The smoothing or emoUient properties of creams and lotions are critical for making these emulsions the preferred vehicles for facial skin moisturizers, skin protectants, and rejuvenating products. On the body, emoUients provide smoothness and tend to reduce the sensation of tightness commonly associated with dryness and loss of Hpids from the skin. Although a wide variety of plant and animal extracts have been claimed to impart skin benefits, vaUd scientific evidence for efficacy has been provided only rarely. 

In order to provide a realistic approach to eutrophication control, the NRA has developed a framework for gathering the scientific evidence and for presenting the relevant information needed for consultation with all parties involved in resolving the problems. This framework includes the production of Action plans for each water on a case by case basis. The principal reason for using this approach is because the NRA is attempting to persuade external... 

Another notable glycoside is amygdalin, which occurs in bitter almonds and in the kernels or pits of cherries, peaches, and apricots. Hydrolysis of this substance and subsequent oxidation yields laetrile, which has been claimed by some to have anticancer properties. There is no scientific evidence for these claims, and the U.S. Food and Drug Administration has never approved laetrile for use in the United States. 

There is very little and in many instances no scientific evidence to justify the use of these plants as diuretics For example, dandelion root is a popular preparation once thought to be a strong diuretic. However, scientific research has found dandelion root safe but ineffective as a diuretic. No herbal diuretic should be taken unless approved by the primary care provider. 

A Health Guidance Value, set at a level at which there is no indication from the scientific evidence available that the substance is likely to be injurious to health. 

Nowadays food manufacturers, scientists and also consumers are interested in the health effects of foods. Therefore a lot of resources are being devoted to developing new food items with particular health effects for the market. However, in many cases scientific evidence authorising the health claims of such products is lacking. Phloem is one candidate as a functional food because... 

Overall, and contrary to others (Lyons, 1991), we feel that the weight of scientific evidence indicates that lipid peroxidation is increased in diabetes irrespective of whether complications are present or not. The presence of microangiopathy or severe atheroma is likely to increase the degree of peroxidation even further. 

Adequate sensitivity is required to measure an analyte accurately at the MRL (or tolerance) set by the regulatory agency. Tolerances and MRLs sometimes differ between agencies and may change as new scientific evidence indicates that the residue level... 

The accumulated scientific evidence of the relationships between coffee, caffeine, and serum cholesterol allows for several conclusions to be drawn, while some important issues remain either equivocal or unaddressed. The links involve a number of factors, including the chemical composition of coffee beans, its preparation method, the amount of daily consumption, and specific characteristics of coffee drinkers. Coffee contains hundreds of chemical compounds, caffeine being perhaps the best recognized and studied. Although caffeine has several well-established...

In this book I will share with you the process by which I came to this conclusion and the scientific evidence on which it is based. This includes evidence that was known to the pharmaceutical companies and to regulatory agencies, but that was intentionally withheld from prescribing physicians, their patients and even from the National Institute for Health and Clinical Excellence (NICE) when it was drawing up treatment guidelines for the National Health Service (NHS) in the UK. 

The conventional view of depression is that it is caused by a chemical imbalance in the brain. The basis for this idea was the belief that antidepressant drugs were effective treatments. Our analyses showing that most - if not all - of the effects of these medications are really placebo effects challenges this widespread view of depression. In Chapter 41 examine the chemical-imbalance theory. You may be surprised to leam that it is actually a rather controversial theory and that there is not much scientific evidence to support it. While writing this chapter I came to an even stronger conclusion. It is not just that there is not much supportive evidence rather, there is a ton of data indicating that the chem-... 

Much of what 1 write in this book will seem controversial, but it is all thoroughly grounded on scientific evidence - evidence that I describe in detail in this book. Furthermore, as controversial as my conclusions seem, there has been a growing acceptance of them. NICE has acknowledged the failure of antidepressant treatment to provide clinically meaningful benefits to most depressed patients the UK government has instituted plans for providing alternative treatments and neuroscientists have noted the inability of the chemical-imbalance theory to explain depression.6 We seem to be on the cusp of a revolution in the way we understand and treat depression. 

In response to increasing scientific evidence that human activities are contributing significantly to global climate change [1], decision makers are devoting considerable attention to public policies to reduce GHG emissions and thereby prevent or reduce such change.
