The ability of an AEF (axolemma-enriched fraction) to influence the proliferation, survival and differentiation of OPC (oligodendrocyte progenitor cells) was evaluated. Following addition of AEF to cultured OPC, the AEF associated with the outer surface of OPC so that subsequent metabolic events were likely mediated by direct AEF-OPC contact. Addition of AEF to the cultured OPC resulted in a do...

BACKGROUND Historically, oropharyngeal cancer (OPC) has been attributed to risk factors such as smoking and alcohol use. The increased incidence of OPC has been driven by human papillomavirus (HPV) infection. METHODS A search of the literature involving HPV infection and OPC was performed, along with a search of ongoing clinical trials regarding HPV-positive OPC. RESULTS This review summari...

We previously found mild hypothermia (34-36 degrees C), induced before cardiac arrest, to improve neurologic outcome. In this study we used a reproducible dog model to evaluate mild hypothermia by head cooling during arrest, continued with systemic cooling (34 degrees C) during recirculation and for 1 h after arrest. In four groups of dogs, ventricular fibrillation (no flow) of 12.5 min at 37.5...

Variational Lithography Modeling and Model Calibration∗ Peng Yu, Sean X. Shi, and David Z. Pan Department of Electrical and Computer Engineering The University of Texas, Austin, TX 78712 Abstract Optical proximity correction (OPC) is one of the most widely used Resolution Enhancement Techniques (RET) in nanometer designs to improve subwavelength printability. Conventional model-based OPC assume...

In this article, the current technological state of OPC (Openness, Productivity, and Collaboration; formerly “OLE for Process Control”) standards and the problem statement of these OPC standards are discussed. The development of an OPC clientserver framework for monitoring and control systems is introduced by using the new OPC Unified Architecture (UA) specifications, Service Oriented Architect...

BACKGROUND Promotion of remyelination is a major goal in treating demyelinating diseases such as multiple sclerosis (MS). The recombinant human monoclonal IgM, rHIgM22, targets myelin and oligodendrocytes (OLs) and promotes remyelination in animal models of MS. It is unclear whether rHIgM22-mediated stimulation of lesion repair is due to promotion of oligodendrocyte progenitor cell (OPC) prolif...

Oropharyngeal cancer (OPC) is more frequent in men than women mainly due to the heavier and longer duration of smoking in men. Human papillomavirus (HPV) has a role in the rising incidence of OPC in the United States and other high-income countries. To determine whether there is a difference in the proportion of HPV-attributable OPC between men and women, we systematically retrieved HPV prevale...

This is the second of our three-part series on oral and pharyngeal cancer (OPC) in Florida.1 Research for this second report was driven by our desire to broaden our understanding of trends in OPC incidence. Our previous publications provided evidence that the public knows little about OPC. Moreover, the actions taken by most members of the public are based on the notion that if OPC were importa...

cAMP plays a major role in cystogenesis. Recent in vitro studies suggested that cAMP stimulates B-Raf/ERK activation and proliferation of cyst-derived cells in a Ca(2+) inhibitable, Ras-dependent manner. OPC-31260, a vasopressin V2 receptor (VPV2) antagonist, was shown to lower renal cAMP and inhibit renal disease development and progression in models orthologous to human cystic diseases. Here ...

Purpose – The purpose of this paper is to focus on the effects of the ethical climate in Chinese certified public accounting (CPA) firms on auditors’ perceptions of organizational-professional conflict (OPC) and affective organizational commitment (OC). We also test for differences in the perceived ethical climates of local and international CPA firms. Design/methodology/approach – The study is...
