7.340 Immune Evasion: How Sneaky Pathogens Avoid Host Surveillance (MIT)
Every infection consists of a battle between the invading pathogen and the resisting host. To be successful, a pathogen must escape the many defenses of the host immune system until it can replicate and spread to another host. A pathogen must prevent one of three stages of immune function: detection, activation, or effector function. Examples of disease-specific immune evasion and the mechanisms used by pathogens to prevail over their hosts' immune systems are discussed. Also considered is what

7.5 Summary of Section 7

  1. Site-directed mutagenesis is an important technique for studying protein function. Using recombinant DNA technology, selected amino acids can be substituted with different residues to alter the structure and function of a protein. One widely used method employs primer extension. SDM studies can help identify residues that are critical for interactions or catalytic activity.

  2. Protein–protein interactions can be studied in a number of different

2.5 Wavelength

So far we have seen that sound is a pressure wave, and that the spacing of the pressure variations is related to the period of vibration of the source.

A graphical representation of the pressure wave from a tuning fork closely approximates to a certain type of wave known as a sine wave.

If we freeze the pressure wave as a snap shot in time, the variations in pressure with distance from the tuning fork can be plotted as a sine wave. The vertical axis is pressure so the crest

1.1 Introduction

There are many environmental reasons why coal is a rather undesirable source of energy. Burning it introduces large amounts of gases into the atmosphere that harm the environment in a variety of ways, as well as other, solid waste products. Coal extraction leads to spoil heaps and mines that scar the landscape, land subsidence that affects roads and buildings, and in some cases water pollution.

With apparently so little going for it, why do we rely so much on coal to meet our energy nee

Introduction

An essential aspect of maintaining the body is the consumption of food. The range of foods that we eat is known as our diet and the components of food that are digested, absorbed and used in bodily functions are known as nutrients. Nutrients supply the body with both energy and with the components for growth and repair. In this free course, Obesity: balanced diets and treatment, you will examine the various roles of nutrients within the body and look at the effects of nut

7.342 Cancer Biology: From Basic Research to the Clinic (MIT)
This course is one of many Advanced Undergraduate Seminars offered by the Biology Department at MIT. These seminars are tailored for students with an interest in using primary research literature to discuss and learn about current biological research in a highly interactive setting. In 1971, President Nixon declared the "War on Cancer," but after three decades the war is still raging. How much progress have we made toward winning the war and what are we doing to improve the f

4.1 Global coal reserves

Having looked in detail at how coal is mined, this section focuses on those areas of the world that produce it. It begins by looking at how and why reserves of coal are distributed throughout the UK and Europe, before reviewing the current global reserves of coal.

2.3.2 Inner experiences

A second kind of data is people's inner experiences, including their feelings, beliefs and motives. These cannot be directly seen from the outside; they remain private unless freely spoken about or expressed in some other way. Examples of these inner experiences include feelings, thoughts, images, representations, dreams, fantasies, beliefs and motivations or reasons. These are only accessible to others via verbal or written reports or as inferred from behaviours such as non-verbal communicat

2 Discrimination in the labour market: introduction

Discrimination can manifest itself in all aspects of life. It may be evident in the type and location of housing available to certain groups, in their access to quality education and health care or how they are treated in the labour market. We will focus on the last of these considerations and, in particular, why the labour market status of some groups of workers is significantly worse than that for the population at large. This does not mean that discrimination in the labour market is a more

6.2 The hypothalamus as central regulator

Research in the past 30–40 years has established that the hypothalamus, which lies below the thalamus and above the optic nerve chiasma and the pituitary gland in the brain, fulfils all of the functions listed above, at least in part. The main function of the hypothalamus is homeostasis. Factors such as blood pressure, body temperature, fluid and electrolyte balance, and body weight are held to constant values called the set-points. Although set-points can vary over time, from day to

Understanding cancer: News from the frontline
This Oxford at Said seminar was dedicated to cancer research. Three researchers from the University of Oxford give insights into recent advances in the field of cancer cell biology, therapy and epidemiology. One in three people develop cancer, and one in five in Europe and North America die of the disease. Although environmental and lifestyle factors, for example smoking or sun exposure, affect the incidence of some cancer types, all human populations and many types of animal suffer from this di

HST.523J Cell-Matrix Mechanics (MIT)
Mechanical forces play a decisive role during development of tissues and organs, during remodeling following injury as well as in normal function. A stress field influences cell function primarily through deformation of the extracellular matrix to which cells are attached. Deformed cells express different biosynthetic activity relative to undeformed cells. The unit cell process paradigm combined with topics in connective tissue mechanics form the basis for discussions of several topics from cell
