Article abstract—Neuron-specific enolase (NSE) is a sensitive marker of brain injury after stroke, global ischemia, and coma. We report changes in serum NSE (s-NSE) 19 patients who sustained status epilepticus. s-NSE peaked within 24 to 48 hours The mean peak level for the entire group was elevated compared with levels normal controls (24.87 ng/ml versus 5.36 ng/ml, <i>p</i> = 0.0001) epileptic 4.61 0.0001). 11 subjects without an acute neurologic insult (15.44 ng/ml) also significantly...

Neuron-specific enolase (NSE) is a sensitive marker of brain damage in stroke, global ischemia, and coma. Serum NSE also correlated with the duration outcome status epilepticus (SE). CSF-NSE levels have not been previously reported SE. We report CSF concentrations 11 patients cryptogenic/remote symptomatic obtained within 24 hours SE showed increased 9 patients. The mean for group was elevated compared normal control subjects (30.8 ± 18.33 versus 10.76 3.08 ng/mL;<i>p</i> = 0.002). Further,...

The theory of the electron spin resonance dipolar coupled copper(II)–copper(II) pairs has been critically assessed and extended to take into account ΔM= 2 transitions that are observed experimentally. Computational procedures have evolved determine copper(II)–copper(III) separation in dimeric species. existence such species shown both aqueous non-aqueous solutions copper(II) chelates citric, malic, tartronic, mandelic, 5-sulphosalicyclic acids. computational applied calculating comparing...

Electron spin resonance measurements have been made on a number of copper (II) and vanadyl porphyrins. The spectra recorded at sample temperature 77°K low field components attributed to ΔM=2 transitions which provided evidence for the existence dimer species in solution. In one case, namely hematoporphyrin (IX) dimethylester, centered 950 G is thought be due ΔM=3 transition arising from trimer species. theory ESR dipolar coupled S=12 metal ions with particular reference systems involving...

Summary: Serum neuron‐specific enolase (s‐NSE), a marker of brain injury and acute seizures, was increased in 2 patients with nonconvulsive SE. (NCSE) accounting for s‐NSE changes. Increase provides further vivo evidence transient after NCSE.

The electronic and e.s.r. spectral data of the copper(II) cobalt(II) chelates tetra-2,3-pyridinoporphyrazine show that environment provided by ligand is similar to phthalocyanines. Potentiometric pH, spectrophotometric, measurements water soluble NN′N″N‴-tetramethyl quaternized tetracationic forms tetra-2,3-pyridinoporphyrazinates are free solute-solute interactions, stable in a wide range acidic solutions, but give rise some decomposition slightly alkaline solution. chelate five-...

Previous studies by a number of authors have shown that during B12-dependent enzyme reactions, e.g., catalysis amino-2,1-propanol to propionaldehyde in the presence ethanolamine ammonia lyase as reported Babior et al., very characteristic e.s.r. spectrum is observed. It consists broad line at g∼ 2.3 and pair lines intensity ratio approximately 2:1, split 7–14 mT, centred about g= 2. Schepler al. given partial explanation for this four other similar results, basing their interpretation on...

The water-soluble largely planar 5,10,15,20-tetra-(4-methylpyridinium)porphyrin and 5,10,15,20-tetra-(3-methylpyridinium)porphyrin as well their copper(II) chelates copper(II)tetra(2,3-N-methylpyridinium)porphyrazine bind to calf thymus DNA in aqueous electrolyte solution. Evidence for the intercalative binding of dye molecules has been obtained from e.s.r. spectral data on pressed films containing chelates. result is diagnostic intercalation tetracationic metallo-macrocyclic into DNA....

The title complex [CoII(tspc)] is an efficient catalyst for the oxidation of hydrazine, hydroxylamine, or cysteine in aqueous solution by molecular oxygen. E.s.r. measurements have been made on frozen solutions containing complexes with dioxygen, and hydroxylamine as a precursor to similar substrate exposed hydrazine involves initial formation 1 : adduct between which reacts oxygen yield products [CoII(tspc)].

The Large Synoptic Survey Telescope (LSST) camera will be made as a mosaic assembled of 189 large format Charge Coupled Devices (CCD). They are n-channel, 100 micron thick devices operated in the over depleted regime. There 16 segments, 1 million pixels each, that read out through separate amplifiers. image quality and readout speed expected from LSST translates into strict acceptance requirements for individual sensors. Prototype sensors preproduction CCDs were delivered by vendors they...

The silica polymorphs, silicalite 1, sodalite, dodecasil 3C and 1H, share an inability to adsorb the cationic dye methylene blue from aqueous solution owing absence of surface acid sites on their framework structure. uptake by zeolite ZSM-5 is linearly proportional its aluminium content. mechanism adsorption process involves replacement hydrogen ions outside crystal upon which exists in monomeric form. Samples type material with a relatively low ion content contain significant quantities 1.
