The strychnine-sensitive glycine receptor (GlyR) is a member of the ligand-gated ion channel superfamily. In the adult, the GlyR is known to mediate fast inhibitory neurotransmission in the spinal cord and in the brainstem. The GlyR has also been described in the embryonic cortex from embryonic day 19 (E19) where it could participate in developmental processes, but its presence at earlier stages has not been documented. Since other neurotransmitter systems, i.e. GABA and its receptors, are known to be present during corticogenesis, we wondered if this could also be the case for glycine and its GlyR. In this study, we analyze the presence and physiological relevance of GlyR in the early development of the cortex using in vitro and ex vivo cultures of slices, patch-clamp, two photon microscopy for time lapse and for calcium imaging, immunocytochemistry and western-blot. Electrophysiological experiments confirmed the presence of GlyR mediated currents in migrating interneurons during early stages of development (E13-E15). Using in vitro labeling of interneurons we have described the pharmacological properties of glycinergic currents present in interneurons born at E13. The concentration-response curve showed an EC50 of 69 ± 12 micro M for glycine. All these currents were fully blocked by strychnine with an IC50 of 0.10 ± 0.02 micro M. Picrotoxinin and picrotin also blocked these currents, but with different potency, remaining 20 % of the current when 10 micro M of picrotin was used. Similar glycinergic currents were also observed in ex vivo preparations from Dlx5/6-Cre EGFP transgenic animals, where it was clear that GlyR expressing cells are a subpopulation of migratory interneurons. Consequently, immunostainings directed against the alpha 2 subunit of GlyR showed that 29 ± 2 % of cortical migrating interneurons, which were mainly born in the medial ganglionic eminence (MGE) at E13, express GlyR. All this evidences shows that GlyR appears earlier than ever described during cortex development and it is composed, mainly, by alpha 2 homomeric channels. It also shows that GlyR is not homogenously expressed and it is only present in a subpopulation of migrating interneurons born at a defined space-temporal window during brain development. In search for the physiological function of GlyR, two photon time lapse analysis for cell migration and calcium imaging was performed on ex vivo slices. All these studies were complemented by gain and loss of function experiments. As it has been previously described for the GABA system, we show here that GlyR play a role acting on the migratory behavior of interneurons and its effects are linked to modulation of calcium dynamic and the activity of calcium downstream targets. More in detail molecular mechanisms were analyzed by western-blot. [less ▲]

Il Grande Incendio di Salonicco (1917) e la sua ricostruzione contribuirono a ridisegnare la geografia etno-confessionale lungo il nuovo confine greco-turco, ma anche alla transizione della città da “Gerusalemme dei Balcani” a “Capitale dei profughi”. Pochi decenni prima dell’incendio che avrebbe colpito nel corpo la comunità ebraica europea – l’Olocausto – quello di Salonicco concorse ad alimentare fenomeni migratori e progetti di ricostruzione in luoghi distanti : calcando le orme dei loro correligionari centreuropei, gli ebrei di Salonicco emigrarono verso l’Europa occidentale, le Americhe. Alcuni preferirono la Palestina.Dalla fine dell’Ottocento, le persecuzioni razziali in Europa – spesso accompagnate dall’incendio dei luoghi di culto – avevano provocato regolari ondate migratorie verso questa remota provincia dell’Impero ottomano, ora sotto Mandato britannico. A ciascuna di queste ondate corrispondevano altrettante campagne insediative accomunate dallo sforzo di diverse generazioni di agronomi, architetti e urbanisti nella definizione dei caratteri e delle forme del villaggio agricolo ebraico ; « topos » prioritario nella ricostruzione delle nuove identità individuali e collettive ebraiche.Nei primi anni Venti, il riassetto geopolitico del Mediterraneo orientale rappresenta l’occasione per l’Organizzazione sionista di guidare il « ritorno degli ebrei alla loro terra d’origine » e all’agricoltura. Nella Valle di Jesreel si mette in atto un ambizioso progetto di ricostruzione e diradicamento, fisico e culturale a un tempo : un giovane architetto e urbanista di origini tedesche – Richard Kauffmann (1887-1958) – progetta numerosi villaggi agricoli, una piccola agro-città (Afula) e lo sviluppo della Baia di Haifa. La sequenza di questi progetti prefigura un precoce esperimento di pianificazione regionale pre-statale dal quale emerge la prima espressione compiuta di un’idea dello Spazio-Nazione sionista : un sistema insediativo lineare fondato sull’agricoltura, gerarchicamente organizzato e funzionalmente integrato, in cui è possibile apprezzare il grado di necessità del progetto di architettura nel quadro di una strategia di ampio respiro che stabilisce rapporti originali con la natura, la storia e l’« impianto geografico » a scala nazionale.

1. To address the question of whether endotoxaemia could be involved in the inflammatory response induced by long-term strenuous exercise, 18 male marathon runners [mean age 41 +/- 2 (SEM) years] were studied. Their performance in the marathon ranged from 2 h 46 min to 4 h 42 min. 2. Four venous blood samples were drawn: at rest, just before the race (baseline); within 15 min following the completion of the marathon; after 1 h of recovery; and the morning after the race. 3. The following humoral markers of the inflammatory response to exercise were measured: polymorphonuclear myeloperoxidase (MPO), anaphylatoxin C5a (C5a), tumour necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Plasma endotoxin was measured by a sensitive and rapid chromogenic Limulus assay. All inflammatory markers were significantly increased (P < 0.001) after the race, reaching in most cases peak values in the first blood sample drawn following the completion of the marathon [MPO, 298 +/- 19 ng/ml (SEM); C5a, 1.45 +/- 0.32 ng/ml; TNF-alpha, 20 +/- 3 pg/ml; IL-6, 88 +/- 13 pg/ml] when compared with baseline [MPO, 146 +/- 16 ng/ml (SEM); C5a, 0.27 +/- 0.2 ng/ml; TNF-alpha, 12 +/- 1.5 pg/ml: IL-6, 1.0 +/- 0.5 pg/ml]. Traces of plasma endotoxin (ranging from 5 to 13 pg/ml, with one exceptionally high value of 72 pg/ml measured in one runner) were detected in seven subjects within the first hour of recovery. An ELISA method was used to determine the endogenous IgG antibodies toward a range of Gram-negative bacterial lipopolysaccharides (LPSs) of different sizes and structures. A transient decrease in certain anti-LPS activities, mainly against rough LPS, occurred in most cases in the first blood sample drawn after the race. There was no correlation between the magnitude of the inflammatory response to exercise, as assessed by the increase in blood levels of humoral markers of inflammation, and the changes in circulating endotoxin levels of anti-LPS IgG activity following the race. 4. From these results, we conclude that the mild, transient endotoxaemia detected in some of our subjects does not play a major role in the observed inflammatory response to a marathon competition.

During the last 10 years, the conference on 'Steroids and Nervous System' held in Torino (Italy) has been an important international point of discussion for scientists involved in this exciting and expanding research field. The present review aims to recapitulate the main topics that have been presented through the various meetings. Two broad areas have been explored: the impact of gonadal hormones on brain circuits and behaviour, as well as the mechanism of action of neuroactive steroids. Relationships among steroids, brain and behaviour, the sexual differentiation of the brain and the impact of gonadal hormones, the interactions of exogenous steroidal molecules (endocrine disrupters) with neural circuits and behaviour, and how gonadal steroids modulate the behaviour of gonadotrophin-releasing hormone neurones, have been the topics of several lectures and symposia during this series of meetings. At the same time, many contributions have been dedicated to the biosynthetic pathways, the physiopathological relevance of neurosteroids, the demonstration of the cellular localisation of different enzymes involved in neurosteroidogenesis, the mechanisms by which steroids may exert some of their effects, both the classical and nonclassical actions of different steroids, the role of neuroactive steroids on neurodegeneration, neuroprotection, and the response of the neural tissue to injury. In these 10 years, this field has significantly advanced and neuroactive steroids have emerged as new potential therapeutic tools to counteract neurodegenerative events. [less ▲]

The text is related to the calculus’s main theorem learning as it is studied by students in the last year of Belgium secondary school. We make an epistemological analysis of the theorem that inspired us the set up of a situation composed of four mathematics statements and for which we need rectilinear movements with or without variable speeds, speeding and moving laws, areas, volumes and flows. The suggested strategies for these statements and the reactions will be analysed later. [less ▲]

Ce travail concerne l’apprentissage du calcul des dérivées tel qu’étudié chez des élèves de 16-17 ans aux prises avec des questions mobilisant des mouvements rectilignes, leurs vitesses variables ou non et les graphiques de leurs lois de position.
On y analyse ces questions comme composantes d’un milieu et les formes embryonnaires que prend le savoir construit dans ce contexte. Cette recherche illustre en outre en quoi consiste une praxéologie de type « modélisation » et le type particulier de discours technologique susceptible de justifier les techniques mises au point à ce stade.
