INTRODUCTION Oropharyngeal candidiasis (OPC) is the most common opportunistic fungal infection reported in human immunodeficiency virus (HIV) positive patients worldwide. This prospective study was undertaken to investigate OPC and Candida colonization (CC) and their correlation with CD4+ cell counts and antiretroviral therapy (ART) in HIV-positive patients. METHODOLOGY In total, 190 HIV-posi...

The host vasculature is believed to constitute the principal route of dissemination of Neisseria meningitidis (Nm) throughout the body, resulting in septicaemia and meningitis in susceptible humans. In vitro, the Nm outer membrane protein Opc can enhance cellular entry and exit, utilising serum factors to anchor to endothelial integrins; but the mechanisms of binding to serum factors are poorly...

Current adjuvant treatment guidelines for oropharyngeal squamous cell carcinoma treated with primary surgery are based on studies that predate the human papillomavirus (HPV) era. HPV-associated oropharynx carcinoma (HPV-OPC) has a much more favorable prognosis compared to HPV-unassociated cancer and is increasingly considered to be a distinct disease entity due to its unique etiology, presentat...

We describe a new approach to the fabrication of surface-enhanced Raman scattering (SERS) substrates using gold nanorod (GNR) nanopowders to prepare concentrated GNR sols, followed by their deposition on an opal-like photonic crystal (OPC) film formed on a silicon wafer. For comparative experiments, we also prepared GNR assemblies on plain silicon wafers. GNR-OPC substrates combine the increase...

Oropharyngeal candidiasis (OPC) is the most frequent opportunistic infection associated with HIV infection. Therapies such as topical clotrimazole and nystatin, as well as oral azoles, which had previously been effective prior to the advent of HIV, are increasingly only partially effective in OPC in HIV infection. The effectiveness of oral amphotericin B suspension for OPC is described in 17 HI...

In the deep submicron manufacturing (DSM) era, lithography/yield and noise are critical issues to be considered. Optical Proximity Correction (OPC) is becoming a key compensate technique for the light diffraction effect in lithography. Both OPC effect and the capacitive crosstalk on some wire segments can only be analyzed post routing in late design stage or post-silicon stepping design change....

This paper presents the findings of a study on solidification/stabilization (S/S) of lead-contaminated soil using ordinary Portland cement (OPC) and rice husk ash (RHA). The effects of varying lead concentrations (in the form of nitrates) in soil samples on the physical properties of their stabilized forms, namely unconfined compressive strength (UCS), setting times of early mixtures and change...

Light scattering in biological tissue significantly limits the accessible depth for localized optical interrogation and deep-tissue optical imaging. This challenge can be overcome by exploiting the time-reversal property of optical phase conjugation (OPC) to reverse multiple scattering events or suppress turbidity. However, in living tissue, scatterers are highly movable and the movement can di...

It is a well known fact that laboratory work has big importance to prepare automation students for difficulties of industrial world. With this purpose, in this study, local control of OPC (OLE for Process Control) based SCADA (Supervisory Control And Data Acquisition) system of which prototype constructed in laboratory environment is realized for educational purposes using Siemens CPU 224. The ...

UA Model Specification Services are independent of the model ➞ At the lowest level are the abstract OPC-UA model and the services, including the whole address space model, different object and variable structures, alarms and more. ➞ The next level (Services Binding) is used to specify how the services are to be mapped to certain protocols. Currently mappings for TCP (UATCP) and for HTTP (OPC-UA...
