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...
در این پروژه تحقیقاتی، نخست با استفاده از مدل کار ویژه برناکی، با انتخاب مقادیر مختلف برای سرعت دورانی و پیش روی و در نظر گرفتن خاک با بافت و رطوبت متوسط مقادیر عددی کار ویژه به دست آمد. سپس با تعیین ورود و خروج تیغه توسط اندازه گیری ارتفاع شیارهای کف شخم و قرار دادن آن ها در فرمول طول مسیر برش گرینشاک و متیاشین، طول مسیر برش به دست آمد، آن گاه با قرار دادن آن در فرمول سردیشنی و گرینشاک و مقایس...
The immunodominant antimitochondrial antibody response in patients with primary biliary cirrhosis (PBC) is directed against the E2 component of the pyruvate dehydrogenase complex (PDC-E2). Based on our earlier observations regarding peripheral blood mononuclear cell (PBMC) T cell epitopes, we reasoned that a comparative analysis of the precursor frequencies of PDC-E2 163-176-specific T cells is...
Pyruvate decarboxylase (PDC), an enzyme central to homoethanol fermentation, catalyses the non-oxidative decarboxylation of pyruvate to acetaldehyde with release of carbon dioxide. PDC enzymes from diverse organisms have different kinetic properties, thermal stability and codon usage that are likely to offer unique advantages for the development of desirable Gram-positive biocatalysts for use i...
Plasmacytoid dendritic cells (pDC) are the major producers of type I interferons (IFNs) in humans and rapidly produce IFN-α in response to virus exposure. Although HIV infection is associated with pDC activation, it is unclear why the innate immune response is unable to effectively control viral replication. We systematically compared the effect of HIV, Influenza, Sendai, and HSV-2 at similar t...
