With the elderly aging, the body's antioxidative defense system will have malfunction or failure, it can not produce a large number of antioxidants such as superoxide dismutase, catalase and glutathione peroxidase as before.
It is also subjected to an unprecedented oxidative damage caused by environmental factors of atmosphere, environmental pollution, processed foods and a huge pressure of life. All these will hurt the brain, eyes and other important body organs for elderly people.
Especially for the eyes, it experiences the unimaginable and more severe oxidative damage. Depletion of the ozone layer allows more than ever, blazing hot sun, directly affect the eyes and skin; excessive exposure to sunlight or in the highly oxidizing environment, a large number of free radicals will exist in our eyes. State called ischemia prevent eye nutrition and oxygen barrier, which is what lead to a common cause of eye oxidation upgrade; there is another reason ischemia barrier is cleared, the organization after the barrier is cleared to re-oxidation referred to as reperfusion, the consequence is that the eyes of the normal level of oxidative stress again imbalances. Even the normal enzymatic process will lead to free radicals and singlet oxygen, such as the increase of hydrogen peroxide, peroxides and hydroxides in the eye.
Oxidation of polyunsaturated fatty acids in the free radicals and singlet oxygen makes the retina to the detriment of the retinal cell membrane function, eventually leading to temporary or permanent damage of the retinal cells. Once retinal damage can not be repaired, and those antioxidants can penetrate the blood-brain barrier and blood-retinal barrier is critical, because they can protect the eyes against such damage.
As we all know, lutein and zeaxanthin will maintain eye health nutrients. Studies from cosmetic raw material suppliers and scientists confirm that they also help prevent old age-induced macular degeneration and other degradation. However, in view of the astaxanthin’s excellent antioxidant and anti-inflammatory effects, its benefits on eyes and brain health will far exceed all other nutrition and health products.
Eyes usually contain lutein and zeaxanthin, but not including the excellent A astaxanthin. Astaxanthin can cross the blood-brain barrier and blood-retinal barrier, rats eye astaxanthin content testing, and did not find the existence of the excellent A astaxanthin. Fed astaxanthin in rats re-testing, astaxanthin found in the retina. The experiments confirmed that astaxanthin can cross the blood-brain barrier into the brain, which in turn crosses the blood-retinal barrier in the brain reach the retina and the macula. A series of extensive testing to verify the astaxanthin pigment into the eyes will have more protection can prevent the harm.
Astaxanthin can prevent light damage, photoreceptor cell damage, ganglion cell damage, neuronal damage and inflammatory injury. Astaxanthin has a variety of anti-inflammatory properties. And it can protect the eyes through various channels to combat inflammation. Astaxanthin fights against with all kinds of problems through a variety of different forms. These diversity means are fast ways to health of the eye. They are safest and most natural.Source:http://www.cosprm.com
The application of tungsten in various industries
Steel Industry Most of tungsten applied in the production of special steels. The widely used high-speed steel was containing 9-24% of tungsten, 3.8-4.6% of chromium, 1-5% of vanadium, 4-7% of cobalt, 0.7-1.5% of carbon.
Magic effects of coconut oil
According to records, coconut oil can be regarded as the nobility of skin care plant extracts. It was rich in exotic tension of tropical plants, which can enhance the contractile force of the pores, perfectly beautify and nourish the skin.
The Evolution and Impact of Abamectin and Emamectin Benzoate in Pest Control
Abamectin and its derivative, emamectin benzoate, have emerged as pivotal substances in the realm of pest control, offering a broad-spectrum efficacy against various pests while maintaining a favorable environmental profile. As the agricultural industry continues to evolve, these compounds have adapted to meet the growing challenges of pest resistance, expanding their market applications and maintaining cost-effectiveness despite rising production costs.
