Published: January 2019

Abstract
Rapid development in the field of tissue engineering necessitates implementation of monitoring methods for evaluation of the viability and characteristics of the cell cultures in a real-time, non-invasive and non-destructive manner. Current monitoring techniques are mainly histological and require labeling and involve destructive tests to characterize cell cultures. Bioimpedance measurement technique which benefits from measurement of electrical properties of the biological tissues, offers a non-invasive, label-free and real-time solution for monitoring tissue engineered constructs. This review outlines the fundamentals of bioimpedance, as well as electrical properties of the biological tissues, different types of cell culture constructs and possible electrode configuration set ups for performing bioimpedance measurements on these cell cultures. In addition, various bioimpedance measurement techniques and their applications in the field of tissue engineering are discussed.

Each of the above types had its own specificity in diagnosis, treatment and postoperative management of patients.Conclusion.Submucosal esophageal tumors vary in types of growth, sizes, number of tumors, localization and its relationship with the surrounding organs. Scrupulous diagnosis of each case is necessary which will allow choosing the most appropriate treatment tactics for the patient.
OS EFEITOS DA SUPLEMENTAÇÃO COM VITAMINA C
Authors: Santos Jordana Tres , Krutzmann Marise Wilsmann , Bierhals Camila Correa , Feksa Luciane Rosa 
Published: January 2019

A vitamina C ou ácido ascórbico (AA) é um elemento essencial para o ser humano e, por não ser metabolizado pelo corpo, necessitamos da sua ingestão pela dieta e/ou suplementação. As funções do AA no corpo são inúmeras, tais como: cofator para enzimas, biossíntese de hormônios e ação antioxidante, entretanto, estudos relatam que o consumo de AA em doses elevadas pode oferecer riscos à saúde. Deste modo buscou-se analisar os efeitos descritos da suplementação de AA. Realizamos uma revisão bibliográfica, dividida em duas perspectivas: uma histórica, com publicações de 1753-2012; e outra contemporânea, com estudos realizados entre 1990-2017. A pesquisa foi realizada no Science Direct, Scielo, PubMed, Scopus, Portal de Periódicos da Capes e em livros, utilizando as palavras-chave: vitamina C, ácido ascórbico, estresse oxidativo, antioxidante e pró-oxidante. A suplementação com AA é controversa, sendo descrito tanto o seu efeito antioxidante, como o pró-oxidante. A sua efetividade na prevenção e no tratamento do resfriado, diabete e câncer é questionável. Determinados grupos de pessoas mostram-se mais suscetíveis à toxicidade e aos danos do AA, podendo apresentar incidência de cálculos renais e interferência na função plaquetária. Concluímos que a suplementação em doses excessivas de AA pode ocasionar uma transição de um estado saudável para o patológico, desencadeando uma atividade pró-oxidante. Além disso, a dose ótima a ser ingerida e o limiar entre a dose benéfica e a prejudicial, é discutível. Desse modo, a suplementação de vitamina C deve ser realizada com cautela, com prescrição e acompanhamento de profissionais da saúde.

Will I ever connect with the students?” Online Teaching and the Pedagogy of Care
Authors: Adams Catherine , Rose Ellen 
Published: January 2019

Since Noddings (1984/2003) first made a case for acknowledging care as a core element and value in pedagogical relationships, research on care in classrooms has flourished.While research confirms the importance of a supportive environment for the success of the online student, we know little about how online instructors’ experience care—for their students and for themselves. This paper offers a phenomenological exploration of care as it is experienced in online postsecondary instructors’ interactions and relations with their students.
“Everywhere you go always take the weather with you”: Phenomenology and the pedagogy of climate change education
Authors: Howard Patrick 
Published: January 2019

In no other time in human history has the relationship between human beings, and the biosphere on which we depend, been fraught with such a sense of urgency. Responding to the imminent threat of climate change has focussed our attention on education. There has been a proliferation of international, national and regional programs designed to change attitudes, behaviours, and beliefs associated with the causes of climate change. This paper will look to phenomenology and pedagogy to attempt describe the experience of climate and to help us consider how we may allow the young to live in a time of inevitable climate disruption while nurturing what seems to come to them naturally, an embodied integration into the wonder and awe of the places they live. Also, this paper explores two dominant approaches to climate change education and asks how these approaches articulate an understanding of the essential relationship between humans and the larger living world as reflected through changing climatic conditions.

The purpose of the study is the development and implementation of a software system designed to automate the process of compiling a classroom schedule in the branch of the Transdniestrian State University. T.G. Shevchenko in Rybnitsa.
The object of the study is the automation of the formation of the schedule of classrooms.
The subject of the research is the implementation of a genetic algorithm as one of the adaptive search methods for solving functional optimization problems in order to automate the generation of a schedule.
At the stage of the research of the subject area, the methodology of scheduling in universities was studied. There are not so many developments in the automation of scheduling tasks. This suggests that this task is relevant and unified approaches to its solution still does not exist. A new approach to the implementation of solving the problem of finding the optimal schedule was the application of an expert approach based on the use of a genetic algorithm.
The authors describe the feasibility of using the genetic algorithm as one of the adaptive search methods for solving functional optimization problems in order to automate the formation of the schedule. Evaluating the work as a whole, it can be argued that the practical significance and prospects of development of this research direction is obvious.

Authors: Alfini Alfonso J. , Weiss Lauren R. , Nielson Kristy A. , Verber Matthew D. , Smith J. Carson 
Published: January 2019

Background: Exercise training has been associated with greater cerebral blood flow (CBF) in cognitively normal older adults (CN). Alterations in CBF, including compensatory perfusion in the prefrontal cortex, may facilitate changes to the brain’s neural infrastructure. Objective: To examine the effects of a 12-week aerobic exercise intervention on resting CBF and cognition in CN and those with mild cognitive impairment (MCI). We hypothesized individuals with MCI (versus CN) would exhibit greater whole brain CBF at baseline and that exercise would mitigate these differences. We also expected CBF changes to parallel cognitive improvements. Methods: Before and after a 12-week exercise intervention, 18 CN and 17 MCI participants (aged 61–88) underwent aerobic fitness testing, neuropsychological assessment, and an MRI scan. Perfusion-weighted images were collected using a GE 3T MR system. Repeated measures analyses of covariance were used to test within- and between-group differences over time, followed by post-hoc analyses to examine links between CBF changes and cognitive improvement. Results: At baseline, individuals with MCI (versus CN) exhibited significantly elevated perfusion in the left insula. Twelve weeks of aerobic exercise reversed this discrepancy. Additionally, exercise improved working memory (measured by the Rey Auditory Verbal Learning Test) and verbal fluency (measured by the Controlled Oral Word Association Test) and differentially altered CBF depending on cognitive status. Among those with MCI, decreased CBF in the left insula and anterior cingulate cortex was associated with improved verbal fluency. Conclusions: Exercise training alters CBF and improves cognitive performance in older adults with and without cognitive impairment. Future studies must evaluate the mediating effects of CBF on the association between exercise training and cognition.

BACKGROUND: Berries are important sources of crucial dietary components such as vitamins and minerals, as well as various phytonutrients that may be potentially beneficial to human health and could be used against chronic diseases including cancer and cardiovascular disorders. OBJECTIVE: The current study aimed to identify and analyze the 100 most cited papers related to berry research. METHODS: The Scopus database was searched to extract data. Two of the authors independently evaluated the manuscripts for relevance. Bibliometric data, including citation count, were analyzed together with the words in the titles and abstracts of the 100 most cited berry-related papers. RESULTS: Seventy-two of the 100 most cited papers were research articles. Most of them were published during the 2000s, and related to subject areas of agricultural and biological sciences ( n = 64), biochemistry, genetics and molecular biology ( n = 35), chemistry ( n = 29), medicine ( n = 24), and nursing ( n = 10). Journal of Agricultural and Food Chemistry was the dominating choice of publication outlet ( n = 26). CONCLUSIONS: Antioxidant and anticancer benefits appeared to be the major subject terms. Berries that were mentioned in at least 10% of the 100 papers were strawberry, blueberry, cranberry, raspberry, blackberry, bilberry, and grape berry. The review could provide a valuable guide for designing future studies based on berries, berry extracts, and bioactive compounds.
