Interactions between neurosteroids and GABA receptors have attracted particular attention in the supraoptic nucleus (SON). Although GABA(A) receptors (GABA(A)R) mediate a sustained tonic inhibitory current (I(tonic)), as well as conventional phasic inhibitory postsynaptic currents (IPSCs, I(phasic)) in the SON, whether the steroid modulation on I(tonic) is present in SON magnocelluar neurosecre...

In-depth interviews with 30 sons actively involved in caring for a parent with dementia expand the understanding of sons' caregiving experiences. The within-group analysis revealed common themes that emerged from the narratives--duty, acceptance, taking charge, common emotions, and work flexibility--as well as common issues--loss, sibling relationships, role reversal, coping strategies, and pos...

An Intelligent Distributed Antenna System (IDAS) fed by a multiple Base Transceiver Station (BTS) has the ability to distribute the radio resources over a given geographic area. To enable an efficient distribution of radio resources amongst the antenna modules, a server is utilized to dynamically allocate the remote antenna modules to the BTSs using a Self-Optimized Network (SON) algorithm. Mon...

Potassium channels are trans-membrane proteins, which selectively transport K+ ions across cell membranes and play a key role in regulating the physiology of excitability cells and signal transduction pathways. Bothutous Schach (BS) scorpion venom consists of several polypeptides that could modulate ion channels. In this study, the effects of BS crude venom on passive and active electrophysiolo...

To investigate the effects of novel intravenous general anesthetic propofol on membrane electrophysiological characteristics and action potential (AP) of the supraoptic nucleus (SON) neurons and possible ionic mechanisms, intracellular recordings were conducted in SON neurons from the coronal hypothalamic slice preparation of adult male Sprague Dawley (SD) rats. The results showed that bath app...

Noradrenaline and serotonin are known to control arginine-vasopressin (AVP) and oxytocin (OT) secretion in the systemic circulation. The aim of the current study was to investigate whether these monoamines are also able to influence AVP and OT expression in the paraventricular (PVN) and supraoptic nuclei (SON). To test this hypothesis, we used the Tg8 transgenic mice KO for the monoamine oxidas...

Empirical evidence suggests that parents who have themselves inherited from their own parents are more likely to leave an estate to their children even after controlling for income, wealth and education. This implies an indirect reciprocal behavior between three generations by transmitting the attitude towards bequeathing from one generation to the next. We incorporate such an intergenerational...

A father and son presented ten years apart with a fourth ventricle ependymoma. The history, imaging and pathology are presented and the aetiology of familial ependymoma discussed.

Recent advances in neuronal culturing techniques have supplied a new set of tools for studying neural tissue, providing effective means to study molecular aspects of regulatory elements in the supraoptic nucleus of the hypothalamus (SON). To combine molecular biology techniques with electrophysiological recording, we modified an organotypic culture protocol to permit transfection and whole cell...

Previous studies implicated potential value of mismatch negativity (MMN) in predicting recovery of consciousness in patients with disorders of consciousness (DOC). We have adopted a novel MMN evoked by subject's own name (SON), a self-referential stimulus thought to be powerful in evoking residual brain activity, and examined the correlation between the MMN and recovery of consciousness in pati...
