Recently, dynamic nuclear polarization enhanced nuclear magnetic resonance (DNP/NMR) has emerged as a powerful technique to obtain significant enhancements in spin spectra from biological samples. For DNP in modern NMR systems, a high power continuous-wave source in the submillimeter wavelength range is necessary. Gyrotrons can deliver tens of watts of CW power at submillimeter wavelengths and ...

Prolonged interference or suppression of maternal antibodies of the humoral immune response of newly hatched chicks to active immunization has been documented; however, the immunological mechanisms responsible for such suppression are still unclear. Laying hens were immunized with dinitrophenyl-keyhole limpet hemocyanin (DNP-KLH). Purified maternal anti-DNP or non-specific IgY antibodies were t...

Since the introduction 10 years ago of the dissolution method, Dynamic Nuclear Polarization (DNP) became a widely applied and powerful technique to enhance nuclear magnetic resonance (NMR) signals of low naturally abundant, insensitive nuclear spins for analytical chemistry and biomedical research. The aim of DNP is to obtain a very high degree of polarization on the nuclei of interest in cryog...

There is little research among doctor of nursing practice (DNP) students, a fast-growing population of nurses engaged in doctoral study. In this descriptive correlational study, levels of perceived stress, sense of belonging, and the relationship between these variables were examined. The sample included 89 female, predominantly White, post-master's DNP students from a Midwest university. A sta...

A higher percentage of specific antigen-binding cells can be detected not only in normal CBA/J mouse spleen cell preparations (0.99%), but also in the normal thymus cell preparations (0.15%) with the use of [(125)I]2,4-dinitrophenyl-human IgG (DNP-HGG) as compared with most other antigens employed under similar conditions. The receptors on these cells are mainly specific for the DNP group as sh...

The past several years have seen explosive growth in the number of doctor of nursing practice (DNP) degree programs offered by colleges of nursing in the United States. Through a process of trial and error since 2005, the faculty at the University of Colorado, College of Nursing, have revised the course structure and procedures related to the DNP capstone project to improve the quality and usef...

Despite common comorbidity of sexual and urinary dysfunctions, the interrelationships between the neural control of these functions are poorly understood. The medullary reticular formation (MRF) contributes to both mating/arousal functions and micturition, making it a good site to test circuitry interactions. Urethane-anesthetized adult Wistar rats were used to examine the impact of electricall...

Diabetic neuropathic pain (DNP), one of the early symptoms of diabetic neuropathy, relates to metabolic disorders induced by high blood glucose, neurotrophic vascular ischemia and hypoxia, and autoimmune factors. This study was aimed at exploring the effects of long noncoding RNA (lncRNA) BC168687 siRNA on DNP mediated by P2X7 receptor on SGCs in DRG of rats. The mechanical withdrawal threshold...

RATIONALE Myeloid cell content in atherosclerotic plaques associates with rupture and thrombosis. Thus, imaging of lesional monocytes and macrophages could serve as a biomarker of disease progression and therapeutic intervention. OBJECTIVE To noninvasively assess plaque inflammation with dextran nanoparticle (DNP)-facilitated hybrid positron emission tomography/magnetic resonance imaging (PET...

To better understand proteasomal degradation of nuclear proteins and viral antigens we studied mutated forms of influenza virus nucleoprotein (NP) that misfold and are rapidly degraded by proteasomes. In the presence of proteasome inhibitors, mutated NP (dNP) accumulates in highly insoluble ubiquitinated and nonubiquitinated species in nuclear substructures known as promyelocytic leukemia oncog...
