We used unit root and cointegration techniques to determine the long run relationship between GDP and investment for 90 countries using data from World Bank for the period 1960-1992. In the first step of our analysis we found GDP and investment integrated of different orders for 33 countries. Second step of our analysis shows no cointegration between GDP and investment for 25 countries and coin...

L-Fucose is a monosaccharide found as a component of glycoproteins and cell wall polysaccharides in higher plants. The MUR1 gene of Arabidopsis thaliana encodes a GDP-D-mannose 4,6-dehydratase catalyzing the first step in the de novo synthesis of GDP-L-fucose from GDP-D-mannose (Bonin et al. 1997, Proc. Natl Acad. Sci. USA, 94, 2085-2090). Plant genes encoding the subsequent steps in L-fucose s...

Strain GS, a gram-negative motile bacterium isolated from soil, synthesizes two polysaccharides. The synthesis of a uranic acid-containing polysaccharide is derepressed by high concentrations of Na2SOd, while the synthesis of the polysaccharide containing equal quantities of n-rhamnose and n-talomethylose is repressed by NazS01 (1, 2). L-F’ucose and L-rhamnose are the methylpentoses commonly fo...

We compared the effects of oral administration of high-dose or low-dose glutamine dipeptide (GDP), alanine (ALA), glutamine (GLN), and ALA + GLN on the blood availability of amino acids in rats submitted to insulin-induced hypoglycemia (IIH). Insulin detemir (1 U/kg) was intraperitoneally injected to produce IIH; this was followed by oral administration of GDP, GLN + ALA, GLN, or ALA. We observ...

The effects of the adenylate cyclase inhibitor GDP beta S on the response of Aplysia neuron R15 to serotonin (5HT) were investigated. Previous studies have demonstrated that 5HT causes an increase in K+ conductance in R15 and that the response is mediated by cAMP. At concentrations in the micromolar range, GDP beta S inhibits the stimulation of adenylate cyclase by 5HT in particulate fractions ...

Real GDP and oil prices are decomposed into common stochastic trend and cycle processes, using structural time series models. Potential real GDP is represented by the level of the trend component of real GDP. The potential rate of growth of real GDP is represented by the stochastic drift element of the trend component. We find that there is a strong association at the trend and cycle frequencie...

ATP and UTP support microtubule assembly through the action of brain nucleoside-5'-diphosphate kinase on GDP. Penningroth and Kirschner (1977) J. Mol. Biol. 115, 643-673) have proposed that microtubule assembly may occur by either of two mechanisms: indirectly, through nucleoside-5'-diphosphate kinase-catalyzed phosphorylation of uncomplexed GDP and directly by nucleoside-5'-diphosphate kinase-...

The effects of ribosomes and Mg-2plus on the binding of GDP and GTP to elongation factor 2 (EF-2) have been studied by an improved filter-binding assay. Both ribosomes and Mg-2plus strongly inhibit the binding of GDP but have apparently no effect on the GTP binding to the enzyme. An apparent stimulation by ribosomes of GTP binding to EF-2 is time-dependent and parallels a concomitant increase o...
