ABSTRACT Introduction Monitoring training loads, along with the recovery status, is important for preventing unwanted adaptations. Knowledge of these variables over volleyball seasons is still scarce. Objective To monitor and describe the training load and recovery status of volleyball players over a competitive season. Methods The sample consisted of 14 professional volleyball players. For the entire season, the training load was monitored daily by the SPE method during the session, and the recovery status was monitored by TQR and QBE on the first and last days of training for the week. Results There was a decrease in training load between Preparatory Period I and Competitive Period I (p = 0.03), followed by an increase in Preparatory Period II (p <0.001) and a new decrease in Competitive Periods II (p = 0.01 ) and III (p = 0.003). There was a significant reduction between Pre-TQR and QBE and Post-TQR and QBE in all mesocycles. In the Pre-TQR, there was a reduction between Preparatory Period II and Competitive Period II (p = 0.006), in the Pre-QBE, there was a reduction between Preparatory Period II and Competitive Period III (p = 0.002), and in the Post-TQR, this reduction was observed between Competitive Period I and Preparatory Period II (p = 0.03). In the Post-QBE, there was an increase between Preparatory Period I and Competitive Period I (p = 0.002), followed by a decrease in Preparatory Period II (p = 0.01). Conclusion Loads varied throughout the season, along with recovery, which varied according to the loads and characteristics of each period.

RESUMO O objetivo do presente trabalho foi determinar e comparar o perfil metabólico de vacas Holandês (H) e mestiças Holandês x Jersey (HxJ) no periparto. Avaliaram-se 24 vacas, sendo 11 vacas Holandês e 13 mestiças Holandês x Jersey. Semanalmente, coletou-se sangue para a determinação das concentrações séricas de glicose, beta-hidroxibutirato (BHB), proteína total, albumina, aspartato aminotransferase (AST), creatinoquinase (CK), cálcio total, cálcio iônico, magnésio, fósforo inorgânico e colesterol. Avaliou-se também o peso vivo e o escore de condição corporal (ECC). Os dados foram submetidos à análise de variância com medidas repetidas no tempo. As vacas Holandês apresentaram maior peso vivo. Não houve diferença entre os grupamentos genéticos para ECC. Foi observada tendência de maiores concentrações séricas de BHB, AST e maior concentração de cálcio iônico em vacas mestiças Holandês x Jersey. Vacas mestiças Holandês x Jersey e Holandês apresentaram perfil energético similar durante o período de transição pré e pós-parto na maioria dos indicadores, com exceção do cálcio, que foi maior nas vacas mestiças, e do fósforo, que foi superior nas vacas Holandês.

ABSTRACT The study evaluated the effect of transportation over long distances on cattle muscle tissue of submitted to emergency slaughter in slaughterhouses in northern Tocantins, Brazil. The evaluations consisted in pH, muscle and liver glycogen, muscle histopathology and creatine kinase (CK), alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activity. Animals were placed into two groups: Experimental Group (EG), consisting of 19 bovines intended for immediate emergency slaughter, and Control Group (CG), composed of 24 bovines slaughtered in accordance with the normal flow. CK and ALT levels were high in EG. AST did not differ between groups. EG showed higher muscle pH and mean of degenerate fibers, mainly on the intercostal. However, muscle and liver glycogen did not differ between groups. In conclusion, cattle transported over long distances and subjected to immediate emergency slaughter showed markedly stress condition, with changes in biochemical parameters in the muscle tissue, determined by cellular degeneration.

ABSTRACT Piau porcine blastocysts were submitted to MALDI-TOF to identify the main phospholipids (PL). After that, in vivo blastocysts (D6) were vitrified (n=52), non-vitrified were used as control (n=42). After warming, blastocysts were in vitro cultured to assess re-expansion and hatching at 24 and 48 hours. Finally, at 48 hours, hatched blastocysts were submitted to RT-qPCR searching for BCL2A1, BAK, BAX and CASP3 genes. For MALDI-TOF, the ion intensity was expressed in arbitrary units. Blastocyst development was compared by Qui-square (P< 0.05). Among the most representative PL was the phosphatidylcholine [PC (32:0) + H]+; [PC (34:1) + H]+ and [PC (36:4) + H]+. Beyond the PL, MALDI revealed some triglycerides (TG), including PPL (50:2) + Na+, PPO (50:1) + Na+, PLO (52:3) + Na+ and POO (52:2) + Na. Re-expansion did not differ (P> 0.05) between fresh or vitrified blastocysts at 24 (33.3%; 32.7%) or 48 hours (2.4%; 13.5%). Hatching rates were higher (P< 0.05) for fresh compared to vitrified at 24 (66.7%; 15.4%) and 48 hours (97.6%; 36.0%). BAX was overexpressed (P< 0.05) after vitrification. In conclusion, Piau blastocysts can be cryopreserved by Cryotop. This study also demonstrated that the apoptotic pathway may be responsible for the low efficiency of porcine embryo cryopreservation.

ABSTRACT Retrocaval ureter (RU) is an abnormal embryonic development of the caudal vena cava (CVC) that leads the ureter to be entrapped dorsal to the CVC. In most cases there is no clinical impact; however, it can cause hydronephrosis. We report a rare case of type II symptomatic retrocaval ureter in a feline treated with nephroureterectomy. A 4-year-old, intact male, mixed breed cat was submitted to abdominal ultrasound and severe right hydronephrosis was diagnosed, with no signs of obstruction. We performed an exploratory celiotomy, in which a displacement of the right ureter dorsal to the CVC was observed. The animal was treated with ureteronephrectomy and recovered well. No intraluminal cause was found, and a urethral catheter could be easily inserted across the ureter length. The real clinical relevance of the RU is unknown, since it is a common find in post-mortem examination without kidney impact and, when significant, is often associated to other causes of ureteral obstructions, such as calculi and strictures. Additionally, in humans, type II RU seldom develops obstruction and hydronephrosis. In our case, due to absence of other causes of obstruction, probably mechanical compression of the CVC against the psoas muscle caused the hydronephrosis.

Published: July 2019

ABSTRACT Portosystemic shunt (PSS) is an anomalous vascular connection between the portal venous system and the systemic circulation. These deviations connect the main portal vein (PV) or some portal branches to the vena cava (VC) or, less commonly, to the azygos vein (AV). The purpose of this case report was to describe the diagnosis of PSS in a dog classified as porto-azygos. This diagnosis is considered uncommon compared to other portosystemic shunts using ultrasonography and portography. The subject was a male dog, Yorkshire, 8 months old, presented neurological signs characterized by head press, ataxia, tremors and episodes of temporary blindness and deafness. Ultrasonographic examination revealed a dilated and curved anomalous vessel with approximately 0.6cm of diameter and turbulent flow seen through pulsed and color Doppler, and segmental dilation of the azygos vein. The portography revealed enhancement by iodinated contrast in the jejunal vein, the portal vein and an anomalous vessel flowing towards the azygos vein in the craniodorsal region of the abdomen. The PSS was surgically corrected with an ameroid constrictor. Ultrasonography and portography were effective at detecting and characterizing the portoazygos shunt despite some limitations.

ABSTRACT Trauma or disease inflicted by tissue injuries may cause tissue degeneration. The use of biomaterials for direct or indirect repair has emerged as a promising alternative, and has become an important research topic. The pequi fruit (Caryocar brasiliense Camb.) has shown antifungal, antibacterial, anti-inflammatory, healing, antitumor, and antioxidant properties. The objective of this study was to develop a new biomaterial using a combination of collagen, gelatin, and pulp pequi oil, and to evaluate its biocompatibility in comparison with that of biomaterials produced without pulp pequi oil. Membranes were prepared from a mixture of bovine tendon collagen, commercial gelatin, and pulp pequi oil. The inflammatory and cicatricial processes were assessed via histopathology of the tissue interface/implants in the subcutaneous tissues and quantitative evaluation of leukocyte and collagen production in Wistar rats. It was observed that the presence of pequi oil reduced the amount of foreign-body giant cells and favored the recruitment of fibroblasts (P< 0.01), thereby promoting greater production of collagen membrane than that in the membranes of control samples. Therefore, it can be concluded that the addition of pequi oil improved the biocompatibility of collagen and accelerated the healing process.

RESUMO Determinaram-se os valores de temperatura do ar, umidade relativa e índice de temperatura e umidade (ITU) de uma propriedade rural de produção de leite a pasto e da estação meteorológica oficial mais próxima, confrontando-os. Na fazenda, as leituras dos dados foram registradas por uma estação meteorológica automática, a cada cinco minutos, de fevereiro de 2015 a setembro de 2016. Depois, calcularam-se a média por hora e o ITU horário. Selecionaram-se os valores diários mínimo, médio e máximo. O mesmo foi feito com os dados da estação meteorológica oficial, que foram horários. As temperaturas mínima e média na estação meteorológica foram maiores que na fazenda durante todo o período experimental e em 16 meses, respectivamente. A temperatura máxima da propriedade rural foi maior que a da estação em seis meses. Já a umidade relativa mínima, a média e a máxima da estação meteorológica foram inferiores às da fazenda. O ITU mínimo foi maior na estação oficial e o ITU máximo superior na fazenda em todos os meses. Por fim, o número de dias com um ITU máximo igual ou superior ao ITU crítico foi maior na fazenda. Assim, dados da estação meteorológica oficial subestimam o estresse por calor.

ABSTRACT In this essay, we quantify the concentration of collagen fibers in broiler chickens exposed to increasing concentrations of cupuacu seed by-product. Collection of material was carried out in five chickens per treatment at 70 days old in the groups: control, 5% and 10% inclusion of cupuacu seed by-product. Fragments of Thoracic Pectoralis (PT) and Iliotibial lateralis (ITL) muscles were prepared for light and electronic microscopy. The amount of collagen fibers in the muscle groups was 1.08±0.61% in the PTC group; 6.24±2.58% in PT5% and 7.30±2.75% in PT10%. In the Iliotibial Lateralis groups, the results were 6.96±3.14% in the ITLC; 7.43±4.22% in the ITL5% and 8.66±2.35% in ITL10%. The amount of collagen fibers in the ITL5% and ITL10% groups showed no significant statistical difference. However, when compared to the ILTC group, there was a significant statistical difference. The PT muscle responds to standard nutritional changes, unlike the ILT muscle, which requires a high-nutrient formulation. The use of 5% cupuacu seed by-product has proven to be a viable alternative source of animal feed, as it promotes an increase in the concentrations of collagen fibers in the musculature of broiler chickens and is possibly the determining factor in meat texture.

RESUMO A suplementação proteico-energética (SPE) é uma estratégia adequada à bovinocultura de corte no período seco do ano, embora sua adoção equivocada possa comprometer seu benefício/custo. O objetivo deste estudo foi avaliar o desempenho de novilhas Nelore em pastagem diferida de Urochloa decumbens sob dois períodos de SPE, e realizar análise econômica desses sistemas de produção. O experimento foi conduzido sob delineamento inteiramente ao acaso, com 147 e 55 dias de SPE (sistemas 1 e 2, respectivamente), de 21/06 a 15/11/2016, com 16 e 20 novilhas nos sistemas 1 e 2, respectivamente. Os dados de desempenho foram analisados utilizando-se o PROC MIXED do SAS®, e as médias comparadas por PDIFF (P<0,05). Os pesos médios foram semelhantes (P>0,05) entre os sistemas de produção nas pesagens de 21/06, 12/07, 02/08, 23/08 e 15/11/2016. Os valores presentes líquidos foram positivos sob a taxa anual de desconto de 4%, sendo viáveis financeiramente. Por apresentarem taxa interna de retorno superior à taxa mínima de atratividade, os sistemas foram atrativos para investimento. Foi obtido balanço econômico positivo de R$ 25,26/animal para substituição do sistema 1 pelo sistema 2. A redução de 92 dias na SPE proporciona desempenho semelhante entre novilhas e maior eficiência econômica do sistema de produção.

ABSTRACT A 3 year old female feline of mixed breed was sent to the diagnostic imaging sector under suspicion of bleeding due to ovariohysterectomy. An abdominal ultrasonography was performed to confirm the initial suspicion. However, no signs of bleeding were found, instead it was observed that the left renal silhouette had two pelvises and was elongated and larger than normal. The right kidney was not found. Excretory urography was requested to evaluate the condition of the ureters. The final diagnosis was crossed renal ectopia with fusion in an asymptomatic cat with no changes in renal function.

RESUMO Avaliou-se a influência da somatotropina recombinante bovina (rbST) sobre os metabolismos energético e mineral de búfalas entre 63e 154 dias em lactação. Foram utilizadas 22 búfalas, distribuídas em dois grupos experimentais: grupo rbST - aplicação de 500mg de rbST a cada 14 dias; grupo Controle - sem aplicação de rbST. A cada sete dias, foram coletadas amostras de sangue para a determinação do perfil bioquímico e mensuraram-se a produção de leite e o escore de condição corporal dos animais. As médias dos parâmetros estudados para os grupos rbST e Controle foram, respectivamente: produção de leite (PL): 6,44kg vs. 6,68kg; escore de condição corporal-ECC (1-5): 3,51 vs. 3,57; glicose: 70,58 vs. 64,81mg/dL (P = 0,0003); colesterol: 132,38 vs. 133,40mg/dL; triglicérides: 29,18 vs. 28,32mg/dL; proteína total: 8,57 vs. 8,75g/dL; albumina: 3,47 vs. 3,60g/dL; ureia: 32,46 vs. 33,86mg/dL; creatinina: 1,27 vs. 1,39mg/dL; cálcio:10,25 vs. 10,73mg/dL; fósforo:5,76 vs. 5,62mg/dL; e magnésio:3,70 vs. 3,70mg/dL. O uso de 500mg de rbSTinfluenciou o metabolismo da glicose, porém não modificou a PL, o ECC e os níveis dos demais parâmetros metabólicos estudados.

ABSTRACT Alveolar macrophages (AMs) are an essential part of defense mechanisms within the lungs and their phagocytic activity is important for organ homeostasis. The phagocytic ability of AMs obtained from bronchoalveolar lavage from 17 mature mixed-breed pleasure horses (8 healthy and 9 diagnosed with mild equine asthma) was studied through assays with Leishmania (Viannia) braziliensis promastigotes, which enabled the calculation of a phagocytic index (PI) and a survival index (SI). Results indicate that phagocytic activity of AMs in asthma affected horses is similar to healthy horses, while leishmanicidal activity is significantly increased in horses with asthma.

Published: July 2019

ABSTRACT The objective of this study was to determine the frequency of different categories of specific and general classification in canine cavitary effusions (CE), as well as their association with the underlying etiologies. The laboratorial and clinical data from 304 cases of canine CE were retrospectively assessed. In 32.9% (100 cases), at least one of the specific classification categories was established, with a subtotal predominance of neoplasia (42%), bacterial serositis (24%) and hemorrhage (16%). Neoplasia was confirmed by effusion cytology in 57.5% of the cases with histopathological confirmation. From the cases in which the specific classification was not obtained, 35.8% were classified as modified transudate, 30.4% as pure transudate, 21.1% % as exudate and 12.7% was not included in any general category. The most common causes of effusion among these cases were hypoproteinemia and/or hipoalbuminemia (HPHA) (25.8%), hepatopathy (22.5%), cardiac insufficiency (15.5%) and cytologically undetected cases of neoplasia (12.4%). In conclusion, HPHA, hepatopathy and neoplasia represents important etiologies for canine CE development. Classification of effusions, solely based on [TP] and TNCC, might be an inaccurate diagnostic tool of effusions. New laboratorial classification methods for canine CE should be researched.

ABSTRACT The objective with this study was to evaluate the effect of different levels of water inclusion on the chemical composition and fermentation profiles of reconstituted corn grain silage. The experiment was carried out in a factorial arrangement in a completely randomized design, with three replicates per treatment. Five treatments were evaluated with different levels of water inclusion (% of the natural matter): dry corn grain (control); 90% dry corn grain (DCG) and 10% water; 80% DCG and 20% water; 70% DGC and 30% water; and 60% DCG and 40% water, totaling 45 experimental silos. Inclusion of water in the silage of reconstituted corn grain promoted a reduction in the CP (%) and NDF (%) contents. However, the water increase elevated the NPN/TN contents and the amount of effluent, gas and dry matter (%) losses. The treatment with inclusion of 30% water in the natural matter leads to a better fermentation profile and fewer losses of effluent and dry matter, so it is recommended for ensiling dry ground corn grain.

ABSTRACT: Pelvis is an osteoligamentous complex, which is classified as dolichopellic in ruminants. Impairments linked to incompatibility of pelvic canal and fetal size is directly related to pelvic anatomy and disposition. Heritability of pelvic area characteristics varies from moderate to high, demonstrating its importance for animal selection. Pelvimetry can be performed through direct and indirect methods that were accessed in this study aiming to establish a correlation between internal and external pelvic dimensions in multiparous Nellore cows (26 animals) at cycling and early puerperal (up to 30 days postpartum) reproductive stages. Pelvic dimensions measured by descriptive analysis were higher at early puerperal stage. Strong Pearson’s correlation was determined between internal and external pelvic dimensions, between reproductive stages, and between pelvic girdle area and internal pelvic area. Significant Tukey’s test differences between animals in internal and external dimensions were also found. According to the results, the pelvic anatomy of Nellore cows varies according to their reproductive stage. We detach that and provide data regarding the use of internal pelvic area for animal selection studies on this breed is determined and should be measured using the proposed formula, since it can confirm statistical differences in the areas of pelvic components between animals in the cycling and early puerperal stages.

ABSTRACT: Bovine mastitis is the most frequent disease worldwide in dairy herds, causing high economic losses to producers and industry, as well as having implications for public health due to the zoonotic potential of some agents involved in its etiology and the increased risk of antimicrobial residues in milk and its derivatives. Considering the multifactorial aspect of this disease, knowledge of the agents involved in its etiology and their antimicrobial susceptibility profiles is very important. This study was conducted with 306 dairy herds from the Campo das Vertentes region, located in the south of Minas Gerais state, whose owners were milk suppliers to a dairy in the same region. The study involved approximately 34,000 dairy cows and covered an area of approximately 12,564 km2. In these herds, prevalence rates of Staphylococcus aureus and Streptococcus agalactiae and their relationship with bulk milk somatic cell counts (BMSCC), total bacterial counts (TBC), and daily production were evaluated. In addition, analyses of resistance of these pathogens to the antimicrobials most commonly used in the treatment of mastitis in dairy herds were performed. Microbiological analyses of milk samples from collect from bulk milk tanks were performed aiming to evaluate the prevalence of S. aureus and S. agalactiae. For these proposes, the modified Baird-Parker Agar medium was used for detection of S. aureus and the modified Edwards Agar medium, enriched with 5% defibrinated sheep blood, was used for detection of S. agalactiae. The disc diffusion technique was applied to evaluate antimicrobial resistance. Results show high prevalence rates of S. aureus (70.3%) and S. agalactiae (67.0%) in the dairy farms studied, with 47.71% of the herds showing both pathogens. Associations between BMSCC and the presence of pathogens S. aureus and S. agalactiae and between TBC and the presence of S. agalactiae were observed, demonstrating the influence of these pathogens in milk quality. No variation was observed in the distribution of S. aureus and S. agalactiae in the different strata of daily production. High levels of resistance and multi-resistance were observed among the pathogens S. aureus and S. agalactiae. The results indicate the need for more effective control measures for mastitis caused by S. aureus and S. agalactiae in the dairy herds of the region studied and more judicious use of antimicrobials in order to reduce the problem of resistance to them.

ABSTRACT: Listeriosis is a disease that affects several animal species, including humans, and has three different forms of presentation: encephalic, reproductive, or septicemic. The nervous form is caused mainly by the bacterium Listeria monocytogenes. In Brazil, this disease has already been described in sheep, goats, and cattle. There are no reports of the disease in buffaloes in Brazil and worldwide. The objective of this study was to describe an outbreak of listeric meningoencephalitis in buffaloes in the state of Pará, Brazil. The outbreak occurred in a property located in the municipality of Bujaru, in the eastern Amazon, from May to July 2016. In a herd of 47 buffaloes, three animals (Cases 1, 2 and 3), aged <40 days, presented a neurological condition with locomotion difficulty characterized by paralysis of the four limbs, hypoesthesia, lateral recumbency, and death. Morbidity was 6.38% and lethality was 100%. At necropsy, no significant macroscopic lesions were found. Samples of the central nervous system were collected, fixed in 10% buffered formalin, and routinely processed for histopathological analysis. The main microscopic changes observed were unilateral microabscesses in the brainstem composed predominantly of mononuclear cells, with fewer polymorphonuclear cells, and perivascular cuffs composed mostly of mononuclear cells and few neutrophils. Samples of Cases 1 and 2 revealed Gram-positive bacteria in the areas of necrosis by the Gram’s stain technique. Samples of Case 1 were positive in immunohistochemistry for L. monocytogenes. Diagnosis of the nervous form of listeriosis was based on epidemiological data, clinical profile, and immunostaining for Listeria monocytogenes. Results showed that listeriosis should be considered in the differential diagnosis in buffaloes with nervous signs.

ABSTRACT: Knowledge about reproduction of white-lipped peccary is of great importance to assist with the conservation of this species and enable its rational use in captivity. This study aimed to evaluate the effect of ACP-103®, ACP-116® and BTS semen extenders on sperm viability during cooling of Tayassu pecari semen. Five ejaculates from four adult males were chilled. The animals were submitted to the protocols of sedation and anesthesia for semen collection by the electroejaculation method. After collection, the semen was macro- and microscopically assessed and diluted to reach 35x106 spermatozoa/mL in each of the three different extenders tested. The fresh-extended semen was packed in a BotuFLEX® thermal box to keep samples at 15°C for 24 hours. After cooling, the following semen parameters were analyzed: sperm motility, functional and structural integrity of sperm membranes, mitochondrial activity, chromatin condensation, and the thermoresistance test was performed. The parameters sperm motility, structural and functional integrity of sperm membranes, mitochondrial activity, and chromatin condensation were preserved after use of the extenders tested, and were similar to those of in natura semen (p>0.05). Curvilinear velocity (VCL) (p<0.05) was the only parameter with reduced values after cooling regardless of the extender used. The percentage of sperm with normal morphology was greater in samples cooled using the BTS extender (p<0.05). The ACP-103®, ACP-116® and BTS extenders can be used for the cooling and preservation of white-lipped peccary semen at 15°C for 24 hours.

ABSTRACT Cactus pear is adapted to semi-arid conditions. In this study, the objective was to evaluate the water use efficiency and green and dry mass yields of the cultivar Gigante under different fertilization rates and sources in three production cycles, spacing and planting arrangement. Seventy two treatments, involving two types of arrangements in the plots, three spacings in the subplots and 12 types of fertilization in the sub-subplots were arranged in a split-split-plot scheme, using randomized block design with three repetions. Dry mass content decreases while water use efficiency and green mass and dry mass yields increase from the first to the third cycle. It is feasible to use planting arrangements in triple or quadrupling rows which allow increasing the mechanization index of the crop. Organomineral fertilization with 30 or 60 Mg ha-1 year-1 of bovine manure combined with 150-300-600 kg ha-1 year-1 of N-P2O5-K2O and 300-300 kg ha-1 year-1 of P2O5-K2O, respectively; organic fertilization with 90 Mg ha-1 year-1 of manure; and mineral fertilization with 300-300-600 kg ha-1 year-1 of N-P2O5-K2O ensure green mass and dry mass yields greater than 200 and 15 Mg ha-1 cycle-1, respectively, and water use efficiency greater than 20 kg ha-1 mm-1 in ‘Gigante’ cactus pear. It is concluded that yields of this magnitude are ensured with application of about 300-300-300 kg ha-1 year-1 of N-P2O5-K2O using organic, organomineral or mineral sources.

ABSTRACT The boundary line technique has been proposed for interpreting biological data where one variable is a biological response and the other is an independent variable. The objective of this study was to correlate maize and soybean emergence parameters with soil seedbed physical properties using a boundary line approach. The study was performed at the experimental farm belonging to the Universidade Estadual de Ponta Grossa, in the municipality of Ponta Grossa, Paraná State, Brazil. The area has been managed under a no-tillage system for 18 years. The emergence percentage (EP) and emergence rate (ER) were determined for maize and soybean crops. Soil seedbed physical properties were evaluated for both crop species and included soil penetration resistance, volumetric water content, aggregate stability, tensile strength, friability, saturated soil hydraulic conductivity, bulk density, and the least limiting water range. The boundary line approach was applied to pairs of values of plant emergence parameters and soil seedbed physical properties, and then the regression model was adjusted to the boundary points. The boundary line approach indicated that crop emergence was dependent on soil seedbed physical properties. It was possible to determine the optimum values of soil seedbed physical variables for crop emergence. The boundary line approach is a promising and complementary tool to better understand crop emergence responses to soil seedbed physical properties.
USINA: ARTICULAÇÕES ENTRE ENSINO, LITERATURA E INTERAÇÕES ENTRE CIÊNCIA, TECNOLOGIA E SOCIEDADE

Published: July 2019

RESUMO: Nesse artigo se apresenta a análise da obra literária Usina do autor brasileiro José Lins do Rego, a fim de identificar a sua potencialidade para abordagens de interações entre Ciência, Tecnologia e Sociedade (CTS) no ensino de ciências da natureza. O livro foi submetido aos procedimentos da Análise Textual Discursiva (ATD). A análise foi organizada a partir de três categorias a priori e uma emergente: a visão salvacionista da ciência e da tecnologia e sua contradição; determinismo tecnológico; tecnocracia; e a relação entre cultura e tecnologia. Dentre os resultados podemos destacar que o livro Usina pode colaborar para: problematizar mitos relacionados ao desenvolvimento científico e tecnológico, de modo a favorecer o questionamento do otimismo e do pessimismo relacionado a ele; fomentar debates sobre a tomada de decisão no que concerne à tecnologia e seus impactos; e discutir como o desenvolvimento científico e tecnológico influencia as culturas.
Obesidade: possibilidades de existir e práticas de cuidado
Authors: Araujo Flávia Maria , González Alberto Durán , Silva Lucia Cecilia da , Garanhani Mara Lúcia
Published: July 2019

Resumo A obesidade apresenta origem multifatorial e é bastante frequente no Brasil. Hábitos alimentares podem refletir conflitos psíquicos que influenciam diretamente as práticas de cuidado, especialmente a dieta e a atividade física. A obesidade expressa formas de ser; segundo Merleau-Ponty, por meio do corpo, o homem vivencia o mundo - o corpo carrega valores e percepções. Com o objetivo de compreender quais comportamentos são vividos como cuidado pelas pessoas obesas e quais são as implicações disso para a prática profissional em saúde, realizamos uma pesquisa qualitativa com pessoas obesas em grau I e II, sete homens e cinco mulheres. Foram realizadas entrevistas que foram gravadas, transcritas e posteriormente analisadas por meio da análise do discurso. Os resultados foram divididos em três categorias: (1) tomada de decisão em cuidar-se ou não, revelando o momento de iniciar o cuidado e os fatores que influenciam essa decisão; (2) vivência das formas de cuidado, revelando possibilidades e dificuldades encontradas na execução do cuidado; e (3) emagrecimento como opção ou obrigação, questionando motivações para cuidar-se pela saúde ou atender a padrões estéticos. Concluímos que existem várias possibilidades de cuidado e vivência da obesidade; também observamos a necessidade de abordagens que compreendam as particularidades desse fenômeno.
PNAISH: uma análise de sua dimensão educativa na perspectiva de gênero
Authors: Pereira Jamile , Klein Carin , Meyer Dagmar Estermann
Published: July 2019

Resumo O artigo desdobra-se de pesquisa documental inscrita nos campos dos estudos de gênero e culturais e discute alguns dos modos pelos quais o gênero atravessa as proposições da Política Nacional de Atenção Integral da Saúde do Homem (PNAISH). Para isso, toma como referência um contexto discursivo em que termos como integralidade e equidade são reiteradamente apresentados e acionados, na direção de instituir propostas educativas e de cuidado voltadas à saúde e à educação de homens adultos. Argumentamos que, ao mesmo tempo em que essa amplitude coloca sob suspeita determinadas formas de viver a masculinidade, ela não desloca a centralidade dos processos curativos e parece contribuir para impregnar a política com uma visão utilitária, individualizando e culpabilizando os homens por seu distanciamento dos serviços de saúde.

Resumen El objetivo de esta investigación fue comprender las representaciones sociales asociadas al VIH y al Sida en un grupo de adolescentes y jóvenes universitarios colombianos. Para ello, se realizó un estudio cualitativo de diseño fenomenológico interpretativo en el que participaron 18 estudiantes universitarios. Las técnicas de recolección empleadas fueron las redes semánticas naturales (RSN) y los grupos de discusión. Las narrativas evidenciaron que existe desconocimiento sobre aspectos generales del VIH y del Sida. También dieron cuenta de la creencia de que el riesgo de contraer VIH recae únicamente en grupos etiquetados en riesgo. Se identificaron, además, actitudes que denotan estigma hacia personas con la enfermedad. Los pares, los padres, la familia y el internet se reportaron como los principales agentes de socialización sobre la enfermedad. En conclusión, se destaca la necesidad de empoderar a los diferentes agentes de socialización y de fortalecer los procesos educativos desde el reconocimiento de los derechos humanos de todas las personas. Se requiere, por tanto, un trabajo articulado, integral y transversal de los diferentes agentes, no solo para la deconstrucción de las creencias y actitudes negativas hacia la enfermedad, sino para la construcción de una sexualidad responsable y saludable que esté centrada en el autocuidado.
O ensino das ciências sociais e humanas na graduação em saúde coletiva: entre desafios e oportunidades de transgressões

Published: July 2019

Resumo A implantação, em 2009, do curso de graduação em saúde coletiva (GSC) no Brasil e sua progressiva disseminação trouxe à tona velhas questões de ordem epistemológica, prática ou político-institucional relacionadas ao ensino das ciências sociais e humanas (CSH) nesse contexto e fez emergir outras. Sobretudo, esse novo curso recoloca no centro do debate a questão da identidade do campo da saúde coletiva ou as especificidades de seus objetos, atores/agentes, conhecimentos e práticas. Afinal, tanto os projetos pedagógicos (perfil de egresso, estrutura curricular etc.) quanto seu modus operandi refletem uma dada concepção do campo. Propõe-se, neste artigo, discutir peculiaridades e desafios do ensino das CSH na GSC, considerando esses elementos a partir da análise da experiência de um curso em particular ou, melhor dito, do compartilhamento de vivências e impressões das autoras que integram seu corpo docente. Na primeira parte do texto, são esboçados argumentos em defesa da formação emancipatória e do conhecimento pluriuniversitário, apoiados no diálogo com Boaventura de Souza Santos. Entende-se que tais perspectivas são especialmente bem-vindas na GSC, a qual tem se revelado um espaço profícuo de experimentação de novas formas de agir na educação e na saúde.
Nucleação na formação de estruvita: estado da arte

RESUMO Estimativas recentes indicam que a duração de toda a reserva de rochas fosfatadas do planeta não ultrapassa 400 anos e que a produção de fertilizantes nitrogenados é insustentável energeticamente. Atualmente, o tratamento de esgoto está sendo visto como uma unidade de recuperação de recursos (água, energia e nutrientes) em vez de uma de final de tubo. Portanto, as tecnologias de recuperação devem ser priorizadas em relação às de remoção. Estruvita (fosfato de amônio e magnésio) é um cristal que pode ser produzido a partir do esgoto doméstico e tem maior eficiência agrícola do que os fertilizantes convencionais. Apesar de a cristalização ser um tema bastante estudado em todo o mundo e extremamente desenvolvido tecnologicamente, sua utilização na engenharia sanitária ainda não é comum, especialmente no Brasil. Um dos assuntos menos pesquisados na formação da estruvita é a nucleação. Portanto, o presente artigo traz uma revisão bibliográfica crítica e atual e mostra as lacunas no conhecimento sobre esse assunto.
Soil, basin and soil–building–soil interaction effects on motions of Mexico City during seven earthquakes
Authors: Garini Evangelia , Anastasopoulos Ioannis , Gazetas George
Published: July 2019

Starting with the destructive 1985 Michoacan Mw8·0 earthquake, the lake zone of Mexico City has been experiencing ground motions bearing the effects of strong soil amplification at specific site-dependent periods. Last year's Mw = 7·1 Puebla earthquake, although less damaging, with different orientation and mechanism, and at a much shorter distance than the 1985 event, nevertheless produced records bearing similar soil amplification effects and even rather similar motions on rock. This paper concentrates on four sites, distinguished mainly by the thickness of the soft clay, on which three to seven seismic events (with Mw > 6·5) have been recorded. Using the corresponding records on two hilly zone sites as base rock motions, amplification functions in terms of ratios of top-over-base recorded acceleration response spectra are studied. Although the dominant periods of each amplification function confirm the occurrence of resonance at the fundamental natural period of each particular soil stratum, differences between the amplification functions of the east–west and north–south components are evident. Using the actual soil profile of two of these stations, along with the G:γ and ξ:γ curves from the general literature and from site-specific measurements, one-dimensional wave propagation analyses are conducted. Reasonable agreement with the records is generally found in terms of response spectra. However, weak motions recorded in some events (where soil behaved essentially linearly) exhibit a number of beating cycles which last for almost one additional minute beyond 60 s, and which are barely noticeable in the computed motions. An oversimplified (in geometry and properties) two-dimensional basin, 6 km long, containing 60 m of Mexico City clay, is analysed with finite elements, excited by the rock outcrop hilly zone records. Wave propagation in this basin reveals the generation of Rayleigh waves at the edge, which move towards the centre and interfere with the incident and reflected S and P waves. The resulting motions away from the edge resemble the recorded motions at the CAO site in a 1999 earthquake better than the one-dimensional analysis, but are still far from satisfactorily reproducing the beating. An additional factor to qualitatively explain reality is generically examined: the oscillations of a tall (15-storey) building and the feedback of its free oscillations into the ground (soil–building–soil interaction) are found to increase free-field accelerations slightly.
Tempo e caos: a “imaginação dos possíveis” e os média
Authors: Castro Gustavo , Dravet Florence
Published: July 2019

Este artigo propõe uma reflexão sobre a noção de tempo e suas relações com os média, a partir dos estudos da complexidade e numa perspetiva transdisciplinar. Iniciando com reflexões sobre narrativas literárias e cinematográficas, o nosso objetivo é perceber como a noção de tempo é mediadora da compreensão da realidade espaço/tempo e da perceção estética do mundo entre ordem e caos. Recorremos ao diálogo entre ciência e narrativa e ao pensamento da física moderna sobre os conceitos de tempo, ordem e caos. As nossas conclusões apontam para três ideias: 1) a constante rememoração da catástrofe é um tema íntimo obsessivo que se apresenta através da narrativa artística e mediática; 2) a expressão da obsessão catastrófica vem suprir parcialmente o afeto pelo horror da humanidade atual e 3) o imaginário da catástrofe atravessa tempo e espaço e é transdisciplinar.
Comedy’s time spell
Authors: Jerónimo Nuno Amaral , Alexandre José Carlos
Published: July 2019

In this paper, the authors intend to reflect upon the social time interrupted by humor, as a discourse recipe, and by comedy, as a performative resource. The incongruity of the significations produced by this stylistic form means a suspension of the tipification rules in the life-world daily interactions. These moments of suspension are designated by time out. In this text, the authors show how humour and comedy connect with common time and time out to reveal interpretation keys to disclose the intersubjective social fabric.
Space-time compression and hyperlocalisation: the new flâneurs
Authors: Santos Ivone Neiva , Azevedo José
Published: July 2019

The experience of sensations such as time acceleration and space elimination has become common in modern life, which is increasingly organised in tune with the “real time” imposed by digital media. Throughout this article and starting with the concept of “time compression” presented by David Harvey (1999), the authors contrast technological determinism with other perspectives that suggest there is a dialogue-based relationship between technology and society. The text discusses notions such as deterritorialisation and detemporalisation that make it possible to understand the emergence of a fragmented and timeless data space, which corresponds to a “new geography”, in which it is no longer possible to establish a clear boundary between the physical and the digital world. The text is theoretically underpinned by the concept of the cyberflâneur, exploring the similarities with the 19th century flâneur described by Baudelaire (1996). Analysis of a set of artistic and experimental interventions addressing issues such as hyperlocalisation or ubiquity and pervasiveness enables us to use the character of the cyberflâneur in a twofold sense – as a sign of technical acceleration and also as a symbol of resistance to such acceleration. The authors conclude that the exponential evolution and increasing “naturalisation” of technology obligates us to consider its determining role in social dynamics, namely by transforming our relationship with the dimensions of space and time.
