It has been demonstrated that, on abrupt withdrawal, patients with chronic exposure can experience a number of symptoms indicative of a dependent state. In clinical patients, the earliest to arise and most persistent signal of withdrawal from chronic benzodiazepine (Bzp) treatment is anxiety. In laboratory animals, anxiety-like effects following abrupt interruption of chronic Bzp treatment can also be reproduced. In fact, signs that oscillate from irritability to extreme fear behaviours and seizures have been described already. As anxiety remains one of the most important symptoms of Bzp withdrawal, in this study we evaluated the anxiety levels of rats withdrawn from diazepam. Also studied were the effects on the motor performance and preattentive sensory gating process of rats under diazepam chronic treatment and upon 48-h withdrawal on three animal models of anxiety, the elevated plus-maze (EPM), ultrasonic vocalizations (USV) and startle + prepulse inhibition tests. Data obtained showed an anxiolytic- and anxiogenic-like profile of the chronic intake of and withdrawal from diazepam regimen in the EPM test, 22-KHz USV and startle reflex. Diazepam chronic effects or its withdrawal were ineffective in promoting any alteration in the prepulse inhibition (PPI). However, an increase of PPI was achieved in both sucrose and diazepam pretreated rats on 48-h withdrawal, suggesting a procedural rather than a specific effect of withdrawal on sensory gating processes. It is also possible that the prepulse can function as a conditioned stimulus to informing the delivery of an aversive event, as the auditory startling-eliciting stimulus. All these findings are indicative of a sensitization of the neural substrates of aversion in diazepam withdrawn animals without concomitant changes on the processing of sensory information

Cataract is the leading cause of blindness in dogs. It is defined as an opacity in the lens and is independent of resulting visual deficit. Although there are a growing number of studies related to drug therapy of cataract, the treatment is still considered exclusively surgical. Among the techniques used to remove cataract, phacoemulsification is the best performer. Anesthesia in intraocular surgery has several peculiarities, which are essential to successfully conduct phacoemulsification in dogs. In these patients, a safe and effective anesthesia requires the maintenance of intraocular pressure close to normal, preventing the activation of the oculo-cardiac reflex and complete immobilization of the eye. The appropriate conditions for such surgical procedures can be established through the use of drugs from different pharmacological groups for premedication, induction and maintenance of anesthesia, making a balanced anesthesia. This work was compiled from a careful review of the literature on anesthesia in cataract surgery. Considerations on the pre-medication, induction and maintenance of anesthesia are discussed, aiming to contribute to the phacoemulsification becomes more safe and suitable for the anesthesiologist and the surgeon as well as comfortable for dogs undergoing surgery

The bee Apis mellifera has a great importance because it is the most economically valuable pollinator for crops worldwide, ensuring cross-pollination and increasing fruit yield. Moreover, agriculture increasingly develops chemicals to control weeds, fungi and insect pests to ensure productivity. Insecticides are used on a large scale in the state of São Paulo, in cultures of citrus for control of greening. Applications are usually made by aircraft and as a result of the effect derives a significant mortality is observed in apiaries near the plantations. Honey bees can get in contact with such chemical agent through their activities of water harvesting, plant resins, pollen and nectar. Intoxication resulting from this exposure can be lethal, which is easily detectable, or cause effects on the physiology and behavior of the insect. These, in turn are hardly detectable, such as paralysis, disorientation, behavioral changes, but can compromise the entire social structure of the colony, therefore aimed to study the effects of the insecticide Thiamethoxam behavior of honeybees A. mellifera. Newly emerged individuals and with 10 days of age were tested. Applications of 1 μL de Thiamethoxam, diluted in acetone, were made on the dorsal thorax with a microapplicator. Preliminarily, it was observed LD50 twenty four hours after topical treatment of Thiamethoxam. It was found that the LD50 for newly emerged honeybees is 8 ng/bee and for honeybees with 10 days of age is 18 ng/bee. The behaviors were analyzed 1 hour after application of insecticide at doses corresponding to LD50/100, LD50/50, LD50/10 and LD50, besides the control group. In the test reflex proboscis extension, there was impairment of behavior at doses of 8 and 18 ng/bee workers in newly emerged workers and 10 days of age, respectively. And in locomotor behavior was no change only at a dose of 18 ng/bee workers at 10 days of age... (Complete abstract click electronic access below)

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.
