Function and regulation of Rnd proteins
Nature Reviews Molecular Cell Biology, 2006The Rnd proteins, which form a distinct sub-group of the Rho family of small GTP-binding proteins, have been shown to regulate the organization of the actin cytoskeleton in several tissues. In the brain, they participate in neurite extension, whereas in smooth muscle, they modulate contractility.

Computer simulations of the activity of RND efflux pumps
Research in Microbiology, 2018 The putative mechanism by which bacterial RND-type multidrug efflux pumps recognize and transport their substrates is a complex and fascinating enigma of structural biology. How a single protein can recognize a huge number of unrelated compounds and transport them through one or just a few mechanisms is an amazing feature not yet completely unveiled ...

RND efflux pumps in Gram-negative bacteria; regulation, structure and role in antibiotic resistance
Future Microbiology, 2020 Rresistance-nodulation-division (RND) efflux pumps in Gram-negative bacteria remove multiple, structurally distinct classes of antimicrobials from inside bacterial cells therefore directly contributing to multidrug resistance.

The hydrophobic trap—the Achilles heel of RND efflux pumps [PDF]
Research in Microbiology, 2018 Resistance-nodulation-division (RND) superfamily efflux pumps play a major role in multidrug resistance (MDR) of Gram-negative pathogens by extruding diverse classes of antibiotics from the cell. There has been considerable interest in developing efflux pump inhibitors (EPIs) of RND pumps as adjunctive therapies.

Evaluation of Different Metaheuristics Solving the RND Problem
2007RND (Radio Network Design) is a Telecommunication problem consisting in covering a certain geographical area by using the smallest number of radio antennas achieving the biggest cover rate. This is an important problem, for example, in mobile/cellular technology. RND can be solved by bio-inspired algorithms. In this work we use different metaheuristics

RND's Ethernet brouter family — an inside look
Computer Communications, 1989Abstract The growth of Local Area Networks has generated a proliferation of devices that interconnect and extend LANs. Network administrators must decide between a wide variety of inter-LAN devices, the most popular of these being the bridge and the router.

On Improvement of the DV-RND Localization in Wireless Sensor Networks
2015 IEEE 12th Intl Conf on Ubiquitous Intelligence and Computing and 2015 IEEE 12th Intl Conf on Autonomic and Trusted Computing and 2015 IEEE 15th Intl Conf on Scalable Computing and Communications and Its Associated Workshops (UIC-ATC-ScalCom), 2015This paper studies how to improve the DV-RND localization [1], a newly proposed range-free localization algorithm, via boundary compensation and anchor selection in a uniformly deployed wireless sensor network. We first present a boundary compensation algorithm, aiming at reducing the impact of boundary effect.

The real scalar field in extreme RNdS space
General Relativity and Gravitation, 2005Here the real scalar field equation between the outer black hole horizon and the cosmological horizon is solved in the extreme Reissner-Nordström-de Sitter space. The authors use the polynomial approximation with the goal to solve the wave equation and the first limiting case is discussed in detail. Additionally the case where the two horizons are very

Expression of RND proteins in human myometrium.
Biology of reproduction, 2007RHO GTPases are key regulators of the actin cytoskeleton and stress fiber formation. In the human uterus, activated RHOA forms a complex with RHO-associated protein kinase (ROCK) which inhibits myosin light chain phosphatase (PPP1R12A), causing a calcium-independent increase in myosin light chain phosphorylation and tension (Ca2+ sensitization ...
