Marchetto Patrícia BorbaNa sociedade contemporânea, além da esfera pública de poder, possuímos uma esfera privada de poder, na qual se encontra grandes empresas multinacionais. Esses novos “detentores do Poder” são particulares, grupos ou pessoas, que se tornaram de certa forma desproporcionais socialmente em relação ao restante da sociedade. Neste patamar se encontram as grandes indústrias farmacêuticas, as quais além de possuírem uma função de suma importância para a sociedade mundial concentram grande poder econômico, social e até mesmo político. Desta forma, observa-se a existência de uma responsabilidade social das indústrias farmacêuticas vinculada com a necessidade de respeitar certas diretrizes incluídas na temática da bioética, já que trabalham com a ciência estritamente relacionada com a saúde e a vida da pessoa humana, e dos Direitos Humanos em geral. No entanto, tais indústrias por vezes acabam praticando ações que desrespeitam tais preceitos, como a realização de pesquisas científicas com seres humanos sem respeito as normas que tutelam a matéria e gerando verdadeira lesão aos Direitos Humanos, causando um verdadeiro terror científico. Esta relação tirana de poder que as grandes indústrias farmacêuticas impõe perante a sociedade deve ser tutelada pelo Direito Penal, sobretudo, para além dos limites dos Estados em que ocorrem as condutas, buscando uma tutela penal internacional. Desta forma, o presente trabalho pretende demonstrar a importância da existência de uma tutela internacional, com a possível utilização do Tribunal Penal Internacional e o enquadramento de tais condutas como crimes contra a Humanidade.

The reflex of social and cultural changes in discursive practices can indicate that language has a fundamental role in transforming the society and attempts of defining the directions of changes must include new forms of language practices. One of these forms concerns to computer media in teaching-learning process, showing how technology and culture interact in a significant way to interfere in language uses. In this context, it has been developed in UNESP/Assis linked to the Center for Language and Teacher Development the project Teletandem Brasil: Foreign Languages for All as a new practice of language teachinglearning through technological resources. The present paper aims to present a description of the teletandem sessions as a discursive gender according to the Bakhtin’s gender theory. The data was collected during the second semester of 2010, in sessions of interaction with an American university. The considerations are directed by the following questions: (a) how are the statements of a session discursively organized; (b) what kind of relationship the partners have with their mother language when they teach it as a foreign language, in this context. The analysis allowed us to conclude that: (a) the sessions can characterize a hybrid and secondary gender in this specific area of human activity, even the partners still find difficulties in this gender domain; (b) the teletandem sessions constitute an important instrument for the critical language awareness between the partners.

It is well known that breathing introduces rhythmical oscillations in the heart rate and arterial pressure levels. Sympathetic oscillations coupled to the respiratory activity have been suggested as an important homeostatic mechanism optimizing tissue perfusion and blood gas uptake/delivery. This respiratory-sympathetic coupling is strengthened in conditions of blood gas challenges (hypoxia and hypercapnia) as a result of the synchronized activation of brainstem respiratory and sympathetic neurons, culminating with the emergence of entrained cardiovascular and respiratory reflex responses. Studies have proposed that the ventrolateral region of the medulla oblongata is a major site of synaptic interaction between respiratory and sympathetic neurons. However, other brainstem regions also play a relevant role in the patterning of respiratory and sympathetic motor outputs. Recent findings suggest that the neurons of the nucleus of the solitary tract (NTS), in the dorsal medulla, are essential for the processing and coordination of respiratory and sympathetic responses to hypoxia. The NTS is the first synaptic station of the cardiorespiratory afferent inputs, including peripheral chemoreceptors, baroreceptors and pulmonary stretch receptors. The synaptic profile of the NTS neurons receiving the excitatory drive from afferent inputs is complex and involves distinct neurotransmitters, including glutamate, ATP and acetylcholine. In the present review we discuss the role of the NTS circuitry in coordinating sympathetic and respiratory reflex responses. We also analyze the neuroplasticity of NTS neurons and their contribution for the development of cardiorespiratory dysfunctions, as observed in neurogenic hypertension, obstructive sleep apnea and metabolic disorders.

Central mechanisms of coupling between respiratory and sympathetic systems are essential for the entrainment between the enhanced respiratory drive and sympathoexcitation in response to hypoxia. However, the brainstem nuclei and neuronal network involved in these respiratory-sympathetic interactions remain unclear. Here, we evaluated whether the increase in expiratory activity and expiratory-modulated sympathoexcitation produced by the peripheral chemoreflex activation involves the retrotrapezoid nucleus/parafacial respiratory region (RTN/pFRG). Using decerebrated arterially perfused in situ rat preparations (60–80 g), we recorded the activities of thoracic sympathetic (tSN), phrenic (PN), and abdominal nerves (AbN) as well as the extracellular activity of RTN/pFRG expiratory neurons, and reflex responses to chemoreflex activation were evaluated before and after inactivation of the RTN/pFRG region with muscimol (1 mM). In the RTN/pFRG, we identified late-expiratory (late-E) neurons (n = 5) that were silent at resting but fired coincidently with the emergence of late-E bursts in AbN after peripheral chemoreceptor activation. Bilateral muscimol microinjections into the RTN/pFRG region (n = 6) significantly reduced basal PN frequency, mean AbN activity, and the amplitude of respiratory modulation of tSN (P < 0.05). With respect to peripheral chemoreflex responses, muscimol microinjections in the RTN/pFRG enhanced the PN inspiratory response, abolished the evoked late-E activity of AbN, but did not alter either the magnitude or pattern of the tSN reflex response. These findings indicate that the RTN/pFRG region is critically involved in the processing of the active expiratory response but not of the expiratory-modulated sympathetic response to peripheral chemoreflex activation of rat in situ preparations.

The objective of this work is to present an analysis of the results of a study about the reading practices of a group of teachers from the public school, discussing how these practices constitute themselves since the initial formation until the teaching period. The selected teachers had their formation between the end of the 60’s and the beginning of the 80’s, remaining as teachers of the public school for the next twenty years. Using as methodology the narrative research, we are going to discuss how the reading appears in the lives of these professionals, what their representations about it are and how the reading permeates their lives and their actuations in the school, passing through the first contacts with the books until the collision between theory and practice, observed in the speech of the teachers who were interviewed, always taking into account the teaching formation.

Traumatic injuries to the vertebral column, spinal cord, and cauda equina nerve roots occur frequently in human and veterinary medicine and lead to devastating consequences. Complications include partial or complete loss of motor, sensory, and visceral functions, which are among the main causes of euthanasia in dogs. The present case report describes neurological functional recovery in two dogs that were treated surgically for severe spinal fracture and vertebral luxation. In the first case, a stray, mixed breed puppy was diagnosed with thoracolumbar syndrome and Schiff-Scherrington posture, as well as a T13 caudal epiphyseal fracture with 100% luxation between vertebrae T13 and L1; despite these injuries, the animal did show deep pain sensation in the pelvic limbs. Decompression through hemilaminectomy and spinal stabilization with vertebral body pins and bone cement were performed, and the treatment was supplemented with physiotherapy and acupuncture. In the second case, a mixed breed dog was diagnosed with a vertebral fracture and severe luxation between L6 and L7 after a vehicular trauma, but maintained nociception and perineal reflex. Surgical stabilization of the spine was performed using a modified dorsal segmental fixation technique Both patients showed significant recovery of neurological function. Complete luxation of the spinal canal observed radiographically does not mean a poor prognosis, and in some cases, motor, sensory, and visceral functions all have the potential for recovery. In the first case the determining factor for good prognosis was the presence of deep pain perception, and in the second case the prognosis was determined by the presence of sensitivity and anal sphincter tone during the initial neurological examination.

Twenty-four bitches which had been in labour for less than 12 hours were randomly divided into four groups of six. They all received 0(.)5 mg/kg of chlorpromazine intravenously as premedication, followed 15 minutes later by either 8 mg/kg of thiopentone intravenously (group 1), 2 mg/kg of ketamine and 0-5 mg/kg of midazolam intravenously (group 2), 5 mg/kg of propofol intravenously (group 3), or 2(.)5 mg/kg of 2 per cent lidocaine with adrenaline and 0(.)625 mg/kg of 0(.)5 per cent bupivacaine with adrenaline epidurally (group 4). Except for group 4, the bitches were intubated and anaesthesia was maintained with enflurane. The puppies' heart and respiratory rates and their pain, sucking, anogenital, magnum and flexion reflexes were measured as they were removed from the uterus. The puppies' respiratory rate was higher after epidural anaesthesia. in general the puppies' neurological reflexes were most depressed after midazolam/ketamine, followed by thiopentone, propofol and epidural anaesthesia.

The pseudo-Class III can be defined as a functional reflex of an anterior positioning of the mandible, an acquired muscular position that simulates a mesiocclusion. The diagnosis and treatment plan of this condition must be based on a cephalometric evaluation that provides information about the relative contributions of the skeletal and dental components to the malocclusion. There is still great controversies about when is the best moment to start the Class III treatment. The purpose of this article is to describe a case report in which a Class III patient was successfully treated with reverse traction.
