The primary function of a cognitive radio is to detect idle frequencies or sub-bands, not used by the primary users (PUs), and allocate these frequencies to secondary users. The state of the sub-band at any time point is either free (unoccupied by a PU) or busy (occupied by a PU). The states of a sub-band are monitored over L consecutive time periods, where(More)
Management of supra-tentorial intra-cranial abscess: A review of two hundred cases. (1967) Neurological syndromes produced by sphenoid sinus abscess with neuroloradiologic review of pituitary abscess. Summary Eight patients with hypocalcaemia who presented with frank or latent tetany due to parathyroid insufficiency or nutritional osteomalacia were studied.(More)
This study illustrates the outcome and cost-effectiveness of anterior temporal lobectomy (ATL) among patients with medically refractory temporal lobe epilepsy (TLE) treated in an epilepsy center in Kerala, South India. Patients for ATL were selected on the basis of a noninvasive protocol comprising clinical, interictal scalp electroencephalogram (EEG),(More)
The neuropathological features of temporal lobe epilepsy were studied utilising 100 consecutive surgical specimens from patients with medically refractory complex partial seizures. A wide spectrum of neuropathological changes was recorded in 98 specimens. Fifty-eight specimens showed features of Ammon's horn sclerosis. Diffuse accumulation of corpora(More)
Several studies using animal models have suggested that the effects of nutritional insult on the developing brain are long-lasting and lead to permanent deficits in learning and behavior. Malnutrition can refer to the availability of all the nutrients but in insufficient quantities or it may imply that one or more of essential nutrients is either missing or(More)
BACKGROUND Elevated circulating norepinephrine (NE) has been implicated in causing the profound beta-adrenergic receptor (betaAR) downregulation and receptor uncoupling that are characteristic of end-stage human dilated cardiomyopathy, a process mediated in part by increased levels of beta-adrenergic receptor kinase (betaARK1). To explore whether chronic(More)
BACKGROUND Anesthetic-induced suppression of cortical electrical activity is a major concern during epilepsy surgery. Dexmedetomidine (Dex) has been recently evaluated in a few small series for its effect on the electrocorticographic spikes intra-operatively. METHODS In this prospective study, electrocorticogram (ECoG) was monitored during dexmedetomidine(More)
