[Method] The first polar body extrusion rate, oocyte glutathione （GSH） content, positive rate of brilliant cresyl blue （BCB） staining and development potential of activated oocytes or fertilized oocytes were employed as main indicators to investigate the effects of follicular mural granulosa cell （MGC） coculture on cytoplasmic maturation of cumulus cell-removal oocytes （Denuded Oocyte, DO）. [Result] According to in vitro maturation results, compared with DO group, the first polar body extrusion rate of porcine oocytes in DO＋MGC group was not significantly different, but the nuclear maturation process was improved and was more similar to that in COC （cumulus-oocyte complex） group. Detection of GSH content in mature oocytes showed that there was no significant difference between DO＋ MGC group （optical density of 1 053.67） and COC group （optical density of 1 426.00） or between DO＋MGC group and COC＋GC group （optical density of 1 541.00）, however, GSH content in mature oocytes of DO group （optical density of 724.67） was significantly lower than that of COC group and COC＋GC group （P0.05）. Detection of glucose-6-phosphate dehydrogenase （G6PDH） activity showed that there was no significant difference in BCB positive oocyte rate between DO ＋MGC group （88.26% ） and COC group （92.75%） or between DO＋MGC group and DO group （82.86% ）, however, BCB positive oocyte rate of DO group was significantly lower than that of COC group （P0.05）. Furthermore, the cleavage rate and blastocyst rate of activated mature oocytes derived from DO ＋MGC group （94.98% and 43.67% , respectively） were significantly higher than those from DO group （52.54% and 8.97%, respectively） （P0.05）, and were not significantly different compared with those from COC group （97.11% and 38.30%, respectively）. In addition, the cleavage rate of fertilized oocytes derived from DO＋MGC group （72.65%） showed no significant difference compared with that from DO group （63.59%）, but the blastocyst rate of DO＋MGC group was significantly higher than that of DO group （9.88%） （P0.05）. [Conclusion] MGC coculture can significantly improve the in vitro cytoplasmic maturation quality of denuded porcine oocytes, thereby enhancing the subsequent developmental potential.展开更多

Until the late Tang Dynasty （A.D. 848-907）, sheer Pala style of eastern India appeared in Dunhuang, however, whether those East India painting style still belong to Tubo remain for further discussion. The art style of East India appeared in Dunhuang during from the late Tang Dynasty to the early period of Northern Song Dynasty, probably propagated from the ways other than Tubo, and this art style was deemed as the one has nothing to do with Tibet＇s art in this study.展开更多

Based on the art knowledge ...Dunhuang murals are gems of Chinese traditional art. This paper demonstrates a simple, yet powerful method to automatically identify the aesthetic visual style that lies in Dunhuang murals. Based on the art knowledge on Dunhuang murals, the method explicitly predicts some of possible image attributes that a human might use to understand the aesthetic visual style of a mural. These cues fall into three broad types: ① composition attributes related to mural layout or configuration; ② color attributes related to color types depicted; ③ brightness attributes related to bright conditions. We show that a classifier trained on these attributes can provide an efficient way to predict the aesthetic visual style of Dunhuang murals.展开更多

A method...In mausoleum murals, existing bubbles are one kind of the most harmful defects for the repair and protection of relics. For this reason, it is necessary to detect bubbles, especially the ones with small size. A method to detect the small bubbles with enhanced terahertz （THz） images is proposed. To simulate the bubbles in the mausoleum murals, circular grooves have been hidden in the plaster and then measured by the THz reflected time domain spectroscopy imaging system. To observe the small bubbles in murals, a comprehensive enhancement algorithm is adopted to process the obtained THz images. With the enhanced method, the circular grooves in the murals can be observed clearly, even for the circular groove with a diameter of 1.5 mm. The results indicate that the proposed comprehensive method can be used to detect the tiny defects of murals.展开更多

The application of the model demonstrated that it can repeat to great extent the phenomenon of myocardial bridge compressing mural coronary artery that results in abnormal hemodynamic characteristic. The in vitro simulation experiment indicates that the anomaly of normal stress, circumferential stress and wall shear stress mainly occurs in the proximal end. As the oppression level increases, the mean proximal stress and the oscillatory value (maximum-minimum) increase obviously. The experimental model for heart-mural coronary artery-myocardial bridge provides a method to study relationship between myocardial bridge and atherosclerosis.展开更多

文摘The traditional woodcut New Year pictures in Shanxi have a long history, which is a classic folk art work in China. The branch of culture it represents is the traditional culture branch in the Yellow River basin, which flourished in the Ming and Qing Dynasties, among which the Woodcut New Year pictures in the south of Shanxi are the most famous. This kind of wood-block New Year picture technology is very rich in connotation, including the use of traditional Chinese mural painting powder, powder is born in the Sui and Tang dynasties mural painting an important tool, which shows that powder in the field of Chinese traditional art to participate in the creation of a significant position, artistic value is very high. In this paper, we will specifically discuss the traditional Shanxi New Year wood-block pictures and traditional mural paintings, and deeply understand the basic concepts and characteristics of the two. Finally, this paper studies the internal subtle relationship between the two from three aspects: the remains of the works, the time of painting and literary illustrations.
文摘Ceramic relief mural is a contemporary landscape art that is carefully designed based on human nature,culture,and architectural wall space,combined with social customs,visual sensibility,and art.It may also become the main axis of ceramic art in the future.Taiwan public ceramic relief murals(PCRM)are most distinctive with the PCRM pioneered by Pan-Hsiung Chu of Meinong Kiln in 1987.In addition to breaking through the limitations of traditional public ceramic murals,Chu leveraged local culture and sensibility.The theme of art gives PCRM its unique style and innovative value throughout the Taiwan region.This study mainly analyzes and understands the design image of public ceramic murals,taking Taiwan PCRM’s design and creation as the scope,and applies STEEP analysis,that is,the social,technological,economic,ecological,and political-legal environments are analyzed as core factors;eight main important factors in the artistic design image of ceramic murals are evaluated.Then,interpretive structural modeling(ISM)is used to establish five levels,analyze the four main problems in the main core factor area and the four main target results in the affected factor area;and analyze the problem points and target points as well as their causal relationships.It is expected to sort out the relationship between these factors,obtain the hierarchical relationship of each factor,and provide a reference basis and research methods.

文摘[Objective] This study aimed to improve the in vitro maturation quality of denuded porcine oocytes and provide scientific basis for establishing a stable and efficient denuded oocyte culture system. [Method] The first polar body extrusion rate, oocyte glutathione （GSH） content, positive rate of brilliant cresyl blue （BCB） staining and development potential of activated oocytes or fertilized oocytes were employed as main indicators to investigate the effects of follicular mural granulosa cell （MGC） coculture on cytoplasmic maturation of cumulus cell-removal oocytes （Denuded Oocyte, DO）. [Result] According to in vitro maturation results, compared with DO group, the first polar body extrusion rate of porcine oocytes in DO＋MGC group was not significantly different, but the nuclear maturation process was improved and was more similar to that in COC （cumulus-oocyte complex） group. Detection of GSH content in mature oocytes showed that there was no significant difference between DO＋ MGC group （optical density of 1 053.67） and COC group （optical density of 1 426.00） or between DO＋MGC group and COC＋GC group （optical density of 1 541.00）, however, GSH content in mature oocytes of DO group （optical density of 724.67） was significantly lower than that of COC group and COC＋GC group （P0.05）. Detection of glucose-6-phosphate dehydrogenase （G6PDH） activity showed that there was no significant difference in BCB positive oocyte rate between DO ＋MGC group （88.26% ） and COC group （92.75%） or between DO＋MGC group and DO group （82.86% ）, however, BCB positive oocyte rate of DO group was significantly lower than that of COC group （P0.05）. Furthermore, the cleavage rate and blastocyst rate of activated mature oocytes derived from DO ＋MGC group （94.98% and 43.67% , respectively） were significantly higher than those from DO group （52.54% and 8.97%, respectively） （P0.05）, and were not significantly different compared with those from COC group （97.11% and 38.30%, respectively）. In addition, the cleavage rate of fertilized oocytes derived from DO＋MGC group （72.65%） showed no significant difference compared with that from DO group （63.59%）, but the blastocyst rate of DO＋MGC group was significantly higher than that of DO group （9.88%） （P0.05）. [Conclusion] MGC coculture can significantly improve the in vitro cytoplasmic maturation quality of denuded porcine oocytes, thereby enhancing the subsequent developmental potential.
文摘During A.D. 776 to 848, Dunhuang was occupied and ruled by Tubo political power, a special painting style, spread via the Tibetan silk road, appeared at same time, and which is related to the art style of India and Nepal; It is worth noting that the Tibetan painting style during this period have no relative unified model actually, especially the mural and the silk painting preserved in Library Cave, the painting style of which had obvious difference between each other, and the reason behind this is very hard to explain. Until the late Tang Dynasty （A.D. 848-907）, sheer Pala style of eastern India appeared in Dunhuang, however, whether those East India painting style still belong to Tubo remain for further discussion. The art style of East India appeared in Dunhuang during from the late Tang Dynasty to the early period of Northern Song Dynasty, probably propagated from the ways other than Tubo, and this art style was deemed as the one has nothing to do with Tibet＇s art in this study.

文摘Dunhuang murals are gems of Chinese traditional art. This paper demonstrates a simple, yet powerful method to automatically identify the aesthetic visual style that lies in Dunhuang murals. Based on the art knowledge on Dunhuang murals, the method explicitly predicts some of possible image attributes that a human might use to understand the aesthetic visual style of a mural. These cues fall into three broad types: ① composition attributes related to mural layout or configuration; ② color attributes related to color types depicted; ③ brightness attributes related to bright conditions. We show that a classifier trained on these attributes can provide an efficient way to predict the aesthetic visual style of Dunhuang murals.

文摘In mausoleum murals, existing bubbles are one kind of the most harmful defects for the repair and protection of relics. For this reason, it is necessary to detect bubbles, especially the ones with small size. A method to detect the small bubbles with enhanced terahertz （THz） images is proposed. To simulate the bubbles in the mausoleum murals, circular grooves have been hidden in the plaster and then measured by the THz reflected time domain spectroscopy imaging system. To observe the small bubbles in murals, a comprehensive enhancement algorithm is adopted to process the obtained THz images. With the enhanced method, the circular grooves in the murals can be observed clearly, even for the circular groove with a diameter of 1.5 mm. The results indicate that the proposed comprehensive method can be used to detect the tiny defects of murals.

文摘BACKGROUND Recently,a technique has been developed to use magnetic resonance enterography(MRE)for the evaluation of small bowel motility.The hypothesis was that assessment of the motility index(MI)should reflect differences in motility between clinical conditions.AIM To aim of the present observational,cross-sectional study was to evaluate the use of the MI in daily clinical practice.METHODS All consecutive patients aged 18-70 years who were referred for MRE at the Department of Radiology during a 2-year period were asked to participate.Healthy volunteers were included as controls.MRE was prepared and conducted in accordance with clinical routines.On the day of examination,all the participants had to complete the visual analog scale for irritable bowel syndrome(IBS)and IBS-symptom severity scale.Maps of MI were calculated from dynamic MR images.ANOVA was used to evaluate differences in MI between groups,classified as healthy,Crohn’s disease,ulcerative colitis,IBS,other assorted disorders and dysmotility.Logistic and linear regression were applied to the MI values.All medical records were scrutinized for medical history.RESULTS In all,224 examinations were included(inclusion prevalence 76.3%),with 22 controls and 202 patients.There was a significant difference in the MI of the jejunum(P=0.021)and terminal ileum(P=0.007)between the different groups.The MI was inversely associated with the mural thickness of the terminal ileum in men(P<0.001)and women(P=0.063)after adjustments,and tended to be lower in men than in women(P=0.056).Subjectively observed reduction of motility on MRI was accomplished by reduced MI of terminal ileum in men(P<0.001)and women(P=0.030).In women,diarrhea was inversely associated with the MI of the jejunum(P=0.029),and constipation was positively associated with the MI of the terminal ileum(P=0.039).CONCLUSION Although MIs differ across diseases,a lower MI of the terminal ileum is mainly associated with male sex and an increased mural thickness.Symptoms are weakly associated with the MI.

文摘BACKGROUND Anaplastic carcinoma mural nodules in ovarian mucinous tumors are very rare.This study aimed to report the morphological characteristics,molecular detection results,clinical treatment and prognosis of three ovarian mucinous tumors with mural nodules of anaplastic carcinoma.CASE SUMMARY The pathomorphological features,molecular detection results,clinical treatment and prognosis of anaplastic carcinoma mural nodules were described in three cases.In case 1,sarcoma-like mural nodules(SLMNs)coexisted with anaplastic carcinoma mural nodules.No mutation was found in mucinous tumors.KRAS mutation was found in anaplastic carcinoma nodules and heterotypic cells were found in SLMNs.In case 2,KRAS mutation occurred in the mucinous epithelium and BRAF mutation occurred in mural nodules.In case 3,both mural nodules and mucinous tumors had the same KRAS mutation and a morphological transition between them was observed.All three patients died within 2 years,whether receiving chemotherapy or not.CONCLUSION Anaplastic carcinoma mural nodules may develop from dedifferentiation of mucinous tumors or are unrelated to mucinous tumors.
文摘An experimental model for heart-mural coronary artery-myocardial bridge was established based on the theory of hemodynamics. The application of the model demonstrated that it can repeat to great extent the phenomenon of myocardial bridge compressing mural coronary artery that results in abnormal hemodynamic characteristic. The in vitro simulation experiment indicates that the anomaly of normal stress, circumferential stress and wall shear stress mainly occurs in the proximal end. As the oppression level increases, the mean proximal stress and the oscillatory value (maximum-minimum) increase obviously. The experimental model for heart-mural coronary artery-myocardial bridge provides a method to study relationship between myocardial bridge and atherosclerosis.
