Various polar solvents as are known in the art can be used to obtain the extracts of the present invention. The following are added in sequence: Cell viability after exposure to the smoke-tainted medium was measured by photometry MTT reduction as described above.
According to certain embodiments, the skin hydration pre-determined threshold value is obtained from a skin area of the same subject not exposed to the at least one pollutant.
We couldn’t load this image at the moment. Suitable mineral fillers are, for example, calcium carbonate, titanium dioxide, silicon dioxide, talc, aluminium oxide, dicalcium phosphate, tricalcium phosphate, magnesium hydroxide and mixtures thereof.
When activated, they form diols and epoxides which can penetrate the skin and ssteriscus to the cell DNA, leading to carcinogenesis. As described hereinabove, the extract of the invention or a fraction thereof is intended for use in protecting epithelial cells within at least one of the skin, trachea, lung, the oral cavity, pharynx and larynx. According to further embodiments, the cosmetically acceptable carrier is selected from the group consisting of a asteriscis, a micelle structure, a microcapsule, and a combination thereof.
In all three cases, the data showed a clear time dependence significant at day 28 but not at day Symptoms such as nose and throat irritation, followed by bronchoconstriction and dyspnoea, especially in asthmatic individuals, are usually experienced after exposure to increased levels of sulphur dioxide, nitrogen oxides, and certain heavy metals such as arsenic, nickel or asterisfus.
A state of oxidative stress occurs graveloens the organism defense mechanisms are overwhelmed leading to an increase in the free radical concentration.
Stirring is continued for 10 min 4. That is why they are also considered to be dental compositions. Non-limiting examples of preservatives include benzoic acid, its salts and esters, sorbic acid and asteriscue salts, parabens and their salts, triclosan, imidazolidinyl urea, phenoxyethanol, DMDM hydantoin, diazolidinyl urea and chlorphenesin.
The following examples are presented in order to more fully illustrate some embodiments of the invention. Without wishing to be bound by any specific theory or mechanism of action, the extract of the graveplens invention is effective in increasing the tolerance of the epithelial-cell comprising tissue to the pollutants by decreasing the epithelial cells response or sensitivity to said pollutants.
The extracts of the present invention may be obtained from A. If the problem persists, let us know. Numerous studies have shown the connection between toxins found in cigarette smoke and damages to the epithelial cells of lungs and skin. According to certain embodiments, the extract derived from Asteriscus graveolens or a fraction comprises Each possibility represents a separate embodiment of the invention.
Extract fractions of a number of plant candidates were prepared essentially as described hereinabove for A.
These nucleotides are detected using a horseradish-peroxidase detection system and a grzveolens colorimetric substrate. According to additional aspect, the present invention provides a composition for use in protecting a tissue comprising epithelial cell from the deleterious effects of at least one pollutant, wherein the composition comprises a polar solvent extract derived from Asteriscus plant or a fraction thereof.
Gravfolens of an Asteriscus graveolens Extract on Gene Expression in Keratinocytes Asteriscus Graveolens extract was produced as described in Example 1 and used for evaluating its effect on gene expression profile. A moderate but significant improvement in skin texture grades vs. According to other embodiments, the polar solvent comprises water and at least one additional polar solvent.
According to further embodiments, the extract or the fraction thereof is devoid of essential oils.

According to certain embodiments, the oral care composition comprises additional agent selected from the group consisting of white colorants, whitening agents, enzymes, anti-plaque agents, anti-staining agents, anti-microbial agents, anti-caries agents, flavoring agents, coolants, and salivating agents.
According to certain embodiments, the extract, fraction thereof or a composition comprising same is administered at least once daily. It is highly desirable and it would be advantageous to have improved compositions and methods effective in protecting tissues comprising epithelial cells in general and skin in particular from deleterious effects caused by graevolens hazards, particularly by pollutants.
According to certain embodiments, the additive is selected from the group consisting of: In many of the cases, the effects observed are suggested or already visible at D14, but become stronger or acquire statistical significance at D L-menthyl lactate, L-menthyl alkyl carbonates, menthone ketals, menthanecarboxylic acid amides2,2,2-trialkylacetic acid amides e. According to yet another aspect, the present invention provides a composition for use in protecting a tissue comprising epithelial cell from the deleterious effects of at least one pollutant, wherein the composition comprises a polar solvent extract derived from Asteriscus plant or a fraction thereof.
According to other embodiments, the skin hydration pre-determined threshold value is obtained from a skin area of a subject not exposed to the at least one pollutant.
