A new method for the simultaneous determination of six glucocorticoids (betamethasone, dexamethasone, prednisone, prednisolone, methylprednisolone, and flumethasone) in meats (bovine muscle, bovine liver) were established. Samples were effectively extracted using C18 cartridge with ethylacetate. Chromatographic separation was achieved using C18 column and negative electrospray ionization mass spectrometry was performed in the Multiple Reaction Monitoring mode for the effective quantitation and qualification of glucocorticoids. Acetonitrile and water (0.1% formic acid) were used as mobile phase and additive for effective electrospray ionization, and gave good chromatographic separation and mass spectrometric sensitivity. The limit of detection (LODs) and the limit of quantitation (LOQs) in spiked blank samples depending on types of matrix and pharmaceuticals were ranged from 0.2 to $1.0\;{\mu}g$/kg and 0.8 to $3.4\;{\mu}g$/kg, respectively. And the recoveries were between 89.5 to 119.6%. The established method showed good recoveries, accuracies, precisions and fast sample preparation and it will be applied to assay of glucocorticoids residues in meat.

In this study, we present simple microfluidic approach for the synthesis of monodisperse microcapsules by using droplet-based system. We generate double emulsion through single step in the microfluidic device having single junction while conventional approaches are limited in surface treatment for the generation of double emulsion. First, we have injected disperse fluid containing FC-77 oil and photocurable ethoxylated trimethylolpropane triacrylate (ETPTA) and water containing 3 wt% poly(vinyl alcohol) (PVA) as continuous phase into microfluidic device. Under the condition, we easily generate double emulsion with high monodispersity by using flow focusing. The double emulsion droplets are transformed into microcapsules under the UV irradiation via photopolymerization. In addition, we control thickness of double emulsion's shell by controlling flow rate of ETPTA. We also show that the size of double emulsions can be controlled by manipulation of flow rate of continuous phase. Furthermore, we synthesize microcapsules encapsulating various materials for the application of drug delivery systems.

Spray drying is an effective and stable process, which has been widely used to produce pharmaceutical powders. In the traditional spray drying process, it was not quite easy to control the aggregation and the size of particles. Particularly, the preparation of polymeric particles was relatively hard compared to the preparation of food and pharmaceutical ingredients, typically organic materials of small molecular weights. In this study, modification of a conventional spray dryer was tried to use electrical charge and co-axial nozzles to prepare polymeric particles. Poly(ethylene glycol) and poly (D,L-lactide-co-glycolide) were used as the inner polymeric materials, and lactose as the outer shell materials. The results showed that electrohydrodynamic spray-dried particles had a relatively uniform size and particle morphology, and the aggregation of particles could be suppressed compared to the conventional spray-dried particles. The electrohydrodynamic spray-dried powders consisted of spherical particles of $2{\sim}5{\mu}m$ diameters.

Mast cells are major effector cells associated with allergic responses. They are activated through the release of histamine, arachidonic acid, and proinflammatory cytokines. We investigated the effect of nodakenin, derived from the roots of Angelica gigas Nakai, on mast cell degranulation and on an allergic response in an animal model. We also investigated the effect of nodakenin on expression of multiple cytokines. Nodakenin suppressed the release of ${\beta}$-hexosaminidase, a marker of degranulation, as well as the expression of interleukin IL-4 and TNF-${\alpha}$ mRNA. Nodakenin inhibited the passive cutaneous anaphylaxis (PCA) reaction in ICR mice in a dose-dependent manner. These results suggest that nodakenin can inhibit mast cell degranulation through the inhibition of IL-4 and TNF-${\alpha}$ mRNA expression, and that nodakenin may potentially serve as an anti-allergic agent.

희귀질환이란 일반적으로 그 유병율이 인구 일만 명당 5명 이하인 질환을 말한다. 세계에는 약 7,000여종의 희귀질환이 알려져 있고 학술지에 매 주 대략 5종의 새로운 희귀질환이 보고되고 있다. 희귀 의약품(orphan drug)이란 희귀질환치료제 또는 수익성이 없어 개발을 기피하는 일반질환 치료제로서 정부가 지정한 의약품을 말한다. Orphan 의약품의 개발에는 많은 장점이 있다. Orphan 의약품으로 정부의 지정을 받으면 세금감면을 통한 연구비 지원, 임상시험 비용 지원, 신약허가 심사비 면제, 시장독점권 부여 등의 특혜가 주어진다. 희귀질환의 대부분은 단순한 유전적 결함에 의하는 경우가 많아 치료제의 표적발견이 비교적 쉬우므로 개발 성공률이 높고, 임상시험기간이 짧으며, 시판허가를 받을 확률이 높아 연구개발비용이 적게 든다. 그 결과 전세계 orphan 의약품 시장은 최근 매년 6%씩 성장하여 2014년에는 약 1,120억달러의 시장을 형성할 것으로 추정된다. Orphan 의약품 시장은 현재 매년 8.9%씩 성장하고 글로벌 시장의 51%를 점유하는 미국을 중심으로 확장되어 가고 있으며, 총매출액의 64.3%가 유전자재조합의약품에 의한 것으로 알려져 있다. 이러한 의약품시장의 변화와 사회적 요구에 부응하여 한국 또한 희귀질환 치료제 개발의 활성화를 위해 재정적 지원체계를 구축하고, 허가관리를 개선하며, 법률적 제도를 완비하는 과정에 있다. 현재 희귀질환의 치료적 타겟을 찾아 신물질이나 기존의 약물을 발굴하는 과정이 주로 대학이나 연구 중심 병원에서 이루어지고 있다. 제도가 잘 정립되어 있는 미국 시장을 겨낭하여 orphan 의약품 개발을 전략적으로 수행한다면 큰 성공을 거둘 수 있을 것으로 기대된다.

The prognosis of gastric cancer with hepatic metastasis is very poor, even though several treatment modalities exist, such as surgical resection. Indeed, a standard therapy has not been established in such patients. Recently, attempts were made to treat hepatic metastasis of gastric cancer with radiofrequency (RF), which was originally used in primary or metastatic liver cancer. RF has been reported to show similar survival compared to surgical resection and is emerging as a new treatment modality even though it is still not conclusive with respect to efficacy and safety due to the paucity of reports. A prospective study is warranted to evaluate the efficacy of RF in the treatment of gastric cancer with hepatic metastasis compared with conventional modalities.

In this paper, we present a case study for a drug repositioning simulation based on distributed supercomputing technology that requires highly efficient processing of large-scale computations. Drug repositioning is the application of known drugs and compounds to new indications (i.e., new diseases), and this process requires efficient processing of a large number of docking tasks with relatively short per-task execution times. This mechanism shows the main characteristics of a Many-Task Computing (MTC) application, and as a representative case of MTC applications, we have applied a drug repositioning simulation in our HTCaaS system which can leverage distributed supercomputing infrastructure, and show that efficient task dispatching, dynamic resource allocation and load balancing, reliability, and seamless integration of multiple computing resources are crucial to support these challenging scientific applications.

Objective Medication is one the most important things in treatment for children, but prescribing traditional herbal medicine for them is very difficult. Therefore, we made 4 new forms of oriental herbal medicine that has a better taste, smell, and color. These new forms also have a texture that make medicine easier to chew. Methods We made up a question of 20 children visiting $\bigcirc\;\bigcirc$ university hospital. Results and Conclusions 1. Children preferred liquid or pill type of herbal medicine. 2. The preference sensory test of the traditional medicine and new form of medicine had not much difference. 3. On the test for preferences, it resulted as they liked the 4th form of new medicine which was with little bit more of sweet and sour taste, and the 3rdformwithnewcolors. 4. They hated traditional herbal medicine of the taste, smell, color, sensation of texture of material.

This study aims to examine experiences of homeless risk factor before becoming the homeless focusing during their childhood period. This study underscore their victimization experience in their previous life with life history interviews of 60 homeless adults. As a result, this study identified various individual homeless risk factors they experienced for a long time. Also the risk factors were interactive, amplified and affect becoming homeless in the end. Moreover the results proved different characteristics between the group according how often they experienced homeless risk factors. These results show that the individual factors emerging homeless also start early stages of their life and those were invincible misfortune and victimization. These findings suggest that the government policy and proactive intervention in order to prevent homeless in the early stage need to be established and have more concerns about high risk youth.
