Growth factor receptors and related signalling pathways as targets for novel treatment strategies of hepatocellular cancer

Growth factors and their corresponding receptors are commonly overexpressed and/or dysregulated in many cancers including hepatocellular cancer （HCC）. Clinical trials indicate that growth factor receptors and their related signalling pathways play important roles in HCC cancer etiology and progression, thus providing rational targets for innovative cancer therapies. A number of strategies including monoclonal antibodies, tyrosine kinase inhibitors （＂small molecule inhibitors＂） and antisense oligonucleotides have already been evaluated for their potency to inhibit the activity and downstream signalling cascades of these receptors in HCC. First clinical trials have also shown that multi-kinase inhibition is an effective novel treatment strategy in HCC. In this respect sorafenib, an inhibitor of Raf-, VEGF- and PDGF-signalling, is the first multi-kinase inhibitor that has been approved by the FDA for the treatment of advanced HCC. Moreover, the serine-threonine kinase of mammalian target of rapamycin （mTOR） upon which the signalling of several growth factor receptors converge plays a central role in cancer cell proliferation, roTOR inhibition of HCC is currently also being studied in preclinical trials. As HCCs represent hypervascularized neoplasms, inhibition of tumour vessel formation via interfering with the VEGF/VEGFR system is another promising approach in HCC treatment. This review will summarize the current status of the various growth factor receptor-based treatment strategies and in view of the multitude of novel targeted approaches, the rationale for combination therapies for advanced HCC treatment will also be taken into account.

Coordinated control strategy for robotic-assisted gait training with partial body weight support

Walking is the most basic and essential part of the activities of daily living. To enable the elderly and non-ambulatory gait-impaired patients, the repetitive practice of this task, a novel gait training robot(GTR) was designed followed the end-effector principle, and an active partial body weight support(PBWS) system was introduced to facilitate successful gait training. For successful establishment of a walking gait on the GTR with PBWS, the motion laws of the GTR were planned to enable the phase distribution relationships of the cycle step, and the center of gravity(COG) trajectory of the human body during gait training on the GTR was measured. A coordinated control strategy was proposed based on the impedance control principle. A robotic prototype was developed as a platform for evaluating the design concepts and control strategies. Preliminary gait training with a healthy subject was implemented by the robotic-assisted gait training system and the experimental results are encouraging.

It is not the only decisive factor but to interweave with other tensions in the development of technology.

On the Edge of Malfeasance： Informal African Immigrant Traders in the/ohannesburg Inner City, South Africa

Admittedly, the stratospheric rise of Informal African Immigrant Traders （IAIT） in the Johannesburg inner city within a climate of discrimination, harassment, hostility, and xenophobia has engendered survival strategies which border on the illegal and underground. Based on an in-depth interview study of 40 IAIT, operating in the Johannesburg inner city and specialising in clothes, cellphone and accessories, household goods, fruits and vegetables, and a courier company, this paper posits that the registered and unregistered IAIT operate side by side with the latter operating from undesignated sites, either bribing or deceitful evading the Johannesburg Metropolitan Police （JMP）. Is this the characteristic of IAIT in the Johannesburg inner city？ Ostensibly, the success of challenging the institutional regulatory regime points to the possibility of African immigrant traders existing on the edge of impropriety or lawlessness. To this end, there is a need for comprehensive policy initiatives starting from the national and cascading to the provincial and municipality levels that will effectively address and manage urban informality, including the activities of the IAIT, failing which these will fuel operations outside the regulatory regimes and the mushrooming of the underground economic activities.

The Actual Trends of Olive Growing in Albania

The olive tree （Olea Europaea） owns the status of national patrimony in Albania. In the past, olive plantations were dictated by Agricultural Policies, where olive trees were cultivated mainly in marginal lowland areas and hills. The highest efficiency in olive production is reached mainly in the Southern and Central regions of the country. After 1990s, olive farming has been highly impacted due to shifts in the economic system. Its interest in the economical aspect is going to be very important in the near future. The government has developed a national scheme for the intensification of olive farming by increasing the planted area by 60,000 ha, or in total to 20 million olive trees. Our study presents an overall view of actual trends of olive farming, olive industry, subsequent environmental problems resulting from farming and olive mills by-products, and finally the role that the government has to play in that sector,

China＇s Industries in the Beginning of Its 12th Five-Year Plan Period

Complex international and domestic economic scenarios and the short cyclical nature of macroeconomic policies characterizes the beginning year of the 12th Five- Year Plan period, it reflects the difficult policy choices that arise among three major regulatory targets ,for growth, structure, and prices. In the transitional period of intertwined challenges, a spirit of commitment and dedication to real industries will allow China to occupy vantage points in world manufacturing and become an industrial power in the real sense. To a certain extent the beginning year of the 12th Five-Year Plan period （2011-2015）, while.fraught with challenges and pain, marks a departure from cutthroat competition to quality growth for Chinese enterprises and entrepreneurs. From 2012, China＇s industrial and market economic systems will both head towards more sophisticated stages of development. China ＂s industries will develop along environmentally sustainable, delicate, high-end, IT-based and service-oriented paths, while expediting the country＇s economic restructuring, industrial upgrade capabilities and its pursuit of innovative industrialization, and it will do so with strides more remarkable than ever before in its history.

Structural Change in China's Emergency Management: Theoretical Generalizations

From the perspective of systems thinking, China＇s emergency management structure can be analyzed in terms of five dimensions： social change, governance transformation, government framework, policy system and operational mechanisms. On the basis of comparative analysis, we discuss structural change across these dimensions by targeting our research on major disasters in the decade from SARS in 2003 to the Lushan earthquake in 2013. Overall, consolidation and evolution coexist in China＇s emergency management structure. At present, structural consolidation has the upper hand, but there are also forces driving structural evolution. Using inductive logic and the comparative method, we arrive at a theoretical generalization about the structural consolidation of China＇s emergency management, demonstrating its ＂comet-shaped＂ structure and ＂comet-tair＇ effect. On this basis, we put forward our theoretical propositions. We believe that the underlying reason for the developmental predicament facing emergency management in China today is that it goes ahead on its own, divorced from structure. Its further development must go back to structure and change with the times, with a view to promoting the structural evolution of China＇s emergency management.

The Reform and Development of the Decision-making System in Contemporary China

The decision-making system is the backbone of China＇s political system and a crucial factor determining its development. The decision-making system with the CPC lying at the core results from the CPC＇s long history of leading China＇s revolution and establishing the People＇s Republic of China; therefore it has historical rationality. Decision-making was centralized over the period from the foundation of the PRC to reform and opening up. This centralized decision-making system had faults such as a low level of specialized division oflabor, low institutionalization, an undue emphasis on experience, a closed decision-making process and the absence of any self-correcting and adjustment mechanisms. The reform of China＇s decision-making system in the post-reform period has attached much importance to promoting democratic, scientific and law-based decision-making with regard to decision~ making structures, modes and mechanisms. Practice proves that this reform has successfully met the challenges arising from rapid social and economic transition. Viewed from the perspective of political development, it involves an evolution from personal to democratic, from experience-based to scientific, from centralized to decentralized, from closed to open, from passive to active participation and from non-institutionalized to institutionalized decision-making. A decision-making model has gradually taken shape that is characterized by CPC domination, participation by multiple entities, scientific proof, open process, and law-based operation.

Energy efficiency and area spectral efficiency tradeoff for coexisting wireless body sensor networks

The coexistence of wireless body sensor networks(WBSNs) is a very challenging problem, due to strong interference, which seriously affects energy consumption and spectral reuse. The energy efficiency and spectral efficiency are two key performance evaluation metrics for wireless communication networks. In this paper, the fundamental tradeoff between energy efficiency and area spectral efficiency of WBSNs is first investigated under the Poisson point process(PPP) model and Matern hard-core point process(HCPP) model using stochastic geometry. The circuit power consumption is taken into consideration in energy efficiency calculation. The tradeoff judgement coefficient is developed and is shown to serve as a promising complementary measure. In addition, this paper proposes a new nearest neighbour distance power control strategy to improve energy efficiency. We show that there exists an optimal transmit power highly dependant on the density of WBSNs and the nearest neighbour distance. Some important properties are also addressed in the analysis of coexisting WBSNs based on the IEEE 802.15.4 standard, such as the impact of intensity nodes distribution,optimal guard zone, and outage probability. Simulation results show that the proposed power control design can reduce the outage probability and enhance energy efficiency. Energy efficiency and area spectral efficiency of the HCPP model are better than those of the PPP model. In addition, the optimal density of WBSNs coexistence is obtained.

Time-Variant Consensus Tracking Control for Networked Planar Multi-Agent Systems with Non-Holonomic Constraints

A time-variant consensus tracking control problem for networked planar multi-agent systems with non-holonomic constraints is investigated in this paper. In the time-variant consensus tracking problem, a leader agent is expected to track a desired reference input, simultaneously, follower agents are expected to maintain a time-variant formation. To solve the time-variant consensus tracking problem of planar multi-agent systems with non-holonomic constraints, a time-variant consensus tracking control strategy is designed on the basis of an unidirectional topology structure. One of main contributions of this paper is the time-variant consensus tracking protocol for general time-variant formations of planar multi-agent systems with non-holonomic constraints, the other main contribution of this paper is an active predictive control strategy, where predictions of agents are generated actively, so that the computational efficiency is improved than passive approaches. The proposed control strategy is verified by two types of time-varying formations of wheeled mobile robots, and the experimental results show that the proposed control strategy is effective for general time-variant consensus tracking problems of planar multi-agent systems with non-holonomic constraints in local and worldwide networked environments.

Simultaneous structure and luminescence property control of barium carbonate nanocrystals through small amount of lanthanide doping

Rare earth doping has been widely applied in many functional nanomaterials with desirable properties and functions,which would have a significant effect on the growth process of the materials.However,the controlling strategy is limited into high concentration of lanthanide doping,which produces concentration quenching of the lanthanide ion luminescence with an increase in the Ln^(3+)concentration,resulting in lowering the fluorescence quantum yield of lanthanide ion.Herein,for the first time,we demonstrate simultaneous control of the structures and luminescence properties of BaCO_3nanocrystals via a small amount of Tb^(3+)doping strategy.In fact,Tb^(3+)would partially occupy Ba^(2+)sites,resulting in the changes to the structures of the BaCO_3nanocrystals,which is primarily determined by charge modulation,including the contributions from the surfaces of crystal nuclei and building blocks.These structurally modified nanocrystals exhibit tunable luminescence properties,thus emerging as potential candidates for photonic devices such as light-emitting diodes and color displays.
