A comparative study of the effect of ultrashort (0.5 ps) and short (15 ns) pulses on the laser forward transfer of DNA molecules is presented in this paper. We use femtosecond laser pulses to directly print a wide range of biomaterials, in complicated patterns and structures. The ultrashort laser pulses reduce the thermal effects, thus allowing the effective deposition of sensitive biomaterials...

OBJECTIVES Adult-to-adult living liver donation (LLD) is a controversial procedure due to the risk to the healthy donor. The decision to proceed with LLD is an important, yet under-researched area. This study aims to explore the decision-making process of the donor and recipient independently, and within the donor-recipient dyad. DESIGN A longitudinal, qualitative analysis of the LLD decision...

A compact and portable optofluidic microresonator has been fabricated and characterized. It is based on a Fabry-Perot microcavity consisting essentially of two tailored dichroic Bragg mirrors prepared by reactive magnetron sputtering deposition. The microresonator has been filled with an ethanol solution of Nile-Blue dye. Infrared laser emission has been measured with a pump threshold as low as...

1. INTRODUCTION The application of laser forward transfer techniques has steadily grown since the first reports of patterned copper deposition by Bohandy, et al. 20 years ago (Bohandy, 1986). These general techniques employ a pulsed laser to locally transfer material from a source film onto a substrate in close proximity or in contact with the film. The source is typically a coated laser-transp...

Tension band plating (TBF) has been pitted as the best method for correcting the angular deformities and limb length discrepancies (LLD) in growing children. In this review we examined the superiority of the tension band plating over other methods of growth modulation, in terms of safety and efficacy. As per the current literature, in angular deformities TBP has similar correction rates with le...

Supersonic Laser Deposition (SLD) is a coating and fabrication process combining cold spray (CS) with laser heating of the deposition zone. increases deformation on impact, improving bonding for given particle velocity, eliminating need to use helium while retaining advantages CS; solid-state deposition, low oxidation high build rate (≤ 10 kg/hr). Although solid lubricants offer over liquid lub...

Mechanical properties are important parameters that can be used to assess the physiologic conditions of biologic tissue. Measurements and mapping of tissue mechanical properties can aid in the diagnosis, characterisation and treatment of diseases. As a non-invasive, non-destructive and non-contact method, laser induced surface acoustic waves (SAWs) have potential to accurately characterise tiss...

Applications of shock wave research conducted in Tohoku University are briefly described. Its is emphasized that underwater shock wave research and its connection to bubble dynamics are one of the most important physical backgrounds to interpret tissue damages occurring during shock wave therapy. In addiction to ESWL, revascularization of cerebral thrombosis by using a laser induced liquid jet ...
