A hot bed of organized dental leadership and visionary thinking in the mid-to-late 1800s came from Ohio, as many presidents of the American Dental Association were from that state. They were quite influential in leading this organization into the 20th century. One of the most dynamic and well-rounded individuals was Dr. George Watt…this paper will highlight his life as viewed by one of his peers.

James Watt (1736-1819) is remembered as a steam engine innovator and industrial magnate. A polymath, he was also a hands-on contributor to the Medical Pneumatic Institution of Thomas Beddoes. Watt recruited Humphry Davy, who there discovered analgesic action of inhaled nitrous oxide in 1799. Watt also built pneumatic equipment, and he introduced a gas mixture, dubbed hydro-carbonate, as a medical tonic. The bioactive component was carbon monoxide, a readily-lethal inhibitor of the transport and utilization of respiratory oxygen. Despite appreciable toxicity, carbon monoxide is an endogenous product of heme catabolism, and low doses of the gas are under laboratory investigation for therapeutic purposes. However, Watt's hydro-carbonate constituted a setback in the development of pharmacologically useful gases.

Review
The article processing charges associated with open-access publishing are unaffordable for some scientists. One solution is to break the APC down into its component parts, enabling scientists to spread the costs over multiple providers and several years. [Image: see text]

Comparative Study
Comparison of the efficiency, safety and pain scores of holmium laser devices working with 20 watt and 30 watt using in retrograde intrarenal surgery: One center prospective study.
OBJECTIVES
Holmium:Yttrium Aluminum Garnet laser lithotripsy is used in Retrograde Intrarenal Surgery. Fragmentation is made with a certain value of pulse energy (Joule) and frequency (Hertz) in Holmium laser lithotripsy and the multiplication of these values gives us total power (Watt). Devices with maximum power of 20 Watt and 30 Watt are used in clinical practice. We want to compare the efficiency, safety and pain scores of the lithotripsy made below 20 Watt and over 30 Watt with 30 Watt laser device.
MATERIALS AND METHODS
60 patients who had 2-3 cm sized kidney stones and operation planned were prospectively divided into three groups. Groups were random identified. In the first group, fragmentation was performed below 20 Watt power with 20 Watt laser device. In the second group, fragmentation was performed below 20 Watt power with 30 Watt laser device. In the third group, fragmentation was performed over 20 Watt power with 30 Watt laser device. Demographic, stone, intraoperative and postoperative data were recorded. We compared these groups regarding efficiency, safety and pain score.
RESULTS
For demographic and stone data, there was a statistically significant difference only for stone number. For intraoperative and postoperative data, there was a statistically significant difference only for ureteral access sheath usage between the groups. Success was lower than the other groups in Group 1.
CONCLUSIONS
Success was higher in groups using 30 Watt laser device. There was not statistically significantly difference between complications and pain. 30 Watt laser device is safe and efficient in Retrograde Intrarenal Surgery.

A watt-level ultrahigh optical signal-to-noise ratio single-longitudinal-mode (SLM) tunable Brillouin fiber laser (BFL) has been demonstrated. By optimizing the length of the single mode fiber (SMF) cavity at 11 m and its output ratio at 60%, 1.04 W output power, as well as stable SLM operation is obtained at 2.24 W pump power. The single pass cavity BFL has the advantage that the Brillouin pump frequency does not need to match the cavity mode, thus the stability is greatly improved. As only SMF is used in the cavity, the operating wavelength can be tunable without restriction from the self-lasing cavity mode. Furthermore, it proves that core-pumped single-frequency fiber laser is able to generate watt-level power. The laser demonstrates excellent performance in terms of noise, linewidth, and stability.
