MARREGA, M. F Ser homem de 45 a 55 anos na relação heterossexual: da ruptura do silêncio a reflexões de paradigmas. 2005. 319 p. Dissertação. FFCLRP- Universidade de São Paulo, Ribeirão Preto, 2005. Resumo A heterossexualidade se apresenta como padrão de sexualidade instituído como norma sexual adequada, portanto pouco investigado. A definição de homem como chefe do lar, forte, inatingível emocionalmente, consiste na oposição da idéia do conceito do que é ser mulher, considerada sensível, frágil e passiva. Esse conceito patriarcal possui como paradigma uma definição clara de papéis de gênero, sendo legitimado pela divisão social de trabalho, na qual os homens situam-se na esfera pública da sociedade, provendo materialmente a família, enquanto as mulheres são aptas à esfera privada, zelando pelo lar e pelos filhos. Entretanto, as conquistas sexuais das mulheres e sua inserção no mercado de trabalho, ocasionaram mudanças nesse cenário. Isso juntamente com as conquistas dos homossexuais e transexuais desencadeou mudanças significativas nos papéis de gênero e na estrutura familiar. Assim, essa pesquisa visa compreender como homens de meia-idade que se autodenominam heterossexuais vivenciam e significam suas experiências afetivas e sexuais...
A pesquisa aborda a compreensão da relação sociedade-natureza no campo, através do estudo de caso da Comuna da Terra Irmã Alberta, estabelecida como assentamento rural pelo Movimento dos Trabalhadores Rurais Sem Terra (MST), desde 2002, no distrito de Perus, município de São Paulo/SP e em processo de regularização pelo INCRA. Houve a preocupação de apreender a influência do meio físico na determinação dos modos de exploração agrícola da área em questão e o impacto desses sistemas de produção agrícola na dinâmica da paisagem, problematizando as práticas das famílias em relação à gestão do meio físico. Nesse sentido, entende-se que há uma produção da paisagem pelo processo histórico de apropriação da terra e vice-versa. A reconstituição histórica da estrutura agrária da região e a elaboração dos mapeamentos temáticos do meio físico subsidiaram o estudo das interações dos sistemas pedológicos e os sistemas de produção agrícola do assentamento. A caracterização dos sistemas pedológicos se deu a partir da caracterização do impacto das ações antrópicas sobre a morfologia dos solos através da técnica do Perfil Cultural. O trabalho abrange, ainda, a discussão das limitações da modalidade de assentamento rural de Desenvolvimento Sustentável...
A newly devised dual labeled iodine isotopic method is described for the detection and quantitation of alterations in thyroxine (T4) deiodination rate in man. This method employs the principle of a constant 125I infusion to serve as a reference source for the generation of 131I derived from the deiodination of T4-131I. Measurement of these two iodide isotopes are made in serially timed urine collections and are expressed in terms of a ratio value. Using this technique, it was possible to measure accurately the effects of a single dose of 6-propylthiouracil (6-PTU) in producing inhibition of T4 deiodination in euthyroid subjects. It was also possible to assess the time of onset, duration of action, and degree of inhibition produced by 6-PTU. Employing single doses of 6-PTU, ranging from 100 to 1000 mg, there was found to be a log dose relationship with a degree of inhibition observed in T4 deiodination. In control studies T4 deiodination rate was found to be constant for periods ranging up to 72 hr in normal ambulating subjects. The acute administration of many other agents was employed in an attempt to alter the T4 deiodination rate. These included diphenylhydantoin, methimazole, triiodothyronine, thyroxine, thyroid stimulating hormone (TSH)...
We describe here and validate an in vivo technique to measure the regional proportionate removal of norepinephrine (NE) by neuronal uptake (Uptake1) in man. The measurement is based on the steady-state arterial and venous concentrations of tritiated NE and tritiated isoproterenol (ISO) during simultaneous infusion of both. The validity of this technique depends on the removal of circulating NE, but not of ISO, by sympathetic nerve endings and on there being no other factor contributing to the net difference in the plasma disappearance of these catecholamines. To test these hypotheses, we compared the removal of NE in the arm with that of ISO in 14 people and the effects of pretreatment with the specific inhibitor of Uptake1, desipramine, in 8 people. In all the subjects a greater percent of NE than of ISO was removed during passage of blood through the forearm (54 vs. 46%, P less than 0.0001). Pretreatment with desipramine decreased significantly the removal of NE to virtually exactly that of ISO. The difference in NE and ISO clearances by arm tissues was therefore completely accounted for by Uptake1. About 15% of infused NE which is removed in the arm is removed by Uptake1. The ability to measure regional Uptake1 should contribute to better understanding of the relationship between circulating levels of plasma NE and sympathetic neural activity and may allow detection of abnormalities of neuronal norepinephrine removal in clinical disease states.
We have studied the relationship between in vivo insulin-mediated glucose disposal rates, muscle glycogen content, and muscle glycogen synthase activity in 25 southwest American Indians with normal glucose tolerance and with varying degrees of glucose intolerance. Insulin-mediated glucose disposal (M) was measured by using the hyperinsulinemic euglycemic clamp technique at plasma insulin concentrations of 134 +/- 7 and 1709 +/- 72 microU/ml, with simultaneous indirect calorimetry to assess glucose oxidation and storage rates. Muscle glycogen content and glycogen synthase activity were measured in percutaneous muscle biopsy samples obtained from the vastus lateralis muscle before and after the euglycemic clamp procedure. The results showed that muscle glycogen synthase activity at the end of the euglycemic clamp was well correlated with insulin-mediated glucose storage rates at both low (r = 0.50, P less than 0.02) and high (r = 0.78, P less than 0.0001) insulin concentrations; and also correlated with M (r = 0.66, P less than 0.001 and r = 0.76, P less than 0.0001). Similar correlations were observed between the change in muscle glycogen synthase activity and glucose storage rates and M. The change in muscle glycogen synthase activity correlated with the change in muscle glycogen content (r = 0.46...
The effect of cigarette smoke exposure on pulmonary epithelial permeability was studied in 45 smokers and 22 non-smokers. An index of cigarette smoke exposure was obtained from the carboxyhaemoglobin concentration (HbCO%). Pulmonary epithelial permeability was proportional to the half-time clearance rate of technetium-99m-labelled diethylene triamine pentacetate (99mTc DTPA) from lung to blood (T1/2LB). The relationship between T1/2LB and HbCO% was hyperbolic in form and the data could be fitted to the quadratic formula (formula; see text) where the parameters a0, a1, and a2 represent respectively the asymptotic T1/2LB value at large carboxyhaemoglobin values and the slope and shape of the curve. The values of these parameters were a0 4.4 (2.6), a1 = 77.8 (15.5), and a2 -25.5 (9.7) (SE). This is the first demonstration of a dose-response relationship between carboxyhaemoglobin and an increased permeability of the lungs in man and provides a technique for identifying the roles of carbon monoxide and other cigarette smoke constituents in causing increased pulmonary epithelial permeability.
The aim of this study was to test the reliability of the commonly used blocking technique for measuring the conduction velocity spectrum of the peripheral motor nerve in man, as first described by Hopf in 1962. Electromyographic recordings were carried out with a selectivity permitting identification of single motor unit potentials. The conduction velocity of the single alpha motor axon was determined by a direct technique and by the blocking technique. the refractory period was determined by comparison of the results of these two techniques. The refractory period was studied in relation to the strength of the testing stimulus, axonal conduction velocity, skin temperature and age of the subject. When the strength of the test stimulus increased from 10% to 50% above the axonal threshold, the refractory period decreased from 1.7 to 0.6 ms. An inverse relationship between the axonal conduction velocity and the refractory period was observed. When skin temperature was 4 degrees C subnormal the refractory period was significantly prolonged; at 10 degrees C subnormal it was more than doubled. The same relationship between axonal conduction velocity and the refractory period was observed in both young and elderly subjects. The significance of these findings for the clinical application of the blocking technique is discussed.
1. Venous congestion strain-gauge plethysmography enables the non-invasive assessment of arterial blood flow, fluid filtration capacity (Kf), venous pressure (Pv) and isovolumetric venous pressure (Pvi) in man. One of the major assumptions of this technique, that cuff pressure (Pcuff) applied to the limb equals Pv at the level of the strain gauge, was tested in this study. 2. In nine healthy male volunteers (mean age, 29.3 +/- 1.2 years) the saphenous vein was cannulated with an 18-gauge catheter proximal to the medial malleolus. The subjects were supine and Pv was continuously measured during the application of small step (8-10 mmHg) increases in congestion Pcuff (up to 70 mmHg). Pcuff, changes in limb circumference and Pv were recorded by computer for off-line analysis. Since the determination of Kf is influenced by the changes in plasma oncotic pressure, venous blood samples were obtained at the start of the study, when Pcuff was raised to 30 mmHg and again to 65 mmHg and 4 min after deflation of the cuff. 3. The relationship between Pv and Pcuff was linear over the range of 10-70 mmHg (n = 9, 69 measurements, slope 0.91, r = 0.97, P << 0.001). The non-invasively measured calf Pv, based on the intercept of the relationship between the vascular compliance component (Va) and Pcuff...
Using a duodenal perfusion technique, the biliary output of bile acids, phospholipid, and cholesterol was measured hourly during three meals and an overnight fast in seven Caucasians with radiolucent gallstones in a functioning gallbladder, and in seven health controls without gallstones, closely matched for age, sex, and weight. Before the perfusion, bile acid kinetics were defined by an isotope dilution procedure, and the biliary lipid composition of fasting gallbladder bile was determined. Total daily biliary lipid output was similar in gallstone and control subjects, and was unrelated to cholesterol saturation of fasting gallbladder bile and to bile acid pool size. There was an inverse relationship between the size and recycling frequency of the bile acid pool, so that secretion rate and hepatic return of bile acids remained constant, despite a wide range of pool sizes. The finding of a normal bile acid synthesis rate in subjects with a small pool size therefore indicated normal feedback regulation of bile acid synthesis. Hourly measurements of biliary lipid output showed a linear relationship between bile acid and cholesterol output, with a similar regression line for gallstone and control subjects, but a non-linear relationship between bile acid and phospholipid output. Consequently...
The in vitro water-holding properties of 17 dietary fibre preparations, mainly food materials, bulk laxatives, and gel-forming polysaccharides, have been measured. Water uptake was measured by a centrifugation technique and also by a new method using sacs of dialysis tubing containing the material, immersed in simulated gut contents. The centrifugation technique could not be applied to gel-forming polysaccharides but the methods gave broadly similar results for other materials (r=0·85). The gel-forming polysaccharides in general held more water than the food fibres. Studies of matched pairs of materials which differed only slightly in chemical composition suggested that the presence of charged groups on the molecule encouraged water uptake. In the food materials water uptake was related to uronic acid content (r=0·87). Materials ground to a smaller particle size increase their water holding but this effect was small (+28%). The hypothesis that dietary fibre increases faecal bulk by virtue of its ability to hold water was tested by comparing the in vitro water-holding capacity of eight of the fibres with the changes they had produced when fed to human volunteers under controlled conditions. Of these materials pectin had the greatest water-holding capacity (56·2 g water/g material) but produced the smallest change in faecal weight (19%)...
BNP (B-type natriuretic peptide) has been reported to be elevated in preclinical states of vascular damage. To elucidate the relationship between plasma BNP and endothelial function, we have investigated the relationship between BNP and endothelial function in a cohort of subjects comprising healthy subjects as well as at-risk subjects with cardiovascular risk factors. To also clarify the relative contribution of different biological pathways to the individual variation in endothelial function, we have examined the relationship between a panel of multiple biomarkers and endothelial function. A total of 70 subjects were studied (mean age, 58.1±4.6 years; 27% had a history of hypertension and 18% had a history of hypercholesterolaemia). Endothelium-dependent vasodilatation was evaluated by the invasive ACH (acetylcholine)-induced forearm vasodilatation technique. A panel of biomarkers of biological pathways was measured: BNP, haemostatic factors PAI-1 (plasminogen-activator inhibitor 1) and tPA (tissue plasminogen activator), inflammatory markers, including cytokines [hs-CRP (high sensitive C-reactive protein), IL (interleukin)-6, IL-8, IL-18, TNFα (tumour necrosis factor α) and MPO (myeloperoxidase] and soluble adhesion molecules [E-selectin and sCD40 (soluble CD40)]. The median BNP level in the study population was 26.9 pg/ml. Multivariate regression analyses show that age...
This is a theoretical study devoted to reconstructing conceptions of nature-care-ethics theme, in an expository approach of Martin Heidegger (2002) ideas, in conversation with Hans Jonas (2004-2006), aiming, in the future, to subsidize the philosophical foundations an environmental education methodology. The research method was the phenomenological hermeneutics of Heidegger, expressed in his work Being and Time . The basis of reflection is the relationship between man and nature, its actual sense and verifying that Care (Sorge) can serve as critical to our civilization and as a guiding principle of convivial with nature. If the technique and technology take on a new sense of ethics because of the central role they now occupy, it will be able to come to a state of irreversibility for nature and human life, requiring that human behavior becomes duty subject. The ethics need will be exponentially greater as much as the powers of human action are governed by it. Only an ethics based on the human being, maintenance and custody of existence can have an effective sense. This indicates that care takes on the original centrality and provides a lumen to the merits of its value and its meaning to life that causes one diverse devise to the society. Care should constitute the root of ethics...

Relatório Final de Estágio apresentado à Escola Superior de Dança, com vista à
obtenção do grau de Mestre em Ensino da Dança.; A expressividade nas aulas de Técnica de Dança Clássica foi o tema escolhido para
este projeto de estágio curricular, no âmbito do Mestrado em Ensino de Dança, da
Escola Superior de Dança. O objetivo a que nos propusemos, vai para além de
refletir sobre a relação entre técnica e expressividade na dança, visando estimular e
valorizar a expressividade nas aulas de Técnica de Dança Clássica, não só como
elemento potenciador de uma técnica sólida, mas também como fator responsável
pela exteriorização de intenções, sentimentos e ações, inerente ao Homem.
Procurou-se relevar a importância do domínio técnico do bailarino, sem contudo
descurar nem inibir a sua expressão. O aluno/bailarino deve traduzir no movimento
consolidado tecnicamente, as suas experiências, a sua identidade, a expressão
integral da dança – expressividade da técnica e expressão interior - reforçando a
importância de uma comunicação mais verdadeira entre bailarinos e públicos. Neste
sentido, o papel da técnica é também colocado em relevo, na medida em que esta
agiliza e suporta a expressividade do movimento.; ABSTRACT - Expressiveness in Classical Dance Technique classes was the theme chosen for this
For Heidegger, the essence of modern technology is a mode of revealing the Being; namely, a way to emerge from concealment that has the character of summoning Nature in the sense of “provocation”. The greatest danger this technological mode of revelation represents for man is that any other mode of revelation might be expelled and man could lose the relationship with his de-concealing essence of worlds. However, as Hölderlin poetically says: but where the danger is, grows the saving power. For Heidegger, this means the saving power also grows within the bosom of technology. Unraveling this paradox necessitates a decisive showdown with technology in the field of art. In this paper, the authors develop an interpretation of this enigmatic Heideggerian proposal.; Para Heidegger la esencia de la técnica moderna es un modo de revelado del Ser, es decir, un modo de hacer salir de lo oculto, que tiene el carácter de emplazar la Naturaleza en el sentido de “la provocación”. El mayor peligro que este modo de revelado tecnológico representa para el hombre es que cualquier otra forma de revelado sea expulsada, y el hombre pierda relación con su esencia des-ocultadora de mundos. Pero por otra parte, Hölderlin poéticamente lo anuncia: allí donde está el peligro crece el poder salvador. Esto significa para Heidegger que en el seno de la técnica también crece el poder salvador. Desentrañar esta paradoja nos demanda una confrontación decisiva con la técnica en la región del arte. En el presente escrito desarrollaremos una interpretación de esta enigmática propuesta heideggeriana.; Pour Heidegger...
The single-channel inside-out patch clamp technique was used to characterize chloride channels in the apical membranes of human airway epithelial cells maintained in primary culture. Patches were obtained from single isolated cells or from cells at the edges of confluent groups. The channel seen most often, in 24% of all patches, had a conductance of approximately 20 pS and had a linear current-voltage relationship in symmetric chloride solutions. The anion selectivity sequence for the channel was NO3- greater than Cl- greater than HCO3-, and it was impermeable to gluconate ions, indicating that the channel diameter lies between 4.7 and 5.5 A. Current through the channel saturated at high chloride concentrations, and the relationship between channel current and chloride concentration could be approximated by the Michaelis-Menten equation. Analysis of the channel's anion permeability and its current vs. concentration relationship indicates that it can be described by the one-ion channel theory, with a relatively weak binding site inside the channel. Histograms of channel open and closed durations were constructed using the log binning technique and could be well fitted by triple exponential distributions, suggesting that the channel has at least three open and three closed states.
Without the pursuit of love and happiness, breath is simply the sand of an hourglass pouring away to our time of passing. Love is the reason we are alive. To spend even a moment in misery is a moment wasted.
Love is the goal of humanity. Everyone has or will experience love in its many forms over the course of a lifetime. Many, out of ignorance, habit, or sheer desperation, will fall in love with the wrong person. Most of us have or will have that one failed relationship, the one we reflect on as the relationship that taught us the most about who we are, what makes us happy, and what we seek or try to avoid in a mate. Through failure we learn what we can improve about ourselves. We learn that there are no perfect people and to try to make them that way is a losing battle, a never-ending, fruitless effort. Regardless, we will always try.
Our happiness is dependent upon our honesty in defining ourselves. That is, if you are not happy, you cannot make yourself so simply by ignoring your own needs and catering to the needs of others. Additionally, you cannot make others happy by projecting your happiness upon them. When we are happy, we are being honest, even if only with ourselves. Unhappiness is wanting. If our needs are not being met...
This paper is a companion piece to my short film, “Victorian Organ”. This film is
an effort to contextualize the mechanical, or man-made, within nature. It is an
assertion that there really is no "man vs. nature"- (a radically illogical and
inherently self-destructive notion), but only man as nature, in which case,
alienation and disharmony ultimately lies in our own self-perception.
The impulse to identify a relationship between the mechanical and organic is
inspired not only by my observations of our human society, but as a way to
decode my own inner workings –an urge to reconcile seemingly major
dichotomies like reason and emotion.
In the film, these ideas are illustrated by pulling the viewer through the innards
of a self-winding, mechanically musical tree. The central metaphor is the
encrypted code of the music box cylinder at the heart of the tree, whose rotating
bumps dictate not only the notes of the tree’s song, but the pattern of cell
growth-- a spinning mechanical chromosome. The cylinder is wound by a key
nested in the center of the root structure, pushed by the tree’s own organically
formed roots. The key eventually reaches its extreme point and reverses
direction, turning the cylinder and playing out its code like a music box. This
winding and unwinding is in keeping with the dual nature of the tree...
This thesis is a conceptual look at the relationship between mankind and
nature. Initially this was to be accomplished using blown glass forms in conjunction
with fabricated or found objects such as tool or machine parts. This idea eventually
evolved into the use of vessels and organic glass forms to achieve the same objectives.
There are two major components of this thesis. The first section will explain the
concept behind my thesis statement that is a relationship exists between man and
nature. It will also be a vague outline showing the stages of thought that lead to me to
my final pieces. The second section will explain the technical processes and what
knowledge I gained from these processes. This thesis is an attempt to show the direct
correlation and relationship between human life and nature.
The balance between the human race and nature has been unequally weighted
for many years throughout history. From the beginning of the Industrial Revolution to
modern day technology, man has continued to exert its control over nature. Once we,
the human race, became aware that we could benefit from controlling nature, we used
it to further our needs. Today man kind is slowly becoming more aware of the loss of
the very precious balance it once had with nature.
Artists use their medium to arouse questions dealing with issues that they feel
are important. As a glass blower...
I am fascinated by the relationship of modern humans to the natural world, and the ways in which the technology we produce has both positive and negative impacts on it. I want to use my work to create a non-biased, beautiful environment in which others can also contemplate this subject. Clay is an important material not only for its elemental symbolism of earth, but also for its long ties to human craft and culture. Plastics are advanced synthetic materials with various ecologically constructive and destructive aspects in a field with increasing emphasis on environmental sustainability. The synthesis of these two media is technically and aesthetically intriguing to me. I think that creating an installation with them is a good way to construct an atmospheric setting in a gallery space.
For my graduate thesis, I propose to make an installation exploring the dialogue between man and the natural world. I plan to use the gallery space at the Hungerford Building to create an environment resembling a river, with "rocks" formed from clay and inlaid with plastic sheets. I will experiment to incorporate clay from the Genesee River into the sculpture clay body I use to form these rocks to bind the work deeply to the location. They will emit light through the translucent plastic...
