Three-dimensional real-space crystallography of MCM-48 mesoporous silica revealed by scanning transmission electron tomography

Yates, Timothy J.V.,Thomas, John Meurig,Fernandez, Jose-Jesus,Terasaki, Osamu,Ryoo, Ryong,Midgley, Paul A. Elsevier 2006 Chemical physics letters Vol.418 No.4

<P><B>Abstract</B></P><P>High-angle annular dark-field scanning transmission electron tomography has been used to reveal the three-dimensional lattice structure of the mesoporous silica MCM-48. The incoherent nature of the dark-field signal leads to directly interpretable images and three-dimensional tomographic reconstructions. The ability to manipulate the three-dimensional reconstruction allows the structure to be visualised at any orientation, revealing detail in projection or as slices not hitherto seen by direct imaging techniques.</P>

Elevated folic acid results in contrasting cancer cell line growth with implications for mandatory folic acid fortification

Yates, Zoe,Lucock, Mark,Veysey, Martin,Choi, Jeong-hwa 한국영양학회 2016 Journal of Nutrition and Health Vol.49 No.2

Purpose: The initiation of mandatory folic acid fortification using pteroylmonoglutamic acid (PteGlu) has reduced the rate of congenital malformations. However, it also appears to be responsible for several adverse effects, including increased cancer incidence. This may be related to physicho-chemical characteristics of PteGlu. This study examines the potential effect of high concentrations of PteGlu on a population subjected to mandatory folic acid fortification using an in vitro model. Methods: Caco-2 (colorectal cancer) and MCF7 (breast cancer) cell lines were cultured at 6 different PteGlu concentrations (0, 0.1, 1, 50, 250, and 500μg/ml) for 6 days. Cell growth was determined using thiazolyl blue tetrazolium bromide assay. The genotype of dihydrofolate reductase 19bp deletion/insertion (DHFR 19-del) was also scored in cell lines using a restriction fragment length polymorphism technique to examine whether genetic variations may factor in cell proliferation. Results: PteGlu exhibited differential growth promoting properties between cell lines. Caco-2 cells did not show a significant growth difference at low concentrations compared to control, however, at higher concentrations, the growth showed a contrasting trend in the early experimental period, while MCF7 showed enhanced cell growth at all concentrations. The DHFR 19-del genotype differed in the two cell lines. Conclusions: Altered response to PteGlu by Caco-2 and MCF7 may reflect a tissue specific disease aetiology or genotype specific differential enzyme activity, for example by DHFR, to critical levels of PteGlu. As folic acid fortification is a blanket intervention, and DHFR and other enzyme activities vary between individuals, PteGlu intake may have an as yet undefined effect on health. These findings may be relevant when considering mandatory folic acid fortification for disease prevention.

Aligning tradition and creativity: preserving pansori in South Korea

Anna Yates-Lu 국립민속박물관 2019 International Journal of Intangible Heritage Vol.14 No.-

In 2016, the South Korean government implemented theAct on the Safeguarding and Promotion of IntangibleCultural Properties (Muhyeong munhwajae bojeon mitjinheung e gwanhan beomnyul), thus entering a newstage in the preservation of intangible cultural heritage. Through tracing the development of the preservation ofpansori, a sung storytelling art form which was amongstthe first to be designated as intangible cultural heritagein Korea in 1964, I discuss how patterns of preservationstrategies have emerged, as well as how these are beingtargeted by the new legislation. Although it is still tooearly to observe the lasting effects of the new legislation,an analysis of the critiques of the previous system, as wellas the hopes pinned on the future, will indicate potentialfuture trends.

Ethnomusicology in Practice : Learning and Performing Pansori as a Research Tool

Anna Yates Lu 한국예술종합학교 무용원 2021 무용과 이론 Vol.3 No.-

It is widely accepted in contemporary Western* 9) ethnomusicological scholarship that, as part of fieldwork, researchers will themselves learn the genres they are studying, often not just to the level of ‘bi-musicality’ (Hood 1960) but to the level of professional performance (Baily 2001). In contrast, Korean musical scholarship, while especially strong in musicological analysis and historical musicology, has only received limited impact from Western traditions of ethnomusicological research (Park Mikyung 2013: 25). In examining the different scholarly traditions encountered in my research on Korean sung storytelling form pansori, I postulate that it is through the practical learning and performance of a musical genre that the gap between different research approaches can be breached. By showing demonstrable skill and in-depth knowledge of a genre in terms acceptable to local music scholars, an ‘outsider’ scholar can build a path to engage with and thus build bridges between academic traditions that have so far mostly developed independently, fostering the potential for constructive future debate.

Oil and Conflict in the Pacific

Douglas A. Yates 세계환경사회거버넌스학회 2015 World Environment and Island Studies Vol.5 No.3

Oil and conflict are dangerously intertwined in the Pacific, where China has several disputes with its neighbors. The Senkaku (Diaoyu) islands in the Ryuku chain of the East China Sea which are reported to possess large oil reserves offshore are currently disputed by China and Japan. The Paracel (Xisha) islands of the South China Sea, also rich in oil reserves, have caused low intensity conflict between China and Vietnam. And once oil was discovered the Spratley islands, in the South China Sea north of Brunei, are disputed by five countries: Indonesia, Brunei, Philippines, Malaysia and China, whose large blue water navy and military installations are enforcing what it claims to be its exclusive sphere of influence. Meanwhile in the Straits of Malacca the Chinese navy has sent a flotilla to accompany the long column of oil tankers which carry most of the oil imports of East Asia. Oil has caused a veritable 'petro pirate plague' in the straits between Malaysia, Singapore and Indonesia, threating East Asia's vital supply of crude oil. All of these new conflicts offshore raise questions of regional security in the Asia-Pacific region. Is the oil these islands are reported to possess worth an interstate war? China should instead work with its neighbors to make the East and South China seas safe for commerce.

Establishing new principles for nutrient reference values (NRVs) for food labeling purposes

Allison A. Yates 한국영양학회 2007 Nutrition Research and Practice Vol.1 No.2

Many countries such as The Republic of Korea have established their own nutritional standards, collectively termed Nutrient Reference Values (NRVs), and they vary due to the science which was reviewed, the purposes for which they are developed, and issues related to nutrition and food policy in the country. The current effort by the Codex Alimentarius Committee on Nutrition and Foods for Special Dietary Uses (CNFSDU) to update the NRVs that were established following the Helsinki Consultation in 1988 represents an opportunity to develop a set of reference values reflecting current scientific information to be used or adapted by many countries. This paper will focus on possible approaches to selecting or developing reference values which would serve the intended purpose for nutrition labeling to the greatest extent possible. Within the United States, the Food and Drug Administration (U.S. FDA) is currently reviewing regulations on nutrition labeling to better address current health issues, and is expected to enter into a process in the next few months to begin to explore how best to update nutrient Daily Values (DVs), most of which are still based on the Recommended Dietary Allowances (RDAs) of the Food and Nutrition Board, U.S. National Academy of Sciences, last reviewed and revised in 1968. In this presentation, I review the current purposes in the U.S. for nutrition labeling as identified in the 1938 Food, Drug, and Cosmetic Act as amended, the scientific basis for current nutrition labeling regulations in the United States, and the recommendations made by the recent Committee on Use of Dietary Reference Intakes in Nutrition Labeling of the Institute of Medicine (2003) regarding how to use the DRIs in developing new DVs to be used on the label in the United States and Canada. Based on these reviews, I then provide examples of the issues that arise in comparing one approach to another. Much of the discussion focuses on the appropriate role of nutrient labeling within the Nutrition Facts panel, one of the three major public nutrition education tools in the United States (along with MyPyramid and Dietary Guidelines for Americans).
