Resveratrol administration prevents radiation-related changes in metabolic profiles of hearts 20 weeks after irradiation of mice with a single 2 Gy dose
Authors: Gramatyka Michalina , Widłak Piotr , Gabryś Dorota , Kulik Roland , Sokół Maria
Published: December 2020

We aimed to evaluate whether resveratrol affects radiation-induced changes in metabolite profiles of the mouse heart. Hearts were irradiated in vivo with a single 2 Gy dose during the resveratrol administration and metabolite profiles of heart tissue were analyzed by the untargeted HR-MAS NMR approach twenty weeks after irradiation. The administration of resveratrol mitigated the radiation-induced decline in the content of choline-containing compounds and unsaturated lipids, which might reflect the stabilization of cell membrane structure against radiation-related damage. Results obtained with this mouse model suggest that the resveratrol supplementation may prevent metabolic changes related to radiation-induced damage in the heart.
In-vitro activity of lipoic acid against Ureaplasma urealyticum and Ureaplasma parvum isolated from women with infections of the urogenital tract. A pilot study
Authors: Biernat-Sudolska Małgorzata , Rojek-Zakrzewska Danuta , Bilska-Wilkosz Anna
Published: December 2020

Several species of Ureaplasma bacteria are known to be present in the urogenital tract of humans, in both healthy individuals and symptomatic patients. These pathogens are associated with urogenital tract infections, infertility problems and spontaneous abortion in humans. The present study involved 77 strains of Ureaplasma species (Ureaplasma spp.), including 21 Ureaplasma urealyticum (U. urealyticum) strains and 56 Ureaplasma parvum (U. parvum) strains. Lipoic acid (LA) and its reduced form dihydrolipoic acid (DHLA) are synthesized in all prokaryotic and eukaryotic cells. Research of recent years increasingly points to therapeutic properties of exogenously supplemented LA. In our study, we examined for the first time the effect of LA on the bacteria multiplication and its bactericidal activity against U. urealyticum and U. parvum. The LA concentrations used were: 1200 µg/ml, 120 µg/ml, and 12 µg/ml. The titer for each strain of Ureaplasma spp. was estimated using the color changing units (CCU) assay. For CCU measurements, a series of 10-fold dilutions of each cell culture in 0.9% NaCl (titration) was prepared and 1 CCU/ml was defined as the highest dilution of cells at which color change was detected. The strongest bacteriostatic and bactericidal effect of LA was observed at a concentration of 1200 µg/ml. In contrast, at lower LA concentrations, stimulation of the bacteria multiplication was noted for 14% of the total number of strains tested. Taken together, the current data provide novel findings about potential beneficial antimicrobial effects of LA.
The Experience of the Empirical Research on Social Intolerance
Authors:   Saratov State University, Kruglov Aleksandr V. , Nikiforov Yaroslav A. ,   Saratov State University
Published: December 2020

The article is devoted to the problem of the empirical study of the phenomenon of social intolerance. The analysis of the results of sociological studies conducted in the USA and Western Europe in the second half of the XX – early XXI centuries is given. The relevant dimensions of tolerance are the subject of the ongoing debate. Scientists do not agree on the question of whether measuring tolerance in different ways is important for identifying the origin of tolerance. Comparing the two methods of measuring tolerance leads to the conclusion that both methods accurately measure intolerance and do not differ significantly in their conclusions regarding the foundations of intolerance. Both methods of measuring tolerance which have now become classical, however, fail in identifying intolerance for certain actions, but not for groups. The research also shows that people distinguish between different actions and between different groups they are willing to endure, also depending on their own social identity. Therefore, tolerance cannot be conceptualized as a comprehensive phenomenon and should be seen as a multi factorial and context-sensitive one. Despite the fact that intolerance and tolerance are often considered as opposite poles, Western researchers point to the asymmetry of tolerance and intolerance.

Authors:   Saratov State University, Elutina Marina E. , Sitnikova Svetlana V. ,   Saratov State University, Semenova Julia A. ,   Saratov State University
Published: December 2020

The article deals with age-specific features of women’s entrepreneurial activity on the example of the women entrepreneurs in Saratov region. The logic of the work is built around the identification of the age profile of women’s entrepreneurship, as well as the age specificity of the key components of women’s entrepreneurial activity. On the basis of the analysis of quantitative and qualitative research materials, a socio-demographic portrait of a woman entrepreneur and the profile of her activities were drawn up, as well as age-specific features of women’s entrepreneurial activity were described in detail. The representatives of the older age group of women entrepreneurs are characterized by the forced start of entrepreneurial activity, the possibility of prolongation of which is inextricably linked with the personal characteristics of the leader. The entrepreneurship of the middle and younger age groups is associated with the accumulation of human and social capital and entry into the market through the accessible niche. For them the protocols and hierarchies are less important but a reliable system of financial compensation and the possibility of personal growth present significant motivational factors.
The Mobility Turn as an Educational Challenge in Modern Society
Authors:   Saratov State University, Vlasov Timofey S. , Nemeryuk Evgeniya E. ,   Saratov State University
Published: December 2020

The article discusses the main idea of the study, that is discovering a number of problems generated by social dynamics and mobility. By using the methodological potential of sociology, the essence and logic of the mobility turn as a metaphor for the development of modern society is demonstrated. The radical changes in sociocultural dynamics that are also achieved by modern social sciences (sociology of mobility and other postmodern concepts) are shown. By using the methodological approaches of the sociology of education, the «order of the day» mobility problems in higher education are formulated. It is stressed that the educational sphere also becomes mobile, transforming the nature of human life, as well as updating some special phenomenon, such as academic mobility. The horizon of future research in connection with the complex nature of the problem under study is demonstrated by formulating the “order of the day” of mobility challenges for modern higher education.
“Ethnicity” and “Politicalness”: Inversion in Modern Mythology of Civil Political Subjectivity
Authors:   Saratov State University, Shestov Nikolay I.
Published: December 2020

The article is devoted to analysis of one of the reasons why today in the world, including Russia and “Western” states with long-standing liberal traditions, governing elites and civil societies’ critical attitude to institutions, values, and practices of liberal democratic policy is growing. The author explains the grow of such dissatisfaction by inversion of two stereotypical (social and mythological) civil identities and corresponding motivations for political participation. One of the stereotypical notions of democratic politics ideal and optimal mode of citizens’ participation in it is called “politicalness”, while the other – “ethnicity”. Inversion of senses of such mythologemas creates a crisis situation within the space of modern civil societies’ political culture. Followers of “politicalness” of liberal-democratic policy regard excessive orientation on specific “ethnic” values and traditional technologies of citizens’ participation as its key drawback. Those who support “ethnicity” of liberal-democratic policy, on the contrary, are discontented with its focus on vague (universal human) values and disconnection from cultural conditions within which democratic process exists in different parts of the world. In author’s view, the result is spreading of unstable civil identities and distrust in liberal democratic policy.

Published: December 2020

Based on the analysis of scholarly discourse on the results of Bologna Declaration goals and principles’ incorporation into reformation of higher education system in Russia and through their own experience of teaching in higher education institutions, the authors come to conclusion that commitment to accession into the world educational space was caused not so much by real domestic needs to improve home higher education system but by political factors as a result of slow-response impact of a liberal reformation strategy of the 1990s. Expediency to concentrate intellectual resources of university academia necessary for digitalization of educational process in compliance with the aims and needs of economy and the whole society is substantiated.

The Philosophy of “a New Christianity” by F. M. Dostoevsky
Authors:   Altai State Pedagogical University, Ekshibarova Olga V.
Published: December 2020

The article is devoted to the philosophical views and world outlook of F. M. Dostoevsky. The author analyzes the validity of accusation of Dostoevsky in “a new Christianity”. Based on the comparison of the writer’s own thoughts and polemical statements about his work by such philosophers as V. S. Solovyov, V. V. Rozanov, D. S. Merezhkovsky, and M. I. Tugan-Baranovsky, the author provides the description of Dostoevsky’s “new Christianity”. The hermeneutical method allows the author to analyze both the primary sources of Christian thought (the New and the Old Testaments), as well as the works by Dostoevsky and the articles of his contemporaries, who discuss the writer’s philosophical views. The purpose of this work is to compare the concept of “the new Christianity of Dostoevsky” with the understanding of “Christianity” as such. This comparison, not previously considered, is a new perspective on the writer’s philosophical worldview. The article compares the main aspects of Christianity (freedom of choice, spiritual revival, the gospel as a source of enlightenment) in the first Apostolic understanding and in the works by Dostoevsky. Based on the analysis of the comparison, it is concluded that Dostoevsky’s “new Christianity” supports the principles of the first Apostolic Christianity. However, at the same time, Dostoevsky’s “new Christianity” sees the way of development of modern Christianity in a spiritual and moral, “educational” aspect. Thus the problem of whether Dostoevsky’s “new Christianity” is the author’s interpretation of Christianity by the writer is considered and solved.
Academization of an Individual in Musical Education
Authors:   Saratov State Conservatory named after L. V. Sobinov, Varlamov Dmitry I.
Published: December 2020

Academization of art is based on the evolution of thinking and artistic creativity of mankind, which allows considering this process as a global one, both temporally and spatially. However, in musical educational establishments in the process of future musicians training, thinking and creativity of each student is academized separately, which allows us to talk about individual academization. In this aspect, academization is studied for the first time. The article defines characteristic features of individual academization: first, temporary duration – while the global academization lasts for centuries and millennia, the individual academization is limited by the years and decades of learning the art by the individual; secondly, as in the vast majority of cases private academization takes place in educational organizations, it is always artificial in type. At the same time, as the author’s previously published articles demonstrate, artificial academization is more often characterized by the greater number of negative trends (so-called post-academic syndrome) and is more acute (painful) than a natural academization process. This fact requires special attention of specialists to the content of music education and the choice of teaching methods.

The article analyzes the processes of initial placement of tokens (moent), as well as possible options for their legal regulation. The methodological basis for the research of this article is the dialectical method of scientific knowledge. The research used such general scientific methods and techniques as scientific abstraction, system, logical, analysis and synthesis, comparative law. Conclusions are drawn that 1) various approaches to the issue of ICO regulation have been formed in a number of countries, and rather ambiguous ones, 2) Russia is currently in the process of forming a legal framework regulating the circulation of cryptocurrencies and digital financial assets, 3) the term “ICO” has not been introduced in domestic legislation, and the terms “issue” and “circulation”are used instead. Scientific and practical significance. This research allows us to consider the nature of the token and the content of the ICO process, as well as contributes to the development of theoretical directions on this topic and the formation of training courses on tokens and new ways of implementing financial relations.
Reformulation of Allah’s Ownership on Waqf (Theoretical Analysis Toward Syāfi’i School)
Authors: Ghozalie Fathurrohman , Muallim Amir , Tono Sidik
Published: December 2020

Abstract: Waqf is the act of someone who holds some of his property and gives the benefits of the property. Waqf in Indonesia generally follows the opinion of the Shafi'i school that said the waqf property belongs to Allah. This opinion is not right in Islamic ownership perspective which said that every property must be owned by humans unless it is specified by the Shari'a. This research is normative Islamic law research with the theory of ownership in Islam and the maslaha theory. This research found that Allah's ownership of waqf property needs to be reformulated to equate it to the theory of ownership in Islam and to be useful for human life. This reformulation is by establishing the legal entity as the owner of the waqf property because the legal entity can represent God's ownership. Keywords: Reformulation; Ownership; Waqf; Benefit Abstrak: Wakaf adalah perbuatan seseorang yang menahan sebagian hartanya dan mensedekahkan manfaat harta tersebut. Perwakafan di Indonesia pada umumnya mengikuti pendapat mazhab Syafi’i yang mengatakan bahwa harta wakaf menjadi milik Allah. Paham tersebut tidak sesuai dengan ketentuan tentang kepemilikan dalam Islam yang menetapkan bahwa setiap benda yang ada di muka bumi harus dimiliki oleh manusia kecuali ditentukan lain oleh syariat. Penelitian ini adalah penelitian hukum Islam normatif dengan pendekatan teori kepemilikan dalam Islam dan teori kemaslahatan.  Penelitian ini menemukan bahwa kepemilikan Allah atas harta wakaf perlu direformulasi supaya sesuai dengan ketentuan tentang  kepemilikan dalam Islam dan supaya bermaslahat bagi kehidupan manusia. Reformulasi tersebut ialah dengan menetapkan badan hukum sebagai pemilik harta wakaf karena badan hukum dapat merepresentasikan kepemilikan Allah. Kata kunci: Reformulasi, Kepemilikan, Harta wakaf, Kemaslahatan
A família como instituição política e a teoria das capacidades de Martha Nussbaum
Authors: Tramontina Robison , Arcaro Larissa Thielle
Published: December 2020

Trata-se de analisar a desigualdade de gênero no exercício do cuidado à luz do enfoque das capacidades de Martha Nussbaum. A dicotomia público/privado serviu/serve como estrutura conceitual justificadora para restringir a participação das mulheres na esfera política, para inviabilizar a realização de seus projetos pessoais e profissionais e para acobertar o processo de “naturalização” do âmbito doméstico como espaço eminentemente feminino. A partir do questionamento dessa par dicotômico, o artigo objetiva demonstrar como a desigualdade de gênero no desempenho do cuidado implica expressivas desvantagens às mulheres e inviabiliza o desenvolvimentos das capacidade humanas centrais.

Authors: Nascimento Erasmo Henrique de Araújo , Henklain Marcelo Henrique Oliveira
Published: December 2020

Existem diversas pesquisas sobre Análise do Comportamento nas Organizações desenvolvidas no Brasil, mas esta subárea da Análise do Comportamento ainda carece de maior divulgação e ampliação da produção. Diante disso, o objetivo deste estudo foi realizar uma revisão de literatura sobre a produção analítico-comportamental brasileira nas organizações no período de 1970 a 2017. Foram consultadas as seguintes fontes de informação: (a) dissertações e teses: sites de programas de pós-graduação com orientadores e/ou linhas de pesquisa em Análise do Comportamento e a Biblioteca Digital Brasileira de Teses e Dissertações; (b) artigos: Portal de Periódicos da Capes; (c) ao final das consultas, o banco de dados foi complementado com trabalhos da Biblioteca em OBM. Os descritores utilizados e os procedimentos de seleção de trabalhos variaram a depender da base de dados adotada. Os resultados sugerem que a produção nacional tem crescido na última década, apesar dessa produção estar concentrada no sul e sudeste do país. Verificou-se também, a partir de uma análise das palavras mais frequentes, compatibilidade entre os trabalhos encontrados e conceitos que caracterizam a teoria e a atuação analítico-comportamental. Sugere-se que pesquisas futuras ampliem o presente exame incluindo capítulos de livro e trabalhos apresentados em eventos.
Joint lesions in inflammatory bowel diseases: the analysis of the Moscow regional patient registry and a clinical case
Authors: Taratina O. V. , Belousova E. A.
Published: December 2020

Rationale: Extraintestinal manifestations (EIM) of an inflammatory bowel disease (IBD) are a sign of its more severe course. Joint lesions are most common among IBD EIM.

Aim: To evaluate the prevalence and types of joint lesions in the population of IBD patients of the Moscow region.

Materials and methods: We performed a  retrospective analysis of medical files of the patients who were admitted to the Moscow Region Inflammatory Bowel Disease Center (MONIKI) for examination and treatment from August 1, 2019, to March 1, 2020. The study included 70 patients with confirmed diagnoses of IBD and confirmed or suspected involvement of the joints.

Results: Thirty six of 70 patients with IBD and EIM (51.43%) had been diagnosed with Crohn's disease (CD), and 34 (48.57%) with ulcerative colitis (UC). The CD group included more men (n=21, 58.33%), whereas their proportion in the UC group was 47.02% (n=16). The mean age at CD diagnosis in the UC and CD groups was comparable: 38.3±13.7  years in men with CD and 40.5±12.8 years in men with UC, 37.7±11.1 years in women with CD and 35.7±14.0 in women with UC. The most prevalent among all IBD patients were X-ray negative peripheral arthralgias. Among joint lesions confirmed by radiological diagnostics, sacroileitis was most prevalent both in all IBD patients (24.3%), as well as in the UC group (17.6%), whereas in the CD patients its frequency was the same as that of ankylosing spondyloarthritis (AS) (30.6% of the cases). AS ranked second in the prevalence of joint lesions in the UC group (8.8%) and all IBD (20%). Psoriatic arthritis was diagnosed only in the CD patients (2 / 36). We describe a clinical case of CD with AS, complicated with psoriatic rash, treated with a  monoclonal antibody to tumor necrosis factor alfa (anti-TNF-α).

Conclusion: Peripheral arthropathias were most prevalent among all joint lesions in the group studied. EIM mirror a more aggressive phenotype of the disease and higher glucocorticosteroids requirements. Administration of anti-TNF-α agents allows for the control of both intestinal IBD manifestations and of the joint syndrome. However, drug-associated skin adverse event can occur during treatment with this drug class. In such a case, it is possible to switch the biological therapy to another class of drugs that we have demonstrated with the given clinical example.

Effect of Melatonin and Lighting Regime on Physiological Responses and Haematological Profile of Isa Brown laying Birds
Authors: Igwe R.O. , Herbert U. , Oguike M.A. , Osakwe I.I.
Published: December 2020

Background: Melatonin is the main neurohormone synthesized and released by the pineal gland. It stimulates several antioxidative enzymes which increase its efficiency as an antioxidant and enhance the maturation of oocytes and the development of follicles in animals. Artificial lighting on the other hand improves bird’s performance especially reproductive performance and behavior. By providing artificial light, growers can manipulate this natural cycle to their advantage and increase the egg laying. Therefore, this current study was aimed to evaluate the effect of melatonin and increased lighting on the welfare of laying birds. Methods: In November 2018 to December 2019, a total 162 sixteen weeks Isa Brown hens were used for the experiment which was grouped into 9 treatments. Melatonin and lighting at three levels (0mg, 5mg, 10mg and 12hrs, 15hrs and 18hrs) were administered orally to the birds four times weekly within a day interval for 30 weeks from 16 weeks to 46 weeks. Data on rectal temperature, respiratory rate and heart rate were collected and analysed. Blood samples were also collected and analysed for haematological parameters. Result: Results showed that rectal temperature (RT), respiratory rate (RR) and heart rate (HT) were significantly (p less than 0.05) influenced by both melatonin and lighting. Melatonin at 5mg significantly (p less than 0.05) reduced the rectal temperature (40.55oC), respiratory rate (139.44bpm) and heart rate (320bpm) while lighting at 18 hours significantly (p less than 0.05) increased the rectal temperature, respiratory rate and heart rate due to heat stress among the parameters. The haematological profiles were influenced (p less than 0.05) by the administration of melatonin. Treatments levels on melatonin administration (5mg and 10mg) had increased circulating packed cell volume of 28.00% and 28.11% respectively compared to the control group which had 25.66%. The results indicates that melatonin at 5mg and 10mg improved the welfare of the birds but increased lighting beyond 12 hours compromised immunity of the birds.

Authors: Touloun Oulaid , Moudden Naima
Published: December 2020

Background: Scorpionism is considered as one of the health and medical problem in undeveloped tropical and subtropical countries in the world. In Morocco, Azilal province is considered among the most Moroccan regions affected by the scorpion sting and envenomation. Despite of its epidemiological status, little is known about the distribution of scorpions in Azilal province. Any strategy against these envenomation must first go through a good knowledge of the composition and distribution of scorpion fauna involved. The current study aimed to study the scorpion fauna of this province in order to manage and control scorpionism related problems. Methods: In this field-laboratory investigation during 2014-2017, different localities of Azilal province were surveyed. 14 sampling localities were selected based on geographical situation, climate and local data. In the laboratory, the collected scorpions were determined morphologically based on the valid taxonomic keys. Conclusion: Our investigations in the Azilal province have allowed to us to inventory seven species. Among the inventoried species some are deemed dangerous for humans. The geographical distribution of collected species was discussed. The present work will be a complementary contribution to the comprehensive study of the scorpion sting syndrome in Morocco.

Ovu, is a sub-clan in Delta State, Nigeria which comprised of: Ovu-Inland, Okoemaka, Ekpan, Urhodo, Okoroke and Oviorie that are mostly farmers without the knowledge of their soil fertility. The study investigated soil fertility status of Ovu Sub-Clan. Methods: Cassava, oil palm and plantain farms were randomly selected in the six community and 118 representative soil samples were taken. Soil pH, organic carbon, total nitrogen, available phosphorus content of soil and exchangeable bases were measured. Data were analyzed with descriptive statistics and Parker’s nutrient index was used to compare the fertility level. Result: The cassava, oil palm and plantain farms were slightly acidic mean values of 6.4±0.38, 6.5±0.31 and 6.4±0.30, respectively indicating slight acidity. Organic carbon was low to high while total nitrogen was high except at Okoemaka that was moderate (0.19±0.04%). Available phosphorus content was low to medium while exchangeable potassium and calcium were medium to high, exchangeable magnesium was low to medium. Nutrient index showed that soil pH was moderate and while total nitrogen was high.

História social da criança proletária
Authors: Hermida Jorge Fernando
Published: December 2020

Dentro das intencionalidades possíveis, este artigo se colocou como desafio contribuir para a composição de uma proposta de história social da criança proletária, tendo em vista as interpretações e perspectivas históricas idealistas, não históricas, hibridas, parciais e descontextualizadas que existem sobre as visões, os sentidos e os modos de conceber as crianças e o conceito de infância desde os primórdios da Revolução Industrial até os nossos dias. Ao analisar a produção acadêmica nacional e internacional, constatamos um denominador em comum: mesmo existindo uma grande variedade e quantidade de pesquisas vinculadas a diversos âmbitos da criança e sua infância, os estudos sobre crianças proletárias em tempos de profundas mudanças econômicas e sociais ocorridas no século XIX na Europa é quase que insignificante. Valendo-nos dos aportes do materialismo histórico e dialético, analisamos as contribuições de A situação da classe trabalhadora na Inglaterra, de Friedrich Engels, para a compreensão do tema. Tendo como fundamento os aportes da obra clássica de Engels, o estudo conclui que é possível visualizar uma nova configuração do conceito e de um novo sentimento de infância, de natureza materialista e não idealista, baseado fundamentalmente no papel que coube às crianças proletárias em tempos de mudanças sociais.

Objective. To perform interim analysis of epidemiological parameters of COVID-19 in the Russian Federation. Material and methods. The article is based on the analysis of individual monitoring data carried out by Federal Service for Surveillance on Consumer Rights Protection and Human Wellbeing for January–June 2020. Results. The epidemic process in Moscow and Moscow region (MR) differed from that in other regions. In Moscow and MR,daily increase of new coronavirus cases was characterized by high absolute numbers and varied between 5.0% and 29.2% in March–April 2020. The peak (7,446 new cases) was registered on May 6; after that, the number of new cases was rapidly declining and decreased by 84.9% from the peak value by June 30. This was ensured by strict restrictive measures and effective control in Moscow and MR. In other regions, daily increase of new cases varied between 2.9% and 52.6%. The peak incidence was registered on May 21 (6,021 new cases), whereas the plateau phase was observed between May 14 and June 17, 2020 (5,808–6,021 new cases daily). Only by June 28, the number of new cases decreased by 43.8% from the peak value. During this time, the number of new cases in Moscow and MR was already 3 times lower. This can be explained by less severe restrictions in other regions. Half of patients (50.1%) had mild disease. The majority of patients were aged 41–64 (44.4%) and 18–40 years (30.2%). In the age group ≥40 years, women prevailed; however, they usually had milder disease, which was observed in all age groups ≥18 years. Conclusion. The characteristics of the epidemic process in Russia were largely determined by the restrictive measures introduced in March 2020. These measures significantly reduced both the epidemic intensity of COVID-19 and the role of children of various age groups in it. The earlier start of active circulation of SARS-CoV-2 in Moscow and MR, as well as its subsequent spread to the regions by labor migrants who returned from the capital led to a significant difference in the dynamics of new cases at the decline of the epidemic. Key words: age groups, COVID-19, Russia, severity, epidemic process.

Internet-of-things (IoT) systems, covering any type of application, are becoming increasingly important. The most important network infrastructure used for the development of IoT applications is the Wi-Fi network, as it is widespread and provides greater freedom during installation. There are cases where the cost of building the Wi-Fi infrastructure or the specific field of use do not justify the adoption of this network standard. The following study proposes the use of the powerline network as an alternative to Wi-Fi for the realisation of IoT systems. An IoT system for the monitoring of pulse oximeter values in a hospital setting will be described and discussed. The novelty of the proposed system is the adoption of powerline communication for the medical environment

Three hundred and twenty-eight myopic children, randomized to use either 0.01% (N=166) or 0.02% (N=162) atropine were enrolled in this study. Gender, age, body mass index(BMI), parental myopia status, atropine concentration used, pupil diameter, amplitude of accommodation, spherical equivalent refractive error (SER), anterior chamber depth (ACD) and axial length (AL) were collected at baseline and 1 year after using atropine. Rapid AL elongation was defined as >0.36 mm growth per year. Univariate analyses showed that children with rapid AL elongation tend to be younger, have a smaller BMI, use of 0.01% atropine, narrow ACD, lower SER, shorter AL, smaller change in pupil diameter between 1 year and baseline (all P < 0.05). Multivariate regression analyses confirmed that rapid AL elongation was associated with children that were younger at baseline (P < 0.0001), use of 0.01% atropine (P = 0.04), a shorter baseline AL (P = 0.03) and a smaller change in pupil diameter between 1 year and baseline (P = 0.04). Younger children with shorter AL at baseline, less change in their pupil diameter with atropine treatment and using the lower of the two atropine concentrations may undergo rapid AL elongation over a 12 months myopia control treatment period.

This work is an attempt to overcome antimicrobial resistance problem which dispersed worldwide inparticular developing countries due to misuse of antibiotics. Actinobacteria were isolated and screenedagainst selected resistant Gram-negative bacteria to detect the powerful antibacterial activity.Identification of the most potent actinobacterial isolate has been carried out using classical and geneticalmethods. Antibacterial compound has been extracted, purified and characterized using accurate and morespecific techniques and instruments. Among forty actinobacterial isolates, only twenty-two isolates couldinhibit the growth of Gram-negative bacteria. The most potent isolate Eg-7 was identified as S.griseorubens, which has a typical 16S rRNA gene. The antibacterial compound was extracted using ethylacetate, and separated by High Performance Liquid Chromatography using methanol and water as amobile phase. Five active peaks were displayed and retained in the range 40 – 45 min, but the last threepeaks were retained at 41.90, 43.43, and 44.54 min, respectively. The crude extract was analyzed byliquid chromatography mass spectrum, where the active peak was displayed at 721.325 m/z. Theantibacterial compound was purified using flash column chromatography and gel filtration columnchromatography. The active fraction was analyzed by Infra-Red spectrum, where a broad absorption at3338 cm-1 was displayed. Molecular formula of an antibacterial compound was determined by massspectrum as C35H26N6O4. Nuclear magnetic resonance analysis was carried out for an antibacterialcompound. These results suggest that a new antibacterial compound that similar quinolone could beproduced by S. griseorubens and exhibited a higher activity against Gram-negative bacteria.

There is some evidence that lactobacilli can strengthen immune system of chickens. This study evaluated the effects of in ovo and oral administration of a lactobacilli cocktail on cytokine gene expression, antibody-mediated immune response, and spleen cellularity in chickens. Lactobacilli were administered either in ovo at embryonic day 18, orally to hatched chicks at days 1, 7, 14, 21, and 28 post-hatches, or by both treatments combined. On days 5 and 10 post-hatch, spleen and bursa of Fabricius were collected for gene expression and cell composition analysis. On days 14 and 21 post-hatch, birds were injected with sheep red blood cells (SRBC) and keyhole limpet hemocyanin (KLH), and sera were collected on days 7, 14, and 21 post-primary immunization. Birds that received lactobacilli (107 CFU) via in ovo followed by weekly oral administration showed a greater immune response by enhancing antibody response, increasing the percentage of CD4+ and CD4+CD25+ T cells in the spleen, and upregulating the expression of the expression of interferon (IFN)-α, IFN-β, interleukin (IL)-12, and IL-13 in the spleen and expression of IFN-γ, IL-2, IL-6, IL-8, IL-12, and IL-18 in bursa. These findings suggest that pre-and post-hatch administration of lactobacilli modulate immune response in newly hatched chickens.
