Leon Goldman (1904-1975)
Leon Goldman (1906 – December 2, 1997) was an American dermatologist and a pioneer in laser medicine.L. Goldman, Surgery by laser of malignant melanoma, ''J. Dermat. Surg. Onc.'' 5, 141-144 (1979).L. Goldman, A. Taylor, T. Putman, New development with the heavy metal vapor lasers for the dermatologist, ''J. Dermat. Surg. Onc.''13, 163-165 (1987). His research areas included the application of lasers in dermatology, cancer photodynamic therapy (PDT) and the use of organic dyes Juan de Guillebon, better known by his stage name DyE, is a French musician. He is known for the music video of the single "Fantasy (DyE song), Fantasy" from his first album ''Taki 183 (album), Taki 183''. This video became popular, attracting ... in PDT. In his honor, The American Society for Laser Medicine and Surgery (ASLMS) gives the yearly recognition named ''Leon Goldman Memorial Award''. The Academy of Laser Dentistry also gives an award in recognition of Dr. Goldman. It is called, "The Leon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laser Medicine
Laser medicine is the use of lasers in medical diagnosis, treatments, or therapies, such as laser photodynamic therapy, photorejuvenation, and laser surgery. The word ''laser'' stands for "light amplification by stimulated emission of radiation". History The laser was invented in 1960 by Theodore Maiman, and its potential uses in medicine were subsequently explored. Lasers benefit from three interesting characteristics: directivity (multiple directional functions), impulse (possibility of operating in very short pulses), and monochromaticity. Several medical applications were found for this new instrument. In 1961, just one year after the laser's invention, Dr. Charles J. Campbell successfully used a ruby laser to destroy an angiomatous retinal tumor with a single pulse. In 1963, Dr. Leon Goldman used the ruby laser to treat pigmented skin cells and reported on his findings. The argon-ionized laser (wavelength: 488–514 nm) has since become the preferred laser for ...

Photodynamic Therapy
Photodynamic therapy (PDT) is a form of phototherapy involving light and a photosensitizing chemical substance used in conjunction with molecular oxygen to elicit cell death ( phototoxicity). PDT is used in treating acne, wet age-related macular degeneration, psoriasis, and herpes. It is used to treat malignant cancers, including head and neck, lung, bladder and skin. Advantages lessen the need for delicate surgery and lengthy recuperation and minimal formation of scar tissue and disfigurement. A side effect is the associated photosensitisation of skin tissue. Basics PDT applications involve three components: a photosensitizer, a light source and tissue oxygen. The wavelength of the light source needs to be appropriate for exciting the photosensitizer to produce radicals and/or reactive oxygen species. These are free radicals (Type I) generated through electron abstraction or transfer from a substrate molecule and highly reactive state of oxygen known as singlet oxygen ( ...

Laser Dye
file:Coherent 899 dye laser.jpg, Close-up of a table-top dye laser using Rhodamine 6G as active medium. file:rhodamine 6G.svg, Molecular structure of Rhodamine 6G, perhaps the best known laser dye. A Laser dye is a dye used as laser medium in a dye laser. Laser dyes include the coumarins and the rhodamines. Coumarin dyes emit in the green region of the spectrum, whereas rhodamine dyes are used for emission in the yellow-red. The color emitted by the laser dyes depend upon the surrounding medium i.e.the medium in which they are dissolved. However, there are dozens of laser dyes that can be used to span continuously the emission spectrum from the near ultraviolet to the near infrared.F. J. Duarte, ''Tunable Laser Optics'' (Elsevier-Academic, New York, 2003) Appendix of Laser Dyes (includes more than 50 laser dyes) Laser dyes are also used to dope solid-state matrices, such as poly(methyl methacrylate) (PMMA), and Ormosil, ORMOSILs, to provide gain media for solid state dye las ...

Jewish Scientists
Jews (, , ), or the Jewish people, are an ethnoreligious group and nation, originating from the Israelites of ancient Israel and Judah. They also traditionally adhere to Judaism. Jewish ethnicity, religion, and community are highly interrelated, as Judaism is their ethnic religion, though it is not practiced by all ethnic Jews. Despite this, religious Jews regard converts to Judaism as members of the Jewish nation, pursuant to the long-standing conversion process. The Israelites emerged from the pre-existing Canaanite peoples to establish Israel and Judah in the Southern Levant during the Iron Age. John Day (2005), ''In Search of Pre-Exilic Israel'', Bloomsbury Publishing, pp. 47.5 8'In this sense, the emergence of ancient Israel is viewed not as the cause of the demise of Canaanite culture but as its upshot'. Originally, Jews referred to the inhabitants of the kingdom of JudahCf. Marcus Jastrow's ''Dictionary of the Targumim, Talmud Babli, Talmud Yerushalmi and Mi ...

University Of Cincinnati Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Middl ...
