Black Sea cucumbers (Holothuria atra) are a potential source of active metabolites such as flavonoids widely used for nutraceutical, pharmaceutical, and cosmeceutical products. The type nanoparticle that is often in cosmetics skin products Solid Lipid Nanoparticles (SLN). In this study, the SLN black sea cucumber extract will be prepared form peel-off gel mask an antioxidant. were extracted usi...

Solid lipid nanoparticle (SLNs) formulae were utilized for the release of 5-flurouracil (5-FU) inside the colonic medium for local treatment of colon cancer. SLNs were prepared by double emulsion-solvent evaporation technique (w/o/w) using triglyceride esters, Dynasan™ 114 or Dynasan™ 118 along with soyalecithin as the lipid parts. Different formulation parameters; including type of Dynasan, so...

Many aesthetic and functional problems of skin, such as cutaneous dryness and atopical dermatitis, are due to reduced amount of lipids in the external skin layer. These diseases can be resolved by using topical creams containing balanced mixtures of epidermal lipids. However, the set up of a suitable process for obtaining epidermal lipid based formulations represents a key step to yield an effe...

This study was to develop a novel method of nanoparticle-based MR colonography. Two types of solid lipid nanoparticles (SLNs) were synthesized with loading of (a) gadolinium (Gd) diethylenetriaminepenta acetic acid to construct Gd-SLNs as an MR T1 contrast agent and (b) otcadecylamine-fluorescein-isothiocyanate to construct Gd-fluorescein isothiocyanate (FITC)-SLNs for histologic confirmation o...

conclusions the results indicated that sod-loaded in sln was delivered into deep burned skin layer and induced high enzyme activity through the skin. low particle size, application of lecithin as surfactant and low crystallinity index (ci) percentage were important factors for increasing sod penetration through the burned rat skin. percentage of activity by sln dispersions through rat skin was ...

Carbendazim (MBC) (methyl-2-benzimidazole carbamate) and tebuconazole (TBZ) ((RS)-1-(4-chlorophenyl)-4,4-dimethyl-3-(1H-1,2,4-triazol-1-ylmethyl)pentan-3-ol) are widely used in agriculture for the prevention and control of fungal diseases. Solid lipid nanoparticles and polymeric nanocapsules are carrier systems that offer advantages including changes in the release profiles of bioactive compoun...

By excluding metals from synthesis, growth of carbon nanostructures via unreduced oxide nanoparticle catalysts offers wide technological potential. We report new observations of the mechanisms underlying chemical vapor deposition (CVD) growth of fibrous carbon nanostructures from zirconia nanoparticles. Transmission electron microscope (TEM) observation reveals distinct differences in morpholog...
