Old and new theories of aging

There are several dozen theories of aging. Many of them are already only of historical interest, while the rest, reflecting a number of essential aspects of the process, can be put into a logical scheme of a more universal general mechanism of aging. One thing is common to all hypotheses – the aging of the body begins immediately after the division of the fertilized egg begins.

Activation of protomitochondria is the path to cell rejuvenation

A curious research project is under consideration at the Eternal Youth Foundation. The data obtained by the author as a result of previous studies supported by the RFBR grant allow us to count on the development of ways to treat mitochondrial encephalomyopathies and slow down and even prevent the aging processes of cells induced by damage to their active oxygen forms by activating the growth of protomitochondria, as well as the elimination of old mitochondrial organelles – postmitochondria.

Pharmaceutical industry: waiting for a deadlock

Competition from generic drugs (copies of original drugs) will lead to a reduction in sales of the largest American companies by $67 billion already in 2007-2012, as patent protection for more than 30 drugs will expire. This is almost half of the total revenue of US companies in 2007. Looking at all this, financial analysts do not recommend investing in the securities of pharmaceutical companies. Experts predict the leadership of biotechnologies, in which generics are technologically and legally impossible.

From flask to sausage

A small addition of substances present in any living cell – nicotinamide dinucleotide (NADH) and adenosine triphosphoric acid (ATP), as well as some harmless dicarboxylic acids – allow you to store ground sausage without spoilage for several weeks, and sausage instead of ten – forty, and not add poisonous nitrates and nitrites to them. But do industrialists accept safer technologies?

Biotechnology for Medicine (continued-1)

The use of natural diversity for therapeutic purposes is not limited only to fungi and actinomycetes that produce antibiotics.

Open, even more open…

Which way should a manager choose – to demonstrate closeness to subordinates or to introduce strict subordination? To what extent and in what way should the doors be "opened" in order to avoid the disadvantages and take advantage of the advantages of such a management style?

Vaccination against monopoly: the mechanism of registration of new vaccines is simplified

From the point of view of business, demonopolization and the involvement of additional state-authorized experts will only benefit, since it will allow more new immunobiological drugs to be brought to the end user faster. The new order is more convenient for everyone, except those who have lost their monopoly.

Biotechnology for medicine

The use of biotechnology of the potential of living organisms in the vital interests of man, his research and economic activities allows solving various problems.

Global pharmaceutical market: state and trends

Despite a slight slowdown in growth this year, the global pharmaceutical market is in excellent condition and on the verge of major changes.

Stem cells

"Stem" model of carcinogenesis

The common features of stem and cancer cells allowed us to call malignant ancestral cells cancer stem cells. These cells appear to be the result of a malfunction in the regulatory system of damaged stem cells or their direct descendants.

Is there a connection between the nature of stem cell division and the neoplastic process?

A potential cost for the frequent use of symmetrical stem cell division is an increase in the frequency of cancer that occurs during the transformation of somatic stem cells.
