ABSTRACT Objectives: to indentify the time trend of rates of organs and tissues effective donors, of reports and types of transplanted organs per million people of the Brazilian population. Methods: ecological study, of time series, about reports of organ donations and on transplants. The data were provided by the Registro Brasileiro de Transplantes and analyzed using polynomial regression. Results an increasing trend was found for potential donors and effective donors, with an average increase of 2.33 and 0.92 per year, respectively. The South Region had the highest rate of potential donors (83.8) and effective donors (34.1) and the North Region, the lowest rate (20.2 and 3.9). The family refusal was the main obstacle to accomplish the donation. Conclusions the results show an increasing trend of potential donors and effective donors throughout Brazil, with emphasis on the southern region of the country. Among the main reasons for non-donation, it is worth emphasizing family refusal and medical contraindication prescription.

Published: March 2021

ABSTRACT Objective: To analyze potential triggers of moral suffering experiences of health professionals, reported in the media, during the COVID-19 pandemic and to propose a theoretical construct of analysis. Methods: Study with qualitative approach whose data source were 50 reports published online, collected passively and actively, submitted to Content Analysis with the help of ATLAS.ti software. Results: The potential moral problems that trigger moral suffering are related to the threat to moral integrity, infrastructure/logistics and teamwork problems, and emotional aspects, revealing their articulation with damage to the foundations of a healthy work environment, which generated the proposal of a construct. Final considerations: The articulation between the experiences of moral suffering and the commitment of the fundamentals of a healthy work environment has brought important contributions to the adoption of strategies to protect and stimulate moral deliberation by professionals in favor of practice and society.
COVID-19 monetary transfer in El Salvador: determining factors
Authors: Durán Carlos Ayala
Published: March 2021

Abstract Given the lack of governmental guidelines, this paper identifies and analyzes the statistical determinants associated with receiving the onetime monetary transfer in El Salvador ($300 dollars) as an economic measure to face the COVID-19 pandemic. A logistic regression was implemented (whether received the transfer or not) based on a probabilistic sample (n=1222) of surveyed people throughout the country. Independent variables were selected drawing upon key characteristics employed internationally in monetary transfers: age, gender, rural area, employment, family income, and education. The text identifies a statistically significant and negative relation between receiving the monetary transfer and two variables: family income and educational level. The need to increase coverage of the program is addressed as well as the importance of considering age, gender, rural areas, and employment as criteria for selecting the beneficiaries in such economic measures.
How many could have been saved? Effects of social distancing on COVID-19
Authors: Cunha Matheus , Domingos Amanda , Rocha Virginia , Torres Marcus
Published: March 2021

Abstract What is the effect of social distancing policies on the spread of the new coronavirus? Social distancing policies rose to prominence as most capable of containing contagion and saving lives. Our purpose in this paper is to identify the causal effect of social distancing policies on the number of confirmed cases of COVID-19 and on contagion velocity. We align our main argument with the existing scientific consensus: social distancing policies negatively affect the number of cases. To test this hypothesis, we construct a dataset with daily information on 78 affected countries in the world. We compute several relevant measures from publicly available information on the number of cases and deaths to estimate causal effects for short-term and cumulative effects of social distancing policies. We use a time-series cross-sectional matching approach to match countries’ observable histories. Causal effects (ATTs and ATEs) can be extracted via a dif-in-dif estimator. Results show that social distancing policies reduce the aggregated number of cases by 4,832 on average (or 17.5/100 thousand), but only when strict measures are adopted. This effect seems to manifest from the third week onwards.
The hydroxychloroquine alliance: how far-right leaders and alt-science preachers came together to promote a miracle drug
Authors: Casarões Guilherme , Magalhães David
Published: March 2021

Abstract Soon after the outbreak of the COVID-19 pandemic, the world saw far-right leaders uniting to promote hydroxychloroquine despite controversial results. Why have some leaders actively promoted the drug since then, contradicting recommendations made by their own government’s health authorities? Our argument is twofold. First, hydroxychloroquine has been an integral tool of medical populist performance in the context of the COVID-19 pandemic. We adopt Lasco & Curato’s (2018) definition of medical populism as a political style based on performances of public health crises that pit ‘the people’ against ‘the establishment’ using alternative knowledge claims to cast doubt on the credibility of doctors, scientists, and technocrats. Second, rather than being an individual endeavor, medical populism addressing the coronavirus crisis has led populists to build an alt-science network. We define it as a loose movement of alleged truth-seekers who publicly advance scientific claims at a crossroads between partial evidence, pseudo-science, and conspiracy theories. It comprises scientists, businesspeople and celebrities united by their distrust of governments and mainstream science. In this article, we look at how the hydroxychloroquine alliance was formed, as well as its political and policy implications. To this end, we compare why and how Donald Trump and Jair Bolsonaro have appealed to medical populist performances when addressing the health crisis. By mobilizing the concepts of medical populism and alt-science, this paper aims to contribute to the scholarship on the relationship between populist politics and policy-making.
“BOTA FOGO NESSES VAGABUNDOS!”: ENTEXTUALIZAÇÕES DE XENOFOBIA NA TRAJETÓRIA TEXTUAL DE UMA FAKE NEWS
Authors: Silva Izabel da
Published: March 2021

RESUMO Com a emergência da internet como infraestrutura de inovação nos modos de comunicação, a produção de fake news cresceu em profusão, facilitando os modos de publicação e o compartilhamento de informações e notícias falsas. As fake news têm extrapolado a materialidade dos textos e potencializado discursos de ódio na sociedade e violações aos direitos humanos, a exemplo de ataques xenofóbicos a imigrantes no país. Afiliado à vertente indisciplinar da Linguística Aplicada (Moita Lopes, 2006; Cavalcanti, 2013), este estudo de base qualitativo-interpretativista busca analisar que entextualizações foram mobilizadas na trajetória textual de uma fake news em diferentes plataformas digitais e que posicionamentos os participantes da interação assumem em relação à situação da migração de crise no país. O corpus recobre a trajetória textual do evento ‘Bota fogo!’, referente ao ataque a imigrantes venezuelanos em Pacaraima, ocorrido em 18 de agosto de 2018. Os resultados indicam que a propagação de fake news mobiliza posicionamentos discursivo-identitários preconceituosos em interações virtuais, e, além disso, impulsionam reações xenofóbicas fora das redes online.
WHEN THE CHECKPOINT BECOMES A COUNTERPOINT: STASIS AS QUEER DISSENT
Authors: Milani Tommaso M. , Awayed-Bishara Muzna , Gafter Roey J. , Levon Erez
Published: March 2021

ABSTRACT This article was born out of a sense of discomfort with the privilege accorded to movement and mobility in critical scholarship in the social sciences and the humanities, including critical work on the relationship between language, sexuality and space. It is our contention in this article that stasis can be deployed as a radical practice of defiance, and therefore can be queer too. In order to argue that stillness can be a form of social action carrying the potential of forging a radical politics of dissent, we take as a case in point the checkpoint in the context of Israel/Palestine. Drawing upon Said’s (1984, 1994) notion of the counterpoint and Stroud’s (2018) theorisation of linguistic citizenship, we illustrate how the checkpoint can become a bodily, discursive and material counterpoint that activates the irreconcilable tensions between utopia and dystopia in the pursuit of “thorough resistance to regimes of the normal” (WARNER, 1993, p. xxvi).
MIGRANT YOUTH PUSH BACK. VIRTUAL FRIENDSHIPS AND EVERYDAY RESISTANCE IN THE DIGITAL SPHERE
Authors: Fina Anna De
Published: March 2021

ABSTRACT Resistance has proven to be a hard concept to define. Debates about resistance in the sociological and sociolinguistic literature cover many aspects: from the degree to which resistance can be seen as related to established social groups (see Rampton 1996), to the level of agentivity and intention that is required for an action to be regarded as resistant, to the type of social behavior that qualifies. Thus, while some see resistance as based on actions, others see it as based on cultural appropriation (Hall & Jefferson 1976). In their comprehensive review of literature on the topic, Hollander & Einwohner (2004) conclude that resistance can be seen as consisting of action and opposition. In this paper, I analyze resistance from the point of view of opposition to ideas, social situations, institutional actions and processes that result or may result in discrimination or stereotyping of specific social groups, as negotiated in the digital sphere by migrant and non-migrant youth belonging to a school-based community. Indeed, it has been argued (Chiluwa 2012, Chibuwe & Ureke 2016) that digital environments constitute ideal arenas for the development of resistance thanks to their wide reach and their ability to mobilize people around common themes. However, much of the research in this area has targeted organized resistance fueled by political or ethnic groups. In this paper I argue that resistance is an emerging process that does not necessarily stem within political contexts or from open choice, but can develop within interactional exchanges focused on everyday life events. Thus, what I am interested in here is in how spontaneous acts and discourses of resistance emerge in the everyday exchanges of a diverse community that was not born around a particular social or political agenda. For this paper, I will examine exchanges that happen on the Facebook page of one of the members of the community. I will show how resistance takes many forms: from irony and jokes to the raising of serious topics, to the dissemination of information and through different discourse genres: from storytelling to the posting of pictures.
Fenômenos estocásticos em migração celular: teoria, experimentos e simulações
Authors: de Almeida Rita M.C.
Published: March 2021

Migração celular é um ingrediente importante no desenvolvimento de seres multicelulares e em processos como resposta imunológica ou metástases em câncer. Apresentamos uma revisão sobre modelagem de migração celular de célula isolada sobre substratos planos. Reanálise de dados experimentais mostraram um comportamento que se desvia do modelo canônico, o modelo de Langevin para uma partícula com um movimento Browniano. A proposição de um modelo semiempírico que prevê um comportamento difusivo em escalas de tempo muito curtas, ajusta os dados experimentais mas coloca em cheque a definição usual de velocidade e o correspondente protocolo de medidas. A solução é apresentada sob a forma de um modelo anisotrópico para a migração celular com uma variável interna representando a quebra de simetria espacial da célula em migração. A previsão teórica possibilita a definição de unidades naturais do sistema que resultam no colapso de curvas teóricas e experimentais em uma família de curvas com um só parâmetro. Adicionalmente, discutimos um modelo de simulações para células em três dimensões, que foi validado por comparações quantitativas com dados experimentais, possibilitadas pelo modelo teórico proposto. Estes resultados podem agora ser aplicados para situações mais complexas, que implicam em interações não lineares e requerem soluções numéricas.

Published: March 2021

ABSTRACT The objective of this study was to understand how the shares’ volatility affects the portfolios’ dynamics formed using the model of pairs trading in the Brazilian stock market. This article distinguished itself by bringing new evidence about the effects of volatility in the pairs trading model not covered by previous studies, expanding the sample size analyzed in the Brazilian stock market. The chosen theme’s relevance is that investors can use pairs trading or long-short models to build their portfolios. The use of cointegration concepts probabilistically contributes to portfolios’ formation weakly correlated to the market indexes with superior performance. This article impacts the area by contributing new evidence for better use of the model in the analysis of investments. From January 2016 to December 2018, the 90 most liquid assets of Bolsa, Brasil, Balcão (B3) were analyzed, totaling 5,927,400 possible pairs. The Augmented Dickey-Fuller test and subsequent backtesting of the pairs in the proposed period were used to evaluate the cointegration criteria. Statistical analysis was performed by parametric and non-parametric tests and Pearson and Spearman correlation analyses. The results found indicated that the formation of portfolios by pairs trading with dependent assets with the criterion of higher levels of volatility (20 periods) presented a superior performance. These findings can be justified by a better risk and return ratio for the portfolio, measured by the Sharpe Index of the returns obtained concerning the portfolio’s volatility, compared to a portfolio formation based on a random selection of the pairs. In addition, the results also showed a low correlation of returns concerning the market index. Therefore, the application of the statistical cointegration analysis methodology alone does not guarantee results that are different from the market average.

Abstract: Introduction: The limits of the Community Health (CH) course load (CL) before medical clerkship (MC) in undergraduate medical courses are not defined neither in the National Curriculum Guidelines nor in other documents, and have not been investigated in a comprehensive way in national studies. Objective: To analyze the community health course load before clerkship in Brazilian medical schools. Method: Cross-sectional study of schools acknowledged by the Ministry of Education, which started activities until December 31, 2017. The sites of the 323 existing schools were accessed and the schools that had their curricula available in the internet with details of the CH CL before MC were included. The variables were school geographic region and administration type, medical course CL and CH CL before MC, also including epidemiology, biostatistics and occupational health course loads. Data were analyzed using descriptive statistics, Pearson chi-square (Ӽ2) for categorical variables and Mann-Whitney-U (U) and Kruskal Wallis Ӽ2 tests for continuous variables. Results: Out of 323 existing medical schools, 222 were included (68.7%). Among the included schools, 83 were tuition-free (37.4%) and 139 were not (62.6%). The median of the CH CL before MC was 440.0 hours (P25-75 = 300.0 - 640.0), equivalent to 5.4% (P25-75 = 3.5 - 7.8) of the medical course CL. The median of the CH CL before MC in hours in private and municipal schools was, respectively, 480.0 (P25-75 = 330.7 - 679.2) and 576.0 (P25-75 = 360.0 - 766.0), and of state and federal schools, respectively, 337.0 (P25-75 = 281.2 - 524.2) and 370.0 (P25-75 = 300.0 - 480.0), Ӽ2(3) = 11.48, p = .009. The median of the total CH CL in non-tuition-free schools was 500.0 hours (P25-75 = 336.0 - 690.0) and in the tuition-free schools, it was 364.0 hours (P25-75 = 285.0 - 504.0), U = 4.259.0, z = -3.26, p = .001. The median of epidemiology and biostatistics CL in hours before MC in the 124 schools was 88.0 (P25-75 = 60.0 - 120.0), whereas the occupational health CL in 63 schools was 40.0 (P25-75 = 33.0 - 60.0). Conclusions: The CH CL before clerkship varies widely, being higher in non-tuition-free medical schools.

Salah satu produk unggulan Kabupaten Subang di bidang hortikultura dan komoditas utamanya adalah buah nanas. Hasil panen buah nanas di Kabupaten Subang sangat banyak, namun belum termanfaatkan secara maksimal. Untuk memanfaatkan hasil panen buah nanas secara maksimal, maka buah nanas perlu diolah menjadi sebuah produk yang inovatif yaitu dengan mengolahnya menjadi saus nanas. Saus nanas bisa dijadikan sebagai alternatif oleh-oleh khas Subang, namun umur simpan saus nanas hanya bertahan dalam waktu yang relatif singkat yaitu sekitar 7-10 hari, maka dari itu perlu upaya untuk membuat umur simpan saus nanas agar lebih tahan lama yaitu dengan cara pengawetan. Tujuan dari penelitian ini adalah menentukan metode mengawetkan saus nanas yang paling efektif, mengetahui umur simpan saus nanas, dan menganalisis daya terima saus nanas pada masyarakat. Metode penelitian yang digunakan pada penelitian ini adalah eksperimental yaitu dengan memperbaiki langkah pembuatan saus nanas yang pada awalnya potongan buah nanas ditambahkan pada 5-10 menit terkahir sebelum saus nanas matang, kemudian diubah dengan memasukan potongan nanas saat saus nanas mulai mendidih. Setelah saus nanas matang dilakukan pengecekan pH, kemudian ditambahkan pengawet berupa natrium benzoat dengan takaran 500 mg/Kg saus nanas. Selanjutnya diuji masa simpannya di lab dan dihasilkan masa simpan saus nanas selama 7 bulan 1 hari. Saus nanas dengan penambahan natrium benzoat dapat diterima dan disukai oleh masyarakat.

Investigation of the Adequacy of Bridge Design Loads in Pakistan
Authors: Shahid I , Noman A. K. , Farooq S. H. , Arshad Ali
Published: March 2021

Weight, configuration, and volume of traffic vary from country to country. But, in developing countries like Pakistan, bridges are designed based on codes of developed countries. Hence, these bridges may not have desired safety level. In this study, safety levels of three sample bridges has been investigated in terms of structural reliability index.  Live load effects (shear and moments) in girders were determined using weigh-in-motion data (WIM) and were extrapolated to 75 years using non-parametric fit. Two live load models and two strengths, required by 1967 Pakistan Code of Practice for Highway Bridges (PHB Design-Case) and that required by the 2012 AASHTO LRFD Bridge Design Specifications (AASHTO Design-Case) were used in reliability analysis. It is found that actual trucks produce moment and shear in girders 11 to 45 percent higher than live load models of PHB and AASHTO design cases. Values of structural reliability indices vary from 1.25 to 2.50 and from 2.45 to 3.15 for PHB and AASHTO design cases, respectively, and are less than the target reliability index value of 3.50 used in the design codes as benchmark.  It is revealed after the research that bridges in Pakistan may not have desired safety level, and current live load models may not be the true representation of service-level truck traffic.

Used frying oil (UFO) has a great potential as feedstock for biodiesel production. This study aims to develop an artificial neural  network  (ANN)  model  to  predict  biodiesel  yield produced from base-catalyzed transesterification of UFO. The experiment  was  performed  with  100  mL  of  UFO  at  three different  molar  ratios  (oil:methanol) (namely 1:4,  1:5,  and 1:6), conducted with reaction temperatures of  30 to 55oC (raised by 5oC), and reaction time of 0.25, 0.5, 1, 2, 3, 6, 8, and 10 minutes. Prediction model was based on ANN model consisting  of  three  layers  with  27  combinations  of  three activation  functions  (tansig,  logsig,  purelin).  All  activation function  architectures  were  trained  using  Levenberg- Marquardt train type with 126 data set (87.5%) and learning rate  of  0.001.  Model  validation  used  18  data  set  (12.5%) measured at reaction time of 8 min. Results showed that two ANN models with activation function of logsig-purelin-logsig and purelin-logsig-tansig be the best with RRMSE of 2.41% and  2.44%  with  R2  of  0.9355  and  0.9391,  respectively. Predictions   of   biodiesel   yield   using   ANN   models   are significantly better than those of first-order kinetics.
Trends in Expert System Development: A Practicum Content Analysis in Vocational Education for Over Grow Pandemic Learning Problems
Authors: Ana Ana
Published: March 2021

The impact of the COVID-19 has emerged as a varied issue, ranging from the economy, society's social order, and edu­cation, especially when social and physical distancing have been introduced in various areas of community activities as one of the prevention. It has also affected the tertiary edu­cation institution where learning activities should be con­ducted from and at home, forcing the higher education communities to shift learning from conventional learning to online learning. Needless to say, learning that does not re­quire practicum is easier compared to learning that needs it. Consequently, it is a new task for lecturers to ensure the meaningful practicum learning implementation is con­ducted as it should be. Therefore, the creation of expert systems for practicum learning in vocational education is urgently required in online learning. The aim of this litera­ture review was to examine the development of an expert system used at practicum learning in tertiary institutions and how the design of learning systems could be integrated into vocational education in facing the COVID-19 pandemic. The method used was the literature study, through research stages starting from the finding and selection of articles and journals with relevant topics, and then analysing the data. The findings of this study was to identify the development of an expert program in an attempt to promote practicum learning using e-learning in the midst of the COVID-19 pan­demic outbreak.

Published: March 2021

This paper exhibits a method to predict the remaining service lifetime of inflatable rubber dam by considering the appearance of deep hole damage. The material used for the rubber dam is a composite comprising three layers of woven fabric as fiber and EPDM/SBR 64 474 rubber as a matrix. The service lifetime is predicted by calculating the degradation of rubber dam’s material properties. Simple Rate Law model and Time-Temperature Superposition model are employed to calculate the rubber properties degradation. A finite element analysis is then conducted to investigate stress and strain distributions which occur in the rubber dam membrane during operational loading. Furthermore, the effect of deep hole damage in the rubber dam, which is caused by improper maintenance, is modeled as well. The results show that a 7 mm depth of the hole can accelerate rubber degradation, which causes catastrophic failure. This can happen because two layers of the woven fabric in the rubber dam have been broken. Suggestion to hold up the degradation is also discussed.

Authors: Satriawan Muhammad , Liliasari L , Setiawan Wawan , Abdullah Ade Gafar
Published: March 2021

This paper aims to review the potential of wave energy in several countries, the wave energy converter technology that has been developed, and the impact of the installation of wave energy converter technology devices on the environment. In addition, it discusses the theoretical formulations and challenges in the development of energy converter technology in the future. Based on the detail analysis, the potential of ocean wave energy for alternative energy is very large but cannot be used optimally because the technology of wave energy converter that has been developed is still on a prototype scale. In addition, the impact of the use of ocean wave converters on the environment is insignificant compared with conventional energy. Finally, this study informs and recommends the government and the private sector to start investing in the ocean wave energy industry optimally in order to achieve a sustainable future.

Published: March 2021

Adsorption isotherm is the most important calculation to predict and analyze the various possible mechanisms that occur in adsorption process. However, until now, most studies only presented the adsorption isotherm theory, and there are no studies that explain the adsorption isotherm thoroughly and in detail from theory to calculation. Therefore, this study contains guidelines for selecting the type of adsorption isotherm to describe the entire adsorption data set, which is featured by the ten most common adsorption isotherms. The steps of how to analyze the two-parameter monolayer adsorption are presented. This study is expected to provide clear and useful information for researchers who are working and studying on the adsorption process.

Published: March 2021

En este artículo se presentan los resultados de un primer análisis cualitativo sobre las principales manifestaciones de la polifonía en un corpus de Columnas sobre la lengua (CSL) publicadas en la prensa española entre 1959 y 2019. El análisis, basado en los principales planteamientos de la teoría polifónica, tiene como objetivos, en primer lugar, identificar las marcas polifónicas que aparecen en artículos de opinión en los que sus autores describen y evalúan determinados usos lingüísticos del español; y en segundo lugar, determinar las funciones discursivas que desempeñan los enunciados polifónicos en estos textos. Los resultados de este análisis muestran que los autores de las CSL analizadas combinan diversos dispositivos de reproducción del discurso, como la cita directa e indirecta, el perspectivismo dialógico, los enunciados interrogativos y la ironía verbal, que los autores emplean con fines argumentativos y persuasivos para evaluar los usos lingüísticos de determinados hablantes y establecer una relación de complicidad con el lector.
An Unexpected Fraternity: An Approach to Holocaust Memoirs in English Through Animal Metaphorization
Authors: Miñano Mañero Laura
Published: March 2021

This paper examines autobiographical texts written by Nazi concentration camp survivors to explore the authors’ metaphorization of animals as a means of conveying their own suffering. The authors whose memoirs are analyzed migrated to America after the war, and significantly chose to pen their traumatic experience in English, which must have been a challenging endeavor for them as non-native speakers. Since academic discussion on the Holocaust is mainly conducted in an Anglophone framework, it is vital that we pay attention to English-language memoirs, and listen to the survivors’ genuine words, rather than merely relying on translations. I suggest that animal metaphorization allows them to overcome in some way the ineffability inherent to all Holocaust memoirs. Moreover, by exploring animal images it is possible to inquire about their personal attitudes regarding other species, as authors often sympathize with –and relate to– animal suffering. My main goal is thus to decide whether this rhetorical resource points at the emergence of an interspecies empathy, based on the shared ability to feel pain and, as sentient beings, to suffer.

Lack of several vitamins, calcium, magnesium, zinc, iodine and other minerals in the diet now is typical for the majority of the adult and childrens population of Russia, regardless of where they live, throughout the year. In addition, population groups that are additionally at risk of developing micronutrient deficiencies exist. Children 23 years old when switching to food from a common table, early puberty, pregnant and lactating women, persons with food intolerances and allergies, persons on elimination diets (vegetarians, vegans, etc.), or enriching the diet with dietary fiber, obese persons (reduced by caloric content of the diet), persons with gastrointestinal diseases (sparing diets, persons receiving drug therapy, persons with increased physical and psycho-emotional stress, the elderly, persons observing long-term religious fasts, athletes controlling body weight are among them. The role of each micronutrient depends on the sufficiency of the body with other micronutrients involved in the metabolism or necessary for the realization of the final function in the body. A recognized and scientifically grounded way to improve micronutrient status is the enrichment of the diet with vitamins and minerals. In the absence of mandatory fortification of mass-market foods the use of vitamin and mineral supplements is a great idea. The selection criterion is a complete set of vitamins and microelements, the deficiency of which is characteristic for a particular group of the population, and in doses close to the physiological needs of the body.

The article discusses topical issues reflecting the high prevalence of diabetes mellitus (DM), the continuing trend towards an increase in the number of patients, the high incidence of vascular complications that lead to early disability and high mortality. The review presents current data on the role of oxidative stress in the development and progression of vascular complications in patients with type 2 diabetes, as well as the mechanisms underlying the imbalance between prooxidants and the antioxidant defense system in this disease. The article presents the role of a balanced diet in achieving metabolic goals and increasing antioxidant protection in type 2 diabetes. The review provides data on the role of vitamins in the correction of metabolic disorders in type 2 diabetes. The increased need for antioxidant vitamins in diabetes is due to impaired glucose metabolism in this category of patients. Food products, which contain polyphenolic compounds, have a pronounced antioxidant and antithrombotic activity, which favorably affect metabolic parameters that contribute to weight loss. Thus, one of the ways to optimize the therapeutic nutrition of patients with type 2 diabetes is the inclusion in the standard hypocaloric diet of specialized food products containing antioxidant vitamins and minor biologically active substances with pronounced antioxidant properties.

Relevance, material and methods. Purpose of the work: comparative assessment of the content of the sum of phenolic compounds exhibiting antioxidant activity in various organs of herbaceous capers C. herbacea Willd. The 4 samples of C. herbaceawere collected from natural populations of Dagestan during the flowering and fruiting phases in the summer of 2019. The collected raw materials were divided into fractions (organs), dried in the shade to an air-dry mass, then subjected to further analysis to determine the total content of flavonoids, anthocyanins by the spertrophotometric method on SF-56; the total content of antioxidants by the amperometric method on the instrument of express analysis "Color-Yauza-001-AAA ".

Results. During the analysis, good indicators were obtained for the content of the studied compounds. Thus, in terms of the content of flavonoids, the greatest variation is seen in the stems of herbaceous capers (0.34-0.86%) compared to their content in leaves and inflorescences (2.67-2.97% and 2.45-2.90%, respectively). The amount of anthocyanins varies in all organs within the range of 0.05-0.23%. The smallest spread is observed in the total content of antioxidants in the fruits of herbaceous capers (21.35-21.40 mg/l), while in inflorescences this indicator varies greatly (27.44-42.19 mg/l). It is noteworthy that the samples with a high value of antioxidants showed a low content of flavonoids, thereby indicating that flavonoids are not the main components in the antioxidant system of the studied caper species. An important condition determining the variability of the content of phenolic compounds in various plant organs is a complex of abiotic environmental factors. The study of this factor (altitude gradient) revealed a significant relationship with the accumulation of flavonoids in all organs, which has a multi-vector nature (correlation coefficient r*= 0.57; 0.56; -0.47), respectively, in stems, leaves, and inflorescences (P<0,05). A positive relationship in the accumulation of anthocyanins is observed with the height in caper leaves. In all other cases, the connection is random. In addition, the analysis of variance revealed that a large difference in the variability of the studied compounds is observed between individual groups of plants in the absence of intragroup variability.

Relevance. Oxidative reactions (based on peroxidase activity, POX and polyphenol oxidase, PPO; hydrogen peroxide content) that occur in response to infection or reinfection of the off-spring of infected plants depend on the type of host-virus interaction (sensitive, tolerant, stable) and the nature of the interaction with viral infection (primary infection, reinfection of second and third generations).

Results. Reinfection with tomato aspermy virus (TАV) or tobacco mosaic virus (TMV) of the off-spring of third infected tomato generation caused a significant decrease in POX activity compared to successive generations of infected plants (G2) for Craigella (Tm-22/Tm- 22) and S. pimpinellifolium genotypes or an increase for Rufina and Craigella (Tm-1/Tm-1) ones. In genotypes containing resistance genes, Rufina and Craigella, no differences were observed in PPO of TMV primary infection and control, while significant differences were found in case of TAV (susceptibility). As a result of TMV infection, the sensitive (Elvira) and tolerant (S. pimpinellifolium) genotypes showed an increase in PPO values compared to the control. At the same time, in most genotypes primarily / secondarily infected with TAV or TMV, statistically significant differences were revealed in the activity of POX or PPO, as well as the accumulation of hydrogen peroxide in plant leaves, which indicates specific protective reactions of the genotypes.

Relevance.In accordance with the needs of the market, in 2008, a variety of zucchini Russian spaghetti with two-colored fruits was created. We faced difficulties in maintaining a high percentage of two-color forms in the variety population. To solve this problem, we studied the possibility of using markers of young zucchini leaves in the selection of forms with different fruit colors in technical ripeness.

Material and conditions. The experience was started in 2005 to 2018 in the open ground on the basis of FSBSI FSVC. In the breeding nursery, research was conducted annually on 30 plants. The color of the fruit was taken into account only in the phase of technical ripeness. The best plants were propagated by incest. In the nursery breeding varieties of Russian spaghetti were sown by family. During 4 years in each family, at different stages of development, 50-100 plants were studied according to the color of the fruit and other economically useful characteristics.

Results.For eleven years, incuchination and selection were carried out on two-color forms of zucchini Russian spaghetti to achieve homozygosity and, accordingly, to align the material with the color of the fruit. Some regularities of the influence of the number of integrirovanii on the color of the fruit has not been observed. Continuing to observe the plants, it was possible to establish a relationship between the color of the fruit in technical ripeness and the pattern on the lower (first) leaves. On plants with a marble pattern, the leaves were mostly green (reticulated); with yellow spots on the leaves – two-colored and with completely yellow leaves – yellow fruits. By selecting plants with yellow spots on the leaves in the early stages, in the phase of the 3-4-th real leaves, we were able to increase the percentage of plants with two-colored fruits in the population of the variety to 95.5-100%. All this greatly simplified the original seed production of zucchini Russian spaghetti.
