrp/plf gene (mrp4) that we have cloned...

The purpose of this study was to retrospectively study 48 patients with infiltrating ductal breast cancer to evaluate the relationship between the degree of accumulation of technetium-99m methoxyisobutylisonitrile (Tc-MIBI) and P-glycoprotein (Pgp) or multidrug resistance-related protein (MRP) expression in breast cancer tissues. Before surgery or biopsy, all 48 patients underwent scintimammogr...

The intracellular site of synthesis of mitochondrial ribosomal proteins (MRP) in Neurospora crassa has been investigated using three complementary approaches. (a) Mitochondrial protein synthesis in vitro: Tritium-labeled proteins made by isolated mitochondria were compared to (14)C-labeled marker MRP by cofractionation in a two-step procedure involving isoelectric focusing and polyacrylamide ge...

Human cells can become multidrug resistant (MDR) by an increase in the activity of the MDR1 P-glycoprotein or by other, as yet unknown mechanisms, referred to as non-P-glycoprotein mediated MDR (non-Pgp MDR). S. P. C. Cole et al. [Science (Washington DC), 258: 1650-1654, 1992] recently reported that in two cell lines non-Pgp MDR was associated with the overexpression of a new putative membrane ...

Amplification of the gene encoding multidrug resistance-associated protein (MRP) and overexpression of its cognate mRNA have been detected in multidrug-resistant cell lines derived from several different tumor types. To establish whether or not the increase in MRP is responsible for drug resistance in these cell lines, we have transfected HeLa cells with MRP expression vectors. The transfectant...

In this study we report that the multidrug resistance protein (MRP) transports calcein from the cytoplasmic compartment of tumor cells, in contrast to P-glycoprotein which transports calcein acetoxymethyl ester from the plasmamembrane. The transport of calcein by MRP is ATP-dependent and is inhibited by probenecid and vincristine. Intracellular glutathione (GSH) depletion which occurred when ce...

The efficiency of ERP is usually depressed because current algorithms, which just consider product requirement and stock factors but do not take whole correspondence between productive situation and resource into account, make CRP built on MRP and the resource of enterprise inconsistent so that MRP need be rebuilt. This paper takes integrated optimization of MRP and CRP as research intention, b...

This paper presents a novel matched rotation precoding (MRP) scheme to design a rate one space-frequency block code (SFBC) and a multirate SFBC for MIMO-OFDM systems with limited feedback. The proposed rate one MRP and multirate MRP can always achieve full transmit diversity and optimal system performance for arbitrary number of antennas, subcarrier intervals, and subcarrier groupings, with lim...
