Triphasic waves are seen in the electro-encephalogram of adult patients with toxic-metabolic encephalopathies of various origins. Levetiracetam is a broad spectrum anti-epileptic drug with renal elimination and no hepatic metabolism. We describe the case of encephalopathy with triphasic waves concomitant with levetiracetam accumulation in a patient with chronic renal failure. The condition was ...

We have examined the pre-steady state reduction kinetics of the Saccharomyces cerevisiae cytochrome bc(1) complex by menaquinol in the presence and absence of endogenous ubiquinone to elucidate the mechanism of triphasic cytochrome b reduction. With cytochrome bc(1) complex from wild type yeast, cytochrome b reduction was triphasic, consisting of a rapid partial reduction phase, an apparent par...

Objective: To evaluate the diagnostic value of triphasic spiral Computerized Tomography (CT) Hounsfield (HU) and pattern in differentiating focal liver lesions. Methods: The study was conducted in Department of Radiology:1) Fedail Hospital, 2)Alfaisal Hospital,3) Alzitona Hospital,3) Alturky Center.The study was obtained during the period spanned from January 2015up to August 2016.By convenient...

Biphasic defibrillation waveforms are now accepted as being more effective at terminating ventricular fibrillation (VF) than monophasic waveforms. If two phases are better than one, this naturally leads to the hypothesis that additional phases improve efficacy. This study tests the hypothesis by adding one additional phase. We examined the efficacy of 18 different triphasic waveforms simultaneo...

Creutzfeldt disease and of hepatic coma is probably also due to a compensating action in the presence of a disordered dopaminergic system. Taken together, these findings suggest that triphasic waves occurring repetitively and regularly in an E.E.G. are caused by a disturbance of the dopaminergic system. The question arises whether the hyperkinesia and the coma are caused by disorders of two sep...

Biphasic, triphasic and multiphasic (polyphasic) calcium orthophosphates have been sought as biomaterials for reconstruction of bone defects in maxillofacial, dental and orthopedic applications. In general, this concept is determined by advantageous balances of more stable (frequently hydroxyapatite) and more resorbable (typically tricalcium orthophosphates) phases of calcium orthophosphates, w...

Strains of most Salmonella serovars produce either one (monophasic) or two (diphasic) antigenic forms of flagellin protein, but strains capable of expressing three or more serologically distinct flagellins ("complex" serovars) have occasionally been reported. A molecular genetic analysis of a triphasic strain of the normally diphasic serovar Salmonella rubislaw revealed that it has three flagel...

*Lu, XL; *Guo, XE; +*Mow, VC +*Department of Biomedical Engineering, Columbia University, New York, NY [email protected] INTRODUCTION The triphasic mixture theories for articular cartilage [1] have been successfully used to describe the flow-dependent and flow-independent viscoelastic behaviors, swelling behaviors, and electrokinetic behaviors of charged-hydrated soft tissues in the last two d...
