A material for adhesion prevention can be adhered to biological tissue with certainty and has improved tissue adhesiveness and biodegradability. Such material for adhesion prevention is composed of: a 1- to 1,000-&#x3bc;m-thick water-soluble support layer comprising a water-soluble polymer; and a 1- to 1,000-&#x3bc;m-thick adhesion prevention layer comprising a biodegradable polymer. The biodegradable polymer has a structure in which a branched polyalkylene glycol comprising 3 to 8 terminal hydroxyl groups per molecule is bound to a polyhydroxy alkanoic acid, and a mass ratio of the branched polyalkylene glycol relative to the total mass is 1% to 30%.

A laminated film includes a polylactic acid-based resin layer and one or more acetylated hyaluronic acid layers laminated on a side of the polylactic acid-based resin layer, is highly flexible and easy to handle and, when stuck to an adherend with curved surface, the laminated film has excellent followability, adhesiveness and coating properties to the adherend, since the acetylated hyaluronic acid layer(s) can be removed easily with an aqueous solution from the polylactic acid-based resin layer in a thin film shape. The acetylated hyaluronic acid and the polylactic acid-based resin are biodegradable and, therefore, the laminated film is highly compatible with skin and organs such as visceral organs. The laminated film is optimally usable as a dermal material for external application such as a wound coating material, an adhesion inhibitor and skin care articles.

An derivation method of a nail apparatus melanoma discrimination threshold includes a first step of assuming a color image of longitudinal melanonychia as three-dimensional vectors each composed of RGB parameter values of each pixel and finding an angle between each of the three-dimensional vectors and a reference vector, a second step of finding a probability of occurrence according to a frequency distribution of the angles found in the first step, and a third step of finding, according to the probability of occurrence found in the second step, a threshold for a parameter to discriminate whether the longitudinal melanonychia is malignant or benign.

The present invention provides pH-responsive liposomes which are capable of holding a desired substance in an acidic pH environment and releasing the desired substance in a basic pH environment. The present invention uses pH-responsive liposomes comprising, as constituent lipids thereof, a cationic amphiphilic molecule and at least one of an anionic amphiphilic molecule and a twitterionic amphiphilic molecule, wherein the liposomes, when dispersed in an aqueous medium, have a positive zeta potential in an acidic environment where the dispersion has a pH of less than 6.5 and have a negative zeta potential in a basic environment where the dispersion has a pH of 8.5 or more.

A device having a shape capable of receiving the plant body to be cultivated. As at least a portion of the device, a film which can substantially be integrated with the root of the plant body is disposed. Such a structure can provide a plant-cultivating device, a plant-film integrate, and a plant-cultivating method which can preferably attain both of the supply of oxygen and the supply of water and a fertilizer component to the root of the plant body.
