Authors: Abadjieva Emilia , Abadjiev Valentin
Published: August 2017

This work is developed on the basis of the illustrated main parts of the kinematic theory (theory of gearing) of the spatial rack drives in Part 1 of this study. The applied theoretical approach to their synthesis, based on the T. Olivier’s second principle is defined. A study of the geometric nature of the surface of action (mesh region, respectively) of these class transmissions is shown. Research software programs for synthesis and visualization of these transmissions and their specific elements are elaborated, on the basis of the given algorithms to the synthesis of the elements of high kinematic joints (active tooth surfaces), with which the movable links of the studied gear systems are equipped.
Failure Mechanisms of Brittle Rocks under Uniaxial Compression
Authors: Liu Taoying , Cao Ping
Published: August 2017

The behaviour of a rock mass is determined not only by the properties of the rock matrix, but mostly by the presence and properties of discontinuities or fractures within the mass. The compression test on rock-like specimens with two prefabricated transfixion fissures, made by pulling out the embedded metal inserts in the pre-cured period was carried out on the servo control uniaxial loading tester. The influence of the geometry of pre-existing cracks on the cracking processes was analysed with reference to the experimental observation of crack initiation and propagation from pre-existing flaws. Based on the rock fracture mechanics and the stress-strain curves, the evolution failure mechanism of the fissure body was also analyzed on the basis of exploring the law of the compression-shear crack initiation, wing crack growth and rock bridge connection. Meanwhile, damage fracture mechanical models of a compression-shear rock mass are established when the rock bridge axial transfixion failure, tension-shear combined failure, or wing crack shear connection failure occurs on the specimen under axial compression. This research was of significance in studying the failure mechanism of fractured rock mass.
Interest rate pass-through: a nonlinear vector error-correction approach
Authors: Popiel Michal Ksawery
Published: August 2017

This paper analyzes pass-through from money market rates to consumer retail loan and deposit rates in Canada from 1983 to 2015 using a nonlinear vector error-correction model. This model permits estimation of long-run pass-through coefficients while simultaneously accounting for asymmetric adjustments and short-run dynamics. In contrast to empirical frameworks used in previous studies, it also allows testing of commonly made assumptions such as exogeneity of the market rate, making inference more robust. I find that pass-through was complete for all rates before the financial crisis although only after the mid 1990s for the 1 year mortgage rate. Since the end of the 2008–2009 recession, pass-through remains complete in the mortgage market but has significantly declined for deposit rates. Furthermore, many rates adjust asymmetrically but the direction of rigidity differs among rates and time periods.
SETinSTONE: an impact assessment of the human and environmental resource requirements of Late Bronze Age Mycenaean monumental architecture
Authors: Brysbaert Ann
Published: August 2017

Mycenaean monumental architecture has been well studied. Yet the extent to which large-scale building programmes may have contributed to change and crises in Late Bronze Age Greece (c. 1600–1100/1070 BC) has never been investigated using actual field data. The aim of the SETinSTONE project is to assess if and how monumental building activities in Late Bronze Age Greece affected the political and socio-economic structures of Mycenaean polities, and how people may have responded to these changes (Brysbaert 2013).
Neolithic developments in the Gorgan Plain, south-east of the Caspian Sea
Authors: Roustaei Kourosh , Nokandeh Jebrael
Published: August 2017

Until about two decades ago, the Neolithic of north-east Iran was known only from a few brief excavation reports: the sites of Yarim Tappeh (Stronach 1972) and Turang Tappeh (Deshayes 1967) on the Gorgan Plain, and preliminary reports of large-scale excavations at the twin mound of Sang-e Chakhmaq in the southern foothills of the eastern Alborz Mountains (e.g. Masuda 1984). In the absence of absolute chronologies, these sites were dated by ceramic assemblages to the sixth millennium BC, and were considered to relate to the so-called ‘Jeitun Culture’ of southern Turkmenistan (Figure 1; Roustaei 2016a).

Published: August 2017

THE SINGLE-LEG GLUTE BRIDGE IS A VARIATION OF THE BARBELL HIP THRUST THAT INVOLVES UNILATERAL HIP EXTENSION. GLUTE BRIDGE EXERCISES ARE USED AS A MEANS OF STRENGTHENING THE HIP EXTENSORS: THE GLUTEAL AND HAMSTRING MUSCLE GROUPS. IN ADDITION TO ACTIVATING THE POSTERIOR MUSCULATURE OF THE HIP, SINGLE-LEG GLUTE BRIDGES REQUIRE STABILIZATION OF BOTH THE HIP ABDUCTORS AND CORE MUSCLES THROUGH ISOMETRIC CONTRACTION. BECAUSE STRONG GLUTEAL AND HAMSTRING MUSCLE GROUPS ARE IMPERATIVE IN LATERAL STABILIZATION AND EXPLOSIVE LINEAR MOVEMENT, THE SINGLE-LEG GLUTE BRIDGE IS BENEFICIAL TO THE GENERAL POPULATION AND ATHLETES IN A VARIETY OF SPORTS, SUCH AS SOCCER, FOOTBALL, AND RUGBY.
Antioxidant Treatment in Male Mice Prevents Mitochondrial and Synaptic Changes in an NMDA Receptor Dysfunction Model of Schizophrenia

Published: August 2017

Glutamate theories of schizophrenia suggest that the disease is associated with a loss of NMDA receptors, specifically on GABAergic parvalbumin-expressing interneurons (PVIs), leading to changes in the excitation–inhibition balance in the prefrontal cortex (PFC). Oxidative stress contributes to the loss of PVI and the development of schizophrenia. Here, we investigated whether the glutathione precursorN-acetyl cysteine (NAC) can prevent changes in synaptic transmission at pyramidal cells and PVIs that result from developmental NMDAR blockade and how these changes are related to mitochondrial dysfunction in the PFCs of mice. Perinatal treatment with ketamine induced persistent changes in the reduced glutathione/oxidized glutathione (glutathione disulfide) ratio in the medial PFC, indicating long-lasting increases in oxidative stress. Perinatal ketamine treatment also reduced parvalbumin expression, and it induced a decline in mitochondrial membrane potential, as well as elevations in mitochondrial superoxide levels. At the level of synaptic function ketamine reduced inhibition onto layer 2/3 pyramidal cells and increased excitatory drive onto PVI, indicating long-lasting disruptions in the excitation–inhibition balance. These changes were accompanied by layer-specific alterations in NMDAR function in PVIs. All of these changes were mitigated by coadministration of NAC. In addition, NAC given only during late adolescence was also able to restore normal mitochondria function and inhibition at pyramidal cells. These results show that ketamine-induced alterations in PFC physiology correlate with cell type-specific changes in mitochondria function. The ability of NAC to prevent or restore these changes supports the usefulness of antioxidant supplementation in the treatment of schizophrenia.

Published: August 2017

Cocaine exposure alters gene expression in the brain via methylation and acetylation of histones along with methylation of DNA. Recently, poly (ADP-ribose) polymerase-1 (PARP-1) catalyzed PARylation has been reported as an important regulator of cocaine-mediated gene expression. In this study, we report that the cellular microRNA “miR-125b” plays a key role for cocaine-induced PARP-1 expression. Acute and chronic cocaine exposure resulted in the downregulation of miR-125b concurrent with upregulation of PARP-1 in dopaminergic neuronal cells and nucleus accumbens (NAc) of mice but not in the medial prefrontal cortex (PFC) or ventral tegmental area (VTA).In silicoanalysis predicted a binding site of miR-125b in a conserved 3’-untranslated region (3’UTR) of the PARP-1 mRNA. Knockdown and overexpression studies showed that miR-125b levels negatively correlate with PARP-1 protein expression. Luciferase reporter assay using a vector containing the 3’UTR of PARP-1 mRNA confirmed regulation of PARP-1 by miR-125b. Specific nucleotide mutations within the binding site abrogated miR-125b’s regulatory effect on PARP-1 3’UTR. Finally, we established that downregulation of miR-125b and concurrent upregulation of PARP-1 is dependent on binding of cocaine to the dopamine transporter (DAT). Collectively, these results identify miR-125b as a post-transcriptional regulator of PARP-1 expression and establish a novel mechanism underlying the molecular effects of cocaine action.
Using Iterative Group Presentations in an Introductory Biology Course to Enhance Student Engagement and Critical Thinking
Authors: Aguilera Anna , Schreier Jesse , Saitow Cassandra
Published: August 2017

In this study, we examined two types of group presentation assignments for use in a large, introductory biology course. Students were placed into groups of 6 to 8 members, and tasked with researching a topic and preparing a 10-minute in-class presentation. The assignments varied by course section; in the control section, each group's topics were selected to complement the course topic, whereas in the iterative sections, each group's topic would derive from the previous group's presentation. Students’ critical thinking skills were assessed before and after the semester's presentations, and exit surveys were conducted. Results show that students in the iterative group performed better than control on exam questions, and overall interest in biology was high in both groups as a result of the presentations. Overall, performing group presentations in an iterative style enhanced learning by mimicking the scientific process of inquiry and discovery.

Published: August 2017

National STEM education reform efforts call for increased emphasis on science practices, such as modeling. We describe an activity where students read a scientific blog post relating human gametogenesis to disease and then during class develop a model explaining why defects in meiotic machinery cause this disease. This interactive activity was implemented in two sections of an introductory biology course, each exceeding 150 students. Overall, students responded positively to the activity, and based on follow-up exam questions addressing the main learning goals of the modeling activity, about 70 percent of students mastered the learning objectives associated with the modeling activity.
Kyoto Cuisine Gone Global
Authors: de St. Maurice Greg
Published: August 2017

In the face of globalization, chefs in Kyoto, Japan have worked to protect local food culture and revive the local food economy. Their actions do not constitute “resistance,” nor are they simply signs of the persistence of local difference in the context of large-scale changes. Drawing primarily on interviews I conducted with prominent chefs of “traditional” Kyoto cuisine and participant observation at events related to Kyoto cuisine, this article examines chefs’ approaches to outside influence and promotion efforts abroad. I pay specific attention to the incorporation of new foreign ingredients into Kyoto cuisine and new efforts to share culinary knowledge with foreign chefs, namely the establishment of a work visa system and the creation of a cookbook series targeted at professional chefs abroad. Kyoto's chefs, this article demonstrates, have been strategically engaging with globalization, actively refashioning the local to try to control it at a global scale.
Let Them Eat Royal Court Cuisine! Heritage Politics of Defining Global Hansik
Authors: Kim Chi-Hoon
Published: August 2017

The recent race among nation-states to promote national cuisine as a way to counter globalization has marked food as a resource to reinforce national identity and preserve local food heritage. In 2008, South Korean president Lee Myung-bak joined this “food war” by launching the Global Hansik Campaign to reinforce Korean national identity and enhance the nation's image. The government chose royal court cuisine of the Joseon dynasty (1392–1910) as the national representative to present a unified and culturally refined image to simultaneously neutralize local differences and project its global desires. Yet, rather than providing a unifying front for Koreans to project nationalism, the selection of court cuisine fomented debates among local, national, and international actors about what constitutes culinary heritage. Exploring how the state navigated domestic, regional, and global power relations demonstrates that debates surrounding heritage remain tethered to global forces that reproduce the hegemonic social order.
China's Emerging Food Media: Promoting Culinary Heritage in the Global Age
Authors: Kuang Lanlan
Published: August 2017

In light of increasing media attention and commercial interest in documenting Chinese cuisine, this article examines the presentation of food in today's mainstream Chinese media and the effects of its aesthetics in China and around the globe. Identified herein are the various stages of what I call a mediated discursive transformation of China's foodscape and culinary heritage in the globalization era, which started with an upsurge of gastronomic writing in China's print media and is being furthered by a generation of globally conscious Chinese elites. To examine the mediated process of Chinese cuisine under the influence of globalization and, particularly, the impact that the transforming Chinese food media may have on its local and indigenous foodscape, I conducted ethnographic fieldwork on the local, humanistic street food culture of Chongqing and the indigenous, halal cuisines of Lanzhou Muslim, and carried out a content analysis of the new Chinese food documentaries against a background of lively, sometimes heated, and growingly sophisticated arguments of Chinese viewers-turned-bloggers over the aesthetic choices made in these films.
Modulating NAD+ metabolism, from bench to bedside
Authors: Katsyuba Elena , Auwerx Johan
Published: August 2017

Discovered in the beginning of the 20th century, nicotinamide adenine dinucleotide (NAD+) has evolved from a simple oxidoreductase cofactor to being an essential cosubstrate for a wide range of regulatory proteins that include the sirtuin family of NAD+‐dependent protein deacylases, widely recognized regulators of metabolic function and longevity. Altered NAD+ metabolism is associated with aging and many pathological conditions, such as metabolic diseases and disorders of the muscular and neuronal systems. Conversely, increased NAD+ levels have shown to be beneficial in a broad spectrum of diseases. Here, we review the fundamental aspects of NAD+ biochemistry and metabolism and discuss how boosting NAD+ content can help ameliorate mitochondrial homeostasis and as such improve healthspan and lifespan.

Published: August 2017

Objective

To examine the anthropometric, and metabolic connections of 17-hydroxypregnenolone in the normo- and hyperandrogenemic polycystic ovary syndrome phenotypes.

Materials and methods

This cohort study was conducted at the Julio Muller University Hospital, Cuiabá, Brazil, between January 2014 and July 2016, and 91 normal cycling healthy women, 46 normoandrogenemic and 147 hyperandrogenemic, patients with polycystic ovary syndrome (PCOS) were enrolled according to the Rotterdam criteria. Several anthropometric, biochemical and hormonal parameters were properly verified and correlated with 17-hydroxypregnenolone (17-OHPE) concentrations.

Results

17-OHPE was higher in hyperandrogenemic PCOS than in normoandrogenemic PCOS and in control groups (P = 0.032 and P < 0.001, respectively). In healthy controls, 17-OHPE was positively associated with glucose, free estrogen index, DHEAS and negatively associated with compounds S. In normoandrogenemic PCOS patients, 17-OHPE presented positive correlations with VAI, LAP, cortisol, insulin and HOMA-IR. In the hyperandrogenemic group, 17-OHPE presented significant negative correlations with most anthropometric parameters, HOMA-IR, HOMA %B, estradiol, free estrogen index (FEI), C-peptide, and TG levels and positive correlations with HOMA-S and high-density lipoprotein cholesterol (HDL-C), sex-hormone binding globulin (SHBG), androstenedione (A4) and dehydroepiandrosterone (DHEA). Regarding hyperandrogenemic PCOS, and using a stepwise multiple regression, only HOMA-S and WHR were retained in the model (R2 = 0.294, P < 0.001).

Conclusion

17-OHPE exhibited different relationships with anthropometric, and biochemical parameters in PCOS patients, depending on the androgen levels. In PCOS subjects with high androgen concentrations, 17-OHPE was negatively associated with most anthropometric parameters, particularly with those used as markers of adipose tissue dysfunction and frequently employed as predictors of cardiovascular disease risk; otherwise, 17-OHPE was positively associated with HDL-C and HOMA-S in this patients. Future studies are required to evaluate the clinical implications of these novel findings.

Evaluation of Quetiapine Fumarate and its Solid Lipid Nanoparticles as antipsychotic drug in rat model of schizophrenia
Authors: M. Said M. , Elmenoufy Gehan A.
Published: August 2017

Background: The present study compares the efficacy of quetiapine fumarate (QF) and QF-loaded solid lipid nanoparticles (QFSLN) as antipsychotic drugs for schizophrenia. Methods: To induce schizophrenia-like symptoms, a group of rats was injected intraperitoneally (i.p.) with ketamine (25mg/kg b.w.) for 1 week to establish a rat model of schizophrenia. The incidence of schizophrenic symptoms was estimated to be equivalent to the control group. To estimate the pronounced antipsychotic effect of QF, a low dose (LD) of 10 mg/kg b.w. and a high dose (HD) of 30 mg /kg b.w. were orally administrated to two groups of rats (designated L.QF and H.QF) for 3 weeks (2 weeks without ketamine injection; the last week with ketamine). To achieve the optimal therapeutic response of QF drug, 2 other groups of rats were administered orally the equivalent low and high doses of QF in its solid lipid nanoparticle form (L.QFSLN) and (H.QFSLN) for 3 weeks in the same manner. The treatments were given after 1 h of ketamine injection. To assess the effect of different doses of treatment on hyperlocomotion and cognitive impairment induced by ketamine, an open field test and passive avoidance test were conducted. In addition, excitatory and inhibitory amino acids, as well as catecholamines, were estimated in brain regions (cortex and hippocampus). The study was extended to estimate the side effects of different treatments on hepatorenal functions and lipid profile. Additionally, samples were subjected to immunohistochemical analysis. Results: QFSLN treatment showed enhanced effect over QF in a dose-dependent manner with minimal side effects in schizophrenic rats. In addition, immunohistochemical examinations of brain tissues confirmed the biochemical data.

Ecology + Anthropology = Ecological Anthropology?
Authors: Borsos Balázs
Published: August 2017

An attempt is made to summarize the emergence and evolution of a sub-territory in anthropology, namely ecological anthropology. First the name of this discipline is considered, that deals with the interrelationship of culture and nature from cultural ecology to human ecology concluding to ecological anthropology. Here the word ecology appears in an attributive compound suggesting that it is a field of anthropology using ecological concepts as well. The second part of the article provides a brief history of the discipline from the beginnings (determinism, possibilism) through the emergence of the cultural ecology theory by Julian H. Steward and the work of neo-evolutionists (White, Sahlins, Harris), to the most ‘ecological’ investigations of the neo-functionalists (Vayda, Rappaport, Moran) who introduced the use of the category ecosystem in their research. The latter concept is analysed a bit more in details, mainly with the work of Roy Rappaport in the focus. The third part presents the different approaches of the last 30 years, ranging from environmental history up to radical ecology. It emphasizes the importance of ethno-science and cognitive anthropology, which appear in ecological anthropology in the fifties (Conklin) and flourish up today. Finally the process of ‘sacralisation’ of the research in ecological anthropology is outlined, namely the emergence of spiritual ecology and the investigation of traditional ecological knowledge which can help in resources management of the modern world just as well.
Post Industrialist Pioneers. Gyűrűfű: An Ecological Anthropological Experiment
Authors: Borsos Béla
Published: August 2017

Gyűrűfű, a small village in Zselic, South-Transdanubia depopulated in the 1970s, is the site of an eco-village experiment since 1990. In addition to some of the physical aspects of the project not covered earlier on, this paper deals with the human ecological features of the new community. Social-anthropological considerations such as community development, social background of the participants, the Communist past, which all are determining factors of the social model emerging on site, are discussed from the systems theoretical perspective which states that certain properties of a subsystem are always defined by the superimposed supersystem, both in physical geography and social organisation. The resulting tensions stretched social cohesion in the past 10–15 years, but new developments such as creating jobs by modern telecommunication means and achieving energy independence through the deployment of solar panels and passive energy conservation solutions off-set for these difficulties. The future of the experiment depends very much on three factors: generation change, immigration/emigration and conflict resolution.

ABSTRACT Objective: To assess the development and implementation of permanent education action. Method: Quantitative-qualitative research based on action research in three phases (diagnosis of reality, implementation of activity and evaluation), performed with health professionals and managers of basic health units. The evaluation was on the perception of changes immediately following the activity and after 120 days. Results: In the first phase, 110 professionals took part, 36.4% of whom indicated the existence of groups for older adults at work. In the second phase, 98 professionals participated, pointing out interferences of the group in the life of older adults, items of importance and facilitation in forming groups and developing reality-based activities. The third phase showed, in the quantitative analysis, positive impact of the training, and in the qualitative analysis, reassessment of groups, greater knowledge and confidence in managing groups and increased respect for older adults. Final considerations: Permanent education opens pathways for the construction of differentiated care for older adults based on respect and health promotion.

ABSTRACT Objective: to evaluate the relation between stress and optimism of elderlies who are informal caregivers for elderlies and live with children. Method: cross-sectional study on 50 elderlies who provide care to elderlies, live with children, and are registered in the primary health care. The interviews occurred in the participant's residence and we evaluated characteristics of the care-dependent elderly and of the children, sociodemographic characteristics, stress through the Perceived Stress Scale and optimism through the Pinto and Pais-Ribeiro Spirituality Scale, in the elderly caregiver. For statistical analysis we used the Spearman correlation test. Results: the mean level of stress was 23.9 points and of optimism was 3.3 points. Correlation analysis showed that the higher the level of optimism the significantly lower the level of perceived stress of elderlies who provided care to elderlies and lived with children. Conclusion: inversely proportional correlation was identified between stress and optimism.

ABSTRACT Objective: to identify the social representations of older adults regarding quality of life, and to analyze the care practices adopted to promote it. Method: qualitative, exploratory, descriptive research, applying the Theory of Social Representations. Thirty older people from a Health Academy of Rio de Janeiro participated in the study. The software Alceste was used, and lexical analysis of data was performed. Results: social representations of quality of life are based on the social determinants of health; they evidence knowledge and practices of care by valuing physical activities. The practices promoting quality of life comprise healthy eating habits, daily physical exercise, social participation, interaction and socialization, accomplishment of leisure activities and daily tasks with independence and autonomy, and support and family contact. Final considerations: the elderly have a global understanding of the concept of quality of life, coordinate knowledge built in daily life and knowledge coming from the technical-professional field, which evidences the multidimensionality of the concept.

ABSTRACT Objective: To describe the quality of life (QOL) of elderly people with Chronic Kidney Disease (CKD) in conservative treatment, correlating it with sociodemographic and health-related aspects. Method: This is a quantitative, cross-sectional, and descriptive study that used: a previously validated instrument for data collection; the WHOQOL-BREF and WHOQOL-OLD QOL scales; and the Mini-Mental State Examination. Results: Thirty-five elderly people (54.30% females), with mean age of 68.26 years, took part in the study. They reported, on average, 3.70 comorbidities and 5.60 complications related to CKD. Regarding QOL, the "psychological" domain (54.40±16.29) and the "death and dying" facet (37.32±23.79) were considered the most damaged ones; the most strengthened were "social relationships" (70.36±18.32) and "intimacy" (66.61±16.80). A positive correlation was verified between comorbidities and complications (p = 0.015), and an inverse correlation between the number of complications and QOL (p = 0.004). Conclusion: These results, if considered during the care planning, may help improving the quality of the care provided for elderly people with CKD.

ABSTRACT This study evaluated the use of cashew fiber in combination with textured soybean protein for the preparation of vegetable burger. Two treatments were studied to reduce fiber size (mechanical pressing with or without enzymatic maceration) and its impact on physical chemical characteristics, sensory acceptance and stability of burgers stored at -18 °C for 180 days. Both burger formulations had high moisture and carbohydrate contents and low lipid contents. Enzymatic fiber maceration resulted in harder products with lower moisture content. During storage, reduction in pH and ascorbic acid and increase in acidity values were observed, with no tendencies for color values. Throughout the storage period, burgers were within microbiological standards of the Brazilian legislation for human consumption and average sensory acceptance was within acceptance zone. It was concluded that the inclusion of enzymatic maceration in the fiber treatment process has no advantages and that burgers elaborated with cashew fiber and textured soybean protein can be consumed up to six months of frozen storage.
