40 results about "Senile plaques" patented technology

Senile plaques (also known as neuritic plaques) are extracellular deposits of amyloid beta in the grey matter of the brain. Degenerative neural structures and an abundance of microglia and astrocytes can be associated with senile plaque deposits. These deposits can also be a byproduct of senescence (ageing). However, large numbers of senile plaques and neurofibrillary tangles are characteristic features of Alzheimer's disease. Abnormal neurites in senile plaques are composed primarily of paired helical filaments, a component of neurofibrillary tangles. The plaques are variable in shape and size, but are on average 50 μm in size. In Alzheimer's disease they are primarily composed of amyloid beta peptides. These polypeptides tend to aggregate and are believed to be neurotoxic.

Topical Dermal Formulations and Methods of Personalized Treatment of Skin

Personalized skin-specific topical formulations containing conditioned medium obtained from cultures of fibroblasts has been developed. Unlike other topical formulations, these formulations are specific for the recipient-skin type specific, and conditioned medium is obtained from a subject with desired skin characteristics. For example, since African American skin is known to wrinkle less and later than Caucasian skin, conditioned medium may be obtained from African American skin for application to pale skin. In another embodiment, the fibroblasts are obtained from young skin for administration to older skin. In still another embodiment, the fibroblasts are obtained from skin that does not suffer from acne or discoloration, for application to skin that is prone to acne or discoloration. Examples of skin donor selection criteria include delayed wrinkling, small pores, resistance to sunburn, resistance to acne, uniform coloration or lack of blotching or age spots and good moisture retention.

Nano-structured thixotropic inorganic peeling gels

A composition, a method, and a kit are provided for chemical skin peeling, based on nano-structured thixotropic inorganic gels, which have a higher potency and are less irritant of the conventional peeling formulations. The gels of the invention can easily be applied on the skin, where they form a stable, uniform layer, that doesn't strain. The kit comprises by a defatting gel, different types of peeling gels and a neutralizing gel. The defatting gel is characterized by a markedly enhanced defatting capacity in comparison to the conventional products, because the sebum solubilized by the solvent is strongly adsorbed on the huge surface of the nano-structured material of the gel. The peeling gels are based on conventional peeling compounds, such as glycolic acid, trichloroacetic acid, pyruvic acid, salicylic acid, Jessner solution, but the presence of nano-structured material strongly increases the peeling effect, allowing the use of lower concentrations of peeling compound, with only minimal skin irritation for the user. The neutralizing gel is characterized by a colour change that allows the operator to verify in real time the neutralization of the peeling agent on the treated skin surface. All the gels of the invention can be easily removed from the skin after the treatment. The thixotropic gels of the invention can be used in chemical skin peeling for the treatment of various cosmetic conditions and dermatological disorders, including dry skin, acne, dandruff, keratoses, age spots, wrinkles and disturbed keratinisation.
