Antimicrobial activity of natural products against Helicobacter pylori: a review

Throughout the genetic and physiological evolution of microorganisms, the microbiological sciences have been expanding the introduction of new therapeutic trials against microbial diseases. Special attention has been paid to the bacterium Helicobacter pylori, which induces gastric infections capable of causing damage, ranging from acute and chronic gastritis to the development of gastric cancer and death. The use of compounds with natural origins has gained popularity in scientific research focused on drug innovation against H. pylori because of their broad flexibility and low toxicity. The aim of this study was to describe the use of natural products against H. pylori in order to clarify important parameters for related fields. The study demonstrated the vast therapeutic possibilities for compounds originating from natural sources and revealed the need for innovations from future investigations to expand the therapeutic arsenal in the fight against H. pylori infection.

Biotecnologias aplicadas à reprodução de éguas velhas

The acceptance of biotechnology for the most equine breeders association had a significant effect in the horse industry, gaining popularity around the world, because the increasing on the genetic gain, allowing the use of sub fertile mares and stallions with high genetics value on reproduction. The embryos in vitro production of human and cattle has been used with success, however in vitro embryo production is not efficient in the horse, as oocyte transfer (OT) and intracytoplasmatic sperm injection (ICSI). The oocyte transfer has been used especially in subfertile old mares presenting reproductive pathologies as: endometrite, cervical and uterine adhesions, blocked oviduct, perineal laceration and ovulation failures. During oocyte recovery process, the oocytes must be collected from immature follicles that need be matured in vitro or in vivo matured oocytes from pre-ovulatory follicles through the transvaginal aspiration guided by ultrasound. The recovered oocyte is transferred to a previously inseminated recipient mare, through the flank laparotomy. The intracytoplasmatic sperm injection (ICSI) is a procedure of in vitro fertilization that needs only one sperm that is aspirated and injected inside the oocyte. The oocytes used, can be from mature and immature follicles. Fresh, cooled and frozen semen can be used, because the procedure not requires a functional sperm. The use of Piezo drill resulted in a breakthrough the pellucid zone, allowing the vibration per minute provided in the sperm injection pipette, a major result of cleaved oocytes, due to a better sperm injection in the oocyte. The embryo transfer can be straight inside the oviduct, as also transcervical transferred after embryo culture produced in vitro. In conclusion both procedures (OT and ICSI) are effective to be used on equine assisted reproduction, getting results even lower than expected, but satisfactory from animal genetically superior

Atividades circenses em academias: uma nova opção no âmbito do lazer

The Brazilian population needs of practicing exercises increases every day by the health or pleasure results of it. But although conventional options of physical activities are more popular and easier to find out wherever you go, alternative ways of exercising yourself and unconscious and indirect ways to obtain wellness and health are increasing its popularity nowadays. One example of it is the circus classes inside the gyms, where people have fun during intense body working, while get in shape and relax them mind, getting all the benefits like any other conventional physical activity does. Thinking about the increasing teaching of circus arts like a new option of physical activity and leisure to the Sao Paulo citizens inside its bigger gyms, this study founded out how and why these classes were offered there and the reasons of the people interests and maintenance of them practice in this kind of classes.

A manifestação das diferentes modalidades no emprego do verbo auxiliar poder em português e em espanhol: análise do discurso de autoajuda

This paper aims to investigate the behavior of the modal verb poder as an auxiliary verb in text written in both two Romance languages, Brazilian Portuguese and Iberian Spanish. This research follows a functionalist language approach, more precisely the Dutch Functional Grammar tradition, based on the modality classification proposed by Hengeveld (2004). This author considers two main criteria: target of evaluation, and semantic domain of evaluation. Considering this classification, we analyze the use of the auxiliary verb poder in a corpus of self-help discourses, which currently enjoy enormous popularity in various parts of the world. Although in Portuguese the auxiliary verb poder is essentially an epistemic modal (cf. Neves 1999-2000) —which, according to the Hengeveld (2004), corresponds to the event-oriented epistemic modality—. However, our analysis show that, given the essentially optimistic nature of the discourse analyzed, the self-help discourse, the previously mentioned modal verb (poder) behaves predominantly as a participant-oriented facultative modal. This result demonstrates the importance of considering the context of occurrence of the verb poder in order to evaluate the effects of meaning associated with its use.

O estilo do rei: o diálogo entre O Rei Leão, da Disney, e Hamlet, de Shakespeare, sob uma perspectiva semiótica

This work consists of a semiotic analysis of the animation motion picture The Lion King (1994), by the Walt Disney Animation Studios, describing its intertextual relation with Hamlet, by Shakespeare, considering Disney’s individuality, its style. In order to study style in texts, we use discursive semiotics theory, highlighting Discini’s work (2013) and the concept of discursive settings. Hence, a deep discussion about The Lion King’s style, compared to the Shakespeare’s play, is established. The movie, once a syncretic text, requires advanced studies on Expression Plane, its plastic, musical and verbal/phonic aspects. We find these studies in the work of José Luiz Fiorin (2009), Lúcia Teixeira (2009), Ana Claúdia de Oliveira (2009), Jean-Marie Floch (2009) and Antônio Vicente Pietroforte (2008). We note how a syncretic text makes the discursive settings more complex by assembling plastic and sonorous materials in semissimbolic relation. Once defined The Lion King’s style, we analyze the way it justifies the intense popularity of this kind of animation features. Finally, it is important to understand how Disney uses in its style not only discursive settings, but also passional settings, revealing its own way to stir emotions on the spectator

A educação de adultos como socialização: Hannah Arendt versus Paulo Freire

This paper analyzes data under diametrically opposed theoretical frameworks. Encouraged by the sudden and recent popularity of Hannah Arendt, we decided to submit the data of a already presented dissertation to a “new” reference, extracted from Arendt’s famous text on the education crisis in the United States in the 1950. Data had been interpreted in the light of Paulo Freire’s epistemology. In further analyzes, from Arendt, our interpretations gained even more strength. However, in the final comparison between the two thinkers stand out irreconcilable differences: For Arendt, it is impossible to educate adults and the world of education should be detached from the world of politics, since the responsibility of the educator is based on tradition and authority while for Freire is indeed possible to educate adults and the responsibility of the educator – as in Sartre – leads to freedom. Our conclusion is to be possible the social education of adults if we educate ourselves with them in a dialogic relationship.

Correlation between pH and surface structural changes on human enamel submitted to different tooth whitening agents

The intense valuation of an esthetic pleasant smile guided the dentistry to bleached tooth due the popularity of whitening treatments. The consequence of it is an increasing interest in searching the effect of peroxides in hard dental tissues. The aim of this work was to analyze qualitatively in vitro the human enamel after three different bleaching treatments: Opalescence PF 10%, White Class 7.5% and Opalescence Xtra Boost 38%, correlating the structural changes in the surface of the enamel with its respective pH. A total of 40 sound human pre-molars were randomly divided into four groups of 10 elements, which had been immersed in artificial saliva during all the experiment. Bleaching protocols followed the recommendations of the respective manufacturers. Each bleached sample and control group were submitted to a scanning electronic microscopy analysis and compared with one another. Bleaching agents used in this experiment had modified the morphologic aspect of the surface of the dental enamel; however, it did not have correlation between the degrees of severity of the alterations and pH. There is a correlation between hydrogen peroxide concentration and changes in the enamel, where G4 showed more severe alterations, followed for G3 and G2.

Protocolo radiográfico para a instalação de mini-implantes: descrição da técnica

In the last decade mini-screws have gained popularity in orthodontics field and a correct placement of mini-screws is a critical point to the success of the skeletal anchorage. A careful clinical and radiographic diagnostic before insertion mini-screw is an essential requirement to achieve the central point of the radicular septum. The correct application of these pre-surgical procedures should avoid possible iatrogenic damages in periodontal ligament, dental roots, nasomaxillary cavities, or even important vascular tissues. As of today, periapical radiographs is a regular pre surgical procedure during mini-screw insertion technique. Nevertheless, accurate execution of the radiographic parallax technique can offer to us useful and precise radiographic images, to decide the right local insertion of mini-screws in to the septum bone. The purpose of this paper is to describe the ¬application of new positioning circular guides in conjunction with a ¬parallax radiographic protocol before placement of orthodontic mini-screws.
