Curcumin (diferuloylmethane), a constituent of turmeric powder derived from the rhizome of Curcuma longa, has been shown to inhibit the growth of various types of cancer cells by regulating cell proliferation and apoptosis. However, a need exists to design more effective analogs because of curcumin's poor intestinal absorption. EF-24 (diphenyl difluoroketone), the monoketone analog of curcumin, has shown good efficacy in anticancer screens. However, the effects of curcumin and EF-24 on salivary gland epidermoid carcinoma cells are not clearly established. The main goal of this study was to investigate the effects of curcumin and EF-24 on cell growth and induction of apoptosis in human salivary gland epidermoid carcinoma cells. Our studies showed that curcumin and EF-24 inhibited the growth of HTB-41 cells in a dose- and time-dependent manner, and the potency of EF-24 was > 34-fold that of curcumin. Treatment with curcumin or EF-24 resulted in nuclear condensation and fragmentation in HTB-41 cells, whereas the control HTB-41 cell nuclei retained their normal regular and oval shape. Curcumin and EF-24 promoted proteolytic cleavages of procaspase-3/-7/-9, resulting in an increase in the amount of cleaved caspase-3/-7/-9 in the HTB-41 cells. Caspase-3 and -7 activities were detected in viable HTB-41 cells treated with curcumin or EF-24. These results suggest that the curcumin and EF-24 inhibit cell proliferation and induce apoptosis in HTB-41 human salivary gland epidermoid carcinoma cells, and that they may have potential properties as an anti-cancer drug therapy.

Animal Assisted Intervention (AAI) is a goal oriented intervention that intentionally includes or incorporates animals in health, education and human service for the purpose of therapeutic gains in humans. Animal assisted interventions incorporate human-animal teams in formal human service such as Animal Assisted Therapy (AAT) or Animal Assisted Education (AAE). Animal Assisted Activity (AAA) is the informal AAI often conducted on a volunteer basis by the human-animal team for motivational, educational and recreational purposes. AAI could be used for rehabilitation therapy and psychotherapy for patients with various symptoms. AAI uses animals, mostly dogs, to aid in healing patients holistically. Dogs have an overwhelming gratitude and exuberance for life and this effect on people is astounding. Furthermore, AAI has been researched and its effectiveness on patients' outcomes and healing is documented. With a soaring trend of the incorporation of complementary therapies into the mainstream of therapy and health care, animal-facilitated therapy has become a popular interest for the therapy team to integrate into a patient's plan of therapy. The purpose of this manuscript is to raise awareness about AAI and to familiarize readers with the concepts surrounding AAI so that they can be informed aids to clients who might benefit from the technique.

Porcine parvovirus (PPV), a member of the genus Parvovirus, family Parvoviridae, is a significant causative agent in porcine reproductive failure, causing serious economic losses in the swine industry. PPV is a non-enveloped virus and its capsid is assembled from three viral proteins (VP1, VP2, and VP3). The major capsid protein, VP2 is the main target for neutralizing antibodies in PPV. When VP2 was expressed in large amounts, it assembled into virus-like particles (VLPs) similar in size and morphology to the original virions. In this study, we generated the recombinant Bombyx mori nucleopolyhedrovirus (BmNPV) to express the VP2 protein. Expression of the VP2 protein was analyzed by SDS-PAGE and Western blot. The recombinant VP2 protein of approximately 64 kDa was detected by both analyses. The formation of VLP by recombinant VP2 was confirmed through transmission electron microscopy examination. The purified VP2 protein assembled into spherical particles with diameters ranging from 20 to 22 nm.

Megacities in Asia such as Seoul, Tokyo, Singapore is modern and historical at the same time. Although technologically developed and highly urbanized, these megacities’ urban fabric and life-style heavily rely on human scale – the software of the urban – as its main shaping force. This interesting mixture and contrast is what gives this city its unique characteristics. It is very motivating to find out how the software – human, community & social aspects of everyday life, rather than hardware of the city – built environment itself, drive the evolution of Seoul to such high degree. Through continuous research and workshops, the software part of the city is investigated and the lowest level elements in urban fabrication - human are looked at in two distinguish methods; computational and analogue. Differences and similarities between them are questioned, by investigating the contrast between digital and physical, virtual and actual in the thinking process. The study looks at the formation of urbanism and architecture on the level of local communities, mapping the social data, and trying to approach this idea in multiple level and perspectives.

본 연구는 방울토마토의 MA 저장시 저장기간 연장과 품질 유지를 위한 비천공 breathable 필름 종류를 구명하고자 진행되었다. 강원도에 위치한 플라스틱 하우스에서 수경재배한 토마토를 담적색기에 수확하여 5oC, 11oC, 그리고 24oC에서 산소투과도가 각기 다른 비천공 breathable 필름(10,000; 20,000; 40,000; 60,000; 80,000; 100,000 cc/m2.day.atm)과 천공필름으로 포장하여 저장하였다. 저장 중 생체중 감소율은 세가지 온도 모두에서 모든 비천공 breathable 필름처리구에서는 0.6%미만이었으나, 천공필름은 5oC는 2.93%, 11oC는 13.29%, 그리고 24oC에서는 27.24%에 달하였다. 포장내 이산화탄소와 산소 농도를 볼 때 5oC와 11oC에서 20,000 cc 필름, 24oC에서 40,000 cc 필름이 MA 조건에 근접한 수치를 보였다. 에틸렌 농도는 산소투과도가 가장 낮은 10,000 cc에서 모든 온도에서 가장 높았다. 저장 중 외관상 품질과 최종일에 측정한 경도와 당도는 5oC와 11oC의 20,000 cc 필름, 24oC의 40,000 cc 필름이 높은 수치를 나타내었다. 그러나 산도와 비타민 C 함량은 필름처리에 대한 일정한 경향을 보이지 않았다. 이상의 결과로 보았을 때, MA 저장시 포장내 대기조성과 저장 종료일의 과실 품질 등을 비교한 결과 방울토마토는 5oC와 11oC에서 20,000 cc 필름, 24oC에서는 40,000 cc 필름이 적합하였다.

본 연구는 양념 닭 가슴살의 양념 액에 귤 껍질 추출물(CPE, 2%), 양파 껍질 추출물(OPE, 2%), calcium lactate(2%), 난황 유래 phosvitin(0.1%)과 CPE, OPE 및 calcium lactate 복합처리를 첨가하였을 때 서로 다른 저장온도와 저장기간에 따른 항균 효과 및 품질 변화를 확인하고자 수행되었다. 모든 저장온도와 저장기간에서 CPE, OPE 및 복합 처리군의 총 호기성 세균 수는 대조구에 비해 유의적으로 낮게 확인되었으며, 가장 높은 미생물 생장 억제 효과가 있었던 처리군은 CPE 처리군이었다. 하지만, calcium lactate와 phosvitin 처리군의 미생물의 성장 억제 효과는 나타나지 않았다. pH의 경우, calcium lactate와 OPE 처리군은 모든 저장온도의 저장 0일차에서 대조구에 비해 유의적으로 낮은 값을 나타내었다. OPE 처리군은 모든 저장온도와 저장기간에서 다른 처리구들에 비해 유의적으로 높은 적색도를 나타내었고, CPE와 함께 저장온도에 따른 유의적 차이를 나타내지 않았다. 하지만 이러한 OPE 처리군은 풍미, 맛 및 종합적 기호도에서 다른 처리구들에 비해 유의적으로 낮은 값을 보였으며, calcium lactate와 phosvitin 처리군의 종합적 기호도는 대조구와 유의적 차이가 나타나지 않았다. 결론적으로, 양념 닭가슴살의 CPE, OPE 및 복합처리군에서 저장온도를 달리한 저장기간에 따른 미생물 억제 효과를 확인할 수 있었으나, 관능적 특성을 개선하는 방법의 개발이 필요하다고 판단된다.

We would like to report a case of leiomyoma of the ovaries in a dog. Leiomyoma is commonly seen in the vagina in dogs. However, it is a very rare neoplasm in the ovaries. As there have only been a few reported cases, this report provides valuable information on veterinary medicine and pathology. Masses found in the ovaries need to be differentiated from other ovarian tumors. Therefore, we describe the gross, histopathological, and immunohistochemical features of a case of ovarian leiomyoma in a 10-year-old female Yorkshire Terrier dog. The mass on the right of the uterus was found accidentally by pelvic ultrasonography. Laparatomy revealed a large multi-nodulated ovarian mass. Grossly, cut surfaces of the mass showed multiple firm whitish nodules in the cortex and bloody loose connective tissue in the medulla. Histopathologically, the cortex of the mass was composed of spindle cells forming interlacing fascicles. The cells had elongated, blunt-ended nuclei and eosinophilic cytoplasm as detected by hematoxylin and eosin staining. Immunohistochemical stained sections were immunoreactive for α-smooth muscle actin and desmin but negative for vimentin and S-100. Therefore, differential diagnosis confirmed leiomyoma based on morphology and positive staining for α-smooth muscle actin and desmin.

새로 조성된 간척농지의 토양개량을 위하여 새만금간척지에서 2007년부터 2011년까지 4년 동안 녹비작물 (여름철 : 세스바니아, 제주재래피, 수수×수단그라스, 겨울철 : 귀리, 호밀, 보리) 재배 및 시용이 토양이화학성에 미치는 영향을 조사하여얻은 결과는 다음과 같다.1. 녹비작물의 바이오매스 생산량은 평균 9.7~15.0ton/ha이었으며, 이 중에서 수수×수단그라스의 생산량이 가장 많았다.2. 녹비작물의 재배와 시용으로 토양유기물 함량이 1.3에서6.0g/kg로 매년 평균 1.2g/kg씩 증가하였다.3. 녹비작물의 재배와 토양환원에 의해 토양의 용적밀도가1.44에서 1.24Mg/m3로 감소하였다.4. 수수×수단그라스와 호밀의 이어짓기가 토양 용적밀도 감소에 가장 효과적이었고, 세스바니아 재배는 토양 질소함량 증가에 가장 효율적이었다.이상의 결과로 미루어 볼 때 간척지에서의 녹비작물 재배및 시용은 토양의 비옥도 요인을 일부 개선시킴으로써 간척농지 개량에 기여할 수 있을 것으로 기대된다. 앞으로 신간척지에서의 유기물과 관련된 다각적인 연구가 필요할 것으로 생각된다.

Wide-field JHKs images obtained with the SIRIUS near-infrared camera of the IRSF 1.4m telescope are used to examine the tidal structures of the spatial stellar configuration around six metal-poor ([Fe/H]< −1.0) globular clusters located within 3 kpc from the Galactic center. The radial surface density profiles are obtained from the surface photometry of the cluster images and the star counting for the photometric data. For the star counting, candidates of cluster member stars are selected with an filtering algorithm in color-magnitude diagrams. We find that the six target clusters show tidal overdensity features in the radial surface density profiles. There is a break inside the tidal radius for each cluster, and the profile in the outer overdensity region is characterized by a power law. Two- dimensional density maps of all the clusters show distorted asymmetric stellar configurations in the outer region. In five out of the six target clusters, the overdensity features are likely to be associated with the effects of the Galaxy dynamical interaction and the cluster space motions. The observed tidal configurations of stars suggest that several metal-poor clusters in the Galactic bulge are possibly surviving remnants of mergers to build the old stellar system of the Galactic bulge.

이상의 실험 결과들을 요약하면, 포르말린을 측두하악관절 내로 주입하여 발생한 염증성 통증 행위반응은 QX-314의 투여로 감소할 수 있었다. 저농도의 QX-314의 진통작용은 TRPV1 통로를 이용하여 세포막 내로 이동하여 작용이 나타났으며 고농도의 QX-314는 TRPV1 통로와 무관하게 진통작용을 나타내었다. 이와 같은 결과는 측두하악관절 장애로 인해 발생되는 염증성 통증에 QX-314가 효과적인 치료제로 사용할 수 있다는 것을 말해주며, 특히 고농도의 QX-314가 세포막을 이동하는 경로에 대한 연구가 더 진행된다면 임상에서 QX-314가 진통제로서 사용할 수 있는 계기가 될 것으로 판단된다.
