For 35 years, some researchers have argued that CNV resolution may affect or even produce the increased P3 for NoGo compared to Go trials, and thus that no 'inhibitory' NoGo P3 exists. This is based on the work of Simson et al. (1977b), the scalp topography of potentials in auditory and visual Go/NoGo tasks. Electroencephalography and Clinical Neurophysiology, 43, 864-875, which compared Go and...

P3 is a murine IgM mAb that recognize N-glycosylated gangliosides, sulfatides, and antigens expressed in melanoma, breast, and lung human tumors. This antibody has the ability to trigger an IgG antibody response in the syngeneic BALB/c model, even when it is administered in the absence of adjuvant or carrier protein. The mechanism by which the P3 mAb, a self-immunoglobulin, induce this immune r...

The cauliflower mosaic virus (CaMV) has an icosahedral capsid composed of the viral protein P4. The viral product P3 is a multifunctional protein closely associated with the virus particle within host cells. The best-characterized function of P3 is its implication in CaMV plant-to-plant transmission by aphid vectors, involving a P3-virion complex. In this transmission process, the viral protein...

The role of Ins(1,4,5)P3 in receptor-induced Ca2+ mobilization in pituitary cells was studied at the single-cell level. Experimental strategies were developed which allowed a comparative analysis of the effects of Ins(1,4,5)P3 with those of receptor activation under identical conditions. These include microfluorimetry as well as a novel technique which permits the controlled and rapid applicati...

Serum from patients who have suffered acute pancreatitis contains P3, an isoenzyme of pancreatic-derived amylase (EC 3.2.1.1). Heretofore, complete resolution of P3 from the major salivary isoenZyme in serum, Si, has not been possible, thus compromising the diagnostic potential of P3 for pancreatitis. I describe an electrophoretic method for the essentially complete resolution of P3 from S1 by ...

An antimicrobial substance produced by Streptomyces sp. No. 87 was partially purified and studied for its antibacterial characteristics using the swab paper disc technique. The cell-free culture filtrate showed antibacterial activity against several species of pathogens including Gram-positive bacteria, i.e. Bacillus cereus ATCC 11778, B. subtilis TISTR 008, B. megaterium, Staphylococcus aureus...

We studied the effects of age on the limbic and scalp P3 in 45 patients with intracranial electrodes implanted for pre-surgical investigation of focal seizures. Scalp P3 data from a reference group of 24 healthy control subjects were also analyzed for comparison. An auditory oddball paradigm with infrequent stimuli being presented with a probability of 0.20 was used. In normals P3 latency incre...

The present review focuses on the utility of the amplitude of P3 of as a measure of processing capacity and mental workload. The paper starts with a brief outline of the conceptual framework underlying the relationship between P3 amplitude and task demands, and the cognitive task manipulations that determine demands on capacity. P3 amplitude results are then discussed on the basis of an extensi...

DNA encoding the coat protein (P3) of a Scottish isolate of potato leafroll virus (PLRV) was inserted into the genome of Autographa californica nucleopolyhedrovirus (AcNPV) such that the coat protein was expressed either in an unmodified form or with the addition of the amino acid sequence MHHHHHHGDDDDKDAMG at the N terminus (P3-6H). Insect cells infected with these recombinant baculoviruses ac...
