ABSTRACT: Anticarsia gemmatalis (Lepidoptera: Erebidae) is distributed in tropical and subtropical regions of America, and is an important pest of Fabaceae, such as: soybean, peanut, common bean, cowpea, pea, chickpea and kudzu. In soybean, the velvet bean caterpillar is important due to the plant defoliation in their larval stage. This study evaluated soybean cultivars as source of resistance to A. gemmatalis by antixenosis (attractiveness and non-preference for feeding) and antibiosis (biological parameters of the insect). The parameters evaluated were: antixenosis: attractiveness and non-preference, dry mass consumed and attractiveness index and antibiosis: duration of larval and pupal stages, adult longevity, total cycle, larval and pupal weights and larval, pupal and total viability. Considering antixenosis and antibiosis the least suitable cultivars for A. gemmatalis were found to be BRS 8383 IPRO, BRS 1074 IPRO, BRS 1061 IPRO, BRS 7180 IPRO, BRS 9383 IPRO, BRS 8980 IPRO and BRS 1003 IPRO due to high mortality in the larval phase. The cultivars BRS 523 and BRS 543 RR “block technology” suggest displays antixenosis and or antibiosis to A. gemmatalis. These cultivars can be used by soybean producers in combination with other control tactics in soybean IPM.

RESUMO: Anticarsia gemmatalis (Lepidoptera: Erebidae) está distribuída nas regiões tropicais e subtropicais da América, trata-se de importante praga de Fabaceae, como: soja, amendoim, feijão, feijão-caupi, ervilha, grão de bico e kudzu. Na soja, a lagarta-da-soja é importante devido à desfolha da planta em sua fase larval. O objetivo deste trabalho foi avaliar cultivares de soja como fonte de resistência a A. gemmatalis por antixenose (atratividade e não-preferência para alimentação) e antibiose (parâmetros biológicos do inseto). Os parâmetros avaliados foram: antixenose: atratividade e não-preferência, massa seca consumida e índice de atratividade e antibiose: duração dos estágios larval e pupal, longevidade de adultos, ciclo total, peso larval e pupal e viabilidade larval, pupal e total. Na antixenose e antibiose os cultivares menos favoráveis a A. gemmatalis foram: BRS 8383 IPRO, BRS 1074 IPRO, BRS 1061 IPRO, BRS 7180 IPRO, BRS 9383 IPRO, BRS 8980 IPRO e BRS 1003 IPRO devido à alta mortalidade larval. Os cultivares BRS 523 e BRS 543 RR “Tecnologia block” apresentaram antixenose e/ou antibiose a A. gemmatalis. Essas cultivares podem serem utilizadas por produtores de soja em combinação com outras táticas de controle no MIP.

Resumen Objetivo: Analizar los componentes subyacentes de las presiones inspiratorias (MIP) y espiratorias (MEP) es táticas máximas reducidas en sujetos con distrofia de Duchenne (DMD). Métodos: Se evaluaron 43 pacientes mediante pruebas de función pulmonar rutinarias. MIP y MEP fueron medidas a inspiración y espiración máximas. Los volúmenes pulmonares se midieron mediante dilución de helio. Resultados: Edad media 13 años (rango 7-20 años). La capacidad pulmonar total (TLC) y el volumen residual (RV) fueron 78.0% (49.0-94.0) y 27.0% (19.7- 30.1) de los valores predichos. El RV/TLC fue de 35.3% (28.1-47.7). Treinta y cinco sujetos tenían una TLC por debajo del límite inferior de normalidad, 31 tenían una RV/TLC por encima del límite superior de la normalidad. MIP y MEP fueron -53.0 (-65.5 a -41.8) y 58.0 (41.5-74.8) cmH2O, mientras que en % de los predichos (TLC y RV predichos) fueron 42.6 (33.3-50.8) y 33.7 (23.9-44.5). MIP en % del RV alcanzado (Grupo A 7-11 años) fue mayor (p 0.025), y MEP en % de la TLC alcanzada Grupo B (12-16 años) y C (17-20 años), también fue mayor (0.031). Conclusiones: En sujetos con DMD, debilidad intrínseca de los músculos respiratorios y desventaja mecánica conducen a generación de presión estática máxima inadecuada. Las mismas deben interpretarse con cautela, ya que sobrestiman la debilidad de los músculos respiratorios si se las compara con las tablas de valores predichos obtenidos a TLC y RV. Nuestros resultados proporcionan datos adicionales que respaldan la utilización de valores absolutos en lugar de los predichos.

Abstract Objective: To analyze the underlying components of reduced maximal static inspiratory (MIP) and expiratory (MEP) pressures in subjects with Duchenne muscular dystrophy. Methods: Forty-three subjects were assessed based on routine pulmonary function tests. MIP and MEP were measured the subjects performed maximal expirations and inspirations using a snorkel mouthpiece. Lung volumes were measured us ing the helium dilution technique. Results: The mean age was 13 years (range, 7-20 years). Median total lung capacity (TLC) and residual volume (RV) were 78.0 (49.0-94.0) and 27.0 (19.7-30.1) of the predicted values re spectively. The RV/TLC relationship was 35.3% (28.1-47.7). Thirty-five subjects had a TLC below the lower limit of normal, while 31 had an RV/TLC ratio above the upper limit of normal. The median (IQR) MIP and MEP values were -53.0 (-65.5 to -41.8) and 58.0 (41.5-74.8) cmH2O respectively. MIP and MEP in percent of the predicted values (predicted TLC and RV) were 42.6 (33.3-50.8) and 33.7 (23.9-44.5). MIP in percent of the RV reached for Group A (7-11 years old) was higher (p 0.025) while MEP in percent of the TLC reached for Group B (12-16 years) and C (17-20 years) were higher too (0.031). Conclusions: In subjects with Duchenne muscular dystrophy, the intrinsic weakness of respiratory muscles and mechanical disadvantage lead to inadequate maximal static pressure generation. Maximal static pressures should be interpreted cautiously as they overestimate respiratory muscle weakness when compared to predicted values obtained at TLC and RV. Our results provide additional data supporting absolute values use rather than predicted values.

Resumo: O artigo caracterizou a adoção do Manejo Integrado de Pragas (MIP) na produção paulista de laranja a partir do LUPA 2016/2017. Para tanto, buscou apoio nas construções teóricas e conceituais sobre mudança tecnológica e MIP, para conduzir análise pautada no cenário de produção, comercialização, organizacional e de P&D da cultura da laranja, assim como do tratamento e análise de informações censitárias, LUPA 2016/2017, no recorte do MIP e da produção de laranja. Os resultados apontam o forte posicionamento internacional do suco de laranja brasileiro e paulista, associado a uma ampla e consolidada estrutura de representação da agroindústria e da produção agrícola, bem como das atividades públicas e privadas de P&D. Esses resultados convivem com a limitada oferta de tecnologias para solução dos principais problemas fitossanitários da cultura. Nesse ambiente, o MIP toma espaço como alternativa viável e importante, estando presente em 40% da área e pés em produção, em propriedades em que a laranja é a principal fonte de renda familiar, com proprietários que possuem maior nível educacional e são cooperados ou associados. O MIP também foi relacionado a outras tecnologias, a exemplo do uso de mudas certificadas e do crédito e seguro rural.

Abstract: The article characterized the adoption of Integrated Pest Management (IPM) in orange production in São Paulo from LUPA 2016/2017. To this end, it sought support in theoretical and conceptual constructions on technological change and MIP, to conduct an analysis based on the production, commercialization, organizational and R&D scenario of the orange crop, as well as the treatment and analysis of census information, LUPA 2016/ 2017, in the cut of MIP and orange production. The results point to the strong international positioning of Brazilian and São Paulo orange juice, associated with a broad and consolidated structure of representation of agro-industry and agricultural production, as well as public and private R&D activities. These results coexist with the limited supply of technologies to solve the main phytosanitary problems of the crop. In this environment, MIP takes place as a viable and important alternative, being present in 40% of the area and plants in production, in properties where orange is the main source of family income, with owners who have a higher educational level and are cooperative or associated. . The MIP was also related to other technologies, such as the use of certified seedlings and rural credit and insurance.

The Brazilian regulations for processed coconut water establish the range concentrations of Na and K, being necessary high-throughput analytical methods, as microwave-induced plasma optical emission spectrometry (MIP OES) for quality control. Samples of natural (green and mature) and processed coconut water were treated by acid decomposition assisted by microwave radiation before their MIP OES analysis. Recoveries for Na and K were 103 and 95%, whereas the relative standard deviation (RSDs) were 7.6 and 1.3%, respectively. The limit of detection (LOD) was 1.77 mg kg-1 for K and 2.31 mg kg-1 for Na. Na and K were determined in the ranges of, respectively, 27-490 and 1,600-3,500 mg L-1 in natural samples, whereas in processed samples the ranges were 26-168 and 814-2,054 mg L-1. K-means cluster analysis identified a group of processed samples with compositions similar to green coconut water. All the processed samples were in accordance with the established regulation, except one dehydrated sample for which K content was below the accepted range. Natural coconut water is an excellent source of K in the diet as its daily consumption can supply more than 20% of the recommended daily ingestion of K for adults and 30% for children.

Abstract Objective: This study aims to evaluate the respiratory function of children and adolescents with osteogenesis imperfecta (OI) followed up at a referral center. Methods: A cross-sectional study was conducted with a non-probabilistic sample. Manovacuometry was performed with the measurement of maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP), and in addition, peak expiratory flow (PEF) and ventilometry were performed to measure forced vital capacity (FVC). Results: In total, 23 individuals were evaluated, with a mean age of 11.6±3.4 years, 56.5% of whom were females. Regarding the classification of OI, 56.5% of the sample belonged to type IV, 30.5% to type III, and 13% to type I. The mean MIP was 64.4% of the predicted, and the mean MEP was 56.2% of the predicted. Overall, the mean PEF was 213.9 L/min, but only 140.6 L/min in the OI type III group. Median FVC was 1.9 L, corresponding to 110% of the predicted. Conclusions: Respiratory function of the study subjects was altered, with respiratory muscle strength values lower than expected in the whole sample, and peak expiratory flow was significantly reduced in the OI type III group.

Abstract This study, about RPW and date palms, is under the scope of date palm bioecology and nutrition (nutritional ecology) which includes the integration of several areas of research such as date palm biochemistry, genetics, and RPW infestation behavior through various date palm cultivars. Date palm (Phoenix dactylifera L.; Arecaceae) production is under threat from the red palm weevil (RPW), Rhynchophorus ferrugineus Oliver. A better understanding of genetic diversity within date palm cultivars can be useful for its implementation within the insect IPM program in the future. Three indices, namely simple-sequence repeats (SSR) markers to elucidate genetic diversity, chemical components, and a natural infestation index of RPW, were used to evaluate the resistant or susceptible date palm cultivars in Qassim. Based on a field survey of RPW infestation within 79 date palm farms involving 11 cultivars at Qassim, the sensitivity and resistance cultivars were determined. The resistant date palm cultivars were Nabtat Ali, Shakrah, red Sukary, and um Kobar which had the lowest degree of RPW abundance %. Values of the essential minerals, nitrogen, phosphorus, potassium, and calcium within the date palm cultivars were also estimated. RPW abundance % was negatively correlated with the calcium content of date palm cultivars. The principal component analysis (PCA) revealed that the calcium content and RPW abundance % were highly affected by the cultivars. SSR markers of the date palm cluster tree divided genotypes into two main groups at similarity coefficients between 0.56 and 0.91. The 1st group included; Nabtet Ali, Red Sukary, Um Kobar, and Shakrah with similarity coefficients between 0.56, this group was the most resistant cultivars. Therefore, SSR markers were able to characterize and resolve genetic diversity in date palm cultivars for RPW resistance. When SSR markers coupled with higher calcium (Ca) content can efficiently replace indices in characterizing resistant date-palm genotypes with a high confidence level. Integration between date palm genetic diversity, chemical structures, and RPW infestations rates promoted the understanding of the interplay between the diversity of RPW management (short-time scale), and the resistance genes, plant nutrition, and dynamics of the diversity of RPW through domestication and diversification (long-timescale). Therefore, our results may lead to a change in RPW control strategies by switching to using safe alternative pesticide control methods (Resistant cultivars of date palm), which are underestimated and may reveal the impact of low-cost, but highly effective agricultural practices in the field of date production in the world. Understanding the genetic structure and calcium content of date palm cultivars mechanisms could help to predict date palm resistance against RPW populations in the new IPM strategy in RPW control.

Resumo Este estudo, sobre RPW e tamareiras, está no âmbito da bioecologia e nutrição da tamareira (ecologia nutricional) que inclui a integração de várias áreas de pesquisa, como bioquímica da tamareira, genética e comportamento de infestação de RPW através de vários cultivares de tamareira. A produção da tamareira (Phoenix dactylifera L.; Arecaceae) está ameaçada pelo gorgulho vermelho da palmeira (RPW), Rhynchophorus ferrugineus Oliver. A compreensão mais aprofundada da diversidade genética dentro dos cultivares de tamareiras pode ser útil para sua implementação no futuro programa de MIP de insetos. Três índices, ou seja, marcadores de sequência simples (SSR) para elucidar a diversidade genética, componentes químicos e um índice de infestação natural de RPW, foram utilizados para avaliar as cultivares de tamareiras resistentes ou suscetíveis em Qassim. Com base em uma pesquisa de campo da infestação de RPW em 79 fazendas de tamareiras envolvendo 11 cultivares em Qassim, as cultivares de sensibilidade e resistência foram determinadas. As cultivares de tamareiras resistentes foram Nabtat Ali, Shakrah, red Sukary e um Kobar, que apresentaram o menor grau de abundância de RPW. Também foram estimados os valores dos minerais essenciais, nitrogênio, fósforo, potássio e cálcio nas cultivares de tamareira. A porcentagem de abundância de RPW correlacionou-se negativamente com o teor de cálcio das cultivares de tamareira. A análise de componentes principais (PCA) revelou que o teor de cálcio e a abundância de RPW % foram altamente afetados pelas cultivares. Marcadores SSR da tamareira dividiram os genótipos em dois grupos principais com coeficientes de similaridade entre 0,56 e 0,91. O 1º grupo incluiu; Nabtet Ali, Red Sukary, Um Kobar e Shakrah com coeficientes de similaridade entre 0,56, este grupo foi o de cultivares mais resistentes. Portanto, os marcadores SSR foram capazes de caracterizar e resolver a diversidade genética em cultivares de tamareiras para resistência a RPW. Quando os marcadores SSR associados ao maior teor de cálcio (Ca) podem substituir com eficiência os índices na caracterização de genótipos de tamareiras resistentes com alto nível de confiança. A integração entre diversidade genética da tamareira, estruturas químicas e taxas de infestação de RPW promoveu a compreensão da interação entre a diversidade de manejo de RPW (escala de tempo curto) e os genes de resistência, nutrição de plantas e dinâmica da diversidade de RPW por meio da domesticação e diversificação (longo prazo). Portanto, nossos resultados podem levar a uma mudança nas estratégias de controle de RPW, passando a usar métodos alternativos seguros de controle de pesticidas (cultivares resistentes de tamareira), sendo subestimados e podem revelar o impacto de práticas agrícolas de baixo custo, mas altamente eficazes no campo de produção de tâmaras no mundo. Compreender a estrutura genética e o teor de cálcio dos mecanismos dos cultivares de tamareira pode ajudar a prever a resistência da tamareira contra populações de RPW na nova estratégia de IPM no controle de RPW.

Abstract The fall armyworm [FAW; Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae)], is considered a serious invasive pest that poses a serious threat to world food security. It can completely devastate a whole country's cereal crops. Therefore, the present work is the 1st field trial in Egypt to elucidate some ecological aspects of S. frugiperda on maize plants (Single-Hybrid 168 Yellow Corn cultivar) at Esna district, Luxor Governorate, Egypt, throughout two sequential growing seasons of maize (2021-2022). Three insect parameters were used, i.e., egg masses, number of larvae, and percentage of damaged corn plants. Effects of certain climatic conditions and corn plant ages on S. frugiperda seasonal activity and damaged plants percentage were also estimated. S. frugiperda population initiated to attack maize plants from the 3rd week of June until the harvest in every season. S. frugiperda had two seasonal activity peaks in terms of egg masses numbers and three peaks regarding the larval population density/season. Its damage percentage increased with increasing plant age weekly. The mean of S. frugiperda egg masses were 2.83 ± 0.40 and 2.96 ± 0.45 mass /10 corn plants in 2021 and 2022, respectively. While, the overall mean larval populations were 13.41 ± 0.52 and 13.03 ± 0.46 larvae/10 plants, during the two growing seasons, respectively. Corn plant damage percentages reached 68.54 ± 2.71 and 60.42 ± 2.92% in 2021 and 2022, respectively. The combined effects of both the weather conditions and maize plant ages were highly significant on egg masses, larvae population density, and damage percentage, and varied from one season to another. The mean daily maximum temperature was the most effective variable on egg masses and the larval population. Maize plant age had a clear effect on the damage percentage caused by the larvae in the field during the two years of the study. The dramatic spread of FAW and the consequent damage (that appeared in different countries of America, Africa, and Asia) mean that different management approaches must be sought for the small and large-scale producers by using available technologies for smallholder farmers will eliminate pest damage without access to reach to an economic Injury level. This information may assist the decision maker when planning the S. frugiperda IPM program for maize plants and its surveillance.

Resumo A lagarta-do-cartucho [FAW; Spodoptera frugiperda (Smith) (Lepidoptera: Noctuidae)], é considerada uma séria praga invasora que representa uma séria ameaça à segurança alimentar mundial. Essa espécie pode devastar completamente as plantações de cereais de um país inteiro. Portanto, o presente trabalho é o primeiro ensaio de campo no Egito para elucidar alguns aspectos ecológicos de S. frugiperda em plantas de milho (Single-Hybrid 168 Yellow Corn cultivar) no distrito de Esna, Luxor Governorate, Egito, ao longo de duas estações de crescimento sequencial de milho (2021 a 2022). Três parâmetros de insetos foram utilizados, isto é, massas de ovos, número de larvas e porcentagem de plantas de milho danificadas. Também foram estimados os efeitos de certas condições climáticas e idades das plantas de milho na atividade sazonal de S. frugiperda e na porcentagem de plantas danificadas. A população de S. frugiperda começou a atacar as plantas de milho a partir da terceira semana de junho até a colheita em todas as estações. S. frugiperda apresentou dois picos sazonais de atividade como o número de massas de ovos e três picos em relação à densidade populacional larval/estação. Seu percentual de dano aumentou semanalmente a partir do aumento da idade da planta. A média das massas de ovos de S. frugiperda foi de 2,83 ± 0,40 e 2,96 ± 0,45 massa/10 plantas de milho em 2021 e 2022, respectivamente. Enquanto, as populações larvais médias gerais foram de 13,41 ± 0,52 e 13,03 ± 0,46 larvas/10 plantas, durante as duas estações de crescimento, respectivamente. As porcentagens de danos às plantas de milho atingiram 68,54 ± 2,71 e 60,42 ± 2,92% em 2021 e 2022, respectivamente. Os efeitos combinados das condições climáticas e da idade das plantas de milho foram altamente significativos nas massas de ovos, densidade populacional de larvas e porcentagem de danos, e variaram de uma estação para outra. A temperatura média diária máxima foi a variável mais efetiva sobre as massas de ovos e a população larval. A idade da planta de milho influenciou visivelmente o percentual de dano causado pelas larvas no campo durante os dois anos de estudo. A propagação dramática da LFM e os danos consequentes (que apareceram em diferentes países da América, África e Ásia) significam que devem ser utilizadas diferentes abordagens de gestão para os pequenos e grandes produtores, a partir de tecnologias disponíveis para os pequenos agricultores eliminarem os danos causados pelas pragas sem acesso para chegar a um nível de dano econômico. Essas informações podem auxiliar o tomador de decisão no planejamento do programa MIP de S. frugiperda para plantas de milho e o seu monitoramento.

Abstract This study explored effects of microbial preparation (MIP, developed by our research team) on production performance and body health of Boer goat to reveal the function of it in goat breeding industry. Compound yeast and enzyme preparation (CYP) was used to compare the function of MIP. Healthy male Boer goats (n = 15, BW = 25.31±4.06 kg) were allocated randomly into three groups as NC (Basal diet), MI (Basal diet + MIP) and CY (Basal diet + CYP). This study lasted for 71 days including 15 days for adaptation and 56 days for growth trial. Both MIP and CYP enhanced production performance such as average daily gain of goats, MIP enhanced the level of fat synthesis such as total cholesterol level significantly on day 28. As for rumen fermentation and microbial communities of goat, MIP decreased rumen pH. PCoA analysis showed that the rumen bacterial community on day 28 was significantly separated. In conclusion, MIP increased production performance, ameliorating rumen fermentation and shifting microflora. Our findings provide the evidence for the influence of probiotics on goat production performance as well as health condition.

Abstract Introduction Coronary artery bypass grafting (CABG) surgery is associated with a decline in ventilatory muscle strength and lung function. Inspiratory muscle training (IMT) based on anaerobic threshold (AT) has been used to minimize the impact of CABG on these parameters, but the long-term impact is unknown. Objective To test the hypothesis that AT-based IMT improves inspiratory muscle strength and lung function even six months after CABG. Methods This is a randomized controlled clinical trial. In the preoperative period, maximum inspiratory pressure (MIP), maximum expiratory pressure (MEP), vital capacity (VC) and peak expiratory flow (PEF) rate were assessed. On the first postoperative day, patients were randomized into two groups: AT-based IMT (IMT-AT) (n=21) where the load was prescribed based on glycemic threshold and conventional IMT (IMT-C) (n=21), with load of 40% of MIP. Patients were trained during hospitalization until the day of discharge and were assessed at discharge and six months later. For within-group comparison, paired Student's t-test or Wilcoxon test was used, and independent Student's t-test or the Mann-Whitney test was used to analyze the different time points. A p<0.05 was considered significant. Results At six months after CABG surgery, statistical difference was found between the IMT-AT and the IMT-C groups in MIP (difference between the means of -5cmH2; 95% CI=- 8.21to-1.79) and VC (difference between the means of -2ml/kg;95%CI=-3.87to-0.13). No difference was found between groups in the other variables analyzed. Conclusion IMT-AT promoted greater recovery of inspiratory muscle strength and VC after six months of CABG when compared to conventional training.

Abstract Background Frailty is a biological syndrome suggested as a better predictor of morbimortality than chronological age. Objective To assess associations between frailty and morbimortality outcomes in postoperative cardiac surgery. Methods A retrospective cohort study was conducted with cardiac surgery patients. Frailty and maximal inspiratory pressure (MIP) were assessed before surgery. Postoperative outcomes were: extracorporeal circulation time; use of vasopressor; mean arterial pressure (MAP); red blood cell (RBC) transfusion; cardiac arrhythmia and/or heart arrest; presence of intra-aortic balloon pump; antibiotic use; extubation time; length of stay in the intensive care unit (ICU); length of postoperative stay; mortality. One-way ANOVA was used to compare postoperative variables between frailty categories; Spearman was used to evaluate the correlations between frailty and postoperative variables. Age, sex, and MIP were introduced into multiple regression models to find the independent association between postoperative variables and frailty. A significance level of p < 0.05 was adopted. Results The medical records of 200 patients were analyzed (65.7±7.2 years; 68.5% men; 63.5% non-frail, 22.5% pre-frail, 14% frail). Frailty was not a predictor of postoperative outcomes. Age was an independent predictor for alterations in MAP (PR: 1.028, 95% CI: 1.003-1.053, p=0.025), need for RBC transfusion (PR: 1.034, 95% CI: 1.007-1.062, p=0.014), longer extubation time (PR: 1.052, 95% CI: 1.023-1.083, p<0.001), length of stay in the ICU (ß: 0.031, 95% CI: 0.010-0.053, p=0.005), length of postoperative stay (ß: 0.017, 95% CI: 0.003-0.031, p=0.015). Conclusions Frailty was not a predictor of morbimortality following cardiac surgery in middle-aged and older adults; however, age did predict morbidities in this setting.

Resumen El Manejo Integrado de Plagas (MIP) es un enfoque de control de plagas que considera todas las estrategias disponibles y su posterior integración para el control de plagas. Entre sus estrategias se destacan el Control Biológico (CB) mediante el uso de enemigos naturales. El control biológico por depredadores generalistas ha cobrado relevancia en la última década. Esta estrategia por aumento exige la cría masiva de estos organismos. En la Región Neotropical, Chrysoperla externa (Neuroptera: Chrysopidae) tiene gran importancia por su alta voracidad y su amplia gama de hospederos. El objetivo de este estudio fue describir los cambios externos de los huevos, especialmente en color y forma, asociados al desarrollo intracoriónico de embriones de C. externa, para caracterizarlos morfo-colorimétricamente. Se construyó una clave práctica a partir de la determinación de su desarrollo embrionario como herramienta para la técnica de cría masiva. Esta clave proporciona información valiosa que facilitaría la implementación de CB para programas de MIP en regiones en desarrollo, donde aún es incipiente.

Abstract Integrated Pest Management (IPM) is a pest control approach that considers all available strategies and their subsequent integration for pest control. The Biological Control (BC) of pests through the use of natural enemies is an outstanding strategy. Biological control by generalist predators has had a highlighted relevance in the last decade. This strategy by augmentation demands mass rearing of these organisms. In the Neotropical Region Chrysoperla externa (Neuroptera: Chrysopidae) is of great importance for its high voracity and its wide range of hosts. The aim of this study was to describe the external changes of the eggs, especially in colour and shape, associated with the intrachorionic development of C. externa embryos, to characterize them morpho-colorimetrically. A practical key from its embryonic development determination was constructed as a tool for mass rearing technique, providing valuable information that could facilitate BC implementation for IPM programs in developing regions.

Abstract Molecularly imprinted polymers (MIPs) are an important class of compounds with wider sensing applications for the determination of substances ranging from small molecular masses to macro size. The hyphenation of MIP principle with other likewise conducting polymers yields the devices for sensing purposes. MIPs are robust against environmental conditions, more economical than natural receptors, and their preparation is also adequate for substances without natural receptors. Organic mediated MIPs compounds are of current interest, due to their applicability as quantification tools to determine electroactive substances in a variety of real samples. MIPs are highly selective for target molecules, mechanically strong, resistant to temperature and pressure, inert towards acids, bases, metal ions and organic solvents, highly stable for longer periods, and operative at room-temperature. Therefore, during past years, MIPs have been used as electrochemical and optical sensors, sorbents, solid phase media, and so on. Herein, there is a focus on the use of Pyrrole (Py) as a monomeric molecule to fabricate MIPs. Py or poly-Py (p-Py) based MIPs are synthesized and used in various capacities as chemo electrochemical sensors. A detailed discussion on the application of Py-mediated MIPs for the electrochemical determination of some organic compounds of therapeutic and environmental interest is herein presented as a review.

Abstract This article aims to investigate the association between maximal inspiratory pressure (MIP) and maximal expiratory pressure (MEP) with the incidence of frailty syndrome (FS), in addition to testing the predictive ability of MIP and MEP to discriminate FS in elderly adults, according to sex. It is a longitudinal study with a five-year follow-up period (2014-2019), carried out with 104 elderly adults registered in the Family Health Strategy of a municipality in Bahia. The incidence of frailty syndrome was diagnosed according to criteria proposed by Fried et al., using data from 2019, after a five-year follow-up. The MIP and MEP were evaluated according to the recommendations of the Brazilian Society of Pulmonology and Phthisiology data in 2014 (baseline data). The total incidence of frailty syndrome was 16.3% (95%CI: 9.2-23.6), with 13.6% (95%CI: 4.56-22.55) in women and 20% (95%CI: 7.85-32.15) in men. The mean values of MIP and MEP were, respectively, 60,8±21,2 cmH2O and 76,7±23,1 cmH2O in women, and 79,5±27,0 cmH2O and 114,7±29,8 cmH2O in men. The frailty syndrome was associated with MEP in elderly adult men (adjusted RR: 0.96; 95%CI: 0.95-0.98; P-value: 0.002), indicating that the increase of 1cmH2O in MEP reduces by 4% the risk of developing the syndrome.

Resumo O objetivo deste artigo é investigar a associação entre a Pressão Inspiratória Máxima (PImáx) e Pressão Expiratória Máxima (PEmáx) com a incidência da síndrome de fragilidade (SF), além de testar a capacidade preditiva da PImáx e PEmáx em discriminar a SF em idosos, de acordo com o sexo. Estudo longitudinal com cinco anos de seguimento (2014-2019), realizado com 104 idosos cadastrados na Estratégia Saúde da Família de um município da Bahia. A incidência da síndrome de fragilidade foi diagnosticada de acordo os critérios propostos por Fried et al., utilizando dados de 2019, após cinco anos de seguimento. A PImáx e PEmáx foram avaliadas conforme recomendações da Sociedade Brasileira de Pneumologia e Tisiologia em 2014 (linha de base). A incidência total da SF foi de 16,3% (IC95%: 9,2-23,6), sendo 13,6% (IC95%: 4,56-22,55) no sexo feminino e 20,0% (IC95%: 7,85-32,15) no sexo masculino. Os valores médios da PImáx e PEmáx foram, respectivamente, 60,8±21,2 cmH2O e 76,7±23,1 cmH2O no sexo feminino, e 79,5±27,0 cmH2Oe 114,7±29,8 cmH2O no sexo masculino. A SF esteve associada à PEmáx em idosos do sexo masculino (RR ajustado: 0,96; IC95%: 0,95-0,98; p-valor: 0,002), indicando que o aumento de 1 cmH2O da PEmáx reduz em 4% o risco de desenvolver a síndrome de fragilidade.
