It is an exciting time for the discipline of cognitive
neuroscience. In the past 10 years we have
witnessed an explosion in the development and
advancement of methods that allow us to precisely
examine the neural mechanisms underlying cognitive
processes. Functional magnetic resonance
imaging, for example, has provided markedly improved
spatial and temporal resolution of brain
structure and function, which has led to answers to
new questions, and the reexamination of old questions.
The epidemiology of infectious diseases is one of the great triumphs of applied
ecology. In particular, the public health importance of parasites has
lead to a large literature, exploring their impact on the population dynamics,
population genetics and evolutionary biology of human populations. An
important milestone was the Dahlem Conference on population biology of infectious
diseases, held in 1981. The resulting book (Anderson and May 1982)
lucidly summarised the contemporary state of parasite ecology and epidemiology.
The global cost of communicable diseases is expected to rise. SARS has
put the world on alert. We have now Avian Flu on the watch. Recognizing
the global nature of threats posed by new and re-emerging infectious diseases
and the fact that many recent occurrences originated in the Asia Pacific
regions, there has been an increased interest in learning and knowing
about disease surveillance and monitoring progresses made in these regions.
Such knowledge and awareness is necessary to reduce conflict, discomfort,
tension and uneasiness in future negotiations and global cooperation....
The cones function under daylight (photopic) conditions. The cone system is specialized for color perception and high spatial resolution. The majority of cones are located within the macula, the portion of the retina serving the central 10° of vision. In the middle of the macula a small pit termed the fovea, packed exclusively with cones, provides best visual acuity. Photoreceptors hyperpolarize in response to light, activating bipolar, amacrine, and horizontal cells in the inner nuclear layer. ...
One of the main advantages of this technique is that it can produce the scaffold with main
structural feature suitable for growth of the cell and subsequent tissue organization (Li &
Tuan, 2009; Liang et al., 2007; Leong et al., 2008). It can produce the ultra fine fibers with
special orientation, high aspect ratio, high surface area, and having control over pore
