Dentro, fora, antes ou depois? – A política espaço-temporal de Notícias da América, de Paulo Nazareth

This article investigates the performance Notícias da América, by the artist Paulo Nazareth. It identifies discussions (and actions) that handle a plurality of pasts (ancestral, colonial) and, at the same time, open relational perspectives a-typical feature of contemporary art since the 1960s. In that performance, as Nazareth moves through Latin American cities, the images and discourses produced forge a common space between himself, his interlocutors and the landscape. Simultaneously, a multiple temporality emerges in which peripheral subjectivities become visible. It is also from this space-time relationship that other of his artistic productions (such as the series Aqui é arte) can be unfolded.Este artigo investiga a performance Notícias da América, do artista Paulo Nazareth. Nela são identificadas discussões (e ações) que manejam uma pluralidade de passados (ancestrais, coloniais) e, ao mesmo tempo, abrem perspectivas relacionais, característica típica da arte contemporânea desde os anos 1960. Na performance, à medida que Nazareth se desloca por cidades latino-americanas, as imagens e os discursos produzidos forjam um espaço comum entre ele próprio, seus interlocutores e a paisagem. Simultaneamente, emerge uma temporalidade múltipla em que subjetividades periféricas se tornam visíveis. É também a partir dessa relação espaço-temporal que outras de suas produções artísticas (como a série Aqui é arte), podem ser desdobradas

Quality of High-protein Diet Bar Plus Chia (Salvia hispanica L.) Grain Evaluated Sensorially by Untrained Tasters

The objective of this study was to develop, analyze composition and evaluate the microbiological and sensory characteristics of high-protein diet bars (PB) with the addition of chia grain (Salvia hispanica L.), partially replacing isolated soy protein and concentrated whey protein, in proportions of 0, 10, 15 and 20%. The proximate composition was analyzed of PB, for microbiological quality of Bacillus cereus, Filamentous fungi and yeast count, total fecal coliforms, and Salmonella ssp. search. Sensory analysis was performed utilizing acceptance testing of characteristics on a nine-point hedonic scale for various attributes, including purchasing intention of the tested PB. Bars showed 20% moisture, 2.3% ash, 20-23% protein and 19% lipids. The effect of increasing of chia was to increase crude fiber content and decrease total carbohydrate and total energy value. All samples were within the microbiological food standards established by current legislation. All PB formulations obtained a good overall impression index and all characteristics were above mean grades, with the exception of taste (63%) in the PB containing 0% chia. Chia grain has a positive influence on sensory aspects and appears to be an alternative way to increase the nutritional quality of high-protein diet bars

Bilateral Anophthalmia in Feline

Background: Anophthalmia is a rare, congenital condition, defined as the complete absence of the eye bulb due to inadequate growth of the vesicle or optic dome. The malformation can be primary (in the absence of complete), secondary (in the presence of only residual tissue), or degenerative (in which the eye begins to form, but for some reason, it begins to degenerate). This condition is rare in dogs, cats, cattle, and sheep. Microscopic evaluation of orbital tissue for identification is always recommended. The aim of this study was to report a case of bilateral anophthalmia in a domestic cat.Case: A feline male, healthy, Maine Coon breed with 60 days of life was attended at the one veterinary private clinic. The cat, negative for FIV and FeLV, was born in a commercial cattery, belonging to his mother's third litter, healthy litter with the exception of this feline. He arrived with a complaint of not opening his eyelids, like the rest of the litter. In the clinical examination, it was found the normality of vital signs, absence of other visible anatomical abnormalities, only the ocular region was observed with closed eyelids. The initial suspicions were anophthalmia and microphthalmia. The patient was referred for an ocular ultrasound, which showed the complete absence of the right and left eye bulbs. The right and left orbital cavities had only a volume of soft, amorphous, and predominantly homogeneous tissue. After the ultrasound report, the patient underwent a surgical procedure to remove a fragment of tissue from the eye socket, which was sent for histopathological examination to confirm anophthalmia and discard the differential diagnosis of microphthalmia. Microscopy revealed immature, epithelial, and glandular tissue in the middle of discrete and moderate connective tissue, loosely arranged. In some fragments, cartilaginous tissue was also revealed. Thus, the histological findings are compatible with immature, pseudoformed tissues and without neoplastic characteristics. The diagnosis of secondary anophthalmia was reached with use of ultrasound and histological reports.Discussion: Congenital malformations in domestic cats are less frequent than in dogs, some of which are rare, and little reported. Secondary anophthalmia in the reported patient was confirmed by histological and ultrasound examination. Bilateral secondary anophthalmia is characterized by the absence of the eyeball, but with the presence of adjacent tissue. The animal was submitted to an ocular ultrasound examination and the complete absence of ocular bulbs was found. The differential diagnosis of microphthalmia was ruled out because there was no evidence of the eyeball. Microphthalmia is a common congenital ophthalmic disorder in veterinary medicine. Representative fragments were submitted to histopathological examination, where immature, epithelial tissue was found. In some fragments sent for analysis, cartilaginous tissue was observed. The histological findings are compatible with immature, pseudoformed tissues, thus verifying bilateral congenital anophthalmia in the reported animal. The clinical examination in these cases serves to ensure that the animal does not have any other congenital changes, allowing a favorable prognosis in puppies. Based on the information presented, the animal in this study has bilateral secondary congenital anophthalmia, with a favorable prognosis for the patient to live with certain normality, with quality and well-being

High-Protein bar Supplemented with Chia Seed Improves Lipidemic Parameters in Wistar Rats

Chia (Salvia hispanical.) seeds are known to have high content of polyunsaturated fatty acids (PUFA) and fiber. This study aimed to evaluate the effect of a High-Protein Bar (PB) supplemented with chia seed added to the feed on the organs, tissues, and biochemical parameters of male Wistar adult rats (n=32) divided into four groups (n=8), namely group I (ration + 20% chia seeds); group II (ration + PB without chia seeds); group III (ration + 20% PB containing 15% chia seed); group IV (ration + 20% PB containing 20% chia seeds). The shelf-life of PBs was assessed during 45 days in terms of texture, color, and antioxidant activity using the \u3b2-carotene/linoleic acid assay. The centesimal composition of the formulations showed a significantly higher value of fiber offered to group I. Animals of groups III and IV showed a lower consumption of the ration (p<0.05), while those of group I lower weight of the heart as well as of retroperitoneal, epididymal and perirenal tissues (p<0.05). The biochemical parameters showed a significant improvement (p<0.05) in testosterone levels in groups that received the rations partially replaced by chia seed-containing PB. In addition, group II, which received the ration enriched with PB without chia seed, showed the highest serum triacylglycerol value, highlighting the important role of chia seeds on lipidemic parameters. It is worth mentioning that more in-depth studies must be carried out to validate the results obtained in the current study

A epidemiologia do câncer de mama em Roraima / The epidemiology of breast cancer in Roraima

O câncer de mama é um grande problema de saúde pública, sendo o diagnóstico na sua fase inicial de suma importância para um melhor prognóstico e tratamento da mulher afetada. O presente estudo traz como objetivos traçar um perfil epidemiológico do câncer de mama, no Estado de Roraima entre os anos de 2009 a 2013, bem como verificar se a mamografia influencia na melhoria das taxas de letalidade. Procurou-se, também, comparar a incidência da neoplasia mamária nas regiões do Brasil e entre indivíduos indígenas e não indígenas de Roraima. Para isso, o estudo foi realizado quantitativamente com dados obtidos através da plataforma SISMAMA, INCA e IBGE e complementado com a análise qualitativa de tais informações e de seus efeitos na epidemiologia do Estado. O estudo aponta possível deficiência no sistema preventivo, o que acarreta uma suscetibilidade maior a prognósticos ruins. Ressalta-se, então, a importância da melhoria da rede de atendimento, para a realização de mamografias preventivas, a fim aumentar a probabilidade de tratamento efetivo, cura e estudos mais aprofundados que evidenciem a problemática.

Root microbiota drive direct integration of phosphate stress and immunity

Plants live in biogeochemically diverse soils that harbor extraordinarily diverse microbiota. Plant organs associate intimately with a subset of these microbes; this community’s structure can be altered by soil nutrient content. Plant-associated microbes can compete with the plant and with each other for nutrients; they can also provide traits that increase plant productivity. It is unknown how the plant immune system coordinates microbial recognition with nutritional cues during microbiome assembly. We establish that a genetic network controlling phosphate stress response influences root microbiome community structure, even under non-stress phosphate conditions. We define a molecular mechanism regulating coordination between nutrition and defense in the presence of a synthetic bacterial community. We demonstrate that the master transcriptional regulators of phosphate stress response in Arabidopsis also directly repress defense, consistent with plant prioritization of nutritional stress over defense. Our work will impact efforts to define and deploy useful microbes to enhance plant performance

Atlantic circulation and ice sheet influences on upper South Atlantic temperatures during the last deglaciation. Paleoceanography and Paleoclimatology, 34(6), (2019): 990-1005, doi:10.1029/2019PA003558.Atlantic Meridional Overturning Circulation (AMOC) disruption during the last deglaciation is hypothesized to have caused large subsurface ocean temperature anomalies, but records from key regions are not available to test this hypothesis, and other possible drivers of warming have not been fully considered. Here, we present the first reliable evidence for subsurface warming in the South Atlantic during Heinrich Stadial 1, confirming the link between large‐scale heat redistribution and AMOC. Warming extends across the Bølling‐Allerød despite predicted cooling at this time, thus spanning intervals of both weak and strong AMOC indicating another forcing mechanism that may have been previously overlooked. Transient model simulations and quasi‐conservative water mass tracers suggest that reduced northward upper ocean heat transport was responsible for the early deglacial (Heinrich Stadial 1) accumulation of heat at our shallower (~1,100 m) site. In contrast, the results suggest that warming at our deeper site (~1,900 m) site was dominated by southward advection of North Atlantic middepth heat anomalies. During the Bølling‐Allerød, the demise of ice sheets resulted in oceanographic changes in the North Atlantic that reduced convective heat loss to the atmosphere, causing subsurface warming that overwhelmed the cooling expected from an AMOC reinvigoration. The data and simulations suggest that rising atmospheric CO2 did not contribute significantly to deglacial subsurface warming at our sites.We thank H. Abrams, G. Swarr, and J.

Effects of Resistance Training on Oxidative Stress Markers and Muscle Damage in Spinal Cord Injured Rats

Background: Spinal cord injury (SCI) is a condition that affects the central nervous system, is characterized by motor and sensory impairments, and impacts individuals’ lives. The objective of this study was to evaluate the effects of resistance training on oxidative stress and muscle damage in spinal cord injured rats. Methodology: Forty Wistar rats were selected and divided equally into five groups: Healthy Control (CON), Sham (SHAM) SCI Untrained group (SCI-U), SCI Trained group (SCI- T), SCI Active Trained group (SCI- AT). Animals in the trained groups were submitted to an incomplete SCI at T9. Thereafter, they performed a protocol of resistance training for four weeks. Results: Significant differences in muscle damage markers and oxidative stress in the trained groups, mainly in SCI- AT, were found. On the other hand, SCI- U group presented higher levels of oxidative stress and biomarkers of LDH and AST. Conclusion: The results highlight that resistance training promoted a decrease in oxidative stress and a significative response in muscle damage markers. Keywords: spinal cord injury; resistance training; oxidative stress; muscle damag
