Diverse antiepileptic drugs increase the ratio of background synaptic inhibition to excitation and decrease neuronal excitability in neurones of the rat entorhinal cortex in vitro

Although most anti-epileptic drugs are considered to have a primary molecular target, it is clear that their actions are unlikely to be limited to effects on a single aspect of inhibitory synaptic transmission, excitatory transmission or voltage-gated ion channels. Systemically administered drugs can obviously simultaneously access all possible targets, so we have attempted to determine the overall effect of diverse agents on the balance between GABAergic inhibition, glutamatergic excitation and cellular excitability in neurones of the rat entorhinal cortex in vitro. We used an approach developed for estimating global background synaptic excitation and inhibition from fluctuations in membrane potential obtained by intracellular recordings. We have previously validated this approach in entorhinal cortical neurones [. Greenhill and Jones (2007a) Neuroscience 147:884-892]. Using this approach, we found that, despite their differing pharmacology, the drugs tested (phenytoin, lamotrigine, valproate, gabapentin, felbamate, tiagabine) were unified in their ability to increase the ratio of background GABAergic inhibition to glutamatergic excitation. This could occur as a result of decreased excitation concurrent with increased inhibition (phenytoin, lamotrigine, valproate), a decrease in excitation alone (gabapentin, felbamate), or even with a differential increase in both (tiagabine). Additionally, we found that the effects on global synaptic conductances agreed well with whole cell patch recordings of spontaneous glutamate and GABA release (our previous studies and further data presented here). The consistency with which the synaptic inhibition:excitation ratio was increased by the antiepileptic drugs tested was matched by an ability of all drugs to concurrently reduce intrinsic neuronal excitability. Thus, it seems possible that specific molecular targets among antiepileptic drugs are less important than the ability to increase the inhibition:excitation ratio and reduce overall neuronal and network excitability. © 2010 IBRO.

Violence against women in Ethiopia

Investigating the experience of violence against women and exploring women's coping strategies is a crucial component of re-tailoring the provision of services for victims/survivors. This article explores violence against women in the context of culture, theory of fear of violence and literature on spaces perceived to be 'safe' or 'dangerous' by women victims/survivors of violence in Ethiopia. To collect the relevant data, we conducted 14 semi-structured interviews with Ethiopian women who are victims/survivors of violence and three interviews with gender experts in Ethiopia. Our group of women suffer in 'silence' and confide only in friends and relatives. They did not resort to institutional support due to lack of awareness and general societal disapproval of such measures. This contrasts with claims by experts that the needs of these women are addressed using an institutional approach. Culture, migration status and lack of negotiating power in places of work are key factors when considering violence. The majority of the respondents in this study occupy both public and private spaces such as bars and homes and have experienced violence in those spaces. The social relations and subsequent offences they endured do not make spaces such as these safe. Education of both sexes, creation of awareness, sustainable resource allocation to support victims/survivors, ratification of the Maputo protocol and effective law enforcement institutions are some of the practical strategies we propose to mitigate the incidence of violence in Ethiopia. © 2010 Taylor & Francis.

The dynamics of movement: Toward a definition of a Latin American identity in contemporary fiction

Concha Meléndez opened up a venue for the discussion of a Latin American identity in works of literature when she implied that the great Latin American novel would gestate in the cities, the space where the typical Latin American would achieve an ideal state of consciousness and intellectual capabilities. ^ Her point of view mirrored nineteenth-century debate on a Latin American identity. Similar to her viewpoint, intellectuals of this period viewed the cities and their inhabitants of European extraction, as the ideal spaces and people on which an identity could be defined. However, the present state of urban and rural areas in Latin America demonstrates that there is no such clear-cut division of city and countryside or of their inhabitants. The dynamics of movement, from rural to urban areas, of people of diverse ethnic, and socioeconomic backgrounds, make it difficult to uphold descriptors of space, race, or culture, as sole descriptors of an identity. ^ A study of five twentieth-century novels from North and South America, La muerte de Artemio Cruz (1962), Hasta no verte Jesús mío (1969), Los ríos profundos (1981), La casa de los espíritus (1982), and Los años con Laura Díaz (1999) reveal that the dynamism of movement, between countryside, and cities of peoples of distinct races and social backgrounds, hamper the definition of a collective identity in specific spaces. As characters move, they are constantly reconfiguring their identities and creating tensions and conflicts that intensify social, racial and economic divisions in society. This makes it difficult to ascribe permanent identity descriptors, much less define a collective identity. ^ However, as writers of fiction address the malaise in Latin American societies, they have unearthed descriptors such as history, economy, land, and movement that advance a collective definition of self in these societies. Additionally, female characters have been granted a new identity. The overwhelming evidence in this study points to ‘land’ as the prime factor in the identity dilemma and suggests that a definition will not be possible until the vast landless populace is granted a space they can call home. Only then, perhaps, will Meléndez novel surface. ^
