Amplification of neuromuscular transmission by methylprednisolone involves activation of presynaptic facilitatory adenosine A(2A) receptors and redistribution of synaptic vesicles

The mechanisms underlying improvement of neuromuscular transmission deficits by glucocorticoids are still a matter of debate despite these compounds have been used for decades in the treatment of autoimmune myasthenic syndromes. Besides their immunosuppressive action, corticosteroids may directly facilitate transmitter release during high-frequency motor nerve activity. This effect coincides with the predominant adenosine A(2A) receptor tonus, which coordinates the interplay with other receptors (e.g. muscarinic) on motor nerve endings to sustain acetylcholine (ACh) release that is required to overcome tetanic neuromuscular depression in myasthenics. Using myographic recordings, measurements of evoked [H-3]ACh release and real-time video microscopy with the FM4-64 fluorescent dye, results show that tonic activation of facilitatory A(2A) receptors by endogenous adenosine accumulated during 50 Hz bursts delivered to the rat phrenic nerve is essential for methylprednisolone (03 mM)-induced transmitter release facilitation, because its effect was prevented by the A(2A) receptor antagonist, ZM 241385 (10 nM). Concurrent activation of the positive feedback loop operated by pirenzepine-sensitive muscarinic M-1 autoreceptors may also play a role, whereas the corticosteroid action is restrained by the activation of co-expressed inhibitory M-2 and Al receptors blocked by methoctramine (0.1 mu M) and DPCPX (2.5 nM), respectively. Inhibition of FM4-64 loading (endocytosis) by methylprednisolone following a brief tetanic stimulus (50 Hz for 5 s) suggests that it may negatively modulate synaptic vesicle turnover, thus increasing the release probability of newly recycled vesicles. Interestingly, bulk endocytosis was rehabilitated when methylprednisolone was co-applied with ZM241385. Data suggest that amplification of neuromuscular transmission by methylprednisolone may involve activation of presynaptic facilitatory adenosine A(2A) receptors by endogenous adenosine leading to synaptic vesicle redistribution.

Need for a continuing education program for toxoplasmosis control

The Toxoplasma gondii infection is very important from the point of view of public health and affects almost all homeothermic animal species, including birds and mammals. In this study, thirty teachers from elementary schools in the northwest area of the state of São Paulo, Brazil, were interviewed about toxoplasmosis. Their students frequented of first to fourth series of the fundamental teaching. The questionnaire with closed questions were: 1) is the cat the main transmitter of toxoplasmosis in humans?; 2) If the cat can transmit toxoplasmosis, how happens?; 3) “If the dog can transmit toxoplasmosis, how happens?”; Is there any other way to acquire toxoplasmosis?; If there are other means of transmission, which can be? After this stage, lectures of short duration were supplied about this disease and reapplied the interview form. The data were analyzed with base in descriptive statistics. We found that there was an assimilation of the concepts on the control of toxoplasmosis by the teachers. In conclusion, there is the need of implanting one continuing education program for the community in general directed to the improvement of basic concepts of toxoplasmosis control.

O Núcleo UHUU de pesquisa da performance: inter-ação e inter-locus-ação

The 'Performance Research UHUU Centre: interarts and multimedia' of Unesp Bauru is a possibility, among countless attempts, to break off the distance between the show and the audience, imposed by the classic dramaturgy. Seeking for re-establishing the vital energy dialogue between the artist and his public, the performance art is focused, which, opposed to the theatre orthodox conceptions (which presuppose a highlighted place to the transmitter regarding the receiver), places the public as the interlocutor and even as the message co-author. The aim of this work is to show that the UHUU Centre focus on works such as researches and productions in partnership with the Marcio Pizarro and the processes-researches-actions in partnership with the Interarts CNPq Research Group: interartistic processes and systems and performance studies.

Formação continuada de professores como um projeto coletivo e de identidade profissional

This research is part of the field of teacher training, especially developed the topic of continuing education. There is, according to the literature, the importance of this training for teachers as a sort of continuum, trajectory in which the teacher will (re) building their knowledge throughout their lives, in order to provide knowledge and values that add to your practice teaching. However, often the training activities are designed for knowledge transmitter model forming agent for the teacher, disregarding the different contexts of school communities, this strategy which hardly reaches the real needs of teachers in their daily lives. It is evident, too, the need to provide, in training moments, spaces to engage in dialogue and reflect on the teachers profession today, (re) building thus their teacher identity. In this context, the objective of this research is to examine whether the continued formation is configured as a collective construction and as a space for reflection on what it means to be a teacher. The research is characterized by a qualitative approach, and to collect data, we used the semi-structured interview technique. Participants were five teachers in the areas of Physical Education, History, English, Portuguese and Mathematics, a state school Treble city education (SP). The results show the importance of continuing education for teachers, which provides reflections, discussions, acquisition of knowledge and skills that contribute to its performance, motivating and developing strategies to enable them to face the challenges of everyday life and reflect collectively on what it means to be a teacher. It was concluded that continuing education for this group of teachers is configured as a space for collective construction, which together with other teachers rethink, reflect and continuously reconstruct their practices and objectives, and enables reflection on the teaching profession constantly. It will be essential, therefore...
