beta-Thalassemic mice provide a useful model for studying the pathophysiology of human beta-thalassemia in that one can perform experiments that are difficult to perform in humans. The ease of access to beta-thalassemic mouse marrow provided the opportunity to explore the cause of the ineffective erythropoiesis that characterizes severe beta-thalassemia in mouse and man. We hypothesized that th...

Sclerotinia sclerotiorum is a phytopathogenicfungus that attacks more than 400 plant species of them medicinal plant. In this study the extract obtained from basal stalk rot of Helianthus annuus L., attacked by S. sclerotiorum, was subjected to the analysis of FTIR to identify the presence of beta-glucan. FT-IR spectrum showed four ranges of bands in 890 cm-1, two overlap band in 1047 and 1078 ...

In time-constraint activities, such as sports, it is advantageous to be prepared to act even before knowing precisely what action will be needed. Here, we studied the relation between neural oscillations during motor preparation and amount of uncertainty about the direction of the upcoming target. Ten right-handed volunteers participated in a cued center-out task. A brief visual cue identified ...

The basal ganglia may play an important role in the control of motor scaling or effort. Recently local field potential (LFP) recordings from patients with deep brain stimulation electrodes in the basal ganglia have suggested that local increases in the synchronisation of neurons in the gamma frequency band may correlate with force or effort. Whether this feature uniquely codes for effort and wh...

The processing of social information in the human brain is widely distributed neuroanatomically and finely orchestrated over time. However, a detailed account of the spatiotemporal organization of these key neural underpinnings of human social cognition remains to be elucidated. Here, we applied functional magnetic resonance imaging (fMRI) and magnetoencephalography (MEG) in the same participan...

We previously showed that in a two-alternative choice (2AC) task, olfactory bulb (OB) gamma oscillations (approximately 70 Hz in rats) were enhanced during discrimination of structurally similar odorants (fine discrimination) versus discrimination of dissimilar odorants (coarse discrimination). In other studies (mostly employing go/no-go tasks) in multiple labs, beta oscillations (15-35 Hz) dom...

Problem Addressed. Decoding of silent vocalization would be enhanced by detecting vocalization onset. This is necessary in order to improve decoding of neural firings and thus synthesize near conversational speech in locked-in subjects implanted with brain computer interfacing devices. Methodology. Cortical recordings were obtained during attempts at inner speech in a mute and paralyzed subject...

26 27 We previously showed that in a 2-alternative choice (2AC) task, olfactory bulb (OB) 28 gamma oscillations (~70 Hz in rats) were enhanced during discrimination of structurally 29 similar odorants (fine discrimination) vs. discrimination of dissimilar odorants (coarse 30 discrimination). In other studies (mostly employing go/no-go tasks) in multiple labs, beta 31 oscillations (15-35 Hz) dom...
