Authors: Albe-Slabi Sara , Mesieres Odile , Mathé Christelle , Ndiaye Mbalo , Galet Olivier , Kapel Romain
Published: June 2022

Lupin meal presents great potential as an alternative plant-based source of proteins for human nutrition. In the present work, different conditions of extraction and purification were evaluated for production of lupin protein isolates. The results showed that the protein extraction yield was comparable at acidic and conventionally used alkaline extraction pH (37% vs. 40–45%, respectively). Proteins extracted were principally composed of globulins. The ionic strength negatively impacted the protein extractability at pH 2, whereas no significant differences were observed between extractions at 20 to 50 °C. The selected extraction conditions (pH 2 and 7) combined with purification by isoelectric precipitation or ultrafiltration process generated the isolate-grade products. Interestingly, further characterization revealed a partial denaturation of proteins extracted at pH 2 resulting in loss of protein solubility at pH 6 and 7 (10–50%), modifications in secondary structure, lower thermal stability, and formation of protein aggregates. However, foaming and emulsifying properties were generally similar for almost all lupin isolates. Further investigation might be of interest with regard to the extraction behaviours and structural and functional properties of specific lupin protein fractions.

Authors: Fakieh Bahjat , AL-Ghamdi Abdullah S. AL-Malaise , Ragab Mahmoud
Published: June 2022

Osteosarcoma is a kind of bone cancer which generally starts to develop in the lengthy bones in the legs and arms. Because of an increase in occurrence of cancer and patient-specific treatment options, the detection and classification of cancer becomes a difficult process. The manual recognition of osteosarcoma necessitates expert knowledge and is time consuming. An earlier identification of osteosarcoma can reduce the death rate. With the development of new technologies, automated detection models can be exploited for medical image classification, thereby decreasing the expert’s reliance and resulting in timely identification. In recent times, an amount of Computer-Aided Detection (CAD) systems are available in the literature for the segmentation and detection of osteosarcoma using medicinal images. In this view, this research work develops a wind driven optimization with deep transfer learning enabled osteosarcoma detection and classification (WDODTL-ODC) method. The presented WDODTL-ODC model intends to determine the presence of osteosarcoma in the biomedical images. To accomplish this, the osteosarcoma model involves Gaussian filtering (GF) based on pre-processing and contrast enhancement techniques. In addition, deep transfer learning using a SqueezNet model is utilized as a featured extractor. At last, the Wind Driven Optimization (WDO) algorithm with a deep-stacked sparse auto-encoder (DSSAE) is employed for the classification process. The simulation outcome demonstrated that the WDODTL-ODC technique outperformed the existing models in the detection of osteosarcoma on biomedical images.
How Do Dongba Glyphs Transcribe IPA? Analysis of a Note by a Ruke Dongba Priest Learning IPA
Authors: Xu Duoduo
Published: June 2022

Dongba script is one of the very few pictographic writing systems still surviving in the world. The script evolved over time, and this is reflected by the correspondence between its written symbols and the related spoken language. During my fieldwork, I witnessed occasionally when Dongba glyphs have been analysed to write down IPA symbols based on Latin alphabet. This is an innovative application of Dongba pictographs, through the use of traditional scriptures and vernacular documents. This study provides insights into processes of adaptation in situations of contact between the Dongba pictographic writing system and the International Phonetic Alphabet and aims to shed light on structural issues pertaining to the phonological units of the Naxi language. According to the present research, Dongba glyphs can identify initials quite efficiently, yet they are not efficient in distinguishing rhymes and tones. At the same time, a phonemic chart written in Dongba glyphs shows to be a valuable tool to double-check the phonemic system. Moreover, some sound changes of Ruke Naxi are attested and assessed in this note.
Hand Washing: When Ritual Behavior Protects! Obsessive–Compulsive Symptoms in Young People during the COVID-19 Pandemic: A Narrative Review
Authors: Demaria Francesco , Pontillo Maria , Di Vincenzo Cristina , Di Luzio Michelangelo , Vicari Stefano
Published: June 2022

The Coronavirus Disease 2019 (COVID-19) pandemic had a profound impact on the lifestyles and mental health of young people. It has been hypothesized that the focus on hygiene and the fear of contamination/infection during the pandemic may have exacerbated obsessive–compulsive (OC) symptoms in this population. OC symptoms are widespread in the general population, with varying degrees of intensity. At their most extreme, they manifest in obsessive–compulsive disorder (OCD), which is characterized by obsessive thoughts and compulsive behaviors. The present narrative review aimed at evaluating the relationship between the COVID-19 pandemic and OCD and OC symptoms in young people, especially children and adolescents with and without OCD, focusing on vulnerability and risk factors and the impact of lockdown measures. Of the six studies identified, four examined clinical samples diagnosed with OCD and two looked at community-based adolescent samples. Five of the six studies found that OC symptoms increased during the pandemic. Additionally, vulnerability to anxiety may constitute a risk condition and the lockdown measures and personal stressful life events can constitute potential triggers of OC symptoms, while ongoing treatment for OCD had a protective effect. The results suggest that, during the COVID-19 pandemic, obsessive and compulsive behavior (e.g., hand washing) in young people at the greatest risk should be monitored, and the intervention of mental health services should be maintained. More research is needed in this area.

Published: June 2022

The plastic hinge is the most critical damaging part of a structural element, where the highest inelastic rotation would occur. In particular, flexural members develop maximum bending abilities at that point. The current paper experimentally investigates the influence of steel fiber reinforcement at the plastic hinge length of the concrete slab under repeated loading, something which has not been reported by any researcher. Mechanical properties such as compressive strength and tensile strength of M20-grade concrete that are used for casting specimens are tested through the compressive strength test and the split tensile strength test. Six different parameters are considered in the slab while carrying out this study. First, the conventional concrete slab and then the steel-fiber-reinforced slab were cast. The plastic hinge length of the slab was calculated through different empirical expressions taken from methods by Baker, Sawyer, Corley, Mattock, Paulay, Priestley and Park. Finally, the steel fiber was added as per methods detailed by Paulay, Priestley and Park in the plastic hinge length mechanism in the concrete slab at 70 mm and 150 mm separately. The results arrived through experimental investigation by applying repeated loads to the slab, indicating that steel fibers used at critical sections of plastic hinge length provide similar strength, displacement, and performance as that of the conventional RCC slab and fully steel-fiber-reinforced concrete slabs. Steel fiber at a plastic hinge length of slab has a better advantage over a conventional slab.

Published: June 2022

Silver nanoparticles (AgNs) are known as a promising alternative tool to control fungal diseases. AgNs were biologically synthesized using Trichoderma harzianum filtrate as an ecofriendly approach. The presence of AgNs was confirmed by changing the color to brown, followed by UV-Vis spectroscopy, transmission electron microscopy (TEM), and Energy-dispersive spectra (EDS). TEM studies showed that the size of AgNs average was 31.13 nm and the shape was spherical. In vitro assays of AgNs showed a significant inhibitory effect on the growth of Sclerotinia sclerotiorum (S. sclerotiorum) and Sclerotium rolfsii (S. rolfsii). The percentage inhibition on mycelial linear growth, dry weight, and sclerotia formation of S. sclerotiorum and S. rolfsii at 100−L were 87.8, 82.7, 96.4, 52.8, 55.1, and 85.4%, respectively. The obtained results suggested that the biosynthesized AgNs have antifungal activity against S. sclerotiorum and S. rolfsii. Foliar spray of bean and sunflower plants with AgNs caused a decrease in disease severity, which promoted the plant protection against S. sclerotiorum and S. rolfsii, respectively. Substantially, this study will extend our understanding of the AgNs antifungal action for suppressing fungal diseases.
Periodic Solutions and Stability Analysis for Two-Coupled-Oscillator Structure in Optics of Chiral Molecules
Authors: Li Jing , Chen Yuying , Zhu Shaotao
Published: June 2022

Chirality is an indispensable geometric property in the world that has become invariably interlocked with life. The main goal of this paper is to study the nonlinear dynamic behavior and periodic vibration characteristic of a two-coupled-oscillator model in the optics of chiral molecules. We systematically discuss the stability and local dynamic behavior of the system with two pairs of identical conjugate complex eigenvalues. In particular, the existence and number of periodic solutions are investigated by establishing the curvilinear coordinate and constructing a Poincaré map to improve the Melnikov function. Then, we verify the accuracy of the theoretical analysis by numerical simulations, and take a comprehensive look at the nonlinear response of multiple periodic motion under certain conditions. The results might be of important significance for the vibration control, safety stability and design optimization for chiral molecules.
An Efficient Orthogonal Polynomial Method for Auxetic Structure Analysis with Epistemic Uncertainties
Authors: Yin Shengwen , Qin Haogang , Gao Qiang
Published: June 2022

Traditional approaches used for analyzing the mechanical properties of auxetic structures are commonly based on deterministic techniques, where the effects of uncertainties are neglected. However, uncertainty is widely presented in auxetic structures, which may affect their mechanical properties greatly. The evidence theory has a strong ability to deal with uncertainties; thus, it is introduced for the modelling of epistemic uncertainties in auxetic structures. For the response analysis of a typical double-V negative Poisson’s ratio (NPR) structure with epistemic uncertainty, a new sequence-sampling-based arbitrary orthogonal polynomial (SS-AOP) expansion is proposed by introducing arbitrary orthogonal polynomial theory and the sequential sampling strategy. In SS-AOP, a sampling technique is developed to calculate the coefficient of AOP expansion. In particular, the candidate points for sampling are generated using the Gauss points associated with the optimal Gauss weight function for each evidence variable, and the sequential-sampling technique is introduced to select the sampling points from candidate points. By using the SS-AOP, the number of sampling points needed for establishing AOP expansion can be effectively reduced; thus, the efficiency of the AOP expansion method can be improved without sacrificing accuracy. The proposed SS-AOP is thoroughly investigated through comparison to the Gaussian quadrature-based AOP method, the Latin-hypercube-sampling-based AOP (LHS-AOP) method and the optimal Latin-hypercube-sampling-based AOP (OLHS-AOP) method.

Published: June 2022

Influenza and S. pneumoniae infections are a significant cause of morbidity and mortality worldwide. Intranasal live influenza vaccine (LAIV) may prevent influenza-related bacterial complications. The objectives of the study are to estimate resistance against early influenza infection and post-influenza pneumococcal pneumonia after LAIV in mice. Mice were administered intranasally the monovalent LAIV A/17/Mallard Netherlands/00/95(H7N3), A/17/South Africa/2013/01(H1N1)pdm09 or trivalent LAIV 2017–2018 years of formulation containing A/17/New York/15/5364(H1N1)pdm09 vaccine strain. LAIV demonstrated early protection against homologous and heterologous infections with A/South Africa/3626/2013 (H1N1) pdm09 influenza virus on day six, following immunization. Following boost immunization, trivalent LAIV demonstrated a pronounced protective effect both in terms of lethality and pneumococcal lung infection when S. pneumoniae infection was performed three days after the onset of influenza infection. Conclusion: LAIV provides early protection against homologous and heterologous viral infections and has a protective effect against post-influenza pneumococcal infection. These data suggest that the intranasal administration of LAIV may be useful during the cycle of circulation not only of influenza viruses, but also of other causative agents of acute respiratory infections.
Bifurcation Diagram and Dynamic Response of a Drill String Applied in NGH Drilling
Authors: Wang Baojin , Wang Liuci , Liu Xiaotong , Ren Fushen
Published: June 2022

Natural gas hydrate (NGH) is a kind of unique resource among hydrocarbon fuels. It is stable within its sedimentary hosts and will only convert to its constituent gas and water phases relatively quickly if reservoir pressure-temperature conditions are artificially disturbed. The unwanted vibrations from the drill string with the complex external environment and excitation usually cause instability in the NGH. In this paper, a nonlinear mathematical model is presented taking into account the fluid–solid coupling vibration caused by the drilling fluid inside and outside the drill string, the non-smooth rub-impact between the drill string and borehole wall, and the influence of centralizer setting interval on nonlinear resonant vibration of the drill string. The relationship between the variable parameters of the drill string and the complex dynamics of the drill string is analyzed. Finally, the bifurcation diagram is given. The results show that the system response exhibits complex dynamic behavior due to rub-impact and nonlinear effects. However, there is always a suitable parameter in the bifurcation diagram of each parameter change, so that the amplitude of the system is small and the failure probability of the drill string is reduced. The research results have reference significance for exploring the nonlinear dynamic mechanism of a drill string under complex working conditions and reasonably optimizing drilling parameters.
Wilderness Search for Lost Persons Using a Multimodal Aerial-Terrestrial Robot Team
Authors: Ku Shan Yu , Nejat Goldie , Benhabib Beno
Published: June 2022

Mobile robots that are capable of multiple modes of locomotion may have tangible advantages over unimodal robots in unstructured and non-homogeneous environments due to their ability to better adapt to local conditions. This paper specifically considers the use of a team of multimodal robots capable of switching between aerial and terrestrial modes of locomotion for wilderness search and rescue (WiSAR) scenarios. It presents a novel search planning method that coordinates the members of the robotic team to maximize the probability of locating a mobile target in the wilderness, potentially, last seen on an a priori known trail. It is assumed that the search area expands over time and, thus, an exhaustive search is not feasible. Earlier research on search planning methods for heterogeneous though unimodal search teams have exploited synergies between robots with different locomotive abilities through coordination and/or cooperation. Work on multimodal robots, on the other hand, has primarily focused on their mechanical design and low-level control. In contrast, our recent work, presented herein, has two major components: (i) target-motion prediction in the presence of a priori known trails in the wilderness, and (ii) probability-guided multimodal robot search-trajectory generation. For the former sub-problem, the novelty of our work lies in the formulation and use of 3D probability curves to capture target distributions under the influence of a priori known walking/hiking trails. For the latter, the novelty lies in the use of a tree structure to represent the decisions involved in multimodal probability-curve-guided search planning, which enables trajectory generation and mode selection to be optimized simultaneously, for example, via a Monte Carlo tree search technique. Extensive simulations, some of which are included herein, have shown that multimodal robotic search teams, coordinated via the trajectory planning method proposed in this paper, clearly outperform their unimodal counterparts in terms of search success rates.
Ensuring the Validity of the Results by Participating in ILC Schemes—Case Study: The Determination of the Water-Soluble Chromium (VI) Content of Cement
Authors: Stancu Cristina , Vijan Andreea
Published: June 2022

The paper presents the mode in which an accredited laboratory, according to SR EN ISO/IEC 17025, monitors its performance by comparing the results with the results of other laboratories. This article aims to analyse the results of the participation of an accredited laboratory in two ILC schemes, one organized in France and the other in Romania, on cement, discussing only the results of the determinations of the water-soluble hexavalent chromium content. Although chromium (VI) is not present in large amounts in cement, it is responsible for allergic reactions on the skin of workers. Thus, in EU countries, the maximum amount of water-soluble Cr (VI) in bagged cement or in the products based on cement is limited to a maximum of 0.0002% by mass of cement. The Chromium (VI) results obtained by the lab must meet the requirements of the standard SR EN 196-10 for the repeatability and, where appropriate, the reproducibility. Questions about the validity of the results arise when the laboratory obtains satisfactory results in the ILC scheme, but the standard deviation of the scheme is higher than that recommended in the standard method. The elements of the novelty of this paper are the interpretation of water-soluble Cr (VI) results and the use of information obtained from participating in interlaboratory testing schemes tom improve the validity of laboratory results.
Formulation of Radiometric Calibration for Azimuthal Multi-Angle Observation Space-Borne SAR
Authors: Huang Jianjun , Chen Jie , Guo Yanan , Wang Pengbo
Published: June 2022

A novel space-borne SAR technique, azimuthal multi-angle observation (AMAO), has recently been proposed. It has highly flexible working modes and powerful capability of target information acquisition, but has challenges in achieving radiometric measurement accuracy. The larger the squint angle, the higher the resolution and the more variations involved. Radiometric calibration is a necessary approach to consistent and accurate SAR measurements, but has so far not been carefully considered for AMAO space-borne SAR. This paper addressed the new issues in radiometric calibration arising from the AMAO space-borne SAR system. The AMAO imaging modes are firstly been illustrated, based on which the influences of the AMAO on radiometric calibration are analyzed. To guarantee the accuracy of the radiometric calibration, an appropriate form of the SAR radar equation is derived for AMAO space-borne SAR. On these bases, the calibration models can be obtained by reformulating the novel AMAO SAR equation, and the corresponding normalization method is then proposed. The good experimental performance indicators verify the correctness of proposed models and the effectiveness of the correction method.

Published: June 2022

Nocardiosis, a rare infectious disease in dogs and cats, is caused by Gram-positive aerobic actinomycetes of the genus Nocardia. A one-year-old castrated male Great Dane was presented with clinical signs of an ulcerated nodule on the right ear, which was observed after two weeks of treatment with cyclosporine and prednisolone due to idiopathic hepatitis. Cytological examination revealed pyogranulomatous inflammatory cells and blanched filamentous rods. To detect infectious agents, serosanguinous discharge of the nodule was subjected to bacterial and fungal cultures. For phenotyping of the infectious agents, colonies on blood agar culture plates were further analyzed by matrix-assisted laser desorption ionization (MALDI)-time-of-flight (TOF) mass spectrometry (VITEK MS). The MALDI-TOF spectra were identified as N. africana. Thus, the present case was diagnosed as cutaneous nocardiosis. The skin lesions of ulcerated nodules with fistulous tracts were gradually resolved by the administration of meropenem (8 mg/kg TID, IV) and doxycycline (5 mg/kg BID, PO). Although complete resolution of the skin lesions was observed on day 91 after the initial presentation, single administration of doxycycline was continued until day 198 after the initial presentation to prevent recurrence. To the best of our knowledge, this is the first report of Nocardia africana infection in a dog. In addition, our results show that MALDI-TOF mass spectrometry analysis could be a useful tool for the detection of Nocardia. spps.

Published: June 2022

This study aims to assess the main causes of proteinuria in dogs from the region of Lisbon (Portugal), estimating the relevance of screening for canine vector-borne diseases (CVBDs). A cross-sectional retrospective study was conducted. Medical records from proteinuric dogs (urinary protein–creatinine ratio > 0.5) presented to a Veterinary Teaching Hospital over a two-year period were reviewed for signalment, established diagnosis, proteinuria origin, and CVBD screening results. A total of 106 dogs were included. The median age was 9.5 years old (IQR: 7–12). Proteinuria was considered of renal origin in 76% of cases (46% of them had a presumptive diagnosis of glomerulonephritis secondary to CVBD, 27% chronic kidney disease, 26% systemic disease possible to induce proteinuria, and 1% leptospirosis). Proteinuria was classified as post-renal or mixed-origin in 17% and 7% of cases, respectively. About 35% of proteinuric dogs were positive for at least one CVBD. Of them, 84% were seropositive for one CVBD, while 16% tested positive for two or more. Among dogs testing positive for CVBD, 89% were seropositive for Leishmania infantum. This study showed that about one-third of proteinuric dogs tested positive for CVBDs, highlighting the relevance of their screening in dogs with proteinuria living in endemic regions.

Published: June 2022

A 3-year-old male Slovak Hound with retinal detachment was presented. The causative intraocular mass was detected by ultrasonography, and the course of the disease was monitored over a 3-year period. Enucleation was performed due to secondary glaucoma. A benign choroidal melanocytoma was diagnosed by histopathology. To our knowledge, this is the first report that describes the disease over such a long period of time. The mild course of the disease questions enucleation of eyes with no or minor symptoms. Conventional treatment may be a suitable alternative to surgery for dogs with high anesthesia risks.
April 25 — World Malaria Day
Authors:   SBHI RR Kerch City Children's Hospital, Rybachok Oksana Aleksandrovna
Published: June 2022

Since 2008, the world community has been celebrating World Malaria Day on April 25, while in Africa this date has become memorable since April 2001. After a country registers no new disease cases for three consecutive years, the country moves into the category of states that have beaten malaria. For instance, in the 21st century, the UAE, Maldives, Kyrgyzstan, Armenia, Turkmenistan, Morocco and Sri Lanka were classified as such countries. Europe was declared 100 % malaria free in 2016. However, despite the successes achieved in the fight against malaria, the world has not been able to completely defeat this disease, and it continues to affect people in Africa, Southeast Asia and South America, with up to a quarter of a billion cases of the disease recorded annually. In 2019 alone, more than 400,000 people became victims of malaria, of which two-thirds were young children under the age of five. In Russia, about 100 cases of the disease are recorded annually, all of them are imported from abroad. An important factor in successful therapy is the need for the earliest possible start of etiotropic treatment. One of the leading problems in the treatment of tropical malaria is the emergence of resistance to many drugs. The malaria causative agents are malaria Plasmodia, and its carriers are mosquitoes of the genus Anopheles. The classic clinical manifestations of malaria include fever, hepato- and splenomegaly, anemia; this disease is characterized by a relapsing course. It is believed that Tutankhamun died from malaria, as well as the famous Portuguese navigator Vasco da Gama.
Difference in the perceived loudness of sound between Chinese men and women

Published: June 2022

Gender differences in perceived loudness have been observed between Japanese men and women in previous studies. Female participants tended to assign higher loudness scores to sounds of the same sound pressure level than did male participants. However, this difference was not clearly
observed when using a ratio scale for the evaluation of loudness, such as in a magnitude estimation. To discuss factors affecting gender differences in perceived loudness, the same rating experiments used in previous studies were conducted with Chinese men and women. A rating experiment using
a verbal interval scale showed that Chinese women tended to rate the same sounds as louder than did Chinese men. The gender effect was replicated in an experiment using an adjustment method that measured the limits of the sound pressure level perceived as soft or loud; women selected lower
levels than did men for the highest limit of soft sounds and the lowest limit of loud sounds. These tendencies were the same as those of Japanese men and women observed in previous studies. Rating experiments adopting the methods of magnitude estimation and magnitude production for the ratio
scales showed that the power exponent a in Stevens' power law was larger for female participants than for male participants under some conditions. However, the observed gender difference in the power exponent a for Chinese was not consistent, while it was not clear for Japanese. The gender
difference in criteria for verbally categorizing loudness may be responsible for the gender difference in perceived loudness.

O tratamento ER ocorre a partir de uma fonte de alimentação externa com um dos polos ligados ao aço (cátodo) e outro ligado a uma malha metálica auxiliar (ânodo), normalmente de titânio ou aço galvanizado, a estrutura deve estar embebida em um eletrólito, sendo comum a utilização da solução de carbonato de sódio. O tratamento visa restabelecer a alcalinidade do concreto em torno das armaduras e em toda a cobertura de concreto. Desta forma, o presente estudo visa abordar uma revisão da bibliografia, compilando diversos estudos sobre realcalinização eletroquímica de estruturas de concreto armado carbonatadas.

Discutir acerca das principais repercussões da COVID-19 na função respiratória de pacientes pediátricos e neonatos. Revisão eletrônica das bases de dados LILACS, PubMed, e SciELO utilizando os descritores “COVID-19”, “repercussions” “pediatric”. A pesquisa foi realizada no período de  Novembro de 2021 à Janeiro de 2022, tendo como critérios de inclusão publicações entre os anos de 2010 à 2021, nos idiomas Português, Inglês e Espanhol, com relatos acerca das repercussões da COVID-19 na função respiratória pediátrica e neonatal e critérios de exclusão, artigos de revisão, estudos realizados em animais, artigos pagos, estudos publicados em ano inferior a 2010 e artigos duplicados nas bases de dados. Foram encontrados 40 estudos, destes 11 artigos preencheram os critérios de inclusão. A maioria dos casos observados na pediatria são assintomáticos, no entanto, os poucos casos sintomáticos, apresentam manifestações clínicas, como: tosse seca, coriza, odinofagia, secreção nasal e febre; e nos casos de pacientes graves, sintomas como: febre alta, SDRA, fadiga/mialgia e polipneia, podendo haver riscos de Pneumonia e SIM-P. Apesar das repercussões, pacientes pediátricos e neonatais demonstram um bom prognóstico, quando tratados de maneira individualizada. Por isso, entender e discorrer acerca das principais manifestações que acometem este público é de suma importância para a evolução do tratamento precoce contra às sequelas da COVID-19.

Background: Emphysematous cystitis is a disease of the bladder with retention of gas in the bladder wall or lumen. The risk factors include urinary tract infection by gas producing anaerobic bacteria and fungi, diabetes mellitus and compromised immunity. Primary risk factor being diabetes mellitus, emphysematous cystitis can occur with unsual presentations like hypervolemic shock. Imaging technologies are widely used to diagnose and detect emphysematous cystitis. However, better diagnosis can be achieved by computed tomography (CT) of the abdomen and pelvis. Early and accurate diagnosis of  emphysematous cystitis in diabetic patients can result in better prognosis of the disease.Case presentation: Here, we report for the first time a case of emphysematous cystitis with hypovolemic shock with type 2 diabetes mellitus, and present a review of literature on the topic. The diabetic patients with emphysematous cystitis should be cautiously monitored for hypervolemic shock along with the routine management of the disease. Conclusions: Such patients should be kept on constant monitoring for hypervolemic shock along with conventional diagnosis and management of the disease.

Os fungos endofíticos são reconhecidos por sua imensa capacidade de produção de metabólitos que atuam como antimicrobianos, além de serem produtores de diversas enzimas extracelulares. Assim, o objetivo deste trabalho foi avaliar a atividade antibacteriana e enzimática de fungos endofíticos da coleção de microrganismos do IFMT - Campus Avançado de Lucas do Rio Verde. Ao todo foram testadas doze linhagens de fungos endofíticos, isolados da raiz de Cyperus rotundus (tiririca) e da folha de Zea mays (milho). Para o teste de atividade antibacteriana, utilizou-se o método de difusão em ágar e a determinação da concentração inibitória mínima (CIM) contra bactérias patogênicas gram-positivas: Staphylococcus aureus 25923, Listeria monocytogenes; e gram-negativas: Escherichia coli 25922, Salmonella choleraesuis 10708, Helicobacter pylori 43504, Shigella flexneri 12022. Utilizou-se as seguintes linhagens de fungos: Lasiosphaeriaceae sp R2B, Lasiosphaeriaceae sp R8E, Talaromyces pinophilus FEFM I, Ceriporia alachuana R9C, Fusarium acutatum T9E, F. acutatum R7C, F. acutatumR5A, Trichoderma sp. R4A, Fusarium oxysporum T2A, F. oxysporum T7C e Fusarium solani T1A e uma linhagem não identificada R9B. Para o  primeiro ensaio, discos miceliais (±7mm) foram retirados e situados em placas com meio Mueller-Hinton inoculado com  bactéria patogênica padronizada a 0,5 da escala de McFarland. As placas foram incubadas a 37°C por 24 h e a atividade foi determinada de acordo com a formação de halos de inibição. A determinação da CIM foi realizada a partir dos extratos fúngicos liofilizados nas concentrações de 0,16 a 20,00 mg/mL em microplacas de 96 poços, incubados a 37°C por 24 h, lidas em espectrofotômetro a 450 nm e reveladas com resazurina. A atividade enzimática foi determinada para as enzimas amilase e protease mediante a formação de halos de degradação de seus respectivos meios. Na avaliação da atividade antibacteriana pelo teste de difusão em ágar, dez isolados (FEFM I, R9C, T9E, R4A, R7C, R9B, T2A, R5A, T1A, T7C) apresentaram atividade contra Helicobacter pylori e oito (R2B, R9C, T9E, R7C, R9B, T2A, R5A, T1A) contra Shigella flexneri, com destaque para o fungo R9C que apresentou atividade contra quatro cepas de bactérias patogênicas utilizadas: Salmonella choleraesuis, Helicobacter pylori, Shigella flexneri e Listeria monocytogenes. Nenhuma concentração dos extratos liofilizados testados inibiram o crescimento das cepas patogênicas. Quanto à atividade enzimática, quatro isolados apresentaram atividade positiva e quatro fortemente positiva para amilase, sete isolados com atividade fortemente positiva e três positivos para atividade proteolítica. Entre os gêneros de fungos utilizados, Fusarium foi o que apresentou maior potencial biotecnológico, já que apresentou atividade antibacteriana e enzimática promissoras.

A Pokkah boeng é uma doença causada por Fusarium sacchari que, embora ainda emergente, tem despertado atenção devido a sintomatologia observada em diversas regiões canavieiras do Brasil. Este estudo teve como objetivo avaliar a resistência de genótipos de cana-de-açúcar à F. sacchari nas condições ambientais de temperatura e umidade relativa preponderantes na região canavieira do estado do Piauí, Brasil. Inicialmente foi conduzido um ensaio no período chuvoso da região usando 16 clones de cana-de-açúcar que foram inoculados com F. sacchari via suspensão de esporos. Os níveis de resistência foram estabelecidos por scores (de 0-5) de uma escala diagramática e posterior classificação mediante o índice de severidade da doença (ISD). Posteriormente, quatro clones de cana-de-açúcar com os menores e quatro com os maiores ISD selecionados previamente no primeiro ensaio foram submetidos a um novo ensaio durante o período seco da região, utilizando-se a mesma metodologia do primeiro ensaio. Ficou demonstrado que a agressividade do fungo se torna mais expressiva em alguns genótipos, em geral, quando as médias de temperaturas estão em torno de 34 0C e umidade relativa do ar em torno de 75%. Assim, no período seco do ano, correspondente ao período de junho a novembro, a incidência desta doença é praticamente nula mesmo para os genótipos mais suscetíveis. Assim, nossos resultados demonstram que, apesar de haver inóculo do patógeno presente na região, o desenvolvimento de F. Sacchari não causa danos significativos à cana-de-açúcar em virtude das condições ambientais que limitam à doença.

A endofibrose arterial é uma doença vascular que caracteriza-se pelo espessamento arterial com acometimento das artérias ilíaca externa, femoral comum e poplítea. A população de risco inclui os ciclistas e triatletas. Seu quadro clínico inclui dor e claudicação intermitente de membros inferiores durante a prática de atividade esportiva de alta intensidade, devido a diminuição do fluxo sanguíneo ocasionada pela redução do lúmen arterial. O quadro clínico, atípico em pacientes jovens, associa-se à confusão diagnóstica com lesões musculoesquelética e resulta em diagnóstico, tratamento e reabilitação tardios. A avaliação da circulação periférica através da palpação de pulsos e da realização do índice de pressão tornozelo braquial auxiliam o seu diagnóstico, porém, para um diagnóstico preciso desta doença é necessário realizar um Ultrassom Doppler arterial das artérias ilíacas e das artérias dos membros inferiores. O Ultrassom Doppler é um exame não invasivo, pouco oneroso, operador dependente e não exige a administração intravenosa de contraste. O tratamento da endofibrose arterial é cirúrgico.
