Ceramides in Healthy and Diseased Skin

Ceramides are the main polar lipids of the SC intercellular lipids; they play an important role in skin barrier function and account for half of the SC lipids by weight. Nine subclasses of ceramides have been described in human SC; these differ from each other by the sphingoid base groups (sphingosine, phytoshpingosine, 6-hydroxysphingosine) and hydrocarbon chain length. Ceramide content and changes of composition are involved in agingand skin diseases such as atopic dermatitis (AD),5–7 psoriasis, contact dermatitis (CD) and irritant dermatitis.

Cloned Pigs for Fatty Acids?

Researchers have cloned transgenic pigs that produce high levels of omega-3 polyunsaturated fatty acids.

A Dermatologic View: O/W Emulsions Enriched with Vitamin E

Vitamin E has an important protective function for the entire organism. It is believed that the broad biological activities of vitamin E are due to its ability to inhibit lipid peroxidation and stabilize biological membranes.

Consumers Getting Smarter about Health, Nutrition

As "baby boomers" turn 60 this year, it is apparent that consumers in the United States are not getting younger; however, they are getting smarter.

Monell Breakthrough Grows Mature Taste Receptors in the Lab

Researchers have succeeded in growing taste receptor cells outside of the body.

Neuropeptides in Antiaging?

Neuropeptides may be a new source for antiaging applications. According to a recent press release to the personal care industry, some physicians and clinicians say neuropeptides may revitalize skin and hair.

Biobank Project Initiated for Genetics, Disease Studies

Funded by the Wellcome Trust, the Medical Research Council, the Department of Health and the Scottish Executive, the study is designed to examine the interaction of genes, environment and disease in half a million people.

Identification of Differences in Stretch Mark-prone Individuals May Assist In Developing Novel Preventive Therapies

New data, published in the December 2005 issue of the Aesthetic Surgery Journal, suggests new potential for the development of therapies to predict, prevent and treat stretch marks.

Cationic Peptides and Cell Penetration

Controversy surrounds how certain cationic peptides enter the cell.

Nutritional Requirements of Mature Women Examined

Professor Ronni Chernoff examines the nutritional requirements of older women in, “Supplement: Women and Micronutrients: Addressing The Gap Throughout The Life Cycle.”

Stratum Corneum: The Role of Lipids and Ceramides

This paper reviews recent findings about the structure of the stratum corneum and the different models developed to better understand its function and behavior. The roles of intercellular lipids and ceramides as its key constituents are discussed.

Novel Approaches for Molecular Biology and Skin Care Products

The increasing demand for performance-driven personal care products and the need to understand a product’s mechanism of action provides a scientific challenge to the industry formulator, toxicologist and expert evaluator.
