Phosphatidylcholine-specific phospholipase C (PC-PLC) is a necessary intermediate in transducing apoptotic signals for tumor necrosis factor and Fas/Apo-1 ligands in nonneuronal cells. The data presented here show that PC-PLC also is required in oxidative glutamate-induced programmed cell death of both immature cortical neurons and a hippocampal nerve cell line, HT22. In oxidative glutamate tox...

In recent history there has been an enormous development in the subject area of Power Line Communications (PLC), since it has become possible due to advanced digital communications and digital signal processing techniques to use power lines for data transmission. PLC allows the use of the dynamic and far-reaching power cables to support high speed communication capabilities. Discrete Multi-tone...

The phosphatidylinositol (PI)-specific phospholipase C (PLC) activity contained in sonicates of casein-elicited (4-6 hr) rat neutrophils has been identified and characterized. With phosphatidylinositol (PI) as the substrate, PLC activity is found both in the supernate and pellet of a 100,000g spin of the neutrophil sonicate. Further fractionation of the crude sonicate by centrifugation on disco...

This paper presents a design and implementation of a monitoring and control system for the three-phase induction motor based on programmable logic controller (PLC) technology. Also, the implementation of the hardware and software for speed control and protection with the results obtained from tests on induction motor performance is provided. The PLC correlates the operational parameters to the ...

Prof.T.Velnampy Dean, Faculty of Management Studies and Commerce, University of Jaffna. Abstract This study examines the performance of Dialog Axiata PLC and Sri Lanka Telecom PLC by employing both cash flow ratios and traditional financial ratios over the past five years. Using the financial statements from Colombo Stock Exchange (CSE) website, independent sample t-tests were used for the anal...

Maintenance of the epithelial barrier in the intestinal tract is necessary to protect the host from the hostile luminal environment. Phospholipase C-β (PLC-β) has been implicated to control myriad signaling cascades. However, the biological effects of selective PLC-β isozymes are poorly understood. We describe novel findings that lysophosphatidic acid (LPA) regulates PLC-β1 and PLC-β2 via two d...

Phospholipase C (PLC) is a ubiquitous enzyme involved in the regulation of a variety of cellular processes. Its dependence on Ca is well recognized, but it is not known how PLC activity is affected by physiological variations of the cytoplasmic Ca concentration ([Ca ]i). Here, we applied evanescent wave microscopy to monitor PLC activity in parallel with [Ca ]i in individual insulin-secreting I...

Constitutive activation of the transcription factor Stat5 in hematopoietic stem/progenitor cells leads to various hematopoietic malignancies including myeloproliferative neoplasm (MPN). Our recent study found that phospholipase C (PLC)-β3 is a novel tumor suppressor involved in MPN, lymphoma and other tumors. Stat5 activity is negatively regulated by the SH2 domain-containing protein phosphatas...

Among the Rosaceae species, the gametophytic self-incompatibility (GSI) is controlled by a single multi-allelic S locus, which is composed of the pistil-S and pollen-S genes. The pistil-S gene encodes a polymorphic ribonuclease (S-RNase), which is essential for identifying self-pollen. However, the S-RNase system has not been fully characterized. In this study, the self-S-RNase inhibited the Ca...
