Endometrialablation is a medical procedure that is used to remove ablation ablate or destroy the endometrial lining of a woman s uterus . This technique is most often employed for women who suffer from excessive or prolonged bleeding during their menstrual cycle but can not or do not wish to undergo a hysterectomy . The procedure is most commonly done on an outpatient basis. Placenta accreta may occur if the patient becomes pregnant after endometrialablation, so birth control is recommended. Procedure A number of competing procedures are available. ref name pmid19821278 cite journal author Lethaby A, Hickey M, Garry R, Penninx J title Endometrial resection ablation techniques for heavy menstrual bleeding journal Cochrane Database Syst Rev volume issue 4 pages CD001501 year 2009 pmid 19821278 doi 10.1002 14651858.CD001501.pub3 ref The HTA System ref Hydro ThermAblator System HTA .

Annual loss of snow and ice through of ablation exceeds annual gain or accumulation of snow and ice in the ablation zone , zone of ablation , ablation area , or zone of wastage on a glacier . Processes of ablation include melting , evaporation , iceberg Ice calving calving , and Sublimation chemistry sublimation . Of these, melting is most important in most glaciers, but the others, especially iceberg calving, can be significant. Spatially, the zone of ablation lies below the snowline or firn line. The ablation zone often contains meltwater features such as supraglacial , englacial , and subglacial streams. The seasonally melting glacier deposits much sediment at its fringes in the ablation area. Ablation constitutes a key part of the glacier mass balance .

Cleanup date May 2007 Laser ablation is the process of removing material from a solid or occasionally liquid surface by irradiating it with a laser beam. At low laser flux , the material is heated by the absorbed laser energy and evaporation evaporates or Sublimation chemistry sublimates . At high laser flux, the material is typically converted to a Plasma physics plasma . Usually, laser ablation refers to removing material with a pulsed laser, but it is possible to ablate material with a continuous wave laser beam if the laser intensity is high enough. Fundamentals The depth over which the laser energy is absorbed, and thus the amount of material removed by a single laser pulse, depends on the material s optical properties and the laser wavelength . Laser pulses can vary over a very wide range of duration millisecond s to femtosecond s and fluxes, and can be precisely controlled. This makes laser ablation very valuable for both research and industrial applications. Applications The simplest application of laser ablation is to remove material from a solid surface in a controlled fashion.

Refimprove date January 2008 Autologous Endometrial Coculture is a technique of assisted reproductive technology . It involves placing a patient s fertilized eggs on top of a layer of cells from her own uterine lining, creating a more natural environment for embryo development and maximizing the chance for an in vitro fertilization IVF pregnancy. How Coculture is performed A typical Coculture cycle consists of the following steps br 1. Once a patient has been deemed an appropriate candidate for the procedure, she undergoes an endometrial biopsy during which a small piece of her uterine lining is removed. br 2. The uterine lining sample is sent to a research lab, where it is treated, purified and frozen. br 3. The patient then undergoes a typical IVF cycle and is given medication to stimulate egg growth in her ovaries . br 4. The patient s eggs are retrieved and mixed with the spermatozoon sperm . At this time, the lab begins thawing and growing her endometrial cells. br 5. Once fertilization is confirmed, the patient s embryo s are placed on top of her own and now thawed endometrial cells. br 6. Over the next two days, the embryos are closely monitored for growth and development. br 7. The patient s embryos are transferred into her uterus for implantation and pregnancy . The potential candidate Coculture can be an effective treatment for patients who have failed previous IVF cycles or who have poor embryo quality.

LASiS is usually considered a top down physical approach In the past years, laser ablation synthesis in solution LASiS emerged as a reliable alternative to traditional chemical reduction methods for obtaining noble metal nanoparticle s NMNp . LASiS is a green technique for the synthesis of stable NMNp in water or in organic solvents, which does not need stabilizing molecule s or other chemical s. The so obtained NMNp are highly available for further functionalization or can be used wherever unprotected metal nanoparticles are desired. Surface functionalization of NMNp can be monitored in real time by UV visible spectroscopy of the plasmon resonance . However LASiS has some limitations in the size control of NMNp, which can be overcome by chemical free laser treatments of NMNp.

Laser Ablation Electrospray Ionization LAESI is an ambient ionization method for mass spectrometry that combines laser ablation from a mid infrared mid IR laser with a secondary electrospray ionization ESI process. The mid IR laser is used to generate gas phase particles which are then ionized through interactions with charged droplets from the ESI source. LAESI was developed by Professor Akos Vertes and Dr. Peter Nemes in 2007 and is now marketed commercially by Protea Biosciences, Inc. LAESI is a novel ionization source for mass spectrometry MS that has been used to perform MS imaging of plants ..., if any ions, therefore an ESI source is located above the sample for post ablation ionization ref ..., A., Laser ablation electrospray ionization for atmospheric pressure, in vivo, and imaging mass ... of Live Tissue by Infrared Laser Ablation Electrospray Ionization Mass Spectrometry.
