What's the difference between holmium and lutetium?
Holmium
Definition:
(n.) A rare element said to be contained in gadolinite.
Example Sentences:
(1) This experimental study was designed to define the potential value of a mid-infrared holmium laser in the free running mode for angioplasty.
(2) This article reviews holmium:YAG (yttrium-aluminum-garnet) laser physics, its tissue effects, and reports initial experience with its use in TMJ arthroscopy.
(3) This system is based on a thulium-holmium-chromium doped YAG (Tm-Ho-Cr: YAG) rod that lases at 2.15 micron.
(4) Six weeks after holmium laser angioplasty, SMC proliferation had returned to control levels in the intima and remained increased in the medial layer.
(5) We conclude that this lensed fiber coupled with a holmium:YAG laser is a safe and effective method for crossing total occlusions in the relatively straight iliac arteries of this animal model.
(6) The holmium laser has several advantages over excimer systems and may prove an effective adjunct or alternative to coronary balloon angioplasty.
(7) The aims were (1) To determine the histological and angiographic effects of holmium:YAG laser energy delivered through clinical multifibre laser catheters on fresh cadaveric coronary arteries; and (2) to relate the placement of optical fibres in the catheter to patterns of tissue ablation in cadaveric aorta.
(8) At a distance from the target tissue, excimer lasing resulted in no shock waves in saline, while the other lasers produced smaller shock waves than those recorded when the laser was in contact with tissue (0.22 versus 2.0 mm Hg with the pulsed dye laser, 0 versus 0.23 mm Hg with the excimer laser, and 0.44 versus 6.9 mm Hg with the holmium YAG laser; p less than 0.001, respectively).
(9) The aim of this study was to compare the tissue effect of three types of laser irradiation (Nd:YAG laser at 1.06 and 1.32 microns and holmium laser at 2.12 microns) on the rabbit endometrium.
(10) Chromium-sensitized and thulium- and holmium-doped YAG lasers (THC:YAG laser) were used to create a nasal bony ostium in the area of the lacrimal sac fossa in four fresh frozen bisected human cadaver heads.
(11) The holmium laser energy was coupled into nylon fibres.
(12) The coagulative necrosis zone for the 400 mJ holmium:YAG injuries measured from 370 microns to 640 microns, compared with 40 microns to 160 microns with the 250 mJ UV-excimer injuries.
(13) Using 200-microseconds pulses of 2.15-microns thulium-holmium-chromium:YAG (THC:YAG) laser light, we were able to create 700-microns-diameter holes through calcific atherosclerosis in vitro.
(14) Holmium-laser synovectomy was carried out to remove allergically inflamed synovial membranes in rabbit knee joints.
(15) The widest range of "ablation energy" (defined as that causing ablation without muscle damage) was achieved by applying the holmium laser.
(16) In an attempt to overcome some of the problems associated with combined cataract extraction and glaucoma filtration surgery, we attempted a new combined procedure: a small-incision phacoemulsification cataract removal with placement of a silicone foldable implant and no-stitch closure combined with a holmium laser sclerostomy in an adjacent quadrant, followed by injections of 5-fluorouracil.
(17) Shock waves were correlated with ablation efficiency (r = 0.63 and 0.74 for pulsed-dye laser and holmium-YAG laser, respectively).
(18) The crystal structure of the carbohydrate-recognition domain of a rat mannose-binding protein, determined as the holmium-substituted complex by multiwavelength anomalous dispersion (MAD) phasing, reveals an unusual fold consisting of two distinct regions, one of which contains extensive nonregular secondary structure stabilized by two holmium ions.
(19) Holmium:yttrium-aluminum-garnet laser thermocoagulation of the cystic duct can be performed easily, results in immediate cystic duct occlusion, and leads to permanent fibrous ductal obliteration by 6 weeks.
(20) Tissue reflectance as large as 50% was observed during holmium laser irradiation but depended upon laser radiant exposure and number of laser pulses.
