Twenty eight patients with unilateral cervical radiculopathy were studied by somatosensory evoked potentials (SEPs) from nerve stimulation at the wrist and from skin stimulation at the first, third or fifth finger depending on the root involved. In order to evaluate the reliability of various "radicular SEP patterns" as described in the literature, absolute latencies and side-to-side difference...

A four quasiparticle high-K isomer with a meanlife of 45~2! ms has been identified at 1451 keV in Ta, populated in the Yb(B,a3n! Ta reaction. The isomer decays into a rotational band which is associated with the two-quasiparticle 9 isomer at 75.3 keV. Analysis of the branching ratios within that band and the magnetic moment for the 9 isomer, supports the configuration assignment to the 9 isomer...

We have used single- and double-labeling immunfluorescence and reverse transcription-polymerase chain reaction (RT-PCR) methods to examine expression of P2X receptor subtypes on microglial cells of brain in late embryonic and postnatal rat, in the N9 microglial cell line and primary cultured microglial cells. P2X1, P2X4, and P2X7 receptors were shown on microglial cells from late embryonic day ...

Angleson, J. K. and W. J. Betz. Intraterminal Ca and spontaneous transmitter release at the frog neuromuscular junction. J Neurophysiol 85: 287–294, 2001. We investigated the relationship between intraterminal Ca concentration ([Ca]i) and the frequency of miniature end plate potentials (MEPPs) at the frog neuromuscular junction by use of ratiometric imaging of fura-2-loaded nerve terminals and ...

Objective: The aim of this study is to confirm the effectiveness of auditory brain-stem responses (ABRs) and somatosensory evoked potentials (SEPs) in the diagnosis of brain death (BD). Methods: ABRs and SEPs were recorded at the same session in 130 BD patients (age range 8–77 years, 81 male and 49 female). Twentyfour cases were submitted to serial recordings from preterminal conditions through...

Microglial activation is involved in a variety of neurological disorders, and overactivated microglial cells can secrete large amount of proinflammatory factors and induce neuron death. Therefore, reducing microglial activation is believed to be useful in treating the disorders. In this study, we used 10 ng/ml lipopolysaccharide plus 10 U/ml interferon γ (LPS/IFNγ) to induce N9 microglial activ...

Resistance to neuraminidase inhibitors (NAIs) is a growing problem in battle against influenza A virus. However, little is known about the resistance of viruses isolated from dabbling ducks, the natural reservoir of the influenza virus. To our knowledge, no low-pathogenic avian influenza (LPAI) virus resistant to NAIs has been detected. The aim of this study was to investigate mallard isolates ...

The gas-phase acidities of adenine, 9-ethyladenine, and 3-methyladenine have been investigated for the first time, using computational and experimental methods to provide an understanding of the intrinsic reactivity of adenine. Adenine is found to have two acidic sites, with the N9 site being 19 kcal mol(-1) more acidic than the N10 site; the bracketed acidities are 333 +/- 2 and 352 +/- 4 kcal...

The ability of a taurine prodrug, ethane β-sultam, to reduce cellular inflammation has been investigated, in vitro, in primary cultures of alveolar macrophages and an immortilised N9 microglial cell line and in vivo in an animal model of inflammation and control rats. Ethane β-sultam showed enhanced ability to reduce the inflammatory response in alveolar macrophages, as assayed by the lipopolys...
