Increased MPV may be a result of dissection. In addition, it may be a risk factor for dissection-related stroke. Our study supports the

notion that platelet reactivity is important in the pathogenesis of the cervicocephalic artery dissections, especially in vertebral artery dissections.”
“The morphologies of the fullerene targets and the ablated fullerenes to determine the optimal conditions of excitation of the C-60-containing targets have been analyzed. The optimization of fullerene-containing plasma conditions allowed the enhanced harmonic generation in these plasmas using laser radiation of different wavelengths, pulse durations, and phase modulation. A comparison between the harmonic generation in single-atom/ion-containing plasmas (using bulk selleck screening library carbon, silver, and indium targets) and fullerene-rich plasma plumes showed better conversion efficiency for the latter medium. The influence of phase modulation of the fundamental radiation in fullerene plasmas on the spectral properties of harmonics has been studied. (C) 2009 American Institute of Physics.

“Craniocervical PD-1/PD-L1 cancer arterial dissection is a frequent cause of childhood arterial ischemic stroke requiring

prompt diagnosis and treatment. However, there is no universal guideline for diagnostic cerebrovascular imaging in children. We assessed the role of time-of-flight magnetic resonance angiography in diagnosing craniocervical arterial dissection. We included children (1 month to 18 years) with craniocervical arterial dissection and ischemic stroke from January 1998 to June 2007. Institutional protocol required magnetic resonance imaging (MRI)/magnetic resonance angiography for all ischemic stroke cases and conventional cerebral angiography if magnetic resonance Epigenetic 抑制剂 angiography showed any arteriopathy. Among 233 ischemic stroke cases, craniocervical arterial dissection was diagnosed in 13 patients (5.6%; 10 males), with a mean age of 7.5 years. Initial time-of-flight magnetic resonance angiography missed dissection in 8 patients

(61.5%) because the neck vessels were not scanned (n = 2), of suboptimal technique (n = 3), and of diagnostic error (n = 3). T1 fat-saturated MRI and contrast-enhanced magnetic resonance angiography were not performed in 12 patients. If suspicion for arterial dissection is high, T1 fat-saturated neck imaging and contrast-enhanced magnetic resonance angiography should be considered to maximize detection.”
“Rapid biliary stent clogging is poorly documented in the literature. We present two case reports in a 12-year ERCP series and highlight the challenges involved.”
“In this paper, we investigate warm electron injection (WEI) as a mechanism for NOR programming of double-gate SONOS memories through two dimensional (2D) full-band Monte Carlo simulations. WEI is characterized by an applied V-DS smaller than 3.
