Human plasmacytoid dendritic cells (PDC) are a major source of IFN-alpha upon exposure to enveloped viruses and TLR-7 and TLR-9 ligands. Although IFN regulatory factor-7 (IRF-7) is known to play an essential role in virus-activated transcription of IFN-alpha genes, the molecular mechanisms of IFN-alpha production in human PDC remain poorly understood. We and others have recently reported high c...

PDC (Plant Density of Cotton) was an essential parameter for estimating the cotton yield and developing the zone-management measurements. This paper proposed a new method to retrieve PDC from the satellite remote sensing data. The thirteen fields of Xinjiang Production and Construction Corps (XPCC) (total 630 hm) were selected as the study area, where the sowing date, emergence date, and PDC we...

UNLABELLED Pyruvate dehydrogenase (PDH) complex (PDC) deficiency is an inborn error of pyruvate metabolism causing a variety of neurologic manifestations. Systematic analyses of development of affected brain structures and the cellular processes responsible for their impairment have not been performed due to the lack of an animal model for PDC deficiency. METHODS In the present study we inves...

The objective of this study was to investigate the effects of L-glutamate (Glu) deficiency or L-trans pyrrolidine-2,4-dicarboxylic acid (PDC) supplementation on the proliferation of pig intestinal epithelial cells (IPEC-1). First, IPEC-1 cells were cultured in normal growing medium supplemented with 0 (Control), 50, 100, or 200 µmol/L PDC to determine an appropriate concentration of PDC supplem...

Elevated levels of plasmacytoid dendritic cells (pDC) have been observed as breast cancer disseminates to the bone. The selective depletion of pDC in mice led to a total abrogation of bone metastasis as well as to an increase in TH1 antitumor response, suggesting that pDC may be considered as a potential therapeutic target for metastatic breast cancer.

The pyruvate dehydrogenase enzyme complex (PDC) is rate limiting for glucose oxidation in the heart. Inhibition of PDC by end-product feedback and phosphorylation by pyruvate dehydrogenase kinase (PDK) operate in concert to inhibit PDC activity. Because the transcriptional regulator peroxisome proliferator-activated receptor (PPAR)-alpha increases PDK expression in some tissues, we examined wha...

PURPOSE The purpose of the study was to empirically test items of a new measure designed to assess person-directed care (PDC) practices in long-term care. DESIGN AND METHODS After reviewing the literature, we identified five areas related to PDC: personhood, comfort care, autonomy, knowing the person, and support for relationships. We also identified an additional component of environmental s...

This chapter provides a framework for introducing parallel and distributed computing (PDC) concepts as they arise naturally in digital logic. It is directed primarily towards the instructor of a first digital logic course, although a motivated student may find it useful as well. Because a digital logic course lays the foundation for other courses such as computer organization and architecture, ...

High-gain parametric down-conversion (PDC) is a source of bright squeezed vacuum, which is a macroscopic nonclassical state of light and a promising candidate for quantum information applications. Here we study its properties, such as the intensity spectral width and the spectral width of pairwise correlations. In agreement with the theory, we observe an increase in the spectral width by 27% co...

A significant lag phase was observed in the accumulation of product for the reaction catalyzed by pyruvate decarboxylase (PDC) purified from mature maize kernels. The effects of pH, pyruvate, potassium chloride, PDC concentration, and Mg(2+)-thiamine pyrophosphate upon this lag and upon the observed cooperativity were investigated. PDC preincubated with Mg(2+)-thiamine pyrophosphate for six day...
