Effects of Tocols Rich Fraction Isolated from Rice Bran Oil Deodorizer Distillate on Plasma and Hepatic Lipid Concentrations in Rats  [PDF]
Tina A. Gomes, Xuan Gu, Cindi R. Brownmiller, Luke Howard, Cesar M. Compadre, Sun-Ok Lee
Journal of Biosciences and Medicines (JBM) , 2015, DOI: 10.4236/jbm.2015.39001
Abstract: A great deal of attention has been focused on the potential health benefits of using rice bran oil because it is a rich source of bioactive compounds. Rice bran oil deodorizer distillate (RBODD) is a byproduct obtained from distillation of rice bran oil. Elevated plasma cholesterol level is one of the major risk factors for coronary heart disease. The objective of this study was to investigate the effects of tocols (tocopherols + tocotrienols) rich fraction isolated from RBODD on plasma and liver lipid concentrations in rats. Male Sprague Dawley rats (6 weeks of age) were randomly assigned into three groups: normal fat control (NFC), high fat control (HFC) and high fat diet plus tocols rich fraction (RBODD). RBODD was administered daily for 3 weeks by oral gavage using 5% of Tween-80 as a vehicle. The rats in the control groups received 5% of Tween-80 alone in the same manner. Blood samples and livers were collected at the end of the feeding period. RBODD group had significantly lower plasma triglyceride levels compared to the HFC group (p < 0.05). However, no significant changes for plasma total and lipoprotein cholesterol levels were found in RBODD compared with HFC. Compared to the rat fed HFC, hepatic free fatty acids were significantly reduced in the rats with the RBODD treatment (p < 0.05). The results suggest that the tocols rich fraction isolated from RBODD is associated with decreased plasma triglyceride and hepatic free fatty acids concentrations. Further study is needed to investigate the mechanism and optimal dose by which isomers of tocols lower triglyceride concentrations.
Cosmetic Surgery as Intrasexual Competition: The Mediating Role of Social Comparison  [PDF]
Steven Arnocky, Tina Piché
Psychology (PSYCH) , 2014, DOI: 10.4236/psych.2014.510132
Abstract:

Cosmetic surgical procedures have previously been associated with some risks to psychological and physical health. Yet such procedures are on the rise, highlighting the need for a better understanding of the factors which might underlie the decision to undergo cosmetic surgery. In a sample of 297 young adults (192 women), we examined the relationship between intrasexual competition (IC), social comparison, and individuals’ attitudes, perceived risks, and desired spending on cosmetic surgical procedures. Results showed that women perceived more risk to cosmetic surgery, yet held more positive attitudes and desire to spend on cosmetic surgery compared to men. For both men and women, IC predicted positive attitudes and desired spending on cosmetic surgery. Social comparison mediated all relationships between IC and cosmetic surgery variables. Cosmetic surgery is discussed as a potential form of intrasexual competition rooted in the mate-preferences of the opposite sex.

Comparative Analysis of Cartographic Literacy in the Selected Curricula at the Primary Level  [PDF]
Vlasta Hus, Tina Hojnik
Creative Education (CE) , 2013, DOI: 10.4236/ce.2013.412107
Abstract: Basic knowledge of maps, because of its widespread use, has become a part of the individual’s modern literacy. This is why we were interested in how this kind of literacy is represented in schools, when it occurs and how it is upgraded. Based on the study of literature we have formed criteria of cartographic literacy and based on the comparative method we have compared curricula for the lower stage of primary education of two countries (England and Slovenia). We found that cartographic literacy is given most attention, as well as in content as in didactic recommendations, in the Slovene curriculum for Social Studies (second triad). But according to the pupils’ cognitive abilities, it is being introduced too late. In the English curriculum for Geography initial cartography is far more dependent on the teachers and their cartography knowledge (or lack of it) because of the general definition of objectives and lack of recommendations. A combination of such an open curriculum and teacher’s cartography knowledge (or lack of it) can push cartographic literacy a step back from other content. That is why educating teachers and paying attention to the matter either in the curriculum or in textbook sets is of utmost importance.
Cognitive Behavior Therapy of Urinary Incontinence Phobia: A Case Report  [PDF]
Tina Tan, Leslie Lim
Open Journal of Psychiatry (OJPsych) , 2015, DOI: 10.4236/ojpsych.2015.51009
Abstract: A significant association exists between lower urinary tract symptoms and anxiety. Despite the efficacy of cognitive behavior therapies in treating a variety of phobic disorders, there are few published reports about the use of such treatments for urinary problems. We report a case of the phobia of urinary incontinence treated with cognitive behavioral techniques, which involved cognitive restructuring, distraction, relaxation training, and exposure to feared situations.
Mitochondria and PGC-1α in Aging and Age-Associated Diseases
Tina Wenz
Journal of Aging Research , 2011, DOI: 10.4061/2011/810619
Abstract: Aging is the most significant risk factor for a range of degenerative disease such as cardiovascular, neurodegenerative and metabolic disorders. While the cause of aging and its associated diseases is multifactorial, mitochondrial dysfunction has been implicated in the aging process and the onset and progression of age-associated disorders. Recent studies indicate that maintenance of mitochondrial function is beneficial in the prevention or delay of age-associated diseases. A central molecule seems to be the peroxisome proliferator-activated receptor γ coactivator α (PGC-1α), which is the key regulator of mitochondrial biogenesis. Besides regulating mitochondrial function, PGC-1α targets several other cellular processes and thereby influences cell fate on multiple levels. This paper discusses how mitochondrial function and PGC-1α are affected in age-associated diseases and how modulation of PGC-1α might offer a therapeutic potential for age-related pathology. 1. Introduction In the last 20 years, mitochondrial dysfunction has been recognized as an important contributor to an array of human pathologies [1–3]. Mitochondrial dysfunction is particularly associated with the onset and progression of many age-related disorders such as neurodegenerative and cardiovascular diseases as well as metabolic disorders and age-related muscle wasting. In most cases it is not clear if the mitochondrial dysfunction is causative of the disease or if it is a secondary effect of the disease. Also, it is not understood if mitochondrial dysfunction is an aggravating factor in disease progression. Recent work suggests that maintenance of mitochondrial function is beneficial in at least some age-related diseases [4]. The peroxisome proliferator-activated receptor (PPAR) γ coactivator α (PGC-1α) integrates regulation of mitochondrial function into the modulation of different, tissue-specific metabolic pathways and thereby links mitochondrial function to important cellular signaling pathways that ultimately control cell survival [5, 6]. The following review discusses how mitochondrial dysfunction is associated with age-related diseases and what impact PGC-1α and its targets have in these diseases and their prevention. 2. Mitochondrial Function, ROS, and Aging 2.1. Mitochondrial Function and OXPHOS Mitochondria play a central role in the cell metabolism: besides being key player in apoptosis, mitochondria house major cellular metabolic pathways. The fatty acid oxidation and citric acid cycle convert nutrients absorbed from ingested food to electron donors to NADH and FADH. These
The Machinery of Life
Tina Toni
Human Genomics , 2010, DOI: 10.1186/1479-7364-4-5-369
Abstract: The book is aimed at non-scientific readers and at researchers from different disciplines who are looking for a quick and entertaining, but scientifically sound, introduction to molecular biology. But even experienced researchers across the biological sciences will derive great pleasure from dipping into the book and its charming hand-coloured pictures. The Machinery of Life is all about putting basic biological knowledge into perspective and developing intuition about how biological molecules assemble to build organelles, cells and whole organisms.The book wonderfully develops the understanding of a multi-scale view on the mechanisms of life; it explains how molecules assemble to form cells and how cells work together to build whole multicellular organisms. Without the need to understand thoroughly every single detail of each individual process and molecule, Goodsell teaches us how different molecules act in concert, and makes us appreciate and understand how processes on a molecular level are responsible for getting old, jumping when playing basketball, catching a cold or feeling hungry.The first three chapters of the book cover a quick introduction to basic molecular biology and the biochemistry of molecules such as DNA, lipids and poly-saccharides. We learn how these biological molecules are employed in cells to build new proteins or obtain energy, how they protect the cells and how cells use them to communicate with the environment.The next two chapters describe and contrast the structure and components of Escherichia coli and human cells. Through these model organisms, the reader is able to appreciate the differences between prokaryotic and eukaryotic cells. Viruses are then added to this collection in Chapter 8, which is an engaging introduction to immunology and covers today's pertinent issues, such as HIV and the avian and swine flu viruses. The book explains why vaccines sometimes work and sometimes do not, and why some infections are deadly while others a
Functional Health Status of the Elderly in Taiwan

Healthy Aging & Clinical Care in the Elderly , 2012, DOI: 10.4137/HACCE.S3620
Abstract: Purpose: The purpose of the study is to understand the functional health status of the elderly in Taiwan by using the Chinese version of Minimum Data Set—Home Care (MDS-HC) as a health assessment measurement. Design and methods: Study participants were randomly recruited from southern Taiwan through a two stage strata (Urban/Rural and County/Township) sampling method. The finalized valid study participants were 402. In-person interviewers (n = 12) for this project were professional nurses who were required to attend three MDS training sessions. The average length of data collection (interviewing) was 40 minutes. Data were assessed for inter-rater reliability. Multi-functional information from the following were gathered from participants for analysis: cognitive patterns; communication/hearing; vision; mood and behavior patterns; social functioning; informal support services; physical functioning; continence; disease diagnoses; health conditions and preventive health measures; nutrition/hydration status; dental status; skin condition; environmental assessment; service utilization; and medication information. Results: 82% of the participants rated themselves as healthy and functional older community residents. Subjectively, they considered themselves having no problem with daily functional activities/independence; however, data show the elderly are in need of the following community services: preventive health (99.8%); psychotropics (94.8%); visual function (59.2%); social function (49.8%); health promotion (36.1%); and reduction of formal services (31.3%). Additionally, the Client Assessment Protocol (CAP) triggers several potential problems. Implications: Findings support that specific services should be made available to community-dwelling older adults in Taiwan in order to promote their health status.
New Aspects of Library Design
Tina Hohmann
Liber Quarterly : The Journal of European Research Libraries , 2006,
Abstract: New planning principles are required to meet the changing needs of the users of the library of the future. The digital revolution has changed the appearance of today’s libraries entirely. The majority of today’s information resources are of a non-physical nature and accessing information is more varied and complex. The traditional role as asset keeper is one of many tasks today. The recently completed examples of Dresden and G ttingen State- and University Library, the Seattle Public Library and the Idea Stores in London, all of them highly popular and frequented, show current trends in library design. What do they offer their visitors? access to information guidance (information skills) possibility for communication working environment inspiring atmosphere Their design is based on the following main principles: Access to the library and its medias should be obvious and easy for everybody. There should be multifarious space for formal and informal communication between customers and staff. The interior should offer an attractive and comfortable environment for both customers and staff. The library building should adequately represent its institutional philosophy and aims. Its building design, structure and appliances should give consideration to sustainability.
Diskurs, Subjekt und Handlungsmacht. Zur Verknüpfung von Diskurs- und Biografieforschung mithilfe des Konzepts der Artikulation Discourse, Subject, and Agency. Linking Discourse Analysis and Biographical Research with the Help of the Concept of Articulation Discourso, sujeto y agencia. Vinculando el análisis del discurso y la investigación biográfica con la ayuda del concepto de articulación

Abstract: W hrend in der Biografieforschung lange Zeit der Einfluss von Diskursen auf biografische Erz hlungen nicht berücksichtigt wurde, wird in Diskursanalysen h ufig die subjektkonstituierende Wirkung von Diskursen vernachl ssigt. In diesem Beitrag soll es daher auf theoretischer Ebene um die Frage gehen, wie Diskurs und Subjekt zusammengedacht werden k nnen. Hierzu soll das Konzept der Artikulation von Stuart HALL vorgestellt werden. Stuart HALL hat sich vor allem ab Beginn der 1990er Jahre mit Fragen der (kulturellen) Identit t auseinandergesetzt und hierbei ein Subjektverst ndnis entwickelt, das es erm glicht, Subjekte nicht nur als Effekte von Diskursen zu verstehen, aber dennoch Diskurse in der Subjektkonzeption zu berücksichtigen. Er wurde im deutschsprachigen Raum bisher sowohl in der Biografie- als auch in der Diskursforschung wenig rezipiert, doch sein Konzept der Artikulation k nnte m glicherweise eine Brücke von der Diskurs- zur Biografieforschung schlagen und auch für empirische Arbeiten anschlussf hig gemacht werden. URN: urn:nbn:de:0114-fqs0902369 For a significant period of time biographical research did not focus on the influence of discourses on biographical narratives. In contrast, discourse analysis often disregarded the subject-constituting impact of discourses. This article deals with the theoretical question of how to work with both: discourse and subject. Therefore, I will introduce Stuart HALL's concept of articulation. Since the early 1990's HALL has been working on questions of (cultural) identity. In this context he developed an understanding of subjects that enables them not only to be seen as effects of discourses, but also allows focusing on discourses in subject conceptions. Neither biographical research nor discourse analysis In German speaking countries have embraced the work of HALL. But his concept of articulation could link biographical research and discourse analysis, and could also be used for further empirical work. URN: urn:nbn:de:0114-fqs0902369 En la investigación biográfica no se abordó, durante un período considerable, la influencia de los discursos sobre las narrativas biográficas. En contraste, el análisis de discurso ignoró frecuentemente el impacto de los discursos en el sujeto constituyente. Este artículo aborda la pregunta teórica acerca de cómo trabajar con ambos: discurso y sujeto. Por consiguiente, introduciré el concepto de articulación de Stuart HALL. Desde los tempranos 1990's HALL ha estado trabajando sobre cuestiones de identidad (cultural). En este contexto, HALL desarrolló una comprensión de los suje

Abstract: Der Begriff partizipative Forschung wird mittlerweile h ufig zur Kategorisierung eines Typus von Untersuchungen gebraucht, der sich weg von Forschung "über" Menschen hin zur Forschung "mit" Menschen entwickelt hat. Der Artikel besch ftigt sich mit einigen Unklarheiten eines partizipativen Untersuchungsansatzes und mit deren m glichen Einflüssen auf die konkrete Forschungspraxis. Im Mittelpunkt stehen Probleme, die daraus erwachsen, dass partizipative Forschung an die Anforderungen in akademischen R umen angepasst werden muss, die dieser Methodik aber nur wenig Anerkennung gew hren. Es wird gezeigt, wie wichtig es ist, eigene Forschungsr ume zu kreieren, um partizipative Methodendesigns zu realisieren, die einem diskursiven Ansatz entsprechen. Erst dadurch wird es m glich, die Qualit t und die Resultate dieser Methoden sch tzen zu lernen. Das Hauptargument ist, dass eine besondere St rke partizipativer Forschung darin besteht, eine ganze Vielfalt an sozialwissenschaftlichen Forschungsans tzen und zwecken aufzugreifen. Eine Kl rung der gemeinsamen Kennzeichen des partizipativen Paradigmas und die Entwicklung geeigneter Kritikformen k nnten einen Beitrag dafür liefern, dass partizipative Forschung st rker in der Sozialforschung, der Forschungsf rderung und der ffentlichen Verwaltung aufgegriffen wird. Dadurch würde es auch m glich werden, angemessener die besondere Natur und Absicht einer authentischen Beteiligung der Forschungspartner/innen zur Geltung zu bringen. URN: http://nbn-resolving.de/urn:nbn:de:0114-fqs1201187 The term participatory research is now widely used as a way of categorising research that has moved beyond researching "on" to researching "with" participants. This paper draws attention to some confusions that lie behind such categorisation and the potential impact of those confusions on qualitative participatory research in practice. It illuminates some of the negative effects of "fitting in" to spaces devised by other types of research and highlights the importance of forging spaces for presenting participatory research designs that suit a discursive approach and that allow the quality and impact of such research to be recognised. The main contention is that the adoption of a variety of approaches and purposes is part of the strength of participatory research but that to date the paradigm has not been sufficiently articulated. Clarifying the unifying features of the participatory paradigm and shaping appropriate ways for critique could support the embedding of participatory research into research environments, funding schemes and admini
