The Impacts of Climate Change and Human Activities on the Structure and Function of Wetland/Grassland Ecosystems
Wetlands and grassland are important components of natural ecosystems, which have rich values in maintaining ecological balance, regional economy and human development. Wetlands can provide freshwater resources and food sources for human beings, purify the water environment and mitigate climate change. The grassland ecosystem has such ecological functions as windbreak, sand fixation, soil preservation, climate regulation, air purification, water conservation and so on, which are closely related to human survival and well-being. In recent years, climate change and human activities have caused a profound impact on the structure and function of wetland and grassland ecosystems, and the problems of decline in size and function have attracted extensive attention from researchers globally. However, there are still many uncertainties about the variety of wetland and grassland ecosystem composition, structure and dynamics, as well as how they respond and adapt to climate change and human activities.
Biochemical Basis and Therapeutic Implications of Angiogenesis
Angiogenesis is a highly complex phenomenon where new blood vessels are formed for the supply of oxygen and nutrients in different organs of the body. It plays a critical role in both physiological processes such as growth and development as well as pathological processes including cancer and different types of tumors. Angiogenesis is also essential for the regeneration and survival of cells in several disease conditions such as ischemic heart disease (myocardial infarction), atherosclerosis, brain injury (stroke) and diabetes. Since the mechanisms of angiogenesis are organ specific and differ among various diseases, it is proposed to devote one section of this book to the development of angiogenesis in some selected diseases such as cancer, ischemic heart disease, atherosclerosis, diabetes and stroke. It is pointed out that extensive research work in this regard has been carried out in the area of cancer and heart disease, whereas relatively less attention has been paid to studying angiogenesis in other disease conditions.
Life and Death in the Garden
This compelling book provides a rare glimpse into the heart of wartime China. Kathryn Meyer draws us into the perilous world of the Garden of Grand Vision, a ramshackle structure where a floating population of thousands found shelter from the freezing Siberian winter. They had come to the northern city of Harbin to find opportunity or to escape the turmoil of China in civil war. Instead they found despair. As the author vividly describes, corpses littered the halls waiting for the daily offal truck to cart the bodies away, vermin infested the walls, and relief came in the form of addiction. Yet the Garden also supported a vibrant informal economy. Rag pickers and thieves recycled everything ...
