Στην εργασία αυτή μελετήθηκε η μεταβολή της περιεκτικότητας του φυσικού χυμού πορτοκαλιού σε βιταμίνη C (ασκορβικό οξύ) ως συνάρτηση του χρόνου σε θερμοκρασία περιβάλλοντος για δύο διαφορετικά είδη χυμού: α) φυσικό χυμό πορτοκαλιού από πορτοκάλια που στύψαμε και β) από φυσικό χυμό του εμπορίου . Ο προσδιορισμός της περιεκτικότητας του πορτοκαλιού σε ασκορβικό οξύ έγινε με οξειδοαναγωγική ογκομέτρηση. Χρησιμοποιήσαμε διάλυμα KIO3/KI σε όξινο περιβάλλον και το τέλος της ογκομέτρησης ανιχνεύθηκε με την αλλαγή χρώματος λόγω προσθήκης διαλύματος αμύλου. Το Ι2 που παράγεται κατά την αντίδραση οξινισμένου με HCl διαλύματος KIO3, με διάλυμα KI , οξειδώνει το ασκορβικό οξύ σε δεϋδροασκορβικό οξύ. Όταν όλη η ποσότητα του ασκορβικού οξέος οξειδωθεί, τότε η περίσσεια του Ι2 που παράγεται από τη πρώτη αντίδραση, αντιδρά με τα ανιόντα Ι- που υπάρχουν ήδη στο διάλυμα και σχηματίζει σύμπλοκο με το άμυλο που έχουμε ήδη προσθέσει στο διάλυμα που ογκομετρούμε. Το σύμπλοκο αυτό έχει χαρακτηριστικό βαθύ μπλέ χρώμα. Τα αποτελέσματα της εργασίας αυτής έδειξαν ότι δεν μπορούμε να διατηρήσουμε έναν φρεσκοστυμμένο χυμό πορτοκαλιού ή έναν φυσικό χυμό πορτοκαλιού του εμπορίου σε θερμοκρασία περιβάλλοντος για κάποιο χρονικό διάστημα χωρίς να μειωθεί η περιεκτικότητά του σε βιταμίνη C. Η ελάττωση της περιεκτικότητας σε Βιταμίνη C για τα δύο είδη χυμού ήταν  62% και 66.7% αντίστοιχα μετά από χρόνο μίας εβδομάδας.

Σωστή ή λάθος η χρήση των tablets και των smart-phone στα σχολεία? Πώς επιδρά στις επιδόσεις των μαθητών?Αν επιχειρήσουμε να δώσουμε στην τεχνολογία μια θέση στην εκπαιδευτική διαδικασία, δηλαδή ως εργαλείο διερεύνησης και μάθησης και όχι ευκαιρία για διασκέδαση ή μέσο για άσκοπες πλοηγήσεις, τότε ίσως έχουμε μπροστά μας μία άλλη οπτική γωνία στη διδασκαλία. Προχωρήσαμε  λοιπόν σε μια απλή κατασκευή με  φτηνά μέσα και πολύ εύκολη χρήση που στηρίζεται στις ικανότητες των σύγχρονων κινητών και tablets και με τα οποία εξερευνούμε εύκολα το μικρόκοσμο που μας περιβάλλει. Η κατασκευή αυτή έγινε προκειμένου να μελετήσουμε ευμεγέθεις μικροοργανισμούς που ζουν στο θαλασσινό νερό και όχι μόνο. Φτιάξαμε ένα στερεοσκόπιο που μπορεί να χρησιμοποιηθεί στο σχολείο, στο φυσικό περιβάλλον και είναι εύκολο να χρησιμοποιηθεί από το νηπιαγωγείο μέχρι το λύκειο. Απλά υλικά από πλέξιγκλας και με αναζήτηση απλών φτηνών  φακών κατάλληλα επιλεγμένων και τοποθετημένων, προσέχοντας τη γεωμετρία της κατασκευής φτιάξαμε το στερεοσκόπιο που θα παρουσιάσουμε. Η αρχική ιδέα είναι γνωστή στο διαδίκτυο, αλλά σε απλή μορφή, με άλλα υλικά  και αμφίβολη χρήση. Η χρήση του στερεοσκοπίου που φτιάξαμε μας εξέπληξε και ξεπέρασε τα αναμενόμενα, δίνοντας  εξαιρετικές φωτογραφίες, βίντεο αλλά και την ικανότητα μέσω του διαδικτύου  να μεταφέρουμε όλα αυτά που είδαμε σε άλλους μαθητές και χρήστες, όπως η συνεργασία με το Σχολείο της Ίμβρου στη Τουρκία μέσω της τηλεδιάσκεψης. Αξιοποιώντας  τις νέες τεχνολογίες σε ομαδοσυνεργατικές εργασίες, πειραματιζόμαστε δημιουργούμε το δικό μας πολυμεσικό υλικό και το παρουσιάζουμε, ενώ αυτοαξιολογούμαστε από ειδικά διαμορφωμένες εφαρμογές μέσα από ένα εύχρηστο και προσβάσιμο περιβάλλον εργασίας.

Το θέμα της μελέτης μας είναι η επίδραση της θερμοκρασίας στη ποιότητα του θαλάσσιου οικοσυστήματος. Το συγκεκριμένο ερώτημα τέθηκε μετά μια επίσκεψη  μας στο εργοστάσιο της ΔΕΗ στη Μυτιλήνη και την παρατήρηση της απορροής του θερμού νερού της ψύξης των μηχανών στο παρακείμενο θαλάσσιο περιβάλλον. Είναι γνωστό από τη βιολογίας και χημεία ότι η άνοδος της θερμοκρασίας του νερού έχει ως αποτέλεσμα την μείωση της διαλυτότητας των αερίων στο νερό, άρα  και του Οξυγόνου και μας ενδιέφερε η υφιστάμενη κατάσταση του οικοσυστήματος. Προχωρήσαμε σε επιτόπια καταγραφή της υπάρχουσας κατάστασης με μετρήσεις θερμοκρασίας του νερού ψύξης των μηχανών από το σημείο απορροής,  σε επιλεγμένα σημεία του χειμάρρου, στο σημείο επαφής με το θαλασσινό νερό, αλλά και τη διασπορά του μέσα στο θάλασσα. Για της μετρήσεις χρησιμοποιήθηκε το Hydrobot με τους αισθητήρες Arduino, που κατασκευάσαμε με υλικά που μας παρείχε το Ίδρυμα Ευγενίδου αλλά και το σκάφος του Πανεπιστημίου Αιγαίου με τα όργανα του, σε συνεργασία με καθηγητές του Πανεπιστημίου. Με κατάλληλα όργανα μετρήσαμε τα θαλάσσια ρεύματα, ποντίζοντας το ρομπότ και παίρνοντας μετρήσεις με τους αισθητήρες , που μεταφέραμε στο κομπιούτερ για αξιολόγηση. Από τις μετρήσεις βρέθηκε μεγάλη άνοδο της θερμοκρασία του νερού σε τρία σημεία. Σε περαιτέρω αναζήτηση πληροφοριών επιβεβαιώθηκε για πρώτη φορά εργαστηριακά η ύπαρξη υποθαλάσσιων θερμών πηγών με θερμοκρασία 500  περίπου

Open Schooling in the Netherlands
Authors: Howaard Jay , Mataheru Rob
Published: September 2019

Here in the Netherlands the main idea about education has been to lock students up in schools and feed them with a lot of information. This has proven to be good method for achieving good exam results, however, students are lacking experience with society. That is why more and more schools are trying to become an open school – a school which seeks connection with the society. There are a lot of ways for schools to interact with society, in this case we will be looking at how two schools, one primary (De Verwondering in Monnickendam) and one secondary (Pieter Groen College in Katwijk), do just that.

Background: Non-communicable diseases (NCDs) are the leading cause of death worldwide and are a major burden in Tajikistan. The health system of Tajikistan is still shaped by the country's Soviet legacy and the pace of reform has been slow, with high patient out-of-pocket expenditure. The aim of this study is to determine the feasibility of implementing and evaluating essential interventions for the management of hypertension and prevention of cardiovascular disease in primary health care in Tajikistan.

Methods and analysis: A pragmatic, sequential mixed methods explanatory design, composed of quantitative and qualitative strands will be used with greater weighting of the quantitative strand. A single geographic district was nominated by the Ministry of Health and chosen for implementation. All primary health care centres in the district that meet inclusion criteria will be included; half will be randomly assigned to the intervention arm and half to the control arm. The overall process is organized into seven steps: (1) refresh clinical decision-making tools including open source WHO PEN and HEARTS resources; (2) update training package for primary health care workers; (3) collection of baseline data; (4) training staff in intervention clinics; (5) implementation of protocols and implementation coaching; (6) collection of follow-up data after 12 months; (7) evaluation of results and sharing experience.

Ethics and dissemination: Ethical review and approval have been obtained. Findings will be disseminated at the participant level, national level through a national conference of key stakeholders, and internationally through publication in an open-access peer review journal.
Case Report: Exploratory treatment with multiple intravenous infusion of the autologous adipose tissue-derived mesenchymal stem cells for the treatment of Diamond-Blackfan anemia patient
Authors: Ra Jeong Chan , Park Jong Im , Yang Pil Soon
Published: September 2019

Diamond-Blackfan anemia (DBA) is a rare congenital erythropoietic disorder characterized by erythroblastopenia. Conventional treatments of DBA are the administrations of corticosteroids and blood transfusions for mitigation of anemia, and bone marrow transplantation. However, there are hurdles to overcome for long-term use and the conventional treatment. Mesenchymal stem cells (MSCs) have been noted as a novel alternative cell therapy in various diseases, and adipose tissue-derived MSCs (AdMSCs) are known for their versatile efficacies and feasibility. Here, we report the potential efficacies and the safety of intravenous administration of the autologous AdMSC in a patient with DBA for the first time. The isolation and characterization of autologous AdMSCs from a girl aged 11 years, 10 months with DBA were carried out due to the mutation of ribosomal protein s24 (RPS24). AdMSCs, diluted to 1 x 108 cells in 100 ml of saline, were infused intravenously for 1 hour. Intravenous administration of AdMSCs was carried out 5 times in 2-week intervals, and the patient was checked using various assessments (vital signs, physical examination, laboratory tests, adverse events, etc) at every visit. After 3, 6 and 9 months from the first administration of AdMSCs, red blood cell (RBC) count, hemoglobin value, and hematocrit were assessed for the efficacy. There were no side effects or adverse events observed during the treatment. Although showing subnormal values, the RBC number, hemoglobin level, and hematocrit were improved 9 months after the systemic administration of AdMSCs from baseline; the RBC count (x106 /μl), hemoglobin level (g/dl) and hematocrit level (%) were increased from 1.58 to 2.38, 5.6 to 8.3, and 16.9 to 26.1, respectively. The present case reported the first AdMSC administration for DBA patient and indicates it is possible that the intravenous administration of autologous AdMSC can be a safe alternative for DBA treatment.
The fertility impact of achieving universal health coverage in an impoverished rural region of Northern Ghana
Authors: Phillips James F. , Jackson Elizabeth F. , Bawah Ayaga A. , Asuming Patrick O. , Awoonor-Williams John Koku
Published: September 2019

Background:  When a successful Navrongo Health Research Centre service experiment demonstrated means for reducing high fertility and childhood mortality in a traditional societal setting of northern Ghana, the Ministry of Health launched a program of national scaling up known as the Community-based Health Planning and Services (CHPS) initiative. For two decades, CHPS has been Ghana’s flagship program for achieving universal health coverage (UHC). When monitoring during its first decade determined that the pace of CHPS scale-up was unacceptably slow, the Ghana Health Service launched the Ghana Essential Health Interventions Program (GEHIP) in four Upper East Region districts to test means of accelerating to CHPS implementation and improving its quality of care.  

Methods:  To evaluate GEHIP, a two-round randomized sample survey was fielded with clusters sampled at baseline that were reused in the endline to facilitate difference-in-difference estimation of changes in fertility associated with GEHIP exposure.  Monitoring operations assessed the location, timing, and content of CHPS primary health care. Discrete time hazard regression analysis on merged baseline and endline birth history data permit estimation of GEHIP fertility and CHPS access effects, adjusting for hospital and clinical service access and household social and economic confounders. 

Results: GEHIP exposure was associated with an immediate acceleration of CHPS implementation and coverage. Women residing in households with CHPS services had only slightly lower fertility than women who lacked convenient access to CHPS. GEHIP impact on contraceptive use was statistically significant but marginal; GEHIP exposure was associated with increasing unmet need. 

Conclusion: Results challenge the assumption that achieving UHC will reduce excess fertility.  Social mobilization, community-outreach, connection of family planning discussions with male social networks are elements of the Navrongo success story that have atrophied with CHPS scale-up.  Achieving UHC does not address the need for renewed attention to these family planning focused strategies.

Features of Management in Terms of Digitization
Authors: Левчаев Петр , Levchaev Petr , Хезазна Бадар , Hezazna Badar
Published: September 2019

The article presents a comparative study of the classical views of management in the conditions of intensification of the processes of digitalization and construction of the "digital" model of the world. The conclusion is made about a radical change of the management paradigm and depersonalization of highly effective processes of management of various focus groups by formalized algorithmized commands of artificial intelligence. In the conditions of intensification of the processes of digitalization and use of artificial intelligence (AI) in the daily life of consumers of services and different groups of users, the problems of interactions between the control and managed subsystems are of priority importance, since they directly actually affect not only all behavioral characteristics of the individual in the digital economic way, but also in the existing social way. The resonant statement of our President at the St. Petersburg forum that the leader in the development of AI can become the ruler of the world testifies to the special importance of the problem of governance in the context of the development of post-industrial society and the formation of the information environment of the digital society.
Transfer Pricing System Based on the Method of Cash Flows Redistribution
Authors: Ребров С. , Rebrov S.
Published: September 2019

The article describes the system of transfer pricing based on the method of cash flows redistribution, developed by the author. The article describes such concepts as transfer price, transfer pricing, transfer pricing system. Methodological tools of research: analysis, synthesis, system approach. The author used the method of cash flows redistribution, the description of which is given in this article. The transfer pricing system developed by the author is based on the determination of the transfer price interval on the basis of the transfer pricing methods allowed by tax law, as well as the average value of this interval. This average value can be considered as the average market price, which is determined by the specifics of transfer pricing methods. If there is a deviation from the average market price, there is a redistribution of funds between the subjects of the transaction. For the control of transfer price introduced the coefficient of cash flows redistribution. To manage the transfer pricing system, a matrix of cash flow redistribution coefficients was introduced, as well as the account "redistributed funds". The positive and negative consequences of the introduction of this system of transfer pricing are considered.

Modern Approaches to the Development of Personnel Management System: the Choice of Methods and Criteria for Evaluating the Effectiveness of Personnel Training
Authors: Маликов Р. , Malikov R. , Исакова П. , Isakova P. , Карпеева В. , Karpeeva V.
Published: September 2019

The article discusses the model of professional training of enterprise personnel, potential personnel training pitfalls, tools and criteria for evaluating the effectiveness of training. A matrix for selecting a personnel training method and a scheme for evaluating the effectiveness of personnel training are proposed. In today’s rapidly developing conditions to ensure the stability of the enterprise and increase the level of competitiveness, an important factor is the professional development of personnel, which must comply with the conditions of the internal and external environment. An important resource of each enterprise is highly qualified personnel, able to fulfill all the goals and objectives set for it. The staff performance is one of the indicators that affect the success of the enterprise. Proper investment in staff training will ultimately provide a solid, motivated, qualified staff that will bring profits to the company, as well as reduce staff turnover and ensure the growth of the productivity of each employee. For the effective functioning and development of the enterprise, management needs to create a constantly learning organization that is able to adapt to external changes and is ready to master innovative work methods and technologies to solve real problems of the company. Therefore, there is a need for new knowledge, the development of special skills and innovative approaches to the implementation of their professional duties. To do this, the management of the enterprise needs to systematically and purposefully send employees for training and retraining so that the acquired professional knowledge will contribute to the solution of the previous tasks in new non-standard, more efficient ways.
How Do You Search for the Best Alternative? Experimental Evidence on Search Strategies to Solve Complex Problems
Authors: Sommer Svenja C. , Bendoly Elliot , Kavadias Stylianos
Published: September 2019

Through a controlled two-stage experiment, we explore the performance of solution search strategies to resolve problems of varying complexity. We validate theoretical results that collaborative group structures may search more effectively in problems of low complexity but are outperformed by nominal structures at higher complexity levels. We call into question the dominance of the nominal group technique. Further close examination of search strategies reveals important insights: the number of generated solutions, a typical proxy for good problem-solving performance, does not consistently drive performance benefits across different levels of problem complexity. The average distance of search steps and the problem space coverage also play critical roles. Moreover, their effect is contingent on complexity: a wider variety of solutions is helpful only in complex problems. Overall, we caution management about the limitations of generic, albeit common, rules of thumb, such as “generate as many ideas as possible.”

Different Learners: Why Music and Movement are Brain Food for Every Child
Authors: Healy Jane M.
Published: September 2019

I was pleased and honored to present the keynote address at this summer’s Music and Movement Conference. As always, the music professionals were a wonderful audience with thoughtful questions which demonstrated not only their deep concern for children’s needs, but also an impressive background of information on children’s healthy development—both cognitive and emotional. Following is a brief summary of the two sessions: In Part I we investigate the fascinating puzzle of how genetics and environments interact for abilities, talents, and problems; in Part II we address the dazzling plasticity of the growing brain and how targeted experience can help wire—and re-wire—neural systems for optimal development. (As the mother of a professional musician, I have a special interest in such research!) All this material is adapted from my new book, Different Learners: Identifying, Preventing, and Treating Your Child’s Learning Problems (Simon & Schuster, 2010).
Zur höchsten Zahl der Aktanten von verbalen Valenzträgern
Authors: Uzonyi Pál
Published: September 2019

In der Studie wird zuerst der Frage nachgegangen, ob die Termini Aktant, Ergänzung und Komplement in jedem Fall koreferent sind. Argument wird nur selten als deren Synonym verwendet, zumeist wird es auf der tieferen Ebene der Prädikat-Argument-Strukturen verortet. Stelligkeit wird vornehmlich auf Prädikate, Wertigkeit auf Valenzträger, insbesondere Verben bezogen. Wenn eine Valenzdimension exklusiv angewendet wird, z.B. Subklassenspezifik, kann die Zahl der Leerstellen 7 oder mehr erreichen, während eine Kombination von Obligatorik, Impliziertheit und Subklassenspezifik ein Maximum von 5 Mitspielern zulässt. Die Einbeziehung von Kasusrektion als Valenzdimension kann die Wertigkeit erhöhen, wenn sie der Impliziertheit übergeordnet wird.

Postcholecystectomy biliary clip migration is a rare but important cause of acute pancreatitis (AP). We report the case of a patient with laparoscopic cholecystectomy for cholelithiasis with cholecystitis and recurrent AP 15 and 19 months after. Imaging findings were suggestive of biliary clip migration. Suspected mechanisms for endoclip migration–induced AP include migration of the clip at a site of dehiscence and migration. When considering this diagnosis, a plain radiograph may be helpful as a comparison to previous imaging to assess for changes in the number of endoclips present, and proper diagnosis can help lead to appropriate management.
DOGMA TRITUNGGAL MENURUT KRISTEN SAKSI-SAKSI YEHUWA
Authors: Ismail Roni
Published: September 2019

In the tradition of mainstream Christianity, the Trinity is a very central dogma as a faith in God as the Father, the Son, and the Holy Spirit. It can be seen in the 12 creeds of the Apostolic Creed where the faith of the Trinity was first, second, and third. There is one school of Christianity, calling themselves Jehovah's Witnesses, rejecting the dogma of the Trinity in their divine concept. According to Jehovah's Witnesses, the word Trinity is not originated of the Bible. The Trinity is also not taught by early Christian Fathers and Pre-Nicene. The Trinity Dogma was introduced by Constantine for some reasons, and even continued in the Athanasian Creed. Jehovah's Witnesses therefore believe that the Trinity dogma is an apostate that the Bible has foretold, and is influenced by ancient beliefs and Platonism.

Introduction: Nowadays, prevalence of metabolic syndrome (MetS) is increasing in the world. There are inconsistence findings about the relationship between food insecurity and MetS. Therefore, the aim of this cross-sectional study was to determine the association between food insecurity and MetS in North West of Iran. Methods: The anthropometric measurements, food insecurity, dietary intake, blood pressure, fasting blood glucose (FBS), serum triglyceride and HDL levels of 151 subjects who had participated in Azar cohort study were evaluated. Food security was assessed by Household Food Security Scale (HFIAS) (six-item short questionnaire) and dietary intake (using 24- hour recall questionnaire) of participants. MetS was defined according to National Cholesterol Education Program’s Adult Treatment Panel III report (ATPIII) criteria. Results: On the basis of HFIAS and energy, 7.3% and 11.9% of participants were food insecure and hunger, respectively. We observed no significant differences in mean body weight, BMI, waist circumference and FBS between food insecure and secure groups. Moreover, obesity (41.7% vs 30.2%) and MetS (45.5% vs 30%) were more prevalent in the food insecure group but the differences were not significant. Conclusion: The most percent of participants in food insecure were obese and had MetS. However, we could not find significant differences between food insecure and food secure groups. Therefore, for achieving more clear results, further studies with large sample size are needed.

Introduction: Cardioembolic events are accompanied by left atrial appendage (LAA) in patients suffering from atrial fibrillation (AF); therefore, the LAA closure is implemented as a preventive strategy. The detection of LAA morphologies and function is a paramount step before establishing the LAA closure. Herein, we sought to determine the morphologic features of the LAA in an Iranian population using echocardiographic evaluation. Methods: Seventy-two near-normal heart patients were investigated by conducting a cross-sectional study. All patients were examined using the 2-dimensional and 3-dimensional transesophageal echocardiography (2D- and 3D-TEE) method. The anatomical features and functions of LAA were examined. All images were stored and analyzed offline. Results: The patients’ mean age was 39 ± 15.5 year and 33 (45.8%) were female. The most frequent shape of LAA was wind sock. More LAA lobes was observed in patients with AF compared to those with NSR. In comparison with AF group, the NSR had higher LAA flow velocity (P < 0.01). The paroxysmal AF had greater LAA flow velocity and LAA ejection fraction in comparison with the chronic AF (39 ± 19 vs. 75 ± 22, P < 0.01; and 49±4 vs. 72±14, P < 0.003; respectively). The paroxysmal AF had smaller systolic LAA orifice area in comparison with the chronic AF (P < 0.02). Conclusion: The morphologic features of LAA in Iranian population were within the range of other studies and LAA length and orifice diameters in 2D- and 3D-TEE were consistent. In addition, AF influenced the morphologies and functions of LAA compared to sinus rhythm.
Effect of Holes Drilled Various Distances from the Edge of Douglas Fir Utility Poles Tested in Bending

Published: September 2019

Wood utility poles are one of the most critical components of U.S. infrastructure. In the Pacific Northwest, Douglas fir is the species of wood predominantly used. Douglas fir has a relatively thin band of treatable sapwood surrounding an impermeable, but only moderately durable, heartwood core that is susceptible to internal decay. Historically, through boring has been the most commonly adopted practice for improving the performance of Douglas fir poles. Despite the inclusion of through boring in national utility standards, questions continue to rise regarding through boring. One important question regarding the process is how close to the edge holes should be drilled. The objective of this study was to assess the effects of through boring edge distance on the flexural strength of Douglas fir poles using a combination of full-scale flexural testing of poles as well as finite element analysis (FEA). Full-scale testing of 48 utility poles revealed that drilling holes within 50 or 75 mm of the outer edge of a pole had no significant effect on flexural properties. FEA consistently predicted failure modes and flexural properties after accounting for through boring and knot locations. These models could be improved through more accurate representation of grain around knots and then used to explore the effects of different sizes, species, quantities of knots and checks, and other drilling patterns on strength, and, therefore, would reduce the need for actual physical testing.
Investigation of Disintegration Behaviors of Clay-Bearing Rocks by a New Methodology

Published: September 2019

Disintegration behaviors of clay-bearing rocks are special engineering problems. Samples are isolated and unconstrained in previous disintegrating-durability tests, unlike clay-bearing rocks under the natural controlled condition in the field. Then, a methodology of disintegration testing regarding natural controlled conditions was evaluated to study the disintegration behaviors of clay-bearing rocks. The study results indicated that the fissure area ratio (FAR) increases rapidly before the seventh wetting-drying cycle and then begins a stable trend. The fragment size distribution characteristics show that the proportion of small fragments gradually increases and that the proportion of large fragments gradually decreases with the increase in the number of wetting-drying cycles. Clay-bearing rock fragments larger than 2 mm disappear after seven wetting-drying cycles. The change characteristics of the disintegration resistance of the disintegrating clay-bearing rock are that, regardless of the critical fragment size diameter (Dcr) of complete disintegration, the slake durability index (I(D)) and disintegration ratio (DR) are reduced. The disintegration degree of aggregate fragments is further reflected by the DR, which corresponds with the FAR. A trend of the maximum shear stress related to the number of wetting-drying cycles has two stages: the first significant and then insignificant decrease. The critical number of wetting-drying cycles is seven, after which point the disintegrating clay-bearing rock fragments with a size coarser than 2 mm disappeared. The results indicate the highly positive correlation between strength and the DR of the disintegrating clay-bearing rock.

Reduction of the dendritic arbor length and the lack of dendritic spines in the pyramidal cells of the prefrontal cortex (PFC) are prevalent pathological features in schizophrenia (SZ). Neonatal ventral hippocampus lesion (NVHL) in male rats reproduces these neuronal characteristics and here we describe how this is a consequence of BDNF/TrkB pathway disruption. Moreover, COX-2 proinflammatory state, as well as Nrf-2 antioxidant impairment, triggers oxidative/nitrosative stress, which also contributes to dendritic spine impairments in the PFC. Interestingly, oxidative/nitrosative stress was also detected in the periphery of NVHL animals. Furthermore, risperidone treatment had a neurotrophic effect on the PFC and antioxidant effects on the brain and periphery of NVHL animals; these cellular effects were related to behavioral improvement. Our data highlight the link between brain development and immune response, as well as several other factors to understand mechanisms related to the pathophysiology of SZ.

SIGNIFICANCE STATEMENTPrefrontal cortex dysfunction in schizophrenia can be a consequence of morphological abnormalities and oxidative/nitrosative stress, among others. Here, we detailed how impaired plasticity-related pathways and oxidative/nitrosative stress are part of the dendritic spine pathology and their modulation by atypical antipsychotic risperidone treatment in rats with neonatal ventral hippocampus lesion. Moreover, we found that animals with neonatal ventral hippocampus lesion had oxidative/nitrosative stress in the brain as well as in the peripheral blood, an important issue for the translational approaches of this model. Then, risperidone restored plasticity and reduced oxidative/nitrosative stress of prefrontal cortex pyramidal cells, and ultimately improved the behavior of lesioned animals. Moreover, risperidone had differential effects than the brain on peripheral blood oxidative/nitrosative stress.

Background & Aims: Modulation of the gut microbiota emerges as a therapeutic possibility to improve health. Our objective was to compare the impact of three months of intervention with diet plus nutritional orientation versus only nutritional orientation on the gut microbiota and metabolic-nutritional profile of outpatients with non-alcoholic steatohepatitis.

Methods: It was a randomized clinical trial with 40 outpatients (49.48 ± 10.3 years), allocated in two groups: DIET group (n=20), who received diet (1.651.34 ± 263.25 kcal; 47% carbohydrates, 28% lipids, 25% proteins, 30 g fibers) and nutritional orientation, and control group (n = 20), which received only nutritional orientation.

Results: The DIET group, in relation to baseline, presented a reduction in body weight (p<0.001), BMI (p<0.001), waist circumference (p=0.001), percentage of fat (p=0.002), serum aspartate aminotransferase (p<0.001), alanine aminotransferase (p<0.001), γ-glutamyltransferase (p=0.001), glycemia (p=0.003), homeostasis model assessment of insulin resistance (p=0.017), total cholesterol (p=0.014), and triacylglycerols (p=0.008), whereas the control group did not present changes. After intervention, the small intestinal bacterial overgrowth frequency was 30% in the DIET group and 45% in the control group (p=0.327). In the DIET group, an increase in the density of total microorganisms (3.76 ± 7.17 x 10 8 cells g -1 ; p=0.048) was detected, while in the control group reduced Bacteroidetes (-0.77 ± 2.01 x 10 8 cells g -1 , p=0.044) and Verrucomicrobiales (-0.46 ± 0.75 x 10 8 cells g -1 ; p=0.022) were observed.

Conclusions: The results suggest that exclusively dietary modifications contribute to health promotion in non-alcoholic steatohepatitis and should be the basis of nutritional treatment for this condition.
