Background: Dedicated conferences in palliative care have been proposed as an ACGME requirement for radiation oncology (RO) residency programs. We assessed RO program directors’ attitudes towards discrete palliative care skills. Methods: In April 2019, we surveyed 93 United States RO residency program directors. The survey assessed program directors’ views of 27 discrete palliative care skills in eight domains adapted from the American Society of Clinical Oncology/American Academy of Hospice and Palliative Medicine guidance statement defining high-quality palliative care in oncology. Using a nine-point scale, respondents rated each skill on three constructs: 1) importance to high-quality cancer care, 2) scope within RO practice, and 3) importance in RO residency education. Skills were categorized as “Included” (median score ≥7 for all constructs), “Excluded” (median score ≤3 for all constructs), or “Uncertain” (all other skills) using a composite score of all constructs. Results: Twenty-nine program directors (response rate 31%) completed the survey. Of the 27 skills, respondents rated 100% of the skills as important to care (median score ≥7), 70% of the skills as within the scope of RO practice, and 81% of the skills as important to resident education. No skills were rated as unimportant to care, out of scope, or unimportant to resident education (median score ≤3). Seventy percent of skills were categorized as “Included.” The domains of Caregiver Support (100%), End of Life Care (66%), and Spiritual/Cultural Assessment and Management (33%) had the highest proportions of skills rated as “Uncertain.” Time limitations (28%) and lack of education (28%) were rated as the main barriers to further integration of palliative care into RO. Conclusions: RO program directors value palliative care skills within RO. The majority of the assessed skills were rated as important to care, within scope of practice, and important to resident education.

Background: Intractable pain is one of the invincible entities in cancer and about 75% of cancer patients require inpatient hospital admission at least once in their treatment course. Palliative care service has a significant role in managing cancer pain and thus reducing the recurrent hospital admissions. Methods: We analyzed the association of Mortality Rate (MR) with age, sex, race, emergency admission, hospital regions among patients admitted for Neoplasm Related Pain (NRP). Data from the National Inpatient Sample (NIS) database for the year 2016 was reviewed. Patients admitted with a principal diagnosis of NRP were identified using ICD-10 code. The prevalence of each cancer and characteristics of admissions were also studied. Statistical analysis was performed using STATA and the association was depicted with Chi-Square test. Results: A total of 28609 admissions with a primary diagnosis of NRP was identified. The mean age of admission was found to be 59.38 ± 0.08, with 53.19% patients ≥ 60 years of age. 51.39% were females, 65.58% were Caucasians,16.25% were African Americans. The overall inpatient hospital MR for NRP was 8.16%. There was a significant difference in the MR between inpatients ≥ 60 years of age and <60 years (MR=9% in age ≥ 60, P<0.001). MR was high among Caucasians (8.31%, P=0.021). There exists a small difference in the MR among hospital regions (highest in West at 8.36%, lowest in South 7.68%, p=0.001). There was no statistically significant difference in the MR among sex, emergency vs elective admissions. NRP was most commonly associated with secondary neoplasms, the prevalence in the order: secondary malignant neoplasm of bone (38%), liver and bile duct (26%), followed by lung (11%), peritoneum (10%), brain (9%). The encounter for palliative care was documented only in 8530 admissions (29%). Conclusions: MR is high on people with NRP who are ≥ 60 years, Caucasians. Regional difference also plays a role in this. Further studies are needed to address the causes of the difference. Utilization of palliative care service is found to be less in NRP admissions. Future admissions and mortality rates can be reduced by the effective utilization of palliative care, optimization of outpatient pain management.

Background: ASCO guidelines suggest patients > 65 should have a formal geriatric assessment [1]. We set up a new service in a London Cancer Centre. Cancer patients > 65 were reviewed in a one-stop GOLD clinic. Their focus was to provide a holistic approach to improve the oncology management. Nevertheless, not all cancer patients are fit to receive SACT. The aim of this study was to retrospectively review this group of patients. Methods: From October 2016 to April 2018, 596 patients were reviewed by GOLD. We analysed data for 298 (50%), including GOLD interventions and oncology management. In this cohort, 73% were between70-84 years (median 78). While most patients had SACT, 36 (12.4%) were deemed unfit by the oncology teams and had best supportive care only. These patients had a median age of 78.7 (64-93) and 20 (55.5%) were between 70-84. We also collected data on palliative care referral. Results: The main referrers were GI (10, 28%) and Urology (9, 25%). The rest included haematology (7, 19.4%), lung (5, 13.9%), gynaecology (3, 8.3%), melanoma and H&N (1, 2.8%) each. Referrals came mainly from the oncology teams (22, 61.1%). The remainder were identified from screening due to age (10, 27.8%) or following inpatient admission/Acute Oncology attendance (4, 11.1%). Co-morbidities and borderline performance status for systemic treatment were the two most common reasons for GOLD reviews (47.2% each), 8.3% involved polypharmacy and 2 (5.5%) cases involved social issues. Medication changes were advised for 52.8%. 41.6% did not have any changes to their management. One patient (2.8%) was referred to AHP and one (2.8%) to community palliative care. Fifteen (41.7%) had been referred to the Palliative Care team at the time of their review by GOLD. Conclusions: Despite multi-professional input, there are patients who remain unfit for SACT. It remains unclear whether a one-stop GOLD review added to the management of this group. Further evaluation is required to correctly identify patients who do not require multiple reviews.

Sin embargo, se observa una falta de competencias y alfabetización mediática sobre la correcta utilización de estas herramientas como componentes educativos.
SILIKON TERLARUT UNTUK PERTUMBUHAN DIATOM
Authors: Meirinawati Hanny
Published: November 2019

DISSOLVED SILICON FOR DIATOM GROWTH. Silicon is the second most abundant element in the earth’s crust. Silicon is an essential nutrient for diatom growth (Bacillariophyceae). Diatom require dissolved silicon to build silicate cell walls (frustule). Factors regulating diatom growth rate are cell size, concentration, heat, temperature, and concentration of Fe and Zn. The main source of dissolved silicon in the ocean is chemical weathering of rocks. The availability of dissolved silicon plays an important role in controlling the biogeochemical that regulates primary production, atmospheric CO, climate and ocean circulation. Changes in Si:N and Si:P ratios can affect the phytoplankton composition. Beside that, the function of silicon can reduce carbon dioxide levels from the atmosphere. This paper aims to provide information on the process of the occurrence of dissolved silicon in the sea and the function of dissolved silicon especially for diatom growth.

Published: November 2019

As abordagens ecossistêmicas surgem como enfoques alternativos que integram múltiplos aspectos para a compreensão e busca de soluções de problemas de saúde oriundos de precárias condições sociossanitárias. A vulnerabilidade para a leptospirose é marcada por áreas onde há propensão a ocorrer desastres naturais de alagamento associados a precárias condições sociossanitárias. O presente artigo traz a identificação de áreas de risco para leptospirose no município de Itaboraí considerando características ambientais e sociossanitárias relacionadas a produção da doença. A análise espacial foi realizada por meio de sobreposição dos temas de interesse: áreas de maior risco de inundação (28% do território), áreas críticas (0,9% do território e 9,3% da população do município) e casos notificados de leptospirose, através da análise visual. Dos 89 casos de leptospirose notificados, 71% foram localizados dentro das áreas de influência de inundação e 34% em localidades com precárias condições sociossanitárias. Os resultados alcançados com a integração das informações socioambientais do território e análise da distribuição espacial da leptospirose demonstra a ocorrência injusta, desproporcional e evitável de leptospirose naquelas localidades, ressaltando uma situação de iniquidade social em saúde na qual populações com menores condições econômicas são impelidas a ocupar porções do território ambientalmente degradadas e com menor disponibilidade de serviços. Essa se mostra uma promissora abordagem para a área da vigilância.
A REGIONALIZAÇÃO DA SAÚDE: O CAMINHO PARA O SUS EM TODOS OS TERRITÓRIOS?
Authors: Kadri Michele Rocha El
Published: November 2019

Em 2016, a Secretaria Estadual de Saúde do Amazonas convidou instituições públicas de diversos setores para contribuir com suas experiências descentralizadas no debate da regionalização. Em comum, a extensão territorial, a dispersão populacional e condições de acessibilidade foram os desafios destacados. Na saúde a proposição de uma alternativa que responda adequadamente as demandas do território e que ao mesmo tempo esteja em conformidade com as orientações nacionais, levantaram o debate sobre exequibilidade da regionalização tal qual planejada normativamente em um estado de características tão singulares. Neste texto, elegemos dois pressupostos que orientam a regionalização para debater a capacidade desse arranjo em de fato responder as necessidades do Estado do Amazonas: organização de regiões para garantir economia de escala e a continuidade do espaço geográfico entre municípios limítrofes. Apresentamos algumas proposições que estão a ser debatidas localmente e que precisam estar contempladas dentro do arranjo nacional de modo a contemplar a realidade local, ultrapassando o instituído hegemonicamente. A regionalização como toda estratégia é pensada em pequena escala, contudo para que de fato alcance seus objetivos num estado como o Amazonas é preciso aumentar escala para reconhecer detalhes locais e assim adotar alternativas de fato regionais.
SESERAHAN DALAM PERKAWINAN MASYARAKAT ADAT LAMPUNG
Authors: Nugroho Agung Tri
Published: November 2019

Delivery or delivery money is money given by the male to the prospective in-laws for marital needs with its positive and negative impacts. The negative impact of delivery money is seen when it is set at a high amount by the prospective in-laws to be paid, making it difficult to be met. Not a few also couples who want to establish a household are forced to postpone marriage because of the high amount of money that has been determined from the woman side. The research question in this paper is how the implementation of the practice of conducting delivery money in marriage customs in Lampung, is it true that the determination of very high sums of money influences the delay in marriage in the community and how the Islamic law views the delivery money which causes delays in marriage. By using field research methods, the data have been grouped into two forms, namely quantitative data and qualitative data. Quantitative data is the data of the results of the questionnaire while the qualitative data is the data of the results of interviews and observations. Then from the quantitative data tables are then analyzed and concluded while the qualitative data is connected between one fact and the other facts, then analyzed using a descriptive analysis approach. The results of the study found that the indigenous people of Lampung all practiced giving money and stipulated it by looking at the education of women, their work and the number of stipulated habits in the village, and eight pending marriages from several cases due to high cash, to the impacts arising from the stipulation of high and contradictory money with valid ‘urf terms; it can be concluded that the law of high passing money is not appropriate as it should apply. And many have charged men whose economies are middle to lower and who have dependents to carry out marriages resulting in delays in marriage.
Mega-Analysis of Gene Expression in Mouse Models of Alzheimer’s Disease

Published: November 2019

While multiple studies have been conducted of gene expression in mouse models of Alzheimer’s disease (AD), their findings have not reached a clear consensus and have not accounted for the potentially confounding effects of changes in cellular composition. To help address this gap, we conducted a re-analysis based meta-analysis (mega-analysis) of ten independent studies of hippocampal gene expression in mouse models of AD. We used estimates of cellular composition as covariates in statistical models aimed to identify genes differentially expressed (DE) at either early or late stages of progression. Our analysis revealed changes in gene expression at early phases shared across studies, including dysregulation of genes involved in cholesterol biosynthesis and the complement system. Expression changes at later stages were dominated by cellular compositional effects. Thus, despite the considerable heterogeneity of the mouse models, we identified common patterns that may contribute to our understanding of AD etiology. Our work also highlights the importance of controlling for cellular composition effects in genomics studies of neurodegeneration.
Environmental Enrichment Partially Repairs Subcortical Mapping Errors in Ten-m3 Knock-Out Mice during an Early Critical Period

Published: November 2019

Environmental enrichment (EE) has been shown to improve neural function via the regulation of cortical plasticity. Its capacity to induce functional and/or anatomical repair of miswired circuits is unknown. Ten-m3 knock-out (KO) mice exhibit a highly stereotyped and profound miswiring of ipsilateral retinogeniculate axons and associated deficits in binocularly-mediated visual behavior. We determined whether, and when, EE can drive the repair of subcortical wiring deficits by analyzing Ten-m3 KO and wild-type (WT) mice that were enriched for six weeks from adulthood, weaning or birth in comparison to standard-housed (SE) controls. Six weeks of EE initiated from birth, but not later, induced a significant reduction in the area occupied by ipsilateral retinogeniculate terminals in KOs. No EE-induced correction of mistargeted axons was observed at postnatal day (P)7, indicating that this intervention impacts pruning rather than initial targeting of axons. This reduction was most prominent in the ventrolateral region of the dorsal lateral geniculate nucleus (dLGN), suggesting a preferential pruning of the most profoundly mistargeted axons. EE can thus partially repair a specific, subcortical axonal wiring deficit, but only during an early, developmentally-restricted time window.

Published: November 2019

We investigate the dynamical behavior of a mathematical model of HIV and recombinant rabies virus (RV), designed to infect only the lymphocytes previously infected by HIV. This model is described by ﬁve ordinary diﬀerential equations with two discrete delays. The eﬀect of two time delays on stability of the equilibria of the system has been studied. Stability switches and Hopf bifurcations when time delays cross through some critical values are found. Numerical simulations are performed to illustrate the theoretical results.

Functional approach to analysis of daily tax revenues
Authors: Gudan Jovita , Račkauskas Alfredas
Published: November 2019

We present a functional data analysis approach to modeling and analyzing daily tax revenues. The main features of daily tax revenue we need to extract are some patterns within calendar months which can be used for prediction. As standard seasonal time series techniques cannot be used due to varying number of banking days per calendar month and presence of seasonality between and within months we interpret monthly tax revenues as curves obtained from daily data. Standard smoothing techniques and registration taking into account time variability are used for data preparation.

Revised linear convolution
Authors: Pupeikis Rimantas
Published: November 2019

It is assumed that linear time-invariant (LTI) system input signal samples are updated by a sensor in real time. It is urgent for every new input sample or for small part of new samples to update an ordinary convolution as well. The idea is that well-known convolution sum algorithm, used to calculate output signal, should not be recalculated with every new input sample. It is necessary just to modify the algorithm, when the new input sample renew the set of previous samples. Approaches in time and frequency domains are analyzed. An example of computation of the convolution in time area is presented.
Comparación de tecnologías para el tratamiento sostenible de aguas residuales ordinarias en pequeñas comunidades de Costa Rica
Authors: Centeno Mora Erick , Murillo Marín Adrián
Published: November 2019

Este artículo aborda el tema del tratamiento sostenible de las aguas residuales en pequeñas comunidades de Costa Rica. Aunque esfuerzos recientes muestran interés político en mejorar el rezago histórico que sufre el país en infraestructura sanitaria, existen pocas referencias que guíen el proceso de selección de la tecnología y escala más adecuadas para los sistemas a implantar. Este trabajo provee un análisis de tres tecnologías para plantas de tratamiento de aguas residuales (PTAR) de aplicación factible en el país. Para ello se estimó la demanda de área (DA), el costo constructivo (CC) y el costo de operación y mantenimiento (CO&M) de PTAR en diferentes escalas. Se mostró que los sistemas con humedal construido tienen la mayor DA y los menores CC y CO&M. Los sistemas con reactor anaerobio de flujo ascendente de manto de lodo seguido de filtro biológico percolador (UASB + FBP) tuvieron DA ligeramente mayores a las de los sistemas de lodos activados de aireación extendida (LAE), con CC ligeramente inferiores para la primera tecnología y CO&M de 50 a 100% mayores para los LAE. El estudio comprobó que la práctica actual de uso extendido de sistemas LAE en pequeña escala no resulta la opción más sostenible, por lo que se insta a que en el futuro se consideren escalas de PTAR mayores y se amplíe el abanico de tecnologías utilizadas en el país, aprovechando algunas recientes experiencias exitosas en países con condiciones similares.

Published: November 2019

The objective of this scientific article is to identify the relevant indicators to explain the shares price, considering the influence of two accounting moments. The Brazilian companies belonging to the food and beverage and paper and pulp sectors that provided information for the 60 quarters within the periods 2001-2007 and 2010-2016 were used. ARIMA or Box-Jenkins models and regression models with the use of dummy variables were applied. The authors express their preference for net profit and earnings per share to make predictions, the inclusion of yield on investment in this study offers a more reliable and comprehensive result because, unlike earnings, it represents the results of management on capital invested. The variables presented can be used to predict the shares price; the investment yield shows relevance over the rest of the variables in only one of the sectors studied. The change of period was found to have a significant impact on these results.RESUMENEl objetivo del artículo de investigación es identificar los indicadores relevantes para explicar el precio de acciones considerando la influencia de dos momentos contable.

CORPORATE SOCIAL RESPONSIBILITY, MULTINATIONAL COMPANIES AND ECONOMIC GLOBALIZATION
Authors: Dios Selma Alves , Cosenza José Paulo
Published: November 2019

This paper presents theoretical reflections whose purpose is to discuss the performance of Multinational Enterprises (MNEs) and the fact that the impacts of their activities are the result of their management, despite their focus on Corporate Social Responsibility (CSR). For this purpose, we reviewed some of the main CSR concepts and reference documents to identify in which way this type of organization could be contributing to global inequality. Additionally, we describe the characteristics of the general orientation of CSR in these companies. The main results indicate that when moving to less developed countries, MNEs take advantage of the existing unequal conditions of income and precariousness of labor and environmental rules. The construction of a favorable image through CSR contributes to MNEs success, but at the cost of a complex and intense process of concentration of wealth and deepening of social inequality and poverty.
O uso de técnicas de busca em vizinhança de grande porte para o problema de programação de máquinas paralelas
Authors: De Oliveira Ferreira Eduardo , Silva Gustavo Peixoto
Published: November 2019

Este trabalho trata do problema de sequenciamento de tarefas em máquinas paralelas e uniformes (parallel machines total weighted tardiness problem). O objetivo é sequenciar as tarefas tal que cada tarefa seja realizada em uma máquina, cada máquina realize uma tarefa por vez e seja minimizada a soma dos atrasos ponderados. O problema é resolvido em duas etapas: o particionamento das tarefas entre as máquinas e o sequenciamento das tarefas nas máquinas. A contribuição deste trabalho consiste em resolver as duas etapas com diferentes heurísticas de busca de grande porte e comparar suas eficiências. A técnica Very Large-scale Neighborhood Search, que utiliza um grafo de melhoria com cancelamento de ciclos negativos, é empregada para realizar o particionamento das tarefas. Um algoritmo de Programação Dinâmica, conhecido como Dynasearch, que também é uma técnica de busca em vizinhança de grande porte, realiza o sequenciamento das tarefas em cada máquina. Ambas as buscas são combinadas na metaheurística ILS. As duas versões do ILS são comparadas, resolvendo problemas benchmark da literatura.

Como resultado, evidenciou-se que somente para família alfa os métodos de combinação aumentaram a acuracidade. Porém, para as famílias beta e gama não foi observado melhorias na acurácia das previsões. Apesar disso, surge como oportunidade de pesquisa a integração de previsões via julgamento de especialistas.
Desperdício de Alimentos e Performance Logística: Uma Análise do Cenário Brasileiro
Authors: Abbade Eduardo Botti
Published: November 2019

Este estudo tem como objetivo analisar os níveis de perda alimentar de grupos específicos de alimentos destinados ao suprimento alimentar nacional, confrontando tal problemática com a performance logística do Brasil. Além disso, o estudo se propõe a conduzir uma discussão acerca da problemática nacional e mundial que permeia a questão do desperdício alimentar e suas implicações econômicas, sociais e ambientais. Para tanto, a investigação considerou dados anuais disponibilizados pela FAO referentes ao suprimento doméstico e às perdas de alimentos de 7 grupos específicos de alimentos. Também foram considerados os dados disponibilizados pelo Banco Mundial referente à avaliação do LPI (Logistics Performance Index) e suas 6 dimensões. Os resultados sugerem que a avaliação da performance logística do Brasil apresenta melhorias, principalmente na dimensão “Monitoramento e rastreio”. No geral, a performance logística do país é mediana. O estudo sugere também que os maiores níveis de perda de alimentos em relação ao suprimento são as perdas de frutas, seguido de perdas de cereais, vegetais e raízes. A discussão apresentada enfatiza a problemática do desperdício alimentar e suas implicações na promoção da segurança alimentar e objetivos do desenvolvimento sustentável.

Qualquer processo, seja ele produtivo ou não, é suscetível a falhas e estas podem gerar consequências nos produtos finais. Na indústria farmacêutica veterinária a gestão destas falhas, além de ser uma das demandas do sistema de qualidade, é uma necessidade legal, verificada por auditorias de agências regulatórias. Assim, a gestão das não conformidades apresenta grande importância para melhoria contínua. Atrelado a isso, verifica-se nos últimos anos a tendência de aumento da prática de terceirização da produção de medicamentos veterinários em vista das vantagens financeiras envolvidas. Com essa mudança no processo produtivo, identificam-se dificuldades relacionadas à avaliação do impacto financeiro destes desvios para as empresas contratantes. Em vista disso, este trabalho, por meio de um estudo de caso, teve como objetivo o levantamento de desvios de manufatura, suas causas raiz e ações corretivas determinadas pela empresa terceira, e os custos envolvidos com essas falhas para a empresa contratante. Com essas informações verificou-se oportunidades de melhorias do processo, visando destinar investimentos de forma mais assertiva.
CAUSES AND RESULTS OF DRUG INTOXICATION IN PREGNANCY.
Authors: YUKSEK Ahmet , TALİH Gamze
Published: November 2019

Background
and aim: Pharmacokinetics and pharmacodynamics of drugs may
vary in pregnancy1.Therefore, these patients are usually followed up
in intensive care.Although early-term complications due to intoxication are
usually a challenge for the physician in the intensive care unit, late-term
effects are unknown by intensivists and
only followed by a gynecologist2,3.
In our study, commonly used drugs and complications related to intoxication
were investigated.Methods:
In
the last 5 years, pregnant patients who admitted to our hospital with drug
intoxication were evaluated retrospectively.The hospital archives were
investigated in these patients for the mortality and morbidity due to
intoxication, in the pregnancy period, the postnatal first month and the
effects on the newborn.Result:
Seventy
five percentof 116 pregnant women who admitted to our hospital due to drug
intoxication were followed up in the intensive
care unit.According to the consultation
notes, 47.4%of the patients were useddrugs
for the purpose of suicide and the 52.58% patientswere used inadvertently.The most commonly used drugs were prenatal
vitamin drugs(%28.4), paracetamol (21.5%), antibiotics (%12) and non-opioid
analgesics 6.8%, There was more than one drug use in 28 patients. Fifteen of
the patients were referred to another center. Five patients had premature labor
or miscarriage.In 2 patients, the condition was mortal.

Conclusion:
Drug
intoxications in pregnant women are usually carried out by the drugs they
use.The mortality rate was found to be low because the therapeutic ranges of
these drugs were broad4Pregnancy is a long process and it may be
difficult to establish a relationship between possible complications and drug
intoxication during pregnancy.Therefore the true morbidity rate is not clear.

Associations between the Mixture of Governance Modes and the Performance of Local Public Service Delivery
Authors: Swe Yin Lei Win , Lim Seunghoo
Published: November 2019

Since the Myanmar central government decentralized some of its power to state and regional governments, few studies investigated the performance of local governments, and no studies investigated the relationships between the types of governance modes and the performance of public service delivery. This study investigates the associations between three types of governance—i.e., hierarchy, market, and network—and the multiple performances of agricultural services in terms of the competing public values of efficiency, effectiveness and equity in southern Shan State. The findings indicate that the three types of governance simultaneously coexist in local agriculture departments and that their associations with the performances of public services differ. Network governance is negatively associated with efficiency, effectiveness, and equity during its initial stage, but these associations become positive when the degree of network governance increases in agriculture departments. In contrast, market governance is positively related to effectiveness and equity during its initial stage; however, increasing the degree of market governance further leads to a negative association with both public service values. This assessment of the performance of public programmes in terms of the trade-offs among public service values contributes to improving the local governance of public service delivery not only in Myanmar but also in other developing countries.

Snakeskin gourami (Trichogaster pectoralis) is a freshwater fish often consumed by the people of South Kalimantan. The meat and the bones of this fish can be processed into protein and calcium-rich fish sticks. This study was aimed to analyze the sensory and chemical characteristics of snakeskin gourami stick. The meat and bones of the fish were added into sticks ingredients with the proportion of 0; 20; 40 and 60%. The results showed that the addition of fish meat and bones significantly affected the sensory characteristics particularly on the aroma and the taste of fish sticks, as well as the chemical quality including protein, fat, carbohydrate, water, ash, and calcium content. The sticks made with 60% of the fish meat and bones were more preferred and gave better chemical characteristics than those made with the other proportions.

Mechanical property is important factors in determining quality of surimi-based products. Plant phenolic compound has been used to improve mechanical properties of surimi gel. The aim of this study was to determine the effects of addition of olive leaf extract powder (OLEP) on the mechanical properties of surimi gel. Addition of OLEP that contained polyphenol of 1.9 mg GAE/g dry weight to surimi increased breaking stress and breaking strain of surimi gel. The breaking stress and breaking strain of surimi gel increased with increasing OLEP concentration. The addition of 0.2% OLEP increased the breaking stress of surimi gel by 13% and the breaking strain by 27%. The addition of 0.5% OLEP resulted in a 1.2 times increase in the breaking stress and breaking strain of surimi gel. Increasing breaking stress and breaking strain of surimi gel with the addition of OLEP is caused by the integration of additional crosslinks into the protein networks via polyphenols or their derivatives. Although the addition of OLEP had a detrimental effect on whiteness of surimi gel, OLEP is still a useful functional ingredient for improving mechanical properties of surimi gel products in which the color is not an important quality.
