Cortical potentials related to decision-making: comparison of two types of go/no-go decision 总被引:2,自引:0,他引:2
The S1-S2 go/no-go reaction time task has been frequently used to assess volitional inhibition. In this study our aim was to compare the ERPs elicited by S1 and S2 by using a modified S1-S2 paradigm which involved a two-stage go/no-go decision. The go and the no-go S1 ERPs did not differ substantially, and both displayed a prominent negativity with peaks at 260 ms (S1N260) and at 330 ms (S1N330) post-S1. The S1N260 was similar to the N2 from no-go S2 trials. Since after all three types of stimuli, movement is not required and is inappropriate, this negativity may represent the correlate of the voluntary decision to suppress movement. Later, the S1 ERPs were dominated by frontal negativity (S1N330), probably reflecting further processes related to response preparation, while the S2 ERPs displayed a large central and parietal positivity (P3), probably reflecting the processes of evaluation of response accuracy. 相似文献

The paper presents a review study on score systems in current emergency surgery including its classification, application and value, based on the experiences of other authors, the paper suggests application of score systems in different phases of polytraumatized patients treatment (in prehospital, as well as in early and late phases of the inpatient period). The paper also points out certain objective difficulties in everyday scoring of patients at the Department of the Emergency Surgery (daily engagement, computer center, etc.). As a conclusion, the authors present their opinion indicating that in absence of introduction of these systems into the practice, the approach to a polytraumatized patient cannot be adequate. 相似文献

The arterial vascularization of the right half of pancreas is structured as arcades: anterior, intermediate and posterior pancreatico-duodenal, and prepancreatic arcade. These blood vessels present as a complex of anastomoses between the large viceral arteries: the coeliac trunk and the superior mesenteric artery. The paper describes variations of origin, course and branching of the arcades' constituents, relevant for the contemporary surgery of pancreas and adjacent organs. A particular attention was drawn to the two anatomical entities: retropancreatic fibrous band and arterial vascularization of the major duodenal papilla. 相似文献

This paper has analyzed respiratory syncytial virus lower respiratory tract infections in 201 hospitalized children. In children with wheezing, erythrocyte sedimentation rate (ESR) was significantly higher in those with pneumonia than with syndroma pertussis, while the white blood cell (WBC) count was significantly lower in patients with bronchitis than in those with bronchiolitis and syndroma pertussis. Bronchodilatators were applied in 75.6% and corticosteroids in 20% of patients. Ten patients were ventilated. Fatal disease outcome was observed in one infant. Twelve consecutive-year study of respiratory syncytial virus (RSV) infections showed that 27.3% of these diseases were bronchiolitis and pneumonia. 相似文献

Nitric oxide (NO) derived intracellularly from L-arginine (Arg) is indispensable for optimalgeneration of lymphokine-activated killer (LAK) cell activity in rodents. Still unclear, however, is its role in humans. To address this question human peripheral blood mononuclear cells (PBMC) from healthy donors were cultured in L-arginine free medium supplemented with recombinant interleukin-2 (rIL-2) and in the presence of exogenous L-arginine analog NG-monomethyl-L-arginine (NMMA), a specific inhibitor of the NO synthetic pathway. Cultured PBMC were tested for cytotoxic activity, proliferative capacity, and expression of phenotypic and activation markers (CD3, CD4, CD8, CD16, CD56 and CD25). Culture supernatants were assayed for nitrite (NO2-) and tumor necrosis factor-alpha (TNF-alpha) production. We found that NMMA inhibits the generation of optimal LAK cell activity when no exogenous Arg is supplied. Similar effects were also observed on proliferation, expression of IL-2 receptor induced upon rIL-2 stimulation and on TNF-alpha production. Sodium nitroprusside (SNP), used as a source of exogenous NO could not overcome this effect of NMMA on LAK cell activity. NO2- production was virtually undetectable in culture supernatants. Thus, NMMA affects in an NO-independent manner rlL-2 induced LAK activity in human PBMC. 相似文献

Two outbreaks of typhoid fever caused by Salmonella typhi of the same phagotype (A, biotype II) and antibiotic susceptibility are reported. Both occurred during the war in Bosnia and Herzegovina. The first outbreak appeared among the refugees from the town of Jajce. The second outbreak appeared among the inhabitants in the village of Vidosi near Livno. This report describes main clinical, epidemioloigcal and laboratory findings for 22 patients treated in Split University Hospital, Croatia, in the period November 1992–January 1993. Possible epidemiological connections between those two outbreaks are discussed. 相似文献

We report three newborns with different manifestations ofUreaplasma urealyticum infection; a term newborn with acute neonatal pneumonia and two very low birth weight infants with bronchopulmonary dysplasia and osteomyelitis of the femur, respectively. The association ofU. urealyticum with acute and chronic respiratory disease in term and preterm newborns has recently been reported. Our two cases are similar to other case reports from the literature, but we were unable to find any previous reports of osteomyelitis due toU. urealyticum in the premature babies. Isolation ofU. urealyticum in pure culture from the blood was considered to be related to local infection in all three patients. All patients were cured by erythromycin. 相似文献

Summary A nine-weeks-old infant with haemophilia A developed an intracerebral haematoma. Intracranial operation and removal of the haematoma were performed safely under the cover of highly potent AHF cryoprecipitate. Computerized tomography of the brain is very useful for neurosurgical care of the haemophiliac patients as a noninvasive and atraumatic method of examination. The literature of intracranial operations in infants with haemophilia A under the age of one year is reviewed. 相似文献
