and molecules act together in a dynamic network whose complexity rivals that of the nervous system. Functionally‚ an immune response can be divided into two related activities—recognition and response. Immune recognition is remarkable for its specificity. The immune system is able to recognize subtle chemical differences that distinguish one foreign pathogen from another. Furthermore‚ the system is able to discriminate between foreign molecules and the body’s own cells and proteins. Once a foreign

[10/23/12] Chapter 5 LEARNING * BEHAVIOR CHANGES THAT ARE DUE TO OUR EXPERIENCES OR THE ENVIRONENT * Simplest form of learning involves our senses * Simplest form learning = Habituation: Adjusting to stimuli that do not change. Example: You go into a guy’s room and smell something terrible‚ after a while you get used to the environment/smell and don’t even notice it. * Humans learn similarly to animals. Patterns of responding are similar to animals. * Types of Conditioning:

The information processing theory approach to the study of cognitive development evolved out of the American experimental tradition in psychology. Developmental psychologists who adopt the information-processing perspective account for mental development in terms of maturation changes in basic components of a child’s mind. The theory is based on the idea that humans process the information they receive‚ rather than merely responding to stimuli. This perspective equates the mind to a computer‚ which

Multiple Sclerosis Multiple Sclerosis (MS) is a chronic neurodegenerative disorder in the central nervous system that‚ effecting young adults‚ leading to non-traumatic disabilities. This disease starts as an auto-immune disease in which CD4 T cells cross the blood brain barrier and attack myelin sheaths of olygodendrocytes resulting in demyelination (Gandhi et al.‚ 2010; Lund et al.‚ 2013). Initially this is a transient process and re-myelination occurs‚ so initial stage of the disease is characterized

Ⅰ. Introduction It is widely acknowledged that people are an organization’s most important asset. The challenge for all leaders‚ however‚ is whether their behavior and attitudes towards their team reflect that belief. “In business‚ people should be treated as assets not costs. Assets help generate income and profits and so they are looked after and subject to ongoing investment. Costs‚ on the other hand‚ reduce profits and so should be kept to a minimum. Believing that people are assets means

Wanted to identify the simplest essential units of the mind and to determine how these units combine to produce complex mental phenomena. * Method: The study of conscious mental events and function of mental operations. The method was introspection. * Their contributions:

Discerning the Molecular Mechanisms of Entamoeba histolytica Erythrophagocytosis Abstract Entamoeba histolytica is a protozoan parasite representing a serious public health care crisis worldwide. It primarily affects people in low-income regions of impoverished nations and may affect the colon‚ liver‚ spleen‚ lungs‚ and brain. Erythrophagocytosis is a process that is vital to the pathogenicity of E. histolytica and therefore‚ the examination of molecular mechanisms involved

Viruses: A virus is a small infectious agent that replicates only inside the living cells of other organisms. A virus is a small parasite that cannot reproduce by itself. Once it infects a susceptible cell‚ however‚ a virus can direct the cell to produce many more viruses. Viruses can infect all types of life forms‚ such as animals and plants to microorganisms‚ including bacteria and archaea. Genetic materials of viruses: Most viruses have either RNA or DNA as their genetic material. The nucleic
