Sleep and Epilepsy: A Complex Interplay.

In this review we look to provide an overview of the complex interactions between sleep and epilepsy, and how knowledge of the interplay between the two can help in guiding management of disorders in both areas.

Cough syncope in a 43-year-old woman with glomus jugulare tumor.

We present an unusual case of recurrent cough syncope in a 43-year-old woman, which was initially thought to be seizures. Syncopal episodes were triggered by paroxysms of cough and were characterized by unresponsiveness and myoclonic jerks in her extremities. She had a left-sided glomus jugulare tumor that extended into the posterior cranial fossa with evidence of worsening communicating hydrocephalus on brain imaging.

Health & Demographic Surveillance System Profile: The Birbhum population project (Birbhum HDSS).

The Birbhum HDSS was established in 2008 and covers 351 villages in four administrative blocks in rural areas of Birbhum district of West Bengal, India. The project currently follows 54 585 individuals living in 12557 households. The population being followed up is economically underprivileged and socially marginalized.

Transgenic analysis of GFAP promoter elements.

Transcriptional regulation of the glial fibrillary acidic protein gene (GFAP) is of interest because of its astrocyte specificity and its upregulation in response to CNS injuries. We have used a transgenic approach instead of cell transfection to identify promoter elements of the human GFAP gene, since previous observations show that GFAP transcription is regulated differently in transfected cultured cells from in the mouse. We previously showed that block mutation of enhancer regions spanning from bp -1488 to -1434 (the C1.

Efficacy of alternate-day versus everyday dosing of atorvastatin.

Background: Atorvastatin has a longer duration of action than other hydroxymethylglutaryl coenzyme A reductase inhibitors.

Objectives: The objective was to evaluate the efficacy of alternate day vs. daily dosing of atorvastatin for the treatment of hyperlipidemia.

Micro-albuminuria: a predictor of short-term mortality in acute ischaemic stroke.

We studied 89 non-diabetic patients of acute ischaemic stroke, confirmed by imaging, admitted within 24 hours of onset, to investigate the prevalence and significance of micro-albuminuria (MA) as a predictor of in-hospital mortality. Two control groups consisted of 70 patients with non-stroke chronic neurological diseases and 60 age- and sex- matched healthy individuals. Spot urinary albumin-to-creatinine ratio was measured in first morning sample on days 1, 4 and/or 7.

Dopaminergic modulation of local network activity in rat prefrontal cortex.

Dopamine modulates prefrontal cortex excitability in complex ways. Dopamine's net effect on local neuronal networks is therefore difficult to predict based on studies on pharmacologically isolated excitatory or inhibitory connections. In the present work, we have studied the effects of dopamine on evoked activity in acute rat brain slices when both excitation and inhibition are intact.

NR2B antagonists restrict spatiotemporal spread of activity in a rat model of cortical dysplasia.

Freeze-lesion-induced focal cortical dysplasia in rats closely resembles human microgyria, a neuronal migration disorder associated with drug-resistant epilepsy. Alterations in expression of N-methyl-D-aspartate receptors (NMDARs) containing NR2B subunits have been suggested to play a role in the hyperexcitability seen in this model. We examined the effect of NMDAR antagonists selective for NR2B subunits (Ro 25-6981 and ifenprodil) on activity evoked by intracortical stimulation in brain slices from freeze-lesioned rat neocortex.

Endogenous acetylcholine enhances synchronized interneuron activity in rat neocortex.

Application of 4-aminopyridine (4-AP) along with EAA) receptor antagonists produces gamma-aminobutyric acid (GABAA) receptor-dependent synchronized activity in interneurons. This results in waves of activity propagating through upper cortical layers. Because interneurons in the neocortex are excited by nicotinic acetylcholine receptor (nAChR) agonists, ACh may influence synchronization of these local neocortical interneuronal networks.

Effect of Sonachandi Chyawanprash and Chyawanprash Plus--two herbal formulations on immunomodulation.

The immunomodulatory effects of Sonachandi Chyawanprash and Chyawanprash Plus--two herbal formulations have been evaluated. Both the drugs increased the macrophage activity and their number indicating enhancement of non-specific immune response and reduction of chances of infection. Besides that both Sonachandi Chyawanprash and Chyawanprash Plus efficiently protected Cyclosporine A induced immunosuppression suggesting the immunoprotective role of the aforesaid herbal formulations.

Dopamine enhances spatiotemporal spread of activity in rat prefrontal cortex.

Dopaminergic modulation of prefrontal cortex (PFC) is important for neuronal integration in this brain region known to be involved in cognition and working memory. Because of the complexity and heterogeneity of the effect of dopamine on synaptic transmission across layers of the neocortex, dopamine's net effect on local circuits in PFC is difficult to predict. We have combined whole cell patch-clamp recording and voltage-sensitive dye imaging to examine the effect of dopamine on the excitability of local excitatory circuits in rat PFC in vitro.
