Authors: Proctor David N. , Miller Jordan D. , Dietz Niki M. , Minson Christopher T. , Joyner Michael J.
Published: December 2017

This study evaluated the hypothesis that active muscle blood flow is lower during exercise at a given submaximal power output after aerobic conditioning as a result of unchanged cardiac output and blunted splanchnic vasoconstriction. Eight untrained subjects (4 men, 4 women, 23–31 yr) performed high-intensity aerobic training for 9–12 wk. Leg blood flow (femoral vein thermodilution), splanchnic blood flow (indocyanine green clearance), cardiac output (acetylene rebreathing), whole body O2 uptake (V˙o 2), and arterial-venous blood gases were measured before and after training at identical submaximal power outputs (70 and 140 W; upright 2-leg cycling). Training increased ( P < 0.05) peak V˙o 2(12–36%) but did not significantly change submaximalV˙o 2 or cardiac output. Leg blood flow during both submaximal power outputs averaged 18% lower after training ( P = 0.001; n = 7), but these reductions were not correlated with changes in splanchnic vasoconstriction. Submaximal leg V˙o 2 was also lower after training. These findings support the hypothesis that aerobic training reduces active muscle blood flow at a given submaximal power output. However, changes in leg and splanchnic blood flow resulting from high-intensity training may not be causally linked.
Overexpression of TGF-α increases lung tissue hysteresivity in transgenic mice
Authors: Pillow Jane J. , Korfhagen Thomas R. , Ikegami Machiko , Sly Peter D.
Published: December 2017

Increased transforming growth factor (TGF)-α has been observed in neonatal chronic lung disease. Lungs of transgenic mice that overexpress TGF-α develop enlarged air spaces and pulmonary fibrosis compared with wild-type mice. We hypothesized that these pathological changes may alter the mechanical coupling of viscous and elastic forces within lung parenchyma. Respiratory impedance was measured in open-chested, tracheostomized adult wild-type and TGF-α mice by using the forced oscillation technique (0.25–19.63 Hz) delivered by flexiVent (Scireq, Montreal, PQ). Estimates of airway resistance (Raw), inertance (I), and the coefficients of tissue damping (GL) and tissue elastance ( HL) were obtained by fitting a model to each impedance spectrum. Hysteresivity (η) was calculated as GL/ HL. There was a significant increase in η ( P < 0.01) and a trend to a decrease in HL( P = 0.07) of TGF-α mice compared with the wild-type group. There was no significant change in Raw, I, or GL. Structural abnormality present in the lungs of adult TGF-α mice alters viscoelastic coupling of the tissues, as evidenced by a change in η.
Testosterone-induced relaxation of rat aorta is androgen structure specific and involves K+channel activation
Authors: Ding Andrew Q. , Stallone John N.
Published: December 2017

Recent studies have established that testosterone (Tes) produces acute (nongenomic) vasorelaxation. This study examined the structural specificity of Tes-induced vasorelaxation and the role of vascular smooth muscle (VSM) K+channels in rat thoracic aorta. Aortic rings from male Sprague-Dawley rats with (Endo+) and without endothelium (Endo−) were prepared for isometric tension recording. In Endo− aortas precontracted with phenylephrine, 5–300 μM Tes produced dose-dependent relaxation from 10 μM (4 ± 1%) to 300 μM (100 ± 1%). In paired Endo+ and Endo− aortas, Tes-induced vasorelaxation was slightly but significantly greater in Endo+ aortas (at 5–150 μM Tes); sensitivity (EC50) of the aorta to Tes was reduced by nearly one-half in Endo− vessels. Based on the sensitivity (EC50) of Endo− aortas, Tes, the active metabolite 5α-dihydrotestosterone, the major excretory metabolites androsterone and etiocholanolone, the nonpolar esters Tes-enanthate and Tes-hemisuccinate (THS), and THS conjugates to BSA (THS-BSA) exhibited relative potencies for vasorelaxation dramatically different from androgen receptor-mediated effects observed in reproductive tissues, with a rank order of THS-BSA > Tes > androsterone = THS = etiocholanolone > dihydrotestosterone ≫ Tes-enanthate. Pretreatment of aortas with 5 mM 4-aminopyridine attenuated Tes-induced vasorelaxation by an average of 44 ± 2% (25–300 μM Tes). In contrast, pretreatment of aortas with other K+channel inhibitors had no effect. These data reveal that Tes-induced vasorelaxation is a structurally specific effect of the androgen molecule, which is enhanced in more polar analogs that have a lower permeability to the VSM cell membrane, and that the effect of Tes involves activation of K+efflux through K+channels in VSM, perhaps via the voltage-dependent (delayed-rectifier) K+channel.
Selected Contribution: Effects of sex and ovariectomy on responses to platelets in porcine femoral veins
Authors: Lewis D. A. , Bracamonte M. P. , Rud K. S. , Miller V. M.
Published: December 2017

Estrogen replacement increases risk of venous thrombosis. In this study, we determined responses in vitro to platelets and platelet products in veins from adult male and intact and ovariectomized female pigs. When contracted with prostaglandin F2α, platelets (25,000 platelets/μl) caused relaxation in veins with endothelium. Higher numbers of platelets caused contraction in veins with and without endothelium. In veins without endothelium, contractions were greater in veins from male than in veins from female pigs, and contractions in intact female pig veins were greater than in ovariectomized females pig veins. Platelet products 5-hydroxytryptamine and thromboxane (analog U-46619) caused comparable contractions in all veins; contractions to prostacyclin were less in veins from intact female pigs. ADP caused comparable endothelium-dependent relaxations in all groups. These relaxations were increased by indomethacin in veins from intact males and females; with inhibition of nitric oxide, relaxations were comparable in all groups. These results suggest that venous responses to platelets vary with sex and presence of ovaries in female pigs. These variations reflect differences in type and quantity of substances released from platelets as well as the sensitivity of the smooth muscle to some vasoactive substances. In addition, products of cyclooxygenase may reduce endothelium-dependent relaxations in veins.
Selected Contribution: Time-dependent hypoxic respiratory responses in female rats are influenced by age and by the estrus cycle
Authors: Zabka A. G. , Behan M. , Mitchell G. S.
Published: December 2017

Age affects time-dependent respiratory responses to episodic hypoxia in male rats, particularly long-term facilitation (LTF), a serotonin-dependent respiratory “memory” [Zabka AG, Behan M, and Mitchell GS, J Physiol (Lond) 531: 509, 2001]. Because age and gender influence serotonergic function, we tested the hypotheses that the short-term hypoxic response (STHR), posthypoxia frequency decline (PHFD) and LTF of phrenic and hypoglossal (XII) motor output change with age and stage of the estrus cycle in female rats. Young (3–4 mo) and middle-aged (13 mo) female Sprague-Dawley rats were anesthetized, paralyzed, vagotomized, and ventilated. STHR was measured during and PHFD after the first of three 5-min episodes of isocapnic hypoxia (arterial Po 2 35–45 Torr). LTF was assessed 60 min postepisodic hypoxia. Phrenic and XII STHR increased with age ( P < 0.05). PHFD was unaffected by age or gender. Phrenic LTF increased with age in both estrus and diestrus ( P < 0.05), whereas XII LTF increased in middle-aged female rats during diestrus only. Age and gender influence time-dependent hypoxic phrenic and XII responses in a complex manner.
Interdependence of flow between lobes reduces maximal emptying postresection in dogs
Authors: Ewing-Bui David , Mink Steven N.
Published: December 2017

The effect of pulmonary resection on the maximal emptying of the remaining lobes was examined in an open-chest preparation in normal canine lungs and in a unilobar papain emphysema model. The objectives were to determine whether, compared with when both lungs were deflated (BL), maximal emptying of the normal lower lobes or the emphysematous right lower lobe would be altered 1) when acute pneumonectomy of the contralateral lung was performed (OL) and 2) when the lower lobe deflated alone (LA). The alveolar capsule technique was used to measure alveolar pressures (Palv) at 75, 50, and 30% lobar vital capacity (VC). During forced deflation, the maximal rates of deflation (dPalv/d t) and flows (lobarV˙max) of the lower lobes were determined under the three different conditions. The Pitot-static tube technique was used to measure intrabronchial pressures and to estimate bronchial area and compliance in which values were obtained at the same central airway during the conditions studied. The results showed that, compared with BL and OL, dPalv/d t and lobarV˙max decreased during LA ( P < 0.05). These findings were due to a reduction in bronchial area during LA that limited flow at a lower maximal value compared with BL. This decrease in area appeared to be due to a change in bronchial pressure area behavior that resulted in a smaller bronchial area during LA for similar transmural pressures between conditions. There were no differences in findings between normal and emphysematous lobes. This study suggested that removal of lobes may alter the pressure area behavior of central airways. Possible mechanisms considered were differences in axial tension between conditions, negative effort dependence, or parenchymal-bronchial interdependence that may be relevant to understanding the dynamic collapsibility of central as well as intraparenchymal airways.
Blood pressure and mesenteric resistance arterial function after spaceflight

Published: December 2017

Ground studies indicate that spaceflight may diminish vascular contraction. To examine that possibility, vascular function was measured in spontaneously hypertensive rats immediately after an 18-day shuttle flight. Isolated mesenteric resistance arterial responses to cumulative additions of norepinephrine, acetylcholine, and sodium nitroprusside were measured using wire myography within 17 h of landing. After flight, maximal contraction to norepinephrine was attenuated ( P < 0.001) as was relaxation to acetylcholine ( P < 0.001) and sodium nitroprusside ( P < 0.05). At high concentrations, acetylcholine caused vascular contraction in vessels from flight animals but not in vessels from vivarium control animals ( P < 0.05). The results are consistent with data from ground studies and indicate that spaceflight causes both endothelial-dependent and endothelial-independent alterations in vascular function. The resulting decrement in vascular function may contribute to orthostatic intolerance after spaceflight.
Effects of acute intravenous aldosterone administration on Na+, K+, and water excretion in the horse
Authors: Jansson Anna , Lindholm A. , Dahlborn Kristina
Published: December 2017

The effect of a temporary increase in plasma aldosterone concentration on Na+, K+, and water balance was investigated in four horses. Aldosterone was injected intravenously for 6 h at 20-min intervals (total 5.4 μg/kg body wt). Samples were taken for 24 h before, during, and for 48 h after the treatment. Aldosterone treatment reduced the Na+loss via urine and feces by 99 and 72%, respectively, later followed by a marked increase in Na+excretion by both pathways. During the first 6 h after the treatment, fecal K+excretion was elevated, and the plasma K+concentration was lowered. Fluid was retained throughout the treatment period and for 12–15 h thereafter. In a second experiment, exercise was performed once after aldosterone treatment and once without prior treatment. Sweat samples were collected, and the composition was not altered after treatment. It was concluded that acute aldosterone injections reduce Na+losses in both feces and urine but not in sweat. In addition, the feces was shown to be the main excretion pathway of aldosterone.
Differential effects of soluble and particulate guanylyl cyclase on Ca2+sensitivity in airway smooth muscle
Authors: Rho Edwin H. , Perkins William J. , Lorenz Robert R. , Warner David O. , Jones Keith A.
Published: December 2017

Maximal relaxation of airway smooth muscle (ASM) in response to atrial natriuretic peptide (ANP), which stimulates particulate guanylyl cyclase (pGC), is less than that produced by nitric oxide (NO) and other compounds that stimulate soluble guanylyl cyclase (sGC). We hypothesized that stimulation of pGC relaxes ASM only by decreasing intracellular Ca2+concentration ([Ca2+]i), whereas stimulation of sGC decreases both [Ca2+]iand the force developed for a given [Ca2+]i(i.e., the Ca2+sensitivity) during muscarinic stimulation. We measured the relationship between force and [Ca2+]i(using fura 2) under control conditions (using diltiazem to change [Ca2+]i) and during exposure to ANP, diethylamine-NO (DEA-NO), sodium nitroprusside (SNP), and the Sp diastereoisomer of β-phenyl-1, N2-etheno-8-bromoguanosine-3′,5′-cyclic monophosphorothionate ( Sp-8-Br-PET-cGMPS), a cell-permeant analog of cGMP. Addition of DEA-NO, SNP, or Sp-8-Br-PET-cGMPS decreased both [Ca2+]iand force, causing a significant rightward shift of the force-[Ca2+]irelationship. In contrast, with ANP exposure, the force-[Ca2+]irelationship was identical to control, such that ANP produced relaxation solely by decreasing [Ca2+]i. Thus, during muscarinic stimulation, stimulation of pGC relaxes ASM exclusively by decreasing [Ca2+]i, whereas stimulation of sGC decreases both [Ca2+]iand Ca2+sensitivity.
Impaired pulmonary artery contractile responses in a rat model of microgravity: role of nitric oxide
Authors: Nyhan Daniel , Kim Soonyul , Dunbar Stacey , Li Dechun , Shoukas Artin , Berkowitz Dan E.
Published: December 2017

Vascular contractile hyporesponsiveness is an important mechanism underlying orthostatic intolerance after microgravity. Baroreceptor reflexes can modulate both pulmonary resistance and capacitance function and thus cardiac output. We hypothesized, therefore, that pulmonary vasoreactivity is impaired in the hindlimb-unweighted (HLU) rat model of microgravity. Pulmonary artery (PA) contractile responses to phenylephrine (PE) and U-46619 (U4) were significantly decreased in the PAs from HLU vs. control (C) animals. N G-nitro-l-arginine methyl ester (10−5 M) enhanced the contractile responses in the PA rings from both C and HLU animals and completely abolished the differential responses to PE and U4 in HLU vs. C animals. Vasorelaxant responses to ACh were significantly enhanced in PA rings from HLU rats compared with C. Moreover, vasorelaxant responses to sodium nitroprusside were also significantly enhanced. Endothelial nitric oxide synthase (eNOS) and soluble guanlyl cyclase expression were significantly enhanced in PA and lung tissue from HLU rats. In marked contrast, the expression of inducible nitric oxide synthase was unchanged in lung tissue. These data support the hypothesis that vascular contractile responsiveness is attenuated in PAs from HLU rats and that this hyporesponsiveness is due at least in part to increased nitric oxide synthase activity resulting from enhanced eNOS expression. These findings may have important implications for blood volume distribution and attenuated stroke volume responses to orthostatic stress after microgravity exposure.
Subfailure damage in ligament: a structural and cellular evaluation
Authors: Provenzano Paolo P. , Heisey Dennis , Hayashi Kei , Lakes Roderic , Vanderby Ray
Published: December 2017

Subfailure damage in ligaments was evaluated macroscopically from a structural perspective (referring to the entire ligament as a structure) and microscopically from a cellular perspective. Freshly harvested rat medial collateral ligaments (MCLs) were used as a model in ex vivo experiments. Ligaments were preloaded with 0.1 N to establish a consistent point of reference for length (and strain) measurements. Ligament structural damage was characterized by nonrecoverable difference in tissue length after a subfailure stretch. The tissue's mechanical properties (via stress vs. strain curves measured from a preloaded state) after a single subfailure stretch were also evaluated ( n = 6 pairs with a different stretch magnitude applied to each stretched ligament). Regions containing necrotic cells were used to characterize cellular damage after a single stretch. It should be noted that the number of damaged cells was not quantified and the difference between cellular area and area of fluorescence is not known. Structural and cellular damage were represented and compared as functions of subfailure MCL strains. Statistical analysis indicated that the onset of structural damage occurs at 5.14% strain (referenced from a preloaded length). Subfailure strains above the damage threshold changed the shape of the MCL stress-strain curve by elongating the toe region (i.e., increasing laxity) as well as decreasing the tangential modulus and ultimate stress. Cellular damage was induced at ligament strains significantly below the structural damage threshold. This cellular damage is likely to be part of the natural healing process in mildly sprained ligaments.

Published: December 2017

Phrenic nerve stimulation (PNS) can assess airflow dynamics of the upper airway (UA) during wakefulness in man. Using PNS, we aimed to assess the impact of neck flexion and mouth opening in promoting UA unstability. Measurements were made during nasal breathing in seven healthy subjects (ages = 23–39 yr; one woman). Surface diaphragm electromyogram, esophageal pressure referenced to mask pressure, and flow were recorded during diaphragm twitches with neck in neutral position and mouth closed and then with neck flexion and/or mouth opening. Twitches always exhibited a flow-limited pattern. Flow-limiting driving pressure (Pd) and peak Pd were increased by neck flexion ( P < 0.01) without significant change in the corresponding flows. UA resistances at these flow values were higher with the neck flexed ( P < 0.05). Mouth opening alone did not exert any significant influence. We conclude that the position of the neck has a discernible impact on the flow behavior through the nonphasically active UA faced with a negative Pd.
Expression of renal cell protein markers is dependent on initial mechanical culture conditions
Authors: Cowger Nancy L. , Benes Edmund , Allen Patricia L. , Hammond Timothy G.
Published: December 2017

The rotating wall vessel is optimized for suspension culture, with laminar flow and adequate nutrient delivery, but minimal shear. However, higher shears may occur in vivo. During rotating wall vessel cultivation of human renal cells, size and density of glass-coated microcarrier beads were changed to modulate initial shear. Renal-specific proteins were assayed after 2 days. Flow cytometry antibody binding analysis of vitamin D receptor demonstrated peak expression at intermediate shears, with 30% reduction outside this range. Activity of cathepsin C showed the inverse pattern, lowest at midshear, with twofold increases at either extreme. Dipeptidyl-peptidase IV had no shear dependence, suggesting that the other results are specific, not universal, changes in membrane trafficking or protein synthesis. On addition of dextran, which changes medium density and viscosity but not shear, vitamin D receptor assay showed no differences from controls. Neither cell cycle, apoptosis/necrosis indexes, nor lactate dehydrogenase release varied between experiments, confirming that the changes are primary, not secondary to cell cycling or membrane damage. This study provides direct evidence that mechanical culture conditions modulate protein expression in suspension culture.

Published: December 2017

Background/Aims: Diabetes-related dementia (DrD), a dementia subgroup associated with specific diabetes mellitus (DM)-related metabolic abnormalities, is clinically and pathophysiologically different from Alzheimer disease (AD) and vascular dementia. We determined whether skeletal muscle strength, quality, and mass decrease in individuals with DrD. Methods: We evaluated grip and knee extension strength, muscle mass, and gait speed in 106 patients with probable AD and without type 2 DM (AD[–DM] group), 74 patients with probable AD and with DM (AD[+DM] group), and 36 patients with DrD (DrD group). Muscle quality was defined as the ratio of muscle strength to muscle mass. Results: Both female and male subjects with DrD showed significantly decreased muscle strength and quality in the upper extremities compared with the subjects with AD[–DM] or AD[+DM]. Female subjects with DrD showed significantly decreased muscle quality in the lower extremities compared with the subjects with AD[–DM]. Both female and male subjects with DrD had a significantly lower gait speed compared with the subjects with AD[–DM]. However, there were no significant differences in muscle mass and the prevalence of sarcopenia between the groups. Conclusion: Subjects with DrD showed decreased muscle strength and quality, but not muscle mass, and had a low gait speed.
An Unexpected Case of Scurvy in a Peritoneal Dialysis Patient
Authors: El Khoury Raymonda , Warren Mitchell , Ali Saba , Pirkle Jr. James L.
Published: December 2017

This case describes an obese adult male peritoneal dialysis patient who presented with a pruritic follicular rash. Nutrient deficiency was not suspected initially in this case because there was no history of protein-calorie malnutrition, but the patient reported a diet devoid of fruits and vegetables and had not been taking his dialysis vitamin as prescribed. Skin biopsy showed follicular hyperkeratosis with fragmented hair shafts and corkscrew hairs consistent with scurvy. After supplementation with ascorbic acid 500 mg twice daily for 2 weeks, the rash resolved completely. Dialysis patients are at increased risk for vitamin C deficiency due to indiscriminant clearance of the nutrient with dialysis, but scurvy is rarely seen.

Published: December 2017

Renal angiomyolipoma (AML), a rare benign mesenchymal neoplasm, is characterized by the presence of vessels, smooth muscle, and adipose tissue. Treatment should be considered for symptomatic patients or for those at risk for complications, in particular for retroperitoneal bleeding, which is correlated to the size of the tumor, grade of the angiogenic component, and presence of tuberous sclerosis complex. Herein, we report the case of a 39-year-old female with renal AML who was treated in a conservative approach by super-selective embolization.

Published: December 2017

Background: It is uncertain whether kidneys from marginal donors are suitable for live kidney transplantation. In deceased donor kidneys, tubular cell senescence affects allograft function. However, the degree of cell senescence in a living donor kidney with marginal factors has not been reported. In this study, we assessed the association of tubular cell senescence with allograft and remnant kidney function by a prospective observational clinical study. Methods: Thirty-eight living donor kidney transplantations were analyzed prospectively. Tissue sections obtained from preimplantation kidney biopsies were immunostained for p16INK4a to indicate cell senescence. Various kidney biomarkers were analyzed in urine and blood samples. Results: Of the 38 donors, 21 had marginal factors. Severe tubular senescence was found in living donors with overlapping marginal criteria. Tubular senescence in living donor kidneys was significantly related to donor age and lower recipient kidney function at 1 year after transplantation independently of donor age (β = –0.281; p = 0.050) but did not affect remnant kidney function after donation. Pretransplantation donor pre-estimated glomerular filtration rate and hypertension did not show a significant area under the curve (AUC) for prediction of high tubular senescence. High plasma levels of soluble αKlotho were associated with a higher predictive value for low tubular cell senescence with an AUC of 0.78 (95% CI 0.62–0.93; p < 0.01). Conclusions: The nuclear p16-staining rate in donated kidney tubules is a predictor for allograft kidney function but not donor remnant kidney function. Detection of tubular cell senescence may facilitate selection of appropriate living donor candidates.

Tracking the ancestral Portuguese name of the osprey across the Atlantic: hints from language, literature, history and geography
Authors: Palma Luís Manuel
Published: December 2017

Guincho, the traditional Portuguese name of the osprey (Pandion haliaetus) is unique and ancestral. It is found in several sorts of fictional literature from the 16th up to the early 20th centuries in the form of a metaphor born from an old popular proverb. The first time the name appears as the vernacular designation of the osprey is in a 17th falconry treatise, and then in old dictionaries and early ornithological monographs and catalogues throughout the 18th to early 20th centuries. In Portugal, however, the name barely survives, partly due to the species demise in the country during the 20th century, but mainly because it was gradually replaced by an erudite term in ornithological literature since the middle 19th century. However, given the conspicuousness of the species and its nests, the name and its composites are retained in a number of places along the coast. And, following the Portuguese diaspora of the 16th-18th centuries, the term spread to the archipelagos of Madeira, Cape Verde and the Canaries where it impregnated the local vocabulary and again gave the name to many coastal places. Then, it moved from the Canaries to the Spanish speaking areas of the Caribbean riding the mass migration of Canary Islanders to the new colonies. In consequence, the traditional Portuguese name of the osprey is still fully used in several island countries across the Atlantic. The remarkable presence of the ancestral Portuguese name of the osprey in language, literature and geography allows its rehabilitation as the proper popular name of the species and sanctions its legitimacy as a tool for reconstructing the ancient historical ranges of the osprey. Ultimately, revaluing the name is also a matter of cultural preservation, which compliments and enriches the current efforts for the species recovery in Portugal.

Quando o funk ostentação performa (re)existência: reflexões polissêmicas sobre contextos fronteiriços e experiências bastardizadas
Authors: Rezende Aline da Silva Borges
Published: December 2017

Este artigo busca problematizar e refletir sobre a noção de resistência na contemporaneidade, tendo em vista os circuitos culturais e contextos específicos de recepção do gênero musical do funk ostentação. Interessa-nos, neste percurso, explorar os agenciamentos e as potenciais formas de resistência articuladas pelos jovens periféricos que protagonizam esse circuito musical, bem como os modos de (re)existência mobilizados a partir do consumo das narrativas midiáticas da ostentação entre um grupo de crianças, moradoras da maior favela sobre palafitas do país. Valendo-se dos aportes teóricos dos estudos culturais, em confluência com as categorias conceituais de culturas bastardas, narrativas midiáticas e performatividade, corroboramos a construção de uma abordagem polissêmica sobre o fator resistência, sobretudo no tocante às manifestações do popular-periférico contemporâneo.

Trata-se de uma proposta que, voltada à qualificação da formação do professor enfermeiro e do aluno da EPTNM na área da saúde/enfermagem, pode promover a articulação universidade-escola técnica contribuindo com o fortalecimento do compromisso social da universidade com a educação e a saúde.
Reinventar Paris
Authors: Retto Junior Adalberto da Silva
Published: December 2017

A mostra Réinventer Paris, com os 23 dos 815 projetos que participaram da competição internacional lançada pela prefeita socialista Anne Hidalgo, demonstra o que, para alguns críticos, significa uma nova forma de abordar o desenvolvimento urbano. As intervenções ambiciosas escolhidas para reinventar a Paris do futuro são a prova clara do que realmente pode ocasionar mudança de ritmo, alteração nos caminhos para o desenvolvimento de uma cidade, tomando por base a capacidade de instalar um verdadeiro laboratório. Por trás dos projetos selecionados encontra-se uma escolha política bem clara, que parte de uma administração que é capaz de planejar o futuro (tanto em médio e longo prazo) e acima de tudo, sabe colocá-la no centro do debate entre o público de especialista e outros tipos de atores locais.
Resposta a Vilanova Artigas. Por uma sede própria.

Um dos atributos que fizeram do Edifício IAB um objeto singular é o modelo raro, senão único, de edificação do porte e tipologia erguida por e para seus usuários em favor de uma causa. Isso porque, em 1943, quando o Departamento Paulista do Instituto de Arquitetos do Brasil é instalado, institucionaliza-se uma agenda ímpar cujo mérito foi unir a classe por uma nova arquitetura a exemplo do grupo do Rio de Janeiro reconhecido internacionalmente. Todavia, o não aprofundamento acerca do papel desempenhado pela seção paulista do instituto, na implementação das tendências de vanguarda, está a comprometer o reconhecimento crítico da relação entre a sua fundação e a renovação da arquitetura produzida na cidade simbolizada no próprio edifício-sede inaugurado em 1950. Logo, identificar o ora nomeado Movimento IABsp e seus seguidores pode aprimorar os critérios de análise e crítica no campo da prática arquitetônica à época da gestão de Eduardo Kneese de Mello à frente do instituto (1943-1950). Nascido em resposta a Vilanova Artigas, que durante um ciclo de depoimentos questionou o anonimato de seus pares engajados na ação coletiva, este artigo não entra no mérito do objeto arquitetônico, propriamente dito, tombado pelo Instituto do Patrimônio Histórico e Artístico (IPHAN), em 2015.

As fórmulas e formas nominais de tratamento constituem um repertório linguístico aberto, seu uso depende de condicionantes tanto pragmáticos quanto sociais (Fontanella de Weinberg, 1999). Do ponto de vista sociolinguístico, variam em função de condicionantes de idade, escolaridade e sexo, bem como de variação dialetal. Do ponto de vista pragmático, variam em função do grau de proximidade ou hierarquia da relação, conhecimento compartilhado, grau de coloquialidade da interação e tipo de ato de fala que realizam. Neste trabalho, analisamos a variação na legendagem em português (brasileiro e europeu) e em espanhol (latino e ibérico) das diferentes versões do filme Inside Out: Divertida Mente, Divertida-mente, Intensamente e Del Revés. Comparamos as escolhas convergentes e divergentes de tradução do original em inglês no que diz respeito às fórmulas e formas nominais de tratamento, bem como, do ponto de vista conversacional, suas funções de intensificação ou atenuação de atos diretivos e expressivos nos diálogos. Os resultados de nossa análise assinalam que as formas nominais de tratamento são mantidas na legendagem em função dos seguintes condicionamentos conversacionais: (i) seleção do interlocutor e gestão dos turnos de fala; (ii) intensificação de atos de fala expressivos; (iii) marcas sociolinguísticas de relação interpessoal e (iv) indexador de identidade social.
Abordagem processual e ensino de tradução: uma proposta de unidade didática para o par espanhol-português baseada em dados de rastreamento ocular e registro de teclado e mouse
Authors: Malta Gleiton
Published: December 2017

Este artigo apresenta uma proposta de unidade didática baseada no enfoque por tarefas e em dados empíricos de processo tradutório capturados em tempo real por meio de equipamento de rastreamento ocular e programa de registro de teclado e mouse. Trata-se de uma pesquisa-ação que contempla dois ramos do campo disciplinar dos Estudos da Tradução: o descritivo e o aplicado. Com base nos dados empíricos, elaborou-se uma unidade didática cujo objetivo principal é a prática, docente e discente, da leitura para tradução, acentuando suas especificidades em cada fase do processo tradutório: orientação, redação e revisão (Jakobsen, 2002). Os resultados da experiência de aplicação da unidade proposta apontaram para o desenvolvimento de uma maior autonomia do estudante e maior consciência sobre seu processo. Para o docente/pesquisador, possibilitou o uso de uma ação sistemática, sequenciada e com objetivos e procedimentos específicos para a aula de tradução espanhol-português, além da unificação dos ramos descritivo e aplicado.

Proporcionar experiências educacionais que valorizem o protagonismo do estudante e integrem teoria e prática tem sido uma das principais dificuldades para os professores da educação superior e dos cursos de Relações Públicas no Brasil. Neste relato, é apresentado o projeto Conexão, desenvolvido na disciplina Teoria e História das Relações Públicas, com o objetivo de engajar os estudantes no processo de aprendizagem e dinamizar os significados dos conceitos estudados no decorrer do semestre. Como resultados, verificou-se a preferência pelas estratégias educacionais ativas, assim como o potencial motivador de projetos que incentivem os estudantes a interagirem e a produzirem estudos que extrapolem a sala de aula. O projeto é um exemplo de atividade didática que integra teoria e prática e pode contribuir para a reflexão de docentes e gestores de cursos preocupados com a melhoria dos processos educativos.

Na disciplina semestral e obrigatória: “MPR 0614 Sistemas, planejamento e gestão em saúde”, do Curso de Graduação de Medicina da Universidade de São Paulo, utilizou-se exercícios de fixação como instrumento de avaliação a fim de inserir estratégias que favorecessem a aprendizagem significativa dos alunos em via de realizar prova de residência médica. O objetivo deste relato de experiência foi descrever a apresentação e o impacto da técnica do exercício de fixação como estratégia de ensino de graduação. Para isso, dois pós-graduandos da USP, no papel de facilitadores do aprendizado, realizaram uma experiência de auxílio à relação professor-aluno em sala de aula, aprofundando os conteúdos teóricos e práticos necessários para a compreensão das dinâmicas de planejamento e gestão de serviços de saúde no âmbito de um sistema de saúde, sobretudo, no SUS. Como resultado, constatou-se o reconhecimento contributivo dos exercícios de fixação tanto por parte dos professores titulares e convidados quanto dos alunos do 6º ano de medicina da USP.

Recursos tecnológicos podem contribuir para o ensino da Anatomia Veterinária, tornando as disciplinas relativas a tal área, que são essenciais para a formação dos estudantes de Medicina Veterinária, cada vez mais atualizadas frente às novas tecnologias e às novas gerações de estudantes. Neste trabalho, o objetivo foi aplicar a digitalização e a impressão 3D para produzir biomodelos dos esqueletos canino e equino, de modo a disponibilizar as peças produzidas como ferramenta alternativa de estudo nas aulas práticas de anatomia veterinária. Ossos de cão e equino foram digitalizados, sendo possível realizar a sua impressão 3D com preservação eficaz das principais estruturas anatômicas. Por meio desse processo, também foi possível gerar arquivos digitais para que sejam utilizados durante as aulas práticas. Além disso, os biomodelos e os arquivos digitais produzidos poderão ser aplicados como uma forma alternativa e complementar para o estudo anatômico do esqueleto canino e equino.

Este estudo foi destinado para realizar uma análise detalhada da dinâmica espaço-temporal dos padrões do uso e cobertura da terra em dez sub-bacias hidrográficas localizadas no Baixo Curso do Rio Itapecuru, no Estado do Maranhão.  A avaliação foi processada por meio do mapeamento de imagens Landsat-5 Thematic Mapper, referentes aos anos de 2005, 2010 e 2015, que foram adquiridas gratuitamente junto ao Instituto Nacional de Pesquisas Espaciais – INPE. Para o mapeamento, foram utilizadas as seguintes classes de UCT: ocupação (alta, média e baixa), vegetação (alta, média, baixa), solo exposto, agricultura, campo inundável e água continental. Os resultados mostraram que as classes “vegetação alta” e “vegetação média” foram predominantes nos três anos analisados. As principais mudanças foram evidenciadas nas SBHs 1, 2 e 10. Nas SBHs 1 e 2, foram impulsionadas pela supressão da vegetação durante a etapa de terraplenagem de empreendimento petroquímico localizado no Município de Bacabeira, enquanto que, na SBH-10, o principal agente modificador foi a expansão das áreas ocupadas da cidade de Rosário. No entanto, num cenário futuro, existe a possibilidade da chegada de novos empreendimentos na região do BCRI, os quais, irão potencializar a pressão sobre os recursos naturais das demais SBHs, com a real possibilidade de ocorrerem mudanças significativa nos padrões de paisagem, gerando consequências negativas sobre a qualidade de vida das comunidades locais e funcionamento dos ecossistemas naturais. As informações obtidas sugerem o estabelecimento de estratégias de gerenciamento ambiental que antecipem a chegada de futuros empreendimentos, considerando a capacidade de suporte do ambiente e compatibilizando sua implantação com a manutenção das características socioambientais inerentes ao BCRI
Marital Satisfaction among Korean Commuter Couples
Authors: Lee Yun-Suk
Published: December 2017

In Korea, some dual-earner married couples, where both husbands and wives have careers, live separately because their workplaces are located too far for a daily commute. These “commuter couples” are on the rise all over the world. In general, physical closeness is important for the quality of the relationships; thus, marital satisfaction is one of the most important issues in the literature on commuter couples. While some studies found a lower quality of relationships among commuter couples, others found cohesive and trustful relationships in these couples. However, the existing studies were conducted mainly with convenience samples of specific occupational groups in developed countries. Using a recent representative sample of commuter couples in Korea, this study found that commuter couples report lower levels of marital satisfaction compared to typical dual-earner couples. Additionally, this study found that in commuter couples, wives feel less marital satisfaction compared to their husbands.
