Results. Of the 172 patients, 75 (43.6%) developed angina (n=56) or ST-segment depression (n=30) during atropine administration. Eight of the 23 patients (35%) who underwent two tests exhibited scintigraphic
GSK1838705A ischemia (SDS >= 2) on only the test with atropine. Furthermore, the SDS was significantly greater on SPECT imaging with atropine (5.6 +/- 4.5 vs. 3.1 +/- 2.8; P=.0001).
Conclusions. One-third of patients who met scintigraphic criteria for ischemia at the end of submaximal exercise testing and after atropine administration would not have met those criteria without administration of the drug.”
“Hyperglycemic status may be rarely complicated by Epilepsia partialis continua (EPC) that usually responds to metabolic normalization. Anti-glutamic acid decarboxylase antibodies (GAD-Ab) play a pivotal role in the autoimmune process that leads to clinical onset of type 1 diabetes mellitus (T1DM). GAD-Ab have been recently reported in association with rare forms of refractory epilepsy, with or without association to T1DM. Here we describe a young patient who developed EPC five months after T1DM onset; GAD-Ab were detected in his cerebrospinal fluid with evidence of oligoclonal bands. His epileptic disorder evolved over time into drug-resistant epilepsy with continuous spike-waves during slow sleep and severe behavioral impairment. The
JQ1 solubility dmso role of both metabolic imbalance and GAD autoimmunity is discussed.”
“Cigarette smoking condensate (CSC) contains oxidant compounds able to generate superoxide. GANT61 datasheet The aim of the present study was to investigate the effect
of the exposure to CSC on: (1) free radical production, (2) the gene expression of the antioxidant enzymes Cu-Zn superoxide dismutase (SOD1), Mn superoxide dismutase (SOD2), Glutathione Peroxidase (GPx), and catalase (CAT), and (3) cell survival in human neuroblastoma SH-SY5Y cells. The results showed that exposure (24 h) to different concentrations (10-150 mu g/ml) of CSC caused a dose dependent cell injury that was coupled to the maximal increase of free radical production. These events were prevented by the addition to the incubation medium of the scavenger Vitamin E (50 mu M). Furthermore, CSC exposure caused a reduction of the gene expression of the antioxidant enzymes SOD1, SOD2, GPx, and CAT that was counteracted by Vitamin E (50 mu M). These results suggest that CSC exposure can induce a free radical overcharge that may be responsible for the inhibition of antioxidant enzymes expression and cell injury in SH-SY5Y human neuroblastoma cells. In fact the scavenger vitamin E can block both cell injury and inhibition of SOD1, SOD2, GPx, and CAT induced by CSC exposure.”
