A crença religiosa sob a perspectiva semiótica de Peirce

Current paper presents the relationships between beliefs, specifically religious ones, and the Peirce’s theory of interpretants. It is assumed that religious belief emphasizes the emotional aspect of faithful, preventing criticism and change of habit. According to the author, the nature of cognition is contrary to the determination of this kind of belief since it is based on the method and fallibility of hypotheses. It is not enough for the method to deduce its consequences but seeks the inductive verification of their results in the long run and through the community of beings who thinks through signs. The problem of religious belief is the acceptance of a transcendent world and intuition which guides behavior. The vague idea of God is not submitted to scientific hypotheses but, engendered by religious systems, it creates signs whose emotional appeal is evident, redirecting it to its own target principles. Therefore, is repeats the success achieved in the past by dogmas, which were effective to appease the anguish of the believer and reproduce order. Knowledge should not have any boundaries because it is grounded on the method and cognition of reality.

Concepções de síntese no estudo deleuzeano de Hume

In order to emphasize the leading role Hume plays in the work of Deleuze, especially in his philosophical production during the years 1950 and 1960, we will describe the main concepts of synthesis the French philosopher proposed in Empiricism and Subjectivity , in 1953. One of the questions that stimulate this research is the empirical origin of the self. Deleuze thinks this origin as being started by a sort of incomprehensible or empirical synthesis. Furthermore, we recognize the synthesis of time which describes the condition governing the operation of habit. There are at least two other concepts of syntheses in Deleuze s book dedicated to Hume. We find, on one hand, the synthesis indicating the agreement of the faculties or, to state it clearly, the agreement between the principles of association and of passion. On the other hand, we still find the syntheses of judgments arising from the correlation between the faculties.

Avaliação dos efeitos promovidos pela sibutramina, associada ou não à nicotina, nos tecidos reprodutivos de ratas albinas

Sibutramine is a drug recommended clinically for the treatment of obesity, but there are women that use the drug for maintenance of body weight. Many time this use occur associate to habit of tabagism, being the nicotine the main toxic compound in the cigarette. The goal of study was to evaluate the side effects promoted by sibutramine, associated or not to nicotine, in the reproductive tissue of adult female rats. Wistar animals (n =30), were distributed in the groups: a) Control A (0.3 mL of distilled water; oral); b) Sibutramine (15 mg/kg of body weight; oral); c) Control B (0.3 mL of saline solution; intraperitoneal); d) Nicotine (4.0 mg/kg of body weight; intraperitoneal); e) sibutramine + nicotine. The treatments were conducted during 30 consecutive days (single dose, daily). Sibutramine, associated or not to nicotine, affected the folliculogenesis and luteogenesis. There were significant alterations (p<0.05) in the thickness of uterine layers, considerate each treatment. In conclusion, the administration isolated of sibutramine or nicotine promoted deleterious effects in the reproductive tissues of female rats and these effects were potential in the group that received both drugs.

O único luxo de um santo laico: fotografias em biografias de Clóvis Beviláqua

The jurist Clovis Bevilaqua (1859-1944) was a privileged member of a political and intellectual elite in the context of the transition from the nineteenth to the early decades of the twentieth century in this country, having been a professor at the Faculdade de Direito de Recife, author of the Civil Code of 1917, consultant for the Ministério das Relações Exteriores and jurist of international prestige, and literary critic and author of law, philosophy and history.Their biographies emphasize the breadth of his legal knowledge, the merits of civil codification which was author and lifestyle humble and generous earning him the nickname "secular saint". However, the lawyer had the habit of collecting photos of himself and of his family and this behavior is characterized as a single vanity for his biographers. From four biographies of Clovis Bevilaqua, written by Lauro Romero (1956), Raimundo de Menezes and Ubaldino de Azevedo (1959), Noemia Paes Barreto Brandão (1989) and Silvio Meira (1990), we intend to discuss how these images are used to illustrate the trajectory of the jurist and corroborate the distinct narratives models.

Não preferência para alimentação e antibiose em cultivares de amendoim a Stegasta bosquella (Chambers) (Lepidoptera: Gelechiidae)

This work aimed to evaluate the attractiveness, non-preference for feeding and antibiosis in straight and runner growth habit peanut cultivars to Stegasta bosquella (Chambers). Eight cultivars were evaluated, four of straight growth habit (IAC Tatu, IAC 22, IAC 8112 and IAC 5) and four of runner growth habit (IAC Runner 886, IAC 147, IAC 125 and IAC 503). Free-choice and no-choice feeding tests were performed, using pairs of overlapped leaf discs with 1.0 cm diameter, which were placed in Petri dishes where third instar larvae of S. bosquella were released. The attractiveness to the larvae was assessed in predetermined times, in addition to the dry mass consumed. In the antibiosis assay, the biological parameters were evaluated: period and viability of larvae, pre-pupae, pupae, and total, weight of larvae and pupae, sex ratio and longevity. None of the runner growth habit cultivars exhibited non-preference for feeding-type resistance. Among the straight growth habit cultivars, IAC 5 and IAC 22 were the least attractive and consumed in the free-choice feeding test, and IAC 5 and IAC 8112 were the least attractive in the no-choice test. The runner growth habit cultivars IAC 147 and IAC Runner 886 affected the larval survival of S. bosquella, exhibiting antibiosis-type resistance. For the straight growth habit cultivars, IAC 22 and IAC 8112 affected the larval viability, presenting antibiosis-type resistance. The straight and runner growth habit cultivars did not influence the biological parameters of weight of pupae, sex ratio and longevity of S. bosquella.

Protease-inhibiting, molecular modeling and antimicrobial activities of extracts and constituents from Helichrysum foetidum and Helichrysum mechowianum (compositae)

Background Helichrysum species are used extensively for stress-related ailments and as dressings for wounds normally encountered in circumcision rites, bruises, cuts and sores. It has been reported that Helichysum species are used to relief abdominal pain, heart burn, cough, cold, wounds, female sterility, menstrual pain. Results From the extracts of Helichrysum foetidum (L.) Moench, six known compounds were isolated and identified. They were 7, 4′-dihydroxy-5-methoxy-flavanone (1), 6′-methoxy-2′,4, 4′-trihydroxychalcone (2), 6′-methoxy-2′,4-dihydroxychalcone -4′-O-β-D-glucoside (3), apigenin (4), apigenin-7-O-β-D-glucoside (5), kaur-16-en-18-oic acid (6) while two known compounds 3,5,7-trihydroxy-8-methoxyflavone (12), 4,5-dicaffeoyl quinic acid (13) together with a mixture of phytosterol were isolated from the methanol extract of Helichrysum mechowianum Klatt. All the compounds were characterized by spectroscopic and mass spectrometric methods, and by comparison with literature data. Both extracts and all the isolates were screened for the protease inhibition, antibacterial and antifungal activities. In addition, the phytochemical profiles of both species were investigated by ESI-MS experiments. Conclusions These results showed that the protease inhibition assay of H. foetidum could be mainly attributed to the constituents of flavonoids glycosides (3, 5) while the compound (13) from H. mechowianum contributes to the stomach protecting effects. In addition, among the antibacterial and antifungal activities of all the isolates, compound (6) was found to possess a potent inhibitor effect against the tested microorganisms. The heterogeneity of the genus is also reflected in its phytochemical diversity. The differential bioactivities and determined constituents support the traditional use of the species. Molecular modelling was carried out by computing selected descriptors related to drug absorption, distribution, metabolism, excretion and toxicity (ADMET).

Viscoelastic properties of bronchial mucus after respiratory physiotherapy in subjects with bronchiectasis

BACKGROUND: Previous studies have evaluated the effectiveness of postural drainage (PD), percussion (PERC), the coughing technique (CT), and other types of coughing in subjects with bronchiectasis. However, the application times of these techniques and the quality of the expectorated mucus require further study. The aim of our study was to evaluate the effectiveness of PD, percussion, CT, and huffing in subjects with bronchiectasis and assess the quantity and quality of bronchial mucus produced (measurement of wet and dry weight and determination of viscoelastic properties). METHODS: Twenty-two subjects with stable bronchiectasis (6 men; mean age: 51.5 y) underwent 4 d of experimental study (CT, PD+CT, PD+PERC+CT, and PD+huffing). The techniques were performed in 3 20-min periods separated by 10 min of rest. Before performing any technique (baseline) and after each period (30, 60, and 90 min), expectorated mucus was collected for analysis of viscoelasticity. RESULTS: A significant increase in the dry weight/wet weight ratio was found after 60 min of PD+PERC+CT (P = .01) and 90 min of PD+huffing (P = .03) and PD+PERC+CT (P = .007) in comparison with CT. PD+PERC+CT and PD+huffing led to the greatest removal of viscoelastic mucus at 60 min (P = .02 and P = .002, respectively) and continued to do so at 90 min (P = .02 and P = .01, respectively) in comparison with CT. An interaction effect was found, as all techniques led to a greater removal of elastic mucus in comparison with CT at 60 min (PD+CT, P = .001; PD+PERC+CT, P < .001; PD+huffing, P < .001), but only PD+PERC+CT and PD+huffing led to a greater removal of elastic mucus than CT at 90 min (P < .001 and P = .005, respectively). CONCLUSIONS: PD+PERC+CT and PD+huffing performed similarly regarding the removal of viscoelastic mucus in 2 and 3 20-min periods separated by 10 min of rest. PD+PERC+CT led to the greatest removal of mucus in the shortest period (2 20-min periods separated by 10 min of rest). (C) 2015 Daedalus Enterprises

Clinical and laboratory description of a series of cases of acute viral myositis

Describe the clinical and laboratory profile, follow-up, and outcome of a series of cases of acute viral myositis. A retrospective analysis of suspected cases under observation in the emergency department was performed, including outpatient follow-up with the recording of respiratory infection and musculoskeletal symptoms, measurement of muscle enzymes, creatine phosphokinase (CPK), lactate dehydrogenase (LDH), transaminases (AST and ALT), blood count, C-reactive protein, and erythrocyte sedimentation rate in the acute phase and during follow-up until normalization. Between 2000 and 2009, 42 suspected cases were identified and 35 (27 boys) were included. The median age was 7 years and the diagnosis was reported in 89% in the first emergency visit. The observed respiratory symptoms were cough (31%), rhinorrhea (23%), and fever (63%), with a mean duration of 4.3 days. Musculoskeletal symptoms were localized pain in the calves (80%), limited ambulation (57%), gait abnormality (40%), and muscle weakness in the lower limbs (71%), with a mean duration of 3.6 days. There was significant increase in CPK enzymes (5507±9180U/L), LDH (827±598U/L), and AST (199±245U/L), with a tendency to leukopenia (4590±1420) leukocytes/mm(3). The complete recovery of laboratory parameters was observed in 30 days (median), and laboratory and clinical recurrence was documented in one case after 10 months. Typical symptoms with increased muscle enzymes after diagnosis of influenza and self-limited course of the disease were the clues to the diagnosis. The increase in muscle enzymes indicate transient myotropic activity related to seasonal influenza, which should be considered, regardless of the viral identification, possibly associated with influenza virus or other respiratory viruses.

Possible underestimation by sports medicine of the effects of early physical exercise practice on the prevention of diseases in adulthood

In modern society, combatting cardiovascular and metabolic diseases has been highlighted as an urgent global challenge. In recent decades, the scientific literature has identified that behavioral variables (e.g. smoking, unhealthy diet and physical inactivity) are related to the development of these outcomes and, therefore, preventive actions should focus on the promotion of physical exercise practice and a healthy diet, as well as combatting the smoking habit from an early age. The promotion of physical exercise in the general population has been suggested as a relevant goal by significant health organizations around the world. On the other hand, recent literature has indicated that physical exercise performed in early life prevents the development of diabetes mellitus, dyslipidemia and arterial hypertension during adulthood, although this protective effect seems to be independent of the physical activity performed during adulthood. Apparently, the interaction between physical exercise and human growth in early life constitutes an issue which is not completely understood by sports medicine. The aim of the present review was therefore to discuss recent evidence on the effects of physical exercise performed during childhood and adolescence on cardiovascular and metabolic outcomes in adulthood.

Chemical and biological characterisation of Machaerium hirtum (Vell.) Stellfeld: absence of cytotoxicity and mutagenicity and possible chemopreventive potential

Machaerium hirtum (Vell.) Stellfeld (M.hirtum) is a plant known as 'jacarandá-bico-de-pato' whose bark is commonly used against diarrhea, cough and cancer. The aim of this study was to phytochemically characterise the hydroethanolic extract of this plant, investigate its antimutagenic activities using the Ames test and evaluate its effects on cell viability, genomic instability, gene expression and cell protection in human hepatocellular carcinoma cells (HepG2). Antimutagenic activity was assessed by simultaneous pre- and post-treatment with direct and indirect mutagens, such as 4-nitro-o-phenylenediamine (NPD), mitomycin C (MMC), benzo[a]pyrene (B[a]P) and aflatoxin B1 (AFB1), using the Ames test, cytokinesis blocking micronucleus and apoptosis assays. Only 3 of the 10 concentrations evaluated in the MTT assay were cytotoxic in HepG2 cells. Micronucleated or apoptotic cells were not observed with any of the tested concentrations, and there were no mutagenic effects in the bacterial system. However, the Nuclear Division Index and flow cytometry data showed a decrease in cell proliferation. The extract showed an inhibitory effect against direct (NPD) and indirect mutagens (B[a]P and AFB1). Furthermore, pre- and post-treated cells showed significant reduction in the number of apoptotic and micronucleated cells. This effect is not likely to be associated with the modulation of antioxidant genes, as shown by the RT-qPCR results. Six known flavonoids were identified in the hydroethanolic extract of Machaerium hirtum leaves, and their structures were elucidated by spectroscopic and spectrophotometric methods. The presence of the antioxidants apigenin and luteolin may explain these protective effects, because these components can inhibit the formation of reactive species and prevent apoptosis and DNA damage. In conclusion, the M.hirtum extract showed chemopreventive potential and was not hazardous at the tested concentrations in the experiments presented here. Moreover, this extract should be investigated further as a chemopreventive agent.
