Clear cell odontogenic carcinoma (CCOC), a very rare neoplasm located mostly in the mandible, has been regarded as a benign tumor. However, due to the accumulation of case reports, CCOC has been reclassified as a malignant entity by the World Health Organization. Patients with CCOC present with regional swelling and periodontal indications with variable pain, often remaining misdiagnosed for a long period. CCOC has slow growth but aggressive behavior, requiring radical resection. Histologic analysis revealed the monophasic, biphasic, and ameloblastic types of CCOC with clear cells and a mixed combination of polygonal and palisading cells. At the molecular level, CCOC shows the expression of cytokeratin and epithelial membrane antigen, along with markers that assign CCOC to the sarcoma family. At the genetic level, Ewing sarcoma breakpoint region 1-activating transcription factor 1 fusion is regarded as the key feature for identification. Nevertheless, the scarcity of cases and dependence on histological data delay the development of an efficient therapy. Regarding the high recurrence rate and the potential of distant metastasis, further characterization of CCOC is necessary for an early and accurate diagnosis.

The global mushroom industry has grown rapidly in recent years in terms of beneficial effects, market value, and demand. India has a wide range of agro-climatic conditions and is largely an agricultural country with a cultivated area of about 4.37 %, generating about 620 million tons of agro waste annually. Mushroom cultivation not only helps recycle agro wastes, but also fills the nutritional gap prevalent among a large population of India. Recently, government industrial policy and creative innovation has promoted research and other endeavors aiming towards the cultivation of mushrooms. Mushroom cultivation in India was initiated in Solan, in the mid-sixties. Mushroom cultivation has been successful in temperate regions of the Himalayas, the Western Ghats, and the hills of northeast India. Recently, many unemployed people have begun to adopt mushroom cultivation as a means of self-employment. It is high time that Indian mushroom cultivators and consumers became aware of the nutritional and medicinal values of cultivated and wild species of mushrooms. The total mushroom production in India between 2010 and 2017 was approximately 0.13 million tons, accounting for a 4.3% increase in the average growth rate of mushrooms per annum. In particular, the total production of white button mushrooms is the highest, with a share of about 73% of total mushroom production. In this review article, we have analyzed the current scenario of the Indian mushroom industry and its contribution to the economic growth of the country.

This study evaluated the protective effects of a combination of eight B. abortus recombinant proteins that were cloned and expressed into a pMal vector system and DH5α: nucleoside diphosphate kinase (rNdk), 50S ribosomal protein (rL7/L12), malate dehydrogenase (rMDH), DNA starvation/stationary phase protection protein (rDps), elongation factor (rTsf), arginase (rRocF), superoxide dismutase (rSodC), and riboflavin synthase subunit beta (rRibH). The proteins were induced, purified, and administered intraperitoneally into BALB/c mice. The mice were immunized three times at weeks 0, 2, and 5 and then infected intraperitoneally (IP) with 5×104 CFU of virulent B. abortus 544 one week after the last immunization. The spleens were collected and the bacterial burden was evaluated at four weeks post-infection. The results showed that this combination produced a significant reduction of the bacterial burden in the spleen with a log reduction of 1.01 compared to the PBS group. Cytokine analysis revealed induction of the cell-mediated immune response in that TNF (tumor necrosis factor) and proinflammatory cytokines IL-6 (Interleukin 6) and MCP-1 (macrophage chemoattractant protein-1) were elevated significantly. In summary, vaccination with a combination of eight different proteins induced a significant protective effect indicative of a cell mediated immune response.

최근 수목 병해충을 방제, 예방하기 위해 나무주사법이 많이 사용되고 있다. 나무주사법은 기상에 상관없이 약제처리가 가능하며, 약제사용량 감소와 천적등 비표적 생물에 대한 영향을 줄일 수 있다는 장점이 있다. 하지만 현재 국내에서 나무주사법은 산림 해충을 대상으로만 등록, 적용되어 있을 뿐, 과수에 등록된 제품은 없다. 과수에 나무주사법이 적용되기 위해서는 농약잔류와 약효에 대한 연구가 필요하다. 본 연구에서는 복숭아(천중도)에 Acetamiprid 10% SL을 나무주사 후, 잔류성과 약효를 조사하여 실용가능성을 확인하였다. 약제가 나무주사된 나무는 복숭아 벚나무깍지벌레(Pseudaulacaspis prunicola)에 대하여 방제효과가 있으나, 가지별로 불균일한 약효와 잔류성을 보여 향후 수형, 흉고직경 등을 고려한 나무주사제의 처리법 최적화에 대한 연구가 지속적으로 필요할 것으로 생각된다.

Xyrosaris Meyrick, 1907 is a small genus of the family Yponomeutidae, established by Meyrick (1907) for its type species Xyrosaris dyropa Meyrick, 1907. A total of nine species were recognized in the world. Most of species of the genus have been described by Meyrick at the early 20th century. Up to date, X. lichneuta Meyrick, 1918 has been reported from Korea. In the present study, we review the genus Xyrosaris from Korea, with two new species: X. sp.1 and X. sp.2. Key to species, illustrations of adult, male and female genitalia, diagnosis and short description are provided.

The genus Meganola (Nolidae, Nolinae) was established by Dyar (1898), with the type species Meganola conspicua Dyar, 1898, from America (Type locality: Texas, Colorado, Arizona). This genus comprises 80 species described in the Palaearctic and Oriental region. In this study, genus Meganola Dyar is reviewed from Korea, with description of a new species. We redescribed 12 species and one new species. Illustrations of adults and genitalia of all Korean species are provided, with a key to the genus of Meganola based on the male genitalia.

The mesenchymal stem cells (MSCs) that reside in dental tissues hold a great potential for future applications in regenerative dentistry. In this study, we used human dental pulp cells, isolated from the molars (DPCs), in order to establish the organoid culture. DPCs were established after growing pulp cells in an MSC expansion media (MSC-EM). DPCs were subjected to organoid growth media (OGM) in comparison with human dental pulp stem cells (DPSCs). Inside the extracellular matrix in the OGM, the DPCs and DPSCs readily formed vessel-like structures, which were not observed in the MSC-EM. Immunocytochemistry analysis and flow cytometry analysis showed the elevated expression of CD31 in the DPCs and DPSCs cultured in the OGM. These results suggest endothelial cell-prone differentiation of the DPCs and DPSCs in organoid culture condition.

The purpose of this study is to improve practical skill evaluation method of mushroom - trained certified technician's practical skill evaluation which is one of national qualification tests based on national incompetency standards. One of the current National Competency Standards (NCS), mushroom - trained certified technician uses NCS based practical assessment method. In order to improve the current practical evaluation method, we try to improve practical evaluation method based on field customized problem solving ability and improve the practical evaluation method, various evaluation methods should be constructed. On the purpose of identify the diversity and problems of the evaluation method, the experts of the group consultation, the mushroom-related research institute and the related industry collaborated to identify the problems of the actual mushroom - trained certified technician practicum test, This study on the evaluation improvement method was carried out. In this study, the contents of practical test of the current mushroom traits were analyzed and the trends of the latest mushroom industry were widely reflected.
