Cortical oscillations in the beta band (13-35 Hz) are known to be modulated by the GABAergic agonist benzodiazepine. To investigate the mechanisms generating the approximately 20-Hz oscillations in the human cortex, we administered benzodiazepines to healthy adults and monitored cortical oscillatory activity by means of magnetoencephalography. Benzodiazepine increased the power and decreased th...
The present study aimed to explore the modulation of frequency bands (alpha, beta, theta) underlying the positive facial expressions classification advantage within different post-stimulus time intervals (100-200 ms, 200-300 ms, 300-400 ms). For this purpose, we recorded electroencephalogram (EEG) activity during an emotion discrimination task for happy, sad and neutral faces. The correlation b...
The O antigen unit of Pseudomonas aeruginosa serotype O5 is a complex trisaccharide containing 2-acetamido-3-acetiminido-2, 3-dideoxy-beta-D-mannuronic acid, 2-acetimido-3-acetimido-2, 3-dideoxy-beta-D-mannuronic acid, and 2-acetimido-2, 6-deoxy-beta-D-galactosamine. Specific knockout mutations in the putative UDP-D-N-acetylglucosamine (UDP-D-GlcNAc) epimerase gene, wbpI, or the putative UDP-D-...
We report data showing that the integrin receptor complex in chickens contains several discrete heterodimers all sharing the beta 1-integrin subunit combined separately with different alpha-subunits. Using antisera to synthetic peptides based on cDNA sequences of chicken and human alpha-integrin subunits to analyze the integrin complement of avian and mammalian cells, we show that band 2 of the...
