IMPACTS OF DEFORESTATION ON MALARIA IN SOUTH WEST NIGERIA: THE EPIDEMIOLOGICAL‚ SOCIO-ECONOMIC AND ECOLOGICAL IMPLICATIONS Abstract Forest resources in Nigeria are undergoing severe exploitation pressure due to demographic growth and socio-economic development. Through the process of forest clearing‚ deforestation alters the ecology of local malaria vectors. The overall goal of this study was to seek to clarify the mechanisms linking deforestation‚ economic development and malaria epidemiology and

The History Of Vaccines And Immunization: Familiar Patterns‚ New Challenges Alexandra Minna Stern and Howard Markel Abstract Human beings have benefited from vaccines for more than two centuries. Yet the pathway to effective vaccines has been neither neat nor direct. This paper explores the history of vaccines and immunization‚ beginning with Edward Jenner’s creation of the world’s first vaccine for smallpox in the 1790s. We then demonstrate that many of the issues salient in Jenner’s era—such

Temperature range Background: All organisms are adapted to a particular environment with its characteristic temperature range. The temperature range allows the organism’s enzymes to control its metabolism by operating at their optimum efficiency within this range. Some organisms are adapted to live at high temperatures (80 - 100oC) and these are called thermophiles
