[rho]-compact groups as framed manifolds
We describe a natural way to associate to any [rho]-compact group an element of the [rho]-local stable stems, which, applied to the [rho]-completion of a compact Lie group G, coincides with the element represented by the manifold G with its left-invariant framing. To this end, we construct a …

Rho GTPases in Neuronal Apoptosis and Neurodegeneration
<p>Several studies have identified Rho family GTPases (i.e. Rho, Rac, Cdc42) as mediators of diverse critical cellular processes, such as actin cytoskeleton remodeling, gene transcription, cell-cell adhesion, and cell cycle progression. However, more recent data highlight an essential role for Rho …

Photoproduction of [rho]⁰ Mesons on complex nuclei
An experiment was performed on the reaction y + A + A + p0 + A + [pi]+ + [pi]- the DESY 7.5 GeV electron synchrotron. Using a double arm magnetic spectrometer, approximately 106 dipion events were detected on thirteen complex nuclei covering a range from Beryllium to Uranium. The events were in a …

Rho GTPase Signaling Modulates Neurotransmission in Caenorhabditis elegans
Rho family GTPases act as molecular switches in the regulation of diverse cellular functions, including cell division, gene transcription and neurotransmission. In the model organism Caenorhabditis elegans, the Kalirin and Trio ortholog UNC-73 contains two RhoGEF domains that specifically activate …

Reconstitution Of Rho Gtpase Interactions At The Membrane
… signal with a robust morphological change. The Rho Family of GTPases play critically important roles in mediating these cellular processes. However, in order for the Rho GTPases to help regulate these processes in a tightly coordinated spatial and temporal manner, they need to be properly …

B [right arrow] ([rho]/[omega]) [gamma] at BaBar
… electroweak penguin decays B [right arrow] ([rho]/[omega]) [gamma] at the asymmetric energy e+e- PEP-II collider with the BABAR detector. Together with the previously measured branching fractions of the decays ... the ratio of CKM-matrix elements Vtd=Vts are extracted and the length of the far …

Characterization of Vibrio VopS, an AMPylator of Rho GTPases
… Our studies have found that VopS inhibits Rho GTPase signaling during infection by directly modifying Rho, Rac, and Cdc42, preventing their interaction with downstream effectors. These observations reveal a unique activity for VopS, which targets a pathway that is critical in the cellular …

High energy photoproduction of rho and phi vector mesons
We have studied the photoproduction of p and phi vector mesons from hydrogen in the Fermilab broad band neutral beam. Forward going two particle final states were detected in a multiparticle spectrometer consistIng of two analyzing magnets, a multiwire-proportional-chamber tracking system and a …

Methanol amination over hydrothermally treated zeolites RHO and Modernite
… improved selectivity to DMA, include zeolites Rho, ZK-5 and Chabazite. In addition, certain forms of hydrothermally treated Mordenite can produce nonequilibrium product distributions. The performance of Rho can also be improved with hydrothermal treatment. The objectives of this study were …

Regulation of Blood Vessel Development via Rho Family GTPase Signaling
The Rho family of small GTPases has been shown to be required in endothelial cells (ECs) during blood vessel formation. However, the underlying cellular events controlled by different GTPases remain unclear. Here, we assess the cellular mechanisms by which Rho family GTPase proteins and their …

Alteration of prenylation: Effect on neurite outgrowth and Rho GTPase signaling
… inhibition of prenylation precursors that alter Rho GTPase localization and loading of GTP. We show here that lovastatin decreases neurite initiation and concurrently increases GTP loading of RhoA in the cytosol and decreases GTP loading of Racl associated with the plasma membrane. We also assess …

Regulation des Neuritenwachstums durch Rho-GTPasen in primärkultivierten Hippocampusneuronen der Ratte
… Hefe bis zum Menschen sind kleine GTPasen der Rho Subfamilie, <br>sowie ihre Effektoren wesentlich beteiligt. So führt in einer Anzahl von neuronalen <br>Zellmodellen die Hemmung von Effektoren der kleinen GTPase Rho zu einem <br>Auswachsen von Neuriten. Unbekannt war bislang, ob dieses …

Transcription termination by bacteriophage T7 RNA polymerase at rho-independent terminators
To investigate the mechanism of transcription termination by bacteriophage RNA polymerases, templates encoding variants of the transcription-termination structure in the regulatory region of the threonine (thr) operon of Escherichia coli were used. The thr terminator comprises two distinct …

Measurement of the Michel Parameter Rho Using the MEGA Positron Spectrometer
… attempts to measure the Michel parameter Rho in normal muon decay Mu to e nu_{e} nu_{mu} with a precision of 0.001. The Standard Model with pure V-A interaction gives 0.75 for this parameter. The world average value is 0.7518 +/- 0.0026. A deviation of the value of Rho from 0.75 will …

Regulation of p190RhoGEF by Activated Rho and Rac GTPases: Amplification and Crosstalk
The Rho family of monomeric GTPases regulates a wide range of cellular processes including cytoskeletal structure, motility, cell division, gene transcription, vesicular transport, and various enzymatic activities. Activation of Rho proteins largely depends on Rho Guanine nucleotide Exchange …
