description: 4-Hydroxyphenylacetate decarboxylase (4Hpad) is the prototype of a new class of Fe-S cluster-dependent glycyl radical enzymes (Fe-S GREs) acting on aromatic compounds. The two-enzyme component system comprises a decarboxylase responsible for substrate conversion and a dedicated activating enzyme (4Hpad-AE). The decarboxylase uses a glycyl/thiyl radical dyad to convert 4-hydroxyphenylacetate into p-cresol (4-methylphenol) by a biologically unprecedented Kolbe-type decarboxylation. In addition to the radical dyad prosthetic group, the decarboxylase unit contains two [4Fe-4S] clusters coordinated by an extra small subunit of unknown function. 4Hpad-AE reductively cleaves S-adenosylmethionine (SAM or AdoMet) at a site-differentiated [4Fe-4S]2+/+ cluster (RS cluster) generating a transient 5′-deoxyadenosyl radical that produces a stable glycyl radical in the decarboxylase by the abstraction of a hydrogen atom. 4Hpad-AE binds up to two auxiliary [4Fe-4S] clusters coordinated by a ferredoxin-like insert that is C-terminal to the RS cluster-binding motif. The ferredoxin-like domain with its two auxiliary clusters is not vital for SAM-dependent glycyl radical formation in the decarboxylase, but facilitates a longer lifetime for the radical. This review describes the 4Hpad and cognate AE families and focuses on the recent advances and open questions concerning the structure, function and mechanism of this novel Fe-S-dependent class of GREs.

description: Event cameras are bio-inspired sensors that offer advantages over traditional cameras. They operate asynchronously, sampling the scene at microsecond resolution and producing a stream of brightness changes. This unconventional output has sparked novel computer vision methods to unlock the camera's potential. Here, the problem of event-based stereo 3D reconstruction for SLAM is considered. Most event-based stereo methods attempt to exploit the high temporal resolution of the camera and the simultaneity of events across cameras to establish matches and estimate depth. By contrast, this work investigates how to estimate depth without explicit data association by fusing Disparity Space Images (DSIs) originated in efficient monocular methods. Fusion theory is developed and applied to design multi-camera 3D reconstruction algorithms that produce state-of-the-art results, as confirmed by comparisons with four baseline methods and tests on a variety of available datasets.

description: The kinetics of the charge carrier recombination in dye molecule-doped multilayer organic light-emitting diodes (OLEDs) was quantified by transient electroluminescence (EL). Three sets of dye molecules, such as derivatives of naphthalimide and stilbene, were used as dopants in light-emission layer. Although the devices show almost the same EL spectra for each set of molecules, they show very different EL efficiency. The difference in EL efficiency was attributed to the difference in charge carrier recombination, as revealed by transient EL. The recombination coefficient (γ) was determined from the long-time component of the temporal decay of the EL intensity after a rectangular voltage pulse was turned off. It was found that γ and EL efficiency were both strongly dependent on the molecular structures of the dopants, and the donor groups and π-conjugated structure guaranteed high γ and EL efficiency in OLEDs.

Subjects: subject: Depression

subject: 610 Medizin und Gesundheit

description: Depression is among the major long-term complications of cerebral stroke. Occurring in about 30% of all stroke survivors, ‘poststroke depression' (PSD) is known to be associated with prolonged recovery, reduced quality of life, and increased mortality. Research over the past 25 years has enlarged our knowledge about organic and psychosocial risk factors, but their interaction is still unclear. In this paper, we start by reviewing and discussing pathogenetic PSD models that were proposed in the 1980s and 1990s. Based on these earlier approaches and on longitudinal research published since that time, a biphasic model is proposed that reflects the current knowledge on the emergence of PSD. The model integrates premorbid, stroke-related and psychosocial risk factors contributing to the emergence of PSD within the first 2 years after stroke. The distinction between ‘reactive' and ‘organic' PSD has been dropped, and groups of well-documented predictors are recommended for future research. Finally, we will outline possible implications of the model for prevention and therapy.

description: In the first billion years after its formation, the Galaxy underwent several mergers with dwarf satellites of various masses. The debris of Gaia-Sausage/Enceladus (GSE), the galaxy responsible for the last significant merger of the Milky Way, dominates the inner halo and has been suggested to be the progenitor of both the Hercules-Aquila Cloud (HAC) and Virgo Overdensity (VOD). We combine SEGUE, APOGEE, Gaia, and StarHorse distances to characterize the chemodynamical properties and verify the link between HAC, VOD, and GSE. We find that the orbital eccentricity distributions of the stellar overdensities and GSE are comparable. We also find that they have similar, strongly peaked, metallicity distribution functions, reinforcing the hypothesis of common origin. Furthermore, we show that HAC and VOD are indistinguishable from the prototypical GSE population within all chemical-abundance spaces analyzed. All these evidences combined provide a clear demonstration that the GSE merger is the main progenitor of the stellar populations found within these halo overdensities.

Year: 2013

description: Introdução: A análise histopatológica de tecido ósseo exige uma etapa de descalcificação. O método usual consiste na imersão das amostras em ácidos, mas para além de provocarem danos tecidulares, o processo é prolongado. A utilização de micro-ondas acelera a descalcificação, mas não deve comprometer a imagem microscópica. Objetivo: Diminuir a duração da descalcificação, mantendo a qualidade da imagem microscópica. Metodologia: Foram testadas amostras de osso compacto e esponjoso. Realizou-se a descalcificação pelo método convencional e pelo método em micro-ondas, através da adaptação de um protocolo conhecido. Utilizou-se ácido nítrico a 5% e 10%. Resultados: Nos fragmentos de maiores dimensões, após 4 horas com ácido nítrico a 10% em micro-ondas, não se conseguiu uma descalcificação completa, apesar da imagem histológica ser razoável. Nos fragmentos de osso esponjoso, verificou-se uma redução de cerca de 25 horas relativamente ao método convencional. Nas biópsias, houve uma redução de aproximadamente 10 horas, utilizando ácido nítrico a 5%. Com ácido nítrico a 10% houve destruição tecidular. Nos casos em que se obteve uma descalcificação completa, a imagem microscópica apresenta fraca qualidade. Conclusão: A utilização de micro-ondas com ácido nítrico a 5%/10%, aplicando o protocolo deste estudo, reduz a duração da descalcificação, mas compromete a imagem microscópica.

description: Real-world image denoising is a practical image restoration problem that aims to obtain clean images from in-the-wild noisy inputs. Recently, the Vision Transformer (ViT) has exhibited a strong ability to capture long-range dependencies, and many researchers have attempted to apply the ViT to image denoising tasks. However, a real-world image is an isolated frame that makes the ViT build long-range dependencies based on the internal patches, which divides images into patches, disarranges noise patterns and damages gradient continuity. In this article, we propose to resolve this issue by using a continuous Wavelet Sliding-Transformer that builds frequency correspondences under real-world scenes, called DnSwin. Specifically, we first extract the bottom features from noisy input images by using a convolutional neural network (CNN) encoder. The key to DnSwin is to extract high-frequency and low-frequency information from the observed features and build frequency dependencies. To this end, we propose a Wavelet Sliding-Window Transformer (WSWT) that utilizes the discrete wavelet transform (DWT), self-attention and the inverse DWT (IDWT) to extract deep features. Finally, we reconstruct the deep features into denoised images using a CNN decoder. Both quantitative and qualitative evaluations conducted on real-world denoising benchmarks demonstrate that the proposed DnSwin performs favorably against the state-of-the-art methods.

We show that the resulting infinitely many contact 5-manifolds are all diffeomorphic but pairwise non-contactomorphic. Moreover, we explicitly determine these contact 5-manifolds.

description: As tetraciclinas são compostos antibacterianos utilizados em bovinos de leite para tratamento de doenças infecciosas, como a mastite, mas também como aditivos em ração animal. O uso das tetraciclinas pode conduzir à presença de resíduos destes fármacos no leite, principalmente se não forem utilizados de acordo com as indicações, nem respeitado o período mínimo de eliminação dos antibióticos pelo leite. A presença de resíduos de antibióticos no leite interfere no processo industrial dos seus derivados, podendo inviabilizar a produção destes e, consequentemente, causar igualmente prejuízos económicos, como por exemplo, pela inibição de fermentos lácticos que são culturas de microorganismos utilizados na produção de iogurtes, queijos e outros produtos lácteos. Os resíduos de antibióticos no leite de consumo podem representar riscos à saúde humana, podendo causar reacções alérgicas em indivíduos sensíveis ou ter um efeito adverso na flora intestinal humana, prejudicando a sua acção protectora local, além de propiciar a selecção de populações bacterianas resistentes.

description: Multimodal sentiment analysis and depression estimation are two important research topics that aim to predict human mental states using multimodal data. Previous research has focused on developing effective fusion strategies for exchanging and integrating mind-related information from different modalities. Some MLP-based techniques have recently achieved considerable success in a variety of computer vision tasks. Inspired by this, we explore multimodal approaches with a feature-mixing perspective in this study. To this end, we introduce CubeMLP, a multimodal feature processing framework based entirely on MLP. CubeMLP consists of three independent MLP units, each of which has two affine transformations. CubeMLP accepts all relevant modality features as input and mixes them across three axes. After extracting the characteristics using CubeMLP, the mixed multimodal features are flattened for task predictions. Our experiments are conducted on sentiment analysis datasets: CMU-MOSI and CMU-MOSEI, and depression estimation dataset: AVEC2019. The results show that CubeMLP can achieve state-of-the-art performance with a much lower computing cost.

description: We investigate features of the lateral distribution function (LDF) of the radio signal emitted by cosmic ray air-showers with primary energies $> 0.1$~EeV and its connection to air-shower parameters such as energy and shower maximum using CoREAS simulations made for the configuration of the Tunka-Rex antenna array. Taking into account all significant contributions to the total radio emission, such as by the geomagnetic effect, the charge excess, and the atmospheric refraction we parameterize the radio LDF. This parameterization is two-dimensional and has several free parameters. The large number of free parameters is not suitable for experiments of sparse arrays operating at low SNR (signal-to-noise ratios). Thus, exploiting symmetries, we decrease the number of free parameters and reduce the LDF to a simple one-dimensional function. The remaining parameters can be fit with a small number of points, i.e. as few as the signal from three antennas above detection threshold. Finally, we present a method for the reconstruction of air-shower parameters, in particular, energy and $X_{\mathrm{max}}$ (shower maximum), which can be reached with a theoretical accuracy of better than 15\% and 30~g/cm$^2$, respectively.

description: The Salford Samples is a practice-as-research project in intermedial place-making. Using materials that arise from the city of Salford, including fragments of its cultural history, an autobiographical audio diary, and images/footage of the place itself, a range of shifting combinations are created. Through the mixing of diverse materials, as part of live performances and in online 'video-texts', issues related to this fast-moving, redeveloping, and conversely traditional and static place, arise. Specifically, questions around 'solastalgia' or 'the distress that is produced by environmental change impacting on people while they are directly connected to their home environment’ (Albrecht et al. 2007, 95) emerge. In addition, these factors both foster and disrupt 'place-attachment' in a contemporary urban environment.

description: Orbital eccentricity is a key signature of dynamical binary black hole formation. The gravitational waves from a coalescing binary contain information about its orbital eccentricity, which may be measured if the binary retains sufficient eccentricity near merger. Dedicated waveforms are required to measure eccentricity. Several models have been put forward, and show good agreement with numerical relativity at the level of a few percent or better. However, there are multiple ways to define eccentricity for inspiralling systems, and different models internally use different definitions of eccentricity, making it difficult to directly compare eccentricity measurements. In this work, we systematically compare two eccentric waveform models, $\texttt{SEOBNRE}$ and $\texttt{TEOBResumS}$, by developing a framework to translate between different definitions of eccentricity. This mapping is constructed by minimizing the relative mismatch between the two models over eccentricity and reference frequency, before evolving the eccentricity of one model to the same reference frequency as the other model. We show that for a given value of eccentricity passed to $\texttt{SEOBNRE}$, one must input a $20$-$50\%$ smaller value of eccentricity to $\texttt{TEOBResumS}$ in order to obtain a waveform with the same empirical eccentricity. We verify this mapping by repeating our analysis for eccentric numerical relativity simulations, demonstrating that $\texttt{TEOBResumS}$ reports a correspondingly smaller value of eccentricity than $\texttt{SEOBNRE}$.

As an intermediate result, we obtain that non-Cohen-Macaulay factorial rings cannot contain Cohen-Macaulay ideals. For modular cyclic groups of prime order, we show that the quotient of the invariant ring modulo the transfer ideal is always Cohen-Macaulay, extending a result of Fleischmann.

description: We consider the rotation of neutrally buoyant axisymmetric particles suspended in isotropic turbulence. Using laboratory experiments as well as numerical and analytical calculations, we explore how particle rotation depends upon particle shape. We find that shape strongly affects orientational trajectories, but that it has negligible effect on the variance of the particle angular velocity. Previous work has shown that shape significantly affects the variance of the tumbling rate of axisymmetric particles. It follows that shape affects the spinning rate in a way that is, on average, complementary to the shape-dependence of the tumbling rate. We confirm this relationship using direct numerical simulations, showing how tumbling rate and spinning rate variances show complementary trends for rod-shaped and disk-shaped particles. We also consider a random but non-turbulent flow. This allows us to explore which of the features observed for rotation in turbulent flow are due to the effects of particle alignment in vortex tubes.

description: Background: A wider subjective time horizon is assumed to be positively associated with longevity and vitality. In particular, a lifestyle with exposure to novel and varied information is considered beneficial for healthy cognitive aging. At present, measures that specifically assess individuals' perceived temporal extension to engage in active lifestyles in the future are not available. Objectives: We introduce and validate a new self-report measure, the Subjective Health Horizon Questionnaire (SHH-Q). The SHH-Q assesses individuals' future time perspectives in relation to four interrelated but distinct lifestyle dimensions: (1) novelty-oriented exploration (Novelty), (2) bodily fitness (Body), (3) work goals (Work), and (4) goals in life (Life Goals). The present study aims at: (a) validating the hypothesized factor structure of the SHH-Q, according to which the SHH-Q consists of four interrelated but distinct subscales, and (b) testing the hypothesis that the Novelty and Body subscales of the SHH-Q show positive and selective associations with markers of cognition and somatic health, respectively. Methods: Using structural equation modeling, we analyzed data from 1,371 healthy individuals (51% women) with a mean age of 70.1 years (SD = 3.6) who participated in the Berlin Aging Study II (BASE-II) and completed the SHH-Q. Results: As predicted, the SHH-Q formed four correlated but distinct subscales: (1) Novelty, (2) Body, (3) Work, and (4) Life Goals. Greater self-reported future novelty orientation was associated with higher current memory performance, and greater future expectations regarding bodily fitness with better current metabolic status. Conclusion: The SHH-Q reliably assesses individual differences in four distinct dimensions of future time perspective. Two of these dimensions, Novelty and Body, show differential associations with cognitive status and somatic health. The SHH-Q may serve as a tool to assess how different facets of future time perspective relate to somatic health, cognition, motivation, and affect, and may help to identify the socioeconomic and individual antecedents, correlates, and consequences of an active lifestyle.

description: High-energetic gamma rays from astrophysical targets constitute a unique probe for annihilation or decay of heavy particle dark matter (DM). After several decades, diverse null detections have resulted in strong constraints for DM particle masses up to the TeV scale. While the gamma-ray signature is expected to be universal from various targets, uncertainties of astrophysical origin strongly affect and weaken the limits. At the same time, spurious signals may originate from non-DM related processes. The many gamma-ray targets in the extragalactic sky being searched for DM play a crucial role to keep these uncertainties under control and to ultimately achieve an unambiguous DM detection. Lately, a large progress has been made in combined analyses of TeV DM candidates towards different targets by using data from various instruments and over a wide range of gamma-ray energies. These approaches not only resulted in an optimal exploitation of existing data and an improved sensitivity, but also helped to level out target- and instrument-related uncertainties. This review gathers all searches in the extragalactic sky performed so far with the space-borne Fermi-Large Area Telescope, the ground-based imaging atmospheric Cherenkov telescopes, and the High-Altitude Water Cherenkov Gamma-Ray Observatory (HAWC). We discuss the different target classes and provide a complete list of all analyses so far.

description: As infeções do trato urinário (ITU’s) são doenças infeciosas frequentes na prática clínica veterinária, sendo fundamental uma correta antibioterapia, principalmente pelo crescente desenvolvimento de resistências bacterianas aos antibióticos. Realizou-se um estudo retrospetivo, englobando 86 animais admitidos no Hospital Veterinário do Restelo, submetidos a urocultura, com o objetivo de caracterizar as ITU’s microbianas neste hospital, avaliando a sua epidemiologia e suscetibilidade antibiótica das bactérias isoladas. Da totalidade das uroculturas realizadas (n=86), 28 foram positivas, 18 em canídeos e 10 em felídeos, sem predisposição racial, mais em fêmeas nos canídeos e em machos nos felídeos. A idade média dos animais com ITU foi 8 anos nos canídeos e 10 anos nos felídeos. Todas as ITU´s foram monobacterianas, sendo o microorganismo mais frequentemente isolado a Escherichia coli. Verificou-se multirresistência em 10 das 28 bactérias isoladas. A gentamicina foi o antibiótico com melhor perfil de sensibilidade global e o que apresentou mais resistências foi a tetraciclina. O antibiótico mais prescrito de forma empírica foi a enrofloxacina. Este estudo, especialmente se realizado de forma periódica, poderá ser um contributo para a elaboração de guias institucionais de antibioterapia adequada e minimização do aparecimento de resistências bacterianas.

description: This article describes a case report of a feline cutaneous lymphangioma. Lymphangiomas (synonym: lymphangiomatosis) and lymphangiosarcomas are rare tumors, usually associated with skin, some are believed to be congenital in young animals associated with vascular abnormalities. In gross pathology description they are poorly defined, cavernous-spongy, soft and they may be identified along fascial planes, because of this it may be difficult to remove, so tumors tend to recur. In histopathology description we can see interconnecting channels lined by endothelium usually without erythrocytes, but these tumors do not have unique features.

description: There is evidence that biological systems, such as the brain, work at a critical regime robust to noise, and are therefore able to remain in it under perturbations. In this work, we address the question of robustness of critical systems to noise. In particular, we investigate the robustness of stochastic cellular automata (CAs) at criticality. A stochastic CA is one of the simplest stochastic models showing criticality. The transition state of stochastic CA is defined through a set of probabilities. We systematically perturb the probabilities of an optimal stochastic CA known to produce critical behavior, and we report that such a CA is able to remain in a critical regime up to a certain degree of noise. We present the results using error metrics of the resulting power-law fitting, such as Kolmogorov-Smirnov statistic and Kullback-Leibler divergence. We discuss the implication of our results in regards to future realization of brain-inspired artificial intelligence systems.

EQUINE CONCEPTUS DEVELOPMENT – A MINI REVIEW

description: Many aspects of early embryonic development in the horse are unusual or unique; this is of scientific interest and, in some cases, considerable practical significance. During early development the number of different cell types increases rapidly and the organization of these increasingly differentiated cells becomes increasingly intricate as a result of various inter-related processes that occur step-wise or simultaneously in different parts of the conceptus (i.e., the embryo proper and its associated membranes and fluid). Equine conceptus development is of practical interest for many reasons. Most significantly, following a high rate of successful fertilization (71-96%) (Ball, 1988), as many as 30-40% of developing embryos fail to survive beyond the first two weeks of gestation (Ball, 1988), the time at which gastrulation begins. Indeed, despite considerable progress in the development of treatments for common causes of sub-fertility and of assisted reproductive techniques to enhance reproductive efficiency, the need to monitor and rebreed mares that lose a pregnancy or the failure to produce a foal, remain sources of considerable economic loss to the equine breeding industry. Of course, the potential causes of early embryonic death are numerous and varied (e.g. persistent mating induced endometritis, endometrial gland insufficiency, cervical incompetence, corpus luteum (CL) failure, chromosomal, genetic and other unknown factors (LeBlanc, 2004). However, the problem is especially acute in aged mares with a history of poor fertility in which the incidence of embryonic loss between days 2 and 14 after ovulation has been reported to reach 62-73%, and in which embryonic death is due primarily to embryonic defects rather than to uterine pathology (Ball et al., 1989; Carnevale & Ginther, 1995; Ball, 2000).

description: We present a self-consistent cross-calibration of the three main molecular gas mass tracers in galaxies, the $\rm ^{12}CO$(1-0), [CI]($^3P_1$-$^3P_0$) lines, and the submm dust continuum emission, using a sample of 407 galaxies, ranging from local disks to submillimetre-selected galaxies (SMGs) up to $z \approx 6$. A Bayesian method is used to produce galaxy-scale universal calibrations of these molecular gas indicators, that hold over 3-4 orders of magnitude in infrared luminosity, $L_{\rm IR}$. Regarding the dust continuum, we use a mass-weighted dust temperature, $T_{\rm mw}$, determined using new empirical relations between temperature and luminosity. We find the average $L/M_{\rm mol}$ gas mass conversion factors to be $α_{850}= 6.9\times10^{12}\,\rm W\,Hz^{-1}\,M_{\odot}^{-1}$, $α_{\rm CO} = \rm 4\,M_{\odot} (K\,km\,s^{-1}\,pc^2)^{-1}$ and $α_{\rm CI} = \rm 17.0 \,M_{\odot} (K\,km\,s^{-1}\,pc^2)^{-1}$, based on the assumption that the mean dust properties of the sample ($κ_H$ = gas-to-dust ratio/dust emissivity) will be similar to those of local metal rich galaxies and the MW. The tracer with the least intrinsic scatter is [CI](1-0), while CO(1-0) has the highest. The conversion factors show a weak but significant correlation with $L_{\rm IR}$. Assuming dust properties typical of metal-rich galaxies, we infer a neutral carbon abundance $X_{\rm CI} = [C^0/\rm mol]=1.6\times 10^{-5}$, similar to that in the MW. We find no evidence for bimodality of $α_{\rm CO}$ between main-sequence (MS) galaxies and those with extreme star-formation intensity, i.e. ULIRGs and SMGs. The means of the three conversion factors are found to be similar between MS galaxies and ULIRGs/SMGs, to within 10-20%. We show that for metal-rich galaxies, near-universal average values for $α_{\rm CO}$, $X_{\rm CI}$ and $κ_H$ are adequate for global molecular gas estimates.

description: A citologia por impressão é um método não invasivo útil para avaliar a superfície ocular. Consiste na aplicação de um fragmento de papel filtro sobre a conjuntiva. As amostras obtidas podem ter até três camadas de células e são distendidas em lâminas histológicas. O estudo teve como objetivo avaliar o padrão qualitativo e quantitativo das células da conjuntiva bulbar em bovinos e cavalos clinicamente saudáveis para facilitar o diagnóstico de doenças oculares externas. Para este fim, foram coletadas amostras de células externas da conjuntiva ocular pelo método de citologia de impressão de 15 bovinos e 15 equinos adultos. Para o exame citológico as amostras foram coradas por Giemsa e Shorr. Duas lâminas foram preparadas de cada animal, uma do olho esquerdo e outro do olho direito e foram contadas 800 células em total. Para a análise estatística, o ANOVA foi utilizado, foram considerados significativos os valores de p < 0,05. A análise permitiu estabelecer diferenças no numero de células caliciformes, linfócitos e eritrócitos entre espécies e animais. A citologia por impressão da conjuntiva bulbar foi eficaz na análise celular e foi bem aceita pelos bovinos e equinos.

description: O paraquat, herbicida amplamente utilizado na agricultura, é um produto tóxico, pois pode causar intoxicações fatais, principalmente pela falta de antídoto eficaz para reversão do quadro clínico. Os efeitos toxicológicos são decorrentes da indução ao stress oxidativo. O órgão alvo principal é o pulmão, que pode apresentar edema, hemorragia, inflamação intersticial e fibrose, culminando com falência respiratória grave e morte. Além disso, é nefrotóxico, hepatotóxico, miotóxico e neurotóxico. O tratamento da intoxicação além de visar a diminuição da absorção e estimular a excreção do paraquat absorvido, atualmente é baseado em medidas que diminuam o stress oxidativo utilizando substâncias antioxidantes e que, consequentemente, revertam o quadro toxicológico instalado, especialmente o pulmonar. Como métodos de diagnóstico, entre as metodologias quantitativas disponíveis, os métodos cromatográficos são os mais relatados para materiais biológicos. Porém, a electroforese capilar e os imunoensaios podem ser utilizados. Por outro lado, uma reação simples e rápida de caracterização urinária com ditionito de sódio é muito utilizada, pois é preditiva na suspeita de intoxicações agudas. Em conclusão, perante o alto potencial de morbimortalidade nas intoxicações por paraquat, a reversão dos danos pulmonares com uso de antioxidantes tem sido muito estudada, porém não há o estabelecimento de um antídoto específico. No diagnóstico laboratorial, métodos cromatográficos, eletroforéticos e imunológicos são usados para quantificá-lo, contudo a reação urinária com ditionito ainda é valiosa na rotina da toxicologia clínica.

description: Birds, both companion and wild, have become frequent patients in veterinary clinics and hospitals as well in wildlife rehabilitation centers in the last two decades. In emergency situations, it is imperative to give the best critical care to these patients, which frequently implies reversing shock and re-establishing homeostasis. In order to do so, a blood transfusion can be life-saving. It is important to the clinician to properly evaluate these critical patients and decide when to administer blood or blood products.

description: Uma fêmea da raça caniche de 15 anos com hiperadrenocorticismo, apresentou-se com descarga vulvar. Uma ecografia abdominal confirmou a existência de piómetra aberta. Foi executada uma ovariohisterectomia laparoscópica de forma a diminuir o local de incisão e limitar o risco de deiscência de sutura, frequentemente associada ao hiperadrenocorticismo. O tempo cirúrgico foi de 85 minutos e a cadela permaneceu no recobro por 3 horas sem complicações. A ovariectomia e ovariohisterectomia são frequentemente realizadas em fêmeas saudáveis, mas este procedimento também pode ser realizado em piómetras abertas sem aumentar a taxa de complicações pós-cirúrgicas. Neste caso, ao optar por esta abordagem cirúrgica, sendo uma fêmea geriátrica, com excesso de peso e com paredes abdominais de baixa resistência, foram limitadas potenciais complicações. O objectivo desta revisão literário-científica é dar a conhecer a evolução da cirurgia minimamente invasiva ao nível da ovariohisterectomia e ovariectomia, dando a conhecer as inovações e novas abordagens da laparoscopia neste tema.
