OBJECTIVE Breath holding spells (BHS) are common paroxysmal non-epileptic events in the pediatric population which are very stressfull despite their harmless nature. There has been no specific treatment found for the spells yet. The aim of this study was to evaluate the efficacy of piracetam (2-oxo-l-pyrrolidine) on these children. MATERIALS & METHODS In this randomized double blind clinical ...

It has been justifiably questioned if the Black Hole Candidates (BHCs) have “hard surface” why Type I X-ray bursts are not seen from them (Narayan, 2005). It is pointed out that a “physical surface” need not always be “hard” and in could be “gaseous” in case the compact object is sufficiently hot(Mitra, 2005a,b). Even if a “hard surface” would be there, presence of strong strong intrinsic magne...

In this paper, we investigate the structures of galaxies which either have or have had three BHs using N -body simulations, and compare them with those of galaxies with binary BHs. We found that the cusp region of a galaxy which have (or had) triple BHs is significantly larger and less dense than that of a galaxy with binary BHs of the same mass. Moreover, the size of the cusp region depends st...

BACKGROUND Little is understood about the conceptual relationship of depression and quality of life (QoL). Judgments concerning both, implicitly or explicitly, involve a time perspective. The aim of this study was to test de Leval's theoretical model linking depression and QoL with a time perspective. The model predicts that changes in cognitions about one's past, present and future QoL, will b...

We describe a model-independent integral constraint which defines an upper limit to the allowed degree of evolution in the ratio of black hole (BH) mass to host galaxy luminosity or mass, as a function of redshift. Essentially, if the BH/host ratio is excessive at redshift z, then it would imply that the total mass density in BHs above some Mmin BH is larger at that redshift than at z = 0, whic...

A 10-month-old girl was referred to our institution for evaluation of recurrent loss of consciousness that occurred for 30 seconds 1 to 3 times a day. The seizures occurred after crying, pain, or frustration. Because of toniclike seizures before the loss of consciousness, the girl was initially remitted to pediatric neurology, where a movieassisted electroencephalography was registered (Movie I...
