We successfully label-free and real-time detect the capture processes of human immunoglobulin G (IgG)/goat anti-human IgG and mouse IgG/goat anti-mouse IgG antigen-antibody pairs with different concentrations using the oblique-incidence reflectivity difference (OIRD) method,and obtain the interaction kinetics curves and the interaction *** experimental results prove that the OIRD method is a promising technique for label-free and real-time detection of the biomolecular interaction processes and achieving the quantitative information of interaction kinetics.

通过对电子商务的物流信任度渐进控制模型设计,进行网络实体对象的信任度评级,提高对商家的定量评估性能。传统的电子物流信任度控制模型采用自相关函数分析的模型设计方法,由于自相关特征分析的主观性较大,评价效果不好。提出一种基于互相关准则的电子物流信任度渐进控制模型。首先构建电子物流的资源数据库结构模型,构建用户信任评估机制与网络控制模型。采用DOI(Degree of Interest)互相关准则描述用户对资源的信任度评价,基于互相关准则,两个用户共同作出对彼此信任值模型的归一化评价。仿真实验表明,采用该模型,对电子物流信任度具有较好的渐进控制性能,信任度评价准确,估计精度较高,实现了基于互相关准则的电子物流信任度渐进控制,提高对电子物流商家的监管能力。

Sinistral portal hypertension （SPH） is usually caused by pancreatic pathology and is characterized bysplenic vein thrombosis with or without portal vein thrombosis.1 The increased pressure caused by splenic vein occlusion is transmitted via the short gastric and gastroepiploic veins to the portal system. The reversal of blood flow in the left gastric vein results in gastric varices. In patiems with SPH, especially those with occlusion of both the splenic and portal veins, the main or even the only pathway of splenic venous return to the portal vein is via the gastric varices, and these patiems require special management during gastric surgery.

甲烷是对全球温升贡献仅次于二氧化碳的温室气体,且其全球增温潜势是CO_(2)的80倍以上。在全球变暖和大气中甲烷含量不断增长的背景下,完全催化氧化大气甲烷对于减缓温室效应和全球变暖具有重要价值。然而,由于甲烷具有较高的结构稳定性,在温和条件下将其催化氧化一直面临巨大的挑战。本文综述了近年来甲烷完全氧化在热催化、光催化以及光热协同催化三种反应条件下的研究进展,热催化中高温增大了能耗并加速了催化剂的失活,开发低温反应条件下的催化剂已经成为甲烷完全热催化的重点;光催化提供了一种常温常压条件下利用光能氧化甲烷的方法,但是相对热催化来说反应速率较低;光热协同催化在光能和热能的协同作用下,可实现温和条件下的甲烷高效完全催化氧化,表现出潜在的应用前景。本文就三种反应催化剂的发展进行综述,系统分析了不同反应的原理,以及不同反应条件下甲烷完全催化氧化的优势与不足,同时总结了催化氧化甲烷所面临的挑战,并提供潜在的解决方案,期望为今后的甲烷氧化研究提供借鉴。

Background Functional reconstruction of the jaw defect due to tumor resection poses a challenging problem in maxillofacial surgery. The osteocutaneous fibula free flap in combination with simultaneous or second stage insertion of dental implants has exhibited growing popularity for such reconstructions. This study was aimed at evaluating the clinical status and the success rates of dental implants inserted in fibula-free flaps for orofacial reconstruction following ablation of tumors. Methods We conducted a clinical follow-up study based on 29 patients after oral tumor surgery, who received vascularized fibula bone grafts and endosseous implants for functional jaw reconstruction during a 5-year period. The follow-up protocol included clinical examination and radiological evaluation. The clinical records of the patients were reviewed retrospectively. Information on treatment modalities, dentition, implant parameters, and prostheses was collected and analyzed. Results In general, a high primary stability for implants placed into the free fibula grafts was achieved. The 1-year and 5-year cumulative survival rates of the implants were 96% and 91%, respectively, using the Kaplan-Meier method. The 1-year and 5-year cumulative success rates of implants respectively. The main reasons for failure of the dental proliferation. The fibula flap presents many advantages for implant-supported prosthetic rehabilitation difficult. placed into the fibula bone grafts were 95% and 87%, replants were infection, tumor recurrence and soft tissue implant placement, but its limited height sometimes makes Conclusions Vascularized fibula bone grafts provide a firm basis for the placement of dental implants in jaw reconstruction. Implants placed in fibula bone grafts were shown to integrate normally. The double-barrel technique, or increasing the height of the fibula flap by vertical distraction osteogenesis before implant placement in the mandible, is desirable from a functional and esthetic
