人口问题是指人口发展与社会经济发展不相适应,与环境、资源不相协调,人口与自然、人口与社会矛盾激化而产生的影响人类生存和发展的各种问题的总称。环境问题是人类向环境索取资源的速度超过资源本身及替代品的再生速度,或者向环境... 人口问题是指人口发展与社会经济发展不相适应,与环境、资源不相协调,人口与自然、人口与社会矛盾激化而产生的影响人类生存和发展的各种问题的总称。环境问题是人类向环境索取资源的速度超过资源本身及替代品的再生速度,或者向环境排放废弃物的数量超过了环境的自净能力所产生的。人口、环境是人类社会的最基本要素,两者关系密不可分。环境是人类赖以生存的基础,随着人类社会的进步、生产力的发展,人类适应环境的能力比过去大大增加,但人口数量的变化,素质的提高及人口迁移和分布的改变,仍然受环境条件的制约。人口、环境问题已经成为全球共同关注的热点问题。 展开更多

Choosing a strategy for sustainable development is national level aimed at the simultaneous fulfillment of economic, a fundamental problem that requires non-trivial approaches at the social and environmental goals. This contradiction is possible to be adequately described in the complex game-theoretic models. But analysis of them is complicated by the problems of algorithmic solvability and the payoff functions construction. Also, the volume of data required creates considerable complexity increased by the conditions of situations uncertainty and conflict. At the same time, international organizations, such as UN (United Nations), ITU (International Telecommunications Union), are widely used index system. Indices, built on the aggregation of elementary indicators, allow the estimation of the components of the system and its overall development. The paper discusses the basic concepts of game-theoretic approach to the problems of finding strategies for sustainable development, using indicative analysis techniques. In the proposed approach, estimating of sustainability is considered as the result of finding the optimal values of the payoff functions in general game-theoretical model where the players are matched indices. The interests of the player are to increase of the corresponding index and the optimal situation is implemented as a set of optimal payoff functions values. This allows switching from processing of large amounts of data describing the behavior of the ecological-economic system by the aid of indicators to aggregate estimations, which significantly reduce the sample, and also facilitates the interpretation of the results. 展开更多

Objective: Cancer-associated fibroblasts (CAFs) are one of the hallmarks of the cancer microenvironment. Recent evidence has indicated that CAFs are more competent in enhancing cancer cell growth and migration than normal fibroblasts. However, the unique protein expression of CAFs has not been fully elucidated. This study aims to investigate the characterizations of colon CAFs by comparing the differential protein expression between CAFs and normal fibroblasts. Methods: Primary fibroblasts were isolated from surgical specimen of human colon cancer and matched normal colonic tissue. Purity of the cell population was verified through immunostain analysis. Total cell lysates and conditioned media from each group of cells were extracted, and protein expression analysis was con- ducted using the surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (SELDI-TOF-MS) ProteinChip platform. Results: Most primary cells showed typical fibroblast-like features after two weeks. Increased proportion of a-smooth muscle actin-positive myofibroblasts was detected within the CAFs in four of the six pairs of primary cells. Fibroblast activation protein was weakly expressed in most cells without differences. Using SELDI-TOF-MS ProteinChip platform, four protein peaks mass over charge ratio (m/z) 1142, 3011, 4035, and 4945 were detected in the total cell lysates, and two protein peaks m/z 1368 and 1389 were detected in the conditioned media. The potential candidate proteins found in the Swiss-Prot database include morphogenetic neuropeptides, FMRFamide-related peptides, insulin-like growth factor II, thymosin 13-4-like protein 3, and tight junction-associated protein 1. Conclusions: Using the SELDI-ProteinChip platform, differential protein expressions were identified in colon CAFs compared with normal colonic stromal fibroblasts. The complex proteomic alternations in colon CAFs may play important roles related to the colon cancer microenvironment. 展开更多
