Dopamine-induced synaptic plasticity in the amygdala in saline-and cocaine-treated animals undergoing conditioned place preference
… demonstrated a link between phospholipase D (PLD) and metabotropic glutamate receptors (mGluRs), while other studies show an interaction between dopamine receptors (DRs) and PLD. Therefore, we investigated the mechanisms of the dopamine agonist-induced synaptic plasticity that is enhanced in …

Attenuation of Corynebacterium pseudotuberculosis by targeted mutagenesis of the phospholipase D gene.
A toxic phospholipase D (PLD), is thought to be an essential virulence determinant of Corynebacterium pseudotuberculosis, an animal pathogen which causes chronic, suppurative infections. In this study, PLD was purified from C. pseudotuberculosis biovar equi isolate 155 and the gene encoding PLD …

Molecular and biochemical characterization of phospholipase D in cotton (Gossypium hirsutum L) seedlings.
… (NAPE) via the action of phospholipase D (PLD). In an effort to identify a functional NAPE-PLD in cotton seeds and seedlings, we have screened a cotton seedling cDNA (cotyledon mRNA from 48 h dark grown seedlings) library with a 1.2 kb tobacco partial cDNA fragment encoding the middle third …

Development and physiological characteristics of avian fast and slow contracting muscles
1. The ALD and PLD muscles from the chicken.were studied throughout ex ovo development from 3 days of age until early adulthood. These two muscles provided a model for studying phasic fast fibres and tonic slow fibres. 2. Development over the first 30 days was compared in control groups and groups …

Tobacco Phospholipase D β1: Molecular Cloning and Biochemical Characterization
… plants were developed containing a partial PLD clone in antisense orientation. The PLD isoform targeted by the insertion was identified. A PLD clone was isolated from a cDNA library using the partial PLD as a probe: Nt10B1 shares 92% identity with PLDβ1 from tomato but lacks the C2 domain. …

Phospholipase D Signaling in T Cells
… induces the activation of phospholipase D (PLD) signaling. Phospholipase D (PLD) is a phosphodiesterase that catalyzes the conversion of phosphatidyl choline (PC) to phosphatidic acid (PA). PA is an important lipid second messenger and is known to mediate a variety of cellular functions. …

Concentration and distribution of organic phosphorus through a grassland catchment transfer continuum
… (DNA-P) and phospholipid-phosphorus (PLD-P) from soil in a grassland catchment. DNA-P and PLD-P are among the most labile and biodegradable (and hence interesting) of organic phosphorus compounds. This study was conducted to assess the flow of these compounds along the continuum from …

DEVELOPMENT AND APPLICATION OF CHEMOENZYMATIC TOOLS TO VISUALIZE MAMMALIAN PHOSPHOLIPASE D SIGNALING
… signal transduction pathways. Phospholipase D (PLD) enzymes are a critical signaling node responsible for production of the pleiotropic lipid second messenger phosphatidic acid via hydrolysis of phosphatidylcholine. It remains a mystery how this one lipid signal can cause such diverse …

Beteiligung der Phospholipase D an der Regulation der Synthese von Phosphatidylinositol-4,5-bisphosphat durch Arf- und Rho-GTPasen
The reaction product of phospholipase D (PLD), phosphatidic acid (PA), was found to stimulate phosphatidylinositol-4-phosphate-5-kinase (PIP-5-kinase) activity in vitro. In the present study, we have examined wether PLD affects the synthesis of phosphatidylinositol 4,5-bisphosphate (PIP2) by …

Femtosecond pulsed laser deposition
… of the conventional pulsed laser deposition (PLD) technique. The first technique is femtosecond PLD, whereby the laser used to ablate the target has a significantly higher peak intensity and shorter pulse duration as compared to conventional nanosecond lasers more commonly used for PLD. …

Investigating the Effects of Particle Loading and Agglomeration on Respirable Coal Mine Dust Particle Classification by SEM-EDX
… interferences due to particle loading density (PLD) and agglomeration. PLD refers to the number of particles per unit area of substrate, while agglomeration describes clustered or overlapping particles. This thesis includes two studies aimed at exploring the effects of both PLD and agglomeration …

On the growth and characterisation of Zinc Oxide
… structural properties of ZnO grown via grown via PLD and VPT were examined. Both growth techniques were successful in producing nanostructured ZnO with thin films also produced with PLD. An epitaxial relationship to the substrate was found for all materials. A temperature-stepping growth process …
