8 Enter aspirin!
What causes pain and how do we stop it? This unit looks at how the human body responds to the release of certain chemicals and as a result feels pain. Pain can be reduced by inhibiting the formation of such chemicals and you will learn how the molecular structure of aspirin has been formulated to help in this process.

Nucleic acids and chromatin
This unit helps you understand the properties of nucleotides and how they contribute to secondary and tertiary structures of nucleic acids at the molecular level. You will learn about the different composition and roles of nucleic acids in the cell, their interactions with each other and the use of ribozymes, aptamers, antisense and hybridization as tools in molecular research. The unit covers the function of DNA packaging within the cell, the interactions between the DNA double helix and the nu

4.1 Introduction
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.

7.340 Learning and Memory: Activity-Controlled Gene Expression in the Nervous System (MIT)
The mammalian brain easily outperforms any computer. It adapts and changes constantly. Most importantly, the brain enables us to continuously learn and remember. What are the molecular mechanisms that lead to learning and memory? What are the cellular roles that activity-regulated gene products play to implement changes in the brain?How do nerve cells, their connections (synapses), and brain circuits change over time to store information? We will discuss the molecular mechanisms of neuronal plas

3.4.2 Compaction and adhesion

Around the time of the 8- to 16-cell division, the conceptus undergoes a morphological (shape) change, called compaction, in which the cells fatten on each other, and the outlines of individual cells become hard to distinguish. This stage, sometimes referred to as a morula, from the Greek word for mulberry, is shown in Figure 17i. At this stage it is hard to see individual cells; in fact, unless the cells are separated by various laboratory treatments, it is not possible to see the two

Renal Pathophysiology
The importance of the kidneys is most clearly demonstrated in the presence of pathophysiologic states. The kidneys play a central role in the maintenance of the internal milieu by balancing fluid, electrolytes, and hydrogen ions to provide optimal conditions for molecular, cellular, and body system function. They also serve as the major excretory organ for metabolic byproducts, drugs, and other organic substances. Finally, the kidneys are an important endocrine organ, producing vasoactive factor
