The aim was to evaluate the influence of dietary Ca-Mg-phytate consumption on the bone characteristics of ovariectomized rats, an animal model for postmenopausal osteoporosis. Twenty ovariectomized female Wistar rats were randomly assigned to two groups fed, respectively, with a non-phytate diet (AIN-76A) or the same diet enriched with 1%phytate (as the calcium magnesium salt, phytin). After 12 weeks of feeding the rats were sacrificed, and both femoral bones and L4 vertebra were removed from each rat. Bone mass, length, width, volume, and mineral density were measured, and the phosphorus, calcium, magnesium, and zinc contents of bones were determined. Deoxypyridinoline (a bone resorption marker)was measured in urine, and osteocalcin (a bone formation marker) was measured in serum. The calcium and phosphorus contents and bone mineral density were significantly higher in both femoral bones and L4 vertebra for phytate-treated rats in comparison to rats in the non-phytate group. Deoxypyridinoline was significantly increased in rats in the non-phytate treatment group. Ca-Mg-phytate consumption reduces bone mineral density loss due to estrogen deficiency. Thus, phytate exhibits effects similar to those of bisphosphonates on bone resorption and may be of use in the primary prevention of osteoporosis if larger studies in humans confirm these findings.

A Survey of the In Vitro Antifungal Activity of Heather (Erica Sp.) Organic Honey

Xesús Feás,María L. Estevinho 한국식품영양과학회 2011 Journal of medicinal food Vol.14 No.10

Monofloral heather (Erica sp.) honey samples (n=89), harvested in Portugal according to European organic beekeeping rules, were analyzed to test their antifungal effect against Candida albicans, Candida krusei, and Cryptococcus neoformans. A synthetic honey solution was also tested to determine antifungal activity attributable to sugars. The specific growth rate (μ) values showed that growth of all the yeasts was reduced in the presence of honey. The honey concentration (% wt/vol) that inhibited 10% of the yeast growth (Xmin) was 13.5% for C. albicans, 20.5% for C. krusei, and 17.1% for C. neoformans. The respective concentrations of heather honey and synthetic honey in the C. krusei culture medium above 60% (wt/vol) that inhibited 90% of the yeast growth (Xmax) and Xmin, respectively, were established, whereas C. albicans and C. neoformans were more resistant because Xmax values were not reached over the range tested (10–60%, wt/vol). Heather honey might be tapped as a natural resource to look for new medicines for the treatment of mycotic infections. Further studies are now required to demonstrate if this antifungal activity has any clinical application.

Francisco Rodrı´guez-Fe´lix,Carmen Lizette Del-Toro-Sa´nchez,Jose´ Agustı´n Tapia-Herna´ndez 한국식품과학회 2020 Food Science and Biotechnology Vol.29 No.5

The objective of this work was propose antisolvent-dialysis as a new, easy, one-step and reproduciblemethod for obtaining white zein micro- and nanoparticlespowder. Firstly, the study by SEM of white zein powderpredicted micro- and nanoparticles with spherical morphologyand average diameters of 243.2 ± 94.5 nm fornanoparticles and 0.74 ± 0.2 lm for microparticles. UV–Vis predicted lower absorbance of 250–500 nm for whitezein powder compared to commercial yellow zein powder. FT-IR showed shifting of the main bands to the right, dueto changes in particle-shaped microstructure that acquireswhite zein powder compared to yellow zein powder. InTGA white zein powder showed a decomposition rangefrom 214 to 400 C, while yellow zein powder from 240 to400 C. Therefore, antisolvent-dialysis is new method toobtain white zein micro- and nanoparticles with potentialapplications such as polymer matrix and white naturalcoloring.

개화기 청국 他者 신화의 구축

정립비(Zheng, Li-fe) 호서사학회 2019 역사와 담론 Vol.0 No.89

1896년에 서재필의 주도로 창간된 『독립신문』은 조선 최초의 민간지로서 백성에게 국내외의 사정을 알렸으며 대외인식도 새롭게 심어주었다. 그 중에 청국에 대한 보도가 여러 칼럼에서 대폭적으로 이루어졌으며, 당시의 조선 백성에게 전과 다른 면모를 가진 청국을 재현하였다고 할 수 있다. 필자가 바로 본고에서 『독립신문』의 ‘논설’란뿐만 아니라 기타 칼럼에서 게재된 청국 관련 기사도 체계적으로 고찰하며, 기사를 텍스트로 간주하여 내용적·서사적 측면에서 분석함으로써 『독립신문』에서 청국이 어떻게 재현되는지를 규명하고자 한다. 그 결과 『독립신문』의 편집진은 청국을 지칭하는 데 종래의 ‘중국’과 ‘중화’ 등 명칭을 배제하며, ‘청국’을 유의적으로 선택함으로써 중국을 대표하는 새로운 기호로 부각시켰다. 또는 이 기호를 둘러싸 새로운 신화를 구축하였으며, ‘청국’을 세계에서 서구와 대비된 수동적·소극적 타자, 조선에서 부정적이며 배척해야 하는 대상으로 신문지에서 재현하였다. 이는 조선시대 이래 형성된 긍정적 ‘중국’·‘중화’ 신화가 타파된 과정일 뿐만 아니라 후일 부정적 ‘청국’ 신화의 확산을 가능하게 만든 기반이라 할 수 있다. With its establishment led by Seo Jae-pil(徐載弼) in 1896, Tongnip Sinmun(The Independent) was Korea’s first unofficial newspaper which delivered the current local and international news to the public, thus reinventing people’s perception of the world outside Korea. Notably, its various columns extensively covered Qing(淸), which constructed a different image of the dynasty to the Koreans. This thesis attempts to explore how Qing was presented in Tongnip Sinmun by systematically examining the coverage of Qing done not only the ‘editorials’ but also the other columns of the newspaper and analyzing the articles as texts for their contents and narratives. In referring to Qing, the editors of Tongnip Sinmun significantly chose Cheongguk(淸國) and brought it to fore as a new symbol representing China, while ruling out such names as the previously used Jungguk(中國) and Junghwa(中華). Tongnip Sinmun constructed a new myth around the symbol, thus rendering Qing as a passive and negative other in contrast with the West, as also, an object that should be avoided in Korea. This process not only dismantled the myth of a positive Jungguk and Junghwa, which had been formed through the Joseon period but also created the basis for the later spread of the negative myth about Cheongguk.

Correlation between Topographic Parameters Obtained by Back Surface Topography Based on Structured Light and Radiographic Variables in the Assessment of Back Morphology in Young Patients with Idiopathic Scoliosis

Laura Pino-Almero,María Fe Mínguez-Rey,Rosa María Cibrián-Ortiz de Anda,María Rosario Salvador-Palmer,Salvador Sentamans-Segarra 대한척추외과학회 2017 Asian Spine Journal Vol.11 No.2

Study Design: Optical cross-sectional study. Purpose: To study the correlation between asymmetry of the back (measured by means of surface topography) and deformity of the spine (quantified by the Cobb angle). Overview of Literature: The Cobb angle is considered the gold standard in diagnosis and follow-up of scoliosis but does not correctly characterize the three-dimensional deformity of scoliosis. Furthermore, the exposure to ionizing radiation may cause harmful effects particularly during the growth stage, including breast cancer and other tumors. Methods: Patients aged 13.15±1.96 years (range, 7–17 years; n=88) with Cobb angle greater than 10° were evaluated with X-rays and our back surface topography method through three variables: axial plane (DHOPI), coronal plane (POTSI), and profile plane (PC). Pearson’s correlation was applied to determine the correlation between topographic and radiographic variables. One-way analysis of variance and Bonferroni correction were used to compare groups with different grades of scoliosis. Significance was set at p <0.01 and, in some cases, at p <0.05. Results: We detected a positive, statistically significant correlation between Cobb angle with DHOPI (r =0.810) and POTSI (r =0.629) and between PC variables with thoracic kyphosis angle (r =0.453) and lordosis lumbar angle (r =0.275). In addition, we found statistically significant differences for DHOPI and POTSI variables according to the grade of scoliosis. Conclusions: Although the back surface topography method cannot substitute for radiographs in the diagnosis of scoliosis, correlations between radiographic and topographic parameters suggest that it offers additional quantitative data that may complement radiologic study.

Bridging the Age-Related Communication Gap: An Encounter Between Senior Citizens and Communication Students Towards Social Integration

Bantugan, Brian Saludes,Bantugan, Fe C.,Urbano, Ricardo C. Center for Asian Public Opinion ResearchCollaborat 2018 Asian journal for public opinion research Vol.5 No.2

This paper is built upon an attempt to answer the question: "What can be done to facilitate social integration between the elderly of Bagac, Bataan and the communication students of St. Paul University Manila?" The research was designed as a qualitative inquiry that involved an outreach activity by 24 dominantly female students of Development Communication to the senior citizens of Bagac, Bataan (Philippines) and a reflection period involving the students. The students were tasked to pay special attention to the digital engagements and/or disengagements of the elderly to allow them to learn more about the difficulties and potential of using social media in development-related projects involving senior citizens. The actual two-hour encounter involved socialization between the elderly and the students. The students, prior to the encounter, were tasked to generate the funds, use them to acquire and prepare the gifts, develop the program during the actual encounter based on research-based guidelines, and photo document the entire activity. They were given guide questions for reflections a week after. The reflections were thematically analyzed and revealed that in order to facilitate greater social integration between the elderly and the communication students. The university should address the health and digital aversion issues that intensify the sense of isolation of the elderly experience daily. This can be done by enhancing the communication skills of the communication students in 16 areas.
