Исследование динамики содержания малонового диальдегида в консервированном пюре из цветной капусты при различных режимах хранения
Authors: Самойлов Артем Владимирович , Сураева Наталья Михайловна , Рачкова Вера Павловна 
Published: August 2020

Послеуборочное хранение плодоовощной продукции сопровождается повышением перекисного окисления липидов в цитоплазматической мембране растительных клеток и увеличением концентрации малонового диальдегида, уровень которого сохраняется при дальнейшем консервировании. В организме человека этот альдегид также является продуктом окисления ненасыщенных жирных кислот и способен взаимодействовать с белками, ДНК и другими молекулярными структурами, образуя различные потенциально токсичные аддукты. К числу важных направлений изучения механизмов молекулярной нестабильности пищевых ингредиентов следует отнести изучение их взаимодействий с малоновым диальдегидом. Цель исследования – изучение влияния условий хранения консервированного пюре из цветной капусты на содержание малонового диальдегида. В работе использовали свежую цветную капусту и консервированное пюре из нее. Малоновый диальдегид определяли спектрофотометрическим методом по цветной реакции с тиобарбитуровой кислотой. Было показано, что уровень этого биомаркера в пюре не превышал аналогичных результатов измерений в свежей капусте. Было продемонстрировано линейное снижение уровня малонового диальдегида в пюре при хранении в течение более 4-х месяцев с высоким коэффициентом детерминации (R² = 0,9796) при комнатной температуре. Повышение температуры хранения консервированного продукта существенно повлияла на скорость деградации малонового диальдегида. Его концентрация снизилась почти на 10% по сравнению с контрольными образцами, которые хранились при комнатной температуре, однако этот эффект не возникал при условии периодического снижения температуры хранения до 4,0°С. В этом исследовании было обнаружено, что уровень малонового диальдегида в консервированных пищевых продуктах менялся в зависимости от сроков и условий хранения этих продуктов.

Пациенты с наличием сердечно-сосудистых заболеваний (ССЗ) представляют особую уязвимую группу населения в условиях пандемии коронавирусной инфекции COVID -19. Они наиболее подвержены риску заражения, тяжелому течению заболевания, а также более высокой летальности по сравнению со здоровой популяцией. В настоящее время отсутствуют рандомизированные клинические исследования, позволяющие определить наиболее эффективные подходы к лечению у данной категории больных. Представленный клинический пример демонстрирует возможности применения различных групп препаратов, рекомендованных для лечения COVID-19 и высокую эффективность терапии ингибитором рецептора интерлейкина – 6 (ИЛ-6) у пациента с тяжелым течением новой коронавирусной инфекции и наличием сопутствующей сердечно-сосудистой патологии.Patients with cardiovascular disease represent a particularly vulnerable population in a pandemic of the coronavirus infection COVID -19. They are more at risk of infection, a severe course of the disease, as well as a higher mortality rate compared to a healthy population. Currently, there are no randomized clinical trials to determine the most effective approaches to treatment in this category of patients. The presented clinical example demonstrates the possibilities of using various groups of drugs recommended for the treatment of COVID-19, and the high efficiency of treatment with an interleukin-6 receptor inhibitor (IL-6) in a patient with severe new coronavirus infection and the presence of concomitant cardiovascular pathology.

Published: August 2020

Externality; the term can define as a positive or negative impact from either production or consumption of goods or services. Services provided by particular location have very specific dependency on spatial characteristics of that region. A region’s distinct characteristics make it ecologically unique from other such regions. Ecosystem services offered by these regions thus differ according to these unique ecological features. In this particular study, artificially imposed expansion of coastal shrimp farming towards the inland and its impact over paddy cultivation have been addressed. Optimization of the extent of this manipulative coastal expansion has been supported by little modification of a previously described model. Here the investment prediction for both shrimp and paddy farming has been investigated by calculating net present value (NPV). Shrimp farming has very specific externality on local ecosystem services. In this particular case, some contradictory results are presented and with respect to positive or negative externality; but the externality are strong. NPV results indicate that there is no long-term profitability in case of shrimp farming. Hence, an overall externality of shrimp farming has been described in context of this study.
Sexualité limite et processus mélancolique
Authors: Mazoyer Anne-Valérie , Estellon Vincent , Roques Marjorie 
Published: August 2020

Chez une femme ayant subi un deuil maternel à l’âge de 8 ans, puis l’inceste paternel pendant des années et qui s’adonne, à l’âge adulte, à des pratiques sexuelles principalement sadomasochistes, sont mis en perspective les mouvements mélancoliques qui infiltrent des comportements sexuels compulsifs où humiliation et souffrance sont activement recherchées. À partir de cette étude de cas, est engagée une réflexion sur les modalités de transfert et de contre-transfert particuliers et leurs effets dans l’élaboration de la relation thérapeutique. Nous soumettons à la discussion l’hypothèse du masochisme pervers féminin qui relayerait le masochisme érotique féminin dans la sexualité compulsive.
Experimental Evaluation of Perfluorophenanthrene as a High Specific Gravity Vitreous Substitute: A Preliminary Report

Published: August 2020

ABSTRACT
Perfluorophenanthrene, a liquid fluorocarbon with a specific gravity approximately twice that of water, potentially offers certain advantages as a vitreous substitute in vitreoretinal surgery. To determine its efficacy and safety we first purified it by chemical methods used in the preparation of experimental blood substitutes to a level at which it was not at all or only minimally toxic to culture-grown retinoblastoma cells. Nineteen of 22 vitrectomized eyes of white New Zealand rabbits injected with this purified perfluorophenanthrene showed satisfactory clinical tolerance. Light and electron microscopy showed minimal or no toxic effects in the 19 eyes, although uptake of perfluorophenanthrene by some preretinal cells was observed 28 days after implantation. Postoperative light-adapted electroretinography recordings of eight of the injected eyes showed no significant change. Perfluorophenanthrene injected into the anterior chamber of the rabbit eyes had toxic effects on the cornea.
If further experimentations confirm our findings, perfluorophenanthrene may be a suitable transparent high-density liquid for temporary use in surgery to repair retinal detachments.

Published: August 2020

The ePortfolio has been used extensively in education in various countries and for diverse career paths. It is a dynamic platform that students can use to compile and formulate a digital presentation using different types of media which can be updated and adapted for distinct purposes and audiences. Because the ePortfolio is, by nature, flexible and adaptable, it can be developed over the course of a student’s studies and be easily incorporated into professional networking platforms as a job search tool. The objective of this study was to assess and compare the willingness of school principals from Poland and Spain to use the ePortfolio as a hiring tool. The authors also sought to ascertain whether the number of employees in the participants’ schools or previous contact with ePortfolio affected their opinion of it as a hiring tool. Participants took a survey after reviewing examples of career ePortfolios, and their answers were tabulated and analyzed. The results show that principals from both countries would be inclined to use the ePortfolio as a hiring tool, and that neither previous contact nor number of employees significantly affected their opinion. These results are significant as they demonstrate a broad willingness to implement the ePortfolio as a hiring tool, that was not significantly affected by country or size of school. It is also relevant that this broad support was shared by principals who were unfamiliar with the ePortfolio before participating in this study.

Background:
Osteoporosis and sarcopenia are important aspects of motor neuron disease (MND). Individuals with amyotrophic lateral sclerosis (MND-ALS) have an increased risk of falls and fractures. Currently, the standard of care does not involve a routine assessment of bone mineral density (BMD) and body composition in these patients. We aimed to assess BMD, bone mineral parameters and body composition in men with MND and compared them with healthy controls.

Methods:
Consecutive males between 50 and 80 years of age diagnosed as MND-ALS by revised El Escorial criteria and able to walk unassisted attending Neurology outpatient clinic were recruited into the study. Age, gender and body mass index (BMI) matched healthy controls were recruited from the local community. BMD and body composition were assessed by dual-energy x-ray absorptiometry (DXA). Bone mineral parameters and bone turnover markers (BTMs) were also assessed in them.

Results:
A total of 30 subjects with MND-ALS and 33 controls were recruited. The mean age (years) was 59.2 in cases and 61.2 in controls. The mean BMD (g/cm2) between the two groups was similar; however, BTMs were significantly higher in the MND group (P < 0.05). Subjects with MND-ALS had significantly lower mean appendicular lean mass (ALM) (19.9 versus 22.4 kg; P = 0.007) and ALM corrected for BMI than the healthy control group (0.858 versus 0.934 kg/kg/m2; P = 0.034). Sarcopenic obesity (Percentage fat mass >27% + ALM/BMI <0.786 kg/kg/m2) was more prevalent in MND-ALS compared to controls (44.5% versus 16.7%; P = 0.03).

Conclusion:
Although BMD was not significantly different between subjects with MND-ALS and healthy controls, BTMs were significantly higher in the MND group indicating a high bone turnover state. Sarcopenia and sarcopenic obesity were also more in MND-ALS group than controls. Routine assessment for bone health parameters and body composition indices may be included in management of the patients with MND.

Abstract. In the framework of the EU Copernicus programme, the European Centre for Medium-Range Weather Forecasts (ECMWF) on behalf of the Joint Research Centre (JRC) is forecasting daily fire weather indices using its medium-range ensemble prediction system. The use of weather forecasts in place of local observations can extend early warnings by up to 1–2 weeks, allowing for greater proactive coordination of resource-sharing and mobilization within and across countries. Using 1 year of pre-operational service in 2017 and the Fire Weather Index (FWI), here we assess the capability of the system globally and analyse in detail three major events in Chile, Portugal and California. The analysis shows that the skill provided by the ensemble forecast system extends to more than 10 d when compared to the use of mean climate, making a case for extending the forecast range to the sub-seasonal to seasonal timescale. However, accurate FWI prediction does not translate into accuracy in the forecast of fire activity globally. Indeed, when all fires detected in 2017 are considered, including agricultural- and human-induced burning, high FWI values only occur in 50 % of the cases and are limited to the Boreal regions. Nevertheless for very large events which were driven by weather conditions, FWI forecasts provide advance warning that could be instrumental in setting up management and containment strategies.
Interdisciplinary Exploration Clarifying Barriers Hindering Minority Achievement
Authors: Ambrose Don 
Published: August 2020

ABSTRACT
Millions of young people from minority populations suffer from deprivation, segregation, and stigmatization. While a number of scholars have been doing impressive work revealing the nature and nuances of these problems, interdisciplinary investigation can reveal some additional nuances of the phenomena they are studying as well as other phenomena that haven’t yet been considered in depth and detail. This analysis brings together theories and research findings from multiple academic disciplines and professional fields and suggests ways in which the findings could strengthen awareness of the issues deprived young people confront as they move toward adulthood. Topics addressed in the article include the importance of ethical awareness, confined notions of morality, the increasing severity of socioeconomic inequality, and various forms of dogmatic self-deception that prevent the development of widespread ethical thought and action aimed at solving the problems faced by minority youth.

Published: August 2020

O presente artigo tem como objetivo problematizar as compreensões acerca da função social da escola, apresentada por graduados em cursos de licenciatura de diversas regiões do Brasil. Por meio de formulário online, foram coletadas cinquenta e seis respostas que são analisadas e problematizadas, tendo como base sua análise e categorização. O estudo mobiliza-se por meio de um ensaio com inspirações de Larrosa (2003), conjecturando o percurso de investigação a que se propõem os autores. Emerge do estudo, cinco categorias de análise: cidadania; ensino de conteúdo; mão de obra/formação para o mercado de trabalho; formação humana e integral; sem função social (todas com possíveis compreensões da educação como um direito humano). As categorias foram atentamente problematizadas, a partir de autores e pesquisadores que nos servem de inspiração para pensar o campo da educação e/ou escolarização. Desta pesquisa, resultam as mais diversas noções de função social da escola no contemporâneo.
Quando o acesso é o menor dos problemas: o direito ao espaço escolar de qualidade
Authors: Esquinsani Rosimar Serena Siqueira 
Published: August 2020

O texto parte da seguinte premissa: conquistar uma vaga na escola pública é parte do direito à educação, mas tal direito só estará completo se a vaga se fizer acompanhada por referenciais de qualidade, entre os quais, uma infraestrutura adequada. Para problematizar a qualidade do espaço escolar, apresenta como pano de fundo, parte dos dados publicizados pela pesquisa da UNESCO (ALVES; XAVIER, 2019) sobre a infraestrutura das escolas. Metodologicamente, trata-se de um texto analítico-reconstrutivo de base bibliográfica (revisão temática), cotejado por informações censitárias. O texto coloca a questão da qualidade, na educação, como um tema político, que perpassa por espaços adequados, com o mínimo de infraestrutura, higiene e segurança. Conclui que a consecução de um direito não está descolada de condições contextuais e objetivas que garantam sua efetividade, para além de declarações e intenções. Portanto, é preciso ir além da vaga: garantir a permanência, o sucesso escolar e um padrão mínimo (digno) de qualidade na escola.
Calcium and Metabolic Bone Disorders
Authors: Oladunni Ale Ayotunde , Akande Oluwayomi , Da Rocha-Afodu David 
Published: August 2020

Calcium homeostasis has a pivotal role in regulating many biological processes. The interplay of calcium-regulating hormones, including parathyroid hormone (PTH), vitamin D, and calcitonin, is crucial in tightly maintaining serum calcium levels. Deregulation of calcium homeostasis has clinical implications resulting in hypercalcemia or hypocalcemia, which can lead to metabolic bone disease (MBD). MBD is a group of multifactorial bone diseases, caused by bone demineralization and characterized by an increased susceptibility to fracture risk. This chapter aims to provide an overview of associated risk factors and diagnostic, prevention, and recent treatment methods for MBD. The diagnosis of MBD is based on the assessment of clinical signs, radiological findings, quantitative ultrasonography, and biochemical evaluation of serum calcium, phosphate, PTH, alkaline phosphatase, and vitamin D. Current pharmacological treatments include antiresorptive and anabolic conventional therapies. Additionally, the efficacy of herbal extracts and nutritional supplements have been evaluated. Recent advances in the MBD management include drugs targeting calcium-sensing receptor and parathyroid hormone-related proteins, leading to the development of cathepsin K and Src tyrosine kinase inhibitors, calcilytics, and monoclonal antibodies against sclerostin or Dickkopf-1. Moreover, new nanomaterials have been used for improving the surgical treatment of vertebral fractures.

Published: August 2020

Post operative infections that occur after surgical procedures can cause a lot of complications like sepsis, organ failure or even death. These are the third most commonly reported healthcare associated infection. The most common cause of wound infection regardless of procedure performed remains gram-positive cocci which comprise more than 50% of all infections. Specifically, Staphylococcus aureus and coagulase-negative staphylococci are the most frequent organisms isolated from a wound infection. There has been an increasing incidence of MRSA strains reported in hospitals across the globe. The main aim of our study is isolation, detection and molecular characterization of Staphylococcus aureus from postoperative infections. Samples were collected from post operative patients with infected wounds. The area around the wound was cleaned. Exudates were collected from the wound with a sterile swab stick. The samples were inoculated on different solid culture mediums and the plates were incubated in the presence of oxygen at 37°C overnight. There were many standard procedures done in which tube coagulase was taken as the main criteria. Antibiotic susceptibility testing was done by Kirby Bauer method following Clinical and Laboratory Standards Institute (CLSI) guidelines using commercially available cefoxitin (30 μg) disc (HiMedia) and the results were compared with Staphylococcus aureus ATCC 25923 and MRSA ATCC 43300 control strains. The MRSA strains were identified and detection of Mec A gene that codes for methicillin resistance is done using PCR technique.

These days people are more about how they look and are giving lots of importance to fitness. Aerobic exercise improves cardiovascular adaptations that increases the peak of oxygen consumption and increases the strength. This is more preferred than resistance exercise as it can be done at home. This study was a prospective observational study. The pros were easy to create. It has gathered large data, it is economical and it has quick interpretation. The cons were the homogeneous population and its survey fatigue. To minimize the sampling bias we have to minimize error in questions and avoid loading questions. This study contains 15 self-structured questionnaires which validated the study design, general population, methodology and its survey questionnaire are the internal validity. From the data analysis, the results showed that 95% feel it is good to do aerobics everyday and 5% feel it is not good to do aerobics everyday. 85% prefer walking is a good exercise and 15% prefer walking is not a good exercise. 85% feel aerobics tones our body, 15% feel aerobics does not tone our body. The aim of my study is to compare the effectiveness of aerobic and resistance exercise among the South Indian population.

Authors: Vivek K. 
Published: August 2020

Background: Platelet-rich plasma helps in repair because of its growth factor. Platelet-rich plasma has been used in humans for its healing properties. Increased concentration of growth factors and secretory proteins may increase the process of healing on a cellular level.
Aim: This study was done to check the effectiveness of PRP injections in patients with chronic lateral epicondylitis.
Methodology: This was accomplished in patients visiting the orthopaedic OPD at the Sree Balaji Medical College and Hospital, Chennai, Tamilnadu. There were 40 physicians in this study, among whom 37 were homosexual and 87 were female. The mean age of the patients was 48.1 years (17-82 years). The study period was 3 months. The analytical method used is a visual analog score.
Results: Effective therapy was performed with a decline of more than 20% (24 out of 40 patients) in visual analog score after a dual-month period. After 3 months in boys, the mean VAS score dropped from 6.88 to 9.41.
Conclusion: Medication of PRP patients with chronic epicondylitis or PRP tennis elbow reduces pain and increases the flexibility of the affected knee joint.
