Published: July 2024

Novel aircraft configuration, such as drones, have emerged during the last decades. This project aims to offer insights into drone development, enhancing its efficiency by means of rotor optimization utilizing well-established theoretical models based on blade element momentum theory for estimating thrust generation and power requirements at hover and forward flight. The impact on performance of chord and airfoils pitch angle, particularly focusing on the twist, which is how pitch changes along the blade, is analyzed, followed by optimizations of multiple chord and twist distributions at different flight conditions. Additionally, Computational fluid dynamics tools are employed to simulate resulting rotor geometries and to the baseline. Simulations and model predict power reductions of 3% to 17%, with negative twist rates and increased platform as main characteristics of most efficient geometries.

Published: July 2024

Objectives: To evaluate prevalence and predictors of eclampsia in patients with preeclampsia. Material and Methods: database of 11,026 consecutive births attended between Nov-98 and Jun-04, 323 patients admitted with a diagnosis of preeclampsia (blood pressure >=140-90 in 2 doses plus proteinuria) were included in this retrospective analysis. Eclampsia was diagnosed in the presence of associated seizures. Multiple logistic regression analysis was performed to identify independent markers of eclampsia. Results: The diagnosis of eclampsia was established in 32 (10%) patients. Patients with and without eclampsia differed in the following characteristics: primiparous (14.7 vs 6.4%, p=0.014), chronic anemia (14.6 vs 7.2%, p=0.031), adolescence (≤ 16 years) (40 vs 8.4%, p =0.002), smoking (29.2 vs 8.4%, p=0.005), multiple pregnancy (47.1 vs 8%, p<0.0001) and obesity (2.1 vs 11.8%, p=0.026). In the multivariate analysis, the independent predictors were the followings: multiple pregnancy (OR=13.6, 95%CI=4.4-41.8, p<0.0001), smoking (OR=4.9, 95%CI=1.6-15.1, p=0.006) and adolescence (OR =17.9, 95%CI=4.7-67.7, p<0.0001). In patients with none, one or two, and three variables, eclampsia occurred in 0% (0 of 265 cases), 44.7% (24 of 47), and 100% (11 of 11), respectively (p<0.0001). Conclusions: One in 10 patients with preeclampsia developed eclampsia during hospitalization. Three simple and widely available variables (adolescent mothers, smokers, and twin pregnancy) were useful to identify low- and high-risk population.

Published: July 2024

Systemic lupus erythematosus (SLE) is an autoimmune, chronic, and heterogeneous disease. Antimalarial drugs, such as hydroxychloroquine (HCQ) is still an important immunomodulator medicine for the treatment of SLE. Rarely, HCQ toxicity can occur. We report a case of a patient who was admitted to our hospital with clinical symptoms of heart failure with a background of history of SLE and chronic HCQ use. Dilated cardiomyopathy in parallel with increased left ventricular apical trabeculation consistent with left ventricle non-compaction cardiomyopathy (LVNC) was diagnosed. We aim to pinpoint two rare manifestations presenting in the same patient, simultaneously a) the reversible dilated cardiomyopathy after modification of the dose of HCQ and b) the non-reversible left ventricle non compaction cardiomyopathy most likely associated with her underlying disease. HCQ cardiomyopathy is rare but occasionally correlated with undesirable side effects. It is crucial to consider it in any patient taking for prolonged time the medication, who presents with symptoms of heart failure.

Background: Maternal-fetal bacterial infection remains a concern for pediatricians due to diagnostic and therapeutic difficulties and increased morbidity and mortality. The objective of this work was to describe the epidemiological, clinical and bacteriological profile of maternal-fetal infection in Libreville and Lambaréné. Methods: This is a prospective and descriptive study carried out in 2 university hospitals in Libreville and the regional hospital of Lambaréné. We included newborns with at least one criterion from the National Agency for Accreditation and Evaluation in Health ANAES. Results: we collected 53 newborns. The ANAES criteria were time to rupture > 18 hours (17%), prematurity ˂37SA and ≥35SA (24.5%), maternal perinatal fever (18.7%), and abnormal amniotic fluid (66%). Newborns were symptomatic (35.9%). Symptoms were dominated by respiratory signs (30.2%). On biology, anemia and thrombocytopenia accounted for 22.6% and 20.8% respectively. The bacterial ecology was dominated by Gram+ cocci (66.7%) consisting of coagulase negative Staphylococci (Staphylococcus lentus = 29.2%). Sensitive antibiotics were vancomycin and ofloxacin. For Gram Negative Bacilli (E. coli = 41.7%), the sensitive antibiotics were amikacin and imipenem. Conclusion: The infectious risk criteria of the ANAES remain relevant in our practice. The bacterial ecology is different from that known with a high sensitivity to unusual antibiotics. Optimization of these antibiotics would reduce morbidity and mortality linked to maternal-fetal infection.

Published: July 2024

Due to the high rates of obesity in Iran, this study aimed to investigate the relationship between density, accessibility to public transport and green spaces, obesity, and related diseases in Babol. Data were collected from 1200 participants, and logistic regression was employed to analyse health indicators such as body mass index (BMI), blood pressure, and diabetes, alongside environmental indicators including population density, residential density, accessibility to bus and taxi stations, the number of stations, and green space area. The study found that living in areas with a density of over 120 people per square kilometre reduces the likelihood of being overweight or obese compared with areas with a density of 100 to 120 people. Access to green spaces within a 200-metre radius did not show a significant association with diseases. There was a weak negative relationship between the number of public transportation stations at different distances and BMI, indicating lower levels of overweight and obesity. Changing from neighbourhoods with lower residential densities to higher residential densities reduced the likelihood of developing heart disease and diabetes by about 74% and 44.4%, respectively. The presence of green spaces in neighbourhoods had a weak correlation with the reduction of obesity and related diseases. Increasing the number of taxi and bus stations from one to three within a 400-metre radius significantly reduced the likelihood of developing high blood pressure by approximately 70% and diabetes by 56.5% within a 200-metre radius. Living within a distance of less than 150 metres from the nearest public transportation station or nodal points was associated with a 51.3% lower probability of developing high blood pressure compared with living within a distance of 300 to 500 metres from public transportation stations. Based on the findings, the paper presents possible implications for policy and practice.

Abstract :Classic feature of any research analytics system is to be able to provide a metric based on the given research data given like the citation count and other kinds of data it is important to analyze the given data and give feedback and understand performance of a given research department, Scholar or the research, So we used a novel approach to rate given person based on the research work and comparing it with different works published in the same area, it is to be noted that the score/rating only focuses on the domain rather than rating the whole scholars work this way we can estimate the scholar's performance with respect to one domain which several other types of ratings fail to do so. This method will act advantageously especially in research organizations where appraisals and giving research grants are usually done based on scholar's previous work in a specific domain. We were able to formulate results for 62 different authors from 8 different domains, these domains and authors were picked randomly so as to efficiently understand the working of the methodology we followed four essential steps in this approach namely gathering dataset, applying Glicko- 2 ranking algorithm, finding average rating value for all works finally calculating d-impact score using GPA method on the scale of 9. We can conclude that the result is a both domain-specific and more accurate representation of the author's impact. In work we gave introduction regarding methodology and description of existing technologies in section 1, In section-2 we described the need of the proposed methodology with few sample results in existing methodology and proposed one, In section-4 we described the methodology in step by step manner and also presented proposed algorithm with all the required formulae, In section-5 we presented analysis and actual summary of the results, In section-6 we presented the conclusion.

Abstract: In the realm of higher education, efficient and user-friendly tools for result analysis play a pivotal role in evaluating the academic performance of university graduates. A systematic processing of the examination results and their meaningful representation requires enormous labor when attempted manually. The students are generally unaware of the computational metrics of semester grade point average (SGPA) and cumulative grade point average (CGPA) though they like to get updated on their performance periodically. In this study, a straightforward computer code is developed in C++ language to enable the students to calculate their academic progress (in terms of SGPA and CGPA) using the input data of marks and credits of individual subjects. The code is designed with simplicity and practicality in mind, to enable the students, parents, teachers and administrators with a versatile tool for comprehensively assessing the academic outcomes. The validity of the software program is verified by comparing the computational performance for three Indian universities, namely, Anna University, N. Natarajan Department of Civil Engineering, Dr, Mahalingam College of Engineering and Technology, Pollachi - 642003, Coimbatore District, Tamil Nadu, India. itsrajan2002@yahoo.co.in University of Madras and Indraprastha University in estimating the SGPA and CGPA on a 10-point scale. The results suggest that the code provides an accurate and time-saving solution compared to manual calculation. The results demonstrate the code's ability to verify the grades by the students as well as their mentors to keep track of the performance. This user- friendly tool will be highly beneficial for streamlining the result analysis process, providing valuable insights for the academicians towards decision- making and strategic planning.

Abstract: Educational infrastructure is moving towards rapid digitization to conduct and evaluate examinations for remote students. Many universities now offer globally recognized distance learning courses to cater to a wider audience. However, this transition comes with its set of challenges, particularly for professors and staff members who find themselves burdened with a substantial amount of manual work during the examination season. The tasks include setting up unique question papers for every exam, including different types of questions with varying difficulty, and eventually evaluating the answers given by the students, which is not only timeconsuming but also a labour-intensive process. To address this issue, the paper proposes a solution that aims to reduce the workload of teaching staff by enhancing the efficiency of the examination process. It does so by leveraging several natural language processing techniques for generating two types of questions- objective and subjective, and grading the solutions of the examinee. Additionally, subjective questions are further classified based on Bloom's taxonomy levels, providing a diverse range of questions that align with varying cognitive abilities. The automation of this process not only eases the burden on educators but also ensures a more streamlined and effective examination process, thus contributing to the broader goal of digitizing education. Keywords: Automated Question Generation, Bloom's Taxonomy, Workload Reduction.
Determination of the efficacy of some entomopathogenic nematodes on Spodoptera littoralis (Boisduval, 1833) (Lepidoptera: Noctuidae) in laboratory conditions
Authors: Partal Esra , Kaşkavalcı Galip
Published: July 2024

Spodoptera littoralis (Boisduval, 1833) (Lepidoptera: Noctuidae) is a polyfag pest causing losses all over the world. Entomopathogenic nematodes (EPN) have a regulatory role on insect populations in the soil ecosystem. The aim of this study was to determine the effects of commercial biopreparations of some EPNs on fifth instar larvae of S. littoralis at different doses and days. Biopreparations containing Heterorhabditis bacteriophora (Poinar, 1975) (Rhabditida: Heterorhabditidae), Steinernema carpocapsae (Weiser, 1955) and Steinernema feltiae (Filipjev, 1934) (Rhabditida: Steinernematidae) were used in the study. These biopreparations were adjusted at doses of 50, 100, 200 and 400 IJs/5ml of tap water and applied to 50 g of sterilized sandy soil in a plastic container, and one individual of S. littoralis larvae was released on it. The study was conducted in 2022 at 27±2°C under laboratory conditions for 5 days. According to the results of the study, the highest average mortality rates were 100 and 95% in the S. carpocapsae preparation application at 400 and 200 IJs doses on the 5th day, respectively. In the application of S. feltiae preparation, 90% mortality rate on average was observed at 200 and 400 IJs doses on the 5th day. Heterorhabditis bacteriophora preparation treatment showed the highest mean mortality rate of 75% at 400 IJs dose and on the 5th day. This study is an acceptable step in determining the possibilities of using EPNs in the control of S. littoralis.

Published: July 2024

It has been reported that long non-coding RNAs (lncRNAs) are involved in sepsis-induced liver injury, while the role of cancer susceptibility candidate 7 (CASC7) in liver injury induced by sepsis remains elusive. In our study, 62 patients and 55 healthy controls were enrolled from our hospital, from whom CASC7 and microRNA-217 (miR-217) in serum samples were detected by quantitative real-time PCR (qRT-PCR). Then the sepsis-induced liver injury mice model was established by lipopolysaccharide (LPS). The effect of CASC7 on liver injury induced by sepsis was confirmed by hematoxylin and eosin (HE) staining, ELISA assay, TUNEL assay, Annexin V-FITC apoptosis assay and cell counting kit-8 (CCK-8) assay, respectively. Besides, RNA pull-down, luciferase reporter gene assay, qRT-PCR, and western blot were used to evaluate the underlying mechanisms. In this study, lncRNA CASC7 was significantly increased while miR-217 was significantly decreased in patients with sepsis-induced liver injury compared with that in healthy controls. There was a negative association of CASC7 and miR-217 in serum samples from patients with sepsis-induced liver injury and healthy controls. CASC7 was upregulated in a time-dependent manner in liver tissues of LPS-treated mice. It was found that knockdown of CASC7 reduced the liver injury induced by LPS in mice. In vitro, LPS treatment enhanced cell apoptosis, while knockdown of CASC7 inhibited the role of LPS in cell apoptosis. Moreover, knockdown of CASC7 suppressed the LPS-enhanced tumor necrosis factor alpha (TNF-α) and interleukin 1 beta (IL-1β) expression. In addition, miR-217 was found to be a target of CASC7, and miR-217 mimic could reverse CASC7-promoted liver injury. Furthermore, toll-like receptor 4 (TLR4) was identified as the target of miR-217, and both CASC7 and miR-217 could downregulate the mRNA and protein level of TLR4. Additionally, TLR4 overexpression could reverse miR-217-inhibited or CASC7-promoted liver injury. Taken together, CASC7 contributes to the progression of LPS-induced liver injury via the miR-217/TLR4 axis.

Published: July 2024

The importance of evaluating the nutritional status and immune condition prior to surgery has gained significant attention in predicting the prognosis of cancer patients in recent years. The objective of this study is to establish a risk model for predicting the prognosis of gallbladder carcinoma (GBC) patients. Data from GBC patients who underwent radical resection at West China Hospital of Sichuan University (China) from 2014 to 2021 were retrospectively collected. A novel risk model was created by incorporating the prognostic nutritional index and glucose-to-lymphocyte ratio, and each patient was assigned a risk score. The patients were then divided into low- and high-risk cohorts, and comparisons were made between the two groups in terms of clinicopathological features and prognosis. Propensity score matching was conducted to reduce potential bias. A total of 300 GBC patients receiving radical surgery were identified and included in this study. Patients in the high-risk group were older, had higher levels of serum carcinoembryonic antigen (CEA), cancer antigen 125 (CA125), and cancer antigen 19-9 (CA19-9), were more likely to experience postoperative complications, and had more aggressive tumor characteristics, such as poor differentiation, lymph node metastasis, and advanced tumor stage. They also had lower overall survival (OS) rates (5-year OS rate: 11.2% vs. 37.4%) and disease-free survival (DFS) rates (5-year DFS rate: 5.1% vs. 18.2%). After propensity score matching, the high-risk population still experienced poorer prognosis (5-year OS rate: 12.7% vs 20.5%; 5-year DFS rate: 3.2% vs 8.2%). The risk model combining prognostic nutritional index and glucose-to-lymphocyte ratio can serve as a standalone predictor for the prognosis and assist in optimizing the treatment approach for GBC patients.

В статье рассматривается проактивное управление жизненной энергией и события на работе как «спусковой крючок» такого проведения. Согласно теории аффективных событий (affective events theory) события рабочей жизни влияют на аффективные реакции сотрудников в качестве экзогенных факторов. Цель. Цель исследования — выявить характер взаимосвязи рабочих событий и проактивного поведения работников. Дизайн исследования. В исследовании приняли участие 58 руководителей (23 женщины, 35 мужчин, руководители продуктовых направлений в сфере информационных технологий), которые в течение 50 дней (восьми недель) регистрировали свою проактивность с помощью методики «Факторы проактивного управления жизненной энергией» (proactive vitality management factors) и рабочие события, заполняя авторскую анкету. Всего произведено 1028 замеров (с учётом пропущенных). Результаты. Выделено два компонента проактивного управления жизненной энергией — готовность к работе и самомотивация. Определены тенденции к изменению готовности к работе и самомотивации, взаимосвязанной с рабочими событиями. Обнаружен цикличный характер изменений (колебаний) готовности к работе в командной работе (короткий цикл из шести рабочих дней). Выводы. Работоспособность сотрудников поддерживается после произошедшего события двумя различными способами. События имеют как мгновенный эффект (аффективную реакцию) — влияют на готовность к работе сотрудников, так и отсроченный — увеличивают их самомотивацию в последующие дни. Готовность к работе зависит от события, происходящего «здесь и сейчас», а последействие события отсутствует, то есть на следующий день уровень готовности к работе возвращается к исходному уровню. В случае с самомотивацией, наоборот, больший эффект оказывает насыщенность последних дней важными событиями — чем больше таких событий происходит, тем быстрее растёт самомотивация.

O aumento da resistência bacteriana tem levado a busca pela descoberta de novos antibióticos e a potencialização de classes de antibióticos já existentes. A síntese verde ganha espaço nessa área por utilizar componentes orgânicos que reduz o custo do processo e produz uma abordagem menos danosa ao meio ambiente. A pesquisa objetivou comparar as diferentes sínteses de nanopartículas de prata e avaliar a atividade antimicrobiana. Foram utilizadas sete amostras vegetais de espécies encontradas na Amazônia: Cassimirela (Humirianthera ampla), Copaíba (Copaifera officinalis L), Sacaca (Croton cajucara BENTH), Maclura (Maclura tinctoria), Quina-quina (Cinchona officinalis) e Pimenta Longa (Piper longum). A extração do óleo essencial das plantas se deu através da técnica de arraste a vapor. A síntese de nanopartículas ocorreu através da rota verde utilizando extratos de plantas como agente redutor (Nps Ag orgânica) e borohidreto como agente redutor na síntese química (Nps Ag Inorganica). Para caracterização das nanopartículas sintetizadas foram realizadas análises espectroscópicas de UV-Vis seguido da análise por espalhamento dinâmico de Luz (DLS). Os diferentes extratos analisados no ensaio não demonstraram ter ação antimicrobiana nas diferentes cepas utilizadas, porém as nanopartículas sintetizadas a partir da utilização do extrato como agente redutor obteve resultado em três sínteses copaíba, cassimirela e sacaca.

O objetivo desse estudo foi avaliar as condições higiênico-sanitárias de estabelecimentos que produzem e comercializam maionese correlacionando com a qualidade microbiológica das maioneses caseiras. Os estabelecimentos foram analisados através de um Guia de Conformidades baseado na RDC n°275/2002 e RDC Nº 216/2004 e análise microbiológica da maionese a partir das contagens de Staphylococcus aureus, coliformes totais e termo tolerantes e presença/ausência de Salmonella spp. Todos os estabelecimentos apresentaram baixa conformidade de atendimento a legislação brasileira, sendo que apenas um estabelecimento atendeu a mais de 50% dos requisitos. Em todas as amostras de maionese constatou-se presença de coliformes totais, e em 83% das amostras foram detectados coliformes termo tolerantes. Em nenhuma das amostras foi encontrado a presença de Salmonella spp. e em apenas 29% das amostras foram identificados valores de S. aureus acima de 100 UFC.g-1. Análises multivariadas apontam para uma forte relação (p < 0,05) entre altos números de micro-organismos indicadores de higiene (i.e., coliformes totais e termo tolerantes) nas maioneses caseiras ao baixo percentual de conformidades nos estabelecimentos comerciais. De forma contrária, a contagem de S. aureus e a presença de Salmonella spp., nas amostras de maionese, não são bons indicadores no atendimento de requisitos apontados pela legislação brasileira vigente.

O presente estudo objetivou verificar a ação antagônica de leite fermentado de kefir e cultura lática mesofílica frente a patógenos em queijo Minas frescal. O Kefir foi obtido e fermentado em leite UHT para obtenção do leite fermentado de Kefir. O queijo Minas Frescal foi elaborado com os mesmos ingredientes e nas mesmas condições variando somente o fermento utilizado, 1% de leite fermentado de Kefir e 1% de cultura lática mesofílica (5% de L. lactis e 95% de L. cremoris). Foram adicionados às formulações de queijos Eschericia coli e Staphylococcus aureus separadamente, além do queijo controle, sem adição de patógenos. Os produtos foram avaliados quanto à contagem de bactérias láticas, E. coli e S. aureus, nos tempos 0,7,14 e 21 dias de fabricação. A contagem de bactérias láticas foi de 7 log UFC.g-1 para as formulações controle e para as formulações adicionadas de E. coli e S. aureus variou de 6 a 7 log UFC.g-1. Em relação à contagem de E. coli foi observado que o Kefir teve capacidade de reduzir 1,58 ciclos log, enquanto a cultura lática 0,27. Em relação à redução de S. aureus não houve diferença (p>0,05), entre as formulações e tempo. Ainda com adição de patógenos as bactérias láticas apresentaram contagem superior a 6 log UFC.g-1. O Kefir demonstrou reduzir a contagem de Escherichia coli, evidenciando seu possível uso como cultura biocontrole.

É crescente a busca dos consumidores por produtos de panificação mais saudáveis, ricos em fibras e ingredientes naturais e, com isso, a indústria investe em produtos para atender essa demanda. Buscou-se nesse estudo avaliar o perfil e a percepção de consumidores sobre pães, probióticos e ora-pro-nobis, além da intenção de compra de pães com farinha de ora-pro-nobis e bactéria probiótica por meio de questionário on-line, contendo 27 questões. Foram obtidas 327 respostas de participantes de ambos os sexos, maiores de 18 anos. Constatou-se que 99% dos potenciais consumidores se interessam por produtos saudáveis. As mulheres, em detrimento aos homens, buscam produtos de panificação diferenciados e adicionados de ingredientes naturais e funcionais. Mulheres entre 18 e 34 anos se mostraram mais interessadas em produtos que confiram saúde, controle de peso e ingredientes naturais, enquanto mulheres com mais de 35 anos se preocuparam mais com preço e apelo sensorial. A nuvem de palavras evidenciou que a doença cardiovascular mais comum entre os participantes foi hipertensão. O público masculino é maior consumidor de pão francês (53,9%), diferente das mulheres. Os quesitos saúde, conteúdo natural e perda de peso foram os mais decisivos para os consumidores, especialmente para as mulheres, na escolha do produto. Os pães adicionados de farinha de ora-pro-nobis e bactéria probiótica vão ao encontro das principais tendências de consumo do público que busca alimentos de maior funcionalidade. O público feminino foi o que mais se interessou por ora-pro-nobis e probióticos, apontando para um nicho de potenciais consumidores do produto.

Compostos clorados são amplamente utilizados na indústria de alimentos com a finalidade de eliminar microrganismos patogênicos e reduzir os alteradores até níveis considerados seguros. Dentre eles, se encontra o dióxido de cloro que possui a vantagem de reagir menos com a matéria orgânica. O presente estudo objetivou avaliar a ação antagônica do dióxido de cloro frente a patógenos. O teste de difusão em placa foi realizado com os quatro principais microrganismos que podem causar doenças de origem alimentar: Salmonella ssp, Escherichia coli, Listeria monocytogenes e Staphylococcus aureus e foram utilizadas quatro concentrações do dióxido de cloro (50; 100; 150 e 200 ppm). A concentração de 50 ppm não inibiu os patógenos avaliados. Com o aumento da concentração observou-se que o halo de inibição frente aos patógenos estudados também aumentou, indicando eficiência desse sanitizante.

Objetivo: Comparar desfechos obstétricos desfavoráveis entre a população negra brasileira e negra haitiana.
Métodos: Trata-se de um estudo observacional de coorte transversal abrangendo uma amostra composta por 662 mulheres, autodeclaradas negras, com gestação única, sendo 48,9% brasileiras e 51,1% haitianas, que tiveram seus bebês entre 01/04/2019 e 31/12/2021 na Maternidade Darcy Vargas.
Resultados: Foram analisados desfechos gestacionais, tanto maternos como fetais, desfavoráveis. Na avaliação de desfechos fetais houve diferença significativa na comparação de peso médio ao nascimento (negras brasileiras 3.148,7 kg vs negras haitianas 3.077,0 kg, p<0.05). Não houve diferença nas outras variáveis estudadas, porém é possível notar uma tendência a significância por uma maior prevalência de desfechos desfavoráveis em gestantes negras haitianas.
Conclusão: Na comparação dos desfechos obstétricos foi encontrado menor peso fetal entre gestantes negras haitianas, além da tendência de outros desfechos desfavoráveis nesta mesma população.

A pesquisa teve como objetivo diagnosticar geo-helmintos com potencial zoonótico em solo de praças públicas e escolas com presença de parques no município de Mossoró, Rio Grande do Norte. A metodologia proposta teve como critério de inclusão a presença de parques infantis alocados sobre areia, onde foram selecionadas 100% dos locais com esses critérios, sendo 30 praças e quatro escolas. Em cada ponto foram realizadas cinco coletas de areia superficial e profunda, com utilização das técnicas de sedimentação e flutuação, totalizando 150 amostras nas praças e 20 nas escolas. Como resultado foi verificado que, no ambiente escolar, das 20 amostras coletadas 25% (5/20) estavam positivas. Entre os endoparasitos na fase de ovo foram diagnosticados 40% (2/5) Trichuris spp., 40% (2/5) Dipylidium spp e 20% (1/5) Toxocara spp. Enquanto nas praças foram diagnosticados mais de um parasito por amostra sendo que diagnosticou-se na fase de ovo Ancylostoma spp. 48.6% (73/150), Toxocara spp. 32.6% (49/150) e Ascaris spp. 20.6% (31/150) enquanto na fase larval Strongyloides spp. 3.33% (5/150) e Ancylostoma spp. 38% (57/150). Concluindo que tanto as escolas como as praças públicas pesquisadas apresentaram parasitos patogênicos com importância para a saúde pública, representando risco para a saúde das crianças que socializam nesses espaços.

Ostras do gênero Crassostrea apresentam vasta distribuição territorial e têm grande importância econômica em virtude do seu valor nutricional. O substrato de fixação é um dos fatores relevantes para estes bivalves, pois suas larvas só podem se desenvolver após encontrar um meio adequado para dar início a sua metamorfose e virar um organismo adulto. A classificação taxonômica das ostras do gênero Crasssostrea do Atlântico ainda se demonstra confusa, justificando a necessidade em pesquisas nesta área. O presente artigo realizou a identificação molecular de ostras da costa do estado do Maranhão e investigou os substratos de fixação preferidos por estes moluscos. Ostras adultas foram coletadas em ambientes diferentes de três municípios maranhenses (São José de Ribamar, Primeira Cruz e Tutóia) e identificadas por meio da técnica de PCR Multiplex, utilizando como marcadores moleculares os genes COI e ITS1. As espécies Crassostrea rhizophorae e Crassostrea gasar foram identificadas nos dois pontos de coleta em São José de Ribamar, coexistindo tanto em ambiente de mangue como substrato rochoso. Nos municípios de Primeira Cruz e Tutóia, foi encontrada apenas a espécie Crassostrea gasar, em manguezal e material rochoso, respectivamente. A PCR Multiplex demonstrou-se promissora para a identificação de espécies de ostras com semelhanças morfológicas e nativas do litoral do Maranhão, podendo contribuir no monitoramento e entendimento da distribuição destes bivalves na costa do Brasil. A espécie C. gasar é bem distribuída na costa maranhense, com ocorrência em todos os pontos avaliados e em diferentes substratos.
