چکیده
The most common type of cataract – a nuclear cataract – is characterized by a cloudy haze inside the lens (Fig. 1). This haze is the physical manifestation of a random clumping together of the once beautifully ordered arrangement of lens proteins called crystallins. As the cataract develops in size and density, it reduces the amount of light that passes through the lens and scatters the light that does get through. Thus, instead of all the light rays being focused precisely to a point on the retina, forming a sharp, clear image of what we are seeing, many of the rays are spread out across the retina, forming a fuzzy image. Colors may be dulled or distorted, and there may be an annoying halo of light around bright objects, causing a glare effect.

The lens epithelium is especially vulnerable to oxidative stress. The erosion and shortening of telomeres in human lens epithelial cells in the lack of telomerase activity has been recognized as a primary cause of premature lens senescence phenotype that trigger human cataractogenesis.

BACKGROUND Innovative Vision Products, Inc. (IVP)'s scientists developed the lubricant eye drops (Can-C) designed as 1% N-acetylcarnosine (NAC) prodrug of L-carnosine containing a mucoadhesive cellulose-based compound combined with corneal absorption promoters in a sustained drug delivery system. Only the natural L-isomeric form of NAC raw material was specifically synthesized at the cGMP facil...

The antioxidant activity of L-carnosine (beta-alanyl-L-histidine, bioactivated in ocular tissues) versus N-acetylcarnosine (N-acetyl-beta-alanyl-L-histidine, ocular-targeted small dipeptide molecules) was studied in aqueous solution and in a lipid environment, employing liposomes as a model of lipid membranes. Reactive oxygen species (ROS) were generated by an iron/ascorbate promoter system for...

Background: Carnosine is a low molecular weight water soluble biological dipeptide, composed of alanine and histidine, present in a levorotatory form in mammalian tissues. Interesting activities are related to the detoxification from free radical species and byproducts of membrane lipids peroxidation. Objectives: The aim of the present study was to evaluate the photoprotective properties of car...
متن کاملBiological activities of the natural imidazole-containing peptidomimetics n-acetylcarnosine, carcinine and L-carnosine in ophthalmic and skin care products.
Apart from genetically programmed cell aging, different external aggressors related to oxidative stress and lipid peroxidation (LPO) can accelerate the skin aging phenomenon. Oxidative stress associated with the formation of lipid peroxides is suggested to contribute to pathological processes in aging and systemic diseases known as the risk factors for cataract. Despite the fact that L-carnosin...
