Tandem device architectures offer a route to greatly increase the maximum possible power conversion efficiencies(PCEs)of polymer solar cells,however,the complexity of tandem cell device fabrication(such as selecting bandgaps of the front and back cells,current matching,thickness,and recombination layer optimization)often result in lower PCEs than are observed in single-junction *** this study,we analyze the influence of front cell and back cell bandgaps and use transfer matrix modeling to rationally design and optimize effective tandem solar cell structures before actual device *** approach allows us to estimate tandem device parameters based on known absorption coefficients and open-circuit voltages of different active layer materials and design devices without wasting valuable time and *** this approach,we have investigated a series of wide bandgap,high voltage photovoltaic polymers as front cells in tandem devices with PTB7-Th as a back *** this way,we have been able to demonstrate tandem devices with PCE of up to 12.8%with minimal consumption of valuable photoactive materials in tandem device *** value represents one of the highest PCE values to date for fullerene-based tandem solar cells.

【目的】探究松材线虫入侵对寄主马尾松的影响。【方法】以4年生马尾松(Pinus massoniana)为试材,以皮接法接入5 000条松材线虫的马尾松为处理组[PWN(+)组],以接入无菌水的马尾松为对照组[PWN(-)组],基于多组学(表型组学、转录组学、宏基因组学、代谢组学)量化松材线虫入侵马尾松14 d后的变化。【结果】与PWN(-)组相比,PWN(+)组活性氧(ROS)含量和H_(2)O_(2)含量分别显著上升3.2倍和1.7倍(Pko03030)、DNA复制蛋白通路(BR:ko03032);代谢组上、下调的差异代谢物分别有365个和351个,PWN(+)组中根皮素、熊去氧胆酸、羧苄青霉素等物质的含量会增加以抵御松材线虫的侵染,差异显著的代谢物显著富集于ABC转运蛋白通路、花生四烯酸代谢通路、类黄酮生物合成通路、甘油磷脂代谢通路。【结论】当松材线虫入侵马尾松时,寄主会启动一系列复杂的防御反应。这些反应并非孤立存在,而是通过多种机制协同作用,共同应对松材线虫的侵染。上述结果有助于从多组学角度阐明松材线虫入侵对马尾松的影响,并为松材线虫病害诱导的森林衰退和寄主植物马尾松之间的相互作用提供依据。

Lactoferrin （LF） and retinoic acid （RA） are enriched in colostrum, milk, and mucosal tissues. We recently showed that LF-induced IgA class switching through binding to betaglycan （transforming growth factor-beta receptor III, TpRIII） and activation of canonical TGF-p signaling. We investigated the combined effect of LF and RA on the overall IgA response. An increase in IgA production by LF was further augmented by RA. This combination effect was also evident in Ig germ-line α （GLa） transcription and GLa promoter activity, indicating that LF in cooperation with RA increased IgA isotype switching. We subsequently found that RA enhanced TβRIII expression and that this increase contributed to LF-stimulated IgA production. In addition to the IgA response, LF and RA in combination also enhanced the expression of the gut-homing molecules C-C chemokine receptor 9 （CCR9） and a4β7 on B cells. Finally, peroral administration of LF and RA enhanced the frequency of CCR9＋ IgA＋ plasma cells in the lamina propria. Taken together, these results suggest that LF in cooperation with RA can contribute to the establishment of gut IgA responses.

Comparative effects of plant oils and trans-fat on blood lipid profiles and ischemic stroke in rats

Ltd. Cheonan Chungnam Republic of Korea

Since plant oils are believed to be better than animal fats for cerebrovascular and cardiovascular diseases, the effects of various plant oils and trans-fat on blood lipid profiles and ischemic stroke were investigated. Sprague- Dawley rats were fed a diet containing the oils or trans-fat, and then body weights, blood lipids, and effects on brain infarction and physical dysfunction induced by middle cerebral artery occlusion （MCAO） were analyzed. All the oils and trans-fat, except perilla oil, significantly increased body fats and body weight gain. Sesame oil and trans-fat specifically increased blood cholesterols and triglycerides, respectively, while perilla oil decreased both cholesterols and triglycerides. Perilla oil not only attenuated cerebral infarction, but also restored locomotor activity and rota-rod performances of MCAO rats. It is suggested that perilla oil among oils and fats could be the first choice to reduce the risk of metabolic syndrome and ischemic stroke.

Evaluation of anatomical considerations in the posterior maxillae for sinus augmentation

引用

World Journal of Clinical Cases 2014年第11期2卷 683-688页

作者： Ji-eun Lee Seong-Ho Jin Youngkyung ko Jun-Beom Park Department of Periodontics Seoul St. Mary’s Hospital College of Medicine The Catholic University of Korea Seoul 137-701South Korea

The edentulous posterior maxilla is considered a clinical challenge during dental implant treatment for many dental practitioners. This is because its insufficient bone quality, deficient alveolar ridge, spiny ridges, undercuts, and sinus pneumatization are often encountered after tooth loss. To overcome these problems, several approaches have been developed and are currently used, including sinus augmentation and bone augmentation. Today, two main procedures of sinus floor elevation for dental implant placement are in use: a two-stage technique using the lateral window approach, and a onestage technique using a lateral or a crestal approach. In this study, we deal with the anatomic relations ofthe structures of the maxillary sinus during sinus augmentation. These anatomical findings can help in complications and potential injuries of the maxillary sinus procedures. It can be suggested that pre-operative evaluation is helpful for diagnosis and treatment planning and minimizing complication during the surgery.
