Análise da eficiência do carvão ativado da vagem de algaroba (Prosopis juliflora) como adsorvente na remoção de gasolina em corpos d’água.
Authors:   , Maria Silva Paiva Ana
Published: July 2023

Os problemas relacionados a contaminações ambientais são uma temática importante e foco de pesquisas, principalmente quando envolve recursos fundamentais tais como a água, que é vital para a vida. Contaminações decorrentes de vazamentos industriais representam um grande problema quando o contaminante é gasolina, uma vez que sua composição pode ser nociva para a saúde. Sendo assim, a adsorção surge como um método extremamente eficaz e viável, visto que as possibilidades de biomassas encontradas com facilidade na natureza serem aplicadas são reais e acarretam em baixo custo do processo. No presente caso, foi utilizada a algaroba (Prosopis juliflora), que se mostrou eficiente nas pesquisas de Lima e Farias (2019; 2020). A partir destes resultados e revisando a literatura, foi deduzido que a aplicação de carvão ativado poderia aumentar a eficiência de adsorção da biomassa vagem de algaroba na remoção de gasolina presente em água. Desse modo, o objetivo deste trabalho foi avaliar a capacidade de adsorção do carvão ativado de vagem de algaroba como agente adsorvente para a remoção do hidrocarboneto e fazer uma comparação entre a biomassa in natura, com o carvão ativado fisicamente (CAF) e com o carvão ativado fisicamente e quimicamente (CAFQ), com relação à quantidade de contaminante removido da água. Para a preparação do carvão ativado fisicamente (CAF), a algaroba foi seca em estufa, depois moída em moinho de facas, seguindo para a carbonização em mufla por 30 minutos a 500°C. Para a ativação química, o CAF foi submetido à agitação com uma solução de hidróxido de potássio (KOH) por 30 minutos sob agitação de 140 rpm. A metodologia utilizada para o estudo da cinética e do equilíbrio foi proposta por Lima et al. (2014). Foram realizados os experimentos para o estudo da cinética de adsorção, em que foram avaliados os tempos de 05 a 60 minutos (com intervalos de 5 minutos) e o equilíbrio de adsorção, cujas concentrações de contaminantes variaram de 5 a 50% (com taxa de variação de 5%). Nos resultados da cinética, a adsorção máxima do CAF ocorreu aos 30 minutos (5,000 g.g-1), e do CAFQ, aos 25, 50 e 60 minutos (5,000 g.g-1). No equilíbrio, a quantidade máxima adsorvida com a presença do CAF foi de 7,13 g.g-1, com concentração de 31,06% de contaminante, enquanto para o CAFQ, foi de 7,13 g.g-1, com concentração de 32,44%. As isotermas confirmaram que a adsorção do CAF ocorreu em monocamada e a do CAFQ em multicamadas. Contudo, pode-se afirmar que a ativação com KOH foi ineficiente para o carvão da vagem de algaroba, visto que o resultado com o material in natura atingiu um máximo de 14,812 g.g-1 no equilíbrio, com concentração de 15,78%.

Authors:   , Ivoneide de Oliveira Araújo Maria
Published: July 2023

O presente trabalho teve como objetivo analisar as causas da evasão escolar no Ensino Médio da Escola Estadual de Ensino Fundamental e Médio Professor José Gonçalves de Queiroz, no Município de Sumé/PB, no período de 2008 a 2010. As motivações para o estudos partiram do fato de observar que aos educandos desapareciam das salas de aulas, sem questionamentos ou intervenções. Ao ingressar no apoio pedagógico da escola, com acesso a documentos – diários de classe, fichas individuais, boletins, resultado final, censo escolar – ficou perceptível os números, e surgiu a preocupação, por constatar que era algo repetitivo, mas que nada era feito para reverter o quadro. Para esta pesquisa, utilizou-se como via metodológica a pesquisa qualitativa, centrando o trabalho investigativo no Estudo de Caso, a partir do diário de campo, da observação participante, da análise documental e de entrevistas. Elegeu-se como público alvo os segmentos discente e docente da referida escola. Como resultado a pesquisa apontou um elevado índice de evasão escolar, que segundo educandos e educadores é reflexo do desinteresse, da indiferença, da necessidade de trabalho, da gravidez precoce, da falta de incentivo da família. Foi comprovado que poucos educandos retornaram no ano seguinte (2011) e a escola continua seu trabalho sem estratégias que revertam esse problema.

Biblical wisdom: rethinking Christian education according to Proverbs 1:2-7 and its relationship with national education philosophy
Authors: Latuihamallo Yulianus , Nassa Grace Son
Published: July 2023

The purpose of this study is to discover the significance of biblical wisdom according to Proverbs 1:2-7 in Christian education and to use it as a point of view when highlighting the national education philosophy, as well as to see whether the nature of the two complement each other or sharpen each other when they meet? The method used was a combination of theological interpretation of Proverbs 1:2-7 and a synchronic perspective on the philosophy of the national education motto. This research found that Christian education has two sides when it meets the philosophy of the national education motto. First, Christian education remains based and aims at biblical wisdom, next, it can be open to the philosophy of the motto but applies analytical rigor and criticality.

Published: July 2023

At present, the issues of the relationship between non-alcoholic fatty liver disease (NAFLD) and obesity, especially abdominal, as well as metabolic syndrome, which, in turn, significantly increases the cardiometabolic risk and affects the incidence, prognosis and life expectancy of patients, are quite well studied. And although the prevalence of various clinical forms of NAFLD is significantly higher in obese patients than in the general population, 7–20 % of people with NAFLD are estimated to have a lean body habit. At the same time, the rate of disease progression, associated conditions, anddiagnostic and management approaches differ for patients with NAFLD depending on body mass index (BMI), which reveals the need for clear guidance to clinicians regarding the NAFLD treatment depending on nutritional status. We performed a systematic review to summarize the clinical and metabolic aspects of NAFLD depending on nutritional status, as well as approaches to non-drug treatment through lifestyle changes. The fundamental clinical and functional, metabolic, hormonal and other factors of the pathological process that determine the mechanisms and prognosis of the disease in patients with NAFLD with different BMI are discussed. Information on the topic from publications based on the PubMed and RSCI databases was used.

Published: July 2023

Aim. To detect intestinal ischemia promptly in patients with acute adhesive small bowel obstruction.

Methods. A total of 124 patients with acute adhesive small bowel obstruction were studied. Logistic regression analysis was performed to determine the most significant prognostic factors for intestinal ischemia. The derived regression coefficient indicators were utilized in a scoring system.

Results. Six independent prognostic factors of intestinal ischemia were identified: age, duration of pain, body temperature, white blood cell count, reduced intestinal wall contrast, and localized mesenteric edema visible on a CT scan. Regression coefficient scores were attributed to each variable associated with intestinal ischemia. The predicted occurrence of bowel ischemia was computed as a sum of scores ranging from 0 to 24. A threshold of 6 points was used to define the low-probability group (risk of bowel ischemia was 1.13%). A score between 7 and 15 determined the intermediate-probability group (the risk of intestinal ischemia was 44%). A score of ≥16 defined the high-probability group (all patients in this group had intestinal ischemia).

Conclusions. The risk prediction assessment of bowel ischemia was performed with high accuracy (above 90%). This evaluation is reliable and reproducible, hence it may aid the surgeon to differentiate patients with intestinal ischemia for surgical intervention. Since ischemic disorders may be reversible, this could prevent the development of intestinal necrosis.

A 60-year-old man developed, within a month, right thoracic pain, shortness of breath and weight loss. He had a history of working in a metallurgical company and was exposed to chemical paints. He was admitted into the emergency department and a chest computed tomography revealed a large solid mass at the left superior lung lobe, measuring 80 mm x 40 mm. A biopsy was performed and confirmed the diagnosis of Lung Adenocarcinoma. Cancer staging was performed and revealed liver, bone and brain metastases. The brain magnetic resonance imaging disclosed several metastatic lesions at the right postcentral gyrus, occipital lobes and both cerebellar hemispheres. He underwent whole brain radiation therapy and received five cycles of palliative chemotherapy (carboplatin in combination with paclitaxel, and gemcitabine in combination with cisplatin). A second biopsy was performed at the liver metastasis, to search for possible targeted therapies. The results came positive for Epidermal Growth Factor Receptor (EGFR) exon 19 deletion, and an anti-EGFR was prescribed. The patient was started on Osimertinib, 80 mg once a day. The one year follow up showed great response and good drug tolerance, with an important improvement of muscle strength, asthenia and sensory deficits. The patient became fully ambulatory with a Karnofsky Performance Status Scale score of 90 and on the Neurologic Assessment in Neuro-Oncology Scale a score of 3 out of 23. Imaging studies revealed a smaller number of brain metastatic lesions, with decreased contrast enhancement. Therefore, the patient has had a dramatic response to the targeted therapy, both clinical and imaging. Targeted therapy is a growing field in neuro-oncology, leading us to an era of personalized medicine and tailored treatments, with great improvement in overall survival and quality of life. Unfortunately, in Brazil targeted therapies are still not widely available, due to high costs.

El objetivo del estudio fue comparar la fertilidad seminal y taza de preñes en un hato de ovinos katahdin mediante inseminación laparoscópica con semen refrigerado y congelado en ambiente tropical, fueron utilizados el reproductor y veinte vientres de la raza katahdin. Se realizaron dos evaluaciones para valorar la calidad del semen de acuerdo con sus características macroscópicas y microscópicas y las hembras fueron sincronizadas con dispositivos intravaginales con 0.3 g de progesterona natural (CIDR®, Zoetis), más una dosis de 400 UI de gonadotropina coriónica humana (GCH). La fertilidad fue mayor (p< 0,05) (30% de preñez) en borregas inseminadas con semen congelado, comparada al 20% de preñez en las inseminadas con semen frío. Las variables de fertilidad seminal evaluadas demostraron que el semen en el semental katahdin en ambiente tropical fue de buena calidad para su manipulación en la práctica de la inseminación artificial. El grupo racial de los animales utilizados respondieron satisfactoriamente a la sincronización y el semen estuvo dentro de los parámetros establecidos para la especie además toleró la manipulación, en cuanto a la inseminación por laparoscopía, es una técnica de cruzamiento poco diseminada en la región, sin embargo, el estudio desarrollado sugiere mayor investigación para aportar conocimientos suficientes para fortalecer el procedimiento y con ello incrementar la concepción en ovejas servidas

Las ovejas fueron asignadas al azar a seis tratamientos: Grupo I (n=25) control con alimentación tradicional; Grupo II (n=25) control alimentación con subproductos de  hortalizas; Grupo III (n=25) alimentación tradicional y recibieron 125 mg de bST vía SC Cinco días antes del retiro del progestágeno; Grupo IV (n=25) alimentación con subproductos de  hortalizas y recibieron 125 mg de bST vía SC Cinco días antes del retiro de la esponja; Grupo V (n=25) alimentación tradicional recibieron 300 UI de eCG vía SC al momento de retirar la esponja y Grupo VI (n=25) alimentación con subproductos de hortalizas y recibieron 300 UI de eCG vía SC al momento de retirar la esponja. Se comparó la proporción de ovejas que presentaron estro, el % de concepción y la proporción de ovejas con partos múltiples. La respuesta estral fue similar (p>0.05) entre grupos. El porcentaje de concepción fue mayor (p<0.05) en los grupos bST dieta tradicional (80% vs 84%) bST con subproductos de hortalizas respectivamente (p>0.05) comparados con los grupos eCG que fue del 64% en dieta tradicional yb72% con subproductos de hortalizas (p<0.05). La proporción de ovejas con partos múltiples fue mayor en los grupos alimentados con subproductos de hortalizas sobresaliendo los tratados con bST y eCG (1.6 vs 1.7 corderos por parto) respectivamente  (p<0.05). El uso de FGA para la sincronización es efectiva en la presentación de estros. Sin embargo, la aplicación de bST y/o la eCG potencializan este efecto con el aumento de la fertilidad y Prolificidad debido a mayor presencia de folículos viables y por ende más producción de ovocitos. La administración de bST mejora sustancialmente la fertilidad, mientras que la eCG incrementa la Prolificidad.

Se determinó el porcentaje de gestación (PG) para transferencia de embriones (TETF) e  inseminación artificial (IATF) a tiempo fijo, para bovinos de carne, Tamaulipas, bajo condiciones de trópico seco. Se realizaron dos programas de TETF en el norte de Tamaulipas, el primero en el Rancho Puesta de Sol, Burgos, donde se trataron 30 vaquillas con CIDR + benzoato de estradiol (BE) y cipionato de estradiol (ECP) al retiro del CIDR; el segundo programa se realizó en el Rancho La India (Reynosa), donde se sincronizaron 95 vaquillas cruzadas, con el mismo tratamiento. Se realizaron 23 transferencias en Puesta de Sol y 77 transferencias en La India, con embriones de FIV, de la raza Beefmaster, los cuales fueron producidos en el Laboratorio FIV, de la UGRT. Se obtuvieron 8 y 32 gestaciones, para 35 y 42%, respectivamente, para Puesta de Sol y la India, para un total de 40% de gestación total. El programa de IATF se realizó en el Rancho San Isidro (Guémez), utilizando 133 vacas de registro, 50 Brangus Rojo y 88 Charolais, se utilizó el mismo tratamiento que para TETF, además, las vacas paridas y en condición corporal menor de 2.5, se trataron con 330 UI de eCG, al retiro del CIDR, las vacas se inseminaron entre 55 y 60 horas post-retiro del CIDR; las vacas vacías se re-sincronizaron, utilizando el mismo protocolo. Se obtuvo PG de 41%, y 50% en Brangus Rojo y 35% en Charolais; los parciales para PG fueron de 34 y 24% y de 23 y 16%, respectivamente para ambos programas y ambas razas. Las diferencias no fueron significativas en TETF ni para IATF. Se concluye que se pueden implementar programas de TETF e IATF, para mejorar la eficiencia reproductiva de los hatos en Tamaulipas.

The scrotal circumference is one of the main characteristics related to fertility of the bovine male and female. Its study through genetic and genomic tools would help to the discovery of favorable variation and genetic architecture to promote its selection. The aim of this work was to carry out a genome- wide association study using a large microarray of SNPs, to identify variations and candidate genes associated with the studied trait, for which information from 141 Charolais bulls was used. Four markers found, rs110416965, rs110130953, rs43423602 and rs29003417, showed significant association at the genome level. Three of them are found within candidate genes (RBFOX2, TTF2 and CXCL2). This information contributes to the understanding of the genetic architecture of this trait.

La exposición de cerdos a estrés por calor (EC), en comparación con termo neutralidad (TN) afecta la integridad del epitelio intestinal, en parte debido a la sobreproducción de radicales libres. Extractos de hierbas (EH) como Capsicum spp., Pipper nigrum y Zingiber officinales poseen actividad antioxidante. Se evaluó el efecto de adicionar un extracto EH a la dieta en el desempeño productivo de 42 cerdos (27±3 kg) en EC. Los tratamientos fueron: TN-T, cerdos en TN alimentados con dieta testigo; EC-T y EC-EH, cerdos en EC alimentados con dieta testigo sin o con 0.2 % de EH. El experimento consistió de dos periodos; en periodo 1, todos los cerdos tuvieron 8 días de adaptación a la dieta testigo en TN, seguido del periodo experimental de 7 días. La ganancia de peso y consumo de alimento fueron mayores (P <0.05), y la conversión alimenticia tendió a ser mejor (P<0.10) en cerdos EC-EH que en cerdos EC-T. En conclusión, la adición del EH puede contribuir a mejorar algunos parámetros productivos cuando los cerdos están expuestos a EC.

Las vainas y frutos de leguminosas tienen el potencial de utilizarse en la alimentación de rumiantes. El objetivo de la presente investigación fue evaluar las características fermentativas in vitro de la vaina de cubato y fruto de guásimo, para lo cual se incubaron 0.5 g de frutos de guásimo y vainas de cubato con 40 mL de medio de cultivo bajo flujo continuo de CO2 en una incubadora a 39 °C durante 72 h, donde se inocularon con 10 mL de fluido ruminal fresco obtenido de un bovino alimentado con pasto pangola. La producción de biogás se midió a las 0, 2, 4, 6, 8, 10, 12, 24, 48 y 72 h y los estimadores de cinética de producción de biogás se determinaron con el modelo de Gompertz. La producción de metano se midió a las 24, 48 y 72 h de incubación, posteriormente se midio pH del medio y degradación de la materia seca. Las variables se analizaron en un diseño completamente al azar y los valores promedios se compararon con la prueba de Tukey. La producción de biogás de las leguminosas evaluadas mostró diferencia en las primeras 2 h de incubación (p<0.05). Los estimadores de la cinética de fermentación mostraron diferencia en el tiempo lag o eficiencia microbiana (p<0.05), donde el fruto de guásimo fue 17% menor que la vaina de cubato. La producción de metano no presentó diferencias durante el periodo evaluado (p>0.05). El medio de cultivo donde se usó guásimo como sustrato fue 2.2% más ácido que el medio con vaina de cubato como sustrato (p<0.05). La degradación de fruto de guásimo fue 50.3% mayor que la vaina de cubato (p<0.05). La vaina de cubato y fruto de guásimo presentan características fermentativas in vitro deseables para su uso en la alimentación.

En el estudio se evaluó la conducta ingestiva de corderos de pelo finalizados en corral alimentados con rastrojo de hoja de mango. Doce corderos de pelo fueron divididos en dos grupos, el G1 (6 corderos) dieta basal + 20 % de rastrojo de maíz y el G2 (6 corderos) dieta basal + 20 % de rastrojo de hoja seca de mango molida. El periodo de alimentación duró 40 días y cada tercer día se midió la conducta de alimentación por 8 horas continuas: corderos alimentándose, bebiendo, buscan agua, echados, ociosos, rumiando (parados o echados), orinando, defecando (parados o echados), acicalamiento individual, acicalamiento a un compañero y conductas agonistas, así como, el consumo y rechazo de agua. Los datos fueron analizados con el programa estadístico SAS (2021), utilizando un modelo general lineal y se compararon las medias con la prueba de Tukey. Durante el experimento los corderos del G1 tuvieron mayor frecuencia alimentándose y rumiando (echados o parados) que los corderos del G2 (P<0.001). En cambio, los corderos del G2 tuvieron mayor frecuencia echados, ociosos y conductas agonistas que los corderos del G1 (P<0.001). Por otro lado, los corderos del G1 tuvieron mayor consumo de agua durante el experimento que los corderos del G2 (P<0.01). Se concluye que los corderos alimentados con rastrojo de maíz tuvieron mayor frecuencia de alimentación, rumia y consumo de agua.

Despite the well-known influence of social determinants on access to health services, it is still being determined whether there are differences in the user profile regarding access to guidelines and prescriptions for medicinal plants and herbal medicines in Brazil. Given this context, the present study aimed to investigate the prevalence of professional guidelines and prescriptions on phytotherapy and associated factors among Brazilian practice users. The research is cross-sectional, analytical, and with a quantitative approach. In total, 1,396 individuals were questioned about access to guidance on phytotherapy, and of these, 664 (47.6%) received such guidance. Likewise, 1,421 participants were asked about the prescription for this use, among which 510 (35.9%) received a prescription for medicinal plants and/or herbal medicines. Phytotherapy guidelines and prescriptions in Brazil proved to be infrequent. There must be professional training, investments in continuing education, and readjustment of public policies among health professionals to encourage the use of herbal medicines.
