A sociologia antropocêntrica de Alberto Guerreiro Ramos
No full textTese (doutorado) - Universidade Federal de Santa Catarina, Centro de Filosofia e Ciências Humanas. Programa de Pós-Graduação em Sociologia Política.No elenco das diferentes modalidades de estudos que sobre o pensamento sociológico de Alberto Guerreiro Ramos já foram realizadas, esta tese se coloca como uma possibilidade de interpretação que propicie aclarar, não as pontualidades temáticas ou as respostas aos problemas contingentes a que este sociólogo se propôs pensar, mas a coerência de suas crenças no tempo. Segundo pensamos, esta interpretação pautada na coerência das crenças guerreirianas pode trazer elucidações fundamentais acerca do alcance, do sentido e da finalidade da construção teórica à qual ele se dedicou, dos principais conceitos, modelos e proposituras por ele construídas, bem como permite justificar a mobilização e apropriação de conceitos e correntes teóricas por ele procedidas. Neste sentido, a tese que aqui se apresenta defende que há, no conjunto da obra de Guerreiro Ramos, uma forte crença da premência de um novo humanismo e, em termos correlatos, de um novo tipo humano, a partir dos quais seria possível teorizar sobre a vida humana individual e associada. Uma expressão marcante dessa crença do autor está na preocupação e no pressuposto por ele assumidos de que a sociedade deveria ser vertida ao homem, e não o inverso. Esta crença tem seu correspondente na afirmativa de Protágoras, e com a qual Aristóteles estava de pleno acordo: anthrôpos metro panthô chrématon (o homem é a medida de todas as coisas humanas). Munido deste humanismo radical, nosso sociólogo passou em revista os pressupostos sobre o homem que legitimavam a ciência social de sua época, denunciou os principais obstáculos sociais impeditivos de um processo de humanização e articulou a sua proposta de uma nova ciência do social. É neste sentido que afirmamos ser antropocêntrica a sociologia de Guerreiro Ramos. Esta pesquisa, assim, atenta para uma questão que até agora é inédita, tendo-se em conta todos os trabalhos que trataram da obra ou dos estudos de Guerreiro Ramos. Several studies about Ramos#s sociological thought have been written in Brazil. The purpose of this dissertation is to be an interpretation to clarify some elements that support the Ramos#s coherence of beliefs in time. This coherence exists in all Ramos#s work, since his juvenile papers until his last book. We believe that our interpretation can be help in the understanding of the reach, of the meaning, and of the final aim of his theoretical work or of his concepts, models, and sociological proposals. Also we believe that our interpretation can help in the understanding of his displacement of concepts and filiations with currents of thought. In this dissertation we demonstrated that there is in the Ramos#s works a strong belief in the urgency of a new humanism, and a new human type, starting from which would be possible to theorize about the individual and associated human life, in others words, a humanism which the man was the measure of everything. An example of this is his concern and presupposition that the society should be structured for the man and not the opposite. With this radical humanist point of view, Ramos revised the man presupposition of the social science of his time, denounced the main social obstacles to the humanization process, and proposed a new science of social. In this way, we affirm that the Ramos#s sociological thought is anthrophocentric
Angústia, de Graciliano Ramos e a deformação expressionista
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Comunicação e Expressão. Programa de Pós-Graduação em Literatura.Este trabalho procura mostrar que a visão distorcida da realidade, própria da arte moderna, não se restringe às artes plásticas. Essa visão, representante de um outro modo de olhar e sobretudo ver o real, encontrou também na obra literária possibilidades de se externar. Angústia, de Graciliano Ramos, inscreve-se na Literatura Brasileira como um romance rico em imagens resultantes da visão deturpada de um narrador em conflito consigo mesmo. A narrativa de Luís da Silva é analisada a partir do poder de visualização do narrador - em seus aspectos subjetivos e sua expressividade - em seus pontos de contato com a pintura expressionista, de modo especial com O Grito, de Edvard Munch

(Barro Colorado Island, Panama) Remarks. This species can be distinguished from S. pluvialis Ramos & Wolda, 1985 by the absence of a spot of infuscation on the apex of the fore wing. This species emerges during the last month of the rainy season and early dry season between late November and February and tends to fly at lower altitudes in the forest based on the majority being captured in the trap near the ground (Ramos & Wolda 1985; Wolda 1977; 1988; 1989; 1993). Distribution. The species is known only from Panama (Sanborn 2013). Panamanian specimens are from Barro Colorado Island, Panama Canal Zone, 120 m altitude in lowland forest (Ramos & Wolda 1985; Wolda 1977; 1988; 1989; 1993; Wolda & Ramos 1992).Published as part of Sanborn, Allen F., 2018, The cicadas (Hemiptera: Cicadidae) of Panama including the description of six new species, three new combinations, one new synonymy, and nine new records, pp. 1-69 in Zootaxa 4493 (1) on page 59, DOI: 10.11646/zootaxa.4493.1.1, http://zenodo.org/record/144516

Nontypes: From the Mucuri River estuary, Mucuri, Bahia state, Brazil: LIUEFS 4454, (1), 76.7 mm SL; September 1999, collected by C. L. S. Sampaio and F. D. Fernandes. LIUEFS 5076 (2), 70.7–72.9 mm SL; September 2000, collected by C. L. S. Sampaio and F. D. Fernandes. Diagnosis: Achirus mucuri n. sp. (Fig. 1) is distinguished from all its congeners, except A. novoae, by possessing a connection on both the blind and ocular sides between the branchiostegal membrane and the isthmus (Fig. 2 a), with the connection being slightly stronger on the blind side (vs. complete absence of connections between branchiostegal membranes and isthmus – Fig. 2 b). Additionally, the new species is distinguished from its congeners by having a light-brown body color, with regularly-scattered, minute, darkbrown blotches that are sometimes concentrated to form larger spots. Five specimens differed from the typical light-brown body color in having a brownish-gray background, and one specimen showed brownish-white body pigmentation. The new species differs from A. novoae by the presence of a large, ramified labial fimbriae (Fig. 3 a–b) (vs. simple, non-ramified, minute labial fimbriae in A. novoae, Fig. 3 c) and by the shape of the infraorbital canal (extending around ventral margin of fixed eye, Fig. 2 c) (vs. infraorbital canal that stops dorsal to fixed eye in A. novoae, Fig. 2 d). Description: Body ovate. Eye comparatively large, its diameter approximately twice the interorbital space. Eyed-side anterior nostril short, its length equal to its diameter, with a small notch on its anterior wall, and very short fimbriae on its margin. Blind-side posterior nostril with thin skin, wide opening, its diameter equal or nearly equal to greatest width of nostril tube (Fig. 3 d–e); two specimens (including holotype) with slightly narrower nostril opening than remaining specimens. Length of labial fimbriae not exceeding that of anterior nostril, and forming stalk supporting two to five ramifications of similar size (Fig. 3 a); some fimbriae with additional ramifications emerging from base of stalk (Fig. 3 b). One to five non-ramified fimbriae close to mouth corner, and one or two close to mandibular symphysis. Lower lip and its fimbriae cover upper lip when mouth closed. Cirri (Fig. 3 f) present on upper lip, and scattered on nasal area. Ventral margin of nasal area also with cirri, and with one or more small fringes (Fig. 3 g–h) on this margin, close to anterior end of nasal area. Branchiostegal membrane slightly connected to isthmus, very weakly on eyed-side of head. Supratemporal canal and epiphyseal branch of latero-sensory cephalic canal system conspicuous. Supratemporal canal arched posteriorly, extending dorsally (Fig. 2 c); epiphyseal branch extending anteriorly and dorsally, its proximal part close and parallel to migrated eye, its distal end almost reaching dorsal-fin base (Fig. 2 c); orientation of both canals can be slightly displaced dorsally or ventrally relative to position represented in Figure 2 c. Other canals with a typical pattern of other achirid species (except A. novoae for infraorbital canal), as stated and illustrated (Fig. 1) by Ramos (2003 b); holotype with uncommon external connection between distal end of infraorbital canal (at ventral margin of fixed eye) and ventral portion of preopercular canal. Dorsal-fin rays 48–57; anal-fin rays 38–42; eyed-side pectoral-fin rays 3–6, blind-side pectoral-fin rays absent; eyed-side pelvic-fin rays 5, blind-side pelvic-fin rays 4–5; caudal-fin rays 13–16. Total vertebrae 27: precaudal vertebrae 9, caudal vertebrae 18. Supracranial proximal radials 6. Longitudinal series of scales 57–62. Morphometric data shown in Table 1. Eyed side. All scales ctenoid, absent from nasal area, lips, margin of preopercle, margin of gill opening, and inter-radial membranes. Dorsal-, anal- and pelvic-fin rays with series of larger scales along their posterior margins. Larger scales preceded by two series of irregularly ordered, smaller scales that extend only on proximal half of each ray; posteriormost rays support only one or two incomplete series of scales. Dark brown cirri present on lateral surfaces of dorsal-, pelvic-, and anal-fin rays, and scattered on trunk, more evident on darkly-pigmented areas. Lateral-line on trunk with simple (non-ramified) tubes. Blind side. All scales ctenoid, absent from nasal area, lips, margin of preopercle, margin of gill opening, central region of opercular area, and inter-radial membranes. Fringes with a large, rounded basal flap (Fig. 3 i) and cirri in relatively small numbers, present only on head, more numerous on anterior margin of supracranial and infracranial areas, nasal area, and around mouth. Cirri rare or absent on trunk, except for regularly-spaced cirri along anterior third of lateral-line; cirri replaced by paired or unpaired small fringes on meddle and posterior third of lateral line. Fringes and cirri present on posterior margin of each dorsal-fin ray; more numerous on those in anterior one-third of fin. Fringes and cirri reduced in number posteriorly, and absent on posteriormost rays. Cirri present on all pelvic-fin rays, and on rays of anterior one-third of anal fin. Lateral line dermal tubes on trunk, when present, minute. Coloration: General body coloration usually light brown to light gray, occasionally (one specimen) brownish-white. Regularly-scattered, minute, dark-brown blotches present on head, trunk and fins and sometimes concentrated to form larger spots. Seven specimens (including holotype) with dark-brown irregular blotches on blind-side caudal-fin base. Vertical lines of chromatophores (achirine lines) faint, sometimes not visible. Coloration on fins more pronounced on rays than interradial membranes, but fins generally of a uniformly pale pigmentation similar to that of body. Distribution: Achirus mucuri n. sp is known only from the Mucuri River estuary, a small system situated between the Jequitinhonha and Doce rivers, south of Bahia state coast drainage, northeastern Brazil. Habitat: No data exist regarding its habitat preferences within the estuarine environment.Published as part of Ramos, Robson T. C., Ramos, Telton P. A. & Lopes, Paulo R.

No full textThe role of brain noradrenaline in Alzheimer's disease: Implications for a precision medicine-oriented approach
No full textIn the context of Precision Medicine for Alzheimer's Disease, the assessment of the central noradrenergic system might be key for optimizing the management of cognitively impaired patients. The Locus Coeruleus, the main noradrenergic nucleus of the brain, is involved early and dramatically in Alzheimer's Disease, and the loss of its function may have detrimental consequences. Recent advances in diagnostic technology have enabled in vivo evaluation of the integrity and functionality of the Locus Coeruleus, revealing the characteristics of this otherwise hidden nucleus. This new perspective may lead to novel therapeutic approaches that specifically target the noradrenergic system in Alzheimer's Disease
Results of the Heart Protection Study: Can we still assume a class effect?
No full textStatins share several common features including the mechanism of action, i.e. inhibition of HMG-CoA reductase, as well as LDL-cholesterol (LDL-C) and triglyceride lowering properties. However, statins show minor differences in chemical structure, lipophilicity that could translate into a different pharmacological properties. For example, simvastatin exerted a more favorable effect on HDL-C levels than did atorvastatin when higher doses of the two drugs were compared. Finally, the major considerations to chose between statins for CVD patient therapy include clinical benefits and safety (i.e. evidence-based medicine). Primary prevention trials with pravastatins and lovastatin and secondary prevention trials with pravastatin, fluvastatin and simvastatin have established the clinical benefits of statins. In addition, HPS study was designed to investigate the benefits of simvastatin 40 mg in a broad range of patients at high risk for heart disease including women, the elderly and those with a history of hearth attacks, diabetes, hypertension or vascular disease. The results show the ability of simvastatin to reduce all causes of mortality, vascular death and cardiovascular morbidity. The trial also confirms the safety of simvastatin 40 mg although 60% of patients were receiving additional pharmacological treatment. In summary, it appears that statins are not the same and the choice of the more appropriate statin in high-risk patients should be driven by the evidence-based medicine both in terms of safety and efficacy
