Astrocytes exhibit excitability based on variations of their intracellular Ca2+ concentrations, which leads to glutamate release, that in turn can signal to adjacent neurons. This glutamate-mediated astrocyte-neuron signaling occurs at physiological intracellular Ca2+ levels in astrocytes and includes modulation of synaptic transmission. The mechanism(More)
Astrocytes can modulate synaptic transmission by releasing glutamate in a Ca(2+)-dependent manner. Although the internal Ca(2+) stores have been implicated as the predominant source of Ca(2+) necessary for this glutamate release, the contribution of different classes of these stores is still not well defined. To address this issue, we cultured purified(More)
To define reliable Doppler parameters in mural arteries of affected bowel loops for quantitative assessment of Crohn disease (CD) activity in pediatric population and compare Doppler parameters with Pediatric Crohn Disease Activity Index (PCDAI). Thirty-four pediatric patients (7 with inactive, 27 with active disease of different severity; 13 male and 21(More)
BACKGROUND Priapism, persistent erection without arousal, can be classified into low-flow (venous or ischemic) and high-flow (arterial or non-ischemic). The diagnosis of high-flow priapism can be confirmed by colour Doppler and arteriography and it is usually treated by the endovascular embolization. CASE REPORT We present a case of a 20-year-old man with(More)
Infantile hepatic hemangioendothelioma (IHHE) is the most common benign hepatic tumor in children (12% of hepatic tumors), that usually responds well to therapy and has low mortality rates. In extremely rare cases of diffuse tumors resistant to therapy, size and blood flow can lead to cardiorespiratory failure and death. A 3-month-old male infant presented(More)
