Thermal effects produced in a laser-irradiated sample were studied by micro-X-ray diffraction and micro-Fourier transform infrared spectroscopy (FTIR). Gypsum, transformed into bassanite at 124 degrees C and into anhydrite at 147 degrees C, was used as a thermal indicator. Pit formation by a wavelength-tunable free electron laser (FEL) irradiation on the gypsum pellet maximized at a wavelength of ...<br/><br/>Toshiro Sakae, Yukie Sato, Yasuko Numata, Taketoshi Suwa, Tohru Hayakawa, Kunihiro Suzuki, Takao Kuwada, Ken Hayakawa, Yasushi Hayakawa, Toshinari Tanaka, Isamu Sato (2007) <i>Lasers Med Sci</i> <i></i> <i></i> 22: 1 15-20<br/>

PURPOSE: It is now well known that implant surface properties affect osseointegration. Grit-blasting with abrasives and coating by plasma are methods to modify implant surfaces. This study aimed to compare the direction of new bone formation associated with three types of surfaces. MATERIALS AND METHODS: Titanium (Ti) alloy rods grit-blasted with alumina abrasive (Group 1, G1), with apatitic abras...<br/><br/>Hiroshi Nakada, Toshiro Sakae, Racquel Z LeGeros, John P LeGeros, Taketoshi Suwa, Yasuko Numata, Kihei Kobayashi (2007) <i>Implant Dent</i> <i></i> <i></i> 16: 3 281-289<br/>

In the early mineralized enamel crystals, ribbon-like crystals appear near the ameloblasts. Some ribbon-like crystals showed helical or spiral structure within restricted environment during the preparation of embryonic bovine specimens for electron microscope. These specimens did not suffer from the cutting damages nor staining effects. The main cause of the helix structure is considered a result ...<br/><br/>K Suzuki, T Sakae, Y Kozawa (1998) <i>Connect Tissue Res</i> <i></i> <i></i> 38: 1-4 113-7; discussion 139-45<br/>

A new quick infrared spectroscopic method was developed and applied to analyze precipitates formed by cultured cells on a Petri dish. This IR method allows a dish to be placed directly on the sample beam window of a normal double beam IR spectrometer. Placing a blank dish on the reference beam window of the spectrometer compensates for the high background absorption due to the dish on the sample b...<br/><br/>T Sakae, J E Davies (1992) <i>J Biol Buccale</i> <i></i> <i></i> 20: 2 129-133<br/>

X-ray diffraction showed that crystals from the outer layer had larger crystallite sizes, a-axis length and peak intensities than the inner layer crystals. Upon heating, apatites in both layers showed a contraction of a-axis length and changed their crystallite sizes along the direction of the a-axis independently of changes along the c-axis.
