We determine Johnson B,V and Cousins R, I photometric CCD magnitudes for the afterglow of GRB 021211 during the first night after the GRB trigger. The afterglow was very faint and would have been probably missed if no prompt observation had been conducted. A fraction of the so-called “dark” GRBs may thus be just “optically dim” and require very deep imaging to be detected. The early-time optica...

We have collected and analyzed data taken in different spectral bands (from X-ray to optical and infrared) of the field of GRB 031220 and we present results of such multiband observations. Comparison between images taken at different epochs in the same filters did not reveal any strong variable source in the field of this burst. X-ray analysis shows that only two of the seven Chandra sources ha...

Rapid eye movement (REM) sleep occurs throughout a relatively large proportion of early development, and normal REM activity appears to be required for healthy brain development. The eye movements (EMs) observed during REM sleep are the most distinctive characteristics of this state. EMs are used as an index of neurological function postnatally, but no specific indices of EM activity exist for ...

We summarize the spectral characteristics of a sample of 22 bright γray bursts detected with the γ-ray burst sensors aboard the satellite Ginga. This instrument employed a proportional and scintillation counter to provide sensitivity to photons in the 2 400 keV range, providing a unique opportunity to characterize the largely unexplored X-ray properties of γ-ray bursts. The photon spectra of th...

Diets enriched in ornithine 2-oxoglutarate (ornithine alpha-ketoglutarate; OKG) improve immune status during stress. We described previously the ability of OKG to increase the respiratory burst in polymorphonuclear neutrophils (PMNs), but the underlying mechanisms remain unclear. OKG is usually recognized as generating glutamine, arginine and polyamines. The aim of the present study was first t...

Infraslow activity represents an important component of physiological and pathological brain function. We study infraslow activity (<0.1 Hz) in 41 patients with postanoxic coma after cardiac arrest, including the relationship between infraslow activity and EEG power in the 3-30 Hz range, using continuous full-band scalp EEG. In all patients, infraslow activity (0.015-0.06 Hz) was present, irres...

OBJECTIVE The effects of nitric oxide donor SNAP and nitric oxide inhibitors L-NMMA and AG on the functions of neutrophils in patients with Behçet's Disease (BD) were investigated in vitro. METHODS Oxidative burst and phagocytosis of neutrophils were evaluated by flow cytometry in patients with Behçet's disease (n = 32), inflammatory (n = 17) and healthy controls (n = 14), in the presence of ...

We report on ground-based and HST(+STIS) imaging of the afterglow and host galaxy of the Gamma-Ray Burst (GRB) of March 5 2002. The GRB occurred in a R = 25.17 ± 0.14 galaxy, which apparently is part of an interacting system. The lightcurve of the optical afterglow shows a rebrightening, or at least a plateau, 12–16 days after the gamma-ray event. U BV RIK ′ multi-band imaging of the afterglow ...

PURPOSE The aim of this study is to evaluate the efficacy of posterior indirect reduction and pedicle screw fixation without laminectomy for the treatment of Denis type B thoracolumbar burst fractures with incomplete neurologic deficit. METHODS From March 2008 to May 2012, 36 consecutive patients of Denis type B thoracolumbar burst with incomplete neurologic deficit were enrolled. All of the ...
