Authors:   Lomonosov Moscow State University, Tikhonova Olga V. , Slobodyanyuk Anastasia A. ,   Lomonosov Moscow State University
Published: April 2021

The article presents the results of a study of the specifics of Russian media speech in the Republic of Moldova on the example of news broadcasts of the RTR Moldova TV-channel. The actual modern position of the Russian language on the territory of the country within the framework of the current state policy and the situation of Russian-language broadcasting in the country were studied. Theoretical material on the specifics of Russian language in the Republic of Moldova was studied and systematized. The history of the creation and specifics of the functioning of the Russian-language TV-channel RTR Moldova were reviewed in terms of current legislation. Methods of quantitative and comparative analysis, induction, synthesis of theoretical and practical knowledge were used. The study’s empirical base includes video material of 41 news programs of “Vesti-Moldova” and “Vesti nedeli-Moldova”. Broadcasts in 2019 comprised the overall chronological period of the research, thanks to the use of a “seasonal” sample (a week of winter, spring, summer and autumn seasons), which contributed to a more objective identification of the dynamics of the presenters’ and correspondents’ media speech on RTR Moldova. The article provides a classification of errors related to grammar, spelling, stylistics of offscreen text and logic of operational information presentation. The features of using means of artistic expression were also studied. Tendencies of bilingualism in the speech of inhabitants of the Republic of Moldova are indicated, which are reflected in the television broadcast, are highlighted in the article. At the same time, it is emphasized that on-air programs in Russian are in demand by the audience, however, at the state level, the process of imposing content in Romanian on the viewer is strongly supported. In this regard, the volume of Russian-language broadcasts is decreasing every year.
Is Saint Victorinus of Poetovio the author of the homily “On the ten virgins”?
Authors:   Ss. Cyril and Methodius Theological Institute of Postgraduate and Doctoral Studies, Khandoga Nikolay A.
Published: April 2021

The homily “On the ten virgins” for over 100 years has been a controversial work, since no strong argument has been presented by any scholar in favor of who is its author. The first group of researchers (for example, A.Wilmart, M.Špelič and M.Veronese) believes that its author is St. Victorinus of Poetovio, the first latin interpreter of Holy Scripture. The second group of researchers (for example, M.Dulaey, R.Gryson and N.A.Khandoga) ascribes it to Pseudo-Victorinus of Poetovio, an unknown Latin exegete of the Gospel of Matthew. Proceeding from this, the article makes an attempt at a theological and philological analysis of several quotes from the homily “On the ten virgins” and the original works of St. Victorinus of Poetovio — the treatise “On the creation of the world” and the interpretation of “On Revelation” and the fragment “On the life of Christ” — in order to identify the author of the homily. An important point in answering the question posed in the title of the article is Christology and eschatology as there is not one original writing by Victorinus of Poetovio, in which they would not be given appropriate attention. However, in the homily “On the ten virgins” these theological themes are not adequately addressed.
Contemporary problems of missionary work among the Samoyedic peoples
Authors:   St. Petersburg Theological Academy, Tserpitskaya Olga L. , Iakovov priest Daniil ,   Belgorod Orthodox Theological Seminary (with missionary focus)
Published: April 2021

The article examines one of the most important traditions of the Samoyedic peoples, which complicates the mission of the Russian Orthodox Church — the consumption of fresh blood of a young deer. This tradition refers to the practice of sacrifice, so it cannot be fully accepted by the Church as there is a canonical prohibition against consuming blood. As a result, a problem arises that hinders a successful mission among the Samoyedic peoples and impedes the growth of the Church. Despite the ban, there is also a modern medical assessment on the use of animal blood by humans, according to which a certain benefit of blood as a nutritional element is recognized. The state, in turn, is interested in maintaining the traditional way of life of the Nenets. It can be stated that the ban penetrated into new Testament Christianity under the influence of Judeo-Christians. The purpose of this article is to examine the effectiveness of missionary activity among the Samoyed peoples and to identify the possibility of missionary reception in light of the cultural tradition. The authors propose a new strategy for missionary work among the Samoyed people, which will be feasible if the Council of Bishops will consider relaxing the canonical prohibitions for the Samoyeds.
The Astrogenic Balance in the Aging Brain
Authors: Andromidas Fotis , Atashpanjeh Saeid , Myers Abigail J. , MacKinnon Brooke E. , Shaffer Melanie M. , Koob Andrew O.
Published: April 2021

An inverse correlation between the incidence of cancer and neurodegenerative disease
has been observed, with the prevalence of cancer peaking around 60 years of age, then slowly tapering
off as neurodegenerative diseases increase in the elderly. Although the diseases rarely occur
concurrently, the same genes are differentially expressed between the diseases, with four transcription
factors found to be in common for their expression. In the brain, mature astrocytes are the
origin of astrocytoma, which make up 58.2% of malignant brain tumors in patients 65 or older,
while GFAP+ astrocyte-like neural stem cells from the subventricular zone give rise to glioblastoma
and anaplastic astrocytoma, which make up 41.6%. Likewise, in neurodegenerative disease, a decrease
in astrocyte density is observed in early disease states, and senescent astrocytes increase.
Because astrocytes coordinate synaptic function, astrocyte dysfunction likely contributes to or causes
initial synapse loss and cognitive decline seen in neurodegenerative disease. In non-disease
states, astrocytes retain their ability to successfully re-enter the cell cycle through adult astrogenesis
to maintain the neuroenvironment, and controlled astrocytic proliferation could be an important
contributor to neurological function. Disruption to this astrogenic balance could account for the
inverse correlation of cell cycle dysregulation resulting in malignant astrocytes and tumorigenesis,
and astrocytic senescence and cell death without self-renewal in aging resulting in neurodegenerative
disease. The current understanding of the astrocytic roles of the transcription factors that could
be the cause of this imbalance will be discussed, as well as possible therapeutic approaches to modulate
their expression in the astrocyte.

Published: April 2021

Superfood is the name coined by the marketing industries to segregate the food
which is claimed to have an edge over the common food, having increased nutritional efficiency,
and possessing more amounts of antioxidants which lead to the prevention of many coronary
heart diseases. The history and introduction of the superfood have been discussed through
brief instances, and nutritional analysis of some of the most popularly available superfoods like
quinoa, goji berry, acai berry, etc. has been done. Some of the indigenous superfood nutritional
benefits have also been stated. The need and value with respect to the therapeutic and economic
aspects of the superfood are reported in the present review in accordance with the current

Published: April 2021

:

The Santa Barbara Amorphous (SBA-15), with a large surface area covered with abundant
Si-OH active groups on the walls of its pores, can be modified with various organic compounds
to build organic-inorganic hybrid materials, which can be used as a catalyst in organic reactions,
drug delivery systems, nano sorbent due to its high capacity for removing heavy metals in
waste water and as chemosensors for ions. Tunable and straight channels of SBA-15 facilitate the
entrance and diffusion of ions through the channels. This paper presents a review of the past five
years of literature covering the application of SBA-15 as an ions chemosensor in the liquid and
gaseous media.
Utilizing Health Behavior Change and Technology Acceptance Models to Predict the Adoption of COVID-19 Contact Tracing Apps: Cross-sectional Survey Study
Authors: Tomczyk Samuel , Barth Simon , Schmidt Silke , Muehlan Holger
Published: April 2021

Background

To combat the global COVID-19 pandemic, contact tracing apps have been discussed as digital health solutions to track infection chains and provide appropriate information. However, observational studies point to low acceptance in most countries, and few studies have yet examined theory-based predictors of app use in the general population to guide health communication efforts.

Objective

This study utilizes established health behavior change and technology acceptance models to predict adoption intentions and frequency of current app use.

Methods

We conducted a cross-sectional online survey between May and July 2020 in a German convenience sample (N=349; mean age 35.62 years; n=226, 65.3% female). To inspect the incremental validity of model constructs as well as additional variables (privacy concerns, personalization), hierarchical regression models were applied, controlling for covariates.

Results

The theory of planned behavior and the unified theory of acceptance and use of technology predicted adoption intentions (R2=56%-63%) and frequency of current app use (R2=33%-37%). A combined model only marginally increased the predictive value by about 5%, but lower privacy concerns and higher threat appraisals (ie, anticipatory anxiety) significantly predicted app use when included as additional variables. Moreover, the impact of perceived usefulness was positive for adoption intentions but negative for frequency of current app use.

Conclusions

This study identified several theory-based predictors of contact tracing app use. However, few constructs, such as social norms, have a consistent positive effect across models and outcomes. Further research is required to replicate these observations, and to examine the interconnectedness of these constructs and their impact throughout the pandemic. Nevertheless, the findings suggest that promulgating affirmative social norms and positive emotional effects of app use, as well as addressing health concerns, might be promising strategies to foster adoption intentions and app use in the general population.
Health Behavior Survey Among People Who Use Opioids: Protocol for Implementing Technology-Based Rapid Response Surveillance in Community Settings
Authors: Frew Paula M , Randall Laura A , King Adrian R , Schamel Jay T , Spaulding Anne C ,   HBOU Study Team, Holloway Ian W
Published: April 2021

Background

In 2018, 2 million Americans met the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition diagnostic criteria for an opioid use disorder, and 9.9 million Americans had misused prescription pain relievers the previous year. Despite a rapid increase in opioid misuse, opioid use disorders, and overdoses, data are limited on the behavioral and contextual risks as well as the protective factors fueling the opioid epidemic in some hard hit US cities—Atlanta, Los Angeles, and Las Vegas. Opioid use also contributes to the risk of other health problems such as HIV and hepatitis C virus infections or mental health disorders and is linked to behavioral and environmental risks (eg, homelessness, experiences of violence, involvement in the justice system). Knowledge of the relationships between these linked vulnerabilities and how they influence service utilization is critical to effective policy and interventions.

Objective

This survey explores the relationships between demographic and economic characteristics, behavioral and environmental risk factors, and service utilization of people who use opioids to inform public health practice, policy, and future efforts to mitigate the risks faced by this population experiencing multiple health, social, and economic vulnerabilities. The results of this survey will be used to identify needs and intervention points for people who use drugs currently served by public health organizations.

Methods

We implemented a community-engaged strategy that involved development and execution of a two-stage purposive sampling plan involving selection of partner organizations (syringe exchange programs in urban settings) and recruitment and enrollment of participants aged 18-69 years served by these organizations in Atlanta, Los Angeles, and Las Vegas from 2019 to 2020. The recruited participants completed a survey, including a variety of measures to assess health (physical and mental) and health behaviors such as sexual behavior, vaccine receipt, and HIV/ hepatitis C virus infection testing. Additional items assessed drug use and misuse, syringe exchange and health service utilization, sex exchange, histories of interpersonal violence, and vaccine confidence.

Results

This protocol was successfully implemented despite challenges such as real-time technology issues and rapidly finding and surveying a difficult-to-reach population. We sampled 1127 unique participants (248 in Atlanta, 465 in Los Angeles, and 414 in Las Vegas).

Conclusions

The establishment and utilization of strong community partnerships enabled the rapid collection of data from a typically difficult-to-reach population. Local efforts such as these are needed to develop policies and practices that promote harm reduction among people who use opioids.

Impact of Public Health and Social Measures on the COVID-19 Pandemic in the United States and Other Countries: Descriptive Analysis
Authors: Zweig Sophia Alison , Zapf Alexander John , Xu Hanmeng , Li Qingfeng , Agarwal Smisha , Labrique Alain Bernard , Peters David H
Published: April 2021

Background

The United States of America has the highest global number of COVID-19 cases and deaths, which may be due in part to delays and inconsistencies in implementing public health and social measures (PHSMs).

Objective

In this descriptive analysis, we analyzed the epidemiological evidence for the impact of PHSMs on COVID-19 transmission in the United States and compared these data to those for 10 other countries of varying income levels, population sizes, and geographies.

Methods

We compared PHSM implementation timing and stringency against COVID-19 daily case counts in the United States and against those in Canada, China, Ethiopia, Japan, Kazakhstan, New Zealand, Singapore, South Korea, Vietnam, and Zimbabwe from January 1 to November 25, 2020. We descriptively analyzed the impact of border closures, contact tracing, household confinement, mandated face masks, quarantine and isolation, school closures, limited gatherings, and states of emergency on COVID-19 case counts. We also compared the relationship between global socioeconomic indicators and national pandemic trajectories across the 11 countries. PHSMs and case count data were derived from various surveillance systems, including the Health Intervention Tracking for COVID-19 database, the World Health Organization PHSM database, and the European Centre for Disease Prevention and Control.

Results

Implementing a specific package of 4 PHSMs (quarantine and isolation, school closures, household confinement, and the limiting of social gatherings) early and stringently was observed to coincide with lower case counts and transmission durations in Vietnam, Zimbabwe, New Zealand, South Korea, Ethiopia, and Kazakhstan. In contrast, the United States implemented few PHSMs stringently or early and did not use this successful package. Across the 11 countries, national income positively correlated (r=0.624) with cumulative COVID-19 incidence.

Conclusions

Our findings suggest that early implementation, consistent execution, adequate duration, and high adherence to PHSMs represent key factors of reducing the spread of COVID-19. Although national income may be related to COVID-19 progression, a country’s wealth appears to be less important in controlling the pandemic and more important in taking rapid, centralized, and consistent public health action.

Authors: Wang Menghua , Liao Banghua , Jian Zhongyu , Jin Xi , Xiang Liyuan , Yuan Chi , Li Hong , Wang Kunjie
Published: April 2021

BACKGROUND

Due to the influence of the COVID-19 pandemic, conventional face-to-face academic conferences have been restricted, and many of these conferences have moved onto the internet.

OBJECTIVE

The aim of this study was to investigate the virtual conferences in the field of urology during the COVID-19 pandemic and provide suggestions for better organization of such conferences.

METHODS

A cross-sectional survey was conducted from May 30 to June 15, 2020, in China. Our team designed a 23-item questionnaire to investigate the conferences attended by urologists during the COVID-19 pandemic. SPSS 22.0 (IBM Corporation) was applied to analyze the data collected.

RESULTS

A total of 330 Chinese urologists participated in our survey, and the response rate was 89.7% (330/368). Among the participants, 40.9% (135/330) were associate chief physicians. The proportion of participants who took part in conventional face-to-face academic conferences decreased from 92.7% (306/330) before the COVID-19 pandemic to 22.1% (73/330) during the pandemic (P<.001). In contrast, the proportion of urologists who took part in virtual conferences increased from 69.4% (229/330) to 90% (297/330) (P<.001). Most urologists (70.7%, 210/297) chose to participate in the virtual conferences at home and thought that a meeting length of 1-2 hours was most appropriate. Among the urologists, 73.7% (219/297) reported that their participation in the virtual conferences went smoothly, while the remaining respondents reported that they had experienced lags in video and audio streaming during the virtual conferences. When comparing conventional face-to-face conferences with virtual conferences, 70.7% (210/297) of the respondents thought that both conference formats were acceptable, while 17.9% (53/297) preferred virtual conferences and 11.5% (34/297) preferred conventional face-to-face meetings.

CONCLUSIONS

Virtual conferences are increasing in popularity during the COVID-19 pandemic; however, many aspects of these conferences could be improved for better organization.
Feminist Bestsellers: A Digital History of 1970s Feminism
Authors: Moravec Michelle , Chang Kent K.
Published: April 2021

Feminism of the 1970s remains among the most influential social movements within the United States. Bestselling texts played a crucial role in spreading feminism beyond early activists into the mainstream of American society. Contemporary scholars of feminism continue to rely on these works as pivotal historical sources. This paper utilizes quantitative methods to compare six feminist bestsellers from 1970. Our data consists of three subcorpora of digitized books published in 1970 found in the Hathi Trust: six feminist bestsellers, a sample of non-fiction, and a sample of writing about women. Computational textual analysis identifies each bestselling title’s salient features and the contributions each text made at this key moment in the development of feminist thought. These results led us to propose a historiographical intervention that credits one bestseller, The Black Woman, with a more prominent role in the development of 1970s feminism.

Published: April 2021

Aim:
To systematically review ibuprofen, including versus indomethacin and paracetamol/acetaminophen, for the closure of patent ductus arteriosus (PDA).
Methods:
Pubmed, Embase, Cochrane and gray literature were searched to summarize ibuprofen outcomes in closure of PDA in published meta-analyses (MAs).
Results:
Seven MAs were included. Including high dose (HD) use, ibuprofen is equivalent/superior to indomethacin, and inferior/equivalent to paracetamol. Oral ibuprofen had higher efficacy than IV ibuprofen, including compared with indomethacin and paracetamol. Ibuprofen had safety advantages over indomethacin. Indomethacin and paracetamol had safety advantages over IV ibuprofen. HD of ibuprofen increases efficacy, but not toxicity.
Conclusion:
Evidence on ibuprofen effectiveness and safety, including the dosage forms, is limited by heterogeneity in doses and the levels of methods quality and risk of bias.

Gut microbial-derived short-chain fatty acids and bone: a potential role in fracture healing
Authors: Wallimann A , Magrath W , Thompson K , Moriarty T , Richards RG , Akdis CA , O'Mahony L , Hernandez
Published: April 2021

Bone healing complications such as delayed healing or non-union affect 5-10 % of patients with a long-bone fracture and lead to reduced quality of life and increased health-care costs. The gut microbiota and the metabolites they produce, mainly short-chain fatty acids (SCFAs), have been shown to impact nearly all organs of the human body including bone. SCFAs show broad activity in positively influencing bone healing outcomes either by acting directly on cell types involved in fracture healing, such as osteoblasts, osteoclasts, chondrocytes and fibroblasts, or indirectly, by shaping an appropriate anti-inflammatory and immune regulatory response. Due to the ability of SCFAs to influence osteoblast and osteoclast differentiation, SCFAs may also affect the integration of orthopaedic implants in bone. In addition, SCFA-derivatives have already been used in a variety of tissue engineering constructs to reduce inflammation and induce bone tissue production. The present review summarises the current knowledge on the role of the gut microbiota, in particular through the action of SCFAs, in the individual stages of bone healing and provides insights into how SCFAs may be utilised in a manner beneficial for fracture healing and surgical reconstruction.
Crisis reproductiva, cuidados y sostenimiento en contextos de desastre. Experiencias comunitarias tras el terremoto en Ecuador
Authors: Vega Cristina , Torres Santana Ailynn , Paredes Myriam
Published: April 2021

El artículo aborda la comunalización del cuidado y el sostenimiento de la vida en condiciones de crisis. Partiendo de investigación cualitativa acerca de los procesos de reproducción en una localidad periférica de la costa manabita tras el terremoto de 2016 en Ecuador, el texto discute la potencia y los límites de la acción comunitaria. Ésta se rearticula cuando lo que resguarda el diario vivir -cobijo, alimentación, salud, educación, agua, etc.- colapsa. Inmersa en un contexto histórico de explotación laboral y territorial y de una limitada acción estatal, la población pone en marcha dinámicas de cooperación y cogestión en distintos frentes, y transforma las que operaban previamente. Discutiendo con la literatura sobre cuidado, comunidad y común desde el feminismo y la que trabaja sobre vulnerabilidad, riesgo y desastres, la pregunta central que motiva la reflexión es: ¿qué informa el análisis de este tipo de crisis sobre las prácticas comunales de reproducción social?

Entre recalibración y continuidad: el contexto del nacimiento del IMV
Authors: Arriba González de Durana Ana , Aguilar Hendrickson Manuel
Published: April 2021

España, a diferencia de otros países meridionales, recalibró desde los años 1980 su sistema de garantía de ingresos, conteniendo el nivel contributivo y creando un conjunto de programas asistenciales. A pesar de su significativo impacto, los límites e incoherencias de ese conjunto asistencial explican que, desde 2015, su reforma esté en la agenda política nacional. Aunque el conjunto existente tiene mayor impacto que sus equivalentes italiano o griego, su diseño está aún anclado en una concepción «fordista» que asocia empleo con seguridad económica. Este modelo se muestra insuficiente para hacer frente a las transformaciones de la estructura de los hogares, a las dificultades de acceso a la vivienda, pero sobre todo al crecimiento de formas precarias de participación en el empleo. El artículo analiza la trayectoria del conjunto de la garantía de ingresos en el que el nuevo Ingreso Mínimo Vital mejora apreciablemente la cobertura asistencial, pero deja sin resolver la adecuación del conjunto a las nuevas formas de empleo.
El ingreso mínimo vital: una perspectiva de género
Authors: Salido Cortés Olga
Published: April 2021

El debate sobre la renta básica y sus distintas formas, como el ingreso mínimo vital, ha descuidado con frecuencia su dimensión de género. La justificación de la nueva prestación, recién aprobada por el Gobierno de España, apela a las ideas de justicia y eficiencia en la distribución de los recursos, pero ¿hay lugar para la preocupación por la igualdad de género? En este artículo discutimos las distintas aproximaciones desde las que esta cuestión se ha abordado, evaluando los argumentos e identificando las preguntas clave que deberían marcar el debate actual en nuestro país para evitar impactos no queridos sobre el bienestar de las mujeres y la igualdad de género. ¿Hasta qué punto un ingreso mínimo vital puede considerarse un instrumento para la profundización de la igualdad de género? ¿Hay efectos potencialmente perversos que puedan ser anticipados?

Published: April 2021

This paper empirically investigates the potential benefits of outsourcing humanitarian logistics activities to commercial logistics service providers (LSPs) to improve rescue missions in the Al Zaatari Syrian refugee camp in Jordan. The study uses a quantitative research approach, a survey data set of 140 questionnaires was collected from the managers and managerial staff dealing with logistical activities. First, a comprehensive review of related literature was performed to guide this research and then to test the main hypotheses of this study, correlation and regression analysis were carried out. The findings confirmed that humanitarian organizations in Al Zaatary camp can get benefits from collaborating with LSPs on delivering primary logistic services (shelter, food, medicine, transportation, etc.) (Nurmala, de Leeuw, & Dullaert, 2017). Moreover, the findings showed that outsourcing is preferred in the response phase (Vega & Roussat, 2015). This paper contributes to the growing body of knowledge on humanitarian logistics in ways that fills a gap by empirically investigate the phenomenon, as well as it is considered well timed in the context of the still current situation due to political instability in the region. As far as the authors are aware, this research represents the first study within the humanitarian logistics sector in Jordan.

Food Security in Qatar during COVID-19 Pandemic
Authors: Ben-Hamadou Radhouane
Published: April 2021

The novel COVID-19 pandemic that affects global food production and accessibility is a great concern/risk towards different country’s capacity to the attainment of stable and sustaining food security. Thus, Qatar’s food security like every other country of the globe is under a threat because of the COVID-19 pandemic which has been so far well managed because of its robust policies, social structure and proactive measures. Before the pandemic, Qatar has strengthened its food security status through laudable fiscal policies that focus on the local production increment, diversifying the sources of food imports and edible items, and overseas agro-business to ensure stable food supply at affordable prices. Hence, this mini-review looks into the current state of food security in Qatar amidst the global COVID-19 pandemic to establish if the current trend will help ensure food availability and accessibility in the foreseeable future.

Published: April 2021

Plantas de tomate silvestre (Solanum pimpinellifolium L.) y comercial (S. lycopersicum L.) fueron mantenidas con solución hidropónica y con ensilado biológico de pescado, evaluando el crecimiento del tallo principal, número de ramas y porcentaje de materia seca. Las plantas de tomate silvestre que fueron regadas con el ensilado de pescado tuvieron un mayor crecimiento del tallo principal así como del número de ramas, mientras que ambas especies generaron un mayor porcentaje de materia seca en hojas. Estos resultados permiten sugerir que el nitrógeno del ensilado de pescado sería el componente importante para el mayor crecimiento de la parte aérea de estas plantas.

Bu çalışmada İzmir ve Bolu yöresinden elde edilen izolatların vejetatif uyum tipleri ilgili standart yöntemler kullanılarak belirlenmiştir. İzmir yöresinden 2015 yılında 34, 2016 yılında 7 farklı köyde seçilen aktif kanserlerden örnekler toplanmış ve elde edilen 409 izolatın 255 tanesi Avrupa uyum tiplerinden EU-12, 154 tanesi EU-1 uyum tipi olarak tespit edilmiştir. Vejetatif uyum tiplerinin bölgedeki dağılımı ortaya konmuş ve bölgeden elde edilen izolatlar içerisinde hipovirülent izolata rastlanmamıştır. Bolu yöresinde Akçakoca, Düzce, Yığılca ve Gölyaka Orman İşletme Müdürlüklerine bağlı kestane sahalarından iyileşen kanserden elde edilen 76 adet izolattan 2 adedi Avrupa uyum tiplerinden EU-12, 72 adedi ise EU-1 olarak belirlenirken 2 adedinin uyum tipi saptanamamıştır. 76 İzolatın 38 adeti hipovirülent, 38 adetinin de virülent olduğu tespit edilmiştir. Ayrıca yörede hipovirülensliğin yaygın olması ve ağaçlarda kanserden dolayı iyileşmeler olmasına rağmen kestane ormanlarında kurumalar da gözlenmiştir. Bolu yöresinde hipovirülent Cryphonectria parasitica fenotiplerinin varlığı ve yayılmaların doğal koşullarda meydana gelmesi, kestane kanseri etmeninin biyolojik kontrolü için umut vericidir. Bununla birlikte İzmir yöresi için bölgede yaygın olduğu uyum tiplerinin tespiti biyolojik mücadele çalışmalarının stratejisi için önemlidir.

Choroid plexus carcinomas (CPCs) are rare pediatric tumors with a generally poor prognosis. Currently there is no definite optimal treatment strategy for this neoplasm. This study is supported by the Independent Ethics Committee and approved by the Academic Council of the Dmitry Rogachev National Medical Research Center of Pediatric Hematology, Oncology and Immunology. This study included patients with a verified diagnosis of CPC at the age 0 to 18 years in the period from 01.01.2009 to 31.12.2019. A total of 32 patients were registered. The median age was 2.65 years; 93.5% of CPCs were localized in the lateral ventricles. Initial metastases were found in 21.8% of cases; 5-year event-free survival (EFS) in children with metastases was lower than in those who did not have metastases 29 ± 17% and 49 ± 12%. In our cohort, gross total resection (GTR) was performed in 65.6% of patients. The five-year EFS in patients with complete CPC removal was higher than in patients who underwent subtotal and partial resection (63 ± 13%, 12 ± 11%, and 0%, respectively). In addition, overall survival (OS) was slightly higher in those who underwent GTR compared with subtotal and partial resection (74 ± 12%, 67 ± 16%, and 0%, respectively). Of the 32 children with CPCs, 15 children received programm chemotherapy, 17 non-programm chemotherapy, 5-year EFS in patients who received programm and non-programm chemotherapy was 79 ± 11% and 0%, respectively (p = 0.0006), 5-year OS in patients who received programm and non-programm chemotherapy was 93 ± 7% and 36 ± 14% (p = 0.0054).
Place Matters for Health

Health is often conceptualized as an individual endeavour. When we are ill, the sickness—as far as the biomedical community is concerned—is experienced on asomatic bodily level. However, this particular perspective on health is severely myopic as it ignores the social nature of health. As recent research by geographers, urban planners, sociologists, and epidemiologists has indicated, our health outcomes arenot solely a product of our health ‘consciousness’ or biological/genetic variables, but are also a byproduct of where we reside and its immediate hinterlands—which include our neighbourhoods and the larger city. This presentation then looks to provide a brief synopsis of the research which speaks to how the morphology of our urban environment can influence our health outcomes. In particular, the presentation will focus on—what urban planners have coined—the ‘walkability’ of neighbourhoods and cities. It is found that residents living in areas that are rated as highly walkable often have lower prevalences of obesity and people that are overweight.
Partycypacja obywatelska jako utopijna wizja samorządzenia społeczności lokalnych… – na przykładzie miasta Krakowa

Civic participation is a term used to describe the participation of the citizens in makingand realizing decisions by the public government and administration. Civic participationcan take many forms, which in theory include different degrees of citizens’ engagementin decision making: informing, consulting, co-deciding. The catalogue of participationtechniques includes, based on the example of Krakow, many ways of civic participation, e.g.:local referendum, civic budget and participatory planning and designing. The examples ofparticipatory activities in the city of Krakow listed in this article exemplify serious problemswith the effective realization of this form of governing. It is especially important in the contextof the emerging postulates of replacing the traditional model of finances management ofa territorial self government unit with a mechanism based on the civic participation anddirect democracy. The idea in which the municipality budget is constructed by the way ofdemocratic discussion, in which every citizen can decide on what part of the public money isspent, belongs to the sphere of the impossible to realize utopia.Key words: civic participation, civic budget, Krakow self-government

En el presente estudio se evaluó el efecto de tres dosis de la giberelina Ryzup sumergidos en dos tiempos diferentes para inducir la brotación en papa (Solanum tuberosum) variedad canchán-INIA. Se utilizó un diseño completamente aleatorizado con seis tratamientos más un testigo absoluto. Las dosis de aplicación fueron 2,5, 5 y 7,5ml por 20l de agua. Los tiempos de inmersión presentaron dos niveles, de 5 y 15 minutos, respectivamente. Posteriormente utilizando el software libre R se efectuó el análisis de varianza y la prueba de comparaciones múltiples según Duncan por tratamientos. Las variables evaluadas fueron: porcentaje de la brotación, número de brotes por tubérculo, longitud de brotes por tubérculo y diámetro de brotes por tubérculo. Los resultados a los 33 días de haber instalado el ensayo mostraron que el T7 (7,5ml de Ryzup sumergidos durante 15 minutos) obtuvo los valores más altos y uniformes, exhibiendo un porcentaje de brotación del 85,26%, 8,36 brotes por tubérculo, 7,61 cm de longitud, y un diámetro de 5,41 cm por tubérculos. Se concluye que la aplicación de giberelinas acelera el proceso de brotación e induce el rompimiento del estado de reposo de las semillas, lo cual queda demostrado en el T7 que logró obtener los mejores valores a los 33 días, lo que resulta útil y accesible al agricultor ya que se traduce en una ganancia de tiempo de hasta dos meses, y posibilita la realización de hasta tres ciclos del cultivo al año.

La presente investigación se llevó a cabo en el área del vivero de la UNTRM, distrito de Chachapoyas, cuyo objetivo fue evaluar los métodos de escarificación física y mecánica en la emergencia y crecimiento de semillas de Caesalpinia espinosa. Se utilizó un diseño completo al azar (DCA), con tres repeticiones y ocho tratamientos.  Para el análisis de datos se utilizó el software R x 64 3.3.1 y la prueba de Duncan al 5%. Los tratamientos fueron: remojada en agua fría por 3 días (T1), remojada en agua fría por 5 días (T2), remojada en agua fría por 7 días (T3), picada y remojada por 12 horas (T4), picada y remojada por 24 horas (T5), remojada en agua caliente por 1 minuto y en agua fría por 12 horas (T6), remojada en agua caliente por 3 minutos y en agua fría por 12 horas (T7) y remojada en agua caliente por 5 minutos y en agua fría por 12 horas (T8). Las semillas se sembraron en sustrato a base de arena de río. Se aplicó riegos de 2-3 veces por semana. Las variables evaluadas fueron porcentaje de emergencia, altura de plántula, número de hojas, longitud de raíz e índice de velocidad de emergencia. Según los resultados obtenidos existieron diferencias significativas entre tratamientos donde el T4 y T5 lograron mayores porcentajes de emergencia con 91.67 y 93.75 %, altura de plántula con 7.85 y 8.97 cm y número de hojas con 3.70 y 3.87. Igualmente para el índice de velocidad de emergencia los valores más altos se obtuvieron en el T4 y T5 con 14.16 y 14.85 respectivamente, demostrándose así el efecto notorio de la escarificación mecánica sobre la emergencia y características morfológicas de plántulas de tara.
