  1. Vitiligo: ocular and electrophysiological findings.

    PMID 20467388

    The results of the fundus examination were normal, showing no characteristics that might be considered typical of vitiligo. Sixteen patients had an altered VEP (9 with amplitude reduction, 7 with amplitude reduction and increased latency); 4 patients showed only an Arden Index (AI) > or =180; and 4...
  2. [Updates on ossification on posterior longitudinal ligament. Electrophysiological diagnosis of spinal cord dysfunction in ossification of po...

    Clinical calcium 19(10):1435 (2009) PMID 19794251

    It is extremely difficult to make a correct diagnosis of the responsible lesion in multilevel continuous and mixed-type ossification of the posterior longitudinal ligament (OPLL) even after magnetic resonance imaging (MRI) . Understanding the function of the preoperative spinal cord is crucial for s...
  3. [Changes in brain bioelectrical activity during xenon anesthesia in neurosurgical patients].

    Anesteziologiia i reanimatologiia (2):31 (2010) PMID 20524327

    Xenon is a promising anesthetic agent in neurosurgery. However, there is now little evidence on the effect of xenon at anesthetic concentrations on brain electrical activity, which limits its use in neurosurgical patients. Changes in brain bioelectrical activity were studied in patients with skull b...
  4. Manual whole-cell patch-clamping of the HERG cardiac K+ channel.

    Methods in Molecular Biology 691:151 (2011) PMID 20972752

    Delayed ventricular repolarization, as measured by a prolongation of the QT interval on the electrocardiogram, is a major safety issue in the drug development process. It is now recognized that most cases of drug-induced QT prolongation arise from direct pharmacological inhibition of the human ether...
  5. Queen volatiles as a modulator of Tetragonisca angustula drone behavior.

    Journal of Chemical Ecology 37(11):1255 (2011) PMID 22081302

    We established meliponaries, in different habitats, with T. angustula virgin queens during the main drone reproduction period. Eight DCAs were observed in urban areas, and all established outside or near colonies containing at least one virgin queen. The accumulation of drones in the DCAs occurred f...
  6. Ophthalmological and electrophysiological features of Parkinson's disease.

    Klinika oczna 112(7-9):247 (2010) PMID 21117366

    Based on available literature, the authors describe the most frequent ocular diseases and symptoms, as well as bioelectrical dysfunction of the visual pathway in patients with Parkinson's disease (PD). Data published in literature available in PubMed library. The most often ocular diseases, symptoms...
  7. Electrical activity of Asian catfish Clarias macrocephalus (Claridae, Siluriformes) during spawning behavior.

    Doklady Biological Sciences 429:554 (2009) PMID 20170072
