A method of treating gum disease while healing the wound in the periodontium using a soft tissue diode laser which generates a beam of light having a wavelength in the visible portion of the electromagnetic spectrum (400 nm-700 nm) at a laser power of 0.001 to 1.2 watts, used with intermittent stops to control tissue temperature and biostimulate the periodontium to regenerate and heal its wound when used with substrates, the method comprising: placing the tip of the laser inside the sulcus; penetrating the entire sulcus by moving the laser light circumferentially around the tooth vertically and horizontally throughout the sulcus with intermittent stops to control tissue temperature and placing substrates in the sulcus prior to blood clot formation; followed by RF treatment of the sulcus by placing the RF headpiece tips perpendicular to the sulcus to receive RF current which further penetrates the wound site.

Disclosed herein are methods and compositions for delivery of polyribonucleotide. In some cases, the methods and compositions provided herein are suitable for in vivo delivery of polyribonucleotides. In certain aspects, also disclosed herein are cosmetic compositions for delivery of polyribonucleotide having cosmetic effects.

Stevia compositions are prepared from steviol glycosides of Stevia rebaudiana Bertoni. The compositions are able to provide a superior taste profile and can be used as sweetness enhancers, flavor enhancers and sweeteners in foods, beverages, cosmetics and pharmaceuticals.

The present invention relates to a composition for preventing or treating skin diseases, comprising a skin-penetrating nucleic acid complex as an effective component, and more specifically, to a pharmaceutical composition or a cosmetic composition for preventing, alleviating, or treating atopic dermatitis, comprising a skin-penetrating nucleic acid complex in which a carrier peptide nucleic acid and a bioactive nucleic acid targeting TLR2 or IL-4Rα are connected by complementary binding. The skin-penetrating nucleic acid complex according to the present invention, in which the carrier peptide nucleic acid and the bioactive nucleic acid targeting TLR2 or IL-4Rα are connected by complementary binding, has high skin permeation and skin retention, and thus is useful in the prevention, alleviation or treatment of skin diseases such as atopic dermatitis.

The present invention relates to an oral care product, such as a mouthwash, periodontal gel or a toothpaste comprising chlorhexidine and sodium DNA. Said oral care product presents an antibacterial effect effective against gingivitis, bacterial plaque and periodontitis combined with a healing and anti-inflammatory activity and which, moreover, counteracts the oxidative stress so as to limit the onset and the progression of irritations of the oral mucosae and promote their trophism.

Disclosed are a double stranded oligonucleotide construct, configured such that a hydrophilic material and a hydrophobic material are conjugated through a simple covalent bond or a linker-mediated covalent bond to both ends of a double stranded oligonucleotide in order to efficiently deliver an androgen-receptor-specific oligonucleotide into a cell, a nanoparticle capable of being produced by self-assembling double stranded oligonucleotide constructs in an aqueous solution through hydrophobic interactions, and a composition for preventing hair loss or promoting hair growth containing the double stranded oligonucleotide construct. The double stranded oligonucleotide construct including the androgen-receptor-specific oligonucleotide and the composition for preventing hair loss or promoting hair growth containing the same as an active ingredient can suppress the expression of an androgen receptor with high efficiency without side effects, and can thus exhibit excellent effects on preventing hair loss, particularly androgenetic alopecia, alopecia areata, and telogen effluvium, and promoting hair growth.

The present invention relates to a nanoliposome-microbubble conjugate, in which a complex of a Cas9 protein, a guide RNA inhibiting SRD5A2 gene expression and a cationic polymer is encapsulated in a nanoliposome, and to a composition for the amelioration or treatment of hair loss containing the same. Currently, drugs used for the treatment of hair loss cause serious side effects such as loss of libido or erectile dysfunction, and hair loss progresses again when drug treatment is stopped. However, when the nanoliposome-microbubble conjugate of the present invention is used, the expression of SRD5A2 inducing hair loss can be fundamentally suppressed, and the treatment of male hair loss can be performed very effectively.

An application of a transgenic stem cell-derived exosome in preparing a medicament or whitening cosmetic is provided. In the present disclosure, miR-27b-3p is transfected into an epidermal stem cell, and a transgenic stem cell-derived exosome is harvested. It is experimentally verified that the exosome can inhibit the expression of PIK3R3 protein in melanocytes and the proliferation and migration of melanocytes; and safety experiments further demonstrate the safety of the exosome. Therefore, corresponding medicaments or cosmetics prepared from the exosome have excellent medicinal and cosmetic application prospects.

A method of reducing oxidative damage of skin is described. The method can include applying to oxidant damaged skin a topical composition that includes encapsulated resveratrol, oligopeptide-1, and niacinamide, wherein the combination of encapsulated resveratrol, oligopeptide-1, and niacinamide reduces oxidative damage in the skin, and wherein the oligopeptide-1 comprises the sequence of caprooyl-Gly-His-Lys-Lys.

An adenosine-containing composition contains (A) adenosine, (B) at least one selected from the group consisting of salicylic acid and salts thereof, glycyrrhizic acid and salts thereof, and plant extracts, and (C) water. The amount of ethanol is less than 20% by mass relative to the mass of the adenosine-containing composition.
