Published: July 2023

Volatile organic compounds (VOCs) emitted by plant foliage play an important role in ozone (O3) and secondary organic aerosol (SOA) formation. Their emissions can be influenced by the leaf age. We explored the VOCs emissions and their effects on the formation of O3 and SOA from plant foliage in different ages. VOCs emissions from the young, mature, and senescent leaves of Ginkgo biloba, Ligustrum lucidum, and Forsythia suspensa were measured using the dynamic enclosure system and the TD–GC–MS technique. Based on the emission rates of quantified compounds, their potential to form O3 and SOA was estimated. Results showed that there were significant differences in the VOCs emission rate and their composition among leaves in different ages. The emission rate of the total VOCs by young leaves was the highest, while the lowest by senescent leaves. Monoterpenes were the dominant VOCs category, and isoprene emission had the lowest contribution for the leaves at each age. With increasing leaf age, the proportion of monoterpenes emission increased, and the proportion of sesquiterpenes decreased. The variations of isoprene and other VOCs were different. The potentials of total VOCs, isoprene, monoterpenes, sesquiterpenes, and other VOCs to form O3 (OFP) and SOA (SOAP) varied significantly among leaves at different ages. The total OFP and SOAP were the highest by young leaves, while the lowest by senescent leaves. With increasing leaf age, the contribution of monoterpenes to OFP and SOAP also increased, while that of sesquiterpenes decreased. Our study will provide support for the more accurate parameterization of the emission model and help to understand the VOCs emissions and study the precise prevention and control of complex air pollution at different times.

Published: July 2023

Aflatoxins are potent carcinogenic compounds, mainly produced by fungi species of the genus Aspergillus in the soil. Because of their stability, they are difficult to remove completely, even under extreme conditions. Aflatoxin contamination is one of the main causes of safety in peanuts, maize, wheat and other agricultural products. Aflatoxin contamination originates from the soil. Through the investigation of soil properties and soil microbial distribution, the sources of aflatoxin are identified, aflatoxin contamination is classified and analysed, and post-harvest crop detoxification and corresponding contamination prevention measures are identified. This includes the team’s recent development of the biofungicide ARC-BBBE (Aflatoxin Rhizobia Couple-B. amyloliquefaciens, B. laterosporu, B. mucilaginosus, E. ludwiggi) for field application and nanomaterials for post-production detoxification of cereals and oilseed crops, providing an effective and feasible approach for the prevention and control of aflatoxin contamination. Finally, it is hoped that effective preventive and control measures can be applied to a large number of cereal and oilseed crops.

Published: July 2023

The studies carried out to date on vulvodynia treatment with botulinum neurotoxin type A (BoNT/A) have followed generic injection protocols and reported contradictory outcomes on its effects. The aim of the present study was thus to propose a protocol for injecting BoNT/A into targeted painful points, to comprehensively assess the clinical effect of BoNT/A treatment and identify the risk/protective factors for successful treatment. Thirty-five vestibulodynia patients were treated with submucosal injections of incobotulinumtoxinA and assessed 8, 12 and 24 weeks after their treatment. Their clinical and pelvic statuses were assessed from self-reported questionnaires (Visual Analogue Scale (VAS), Female Sexual Function Index (FSFI), Marinoff’s Dyspareunia Scale (MDS), Hospital Anxiety and Depression Scale (HADS), Catastrophizing Scale (CS)), physical examinations and surface electromyography (sEMG). The patients reported a reduction in provoked vestibulodynia (<VAS, p < 0.01), improved sexual function (>FSFI, p < 0.01; <MDS, p = 0.01) and psychological status (<HADS, p < 0.01), and lower pelvic floor hyperactivity at rest (<sEMG amplitude, p = 0.01). Factors such as smoking, painful comorbidities, vulvar pain sensitivity and sexual function were significantly associated with successful treatment. The results indicate the beneficial effects of BoNT/A in treating vestibulodynia and reinforce the importance of adapting the treatment according to its clinical presentation and the patient’s medical background.

The Zika virus (ZIKV) is a widespread mosquito-borne pathogen. Phylogenetically, two lineages of ZIKV are distinguished: African and Asian–American. The latter became the cause of the 2015–2016 pandemic, with severe consequences for newborns. In West African countries, the African lineage was found, but there is evidence of the emergence of the Asian–American lineage in Cape Verde and Angola. This highlights the need to not only monitor ZIKV but also sequence the isolates. In this article, we present a case report of Zika fever in a pregnant woman from Guinea identified in 2018. Viral RNA was detected through qRT-PCR in a serum sample. In addition, the seroconversion of anti-Zika IgM and IgG antibodies was detected in repeated blood samples. Subsequently, the virus was isolated from the C6/36 cell line. The detected ZIKV belonged to the African lineage, the Nigerian sublineage. The strains with the closest sequences were isolated from mosquitoes in Senegal in 2011 and 2015. In addition, we conducted the serological screening of 116 blood samples collected from patients presenting to the hospital of Faranah with fevers during the period 2018–2021. As a result, it was found that IgM-positive patients were identified each year and that the seroprevalence varied between 5.6% and 17.1%.

Published: July 2023

Clinical cases of ‘staggering disease’, a nonsuppurative encephalomyelitis associated with gait abnormalities in cats, have been documented for decades in Sweden. In Austria, an increased incidence was observed in the 1990s. Only recently, rustrela virus (RusV) was identified as the causative agent of this clinicopathologic disease entity. In this retrospective study, we analyzed a total of 23 brain and spinal cord samples from Austrian cats with the pathohistological diagnosis of nonsuppurative encephalomyelitis and clinical signs consistent with staggering disease from 1994 to 2016 using reverse transcription real-time polymerase chain reaction (RT-qPCR) and in situ hybridization. We were able to detect RusV nucleic acids in seven of the examined samples. Borna disease virus 1 (BoDV-1) could be excluded in all cases via immunohistochemistry and RT-qPCR. This study confirms that RusV has been a relevant etiological agent of nonsuppurative encephalomyelitis of cats in a geographically and temporally limited disease cluster in Austria, mainly in the 1990s. The geographic distribution of the positive samples in this study is consistent with earlier reports on ‘staggering disease’ in Austria. Further studies are necessary to confirm the reservoir host of ‘staggering disease’ in Austria, as well as investigations on the disappearance of this disease and its possible zoonotic potential.

Published: July 2023

The spread of lumpy skin disease (LSD) to free countries over the last 10 years, particularly countries in Europe, Central and South East Asia, has highlighted the threat of emergence in new areas or re-emergence in countries that achieved eradication. This review aimed to identify studies on LSD epidemiology. A focus was made on hosts, modes of transmission and spread, risks of outbreaks and emergence in new areas. In order to summarize the research progress regarding the epidemiological characteristics of LSD virus over the last 40 years, the Preferred Reporting Items for Systematic reviews and Meta-Analyses statement guidelines were followed, via two databases, i.e., PubMed (biomedical literature) and Scopus (peer-reviewed literature including scientific journals, books, and conference proceedings). A total of 86 scientific articles were considered and classified according to the type of epidemiological study, i.e., experimental versus observational. The main findings and limitations of the retrieved articles were summarized: buffaloes are the main non-cattle hosts, the main transmission mode is mechanical, i.e., via blood-sucking vectors, and stable flies are the most competent vectors. Vectors are mainly responsible for a short-distance spread, while cattle trade spread the virus over long distances. Furthermore, vaccine-recombinant strains have emerged. In conclusion, controlling animal trade and insects in animal transport trucks are the most appropriate measures to limit or prevent LSD (re)emergence.

The pneumococcal conjugate vaccination (PCV) was introduced into the Brazilian Childhood National Immunization Program in 2010; however, universal pneumococcal vaccination for older adults has not been implemented yet. Our aim is to evaluate the trends in pneumococcal meningitis incidence and case fatality rate (CFR) across all age groups from 2007 to 2019 using data from the National Surveillance System. The pre-PCV (2007–2009) and post-PCV (2011–2019) periods were compared; changes in incidence and CFR were assessed by joinpoint regression. Additional analyses of bacterial meningitis were performed to compare the patterns and trends. Over the 13-year period, 81,203 and 13,837 cases were classified as bacterial and pneumococcal meningitis, respectively. S. pneumoniae was the main etiological agent of bacterial meningitis in adults aged ≥50 years and the most lethal in all age groups. In the post-PCV period, a 56.5% reduction in the average incidence was seen in pneumococcal meningitis in the pediatric population. In contrast, there was an increasing trend among adults. The CFR for pneumococcal and bacterial meningitis remained stable in most age groups during the study period. These findings highlight the value of expanding pneumococcal vaccination policies, including vaccines that provide better indirect protection from children to adults and broadening vaccination to older adults.
Cocaine Effects on Reproductive Behavior and Fertility: An Overview
Authors: Rosati Luigi , Chianese Teresa , Mileo Aldo , De Falco Maria , Capaldo Anna
Published: July 2023

Cocaine is one of the most widely used drugs that, due to its molecular properties, causes various behavioral alterations, including sexual behavior. In vivo and in vitro studies conducted mainly in mammals have shown various disorders of sexual activity and morpho-functional dysfunctions of the gonads in both sexes. Although the modalities are still unclear, cocaine has been shown to alter the cell cycle, induce apoptosis, and alter sperm motility. In females, this drug alters the formation of the meiotic spindle as well as may obstruct the ovulation mechanism of mature oocytes. The data provided in this review, in addition to reviewing the current literature on the main effects of cocaine on spermatogenesis and oogenesis mainly in mammals, will hopefully provide a basic overview that may help and support further future studies on the molecular interaction of cocaine and its metabolites with germ cells.
Identification of Sedimentary Environments through Dynamic Image Analysis of the Particle Morphology of Beach Sediments on the East and West Coasts of Hainan Island in South China
Authors: Cheng Wufeng , Chen Shenliang , Zhong Xiaojing , Zhao Shaohua
Published: July 2023

Particle morphology is an important feature of sediments that reflects their transport history and depositional environment. In this study, we used dynamic image analysis (DIA) to measure the size and shape of beach sediments on the east and west coasts of Hainan Island in South China Sea. DIA is a fast and accurate method that can capture and analyze a large number of sediment particles in real-time. We extracted morphological descriptors of each particle, such as equivalent diameter, sphericity, aspect ratio and symmetry, and their distributions based on volume and number. We performed multivariate analysis on the particle morphological data, including alpha diversity, statistical analysis and fingerprint techniques. We found that the Shannon index, calculated by the number distribution of sediment particle morphology, can effectively discriminate between the two sites, reflecting different sediment sources, transport processes and depositional conditions. We also established a composite fingerprint based on seven morphological parameters and diversity indices, which can accurately distinguish between aeolian and hydraulic sedimentary environments. Our study demonstrates the potential application of DIA in identifying sedimentary environments and establishing sediment fingerprints. This can help us understand the sediment transport processes and depositional mechanisms in coastal areas.
Experimental Study on the Hydrodynamic Characteristics of a Fixed Comb-Type Floating Breakwater

Published: July 2023

A comb-type floating breakwater is a new wave dissipation structure with particular force and dissipation performance advantages due to the two wave-reflecting surfaces. In this article, physical model experiments are used to study the hydrodynamic characteristics of a fixed floating comb breakwater and two structural optimization-based measures under the combined action of regular waves, irregular waves, and wave currents. The effects of factors such as the relative width, relative wave height, water flow velocity, and irregular waves on the transmission coefficient of the breakwater are analyzed. In addition, the characteristics of the transmission wave waveform are analyzed based on the time and frequency domains. The results show that (1) the wave transmission coefficient of a comb-type floating breakwater is lower than that of a rectangular floating box for long-period waves, while the transmission coefficient is larger than that of a rectangular floating box for short-period waves. (2) Under combined current and waves, the superimposition of bidirectional currents can increase the transmission coefficient, and the transmission coefficient increases with increasing current speed. The superimposition of the anti-directional current can decrease the transmission coefficient. (3) Moreover, with the same wave parameters, the transmission coefficient for irregular waves is larger than that of regular waves. (4) Finally, extending the bottom plate and adding lower baffles can effectively enhance the wave dissipation effect of the comb-type floating breakwater while also stabilizing the transmitted wave waveform.

Published: July 2023

The present study sought to expand the now expansive research on COVID-19 by examining COVID-19-related fear among adolescents in Israel, focusing on demographic variables, COVID-19-related variables (e.g., exposure and vaccination), psychosocial variables (e.g., adolescent wellbeing and perceived social support), and technology usage (e.g., amount of time spent on social media). Data from parents were also collected, reflecting parental attitudes toward the pandemic, anxiety and depression, and wellbeing. A total of 150 youth aged 12–18 and 150 parents participated in the study. Findings indicated that being a female, having a parent who knew someone who had died from COVID-19, and never having tested positive for COVID-19 were positively associated with increased fear of COVID-19. Increased fear of being infected with COVID-19 was also associated with high levels of anxiety and depressive symptomatology in both youth and parents and with low parent subjective wellbeing. Youth who used social media for sharing experiences and for politics also reported such fear. Youth whose parents reported that the media exaggerated COVID-19 risks were less likely to fear something bad would happen to them or to a loved one or fear another outbreak of the virus. Our findings call for paying further scholarly and professional attention to the role intrapsychological, interpersonal, and social aspects play in processes of increased fear and wellbeing in adolescents who constitute a particularly vulnerable group to the mental health consequences of the pandemic.

Published: July 2023

El presente artículo pretende identificar los modelos de incubadoras que se utilizan en la educación superior hondureña, tomando como base los dos modelos teóricos puros que plantea Bolla-ti (2015), modelo de incubación tradicional y el modelo de incubación de base tecnológica, para la definición de dichos modelos se toma en consideración una serie de variables planteadas como buenas prácticas de incubadoras definidas en Nodriza (2005), como ser modelo operacional, tipo de servicio, financiamiento, tipo de redes, modelo de negocios y estatus legal de la incuba-dora.

La investigación se realizó con un enfoque cualitativo, bajo un diseño exploratorio utilizando la metodología del estudio de casos múltiples (Yin, 2009). La recolección de datos se llevó a cabo en 2 etapas, la primera etapa incluyó la revisión de artículos científicos y las Webs oficiales de las universidades, y la segunda etapa consistió en entrevistas con responsables de las incubadoras de empresas, mediante un formato de conversación guiada.

Dentro de los resultados encontramos que cinco de veinte universidades hondureñas tienen una incubadora de empresas funcionando, el siguiente hallazgo que la investigación nos revela es que el modelo de incubación prevaleciente es el tradicional.

Como conclusiones se estima que el ecosistema emprendedor a nivel de la educación superior en Honduras, se encuentra aún en fases iniciales, con criterios de admisión bien establecidos y enfocados en emprendedores de sus mismas universidades, dependientes de sus espacios físicos y las redes que se generen alrededor de estos, y en donde aún, no se ha podido comenzar el proceso de transformación hacia incubadoras virtuales.

Published: July 2023

Using client-based Extension projects in university community planning studio courses is an expedient solution that matches needs with resources. However, the decision to partner should be based primarily on students achieving expected learning outcomes. Cautious Extension agents will rarely introduce students to wicked problems or expose students to the mechanics of project initiation, and yet this is exactly what community planning studios should be doing. This article offers recommendations to help determine the selection and structuring of Extension projects for use in the classroom.

Published: July 2023

China’s Tiangong space station has been completed in 2022 to support large-scale multidisciplinary space science research and technology experiments. With a large payload capacity and long operating time, Tiangong space station has many irreplaceable advantages over other spacecraft, such as space transportation, global tracking, on-orbit care for astronauts, and the ability to replace and upgrade experiment equipment. The resources available to the space station and its affiliated spacecraft provide an excellent open verification platform for experimental programs. The modular design of the intravehicular experiment rack can support different combinations of normal payloads for experiment, and an extravehicular exposed platform is planned to support different sizes of normal payloads for experiment. This paper firstly discusses the mission objectives of China’s Tiangong space station and the development of new space systems. Secondly, it sorts out the conditions for China’s Tiangong space station to conduct experiments for space technology. On this basis, a systematic layout for the missions of space technology experiments on China’s Tiangong space station is made. Five research topics are proposed, i.e., robotics and autonomous system technology, on-orbit assembly and construction technology for spacecraft, environmental control and life support system technology, new energy and propulsion technology, and new generic technology for spacecraft. Centering on the key technologies that restrict the development of China’s future space missions and systems, this study gives an outlook on the on-orbit space technology experiment and verification project for China’s Tiangong space station. Finally, development strategy and suggestions are put forward for China’s space technology.

A raiva é uma enfermidade zoonótica causada por um vírus envelopado da família Rhabdoviridae, responsável por alterações neurológicas progressivas e fatais. A transmissão se dá pela exposição à saliva de animais infectados. O diagnóstico oficial de raiva é feito pela técnica de imunofluorescência direta. O objetivo desse estudo foi descrever um caso de raiva em um equino na região do Vale do Rio Doce/MG abordando seus aspectos epidemiológicos e clínico-patológicos. Foi atendido um equino, fêmea, Manga Larga Marchador, de um ano e meio de idade, proveniente do município de Resplendor/MG, Vale do Rio Doce, com decúbito lateral, sudorese intensa, nistagmo e movimentos de pedalagem há dois dias. Devido a uma queda. O animal morreu e o sistema nervoso central foi retirado e encaminhado pare análise. Histologicamente observou-se encefalite não supurativa sugestiva de raiva. No teste de imunofluorescência direta, houve detecção de antígenos virais de raiva, confirmando o diagnóstico definitivo da doença nesse equino. É importante ressaltar que esse cavalo havia recebido uma única dose da vacina de raiva. Entretanto, casos de raiva têm sido descritos em animais que receberam apenas uma única dose da vacina. Além disso, este caso ocorreu na região do vale do Rio Doce, no estado de Minas Gerais. Esse estado é considerado endêmico para raiva. Tem sido mencionado que a manutenção da doença nesta região está associada a introdução de animais domésticos, o desmatamento do bioma Mata Atlântica e a urbanização das áreas rurais. Chama a atenção, que recentemente nessa mesma região (Vale do Rio Doce) foi noticiado um caso de raiva humana transmitida por herbívoro.

Atividades antrópicas modificam e reduzem ambientes naturais, fragmentando ecossistemas e afetando a riqueza, distribuição e abundância das espécies de aves. Este trabalho objetivou observar a avifauna em três fragmentos remanescentes de Mata Atlântica, no Instituto Federal do Sudeste de Minas Gerais, Campus Barbacena. As aves foram observadas com binóculos, câmeras fotográficas e playback (gravação de vocalização de aves específicas), nos períodos matutinos e vespertinos, de maio/2018 a janeiro/2019. Pelo método Mau Tau estimou-se a riqueza e curva de rarefação e pelo coeficiente de similaridade de Jaccard estimou-se a distribuição das espécies nos três fragmentos. Calculou-se a abundância nos fragmentos pela frequência de cada espécie dividida pelo total de saídas a campo. A riqueza estimada foi de 76 espécies, 32 famílias e 14 ordens, sendo 13 espécies endêmicas da Mata Atlântica. A curva de rarefação tendeu a não estabilidade, demostrando necessidade de mais coletas de dados. A distribuição e composição de espécies mais similares (J = 0,455). Há similaridade na composição e distribuição de espécies observadas nos fragmentos F01 e F02. No F01 observou-se Scytalopus iraiensis, endêmica da Mata Atlântica e ameaçada de extinção. Das 76 espécies, 18 foram abundantes, oito frequentes, 11 comuns e 39 acidentais. A maior abundância nos três fragmentos foi a Psittacara leucophthalmus e a guilda alimentar insetívora. Os fragmentos preservavam espécies da Mata Atlântica (76), endêmicas (13) e ameaçada de extinção (01). Esforços de proteção desses remanescentes minimizam os impactos na avifauna da Mata Atlântica.

The presence of hydroxylated metabolites of aflatoxin B1 (AFB1), such as M1 (AFM1) Aflatoxin has been reported in breast laying hen, Diaz Zaragoza et al, 2014. The hens when their laying cycle end are sent to the trail of bird for his sacrifice. In Mexico chicken consumption in the form of stock, it is much in demand mainly in the center and southeast of the country. Some companies process meat to prepare various types of sausages, such that in one way or another becomes a food for human consumption. Currently the System Product Poultry in Mexico, is working to raise awareness about food safety in the poultry industry generated as egg and meat. The AFM1 is a compound considered as a carcinogen and is limited in milk at levels of 0.5 to 0.05 µg/L. This depend the regulations of each region of the world. The given the possibility that AFM1 is a chemical risk consumption of hen breast. Evaluating the Bio-transfer this AFB1 was performed in a contaminated diet with 500 µg/kg (ppb) and quantify AFM1 contamination in the breast, after 8 days of diet consumption. At the same time included an anti-aflatoxin agent to verify their efficiency in this experiment. AFM1 concentration in the breast of the negative control group was below the detection limit of 0.001 ppb. The concentration of the positive control group was 0.004 ppb and challenge group concentration was 0.002 ppb. The analytical tests were carried out by the technique of Ultra High Performance Liquid Chromatography (UHPLC). The results show that bio-AFB1 transfer to the breast as AFM1 is minimal. Therefore, this food is considered safe. Evaluated adsorbent efficiency was 50%. Complementarily AFB1 concentration in the liver, where the toxin is quantified levels of 0.467 ppb in the positive control and 0.196 ppb in the challenge group with adsorbent was evaluated. The effectiveness of the commercial adsorbent was the 60%.

El clenbuterol-Clb calificado como un potente bronco-vaso-dilatador, repartidor de grasa, agente tocolitico (retardador del parto), utilizado para controlar enfermedades respiratorias, tanto en animales como en humanos; el Clb es un β2-agonista-adrenérgico (β2-AA), el cual, causa incremento de la masa muscular en aves,  bovinos, cabras y ovejas, sin embargo, las rutas metabólicas y el modo de acción hasta el presente no están bien dilucidadas; el objetivo de este estudio consistió en determinar los metabolitos que surgen con la ingesta del clembuterol y sus `posibles derivados que se almacenan en la estructura hepática, páncreas, glándula suprarrenal, músculos y órganos genitales en bovinos. Además, se sabe que el contenido de grasa es reducido dramáticamente cuando el clembuterol es utilizado como anabólico, entendiendo como anabólico, cuando el Clb se administra de forma oral o intramuscular por arriba de la dosis terapéutica, entre 5 y 10 veces su concentración terapéutica (0.8µg/peso corporal dos veces al día). Para este estudio de midieron 17 metabolitos diferentes con el propósito de determinar cuáles son los parámetros metabólicos que son perturbados por este aditivo, y que impiden los procesos de equilibrio intra y extracelular llamado homeostasis, esto a nivel de los diferentes órganos en el que interviene. Se estudiaron 2567 bovinos: el 95% machos y el 5% hembras (Bos taurus X Bos indicus), los resultados revelaron que son varios los metabolitos que son alterados por el clembuterol entre estos tenemos a: a la glucosa, triglicéridos, colesterol, bilirrubina y el Calcio y enzimas a nivel hepático como: fosfatasa alcalina, gamma glutamil transferasa, transaminasas (ALT/GPT y AST/GOT), deshidrogenas láctica; fosfatasa acida: FA-total, FA-prostático y FA-no prostática, los datos muestran que el Clb tiene un efecto en alterar el metabolismo de varias rutas metabólicas; contribuyendo a que posee actividad lipolítica, y anti-lipogénicas e induce a la retención de nitrógeno, aumenta la glicolisis, la producción de lactato y el consumo de oxígeno, incrementa los niveles de glucosa, que varía de acuerdo al tiempo de tratamiento o que es suministrado, ya que a nivel del páncreas disminuye la insulina y los adipocitos son menos sensibles a este aditivo, se detectó el incremento en la utilización de energía y esto produce el aumento de la temperatura corporal llamada termogénesis y que repercute en el desarrollo de patologías en la calidad espermática de los bovinos e infertilidad en hembras bovinas a nivel hormonal, también aumenta los intervalos entre partos-anestro; estas anomalías  desarrolladas son activadas por el uso de este aditivo alimenticio Clb. Estos datos determinan que este aditivo tiende a disminuir la sustentabilidad de esta especie.

O biochar material produzido a partir da pirólise de materiais lignocelulósicos, pode contribuir para aumento da fertilidade, melhoria da disponibilidade de nutrientes e favorecer a atividade microbiana do solo, em específico a influenciar a simbiose micorrízica arbuscular. O objetivo deste trabalho foi avaliar a influência de doses de biochar produzido a partir da serragem de eucalipto, na simbiose micorrízica arbuscular de fungos nativos presentes no solo do bioma cerrado. O delineamento experimental aplicado foi inteiramente casualizado, com quatro tratamentos e cinco repetições, correspondendo a doses de biochar (0, 5, 10 e 15 % m/m). Utilizou-se a gramínea (Panicum miliaceum L.) em LATOSSOLO VERMELHO distrófico e após trinta dias foram avaliados a densidade de esporos (DE), porcentagem de colonização radicular (Col), pH, condutividade elétrica (CE) e respiração basal do solo (RBS). O biochar proporcionou aumento nos valores de pH e DE em função das doses de biochar, apresentando diferença significativa pelo teste de tukey (p<0.05) em relação ao tratamento sem adição de biochar, o inverso ocorreu para RBS. Já para as variáveis CE e Col, ocorreu o aumento e redução em função das doses, respectivamente. Os resultados permitiram verificar que o biochar da serragem de eucalipto favoreceu a simbiose FMA nativos, além de garantir a redução da acidez e não provocar o aumento da condutividade elétrica do solo.

La utilización de tecnologías amigables con el medio ambiente como las tecnologías de tratamiento de aguas residuales no convencionales son una alternativa para poblaciones descentralizadas. Los humedales subsuperficiales de flujo vertical son un ejemplo de ello, estos sistemas utilizan sustratos emergentes según la disponibilidad del recurso en el área de implantación, tienen bajos costes de operación y mantenimiento y no requieren de personal especializado. En la presente investigación a escala de microcosmo se evalúa la remoción de materia orgánica y nutrientes de un agua residual urbana, mediante una planta piloto de flujo vertical implantada con sustrato (grava gruesa, roca volcánica, grava fina y una mezcla de turba con abono orgánico) y plantada con la macrófita de la especie Iris pseudacorus. Se realizaron ensayos con tasas de carga hidráulica que oscilaron entre 0.2 y 3 L min-1 y su eficiencia se evaluó mediante el análisis de NH4+, Fe, Ca, Al, P, Cl- libre y total, DBO5 y sólidos presentes. Obteniendo la mayor eficiencia de remoción de DBO con  0.2 L min-1 removiendo el 84%, mientras, para NH4+ y PT con el 60% y 42% respectivamente. Las tasas de remoción promedio de SST y ST fue del 71 y 65%, mientras para Ca, Fe y Al del 80, 53 y 63% respectivamente. Se concluye que es factible utilizar esta tecnología con Iris Pseudacorus en el tratamiento de agua residuales.

In the clinical routine, blood tests are of paramount importance for the assessment of the health of animals, as they allow the quantification of red and white blood cells, and thus enable the detection and monitoring of hematological changes caused by diseases of parasitic origin. Because of the above, the objective of this work is to describe the main hematological alterations in canines with blood diseases of parasitic origin. A retrospective study was carried out of the medical records of dogs referred and treated by the outpatient team of the Laboratory of Parasitic Diseases of Animals of the Veterinary Clinic School of the Federal University of Sergipe, Campus do Sertão, from March 2022 to December 2022, all statistical data were analyzed using the InStat GraphPad software, with a significance level of p<0.05. As a result, it was observed that 30% (18/60; p<0.0001) of the dogs had blood diseases of parasitic origin. 5,55% (1/18; p<0.0001) of patients were diagnosed with anaplasmosis, 5,55% (1/18; p<0.0001) with ehrlichiosis, 11,11% (2/18; p<0.0010) with babesiosis, 5,55% (1/18; p<0.0001) with hepatozoonosis and 77,77% (14/18; p<0.0003) with leishmaniasis. Monoparasitism and co-infection were observed in 94.44% and 5.56% of the animals, respectively (p<0.0001). Anemia, anisocytosis, leukocytosis, lymphocytosis and, thrombocytopenia were the main hematological changes observed in parasitized dogs.

O envenenamento por picada de cobra é uma condição que afeta seres humanos e animais em todo mundo. No Brasil, as serpentes venenosas existentes pertencem aos gêneros Bothrops, Crotalus, Lachesis e Micrurus. Contudo, os acidentes botrópicos são os mais frequentemente descritos na medicina humana e veterinária. Assim, o objetivo desse estudo foi descrever um caso de acidente botrópico em um cão na região noroeste do Espírito Santo, destacando suas características clínico-laboratoriais. Foi atendido um canino, macho, castrado, sem raça definida (SRD), de 1 ano de idade, proveniente da zona rural do município de Pancas, região noroeste do Espírito Santo, com suspeita de picada de cobra do gênero Bothrops. O animal apresentava sangramento e algia intensa em membro torácico direito. Foi realizada a administração do soro antiofídico e fármacos analgésicos, antibióticos, anti-inflamatórios e hemostáticos. Nos exames laboratoriais, o paciente apresentou anemia intensa, hipoproteinemia, leucocitose por neutrofilia e trombocitopenia, além de hipoalbuminemia e aumento nas concentrações fosfatase alcalina e ureia. O diagnóstico de acidente ofídico por cobra do gênero Bothrops baseou-se nas alterações clínico-laboratoriais típicas e pela visualização da serpente pelo tutor. A alta incidência de acidentes botrópicos no Brasil ocorre devido à vasta distribuição geográfica das serpentes no país. Os sinais clínicos e as alterações hematológicas e bioquímicas observadas nos animais ocorrem devido a diversas enzimas, peptídeos e proteínas presentes no veneno que causam os efeitos deletérios locais e sistêmicos descritos. A terapia consiste, principalmente, na administração do soro antiofídico e fármacos adjuvantes para controle dos efeitos locais. Chama-se a atenção que as estatísticas de acidentes ofídicos na medicina veterinária baseiam-se principalmente em relatos de casos ou estudos feitos nos centros de diagnósticos das universidades do país, devido a não obrigatoriedade da notificação desses acidentes.

La detección precisa es importante para una respuesta rápida a los Accidentes por Derrame de Petróleo (ADP). La investigación tiene como objetivo determinar el nivel de riesgo originado por derrame de petróleo en zonas costeras de Lima y Callao. Se consideraron nueve indicadores espaciales para el proceso de mapeo: Corriente marina; dirección del viento; concentración de derrame de petróleo; lugar de ocurrencia; unidad de conservación; uso actual del suelo; microzonificación ecológica económica; tipo de suelo; geomorfología. Se identificó utilizando un enfoque integrado de Tecnologías de Información Geográfica (TIG), Proceso Analítico Jerárquico (AHP) basado en la toma de decisiones multicriterio. Los resultados revelaron la Zonificación del Riesgo (ZR) originado por ADP: Muy Alto (ADPMA) con 0.244 ≤ ZR ≤ 0.488; Alto (ADPA) con 0.153 ≤ ZR ≤ 0.244; Medio (ADPM) con 0.073 ≤ ZR ≤ 0.153 y Bajo (ADPB) con 0.043 ≤ R ≤ 0.073. La cartografía de riesgo ayudará a las instituciones a formular políticas y a los planificadores a implementar medidas de mitigación efectivas para evitar futuros derrames.
