Neolignans such as obovatol, honokiol, and magnolol have been previously reported to show various biological activities including anti-inflammation and antitumor effects. This is the first demonstration on the in vivo antitumor effect of obovatol on human colorectal carcinoma SW620 cells. Nude mice were implanted with SW620 cells and fed with vehicle or 5mg/kg/d dose of obovatol for 20 days. Obovatol inhibited tumor growth that accounted for 50% decrease in tumor volume and 44.6% decrease in tumor weight at the end of the experiment without any adverse health effect. In nude mice bearing SW620-incubated tumor, obovatol exhibited more potent antitumor activity than honolkiol. In addition, DNA flow cytometric analysis shows that obovatol progresses to apoptosis as detected by flow cytometry after double staining with annexin V and propidium iodide. Thus, we suggest that obovatol is a potent inducer of cell apoptosis in SW620 cells, and a potent antitumor agent. 相似文献

Flexible Cu(In,Ga)Se2 (CIGS) solar cells are developed on polyimide (PI) foil by using a three‐stage co‐evaporation method. To deposit CIGS on a PI substrate, low temperature deposition process (below 440 °C) is investigated. By optimizing the three‐stage process, power conversion efficiency (PCE) values of 12.1% and 13.6% are obtained at maximum process temperatures of 400 °C and 440 °C, respectively (without anti‐reflection coating). The CIGS absorber deposited at 400 °C is grown with (220)/(204) rather than (112) as its dominant growth orientation, accompanied by highly homogeneous crystal structure and phases. Admittance spectroscopy reveals that the defect levels were lower in the CIGS absorber with (220)/(204) dominant growth orientation, which could have contributed to the PCE of 12.1%. The CIGS solar cell deposited at a temperature of 440 °C exhibits worse defect characteristics compared to that fabricated at 400 °C. However, the CIGS solar cell fabricated below 440 °C exhibited marginal double‐grading of Ga/(Ga + In) in the absorber layer, which resulted in an improved PCE of 13.6%. This result implies that at a temperature below 440 °C, the double‐grading of Ga/(Ga + In) is the more dominant factor causing the PCE improvement above 13%. 相似文献

This study reports the first two clinical cases of spirometrosis caused by Spirometra sp. in cats in Korea. In these two cases, the cats vomited, and long proglottids of tapeworm were recovered. The sick cats presented with anorexia and lethargy. However, they unexpectedly showed no diarrhea, which is the main symptom of spirometrosis. Based on a fecal floatation test as well as morphological and molecular analyses, the parasite was diagnosed as Spirometra sp. The 2 cases were treated with praziquantel. This study suggests regular monitoring of health and deworming in companion animals, even when animals are well cared for, with regular preventive medication. Additionally, spirometrosis should be considered in the differential diagnosis in cases of gastrointestinal symptoms in Spirometra endemic areas. 相似文献
