Juventude, drogas e biopolítica

In this article, we tackle the issue of youth and drugs as something linked to biopower and biopolitics, both concepts developed by Michael Foucault. Youth and drugs are taken and analyzed in situations involving the management of crime linked to the risks and deviations from the law, abuse and dependence. The youth; irreverent, courageous, healthy, idealistic, and that wanted to change the world for the better as we have seen in the past, is now strongly related to violence, dangerous activities, moral and social risks, drug addiction, criminality, and others negative images. To deal with these young people, tolerance and small punishments of yore are not enough anymore. The young people emerge as a segment of the population subject to various actions and programs. The drugs now are seen as matters of security and public health. There is a shifting and repositioning in the discourse about the young - from minor, drugged, and criminal to lawbreaker, user and drug addict. The change is subtle, but represents a modulation in the devices of social control. Beyond the consent of the young to get rid of drugs, there is a search for the creation of a wide area of monitoring of their behavior through the activation of community protection networks. The belief that the young are more impressionable and vulnerable, and that action on the cause of the problem or risk reduction are the most efficient ways of management, taking responsibility away from personal and family sphere and transferring it to the State, contributes to the increasing control of young people nowadays.

A psicopatologização da infância no contemporâneo: um estudo sobre a expansão do diagnóstico de transtorno de déficit de atenção e hiperatividade

The expansion of psychiatric labeling does not reach only the adult population, but also the problematic related to childhood have been captured by the speeches and practices of the medical-psychiatric knowledge and turned into psychopathologies which tend to be treated with the main resource made available by psychiatrics in the present times: the psychotropic drugs. This work presents a critical thinking on the expansion of the diagnoses of “attention deficit disorder and hyperactivity” (ADHD) both in children and teenagers and on the conduction of drug therapies. It follows that the processes of childhood psycho-pathologization and the trivializing of psychotropic drug prescription are related to the overvaluation of the biological conception of psychic suffering and to the economic interests of the great pharmaceutical laboratories which by means of several strategies influence the medical practices, factors that lead to exposure of these patients to possible side effects and the risks of stigmatization that must be considered.

O mito de don juan e a subjetividade moderna

The legendary Don Juan character inhabits the popular imaginary with such a vibrancy of a myth, despite its slight recognition as such by the scientific literature. The purpose of this article is to verify if Don Juan’s play can be understood, scientifically, as a modern myth, as well as understand its mythical nature and its relation to the modern man. A structural and historical analysis of the two first plays on Don Juan has guided us: the one written by Tirso de Molina in 1630, and the one by Molière, written in 1665. The studies allow us to say that Don Juan is a typical modern myth, once it is constituted by narratives that expose a world looming under the signs of individualism, hedonism, arrogance and audacity forged under the appeals of sexual desire.

Tecnologias de gênero, masculinidades e apriosionamentos na execução penal

The study articulates the relations of power / knowledge in the production of crime and operationalization of the law, the subtle way in which technologies of gender naturalize actions and reactions in relationships, partnerships and daily struggles between staff and prisoners and the processes of subjectivity in contemporaneity . This study has as epistemological matrix the genealogy proposed by Michel Foucault, who has allowed diverse pathways as document reviews, semi-structured interviews, performance groups and courses. The interweaving of the forces and discourses has engendered the impact of technologies on gender, especially masculinity, in the present relations between staff and prisoners. The impact of this relationship puts on display the modulations of subjectivity in a continuum of oscillation between normalizing and singularizing modes of subjectification.

O princípio da integralidade no Sistema Único de Saúde (SUS): utopia?

The Brazilian Federal Constitution promulgated in 1988 created the concept of Social Welfare, which is based on the triad: Health, Social Security and Social Assistance. The Unified Health System (SUS) was then instituted. SUS is a conquest of a society that seeks social justice, integrality, equalitarian and universal access to health services. In the present essay, I succinctly discourse on the various meanings of integrality. I present the theoretical basis of complexity and transdisciplinarity by opposing to reductionism, aiming at showing that, by means of transdisciplinarity and intersectoriality, integrality can be achievable.

The SB-index and the HSB-index: efficient indices for spatial data warehouses

Spatial data warehouses (SDWs) allow for spatial analysis together with analytical multidimensional queries over huge volumes of data. The challenge is to retrieve data related to ad hoc spatial query windows according to spatial predicates, avoiding the high cost of joining large tables. Therefore, mechanisms to provide efficient query processing over SDWs are essential. In this paper, we propose two efficient indices for SDW: the SB-index and the HSB-index. The proposed indices share the following characteristics. They enable multidimensional queries with spatial predicate for SDW and also support predefined spatial hierarchies. Furthermore, they compute the spatial predicate and transform it into a conventional one, which can be evaluated together with other conventional predicates by accessing a star-join Bitmap index. While the SB-index has a sequential data structure, the HSB-index uses a hierarchical data structure to enable spatial objects clustering and a specialized buffer-pool to decrease the number of disk accesses. The advantages of the SB-index and the HSB-index over the DBMS resources for SDW indexing (i.e. star-join computation and materialized views) were investigated through performance tests, which issued roll-up operations extended with containment and intersection range queries. The performance results showed that improvements ranged from 68% up to 99% over both the star-join computation and the materialized view. Furthermore, the proposed indices proved to be very compact, adding only less than 1% to the storage requirements. Therefore, both the SB-index and the HSB-index are excellent choices for SDW indexing. Choosing between the SB-index and the HSB-index mainly depends on the query selectivity of spatial predicates. While low query selectivity benefits the HSB-index, the SB-index provides better performance for higher query selectivity.

Studi ed approfondimenti sulla composizione in acidi grassi del latte bovino di razza Reggiana con diverso fenotipo per k-caseina e Beta-lactoglobulina

The aim of the present study was to examine the association between milk protein polymorphism and fatty acids profiles of bovine milk. Milk samples were collected from each of 55 Reggiana cows during early, mid and late lactation, respectively, in two farms within the production area of Parmigiano Reggiano cheese. Identification and quantification of fatty acids were performed by gas chromatography. Milk fatty acid composition using cows of differing κ-casein (κ-Cn) and β-lactoglobulin (β-Lg) phenotypes was investigated. Statistically significant results regarding the associations between milk fatty acid composition and κ-Cn phenotype were found, in particular, κ-Cn BB seems to influence de novo fatty acid synthesis in the mammary gland. Also κ-Cn AB seems to have the same effect. Proportions of C10:0 (2,29a AA; 2,53b AB; 2,59b BB), C12:0 (2,77a AA; 3,17b AB; 3,20b BB) and C14:0 (9,22a AA; 10,25b AB; 10,27b BB) were higher in the milk from cows with κ-Cn phenotype AB and BB vs κ-Cn phenotype AA (p<0,05). Conversely C18:0 (7,84b AA; 7,20a,b AB; 6,94a BB) and C18:1 (19,19b AA; 16,81a AB; 16,79a BB) were lower in the milk from cows with κ-Cn phenotype AB and BB vs κ-Cn phenotype AA. The association between milk fatty acid composition and β-Lg phenotype was not statistically significant, except for some fatty acids. In particular, C12:0 (3,05a AA; 3,04a AB; 3,33b BB) was higher in the milk from cows with β-Lg phenotype BB vs β-Lg phenotype AA and AB (p<0,05). Concentrations of C18:0 (6,93a AA; 7,86b AB; 6,59a BB) and C18:1 (16,74a,b AA; 18,24b AB; 16,07a BB) were lower in the milk from cows with β-Lg phenotype AA and BB vs β-Lg phenotype AB (p<0,05). Moreover this research, carried out in farms within the Parmigiano Reggiano cheese district, analysed also the size distribution of fat globules in bulk milk of Reggiana and Frisona breed cows. In particular, the size distribution of individual milk fat globules of Reggiana cows with differing κ-Cn phenotypes was considered. From first observations, no statistically significant differences were observed.

Alimenti Funzionali e Componenti Nutraceutici come Biomodulatori

Recent knowledge supports the hypothesis that, beyond meeting nutrition needs, diet may modulate various functions in the body and play beneficial roles in some diseases. Research on functional foods is addressing the physiologic effects and health benefits of foods and food components, with the aim of authorizing specific health claims. The recognition that oxidative stress plays a major role in the pathophysiology of cardiac disorders has led to extensive investigations of the protective effects of exogenous antioxidants, but results are controversial. A promising strategy for protecting cardiac cells against oxidative damage may be through the induction of endogenous phase 2 enzymes with the enhancement of cellular antioxidant capacity. Sulforaphane (SF), a naturally occurring isothiocyanate abundant in Cruciferous vegetables, has gained attention as a potential chemopreventive compound thanks to its ability to induce several classes of genes implicated in reactive oxygen species (ROS) and electrophiles detoxification. Antioxidant responsive element (ARE)-mediated gene induction is a pivotal mechanism of cellular defence against the toxicity of electrophiles and ROS. The transcription factor NF-E2-related factor-2 (Nrf2), is essential for the up-regulation of these genes. We investigated whether SF could exert cardioprotective effects against oxidative stress and elucidated the mechanisms underpinning these effects. Accordingly, using cultured rat neonatal cardiomyocytes as a model system, we evaluated the time-dependent induction of gene transcription, the corresponding protein expression and activity of various antioxidant and phase 2 enzymes (catalase, superoxide dismutase, glutathione and related enzymes glutathione reductase, glutathione peroxidase and glutathione S-transferase, NAD(P)H: quinone oxidoreductase 1 and thioredoxine reductase) elicited by SF. The results were correlated to intracellular ROS production and cell viability after oxidative stress generated by H2O2, and confirmed the ability of SF to exert cytoprotective effects acting as an indirect antioxidant. Furthermore, to get better insight into SF mechanism of action, we investigated the effect of SF treatment on Nrf2 and the upstream signalling pathways MAPK ERK1/2 and PI3K/Akt, known to mediate a pro survival signal in the heart. The use of specific inhibitors of ERK1/2 and Akt phosphorylation demonstrated their involvement in phase 2 enzymes induction. The concentration of SF tested in this study is comparable to peak plasma concentration achieved after dietary exposure giving clear relevance to our data to support dietary intake of Cruciferous vegetables in cytoprotection against oxidative stress, a common determinant of many cardiovascular diseases.
