Some studies are fairly extensive, for example, when conducted as part of a pharmaceutical drug development program. Others are short reports in the biochemical literature more than 20 years ago when the techniques for detecting protein degradation were not nearly as sophisticated as they are today.

Low temperature has been utilized to keep living cells and tissues dormant but potentially alive for cryopreservation and biobanking with great impacts on scientific and biomedical applications.

However, there is a critical contradiction between the purpose of the cryopreservation and experimental findings: the cryopreserved cells and tissues can be fatally damaged by the cryopreservation Author: Ali Erdem Öztürk, Mustafa Numan Bucak, Mustafa Bodu, Nuri Başpınar, İlhami Çelik, Zhiquan Shu, Nazan.

Studies on the freeze denaturation of fish muscle proteins were reviewed with emphasis given to changes in their physico-chemical and biochemical properties during frozen storage.

Denaturation of actomyosin commonly occurs during frozen storage and the side-to-side aggregation of myosin molecules appears to play a major role in this reaction. Herbs and spices have been used for both culinary and medicinal purposes for centuries.

Over the last decade, research into their role as contributors of dietary polyphenols, known to possess a number of properties associated with reducing the risk of developing chronic non-communicable diseases, has increased. However, bearing in mind how these foods are consumed, normally in small quantities Cited by: It is important for food materials to be delicious as well as nutritious and natural.

Rapidly increasing of human population of world, environmental pollution caused by consistently developing technology, insufficient education and problems caused by wrong nutrition are making supplying of natural food is more difficult.

Healthy nutrition refers to efficient and balanced nutrition, that is. Network pharmacology approach, integrating network biology and pharmacology, is introduced to study DM, which can combine the drugs, target proteins and disease and form drug-target-disease networks [1].

It has been widely used in the studies of the bioactive compounds and action mechanisms of natural products for the treatment of DM. Vitrification is therefore beginning to realize its potential for enabling the superior and convenient cryopreservation of most types of biological systems (including molecules, cells, tissues, organs, and even some whole organisms), and vitrification is even beginning to be recognized as a successful strategy of nature for surviving harsh Cited by: The use of dimethyl sulfoxide (Me2SO) as a cryoprotectant agent (CPA) is controversial.

Indeed, this cryoprotectant agent (CPA) is cytotoxic and potentially mutagenic. Therefore, other cryoprotectants must be used to reduce the proportion of Me2SO in slow-freezing solutions.
