Non-programmed aging theories suggest that in general symptoms of aging are independent of each other. We can find treatments for highly age-related conditions like cancer, different treatments for heart disease, yet different treatments for Alzheimer’s, and so forth, but aging is itself an untreatable condition. “Anti-aging medicine” is confined to cosmetically delaying the appearance of aging...

will have noticed a number of cosmetic changes made to the journal since it received its last major facelift at the beginning of 1999. Most of these changes have been designed to make the journal a more attractive “read”. But the real changes go more than skin deep. The Editorial Board has been implementing structural changes to the way that the journal is produced and disseminated, with the ai...

BACKGROUND Statistics published by The American Society for Aesthetic Plastic Surgery report a 48% increase in cosmetic procedures for 2000-2001 and a 14% increase for rhytidectomies alone. Patients aged 35 to 50 account for 30.2% of all rhytidectomies performed. Many of these patients undergo secondary rhytidectomy. OBJECTIVE We investigated differences between patients undergoing secondary ...

We describe a scenario of independent TV programme dissemination where viewers receive their own tailored channel created from content in which they’re interested. We focus primarily on the problem of distributing the content from the producers to all interested viewers. Our approach is based on a multicast scheme called implicit group messaging, realised as a distributed structured peer-to-pee...

The author provides advice on face lift incision placement to preserve ear contour and maintain normal sideburn position.

Background and experimental approach A main challenge in cell therapies and other tissue regeneration approaches is to produce a therapeutically significant cell number. For expansion of mesenchymal stem cells (MSC) the cultivation on 2D plastic surfaces is still the conventional procedure, even though the culture conditions differ significantly from the 3D environment in vivo. Additionally, st...

Introduction The purpose of a seed train is the generation of an adequate number of cells for the inoculation of a production bioreactor. This is timeand cost-intensive: From volumes used for cell thawing or cell line maintenance the cell number has to be increased. The cells are usually run through many cultivation systems which become larger with each passage (e.g. T-flasks, roller bottles or...

Although bioreactor landfills have many advantages associated with them, challenges remain, including the persistence of ammonia-nitrogen in the leachate. It has been suggested that ammonia-nitrogen is one of the most significant long-term pollution problem in landfills and is likely a parameter that will determine when landfill postclosure monitoring may end. The fate of nitrogen in bioreactor...
