Resumo Várias razões podem estar subjacentes ao aumento dramático da diabetes mellitus tipo 2. Um desses motivos é a base genética e variações. Os polimorfismos do receptor da vitamina D estão associados a diferentes doenças, como artrite reumatoide e diabetes. O objetivo deste estudo é investigar a possível associação de duas mutações identificadas ApaI (rs7975232) e TaqI (rs731236). Oitenta e nove indivíduos saudáveis e 56 pacientes com diabetes tipo 2 (T2D) foram investigados usando a técnica RFLP para genotipagem e haplotipagem também. A distribuição dos genótipos Apal não foi estatisticamente significativa entre o controle (P = 0,65), bem como para os pacientes diabéticos (P = 0,58). Para as frequências do alelo Taql, o alelo T foi de 0,61, onde o alelo G foi de 0,39. A distribuição de frequência dos genótipos Taql não foi estatisticamente significativa entre o controle (P = 0,26), bem como os pacientes diabéticos (P = 0,17). O risco relativo do alelo T do gene Apa1 é 1,28 e a razão de chances do mesmo alelo é 1,53, enquanto ambas as estimativas foram < 1,0 do alelo G. Da mesma forma, com o gene Taq1, os valores de risco relativo e razão de chances para o alelo T são 1,09 e 1,27, respectivamente, e ambas as estimativas do alelo C foram de 0,86 para o risco relativo e 0,79 para o odds ratio. O desequilíbrio de ligação par a par entre os dois SNPs Taq1 / apa1 foi estatisticamente significativo no grupo de controle (D = 0,218, D' = 0,925 e valor P < 0,001) e dados semelhantes em grupos diabéticos (D = 0,2, D' = 0,875 e valor P < 0,001). Esses dados sugerem que o alelo T de ambos os genes Apa1 e Taq1 está associado ao aumento do risco de diabetes tipo 2. Achamos que precisamos de um número maior de voluntários para chegar a uma conclusão mais precisa.

Abstract Several reasons may underlie the dramatic increase in type2 diabetes mellitus. One of these reasons is the genetic basis and variations. Vitamin D receptor polymorphisms are associated with different diseases such as rheumatoid arthritis and diabetes. The aim of this study is to investigate the possible association of two identified mutations ApaI (rs7975232) and TaqI (rs731236). Eighty-nine healthy individuals and Fifty-six Type 2 Diabetic (T2D) patients were investigated using RFLP technique for genotyping and haplotyping as well. The distribution of Apal genotypes was not statistically significant among the control (P=0.65) as well as for diabetic patients (P=0.58). For Taql allele frequencies of T allele was 0.61 where of G allele was 0.39. The frequency distribution of Taql genotypes was not statistically significant among the control (P=0.26) as well as diabetic patients (P=0.17). Relative risk of the allele T of Apa1 gene is 1.28 and the odds ratio of the same allele is 1.53, while both estimates were < 1.0 of the allele G. Similarly, with the Taq1 gene the relative risk and the odds ratio values for the allele T are 1.09 and 1.27 respectively and both estimates of the allele C were 0.86 for the relative risk and 0.79 for the odds ratio. The pairwise linkage disequilibrium between the two SNPs Taq1/apa1 was statistically significant in control group (D = 0.218, D' = 0.925 and P value < 0.001) and similar data in diabetic groups (D = 0.2, D' = 0.875 and P value < 0.001). These data suggest that the T allele of both genes Apa1 and Taq1 is associated with the increased risk of type 2 diabetes. We think that we need a larger number of volunteers to reach a more accurate conclusion.

Resumo O setor florestal brasileiro se destaca pela tecnologia, práticas de manejo florestal, responsabilidade social e ambiental e, principalmente, alta produtividade, mas pragas exóticas podem reduzir isto. O parasitoide Psyllaephagus bliteus (Riek, 1962) (Hymenoptera: Encyrtidae), percevejos predadores e fungos entomopatogênicos como Beauveria bassiana e Metarhizium anisopliae são inimigos naturais usados no controle biológico do psilídeo-de-concha do eucalipto Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Aphalaridae), praga em plantios de eucalipto. A utilização de fungos entomopatogênicos contra pragas exóticas vem aumentando no setor florestal e a prospecção e identificação de isolados fúngicos é importante para o manejo integrado de pragas. O objetivo deste estudo foi o isolamento e identificação molecular de Cordyceps spp. e avaliar a patogenicidade dos isolados de Cordyceps javanica (LCBPF 11) e Cordyceps fumosorosea (LCBPF 12 e LCBPF 63), obtidos de adultos de Bemisia tabaci Gennadius (Hemiptera: Aleyrodidae), ao psilídeo-de-concha G. brimblecombei. Os fungos foram isolados de adultos de B. tabaci encontrados em culturas de soja e tomate e identificados molecularmente. Os conídios foram suspensos em solução com Tween 80 (0,1%) na concentração de 1,0 x 108 conídios/mL e pulverizados sobre dez ninfas de G. brimblecombei por folha de Eucalyptus cortada e colocada sobre gel hidrorretentor no interior de placas de Petri por repetição. O número de insetos mortos foi quantificado, diariamente, por sete dias e transferidos para câmaras úmidas. Cordyceps javanica (LCBPF 11) e C. fumosorosea (LCBPF 12 e LCBPF 63) foram identificados por análise molecular e todos os isolados foram patogênicos para os insetos. Isto indica serem importantes para o manejo de G. brimblecombei e confirma relatos de que, normalmente, fungos causam maiores mortalidades em insetos da mesma ordem daquela da qual foram isolados.

Abstract The Brazilian forestry sector stands out for its technology, forestry management practices, social and environmental responsibility and, mainly, for its high productivity and exotic pests can reduce it. The red gum lerp psyllid Glycaspis brimblecombei (Moore, 1964) (Hemiptera: Aphalaridae) is an important pest in Eucalyptus plantations. The parasitoid Psyllaephagus bliteus (Riek, 1962) (Hymenoptera: Encyrtidae), predatory bugs and entomopathogenic fungi such as Beauveria bassiana and Metarhizium anisopliae are the natural enemies and used in the biological control of the red gum lerp psyllid. The use of entomopathogenic fungi against exotic pests is increasing in the forestry sector and the prospecting and identification of fungus isolates is important for integrated pest management. The objective of this work was the isolation and molecular identification of Cordyceps spp. And to evaluate the pathogenicity of isolates, obtained from Bemisia tabaci (Gennadius, 1889) (Hemiptera: Aleyrodidae) adults, against to the red gum lerp psyllid G. brimblecombei. The fungi were isolated from B. tabaci adults found in soybean and tomato crops and molecularly identified. The conidia obtained were suspended in solution with Tween 80 (0.1%) at a concentration of 1.0 × 108 conidia/mL and sprayed on ten G. brimblecombei nymphs per Eucalyptus leaf cut and placed on a hydroretentive gel inside per Petri dishes as a replication. The number of dead insects was quantified, daily, for seven days, and transferred to humid chambers. Cordyceps javanica (LCBPF 11) and C. fumosorosea (LCBPF 12 and LCBPF 63) were identified with a molecular analysis and all isolates were pathogenic to the insects and indicates that they could be used to manage G. brimblecombei and adds to reports that, normally, fungi cause greater mortality on insects of the same order as that from which they were isolated.

Resumo Introdução: A cistogastrostomia/duodenostomia pancreática guiada por ecoendoscopia (EUS) é atualmente aceite para a abordagem dos pseudoquistos pancreáticos sintomáticos através da inserção de dois ou mais stents duplo pigtail (DP). A evidência é escassa relativamente à eficácia da utilização de apenas um stent duplo pigtail de grande calibre, com o objetivo de diminuir o tempo, as complicações e os dispositivos utilizados no procedimento. Objetivo: Avaliar os resultados técnicos e clínicos do uso de stent duplo pigtail único de grande calibre na drenagem de pseudoquistos pancreáticos guiada por ecoendoscopia. Metodologia: Estudo prospetivo multicêntrico incluindo 57 doentes (dos quais 35 com pseudoquistos pancreáticos sintomáticos). Foram excluídos pacientes com quistos multiseptados (7 casos), com necrose >30% (8 casos), com ascite (4 casos) e comorbidades major (3 casos). O follow-up foi ao 1 mês e 6 meses após a colocação do stent para avaliar a resolução completa ou diminuição no tamanhos dos pseudoquistos com melhoria sintomática. Resultados: Dos 57 doentes, 35 (19 mulheres/16 homens, idade média 40 anos) com pseudoquistos pancreáticos sintomáticos foram submetidos a drenagem guiada por EUS. Todos os stents utilizados foram stents DP plásticos com 10 Fr. A duração mediana do procedimento foi de 16 minutos. O sucesso técnico foi alcançado em todos os casos. Ocorreu sucesso clínico em 32 doentes (91,4%), sem reacumulação no seguimento. Eventos adversos menores ocorreram em 3 doentes (8,6%), incluindo dor abdominal pós-procedimento (1) e febre (2). Conclusão: Os resultados sugerem que a utilização de stent pigtail único de grande calibre para cistogastrostomia guiada por EUS é segura e eficaz, com tempo de procedimento curto e reduzindo o risco da inserção de outro(s) stent(s).

Abstract Introduction: Endoscopic ultrasound (EUS)-guided pancreatic cysto-gastrostomy/duodenostomy is the current accepted practice for management of symptomatic pancreatic pseudocysts with insertion of two or more double-pig-tail (DP) stents. There is no much work on the efficacy of using a single wide-caliber DP stent, aiming to decrease the time, complications, and accessories used in the procedure. Aim of the Work: The aim of this study was to assess technical and clinical outcomes of using a single wide-caliber DP stent in EUSguided pancreatic pseudocyst drainage. Methodology: This multicenter prospective study included 57 patients, from which the 35 patients with symptomatic pancreatic pseudocysts enrolled. Patients with cysts with mul-tiple septations (7 cases) or cyst with >30% necrosis (8 cases) of the cyst content and patients with generalized ascites (4 cases) or patients with major comorbidities (3 cases) were excluded. Patients were followed up within 1 month and 6 months after stent placement to assess complete resolution or a decrease in the sizes of cysts with clinical symptomatic improvement. Results: From 57 patients, 35 patients (19 females/16 males, median age 40 years) with a symptomatic pancreatic pseudocyst were referred for EUS-guided drainage. All used stents were 10 Fr DP plastic stents. The median duration of the whole procedure was 16 min. Technical success was achieved in all cases. Clinical success was encountered in 32 patients (91.4%) without re-accumulation on follow-up. Minor adverse events were encountered in 3 patients (8.6%) including post-procedure abdominal pain (1 case) and fever (2 cases). Conclusion: We suggest that using a wide-caliber single-pigtail stent for EUS-guided cystogastrostomy is safe and effective with short procedure time, with reduced risks from the insertion of another stent(s).

Increasingly high levels of multidrug-resistant (MDR) pathogens have necessitated the discovery of novel bioactive compounds. For this reason, two actinomycetes strains, Streptomyces griseorubens and Streptomyces rochei, were isolated for the first time from the black sand shores of Kafr El Sheikh in Egypt, which is home to several large fish farms. Isolates were identified via phenotypic, biochemical and 16S rRNA sequence protocols. Both strains exhibited powerful antimicrobial activity against three serious MDR pathogens: Bacillus subtilis, Salmonella enteritidis and Pseudomonas aeruginosa. The bioactive compounds of isolates' filtrates were identified using gas chromatography-mass spectroscopy (GC-MS). For S. griseorubens, the detectable antibacterial compounds were hexanoic acid, 2-ethyl-, 2-ethylhexyl ester, n-Decane, hexadecanoic acid methyl ester, benzene acetic acid, ricinolic acid, and ethylparaben, while S. rochei secretes heptadecane, 2,6-dimethyl-, benzene acetic acid, dibutyl phthalate, octacosane, hexacosane, and vitamin A aldehyde. These results strongly encourage the use of these eco-friendly isolates as a biocontrol against MDR pathogens that attack fish farms. SIGNIFICANCE: Streptomyces spp. act as strong weapons for fighting multidrug resistance in pathogenic bacteria - one of the most important current threats to public health. They are additionally regarded as eco-friendly organisms that can be used as a biocontrol agent against infections that endanger fish farms

ABSTRACT The present work aims to evaluate anticancer performance of Cassia alata methanolic leaf extracts (CMLE) in ethyl carbamate-stimulated lung adenocarcinoma (LAD) in differentiation to the function of Cisplatin (CIPL). Rats were divided into four groups: (1) control (CONT), (2) lung-adenocarcinoma (LAD) injected intra-peritoneally with 1g/kg ethyl carbamate once weekly for a month, (3) LAD+CMLE administered 500 mg/kg CMLE orally for the last two months of the experiment, and (4) LAD+CIPL treated group, injected 2.5 mg/kg Cisplatin intraperitoneally once weekly for the last two months of the experiment. Light and electron microscopic examinations revealed adenocarcinoma development in terminal bronchiole besides some histopathological changes in the LAD group such as atypical, exaggerated collagen fibers, increment of mucinous content, and increasing of PCNA positive immunoreactivity whereas electron microscopy investigation exposed that papillary adenocarcinoma originated from Clara cells in the LAD group. The LAD+CMLE treated group showed no tumor masses and nearly all with normal lung histology. It also recovered the normal ultrastructure of bronchiolar Clara cells. CMLE treatment offers a new alternative cure with less toxicity than Cisplatin for lung cancer therapy. Hence, CMLE would be employed as a novel supply of anti-cancer compounds combating lung cancer.

RESUMO O presente trabalho tem como objetivo avaliar o desempenho anticâncer dos extratos metanólicos das folhas de Cassia alata (CMLE) em adenocarcinoma pulmonar estimulado por carbamato de etila (LAD) em diferenciação com a função da cisplatina (CIPL). Os ratos foram divididos em quatro grupos: (1) controle (CONT), (2) adenocarcinoma de pulmão (LAD) injetado intraperitonealmente com 1g/kg de carbamato de etila uma vez por semana durante um mês, (3) LAD+CMLE administrado 500 mg/kg de CMLE por via oral nos últimos dois meses do experimento e (4) grupo tratado com LAD+CIPL, injetado 2,5 mg/kg de cisplatina intraperitonealmente uma vez por semana nos últimos dois meses do experimento. Os exames de microscopia de luz e eletrônica revelaram o desenvolvimento de adenocarcinoma no bronquíolo terminal, além de algumas alterações histopatológicas no grupo LAD, como fibras de colágeno atípicas exageradas, aumento do conteúdo mucinoso e aumento da imunorreatividade positiva para PCNA, enquanto a investigação de microscopia eletrônica revelou que o adenocarcinoma papilar se originou das células Clara no grupo LAD. O grupo tratado com LAD+CMLE não apresentou massas tumorais e quase apresentou histologia pulmonar normal. Ele também recuperou a ultraestrutura normal das células de Clara bronquiolares. O tratamento com CMLE oferece uma nova alternativa de cura com menos toxicidade do que a cisplatina para a terapia do câncer de pulmão. Portanto, o CMLE seria empregado como um novo suprimento de compostos anticancerígenos para combater o câncer de pulmão.

Abstract Carnation (Dianthus caryophyllus ‘Servantes’) is a popular and economically cut flower widely used in the florist industry. However, post-harvest senescence occurs in a few days and limits the cut carnation flowers’ commercialization. Therefore, this research was performed to investigate the impact of essential oils such as tea tree oil (TTO), pumpkin seed oil (PSO), Moringa seed essential oils (MEO), and Eucalyptus oils (EEO), as eco-friendly preservative solutions to enhance the quality and longevity of carnation flowers. Carnation cut flowers were submitted to different concentrations (250 and 500 mg L-1) of each essential oil used in the vase solution and the experiments were carried out as a completely randomized design in three replicates. The findings revealed that the longest vase life and the maximum total water solution uptake in cut carnation were achieved when treated with either TTO or PSO oil at 500 mg L-1 in solution preservative as compared to the control (distilled water). While the highest relative fresh weight was observed at 500 mg L-1 PSO, the highest chlorophyll a, b, total carotenoids, total sugar, total phenolic content in leaves, anthocyanin content, and enzyme activity in petals at 500 mg L-1 TTO and PSO. Additionally, all treatments of selected oils have positively declined the bacteria activity compared to control. Also, the lowest bacteria growth on third day with 500 mg L-1 TTO and PSO. However, observing a prim state of xylem vessels with TTO 500 mg L-1and PSO 500 mg L-1, comparable with distilled water, the application of essential oil in this study as a natural preservative in preservative solution as an alternative to chemicals could be of environmental value and great economic.

Resumo O cravo (Dianthus caryophyllus ‘Servantes’) é uma flor e corte popular e economicamente viável, amplamente utilizada na indústria florística. Apesar disso, a senescência pós-colheita ocorre em poucos dias, sendo um problema limitante na comercialização de flores de cravos cortadas. Assim, realizou-se a pesquisa para investigar o impacto de óleos essenciais como o óleo de árvore de chá (TTO), óleo de semente de abóbora (PSO), óleos essenciais de semente de Moringa (MEO), e óleos de Eucalipto (EEO), como soluções conservantes ecologicamente corretas para melhorar a qualidade e a longevidade das flores de cravo. As flores de cravo cortadas foram submetidas a diferentes concentrações (250 e 500 mg L-1) de todos os óleos essenciais utilizados na solução de vaso. Os resultados revelaram que a maior vida útil de vaso e a máxima absorção total da solução pelo cravo cortado ocorreu nos tratamentos com óleo TTO ou PSO a 500 mg L-1 na solução conservante em comparação com o controle (água destilada). Enquanto o maior peso relativo fresco indicado com 500 mg L-1 PSO, a maiores valores de clorofila a e b, carotenóides totais, açúcares totais, conteúdo fenólico total nas folhas, conteúdo de antocianina e atividade enzimática em pétalas tratadas com 500 mg L-1 de (TTO) e (PSO). Além disso, todos os tratamentos de óleos atuaram diminuindo a atividade bacteriana em comparação com o controle. Também, o menor crescimento bacteriano ocorreu no terceiro dia com o uso 500 mg de L-1 TTO e PSO. Entretanto, observando um estado primário de vasos de xilema de hastes tratadas com 500 mg L-1 de TTO e 500 mg L-1 de PSO, comparando com água destilada, a aplicação do óleo essencial neste estudo como conservante natural em solução conservante como alternativa aos produtos químicos pode ser de grande valor ambiental e econômico.

Abstract Background: Prediabetic patients are at increased risk for cardiovascular diseases and the development of microvascular and macrovascular complications. Intermittent fasting (IF) and low-carbohydrate diet (LCD) are promising dietary plans. Objectives: Our aims to analyze the benefits of IF combined with LCD on microvascular and macrovascular outcomes in prediabetic patients. Methods: The study included 485 prediabetic patients with no history of cardiovascular diseases divided into group I: (n = 240 patients) who underwent IF (16 h IF 3-4 days per week) combined with LCD (<130 g of carbohydrate per day), and group II: (n = 245 patients) with ad libitum calorie intake. The two groups were followed-up for two years for assessment of micro and macrovascular complications. A p-value < 0.05 was considered statistically significant. Result: There was a significant reduction in body weight, body mass index, waist circumference, body fat percentage and glycated hemoglobin in group I. The incidence of progression from prediabetes to diabetes was significantly lower in group I (2.1% vs. 6.9% in group II, p = 0.010). In addition, a significant increase in the incidence of microvascular and macrovascular complications was observed in group II, including retinopathy, neuropathy and unstable angina. Multivariate regression analysis revealed that increased body weight, fasting glucose, glycated hemoglobin and low-density lipoprotein were independent risk factors impacting microvascular and macrovascular outcomes. Conclusions: In prediabetic patients, IF, combined with LCD, was associated with lower progression to diabetes mellitus and lower incidence of microvascular and macrovascular complications.

Resumo Fundamentos: Pacientes pré-diabéticos têm alto risco de doenças cardiovasculares e complicações microvasculares e macrovasculares. O Jejum Intermitente (JI) e a dieta restrita em carboidratos (dieta low-carb, DLC) são estratégias dietéticas promissoras nesse grupo. Objetivos: Analisar os benefícios da combinação do JI com DLC sobre desfechos microvasculares e macrovasculares em pacientes pré-diabéticos. Métodos: O estudo incluiu 485 pacientes pré-diabéticos sem história de doença cardiovascular. Os pacientes foram divididos em dois grupos: grupo I (n = 240) submetidos ao JI (16 horas de JI, F 3-4 dias por semana) combinado com DLC (<130 g de carboidratos por dia), e grupo II (n = 245) que consumiram alimentos à vontade (grupo controle). Os dois grupos foram acompanhados por dois anos para avaliação de complicações macrovasculares e microvasculares. Um valor p < 0,05 foi considerado estatisticamente significativo. Resultados: Houve uma redução significativa no peso corporal, índice de massa corporal, porcentagem de gordura corporal e hemoglobina glicada no grupo I. A incidência de progressão de pré-diabetes para diabetes foi significativamente menor no grupo I (2,1%) que no grupo II (6,9%) (p = 0,010). Ainda, um aumento significativo na incidência de complicações microvasculares e macrovasculares foi observado no grupo II, incluindo retinopatia, neuropatia e angina instável. A análise de regressão multivariada revelou que peso corporal aumentado, e níveis elevados de glicemia de jejum, hemoglobina glicada e lipoproteína de baixa densidade foram fatores de risco independentes de desfechos microvasculares e macrovasculares. Conclusões: Em pacientes pré-diabéticos, o JI, combinado com DLC, associou-se com menor progressão para diabetes mellitus e menor incidência de complicações microvasculares e macrovasculares.

Abstract Salinity is one of abiotic stress that affects plant growth and production. The objective of this study was to investigate the effect of salinity and vermicompost on morphology and physiology parameters of Calliandra haematocephala. The experiment was carried out with salinity treatments at 1000, 2000 3000 ppm in addition to the control (tap water, 280 ppm), vermicompost treatments at 5%, 10%, 15%, and 20% in addition to the control. The results indicated that increasing level of salinity resulted in reduction in vegetative growth and flowering parameters (plant height, number of branches/plant, stem diameter, root length, fresh and dry weights of leaves and roots/plant, number of flowers /plant, as well as fresh and dry weights of flowers /plant), total chlorophylls, total carbohydrates, K+%, Ca2+%, and K+/Na+ ratio, while increased proline, Na+ and Cl−% in the plants. Catalase (CAT), superoxide dismutase (SOD), Ascorbate peroxidase (APX) enzyme activities significantly increased with elevating salinity level from 0 to 3000 ppm. Application of vermicompost with any concentration had a positive effect on vegetative growth and flowering parameters, total chlorophylls, total carbohydrates, nutrient uptake, K+/Na+ ratio, proline content, enzyme activities and reducing accumulation of Na+ and Cl−% toxic ions in leaves. Based on the results, application of vermicompost at 20% recommended for alleviating the harmful efects of salinity on Calliandra haematocephala plants irrigated with saline water at concentration up to 3000 ppm.

Resumo A salinidade é um estresse abiótico que afeta o crescimento e a produção das plantas. O objetivo deste estudo foi investigar o efeito do vermicomposto e dos efeitos da salinidade sobre os parâmetros morfológicos e fisiológicos de Calliandra haematocephala. O experimento foi realizado com tratamentos de vermicompostagem a 5%, 10%, 15% e 20% além do controle, tratamentos de salinidade a 1000, 2000 3000 ppm além do controle (água da torneira, 280 ppm). Os resultados indicaram que o aumento do nível de salinidade resultou em redução no crescimento vegetativo e nos parâmetros de floração (altura da planta, número de ramos/planta, diâmetro do caule, comprimento da raiz, massa fresca e seca das folhas, raízes/planta, número de flores/planta, bem como pesos frescos e secos de flores/planta), clorofilas totais, carboidratos totais, K+%, Ca2+% % e relação K+/Na+, enquanto aumentou prolina, Na+ e Cl−% nas plantas. As atividades das enzimas catalase (CAT), superóxido dismutase (SOD), ascorbato peroxidase (APX) aumentaram significativamente com a elevação do nível de salinidade de 0 a 3000 ppm. A aplicação de vermicomposto em qualquer concentração teve efeito positivo sobre o crescimento vegetativo e parâmetros de floração, clorofilas totais, carboidratos totais, absorção de nutrientes, relação K+/Na+, teor de prolina, atividades enzimáticas e redução do acúmulo de íons tóxicos Na+ e Cl−% nas folhas. Com base nos resultados, a aplicação de vermicomposto a 20% é recomendada para aliviar os efeitos nocivos da salinidade em plantas de Calliandra haematocephala irrigadas com água salina em concentração de até 3000 ppm.

ABSTRACT The number of therapeutic interventions supported by the use of digital resources is increasing every day as a way to facilitate access to any type of health care. A systematic review was carried out with the aim of analyzing the effectiveness (functional status, pain intensity and adherence to treatment) of the physiotherapy intervention, supported by digital resources, compared to conventional physiotherapy in adult patients with back pain. This study consulted the scientific databases such as PubMed, Virtual Health Library, Cochrane, Evidence-Based Physiotherapy Database, Science Direct, Scopus, Episteminikos, and Google Scholar. The initial selection of the studies, the exhaustive evaluation of the full articles and the extraction of the characteristics necessary for the investigation were carried out by the six research fellows and reviewed by two independent reviewers. Twelve articles were included (10 clinical trials and two cohort studies). The results of the systematic review support the use of available digital resources for the management of low back pain, with an important relationship with the reduction of pain levels and the improvement in functionality. It is necessary to carry out more high-quality studies to demonstrate these results, since the criteria for the intervention are yet to be determined.

RESUMEN El número de intervenciones terapéuticas apoyadas en el uso de los recursos digitales aumenta cada día como vía para facilitar el acceso a cualquier tipo de atención sanitaria. Se realizó una revisión sistemática con el objetivo de analizar la efectividad (estado funcional, la intensidad del dolor y la adherencia al tratamiento) de la intervención de fisioterapia, apoyada en recursos digitales, frente a la fisioterapia convencional en pacientes adultos con dolor de espalda. Este estudio consultó las bases de datos científicas: PubMed, Biblioteca Virtual en Salud, Cochrane, Base de datos de Fisioterapia basada en la evidencia, Science Direct, Scopus, Episteminikos y Google Académico. La selección inicial de los estudios, la evaluación exhaustiva de los artículos completos y la extracción de las características necesarias para la investigación fueron realizadas por los seis investigadores y revisadas por dos revisores independientes. Se incluyeron 12 artículos (10 ensayos clínicos y dos estudios de cohorte). Los resultados de la revisión sistemática soportan el uso de los recursos digitales disponibles para el manejo de dolor de espalda baja, con una importante relación con la reducción de los niveles de dolor y la mejora en la funcionalidad. Es necesario realizar más estudios de alta calidad para evidenciar estos resultados, pues están por determinarse los criterios de la intervención.

RESUMO O estudo tematiza os desafios postos à educação dada em um cenário em que o modo de operar das mídias digitais põe dificuldades ao estabelecimento de uma forma de vida democrática e à configuração de um mundo humano comum. Contextualiza o atual cenário sociopolítico à luz dos modos de apropriação, de crítica e de abandono da racionalidade, destacando consequências práticas vinculadas a determinadas posições pós-modernas. Em um esforço de recuperar ‘energias utópicas’ presentes no ideário da modernidade iluminista, tanto na educação como na política, aposta em uma razão ancorada na intersubjetividade linguística como forma de legitimação das ordens sociais e políticas e como sustentação e orientação dos processos de formação das novas gerações. comum apropriação racionalidade pósmodernas. pósmodernas pós modernas. modernas pós-modernas energias utópicas iluminista política gerações

ABSTRACT The study addresses the challenges posed to education in a scenario where the operating mode of digital media presents difficulties in establishing a democratic way of life and shaping a common human world. It contextualizes the current sociopolitical landscape in light of modes of appropriation, criticism, and abandonment of rationality, highlighting practical consequences linked to certain postmodern positions. In an effort to recover ‘utopian energies’ present in the ideals of enlightenment modernity, both in education and politics, it relies on a reason anchored in linguistic intersubjectivity as a means of legitimizing social and political orders and as a foundation and guiding force in the process of educating new generations. world appropriation criticism rationality positions utopian energies modernity politics generations

Abstract Due to the absence of previous works that address the multisemiotic nature of the didactic material of Spanish as a foreign language (SFL), this paper aims to provide a complete overview of the use of the multimodal elements incorporated in the classroom texts. In this sense, the present study aims to determine the semiotic systems that shape the texts of four courses taught in the context of a student exchange program in Valparaíso Chile specialized in teaching of Spanish as a foreign language. To achieve this goal, a qualitative study with a descriptive and exploratory scope has been conducted and 64 texts of History and Literature courses have been analyzed to determine the multimodal artifacts. The analysis of materials was complemented by semi-structured interviews with the four professors in charge of the courses of both disciplines. Also, the reasons behind the absence or presence of multimodal support in this material were discussed in depth. The data was interpreted through a content analysis carried out in the Nvivo 12 program. The results of the analysis show a predominance of the verbal semiotic system in the learning material basically because teaching staff tended to discard multimodal elements.

Resumen Ante la ausencia de trabajos previos que abordan los elementos multisemióticos en el material didáctico de los cursos de español como lengua extranjera (ELE), en este trabajo se pretende ofrecer una imagen completa sobre el uso del elemento multimodal en los textos didácticos. En este orden de ideas, el presente trabajo tiene como objetivo determinar los sistemas semióticos que conforman los textos de cuatro cursos que se dictan en el contexto de un programa de intercambio estudiantil en la V Región en Chile especializado en la enseñanza de español como lengua extranjera. Para lograr este objetivo se adopta un enfoque cualitativo con alcance descriptivo y exploratorio y se realiza un análisis de los artefactos multimodales que conforman 64 textos de cursos de Historia y Literatura. El análisis de materiales se complementa con entrevistas semiestructuradas con los cuatro docentes a cargo de los cursos de ambas disciplinas en donde se profundiza sobre las razones de ausencia o presencia de la multimodalidad en este material. Los datos se interpretan mediante un análisis de contenido realizado en el programa Nvivo 12. Los resultados del análisis muestran una predominancia del sistema semiótico verbal en el material didáctico que se debe a descartarlos por parte del profesorado.

Abstract Introduction Epistaxis is a common presentation among children. Objective To investigate the suitability of a simple tool of assessment for patients with epistaxis that could guide in subgrouping those with possible bleeding tendencies who may need further assessment. Methods Children who presented to a tertiary outpatient clinic with epistaxis of an unknown cause were recruited. They underwent thorough clinical assessment and answered the pediatric bleeding questionnaire and the epistaxis severity score. All patients underwent complete blood count as well as coagulation profile, and confirmatory diagnostic tests were performed as needed. Results Among the 30,043 patients who presented to the outpatient clinic over a year, 100 children had epistaxis, with an estimated annual frequency of 1 in 300. A total of 84% of the patients were younger than 12, and nearly half of these were younger than 6 years. Seventy-six patients had recurrent epistaxis, and 12 had systemic comorbidities. A significant higher percentage of patients presented with epistaxis in the hot months of the year. A total of 90% of the patients presented anterior bleeding, and the majority were treated with nasal compression only. Forty-three patients presented with epistaxis only; 37 of them were diagnosed as idiopathic epistaxis, and 6 had local causes. Fifty-seven patients presented with other bleeding manifestations, 47 of whom had a definite bleeding disorder and the other 10 had undiagnosed bleeding tendency. Those with other bleeding manifestations showed a higher frequency of positive family history of epistaxis; of being referred from a primary care physician; of having alarming low platelet count, and of presenting less seasonal variability. A bleeding score ≥ 2 showed significant value in suspecting an underlying systemic pathology as a cause of epistaxis. Conclusion The pediatric bleeding questionnaire is a useful and simple tool in the identification of pediatric patients who need further diagnostic testing to detect any underlying bleeding tendency.

Resumo Gazania (L.) é uma planta ornamental silvestre que possui arquiteturas especiais. É um pequeno gênero de 16 espécies, pertencente à família Asteraceae (Anteriormente: Compositae). É uma erva perene de baixo crescimento, cresce em tufos e também pode formar tapetes densos que cobrem grandes áreas. Gazania tem vários gêneros e espécies com cores de múltiplas pétalas. A pigmentação da clorofila foi medida nas folhas e pétalas desses espécimes que apresentam alta diferença significativa. Genômica é o estudo de genomas e pode ser usada para conduzir pesquisas sobre a evolução do genoma, variações genômicas, regulação gênica e mecanismos biológicos importantes, usando informações detalhadas da sequência do genoma. A diversidade das plantas ornamentais, assim como o lento progresso da pesquisa do genoma de plantas ornamentais há muito tempo. O RAPD-PCR foi aplicado no presente estudo para estimar a variação genética nessas amostras que resultou em uma porcentagem total de polimorfismo de 42,36%. Este percentual de polimorfismo leva à variação nas vias fisiológicas essenciais em Gazania spp e reflete na cor multivariada das pétalas.

Abstract Gazania (L.) is one of wild ornamental plant which has special architectures. It is a small genus of 16 species, belonging to the family Asteraceae (Formerly: Compositae). It is low-growing perennial herb, grow in clumps and can also form dense carpets covering large areas. Gazania has multiple genera and species with mutli-petals colors. The chlorophyll pigmentation was measured in leaves and petals of these specimens which show high significant difference. Genomics is the study of genomes, and it can be used to conduct research on genome evolution, genomic variations, gene regulation, and important biological mechanisms using detailed genome sequence information. The diversity of ornamental plants, as well as the slow progress of genome research on ornamental plants for a long time. RAPD-PCR was applied in the present study to estimate the genetic variation in these samples which resulted in a total polymorphism percentage of 42.36%. This polymorphism percentage lead to the variation in essential physiological pathways in Gazania spp and reflected on the multivariate petals color.

Abstract Background: Vitiligo is an acquired and progressive mucocutaneous disease resulting from the loss of active epidermal melanocytes. Metabolic syndrome (MetS) affects about 25% of the world’s population and is linked to inflammatory skin diseases including vitiligo. Fatty AcidBinding Protein 4 (FABP4) is an intracellular lipid chaperone. FABP4 is closely associated with MetS. Objectives: To evaluate the serum level of FABP4 in vitiligo patients and its relation to MetS in the investigated cases. Methods: This case control study was conducted on 45 patients having non segmental vitiligo and 45 matched controls. Their lipid profile, blood glucose and serum FABP4 levels were measured. Results: There were significant elevations in FABP4 (p < 0.001), cholesterol (p < 0.001), triglycerides (p = 0.005), and glucose (fasting [p = 0.001] and 2 hours post prandial [p < 0.001]) levels in patients in comparison with controls. MetS was significantly more prevalent among vitiligo patients (p < 0.001) and associated with high FABP4 serum levels (p = 0.037). In vitiligo patients, there were significant positive correlations between FABP4 serum levels and triglycerides (p = 0.047), cholesterol (p = 0.001) and LDL (p = 0.001) levels and negative correlation regarding HDL level (p = 0.009). FABP4 level was a significantly good diagnostic test for early detection of vitiligo (p < 0.001). Study limitations: The small number of studied subjects. Conclusions: FABP4 may play an active role in the disease process of vitiligo that could be mediated through associated dyslipidemia and hyperglycemia. FABP4 may be a marker of vitiligo helping in its early diagnosis, but it does not appear to be useful for determining vitiligo severity, activity or associated MetS.

Abstract Some plants of the genus Pulicaria have been used in traditional medicines for treating back pain and inflammation. They possess various bioactivities such as antipyretic, analgesic, and hepatoprotective. This study aimed to investigate the potential analgesic, antipyretic, anti- inflammatory, and hepatoprotective activities of Pulicaria crispa (P. crispa) extract (PCE). Analgesic activity was evaluated using the hot plate and acetic acid-induced writhing tests. Antipyretic and anti-inflammatory activities were evaluated using rectal temperature and carrageenan-induced hind paw edema methods, respectively. CCl4-intoxication was used for hepatoprotective activity. Also, liver histopathology was assessed. PCE, at 500 mg/kg, exhibited significant analgesic, antipyretic, and anti-inflammatory effects. The increased serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), and bilirubin of CCl4-exposed rats reflects their liver injury. PCE significantly decreased the elevated liver markers. The hepatoprotective effect of PCE was confirmed, as it successfully reversed the altered levels of total protein, malondialdehyde (MDA), and non-protein sulfhydryls (NP-SH) in the liver tissues of CCl4-exposed rats. Histopathological studies confirmed the hepatoprotective nature of PCE. Pretreatment of rats with PCE reduced the severity of CCl4-induced liver damage. These findings concluded that PCE possesses analgesic, antipyretic, anti-inflammatory, and hepatoprotective activities.
