A study of oropharyngeal candidiasis (OPC) in Indian human immunodeficiency virus (HIV)/AIDS patients was conducted over a period of 15 months. This study revealed that 75% of the HIV/AIDS patients had OPC. MIC testing revealed that 5% of the Candida isolates were fluconazole resistant. A correlation between CD4(+)-T-cell counts and development of OPC in HIV/AIDS patients was also observed. Mol...

In demyelinating diseases such as multiple sclerosis, one of the treatment strategies includes remyelination using oligodendrocyte precursor cells (OPC). Catalpol, the extract of radix rehmanniae, is neuroprotective. Using an OPC culture model, we showed that 10 μM catalpol promotes OPC proliferation, cell migration and differentiation into mature oligodendrocytes. The 10 μM catalpol displayed ...

Acute manifestations of Organophosphate Compound (OPC) poison are due to effect cholinergic excess. Others are intermediate syndrome [IMS], organophosphate induced delayed neuropathy [OPIND] and chronic organophosphate induced neuropsychiatric disorder [COPIND]. All these manifestation have specific period of occurrence and duration. There are very sparse reports of toxic demylination due to OP...

In vascular smooth muscle cells arginine vasopressin acting through the V, receptor increases intracellular Ca, leading to vasoconstriction. Recent studies have also shown that vasopressin activates mitogen-activated protein kinase (MAP kinase), which may contribute to vasopressin-induced hypertrophy of vascular smooth muscle cells. We examined the ability of an orally active, nonpeptide select...

We demonstrate fiber nonlinearity mitigation by using multiple optical phase conjugations (OPCs) in the WDM transmission systems of both 8 × 32-Gbaud PDM QPSK channels and 8 × 32-Gbaud PDM 16-QAM channels, showing improved performance over a single mid-span OPC and no OPC in terms of nonlinear threshold and a best achievable Q2 factor after transmission. In addition, after an even nu...

To study the role of vasopressin (VP) in essential hypertension, we examined plasma levels of VP and blood pressure (BP) response to an orally active V1 receptor antagonist, OPC-21268, in hypertensive patients on diets with different sodium contents. Plasma VP was determined in 12 normotensive subjects and 12 patients with mild essential hypertension on a regular sodium diet, and in eight hyper...

During embedded software development of complex control system, the calibration is an important approach to obtain optimal parameters of embedded software. Currently, typical calibration systems are with poor adaptability for various controllers which have different communication interfaces and calibration protocols. In order to solve the problem, an improved architecture for embedded controlle...

Neisseria meningitidis Opc protein is an effective invasin for human endothelial cells. We have investigated novel human endothelial receptors targeted by Opc and observed that Opc-expressing bacteria interacted with a 100 kDa protein in whole-cell lysates of human endothelial and epithelial cells. The identity of the protein was established as alpha-actinin by mass spectrometry. Opc expression...

To elucidate the effect of the arginine vasopressin (AVP) system in vivo, especially V1 and V2 activity, on blood pressure, we measured the acute changes in blood pressure and heart rate after AVP, OPC-21,268 (a V1 receptor antagonist), and OPC-31,260 (a V2 receptor antagonist) were injected intravenously in anesthetized spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats at the a...
