Gross domestic product (GDP) and gross domestic income (GDI) are in theory estimates of the same concept, namely economic production over a defined span of time and space. Yet the two measures are compiled using different source data, and the two measures often give different indications of the direction of the economy. This raises the issue of which of the two measures is a more accurate estim...

Mammalian neuroglobin (Ngb) protects neuronal cells under conditions of oxidative stress. We previously showed that human Ngb acts as a guanine nucleotide dissociation inhibitor (GDI) for the α-subunits of heterotrimeric Gi/o proteins and inhibits reductions in cAMP concentration, leading to protection against cell death. In the present study, we created human E60Q Ngb mutant and clarified that...

Das (Geo-) Datenmanagement hat für Projekte des nachhaltigen Landmanagements einen besonderen Stellenwert aufgrund der immanenten Interdisziplinarität. Da viele verschiedene Projektpartner auf einen Austausch von Daten angewiesen sind, sollten standardkonforme, webbasierte Geodateninfrastrukturen (GDI) zum Einsatz kommen. Im Beitrag wird die Software GeoNetwork OpenSource zur Errichtung einer G...

Intracellular vesicular trafficking is regulated by approximately 60 members of the Rab subfamily of small Ras-like GDP/GTP binding proteins. Rab proteins cycle between inactive and active states as well as between cytosolic and membrane bound forms. Membrane extraction/delivery and cytosolic distribution of Rabs is mediated by interaction with the protein GDP dissociation inhibitor (GDI) that ...

A novel regulatory protein for the rho proteins (rhoA p2 1 and rhoB p20), belonging to a ras p2 llras p21like small molecular weight (M,) GTP-binding protein (G protein) superfamily, was purified to near homogeneity from bovine brain cytosol and characterized. This regulatory protein, designated here as GDP dissociation inhibitor (GDI) for the rho proteins (rho GDI), inhibited the dissociation ...

VLSI technology has developed over the years thereby enhancing the performance of chips in terms of three basic constraints viz. delay, power and area. Gate Diffusion Input technique is one such method which attempts to minimize the delay and power consumed by the circuit. The paper basically focuses on the implementation of the technique on combinational logic circuits and experimental delay r...

rho GDP dissociation inhibitor (GDI) is an inhibitory GDP/GTP exchange protein for a group of small GTP-binding proteins including at least rhoA p21, rhoB p21, rac1 p21, rac2 p21, and G25K. Microinjection of rho GDI into Swiss 3T3 cells made the cells round and refractile. This morphological change was accompanied by the disappearance of stress fibers. The rho GDI action was prevented by comicr...

Three-dimensional gait analysis (3DGA) is an important element in the quantitative evaluation of gait in subjects with Parkinson's disease (PD). Indexes, such as the Gait Deviation Index (GDI), have recently been proposed as a summary measure of gait. The aim of the present study was to investigate the effectiveness of the GDI and spatiotemporal variables in the quantification of changes in gai...

BACKGROUND Small GTPases of the Rab family can cycle between a GTP- and a GDP-bound state and also between membrane and cytosol. The latter cycle is mediated by the Guanine Nucleotide Dissociation Inhibitor GDI, which can selectively extract GDP-bound Rab proteins from donor membranes, and then reload them on target membranes. In previous studies, we found that capture of the small GTPase Rab5,...

Bacterial pathogens deliver effector proteins with diverse biochemical activities into host cells, thereby modulating various host functions. Legionella pneumophila hijacks host vesicle trafficking to avoid phagosome-lysosome fusion, a mechanism that is dependent on the Legionella Dot/Icm type IV secretion system. SidM/DrrA, a Legionella type IV effector, is important for the interactions of Le...
