Park, Jeu,Huh, Jin Young,Oh, Jiyoung,Kim, Jong In,Han, Sang Mun,Shin, Kyung Cheul,Jeon, Yong Geun,Choe, Sung Sik,Park, Jiyoung,Kim, Jae Bum Cold Spring Harbor Laboratory Press 2019 Genes & development Vol. No.

<P>In this study, Park et al. set out to elucidate the mechanism by which adipose-resident invariant natural killer T cells (iNKT) cells impact adipose tissue remodeling in obesity. Using in vitro and ex vivo approaches, the authors found that, in obesity, adipose iNKT cells can kill hypertrophic and pro-inflammatory adipocytes via FasL-Fas-dependent apoptosis, thus providing new insight into the role adipose iNKT cells play in promoting healthy adipose tissue remodeling.</P><P>In obesity, adipose tissue undergoes dynamic remodeling processes such as adipocyte hypertrophy, hypoxia, immune responses, and adipocyte death. However, whether and how invariant natural killer T (iNKT) cells contribute to adipose tissue remodeling are elusive. In this study, we demonstrate that iNKT cells remove unhealthy adipocytes and stimulate the differentiation of healthy adipocytes. In obese adipose tissue, iNKT cells were abundantly found nearby dead adipocytes. FasL-positive adipose iNKT cells exerted cytotoxic effects to eliminate hypertrophic and pro-inflammatory Fas-positive adipocytes. Furthermore, in vivo adipocyte-lineage tracing mice model showed that activation of iNKT cells by alpha-galactosylceramide promoted adipocyte turnover, eventually leading to potentiation of the insulin-dependent glucose uptake ability in adipose tissue. Collectively, our data propose a novel role of adipose iNKT cells in the regulation of adipocyte turnover in obesity.</P>

Over the last f ive decades, the UN and OECD/DAC have strongly urged member states to comply with global aid norms to improve aid effectiveness. To what extent are the global aid norms actually put in practice in countries that have pledged themselves to comply with these norms? Norm life cycle theory explains the internalization of global norms as legalization, institution-building, and official policies at the national level. This study supplements the norm lifecycle theory by subdividing the process of norm internalization into the policy formation stage and the post-implementation stage at the national level and empirically examines it by employing five criteria: ODA/GNI ratio; aid to LDCs; the ratio of grant to loan; aid-untying; and fragmentation. The results show that some aid norms are well accepted and implemented at both stages while other norms are neither addressed in official aid policies nor put into practice.

Jiyoung Park,Sea-Kwan Oh,Hyun-Jung Chung,Hyun-Jin Park,Hye Young Park,Hye-Sun Choi,Hong-Sig Kim 한국식품영양과학회 2021 한국식품영양과학회 학술대회발표집 Vol.2021 No.10

Resistant starch (RS), a type of prebiotic, presents various functions, such as increasing satiety, improving colon environment, blood sugar and insulin response, and reducing and maintaining weight. Most rice cultivars comprise less than 1% of RS, whereas “Dodamssal” (DDS) contains about 10% in white rice. In this study, we aimed to elucidate the starch characteristics in various rice cultivars with different amylose contents developed by the National Institute of Crop Science and enhance use of RS-containing DDS brown rice as a health-promoting low-glycemic-index (GI) food. Non-digestible starches (NDS) and native starches (NS) were isolated from four rice cultivars: Baegokchal (BOC), Ilmi (IM), Mimyeon (MM), and DDS. MM- and DDS-derived NS showed high amylose and low rapidly digestible starch contents as well as high slowly digestible starch and RS proportions. The BOC, IM, and MM starch crystals showed A-type X-ray diffractometry patterns. However, the DDS granules displayed a C-type crystallinity pattern with a predominant B-type and convex spherical shape. All the IM and BOC starches were hydrolyzed, with no remaining NDS residues. MM and DDS NDS showed longer average amylopectin chain length but lower molecular weight and viscosity than the NS. The DDS starch had the lowest digestibility and highest RS content, showing its potential to prevent obesity and hyperglycemia. Roasting conditions, which increase the RS content in DDS, were explored in the 180∼300°C and 10∼30 min ranges. We compared the intermediate-amylose ‘IM’ and high-amylose ‘Goami4’ and ‘DDS’ cultivars. The IM RS content was not significantly different before and after roasting. The Goami4 RS content was significantly higher before roasting and significantly lower at temperatures above 210°C than that of DDS (P<0.05). The starch hydrolysis index and expected GI (eGI) were higher in the following order: IM, Goami4, and DDS, regardless of the roasting treatment. The sensory evaluation for color, flavor, bitter taste, and sweetness yielded high scores for DDS at 240°C for 10 min and 210°C for 30 min. The results indicate that DDS is a suitable cultivar for low-GI powder meal preparation. Upon analyzing the roasted DDS and 60∼200 mesh-passed brown rice flour (BRF) quality characteristics, the average particle size, hydrolysis index, and eGI showed significantly lower values for DDS than for Ilpumbyeo (P<0.05). The DDS RS content was 13% regardless of standard sieve or particle size. Therefore, we concluded that DDS is a valuable health food, as it is easily ground evenly when processed into BRF, contains RS, and has a low eGI. To improve the DDS BRF quality and establish the processing protocol, we steamed rough rice (SRRD) and brown rice (SBRD) for 30 min, then dried and roasted them at 240°C for 10 min. The particle size, crystallinity, thermal properties, RS content, and BRF digestion rate were compared with those of similarly treated IM (SRRI) and single-roasted DDS (RD). In the case of SRRI and SBRD, exhibiting a high order of gelatinization degree, significant differences with large average particle size, high digestion rate, and eGI, as well as low RS content were observed (P<0.05). SRRD showed significant differences in the fine powder particle distribution range with the highest proportion, RS content, and low eGI, although the gelatinization degree increased compared with RD (P<0.05). Therefore, SRRD, with improved BRF quality, could be potentially used as a carbohydrate source for developing functional powdered food for health improvement.

The therapeutic effects of Yongdamsagan-tang on autoimmune hepatitis models

Park, Jiyoung,Kim, Hayeon,Lee, In-Seung,Kim, Kang-Hoon,Kim, Yumi,Na, Yun-Cheol,Lee, Jang-Hoon,Jang, Hyeung-Jin EDITIONS SCIENTIFIQUES ELSEVIER 2017 BIOMEDICINE AND PHARMACOTHERAPY Vol.94 No.-

<P><B>Abstract</B></P> <P>Autoimmune hepatitis (AIH) is an immunity disorder that is the result of antibodies in the liver tissue of the patient that are attacked by activated immune cells due to an unknown cause. In this study, we aimed to investigate the anti-inflammatory effect of Yongdamsagan-tang (YST) extracts and confirm effects on autoimmune hepatitis models as the therapeutic agent using the YST extracted by various solvents. YST, a mixture of 11 herbal extracts, is known in traditional Korean medicine as a widely used treatment for inflammatory diseases. We proposed the AIH-condition in vitro model by the addition of recombinant IL-17A and then observed several markers linked to AIH symptoms, including an increase of IL-6 expression, lipid accumulation, and fibrosis. In AIH-condition hepatic cell model, YST reduced IL-6 expression and lipid accumulation caused by treatment of IL-17 combination in hepatocyte cells. Also, YST blocked several activated fibrosis factors including transforming growth factor-β (TGF- β1), collagen type 1 (Col-α1(I)), and α-smooth muscle actin (α-SMA) in liver stellate cells. Furthermore, pretreatment with YST protected hepatic damage and reduces histological injury by suppressing apoptosis mediator and inflammatory cytokines expression in concanavalin A (Con A)-induced autoimmune hepatitis mice model. The findings here improve our understanding of YST extracted by 80% ethanol, suggesting that YST can be used as a therapeutic treatment for AIH.</P>

Comparison of the effects of isoflurane versus propofol- remifentanil anesthesia on oxygen delivery during thoracoscopic lung lobectomy with one-lung ventilation in dogs

Jiyoung Park,Hae-Beom Lee,정성목 대한수의학회 2018 Journal of Veterinary Science Vol.19 No.3

This study compared effects of isoflurane inhalation (ISO) and propofol-remifentanil combined total intravenous anesthesia (TIVA) on oxygenation during thoracoscopic lung lobectomy with 30-min one-lung ventilation (1LV). Thoracoscopic right middle lung lobectomy was performed in ten dogs divided into ISO and TIVA groups, and cardiopulmonary parameters were measured with blood gas analysis. Throughout the study, isoflurane was inhaled up to 1.5%, and the infusion rates of propofol and remifentanil were 0.2 to 0.4 mg/kg/min and 6 to 11 mg/kg/h, respectively. Cardiac index was not affected in the ISO group, but it increased during 1LV in the TIVA group. There were significant alterations in arterial oxygen pressure, arterial oxygen saturation, oxygen content, and shunt fraction associated with 1LV in each group. However, oxygen delivery did not decrease significantly due to open chest condition, 1LV, or surgical maneuver in either group, rather it increased during 1LV in the TIVA group. All parameters showed no significant difference between groups. Pulmonary vascular resistant index was unaffected in both groups, and there was no difference between groups except in re-ventilation phase. Accordingly, the effect of both anesthetic regimens on oxygenation was not different between groups and can be used with short-term 1LV for thoracoscopic lung lobectomy in dogs.

본 연구는 척수 장애인의 글쓰기를 도와줄 수 있는 글쓰기 보조기구 개발을 위해 이 기능이 필요한 척수장애인들의 신체적 특징을 고려한 제품을 설계하기 위한 요소들을 분석하고자 한다. 척수장애인들의 대부분 갑작스런 사고로 장애를 가진 20~30대 연령이 많은 비중을 차지하며 레저 활동이 활발해 짐에 따라 증가를 보이고 있는 추세이다. 20~30대는 사회생활을 필요로 하는 연령대이기 때문에 사회생활 중 반드시 자필의 글쓰기가 필요한 경우가 있다. 본 연구에서는 척수 장애인 관련 문헌조사를 통해 척수 장애인의 손기능에 대한 고찰과 글쓰기 보조도구 개발 시 고려해야 할 제품 설계 요소를 추출하였다. 추출된 제품 설계 요소와 제품 제작 시 고려해야 할 기타사항 및 요구 조사를 바탕으로 제품이 제작된다면 척수 장애인 좀 더 사용하기 편리한 제품을 만들 수 있을 것으로 기대된다.

Preparation and Electrochemistry of Platinum Nanoparticles Deposited on Ionic-Liquid-Decorated Reduced Graphene Oxide with an Enhanced Methanol Catalytic Activity

Park, Jiyoung,Park, Soo-Jin,Kim, Seok The Electrochemical Society 2014 Journal of the Electrochemical Society Vol.161 No.5

<P>Ionic-liquid-decorated reduced graphene oxide (IL-RGO) composites were synthesized by NaBH<SUB>4</SUB> reduction. Platinum nanoparticles (Pt NPs) were then supported on the IL-RGO via a polyol process. Ionic liquid, an amphoteric ion used as an additive agent to stabilize metal nanoparticles, can also prevent the aggregation of the RGO. Compared to Pt/RGO, Pt/IL-RGO composites exhibit better electrocatalytic activity for a methanol oxidation when the mass ratio of IL to RGO is 3:1. The structural properties of the Pt nanocomposites were investigated using transmission electron microscopy, X-ray photoelectron spectroscopy, FT-IR spectroscopy, and X-ray diffraction. The results showed that the IL-RGO support could successfully introduce Pt nanoparticles with a crystallite size of about 2.5 nm. The electrochemical properties of Pt nanocomposites were confirmed using cyclic voltammetry. The electrochemical test results indicated that the electrocatalytic activities and long-term stability of the Pt/IL-RGO composites were better than those of the Pt/RGO composites. This was attributed to the increase in the electrochemical surface area after a modification with ionic liquids.</P>
