The specific activation of the immune system to control cancer growth in vivo has been a long-standing goal in cancer immunology. Whole tumor Iysates have been used either alone or combined with adjuvants to induce specific immune response in vivo. Here, we examined whether freezing/thawing (F/T) colon26-M3.1 tumor cell admixed with EN-3, glycoprotein purified from Acanthopanx Senticosus, could stimulate in vivo immunity by using a murine experimental tumor metastasis model produced by colon26-M3.1 carcinoma cells. Vaccination of mice with F/T treated colon26-M3.1 carcinoma cells in combination with EN-3 as an adjuvant resulted in a significant inhibition in tumor metastasis of mice against live colon26-M3.1 carcinoma challenge. In addition, the splenocytes from vaccinated mice exhibited a higher proliferating activity and secreted interferon-${\gamma}$. These results suggest that EN-3 can be applied to immunoadjuvant to enhance the antitumor immunity in vivo.

The twelve-protostane analogues were synthesized from alisol B 23-acetate and assessed for their in vitro antitumor activity against six different human and murine tumor cell lines. Of the compounds synthesized, 23S-acetoxy-24R(25)-epoxy-11$\beta$,23S-dihydroxyprotost-13(17)-en-3-hy-droxyimine (12) exhibited significant cytotoxic activities against A549, SK-OV3, B16-F10, and HT1080 tumor cells with $ED_{50}/$ values of 10.0, 8.7 ,5.2, and 3.1 ${\mu}g$/ml, respectively. Furthermore, 23S-acetoxy-13(17),24R(25)-diepoxy-11$\beta$-hydroxyprotost-3-one (5), 13(17),24R(25)-diepoxy-11$\beta$, 23S-dihydroxyprotostan-3-one (6), 24R,25-epoxy-11$\beta$,23S-dihydroxyprotost-13(17)-en-3-one (7), and 11$\beta$,23S,24R,25-tetrahydroxyprotost-13(17)-en-3-one (9) showed moderate cytotoxic activities against 816-F10 and HT1080 tumor cells. These results mean that a hydroxyimino group at C-3 position in the protostane-type terpene enhances cytotoxic activity.

We present an English-Korean speech translation corpus, named EnKoST-C. End-to-end model training for speech translation tasks often suffers from a lack of parallel data, such as speech data in the source language and equivalent text data in the target language. Most available public speech translation corpora were developed for European languages, and there is currently no public corpus for English-Korean end-to-end speech translation. Thus, we created an EnKoST-C centered on TED Talks. In this process, we enhance the sentence alignment approach using the subtitle time information and bilingual sentence embedding information. As a result, we built a 559-h English-Korean speech translation corpus. The proposed sentence alignment approach showed excellent performance of 0.96 f-measure score. We also show the baseline performance of an English-Korean speech translation model trained with EnKoST-C. The EnKoST-C is freely available on a Korean government open data hub site.

Aromatic diacetylenes form stable oligomeric diradicals when irradiated with UV light or heated at temperatures above their melting points. In this paper, the formation of stable diradicals is discussed, and the mechanism of polymerization in the presence of peroxide in solution, is discussed. The diphenyldiacetylene undergoes polymerization through coupling of diradicals, and not by the successive addition of radical species.

p-Fluorophenyl bicyclo[3.2.l]oct-6-en-2-yl cation (3) prepared in $FSO_3H-SO_2-CIF$ solution at -90$^{\circ}$C and examined by fluorine-19 nmr spectroscopy. The nmr data give a clear evidence for the formation of a stabilized ${\pi}$-bridging cation species in superacids. The degree of ${\pi}$delocalization in this cation is found to be inferior to the onset of nonclassical stabilization in 2-norbornenyl cation.

In deterministic and Monte Carlo transport codes, b-delayed emission is included using a group structure where all of the precursors are grouped together in 6 groups or families, but given the increase in computational power, nowadays there is no reason to keep this structure. Furthermore, there have been recent efforts to compile and evaluate all the available b-delayed neutron emission data and to measure new and improved data on individual precursors. In order to be able to perform a transient Monte Carlo simulation, data from individual precursors needs to be implemented in a transport code. This work is the first step towards the development of a tool to explore the effect of individual precursors in a fissile system. In concrete, individual precursor data is included by expanding the capabilities of the open source Monte Carlo code OpenMC. In the modified code - named Time Dependent OpenMC or OpenMC(TD)- time dependency related to β-delayed neutron emission was handled by using forced decay of precursors and combing of the particle population. The data for continuous energy neutron cross-sections was taken from JEFF-3.1.1 library. Regarding the data needed to include the individual precursors, cumulative yields were taken from JEFF-3.1.1 and delayed neutron emission probabilities and delayed neutron spectra were taken from ENDF-B/VIII.0. OpenMC(TD) was tested in a monoenergetic system, an energy dependent unmoderated system where the precursors were taken individually or in a group structure, and in a light-water moderated energy dependent system, using 6-groups, 50 and 40 individual precursors. Neutron flux as a function of time was obtained for each of the systems studied. These results show the potential of OpenMC(TD) as a tool to study the impact of individual precursor data on fissile systems, thus motivating further research to simulate more complex fissile systems.

무우품종(Raphanus sativus L.) Saxa Nova에 시들음병을 일으키는 Fusarium oxysporum f. sp. raphani (FOR)에 대해 저항성을 증가시켜 방제효과를 얻기 위하여 식물성장을 증진시키는 것으로 알려진 Pseudomonas florescens WCS374 (WCS 374), P. putida RE10 (RE10) 및 Pseudomonas sp. EN41S (EN415)을 병원균처리 토양에 단독 또는 혼합처리하여 4주간 폿트배양한 후 무우에 나타나는 외부 및 내부병징을 조사하여 처리세균에 의한 병억제 효과를 측정하였다. 내부 및 외부병징으로 대조구는 각각 46.5% 및 21.1%를 나타내었고, RE10처리는 내외병징이 각각 12.2%와 7.8%로 발병이 억제됨을 알 수 있었다. 그러나 발병억제력이 높다고 알려진 WCS374는 내외 병징이 각각 45.6%와 27.8%로 나타났다. 한편 RE10균주를 WCS374 또는 EN415 균주와 혼합하여 처리할 경우 내외 병징이 10.0-22.1% 정도이었고 EN415와 혼합처리하면 7.8-20.2%의 병징을 나타낸다. FOR의 뿌리점유율은 뿌리에서 $2.4-5.1{\times}10^3/g$였고 토양내 분포수는 $0.7-1.3{\times}10^3/g$이었다. 대조구는 뿌리에서 $3.8{\times}10^3/g$였으며 RE10의 처리는 $2.9{\times}10^3/g$로 분포수가 적었고, 3종 세균의 혼합처리는 $5.1{\times}10^3/g$으로 많이 관찰되었으나, 처리간에 통계적 차이는 없었다. 토양에서 관찰된 FOR은 부리부분 보다 그 분포 수가 적었다. 처리된 3가지 세균은 뿌리에서 $2.3-4.0{\times}10^7/g$ 범위이고, 토양에서는 $0.9-1.8{\times}10^7/g$으로 뿌리에서 관찰된 수 보다 적게 분포하였다. 뿌리부분에서 대조구나 RE10의 처리토양은 형광성 Pseudomonas spp.의 분포수가 적고 처리간에는 통계적 차이를 나타냈으나, 토양조사에서 이세균은 큰 차이를 나타내지 않았다. 뿌리에 처리된 세균과 FOR의 분포수는 토양에 처리된 것과 대조하였을 때 많았으며, 이 실험 에 사용된 RE10과 EN415은 Fusarium시들음병에 대한 기주의 저항성을 유도하는 것으로 생각된다.

Endophytes provide multifarious benefits such as promotion of plant growth and yield, suppression of phyto-pathogens, phosphate solubilising and fixation nitrogen. A study has been carried out to explore growth promotion and antifungal activities of endophytes of mulberry (Morus spp.). Endophytic bacteria were isolated from mulberry plants and studied their cultural, morphological characters, growth promotion as well as their antifungal activity against Rhizoctonia bataticola and Fusarium oxysporum , two mulberry root rot associated pathogens. Except two isolates, all bacteria were colourless and the colony size of eight isolates was small. The margin of five isolates was irregular and the consistency of three isolates was creamy, six isolates was slimy and one was mucoid. Texture of seven isolates was convex and others were flat. Eight isolates were gram positive and the rest Gram negative, five were cocci and others were bacilli (rod shaped). Four isolates were motile and all were catalase positive and only three isolates were oxidase positive. Spore staining was positive only for two isolates. The growth promotion study showed that there was significant difference in root length and seedling length. The antagonistic effect of the bacterial isolates was tested against R. bataticola showed significant (p <0.05) influence of the bacteria, days after inoculation and their interaction on the inhibition of fungal growth. The isolate En-7 completely inhibited the fungus followed by En-5 (66.67%). The bacterial isolates significantly (p <0.05) inhibited growth of F. oxysporum in PDA. The mean inhibition was higher (70.45%) in case of En-7 followed by En-8 (68.65%) and En-10 (66.44%). The study reveals that some endophytic bacteria associated with mulberry have growth promotion and antifungal activity and could be explored for promotion of mulberry growth and managing root rot disease.
