We analysed the representations of science and of scientists at Jornal Nacional, the main Brazilian TV news. We carried out content and frames analysis, besides the lexical and semantic analysis of the transcriptions of the science and technology stories. Our results show a narrative that highlights the novelties and the epopee of the scientific advance, mainly in the health field. But to the emotional palette feelings of combat, anxiety and triumph were added. The face of the scientist presented by the TV news is mainly masculine, suggesting a stereotyped role of the male and female scientist: meanwhile men go out to literally explore other worlds, women take care of health and of the body.

Pseudomonas aeruginosa is a widely represented species of bacteria possessing of a pathogenic potential. This infectious agent is causing wound infections, fibrotic cystitis, fibrosing pneumonia, bacterial sepsis, etc. The microorganism is highly resistant to antiseptics, disinfectants, immune system responses of the body. The responses of a quorum sense of this kind of bacteria ensure the inclusion of many pathogenicity factors. The analysis of the scientific literature made it possible to formulate four questions concerning the role of biofilms for the adaptation of P. aeruginosa to adverse environmental factors: Is another person appears to be predominantly of a source an etiological agent or the source of P. aeruginosa infection in the environment? Does the formation of biofilms influence on the antibiotic resistance? How the antagonistic activity of microorganisms is realized in biofilm form? What is the main function of biofilms in the functioning of bacteria? A hypothesis has been put forward the effect of biofilms on the increase of antibiotic resistance of bacteria and, in particular, P. aeruginosa to be secondary in charcter. It is more likely a biofilmboth to fulfill the function of storing nutrients and provide topical competition in the face of food scarcity. In connection with the incompatibility of the molecular radii of most antibiotics and pores in biofilm, biofilm is doubtful to be capable of performing a barrier function for protecting against antibiotics. However, with respect to antibodies and immunocompetent cells, the barrier function is beyond doubt. The biofilm is more likely to fulfill the function of storing nutrients and providing topical competition in conditions of scarcity of food resources.

Studies on potential treatments of Coronavirus Disease 2019 (COVID-19) are important to improve the global situation in the face of the pandemic. This review proposes lithium as a potential drug to treat COVID-19. Our hypothesis states that lithium can suppress NOD-like receptor family pyrin domain containing-3 (NLRP3) inflammasome activity, inhibit cell death, and exhibit immunomodulation via membrane depolarization. Our hypothesis was formulated after finding consistent correlations between these actions and membrane depolarization induced by lithium. Eventually, lithium could serve to mitigate the NLRP3-mediated cytokine storm, which is allegedly reported to be the inciting event of a series of retrogressive events associated with mortality from COVID-19. It could also inhibit cell death and modulate the immune system to attenuate its release, clear the virus from the body, and interrupt the cycle of immune-system dysregulation. Therefore, these effects are presumed to improve the morbidity and mortality of COVID-19 patients. As the numbers of COVID-19 cases and deaths continue to rise exponentially without a clear consensus on potential therapeutic agents, urgent conduction of preclinical and clinical studies to prove the efficacy and safety of lithium is reasonable.

Technology, body and physical education: between training and teaching practiceAbstractThis essay aims to reflect the relationship between training in Physical Education, the body in movement and technologies in school education. We understand that Physical Education needs to understand this body and its different nuances in the face of technologies, which can contribute as auxiliary tools in the emancipation process of human beings in order to become more reflective, critical and creative. With advances in technologies, we observe rapid changes in society, and the same with the body. It is necessary to debate the interrelationships that occur in society between technology, body and education as a historical and continuous process of transformations involving cultural, economic, political, social issues that have (re)configured the role of the Physical Education teacher with “new” knowledge and skills in the school environment.Keywords: Physical Education.

This article follows an aspect of Spenser’s structure of the The Faerie Queene, namely that of duality, to discuss how the notion of the body is treated. This representation gives way to doubleness, if not to say problematic expression of bipolarity, someties as both male and female figures, in the process of “sexual” regeneration or creation. The article, thus, mostly highlights the role of Britomart, the heroine of Book III, and Artegall, hero of Book V, as the one is presented in an armour, brandishing a “phallic” lance, and the other is introduced in a woman’s attire. In both of them, therefore, one finds the principle of the duality of bodily representation, or as Pico della Mirandola has it, that the male and female representation can be seen as “two powers in the same substance.”

Abstract“Semioethics” is a neologism coined in the early 1980s to highlight the relation between signs and values, identity and otherness. It keeps account of Victoria Welby’s concept of “significs” and of Sebeok’s “global semiotics” with its critique of glottocentric and anthropocentric tendencies. Together both sources, significs and global semiotics, provide the context for contributions from semioethics to education. Semioethics recovers the ancient vocation of semiotics, originally “semeiotics,” for life and its wellbeing. It elicits the importance of applying an interdisciplinary approach and a “detotalizing method” in education by contrast to the totalizing approaches of grand narratives. The human being is endowed with a “primary modeling device,” also called “language,” and with it “syntactics.” Semioethics considers the role of these special characteristics that specify the human being as a human being, a “semiotic animal,” and addresses the human propensity for creativity, critique, and responsibility for health over the globe, both in terms of physical-organic materiality, the body, and of semiotic materiality, signs and values. These characteristics can be developed and enhanced through a specifically “linguistic education” with a particular emphasis on otherness, dialogue, and listening. Practicing semioethics becomes more pressing in the face of the relational dynamics between the historical-social and biological spheres, between culture and nature, between semiosphere and biosphere, and between semiotics, biosemiotics, and education.

The entire human body is generally affected by exercise. Exercise affects the physiology of every system leading to various changes which generally affect the health of the body. Malaria on the other hand is one of the diseases with the most mortality rates especially in Nigeria and Africa, killing millions every year. As lethal as malaria is, no vaccine has been produced for it. Other preventive measures that improve individual’s natural immunity against attacks are still the most effective ways of tackling the disease in the face of failing Artemisinin Combination Therapy (ACT) approved by the World Health Organisation (WHO) to manage patients attacked by the disease. This study examines the role of regular exercise on malaria occurrence among selected male and females. It was to determine whether or not regular exercise reduces the frequency of malaria occurrence? Sixty (60) healthy subjects were selected and divided into two equal groups of regularly exercising subjects and nonexercising subjects with each group consisting of an equal number of male and female subjects. The study was for a period of twelve (12) weeks with the subjects checked every two weeks to see if there was an incidence of malaria. The subjects then filled a questionnaire to ascertain other factors like duration of exercise. At the end of the study period, the non-exercising group showed a higher frequency of malaria attack in both the male and female subjects compared to their regularly exercising counterparts; the non-exercising female subjects had a mean frequency of malaria occurrence of 1.2 compared to 0.4 for the regularly exercising subjects, while the non-exercising male subjects had a mean frequency of malaria occurrence of 0.7 compared to 0.3 of the regularly exercising male subjects. The study showed that regular exercise reduces the frequency of malaria occurrence in individuals.

The article examines the role of value conglomerate currents in sections of willing machines inthe philosophy of G. Deleuze and F. Guattari. The movement and current of value conglomeratesthrough the person turned away from God is refined and formed. Accordingly, the essence of theconcepts introduced by the philosophers of the «wanting machine» and «body without organs»is clarified. It is noted that the specificity of the terminological apparatus of the collaborationof philosophers is built on the defined ontological plane of diversity and the dichotomouscontradiction of mental and schizoid judgments, where meaning loses the usual forms of logicand is replaced by singularities. The dichotomy of singularities was developed by G. Deleuzein the treatise «The Logic of Meaning», during the study of planes of meaning in the worksof L. Carroll. It is established that the desiring machine becomes the presentation of the basiccomponent of the person - as an organism, mental thinking and unconscious consumption. Havingthe constituent organs of activity, a person is unconsciously formed into a willing machine, thatis, a person moves at will, which is modeled in his instructions for using his own organism. It isnoted that the machine that desires is not just a symbiosis of spare parts, which can be noticed inthe philosophy of G. Deleuze and F. Guattari in the first place, but is a machine that constantlydesires, even when something sucks in itself. Desire pushes the machine to interconnect withother machines, so it becomes a slave of its own desires, and the range of these desires expandsand then narrows like a pendulum oscillation. The desires themselves are irresistible, so someof them are controlled by capitalism and psychiatry through the structure of a society of control,digitization and detritorialization. It is the machines that desire to do everything by the body, butit causes the body to suffer, because the body is already a concept of docking, levers, standards ofconnection, moral regulators of the superconscious. It is determined that the body without organscomes into conflict with the wanting machine, because the body searches for the cause of sufferingin the presence of organs, and therefore removes them, becomes sterile. However, philosopherspoint to the constant repetition of motions not only of the desiring machine, but also of the bodywithout organs: decipherment returns to digitization, the body being filled by the organs of desire.The processes of constant return are deteritized by capitalism. Value conglomerates themselvescombine into the horrible twin of God and the devil, good and evil. The minority replaces themajority. An example of the metamorphosis of a minority homosexual into the majority of LGBTpeople is given. It is stated that the most valuable conglomerates are embedded in the ontologicalmetamorphosis, not in the dualism of the pairs of good and evil. The values themselves are definedas the lines of cutting a person through the pendulum movements of the jacket of good and evil,and therefore, as such, they are not internal to the wanting machine. The model of movement ofthe flows of value conglomerates, which is represented as a continuous cutting of the lines of thegood and evil desires of passive thinking machines, driven into the judgment of the social systemby the method of psychoanalytic compulsion, is defined. In this model, the face of God is alwaysturned away from man, and the desire of man crosses God as if sewing him to his own judgment.

While most studies on person recognition examine the face alone, recent studies have shown evidence for the contribution of the body and gait to person recognition beyond the face. Nevertheless, little is known on whether person recognition can be performed based on the body alone. In this study, we examined two sources of information that may enhance body-based person recognition: body motion and whole person context. Body motion has been shown to contribute to person recognition especially when facial information is unclear. Additionally, generating whole person context, by attaching faceless heads to bodies, has been shown to activate face processing mechanisms and may therefore enhance body-based person recognition. To assess body-based person recognition, participants performed a sequential matching task in which they studied a video of a person walking followed by a headless image of the same or different identity. The role of body motion was examined by comparing recognition from dynamic vs. static headless bodies. The role of whole person context was examined by comparing bodies with and without faceless heads. Our findings show that body motion contributed to body-based person recognition, and person recognition from the body alone was better in dynamic vs. static displays. In addition, whole person context contributed to body-based person recognition when recognition was performed in static displays. Overall these findings show that recognizing people based on their body alone is challenging but can be performed under certain circumstances that enhance the processing of the body when seeing the whole person.

Acne vulgaris  is a common chronic disease involving blockage and /or inflammation of pilo sebaceous units.  The resulting appearance can lead to anxiety, reduced self-esteem, and in extreme cases depression. It is the commonest dilemma associated with complexion and smoothness of skin .sometimes leading to major skin problems, which is characterized by macula, papulo, pustular eruption on the skin, especially on the face.  The role of diet and cigarette smoking in the condition is unclear and neither cleanliness nor exposure to sunlight appears to play a part. In both sexes, hormones called androgens appear to be part of the underlying mechanism, by causing increased production of sebum. In the Ayurvedic perspective Acne vulgaris  can be correlated with Mukhadushika . Mukhadushika is explained by Aacharya Sushruta under kshudra rogas and is considered as swatantra vyadhi in the ayurvedic literature. It is characterized by shalmali kantaka sadrusha pidika on the face. Mukhadushika is also called as Tarunya pitika. Tarunya pitika word itself says that it is pittikopatti in taurnya awastha due to some hormonal changes, up to limit it is normal but in excess, it becomes a reason for depression in a person. In Modern Era, physicians came across so many patients suffering from the disease, mukhadushika .The prevalence of mukhadushika increasing day by day due to their fast lifestyle, consumption of food, constipation,late-night sleep, fast food, cold drinks leads to an imbalance in doshas which in turn affects the body as well as mind.turns affects body as well as mind
