Acacetin, which is present in damiana (Turnera diffusa ) and black locust (Robinia pseudoacacia ), has several pharmacologic activities such as antioxidant, anti-inflammatory, and anti-proliferative effects on cancer cells. However, the effect of acacetin on head and neck cancers has not been clearly established. This study aimed to examine the effects of acacetin on cell growth and apoptosis induction in FaDu human pharyngeal carcinoma cells. These were investigated by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay, Live/Dead cell assay, 4′,6-diamidino-2-phenylindole dihydrochloride staining, caspase-3 and caspase-7 activation assay, and immunoblotting in FaDu cells. Acacetin induced FaDu cell death in a dose-dependent manner, with an estimated IC50 value of 41.9 µM, without affecting the viability of L-929 mouse fibroblasts as normal cells. Acacetin treatment resulted in nuclear condensation in the FaDu cells. It promoted the proteolytic cleavage of procaspase-3, -7, -8, and -9 with increasing amounts of the cleaved caspase isoforms in FaDu cells. Acacetin-induced apoptosis in FaDu cells was mediated by the expression of Fas and activation of caspase-8, caspase-3, and poly (ADP-ribose) polymerase. Immunoblotting showed downregulation of the anti-apoptotic mitochondrial proteins Bcl-2 and Bcl-xL, but upregulation of the mitochondria-dependent pro-apoptotic proteins Bax and Badin FaDu cells after acacetin treatment. These findings indicate that acacetin inhibits cell proliferation and induces apoptotic cell death in FaDu human pharyngeal carcinoma cells via both the death receptor-mediated extrinsic apoptotic pathway and the mitochondria-mediated intrinsic apoptotic pathway.

Ficus carica L. (fig ) is one of the first cultivated crops and is as old as humans. This plant has been extensively used as a traditional medicine for treating diseases, such as cough, indigestion, nutritional anemia, and tuberculosis. However, the physiological activity of fig leaves on oral cancer is as yet unknown. In this study, we investigated the anticancer effect of methanol extracts of Ficus carica (MeFC) and the mechanism of cell death in human FaDu hypopharyngeal squamous carcinoma cells. MeFC decreased the viability of oral cancer (FaDu) cells but did not affect the viability of normal (L929) cells, as determined by 3-[4,5-dimethylthiazol-2-yl]-2,5-diphenyltetrazolium bromide assay and Live and Dead assay. In addition, MeFC induced apoptosis through the proteolytic cleavage of procaspase-3, -9, poly (ADP-ribose) polymerase (PARP), downregulation of Bcl-2, and upregulation of Bax, as determined by 4′,6-diamidino-2-phenylindole dihydrochloride staining and western blot analysis. Moreover, a concentration of MeFC without cytotoxicity (0.25 mg/mL) significantly suppressed colony formation, a hallmark of cancer development, and completely inhibited the colony formation at 1 mg/mL. Collectively, these results suggest that MeFC exhibits a potent anticancer effect by suppressing the growth of oral cancer cells and colony formation via caspase- and mitochondrial-dependent apoptotic pathways in FaDu human hypopharyngeal squamous carcinoma cells. Therefore, the methanol extract of Ficus carcica leaves provide a natural chemotherapeutic drug for human oral cancer.

HPT research studies and practices have been largely conducted in the corporate setting, leaving education as a neglected context despite its strong emphasis on performance in teaching, learning, and school management. In this study, we examine the application of the HPT standards and their effects on Korean teachers’ performance goal achievement for students. With HPT standards, we also investigate the interaction effect of teacher tenure on the relationship among HPT standards and goal achievement. The Hayes Process Model is adopted to examine the second-stage moderated mediation model. The findings support that the principle standards positively mediate the effect of the process standards on the teachers’ goal achievement, and teacher tenure moderates the HPT standards’ effects on goal achievement. The practical and theoretical implications of the results are discussed, as well as limitations and future research suggestions

Spontaneous motion is one of the most basic event types, but different languages use varying patterns to express it. For example, English usually encodes path information in prepositional phrases or adverbial particles, while Korean maps path information onto verbs (Talmy, 1985). This study predicts that this typological difference would affect English spontaneous motion expressions produced by Korean learners and analyzes two English-language speech corpora, one, the data from native speakers (600 recordings), and the other, data from L1-Korean learners of English (400 recordings). It finds that the learners significantly underuse satellite-framed patterns, but not verb-framed patterns, compared with the native speakers, suggesting that the L1 plays a role in their L2 production. The satellite-framed patterns, however, account for the greatest portion of spontaneous motion expressions in the L2 corpus, suggesting the dominant effect of input on L2 production. These findings lead to pedagogical implications concerning preventing L1 interference and fostering input-based L2 acquisition.

The present study was designed to determine the effect of barn or cycle of grazing on changes of biochemical metabolites in prepartum and changes of milk composition in postpartum of dairy cows. For this purpose, a total of sixteen 25 months old Holstein primiparous dairy cows were allocated in two groups (n=8) with an average body weight of 571.61 ± 35.30 kg (Barn) and 578.10 ± 39.20 kg (Grazing). The study was conducted from June 2018 to October 2018. Results revealed that barn raised dairy cows had a higher increase in their serum albumin and calcium level on day 14 prepartum. However, the level of palmitic acid, saturated fatty acid increased significantly, and the level of fat, oleic acid, γ-linoleic acid, arachidonic acid and unsaturated fatty acids decreased significantly in barn raised dairy cow’s milk on day 14 postpartum. There were no significant differences observed with respect to all other biochemical metabolites, fatty acids and minerals between barn raised and cycle grazing dairy cows during prepartum and postpartum. Our study results could serve to a better understanding of barn raised cow with respect to changes of biochemical metabolites in prepartum and changes of milk composition, fatty acids and minerals content in grazing dairy cows in postpartum for estimating their physiological status.

Trifolium pratense leaves (red clover) has been used in Oriental and European folk medicine for the treatment of whooping cough, asthma, and eczema, and is now being used to treat and alleviate the symptoms, such as hot flushes, cardiovascular health effects that occur in postmenopausal women. However, relatively little scientific data is available on the physiological activity of this plant. Therefore, in this study, we investigated the anti-cancer activity of T. pratense leaves using methanol extract of T. pratense leaves (MeTP) on human FaDu hypopharyngeal squamous carcinoma cells. MeTP inhibited the viability of FaDu cells by inducing apoptosis through the cleavage of procaspase- 3, -7, and -9 and poly (adenosine diphosphate ribose-ribose) polymerase (PARP), downregulation of Bcl- 2, and upregulation of Bax, as determined by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, Live & dead assay, 4’6-diamidino-2-phenylindole stain, fluorescence-activated cell sorting analysis, and Western blot analysis. In addition, colony formation was slightly inhibited when FaDu cells were treated with a non-cytotoxic concentration (0.125 mg/mL) of MeTP and almost completely inhibited when cells were treated with 0.25 mg/mL MeTP. Collectively, these results indicate that MeTP induced cell apoptosis via caspase- and mitochondrial-dependent apoptotic pathways, and inhibited colony formation of cancer cells in FaDu human hypopharyngeal squamous carcinoma cells. These findings suggest MeTP should be considered for clinical development as a chemotherapeutic option in oral cancer.

The Port of Pyeong Taek is located on the west coast, meaning that the difference between the rise and fall of tide is great (flood tide 1.8 to 2.9 knots, ebb tide 1.6 to 2.9 knots). Due to mainly N~NW’ly strong winds & high waves during winter, navigating as well as loading & discharging vessels must focus on cargo handling. The strong tidal and wind forces in the Port of Pyeong Taek can push an LNG carrier away from its berth, which will end up causing forced disconnection between the vessel’s cargo line and shore-side loading arm. The primary consequence of this disconnection will be LNG leakage, which will lead to tremendous physical damage to the hull and shore-side equipment. In this study, the 125K LNG Moss Type ship docked at No. 1 Pier of the Pyeong Taek is observed, and the tension of the mooring line during cargo handling is calculated using a combination of wind and waves to determine effective mooring line and mooring line priority management. As a result if the wind direction is 90° to the left and right of the bow, it was found that line monitoring should be performed bearing special attention to the Fore Spring Line, Fore Breast Line, and Aft Spring Line.

Insect killing fungus Beauveria bassiana has been widely studied as a biological control agent. However, many studies have been focused on lab or field-based management. Herein this work, comparison of three B. bassiana strains was investigated under a molecular level. The whole genome sequences of ERL836, JEF-007 were analyzed by PacBio (35.5 Mb of ERL836 and 36.5 Mb of JEF-007) and ARSEF2860 referenced from GenBank (33.7 Mb). To compare the three strains, virulence, thermotolerance and chemical resistance were assayed. The transcriptomes of non-infecting B. bassiana and infecting B. bassiana against western flower thrips were analyzed using RNA-seq. This work can provide that genome features, functions, morphology and gene expression could be different under the molecular level, even if in the same species.

The global biopesticide market was estimated to become about 4% of the total crop protection market in 2015, mainly due to variability of their efficacy, narrow spectrum or difficulties in long-term storage. Therefore, many people focus on overcoming these issues as a big trend. Suggested solutions include the investigation of synergy between microorganisms, the use of genetic engineering, improving the pesticide life shelf, etc. As a result, biopesticides market has grown by more than 17% over the last decade. In this context and aiming to develop new entomopathogenic fungi–based pest management tools, we constructed a fungal library by isolating insect pathogenic fungi from soil. A total of 581 isolates belonging to 35 species were isolated and characterized. Beauveria bassiana was the most abundant, representing 38.55% of the total strains, followed by Metharizium anisopliae (22.55%) and bubillosa (8.6). …% of the total isolates were highly virulent against Tenebrio molitor killing most of the treated insects in 2 to 3 days.

Japanese pine sawyer, Monochamus alternatus, is the main pest that mediates pine wilt nematode, Bursaphelenchus xylophilus, that causes serious damage to pine forests. In this study, we studied the strategy to control M. alternatus using entomopathogenic fungi. The fungi were collected from soil by an insect-baiting method and two fungal isolates (Metarhizium anisopliae JEF-197 and JEF-279) showed high virulence against M. alternatus. The Metarhizium isolates were evaluated for insecticidal activity against M. alternatus by spray treatment on live pine trees and wintering trees, and the M. anisopliae JEF-197 showed high insecticidal activity. In addition, the interaction of fungi and M. alternatus were analyzed by RNA-seq. This result can contribute to the development of insect control agents using entomopathogenic fungi.

고온기 화색발현이 우수하고 연중생산이 가능한 수출용 스프레이국화 신품종을 육성하기 위하여 충남농업기술원 화훼 연구소에서 2010년 분홍색의 모본 ‘Borami’를 방임수분하였다. 2011년에 종자를 파종하였고, 이중 화형과 화색이 우수한 개체를 선발하여 ‘SP11-148-01’로 계통명을 부여하였다. 2011년부터 2013년까지 주년 생산성을 위해 전조, 자연, 차광재배로 특성을 각각 검정하였고, 생육 및 개화특성은 화형과 화색이 비슷한 자주색 스프레이국화인 ‘Kingfisher’를 대조품종으로 조사하였으며, 2013년 ‘Yes Ruby’로 품종등록 출원하였다. ‘Yes Ruby’는 자주색의 설상화와 연녹색의 통상화로 가을 작형 개화기는 10월 24일로, ‘Kingfisher’의 10월 29일에 비해 빨랐다. ‘Yes Ruby’의 초장과 줄기굵기는 각각 94.9cm와 7.7mm로 ‘Kingfisher’의 89.2cm와 6.4mm보다 컸다. ‘Yes Ruby’의 꽃 직경은 6.2cm로 ‘Kingfisher’의 5.0cm보다 컸으며, 꽃잎수도 ‘Yes Ruby’가 25.7개로 ‘Kingfisher’의 23.3개보다 많았다. 착화수는 두 품종 모두 비슷하였으며, 흰녹병 저항성은 ‘Yes Ruby’가 2단계, ‘Kingfisher’는 3단계의 감염 정도를 나타내어 흰녹병에 대한 저항성이 높은 것으로 나타났다. 재배상 유의사항은 ‘Yes Ruby’는 겨울철 균일한 개화가 이뤄지지 않아 겨울철 야간온도를 18℃ 이상으로 관리해줌으로써 균일개화를 유도할 수 있다. 또한 생장억제제인 Daminozide을 처리함으로써 설상화수를 늘려 볼륨감 높은 꽃봉오리를 형성할 수 있어 고온기에도 화색발현이 우수하고 연중생산이 가능하여 안정적 수출을 통한 농가소득 증대에 기여할 수 있을 것으로 기대된다.

Exosomes are Nano-sized lipid vesicles secreted from mammalian cells containing diverse cellular materials such as proteins, lipids, and nucleotides. Multiple lines of evidence indicate that in saliva, exosomes and their contents such as microRNAs (miRNAs) mediate numerous cellular responses upon delivery to recipient cells. The objective of this study was to characterize the different expression profile of exosomal miRNAs in saliva samples, periodically isolated from a single periodontitis patient. Unstimulated saliva was collected from a single patient over time periods for managing periodontitis. MicroRNAs extracted from each phase were investigated for the expression of exosomal miRNAs. Salivary exosomal miRNAs were analyzed using Affymetrix miRNA arrays and prediction of target genes and pathways for its different expression performed using DIANA-mirPath, a web-based, computational tool. Following the delivery of miRNA mimics (hsa-miR-4487, -4532, and -7108-5p) into human gingival fibroblasts, the expression of pro-inflammatory cytokines and activation of the MAPK pathway were evaluated through RT-PCR and western blotting. In each phase, 13 and 43 miRNAs were found to be differently expressed (|FC| ≥ 2). Among these, hsa-miR-4487 (|FC|=9.292005) and hasmiR- 4532 (|FC|=18.322697) were highly up-regulated in the clinically severe phase, whereas hsa-miR-7108-5p (|FC|= 12.20601) was strongly up-regulated in the clinically mild phase. In addition, the overexpression of miRNA mimics in human gingival fibroblasts resulted in a significant induction of IL-6 mRNA expression and p38 phosphorylation. The findings of this study established alterations in salivary exosomal miRNAs which are dependent on the severity of periodontitis and may act as potential candidates for the treatment of oral inflammatory diseases.
