Optimization of Collagen Extraction from Fish Scales Using Tris-Glycine Buffer: A Taguchi Methodological Approach.

Collagen, a critical biomaterial with wide applications in pharmaceuticals, cosmetics, and medical industries, can be sourced sustainably from fish scales. This study optimizes the extraction of collagen using Tris-Glycine buffer from fish scales via the Taguchi method. Various extraction parameters-buffer concentration, temperature, pH, and time-were evaluated to identify optimal conditions.

Evaluating the effectiveness of laser hair reduction using a home use laser in comparison to a Diode laser.

Background: Lasers of different wavelengths have been developed for use in permanent hair reduction. An increase in the manufacturing of home-use laser hair removal devices allows for these treatments to be performed in the comfort of your own home at an affordable cost.

Objective: To evaluate the effectiveness of permanent hair reduction using a Diode laser in comparison to the Silk'n™ Flash and Go Lux (475-1200 nm) home-use laser.

Evaluation of the Occluding Characteristics of Nanosized Eggshell/Titanium Dioxide with or without Saliva.

Objectives:  The study reports on the effectiveness of a ball-milled nanosized titanium dioxide composite (EB@TiO) for DH management in comparison with commercial desensitizing paste with and without saliva.

Materials And Methods:   Forty-nine dentine specimens were prepared from extracted bovine anterior teeth. Twenty-one of the specimens were brushed with three desensitizing toothpaste for 7 days, namely: Group 1; EB@TiO, Group 2; Colgate Pro-relief; and Group 3; Sensodyne repair ( = 7).
