Effect edible antimicrobial coating in the white blush and anaerobic psychrotrophs baby carrots

[POR] Objetivou-se avaliar a qualidade visual e microbiológica de minicenouras submetidas a diferentes concentrações de amido de milho em suspensão utilizado para revestimento comestível. Cenouras cv. Esplanada colhidas aos 90 dias, minimamente processadas na forma de minicenouras, foram imersas em suspensão contendo 2, 3 ou 4% de amido de milho; 1,5 % de quitosana, 2 % de glicerol e 0,4 % de ácido acético glacial e mantidas sob ventilação. Minicenouras não imersas em suspensão, serviram de controle. Em seguida, as minicenouras foram embaladas em bandejas de polipropileno envoltas em filme de polivinilcloreto e mantidas a 5±1ºC, por 12 ou 15 dias. Minicenouras sem revestimento, apresentaram intenso aumento no índice de esbranquecimento, e no quarto dia, apresentaram entre 21 a 60 % de sua superfície esbranquecida. Independente da concentração de amido na suspensão, o índice de esbranquecimento não alterou. As minicenouras tratadas em suspensão contendo 4 % de amido, não apresentaram sintomas visuais de esbranquecimento durante todo o armazenamento. As minicenouras tratadas em suspensão contendo 2 ou 3% de amido, apresentaram até 20% da superfície esbranquecida, nas extremidades, sem comprometer sua qualidade visual. O tempo para secagem do revestimento foi de proximadamente 2,5; 3,5 e 5h para minicenoura tratadas em suspensão com 2, 3 e 4 %, respectivamente, dificultando o uso de suspensão mais concentrada. A velocidade de perda de massa fresca apresentou a mesma tendência para todos os tratamentos. O revestimento utilizado contendo quitosana, inibiu em 1,2 ciclos logs o crescimento de psicotróficos anaeróbicos após 15 dias, em relação ao controle. A suspensão contendo 2 ou 3 % de amido de milho, proporcionou manutenção da coloração característica de minicenoura e inibiu parcialmente o crescimento de psicotróficos anaeróbicos.

[ENG] This work aimed to develop an edible antimicrobial coating base on a starch- chitosan matrix to evaluate is effect on baby carrot by means of visual quality and anaerobic Psychrotrophs analyses. Carrots of, Esplanada cultivar were harvested at 90 days after planting, were minimally processed in form of baby carrots and immersed in the suspensión coating based on 2; 3 or 4 % maiz starch (w/v) + 2 % glycerol (v/v) + chitosan (1,5 %, w/v) and 0,4 % glacial acetic acid (v/v). All the samples were placed in extended polystyrene trays, wrapped in polyvinylchloride film and stored at 5±1 ºC for 12 or 15 days. Baby carrot no immersed, presented intense increase whiteness index, and 21 – 60 % at days four whitness surface. Independent of the starch concentration in the suspension, the whiteness index did not modify. The Baby carrot treated in suspension contend 4 % of starch, had not presented visual symptoms of whiteness during the storage. The baby carrots treated in suspension contend 2 or 3% of starch, had presented up to 20 % of the whiteness surface, in the extremities, without compromising its visual quality. The time for drying of the coatings was of approximately 2,5; 3,5 and 5h for baby carrot treated in suspension with 2, 3 and 4 %, respectively, making it difficult the use of more concentred suspension. The speed of mass loss presented the same trend for all the treatments. The use chitosan in the coating, inhibited in 1,2 cycles logs the growth of anaerobic psychrotrophs after 15 days, in relation to the control. The suspensión contend 2 or 3 % of maize starch, provided maintenance of the characteristic coloration of baby carrot and inhibited partially the anaerobic psychrotrophs growth.Os autores agradecem ao prof.

Hepatitis C Virus Infection as a Traumatic Experience

Objective The purpose of this study was to evaluate whether individuals consider their HCV infection to be a potentially traumatic experience. Additionally, we investigated its association with Post-Traumatic Stress Disorder (PTSD) and the impact of PTSD diagnosis on health-related quality of life (HRQoL) in HCV infected subjects. Methods We conducted a cross-sectional survey of 127 HCV-infected outpatients recruited at a University Hospital in Salvador, Brazil. All subjects answered an orally-administered questionnaire to gather clinical and socio-demographic data. We investigated traumatic experiences and the subject's perception of the disease using the Trauma History Questionnaire. PTSD and other psychiatric diagnoses were assessed through the Mini International Neuropsychiatric Interview-Brazilian Version 5.0.0 (M.I.N.I. PLUS). HRQoL was assessed using Short-Form 36 (SF-36). Results Approximately 38.6% of the patients considered hepatitis C to be a traumatic experience. Of these, 60.7% had a PTSD diagnosis. PTSD was associated with significant impairment in quality of life for individuals in seven SF-36 domains as shown bymultivariate analysis: Role-Physical (β: −24.85; 95% CI: −42.08; −7.61), Bodily Pain (β: −19.36; 95% CI: −31.28; −7.45), General Health (β: −20.79; 95% CI: −29.65; −11.92), Vitality (β: −11.92; 95% CI: −20.74; −3.1), Social Functioning (β: −34.73; 95% CI: −46.79; −22.68), Role-Emotional (β: −26.07; 95% CI: −44.61; −7.53), Mental Health (β: −17.46; 95% CI: −24.38; −10.54). Conclusion HCV is frequently a traumatic experience and it is strongly associated with PTSD diagnosis. PTSD significantly impaired HRQoL

Toxicidade de extratos vegetais em coccidophilus citrícola (brèthes, 1905) (coleoptera: coccinellidae) / Toxicity of vegetable extracts in coccidophilus citrícola (brèthes, 1905) (coleoptera: coccinellidae)

A palma forrageira NopaleacochenilliferaSalmDyck (CactaceaeJuss.) é o alimento mais utilizado pelos produtores na Bacia Leiteira de Alagoas, principalmente na época do verão. O principal motivo de preocupação da cultura é a cochonilha de escama Diaspisechinocacti (Bouché) (Hemiptera: Diaspididae), que ataca e afeta a produtividade da palma, ocasionando sua morte. Entre os importantes predadores de cochonilhas está a Coccidophiluscitricola (Brèthes, 1905) (Coleoptera: Coccinellidae). Os métodos comumente usados para o controle de cochonilhas são baseados no uso de produtos químicos que causam inúmeros efeitos adversos a organismos não-alvo. Diante da importância de C. citricola como agente de controle biológico o trabalho teve como objetivo avaliar a toxicidade de extratos vegetais sobre este inseto. Para avaliação da mortalidade, uma alíquota de 1mL de cada extrato vegetal e de água (controle) foi pulverizado diretamente sobre os indivíduos. Os tratamentos utilizados foram: Barbatimão na concentração 10%; Barbatimão na concentração 20%; Araticum na concentração 10%; Araticum na concentração 20%; Controle, sem aplicação dos produtos. Foi avaliada a mortalidade após 24, 48, 72 e 96 horas. Os extratos de barbatimão 10%, barbatimão 20%, araticum 10% e araticum 20%, causaram baixo índice de mortalidade, mostrando-se pouco nocivos, demonstrando seu potencial seletivo e de utilização no manejo integrado de cochonilhas com o predador C. citricola

Avaliação de extratos botânicos no controle da cochonilha de escama diaspis echinocacti (brouché, 1833) (hemiptera: diaspididae) / Evaluation of botanical extracts in the control of escama cochonilha diaspis echinocacti (brouché, 1833) (hemiptera: diaspididae)

O estado de Alagoas possui a maior área plantada com palma forrageira do nordeste brasileiro, onde é estimado que haja 500 mil hectares cultivados. A praga mais importante é a cochonilha de escama Diaspis echinocacti (Bouché, 1833) (Hemiptera: Diaspididae) que afeta a produtividade da palma, destacando-se, nos últimos anos, principalmente dificuldades encontradas para o seu controle. Os métodos comumente usados para o controle de cochonilhas são baseados no uso de produtos químicos que causam inúmeros efeitos adversos ao meio ambiente. É importante a realização de pesquisas visando o desenvolvimento de novos produtos para o controle de pragas. O trabalho teve como objetivo verificar o potencial inseticida de extratos botânicos no controle de D. echinocacti. Para avaliação da mortalidade, uma alíquota de 1 mL de cada extrato vegetal e de água (controle) foi aplicada diretamente sobre secções de palma de três centímetros quadrados, infestados com fêmeas adultas. Os tratamentos utilizados foram: Barbatimão na concentração 10%; araticum na concentração 10%; araticum na concentração 20%; controle, sem aplicação dos produtos. Foi avaliada a mortalidade após 24, 48 e 72 horas. Entreos extratos utilizados, o de barbatimão 10% causou maior mortalidade em relação ao controle. Entretanto, o índice de mortalidade apresentado é considerado baixo, demonstrando que este extrato não pode ser considerado eficiente para o controle da praga D. echinocacti.

Relationship between circulating VCAM-1, ICAM-1, E-selectin and MMP9 and the extent of coronary lesions

OBJECTIVES: Inflammatory molecules play a role in the development of atherosclerosis, which is the primary origin of cardiovascular disorders. However, to the best of our knowledge, no study has attempted to investigate the relationship between these circulating molecules and the prediction of cardiovascular risk. The present study aimed to investigate the relationships of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, E-selectin and matrix metalloproteinase 9 serum concentrations with the extent of coronary lesions. METHODS: Seventy-four individuals who were undergoing coronary angiography for the first time for diagnostic purposes were enrolled in this study. The extent of the coronary lesion was assessed using the Friesinger Index, and subjects were classified into four groups: no lesions, minor lesions, intermediate lesions and major lesions. Serum biochemical parameters and serum concentrations of vascular cell adhesion molecule-1, intercellular adhesion molecule-1, E-selectin and matrix metalloproteinase 9 were analyzed. RESULTS: The vascular cell adhesion molecule-1 concentration was higher than 876 ng/mL in individuals with intermediate and major lesions (

Clonal chromosomal mosaicism and loss of chromosome Y in elderly men increase vulnerability for SARS-CoV-2

The pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2, COVID-19) had an estimated overall case fatality ratio of 1.38% (pre-vaccination), being 53% higher in males and increasing exponentially with age. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, we found 133 cases (1.42%) with detectable clonal mosaicism for chromosome alterations (mCA) and 226 males (5.08%) with acquired loss of chromosome Y (LOY). Individuals with clonal mosaic events (mCA and/or LOY) showed a 54% increase in the risk of COVID-19 lethality. LOY is associated with transcriptomic biomarkers of immune dysfunction, pro-coagulation activity and cardiovascular risk. Interferon-induced genes involved in the initial immune response to SARS-CoV-2 are also down-regulated in LOY. Thus, mCA and LOY underlie at least part of the sex-biased severity and mortality of COVID-19 in aging patients. Given its potential therapeutic and prognostic relevance, evaluation of clonal mosaicism should be implemented as biomarker of COVID-19 severity in elderly people. Among 9578 individuals diagnosed with COVID-19 in the SCOURGE study, individuals with clonal mosaic events (clonal mosaicism for chromosome alterations and/or loss of chromosome Y) showed an increased risk of COVID-19 lethality

Pervasive gaps in Amazonian ecological research

Biodiversity loss is one of the main challenges of our time,1,2 and attempts to address it require a clear un derstanding of how ecological communities respond to environmental change across time and space.3,4 While the increasing availability of global databases on ecological communities has advanced our knowledge of biodiversity sensitivity to environmental changes,5–7 vast areas of the tropics remain understudied.8–11 In the American tropics, Amazonia stands out as the world’s most diverse rainforest and the primary source of Neotropical biodiversity,12 but it remains among the least known forests in America and is often underrepre sented in biodiversity databases.13–15 To worsen this situation, human-induced modifications16,17 may elim inate pieces of the Amazon’s biodiversity puzzle before we can use them to understand how ecological com munities are responding. To increase generalization and applicability of biodiversity knowledge,18,19 it is thus crucial to reduce biases in ecological research, particularly in regions projected to face the most pronounced environmental changes. We integrate ecological community metadata of 7,694 sampling sites for multiple or ganism groups in a machine learning model framework to map the research probability across the Brazilian Amazonia, while identifying the region’s vulnerability to environmental change. 15%–18% of the most ne glected areas in ecological research are expected to experience severe climate or land use changes by 2050. This means that unless we take immediate action, we will not be able to establish their current status, much less monitor how it is changing and what is being lostinfo:eu-repo/semantics/publishedVersio
