Accelerate Ageing

Natural substances have traditionally been used in skin care for centuries. There is now an ongoing search for new natural bioactives that not only promote skin health but also protect the skin against various harmful factors, including ultraviolet radiation and free radicals. Free radicals, by disrupting defence and restoration mechanisms, significantly contribute to skin damage and accelerate ageing. Natural compounds present in plants exhibit antioxidant properties and the ability to scavenge free radicals. The increased interest in plant chemistry is linked to the growing interest in plant materials as natural antioxidants. This review focuses on aromatic and medicinal plants as a source of antioxidant substances, such as polyphenols, tocopherols, carotenoids, ascorbic acid, and macromolecules (including polysaccharides and peptides) as well as components of essential oils, and their role in skin health and the ageing process.

Technology Transfer Process

An effi cient and effective information technology transfer from developed countries to Malaysia is an important issue as a prerequisite to support the ICT needs of the country to become not only a ICT user but also a ICT producer. One of the factors that infl uences successful information technology transfer is managing the process of how technology transfer occurs in one environment. It involves managing interaction between all parties concerned which requires an organized strategy and action toward accomplishing technology transfer objective in an integrated and effective mode. Using a conceptual framework based on the Actor Network Theory (ANT), this paper will analyse a successful information technology transfer process at a private company which is also a supplier of information technology (IT) products to the local market. This framework will explain how the company has come up with a successful technology transfer in a local environment. Our study shows that the company had given interest to its relationships with all the parties involved in the transfer process. The technology transfer programme and the strategy formulated take into account the characteristics of technology and all those involved.

Stress conditions in the elderly means an imbalance condition of biological, psychological, and social are closely related to the response to the threats and dangers faced by the elderly. Pressure or interference that is not fun is usually created when the elderly see a mismatch between the state and the 3 systems available resources. Maintenance actions that need to be done there are 2 types, namely : prevention of exposure to a stressor (precipitation factor) and serious treatment of the imbalance condition/ illness (precipitation factor). Prevention includes: sports, hobbies, friendship, avoid eating foods high in free radicals and harmful substances, sex and setting arrangements adequate rest. Habits of the above if done at a young age to avoid exposure to stress in the elderly. Treatment of the imbalance condition / illness, include : drinking water, meditation, eating fresh fruit, and adequate rest.
