I tumori odontogenici sono neoplasmi che si sviluppano nella regione delle ossa gnetici, provenienti da tessuti odontogenici dalla proliferazione del tessuto epiteliale, mesenchymal o entrambi. Tra questi, possiamo citare la cheratociasta odontogenica che ha le sue caratteristiche e totalmente differenziata da qualsiasi altra patologia orale che presenta una sfida per la diagnosi al professionista. L’obiettivo di questo lavoro è quello di condurre una revisione della letteratura sulla cheratocista dentale e affrontare le caratteristiche cliniche e radiografiche associate a questa patologia, così come il suo approccio terapeutico.
THE RELATIONSHIP BETWEEN EDUCATION, EMPLOYMENT AND INCOME
Authors: PALAŠČÁKOVÁ LENKA
Published: October 2020

The issue of interrelationships between education, employment and the level of income evaluation is a cross-cutting nature, where the economic, social, political and legal levels are intertwined. Its broader context predicts its thematic coverage. The article presents preliminary results of the mutual relationship between acquired skills and the level of education achieved and the ability of the individual to become involved in the labor market. The aim of the article is to determine, using statistical and analytical methods, the correlation between the employment rate and the level of education attained in the EU countries and within the territory of the Slovak Republic. On the basis of the initial analysis the authors aim to answer the question if university graduates achieve higher incomes than secondary-educated people. Eventually they try to propose solutions and measures that are necessary for increasing the level and value of human capital, especially in the Slovak Republic.
THE IMPACT OF VALUE ON THE EFFECTIVENESS OF MARKETING COMMUNICATION OF LOCAL COMPANIES
Authors: Demjanovičová Mária
Published: October 2020

Local companies from different areas that are successful on social networks were chosen for the survey. The aim of the article is to identify the company's corporate values and their impact on the results of marketing communication as well as to find the attributes that are used in such successful companies and to make generalization of them.

Several local companies do not invest a lot of money in marketing, but their results on social networks are comparable or even better than the ones of corporations managed by social networking agencies. What is the essence of their success and how it impacts the value of the company?

The paper describes perceived value of entrepreneurs from small local companies through quality methods of research – personal interview and theoretical basis in this field. This data allowed to prepare a research, which shows four interest areas of the perceived value in small companies. The companies were selected from Slovakia, from among small and medium companies in local area in May 2019. In the research seventeen companies were involved and the main objective of the research was to gain as much information as possible about companies value and the value perceived by entrepreneurs. For this reason personal interview was used. The research result can bring parameters of perceived value in first step and later can provide a helpful model of managing value and the steps for understanding and creating the value of local company.
Tools for Reconciling Professional and Personal Roles in Poland. Challenges and Barriers
Authors: Sienkiewicz Łukasz
Published: October 2020

One of the key challenges faced by today’s workers is to live at an ever-increasing pace, which creates a conflict between professional and private life. This results from the extension and intensification of working time, the need for constant improvement of competences and, as a result, lack of free time for family life or rest. More and more companies are opting for specialised programmes to prevent imbalances between professional and private life (Work-Life Balance – WLB). However, the scope of solutions applied by Polish employers is not systematically examined. Therefore, the article reviews and analyses the applied solutions in the field of reconciliation of professional and personal life (including family life) in enterprises operating in Poland, as well as barriers and challenges of their implementation. Identified challenges of financial, legislative, organisational and cultural character limit the practical use of such mechanisms.

Neoplasms involving plasmacytoid dendritic cells (pDC) include blastic pDC neoplasms (BPDCN) and other pDC proliferations, where pDC are associated with myeloid malignancies: most frequently chronic myelomonocytic leukemia (CMML) but also acute myeloid leukemia (AML), hereafter named pDC-AML. We aimed to determine the reactive or neoplastic origin of pDC in pDC-AML, and their link with the CD34+ blasts, monocytes or conventional DC (cDC) associated in the same sample, by phenotypic and molecular analyses (targeted next-generation sequencing, 70 genes). We compared 15 pDCAML at diagnosis with 21 BPDCN and 11 normal pDC from healthy donors. CD45low CD34+ blasts were found in all cases (10-80% of medullar cells), associated with pDC (4-36%), monocytes in 14 cases (1-10%) and cDC (two cases, 4.8-19%). pDC in pDC-AML harbor a clearly different phenotype from BPDCN: CD4+ CD56– in 100% of cases, most frequently CD303+, CD304+ and CD34+; lower expression of cTCL1 and CD123 with isolated lymphoid markers (CD22/CD7/CD5) in some cases, suggesting a prepDC stage. In all cases, pDC, monocytes and cDC are neoplastic since they harbor the same mutations as CD34+ blasts. RUNX1 is the most commonly mutated gene: detected in all AML with minimal differentiation (M0-AML) but not in the other cases. Despite the low number of cases, the systematic association between M0-AML, RUNX1 mutations and an excess of pDC is puzzling. Further evaluation in a larger cohort is required to confirm RUNX1 mutations in pDC-AML with minimal differentiation and to investigate whether it represents a proliferation of blasts with macrophage and DC progenitor potential.

Introduction: Chronic heart failure with reduced ejection fraction is a major complication of diseases involving myocardium. Despite numerous pharmacological interventions and invasive therapeutic techniques, therapeutic options for end stage heart failure remain limited to left ventricular assist device & organ transplantation. Regenerative medicine may bring hope here.

Method: This pilot study was carried out at the Department of cardiology in collaboration with department of haematology, Bangabandhu Sheikh Mujib Medical University, Dhaka, from October 2017 to March 2018. Considering inclusion & exclusion crieteria ten (10) patients were taken in stem cell group and ten (10) patients in control group. Patients in the control arm received standard of care in accordance with practice guidelines for heart failure management (GDMT). Patients in the cell therapy arm received, in addition to standard of care, bone marrow–derived cardiopoietic stem cells (G-CSF) meeting quality release criteria. Baseline clinical and echocardiographic data were obtained and recorded in pre-formed data sheet. Close liaison was maintained with all patients and followed up after 30 days & after 3 months and for any complication. The absolute change in 6 MWD from baseline to 30 days, 3 months & 6 months improved significantly in the both groups. But significant improvement was found at 6 months follow up of 6MWD between the two groups (300±28 vs 375±25, p= 0.04). Baseline BORG scale was similar in the control group and the SCT group (8.1±0.56 and 8.3±0.67 respectively, P= 0.45). The absolute change in BORG scale from baseline to 30 days, 3 months & 6 months improved significantly in the both groups. But improvement was not statistically significant in between the two groups (p= 0.32, 0.45, 0.23 respectively). Echocardiographic observation also revealed a similar baseline LVIDd, LVEF level in the control group and the SCT group which was not statistically significant (p = 0.45, 0.52 respectively). Gradual improvement in LVIDd were found at 30 days, 3 months, 6 months follow up observation but statistically significant absolute change was found only at 6 months follow up in between groups (62.4±1.8 vs 56±2.4, p=0.03). Baseline LVEF were less than 30% in both control & SCT group (29.5±0.8% & 28.7±1.3% respectively). The echocardiographic evaluation also revealed a significant increase in LVEF at 6 months (34% ±1.6 and 40% ± 2.5%, p = 0.04) of follow-up in between group but not at 30 days & 3 months follow up.

Acute coronary syndrome may leads to heart failure. Severity of heart failure is identified by NYHA classification clinically. Color Doppler echocardiography is the key investigation to identify the acute systolic heart failure. For the quantification of systolic heart failure diagnosis, Ejection fraction (EF) can be measured by Simpson method. EF > 30% is defined as severe systolic heart failure. Pulsus alternans is found in severe heart failure patients. Pulsus alternans is a poor prognostic sign of severe heart failure patients in acute MI setting. This cross sectional observation study was aimed to identify the objective evidence of Pulsus alternance noninvasively by Echocardiography. Color Doppler echocardiography was done 100 acute coronary syndrome with heart failure NYHA III and IV patients in department of Cardiology, BSMMU, from July 2018 to June 2019. Age 18 to 70 yrs, male is 79 and female is 21. Pulsus alternans was found in 32 patients, 39 had low volume and 29 had normal volume pulse. 50% patients had ST depression and T inversion and diagnosed as case of Unstable Agina or Non STEMI, 44 had STEMI and 7 had developed new onset of LBBB. 87 Patients who have EF < 30 % was marked as Severe LV systolic dysfunction. Among them, 3 had mild, 14 had moderate and rest 70 had severe Mitral regurgitation. 38 (43.67%) patients had Doppler alternans in severe LV systolic dysfunction group. P value for Doppler alternans is 0.039 which is significant. Doppler alternans by Echocardiography in Severe LV systolic dysfunction patients showed 49% sensitivity and 78% specificity. 38 patients had Severe RV systolic dysfunction by M- mode echo measurement of TAPSE<10 mm. 22 (57.89%) had Doppler alternans across Tricuspid valve in case of severe RV systolic dysfunction. Sensitivity of Doppler alternans by Doppler Echocardiography in TV severe RV systolic dysfunction is 51% and specificity for it is 82%.

Plants’ biochemical responses to water deficit are associated with their ability to synthesize accumulate osmolytes compatible to regulatory properties of water potential. The aim of the current study is to evaluate carbon and nitrogen metabolism in Tachigali vulgaris plants subjected to three water suspension periods. The experiment was carried out in greenhouse and followed a completely randomized design, at 3 x 2 factorial arrangement (three times: zero, five and ten water suspension days; and two water conditions: control and water deficit), with 4 repetitions; results were subjected to analysis of variance and means were compared through t-test at 5% probability level, in statistical package (Assistat 7.7 beta). The following variables recorded decreased values: relative water content RWC in leaf tissue (by 32.14%); nitrate ion in leaves (by 18.67%) and in roots (by 14.40%); nitrate reductase enzyme activity in leaves (by 17.06%) and roots (by 15.77%); starch concentration in leaf tissue (by 44.98%) and roots (by 21.07%). On the other hand, the following variables recorded increased values: free ammonium concentration in leaves (by 64.83%) and roots (by 1.61%); total soluble amino acids in leaf tissue (by 28.03%) and roots (by 8.42%); total soluble carbohydrates in leaves (by 3.12%) and roots (by 11.05%); sucrose in leaves (by 4.77%) and roots (by 24.77%); proline in leaves (by 193.58%) and roots (by 57.26%). Biochemical processes observed in T. vulgaris plants were affected by water deficit, which indicated that this species is capable of adopting mechanisms and strategies in order to survive under stressful conditions.

Milho-verde é um cereal amplamente consumido no mundo todo, com alta demanda de produção. A produtividade do milho-verde está ligada à disponibilidade hídrica e de nitrogênio, sendo o conhecimento da interação entre estes fatores essencial para alcançar os melhores rendimentos da cultura, dependendo das condições edafoclimáticas de uma determinada região. No presente trabalho, investigamos o impacto de diferentes lâminas de água (50%, 75%, 100%, 125% da reposição hídrica da evapotranspiração) e de doses de nitrogênio (0, 70, 140, 210 kg N ha-1), além da interação entre esses dois fatores sobre a morfofisiologia e produção do milho-verde cv. Agroceres 1051 cultivado em cerrado goiano. As diferentes lâminas de água e dosagens de nitrogênio não afetaram parâmetros fisiológicos como fotossíntese liquida, condutância estomática, transpiração e fluorescência. Em relação aos parâmetros morfológicos e de produção, a aplicação da lâmina de água de 125% promoveu aumento no comprimento da espiga sem palha (CESP), número de cariopses por fileira (NCF), diâmetro do colmo, massa verde da planta sem espiga (MVPSE) e no peso da espiga com palha. A adubação com dose de 210 kg ha-1 de nitrogênio aumentou comprimento da espiga com e sem palha (CECP e CESP), NCF, MVPSE, e o diâmetro e peso da espiga com palha (DECP e PECP). Houve correlação positiva entre a área foliar (AF) e os parâmetros de produtividade. A eficácia da adubação nitrogenada foi limitada pela disponibilidade hídrica para os parâmetros AF, altura da planta, número de folhas e comprimento e largura da folha de inserção da espiga.

No Brasil, o câncer de mama ocupa a segunda colocação no que tange as neoplasias do público feminino. As medidas preventivas incluem ações primárias e secundárias, sendo as primárias referentes a um estilo de vida saudável e as secundárias apresentam-se mais específicas, estando ligada ao autoexame, avaliações periódicas da mama e realização de exames específicos, visando o diagnóstico precoce e o aumento na chance de cura. Dessa forma, este estudo objetivou relatar uma ação de educação em saúde ocorrida no âmbito da atenção primária de saúde, cuja proposta perpassava pela prevenção do câncer de mama a partir do reconhecimento prévio de suas manifestações, bem como da manutenção de hábitos saudáveis, visando a promoção da saúde dessas mulheres. Este estudo caracteriza-se como descritivo com abordagem qualitativa, do tipo relato de experiência, a partir da utilização da Teoria da Problematização fundamentada na metodologia do Arco de Charles Maguerez. Como principais resultados alcançados enfatiza-se que foi possível sensibilizar as mulheres sobre a importância do autocuidado adequado, além de oportunizar a participação ativa e ofertar um suporte adequado sobre os aspectos que permeiam a doença e suas chances de cura através do diagnóstico prévio. Ademais, conclui-se que a ação desenvolvida serviu como mecanismo consolidador dos aspectos que constituem a educação em saúde, reiterando a função fundamental da enfermagem no processo do cuidar.

Published: October 2020

Objetivou-se descrever o potencial das matas de babaçu (Attalea speciosa Mart. ex Spreng.) para a produção de pólen apícola, bem como determinar a composição nutricional do produto. Para tanto, foram instalados coletores de pólen em colmeias de abelhas africanizadas (Apis mellifera L.) do Apiário Experimental do Centro de Práticas Zootécnicas do Instituto de Ensino Superior Múltiplo, em uma área de mata de babaçu, no município de Timon, Maranhão. Amostras de pólen de cada colônia foram coletadas diariamente durante a primeira semana de cada mês nos períodos de floração do babaçu e levadas para estufa. Posteriormente, as amostras foram limpas, colocadas em embalagens plásticas, separadas por data de coleta. Pesquisou-se no microscópio, a predominância do tipo polínico referente ao babaçu, sendo que as amostras provenientes da referida palmeira foram pesadas e submetidas à avaliação do teor de proteína bruta e da quantidade de aminoácidos. Observou-se que apenas a amostra de pólen referente à coleta realizada no mês de outubro foi considerada monofloral (51,8g/colmeia) e a ocorrência do pólen de babaçu diminuiu gradativamente durante os meses seguintes. Em relação à composição nutricional, embora o teor de proteína (23,12%) tenha sido considerado semelhante e muitas vezes superior ao encontrado na literatura, as quantidades de aminoácidos essenciais atenderam parcialmente as exigências nutricionais das abelhas, o que pode ter influenciado no comportamento de forrageamento desses insetos nas matas de babaçu.

O objetivo desse trabalho foi avaliar o extrato de orégano (EO) (Origanum vulgare) como aditivo em rações para Betta splendens. Utilizou-se 40 juvenis de B. splendens, com peso médio inicial de 0,30 ± 0,02g, num delineamento inteiramente casualizado com quatro tratamentos e dez repetições, por 45 dias. Os tratamentos consistiram em uma ração isenta de extrato de orégano (0% de EO) e outras três rações adicionadas de EO (0,25%; 0,50% e 0,75%). As variáveis analisadas foram: peso inicial (PI) e final (PF), ganho de peso médio (GP), taxa de eficiência proteica, comprimento da cabeça (CCAB), índice de perfil (IPERFIL), índice de cabeça (ICAB), comprimento total (CTOT) e padrão (CPAD)e altura. Como variável de avaliação do estresse oxidativo foi verificado a atividade da enzima catalase (CAT) no tecido muscular. Os dados foram submetidos à ANOVA, teste de Tukey e regressão a 5% de probabilidade. Não se observou efeito (p>0,05) dos tratamentos sobre as variáveis avaliadas de: PF, CCAB, ALT, IPERF, ICAB e TCE. No entanto, verificou-se efeito linear crescente à medida que se aumentou adição de EO nas rações sobre o GP, CPAD, CTOTAL e CAT. Recomenda-se assim o uso de rações com 0,75% de EO para Betta splendens.

Authors: Monteiro Daiane da Rosa
Published: October 2020

A cirurgia é uma das alternativas terapêuticas para solucionar um problema de saúde. Sabe-se que os pacientes apresentam as mais diversas reações psicoemocionais no período pré-operatório. A assistência de enfermagem pré-operatória representa o principal instrumento para o estabelecimento de uma relação de confiança entre o enfermeiro e o paciente, buscando proporcionar a redução de reações traumáticas e uma melhoria da qualidade de vida. Objetiva-se conhecer as lembranças e reações psicoemocionais de pacientes durante a consulta de enfermagem pré-operatória de artroplastia total de quadril. Trata-se de uma pesquisa exploratória descritiva, com abordagem qualitativa. Realizou-se entrevistas com oito pacientes e os relatos foram transcritos no período de junho a agosto de 2019 para uso do método de análise de conteúdo. Originou-se duas categorias conforme relato dos pacientes, a primeira trouxe as reações e vínculos estabelecidos entre o profissional enfermeiro e o paciente durante a consulta ambulatorial e a segunda mostrou as percepções daqueles orientados durante as visitas domiciliares. Percebeu-se a responsabilização do paciente na sua recuperação e no seu cuidado com a saúde mental. Há a necessidade de novas pesquisas que abordem os transtornos psíquicos em diversas áreas, não somente em ambientes pré-cirúrgicos, instigando reflexões para construção de novas práticas de trabalho para proporcionar um atendimento qualificado, efetivo e de excelência.
Gas stations in Belém-PA: the environmental licensing and the risks of soil and groundwater contamination
Authors: Souto Cleyanne Kelly Barbosa , Penner Giovanni Chaves
Published: October 2020

The environmental licensing process is a guarantee of a safe environment for polluting activities. The present work analyzed Belém-PA environmental license files for the gas station segment in association with urban land use and the shallow free aquifer, these factors can compromise environmental quality and risks to the public health. For this purpose, there was carried out a bibliographic research, as well as a survey of information in databases of the municipal, state, federal registry and fire department. Besides, it was concluded that the number of licensed gas stations does not match the reality, where 130 projects were identified. It was found that 33 gas stations, or 25%, meet the necessary licenses and 97 gas stations, or 75%, have some pending issues, showing the need for greater attention to the environmental licensing process, as well as the need to regularize the enterprises with some pending in licensing, to have adequate management control over such activity. Bearing in mind that this is a potential activity that causes environmental damage, it is often located within the urban areas and under conditions of shallow groundwater can compromise the quality of soil and groundwater, with risk to human health.
Conciliação e mediação pelo foro extrajudicial: critérios e possibilidades
Authors: Cardoso Kelly , Iocohama Celso Hiroshi , Oliveira Thiago Mattos de
Published: October 2020

O presente trabalho aborda algumas mudanças legislativas, bem como, normativas do Conselho Nacional de Justiça que incentivam a realização de resolução de conflitos por meios alternativos, como a conciliação e a mediação, pela via extrajudicial. O monopólio do Poder Judiciário para a solução de conflitos já não atende mais a excessiva demanda processual, tornando a desjudicialização um meio viável para atender aos anseios sociais. A realização da conciliação e da mediação pelo foro extrajudicial mantém a concretização do princípio do acesso à justiça, de forma célere e econômica. Entretanto, além de mudanças legislativas, é mister uma mudança comportamental dos interessados, para que a via extrajudicial tenha real aplicabilidade e efeitos satisfativos.

Changes to phytoplankton community composition could have major consequences for wider ecosystem functioning and may occur in response to climate change. Here we describe multi-decadal variability in phytoplankton community structure using taxonomic data from the Continuous Plankton Recorder collected in the North-East Atlantic from 1969-2013, using a total of 42 diatom and dinoflagellate taxa. We considered a range of characteristics of community structure, including taxonomic diversity and community stability and disorder, and how these characteristics change in response to sea surface temperature, mixed layer depth and the North Atlantic Oscillation. We found that phytoplankton community composition was largely stable on interannual timescales. A change in community composition occurred between 1985 and 1995 due to an increased dominance of 2 diatom taxa (Rhizosolenia styliformis and Thalassiosira spp.); however, after this period, the community returned to its previous composition. Further, a community disorder analysis found that phytoplankton compositional structure became more rigid in recent years, which may lead to an eventual community shift in the future. In contrast to previous studies that revealed relationships between total phytoplankton abundance or biomass and environmental forcing, we found that community structure had, at most, a very weak relationship with the environmental parameters tested. Changes to the physical environment may therefore have less influence at interannual timescales on phytoplankton community structure than previously thought.

Protective legislation and management have led to an increase in California’s sea otter Enhydra lutris nereis population. While sea otter recovery has been linked to ecosystem benefits, sea otter predation may negatively affect commercially valuable species. Understanding the potential influence of sea otters is of particular importance as their range expands into estuaries that function as nurseries for commercially valuable species like Dungeness crab Metacarcinus magister. We consider how sea otter predation has affected the abundance and size of juvenile Dungeness crab in Elkhorn Slough, California, USA, and analyzed cancrid crab abundance and size across 4 California estuaries with and without sea otters to understand how biotic and abiotic factors contribute to observed variation in crab size and abundance. We compared trends in southern sea otters relative to Dungeness crab landings in California to assess whether increasing sea otter abundance have negatively impacted landings. In Elkhorn Slough, juvenile Dungeness crab abundance and size have declined since 2012, coinciding with sea otter population growth. However, the impact of sea otters on juvenile Dungeness crab size was habitat-specific and only significant in unvegetated habitat. Across estuaries, we found that cancrid crab abundance and size were negatively associated with sea otter presence. While abiotic factors varied among estuaries, these factors explained little of the observed variation in crab abundance or size. Although we found evidence that sea otters can have localized effects on cancrid crab populations within estuaries, we found no evidence that southern sea otters, at recent population sizes, have negatively impacted Dungeness crab landings in California from 2000-2014.

Polar regions are facing rapid temperature increase. In Arctic fjord systems, increased temperatures result in hyposalinity caused by the melting of sea ice and glaciers and freshwater run-off. Additionally, enhanced freshwater discharge and intrusion of nutrient-rich Atlantic water may result in nutrient input in summer. Combined, these factors might have a strong impact on primary producers, such as the abundant kelp speciesSaccharina latissima, an important foundation species in Arctic shallow-water coastal ecosystems. We ran 2 short-term 2factor experiments with field samples from Kongsfjorden (Svalbard) to evaluate the impact of temperature increase in summer combined with hyposalinity (temperature × salinity) or nutrient enrichment (temperature × nutrients) on the physiological and biochemical status of ArcticS. latissima. In the temperature × salinity experiment, growth and maximum photosynthetic quantum yield of photosystem II (Fv/Fm) were generally not affected. Temperature increase resulted in increased C:N ratios, based on decreasing nitrogen assimilation. Overall, hyposalinity had no severe effect but resulted in lower phlorotannin concentrations. Growth andFv/Fmimproved with increasing temperatures and nutrient enrichment. The de-epoxidation state of the xanthophyll cycle and mannitol declined at higher temperatures. Regarding other biochemical response variables, nutrients had no major impact (temperature × nutrients). In conclusion, in line with its broad latitudinal distribution range and adaptability,S. latissimaproved to be highly resilient to changing abiotic drivers and will likely be promoted by warming in the future Arctic.

Significant benefit of soil organic matter (SOM) to crop productivity is scientifically well documented. The main constituents and active fractions of SOM are humic substances (HS) and phenolic compounds. Since both these two components strongly impact plant–soil relationship, it is importantly from an ecological point of view to discriminate their biological effects and relating them to their composition. In this study we compared the biological effects of HS, and the soil water soluble phenols (SWSP) on growth, antioxidant activities, carbohydrates, proteins, phenols, and vitamins of Pinus laricio callus. Each extract was assessed for the content of low molecular weight organic acids, soluble carbohydrates, fatty acids, and phenolic acids. Moreover, Fourier transform infrared (FT-IR) and surface-enhanced Raman scattering (SERS) spectroscopies were applied to study their molecular structure. The results showed that HS produced better callus growth compared to the control and SWSP. Carbohydrates decreased in presence of HS while proteins, vitamin C and E increased. In contrast, in callus treated with SWSP the amount of glucose and fructose increased as well as all the antioxidant activities. The data evidenced that HS rich in tartaric and fatty acids had beneficial effects on callus growth contrary to soil water-soluble phenols rich in aldehydes, and syringic, ferulic, and benzoic acids.

Salinization of agricultural land is an expanding phenomenon, which requires a multi-level strategy to counteract its deleterious effects on crop yield and quality. Plant biostimulants are increasingly used in agriculture with multiple purposes, including protection against abiotic stresses such as drought and salinity. The complex nature of plant biostimulants, however, makes it difficult to establish a cause–effect relationship between the composition of the commercial product and its expected effects. Here, we demonstrate that field applications of two algal derivatives (Rygex, R and Super Fifty, SU) cause a 26% reduction in shoot biomass and a remodulation of the root-to-shoot ratio under moderately saline irrigation (6.3 dS m−1). Moreover, plants treated with the two algal derivatives showed lower leaf water potential and improved water use efficiency under control conditions, suggesting an osmo-priming effect by these two products. These pre-adaptation responses increased tomato yield by 49% (R) and 70% (SU) regardless of the salinity level, with a remarkable reallocation of the biomass toward the fruits. Overall, our results suggest that the application of these two biostimulants can be useful in the open field to protect tomato plants from osmotic stress due to seasonal salinization, a phenomenon that typically occurs in arid and semi-arid environments.

The aim of this study was to evaluate the antibacterial properties of graphene oxide (GO) against Enterococcus faecalis in vitro conditions and when used to coat dentin surface to prevent E. faecalis adhesion. The ATCC strain of E. faecalis 29212 has been used to perform a viability test. The pellet was suspended in ultrapure water, NaCl, PBS buffer, CaCl2 and MgCl2, Luria−Bertani broth solutions. The viability was evaluated by the colony forming unit counting method. Atomic force microscopy images and the measure of surface zeta potential variation were analyzed. Dentin discs were covered with a film of GO (n = 15) or were not treated (n = 15). Bacterial suspension was added to each sample of dentine discs and microbial counts were calculated. Statistically significant differences between two groups were assessed by a two-tailed unpaired t-test. Bacteria cell morphology was investigated with scanning electron microscopy. The highest growth inhibition was obtained in ddH2O and CaCl2 solution while, in PBS and NaCl, GO had poor antibacterial efficacy with a growth enhancing effect in the latter. GO on dentin discs demonstrated high antibacterial activity. GO film has demonstrated acceptable adhesion properties to root dentin and a role in the inhibition of bacterial film proliferation and biofilm formation.

Coenzyme Q10 (CoQ) treatment monitoring is a matter of debate since CoQ distribution from plasma to blood cells and tissues is not fully understood. We aimed to analyze the CoQ levels in a wide set of human biological samples (plasma, blood mononuclear cells (BMCs), platelets, urinary cells, and skeletal muscle) from a group of 11 healthy male runners before and after CoQ supplementation. The CoQ content in the different samples was analyzed by HPLC coupled to electrochemical detection. No significant differences were observed in the CoQ levels measured in the BMCs, platelets, and urine after the one-month treatment period. Plasma CoQ (expressed in absolute values and values relative to total cholesterol) significantly increased after CoQ supplementation (p = 0.003 in both cases), and the increase in CoQ in muscle approached significance (p = 0.074). CoQ levels were increased in the plasma of all supplemented subjects, and muscle CoQ levels were increased in 8 out of 10 supplemented subjects. In conclusion, the analysis of CoQ in plasma samples seems to be the best surrogate biomarker for CoQ treatment monitoring. Moreover, oral CoQ administration was effective for increasing muscle CoQ concentrations in most subjects.

Both tissue repair and regeneration are a priority in regenerative medicine. Retinitis pigmentosa (RP), a complex retinal disease characterized by the progressive loss of impaired photoreceptors, is currently lacking effective therapies: this represents one of the greatest challenges in the field of ophthalmological research. Although this inherited retinal dystrophy is still an incurable genetic disease, the oxidative damage is an important pathogenetic element that may represent a viable target of therapy. In this review, we summarize the current neuroscientific evidence regarding the effectiveness of cell therapies in RP, especially those based on mesenchymal cells, and we focus on their therapeutic action: limitation of both oxidative stress and apoptotic processes triggered by the disease and promotion of cell survival. Cell therapy could therefore represent a feasible therapeutic option in RP.
Dissolved Oxygen Forecasting in Aquaculture: A Hybrid Model Approach
Authors: Eze Elias , Ajmal Tahmina
Published: October 2020

Dissolved oxygen (DO) concentration is a vital parameter that indicates water quality. We present here DO short term forecasting using time series analysis on data collected from an aquaculture pond. This can provide the basis of data support for an early warning system, for an improved management of the aquaculture farm. The conventional forecasting approaches are commonly characterized by low accuracy and poor generalization problems. In this article, we present a novel hybrid DO concentration forecasting method with ensemble empirical mode decomposition (EEMD)-based LSTM (long short-term memory) neural network (NN). With this method, first, the sensor data integrity is improved through linear interpolation and moving average filtering methods of data preprocessing. Next, the EEMD algorithm is applied to decompose the original sensor data into multiple intrinsic mode functions (IMFs). Finally, the feature selection is used to carefully select IMFs that strongly correlate with the original sensor data, and integrate into both inputs for the NN. The hybrid EEMD-based LSTM forecasting model is then constructed. The performance of this proposed model in training and validation sets was compared with the observed real sensor data. To obtain the exact evaluation accuracy of the forecasted results of the hybrid EEMD-based LSTM forecasting model, four statistical performance indices were adopted: mean absolute error (MAE), mean square error (MSE), root mean square error (RMSE), and mean absolute percentage error (MAPE). Results are presented for the short term (12-h) and the long term (1-month) that are encouraging, indicating suitability of this technique for forecasting DO values.
Seismic Responses of GRS Walls with Secondary Reinforcements Subjected to Earthquake Loading

Published: October 2020

Secondary reinforcement has been proven to be effective in increasing the performance of geosynthetic-reinforced soil (GRS) walls under working stress conditions, enabling an eco-friendlier environment. However, the seismic responses of GRS walls with secondary reinforcements are still unclear. In this study, in-depth finite element analyses were used to investigate the seismic responses of GRS walls with secondary reinforcement subjected to earthquake motions. The numerical procedure was first validated using measurements obtained from both a field GRS wall with secondary reinforcement and benchmark large-scale shaking table tests. Then, the validated GRS walls procedure was utilized to explore the effects of secondary reinforcement length and stiffness, the vertical spacing of the primary reinforcement, and wall height on the seismic responses. Based on the study, the following findings can be drawn: (i) the secondary reinforcement length and stiffness under various wall heights and peak ground accelerations (PGAs) have a limited influence on the relative lateral facing displacement and acceleration amplification, however, they can significantly decrease the connection load and the maximum reinforcement load; (ii) increasing the length of the secondary reinforcement is more effective for reducing the connection load and the maximum reinforcement load than increasing the stiffness of the secondary reinforcement; (iii) the effect of secondary reinforcement is more evident for greater wall height, the larger vertical spacing of primary reinforcement, and smaller PGA; and (iv) GRS walls with secondary reinforcement could ease the acceleration amplification. The study has highlighted the salient effect of secondary reinforcement on GRS wall performance under seismic conditions.
