For instance, China is estimated to take 48% of the world potential for CDM project activities. In reality, however, the share by China over the CDM projects registered and CDM projects in the pipeline is less than 10% as of Auguest 2005. This paper will examine the reasons behind, as reflected in China's CDM policies. Further investigation will be made into the use of these policies to boost the country's sustainable development, the sustainable development implications and effects of these policies. In addition, it is noted that incompatibility of some other Chinese laws and policies can be responsible for the low level and slow pace of CDM implementation in China and some suggestions are offered for promoting CDM project activities in China. There also exist barriers at the international level that impedes implementation of CDM project activities. A conclusion is drawn that CDM policies in a developing country like China aim mainly at promotion of sustainable development and to a lesser extent the generation of CERs.展开更多

With the increasingly aging population, AD has presented an overwhelming healthcare challenge to modern society; the World Alzheimer Report 2015 has estimated that 46.8 million people worldwide lived with dementia in 2015 and this number will rise to 74.7 million in 2030 and that the total cost of dementia was 818 billion in US$ in 2015 and will reach two trillion in 2030. Post-mortem studies have identified two histopathological hallmarks in the brains of AD patients; extracellular senile plaque with elevated deposition of amyloid β （Aβ） peptides, and intracellular neurofibrillary tangle composed of hyper-phosphorylated microtubule-associated protein tau.Etiologically, progressive neuronal loss within the cerebral cortex and hippocampus regions of the brain leads to irreversible decline in, and eventually complete loss of, memory and other cognitive functions that afflict AD patients. The widely-accepted amyloid cascade hypothesis for AD pathogenesis holds that accumulation and aggregation of neurotoxic Aβ peptides, due to imbalance of their generation and clearance as a result of changes in genetic makeup, aging and/or exposure to environmental risk factors, is a major and early trigger of AD. This hypothesis has continuously gained support by preclinical and clinical studies （Selkoe and Hardy, 2016）. However, the intensive and costly drug discovery efforts over the past decades based on such a hypothesis have proved extremely frustrating in developing effective therapeutics to treat or slow down the progress of AD, highlighting the need for more research to improve our understanding towards the cellular and molecular mechanisms by which Aβ peptides bring about neurotoxicity and cognitive dysfunction.展开更多
