A Comparative Study on the Effects of Vintage Nonpharmacological Techniques in Reducing Myopia (Bates eye exercise therapy vs. ).

Background: Human eye captures light rays as they come and fall on the retina and convert them into an image. However, in myopia, light rays fall in front of retina, causing blurring of image. Correction of this is generally done using correcting devices such as corrective glasses and contact lenses.

The synthesis, characterisation and in vivo study of a bioceramic for potential tissue regeneration applications.

Hydroxyapatite (HAP) is a biocompatible ceramic that is currently used in a number of current biomedical applications. Recently, nanometre scale forms of HAP have attracted considerable interest due to their close similarity to the inorganic mineral component of the bone matrix found in humans. In this study ultrafine nanometre scale HAP powders were prepared via a wet precipitation method under the influence of ultrasonic irradiation.

Thermal and ultrasonic influence in the formation of nanometer scale hydroxyapatite bio-ceramic.

Hydroxyapatite (HAP) is a widely used biocompatible ceramic in many biomedical applications and devices. Currently nanometer-scale forms of HAP are being intensely investigated due to their close similarity to the inorganic mineral component of the natural bone matrix. In this study nano-HAP was prepared via a wet precipitation method using Ca(NO(3))(2) and KH(2)PO(4) as the main reactants and NH(4)OH as the precipitator under ultrasonic irradiation.

Nanoengineering a biocompatible inorganic scaffold for skin wound healing.

Tissue engineering is a multidisciplinary field that can directly benefit from advancements in nanotechnology and nanoscience. This article reviews a representative selection of commercially available procedures and techniques used to treat different degrees of skin burns. It also explores the emerging novel biocompatible inorganic nano-engineered alumina membrane in terms of skin wound healing.

Effect of dilute gelatine on the ultrasonic thermally assisted synthesis of nano hydroxyapatite.

A series of nano hydroxyapatite-gelatine composites with different dilute solutions of gelatine concentrations were synthesized by a thermally assisted low-power ultrasonic irradiation method. The gelatine hydroxyapatite, (Gel-HAP) nanoparticles were prepared using Ca(NO(3))(2) and KH(2)PO(4) in the presence of gelatine in an aqueous solution. The synthesised products were heat treated between 100 and 400°C.
