Initially associated with single-tumor, localized radiation therapy, the term has also come to encompass other types of localized treatments such as electroporation and intra-tumoral injection of therapeutics.Management of heart failure: Management of heart failure requires a multimodal approach. It involves a combination of lifestyle modifications, medications, and possibly the use of devices or surgery.Generalizability theory: Generalizability theory, or G Theory, is a statistical framework for conceptualizing, investigating, and designing reliable observations. It is used to determine the reliability (i.Coles PhillipsMetastatic liver disease: A liver metastasis is a malignant tumor in the liver that has spread from another organ affected by cancer. The liver is a common site for metastatic disease because of its rich, dual blood supply (the liver receives blood via the hepatic artery and portal vein).The Society of Elite Laparoscopic Surgeons: The Society of Elite Laparoscopic Surgeons is a non-profit organization based in Chandler, AZ, existing for the purpose of promoting access to minimally invasive surgery in the United States, and to lobby and promote the transition of the US medical system to adopt minimally invasive hysterectomy as standard of care.Society of Elite Laparoscopic Surgeons The organization is made up of member gynecologic surgeons, and holds annual meetings in various locales.Endoscopy unit: An endoscopy unit refers to a dedicated area where medical procedures are performed with endoscopes, which are cameras used to visualize structures within the body, such as the digestive tract and genitourinary system. Endoscopy units may be located within a hospital, incorporated within other medical care centres, or may be stand-alone in nature.ABCD rating: ABCD rating, also called the Jewett staging system or the Whitmore-Jewett staging system, is a staging system for prostate cancer that uses the letters A, B, C, and D.Age adjustment: In epidemiology and demography, age adjustment, also called age standardization, is a technique used to allow populations to be compared when the age profiles of the populations are quite different.ThoratecClonal Selection Algorithm: In artificial immune systems, Clonal selection algorithms are a class of algorithms inspired by the clonal selection theory of acquired immunity that explains how B and T lymphocytes improve their response to antigens over time called affinity maturation. These algorithms focus on the Darwinian attributes of the theory where selection is inspired by the affinity of antigen-antibody interactions, reproduction is inspired by cell division, and variation is inspired by somatic hypermutation.Panmixia: Panmixia (or panmixis) means random mating.King C and Stanfield W.Cryosurgery: Cryosurgery (cryotherapy) is the use of extreme cold in surgery to destroy abnormal or diseased tissue.DermNet NZ – Cryotherapy The term comes from the Greek words cryo (κρύο) ("icy cold") and surgery (cheirourgiki – χειρουργική) meaning "hand work" or "handiwork".Afterload: Afterload is the pressure in the wall of the left ventricle during ejection. In other words, it is the end load against which the heart contracts to eject blood.Branching order of bacterial phyla (Gupta, 2001): There are several models of the Branching order of bacterial phyla, one of these was proposed in 2001 by Gupta based on conserved indels or protein, termed "protein signatures", an alternative approach to molecular phylogeny. Some problematic exceptions and conflicts are present to these conserved indels, however, they are in agreement with several groupings of classes and phyla.Thrombolytic drug: Thrombolytic drugs are used in medicine to dissolve blood clots in a procedure termed thrombolysis. They limit the damage caused by the blockage or occlusion of a blood vessel.Multi-link suspension: __NOTOC__Robot-assisted double heart valve replacement: The first robotic-assisted double heart valve replacement was carried out in the Chennai region of India at Chettinad Hospital. Considered a rare form of surgery, this is the first instance of such a procedure using robotic surgery.National Clinical Guideline CentreJean Emond: Jean C. Emond is the current Thomas S.Clinical endpoint: In a clinical research trial, a clinical endpoint generally refers to occurrence of a disease, symptom, sign or laboratory abnormality that constitutes one of the target outcomes of the trial, but may also refer to any such disease or sign that strongly motivates the withdrawal of that individual or entity from the trial, then often termed humane (clinical) endpoint.Feasibility Study (The Outer Limits): "Feasibility Study" is an episode of The Outer Limits television show. It was first broadcast on 11 July 1997, during the third season.Balloon catheter: A balloon catheter is a type of "soft" catheter with an inflatable "balloon" at its tip which is used during a catheterization procedure to enlarge a narrow opening or passage within the body. The deflated balloon catheter is positioned, then inflated to perform the necessary procedure, and deflated again in order to be removed.HyperintensitySymmetry element: A symmetry element is a point of reference about which symmetry operations can take place. In particular, symmetry elements can be centers of inversion, axes of rotation and mirror planes.List of Parliamentary constituencies in Kent: The ceremonial county of Kent,Beta encoder: A beta encoder is an analog to digital conversion (A/D) system in which a real number in the unit interval is represented by a finite representation of a sequence in base beta, with beta being a real number between 1 and 2. Beta encoders are an alternative to traditional approaches to pulse code modulation.Assay sensitivity: Assay sensitivity is a property of a clinical trial defined as the ability of a trial to distinguish an effective treatment from a less effective or ineffective intervention. Without assay sensitivity, a trial is not internally valid and is not capable of comparing the efficacy of two interventions.Targeted therapy of lung cancer: Targeted therapy of lung cancer refers to using agents specifically designed to selectively target molecular pathways responsible for, or that substantially drive, the malignant phenotype of lung cancer cells, and as a consequence of this (relative) selectivity, cause fewer toxic effects on normal cells.Abdominal aortic aneurysmCancer biomarkers: A cancer biomarker refers to a substance or process that is indicative of the presence of cancer in the body. A biomarker may be a molecule secreted by a tumor or a specific response of the body to the presence of cancer.Lung cancer surgery: Lung cancer surgery describes the use of surgical operations in the treatment of lung cancer. It involves the surgical excision of cancer tissue from the lung.Fibrolamellar hepatocellular carcinomaDisease registry: Disease or patient registries are collections of secondary data related to patients with a specific diagnosis, condition, or procedure, and they play an important role in post marketing surveillance of pharmaceuticals. Registries are different from indexes in that they contain more extensive data.Phenotype microarray: The phenotype microarray approach is a technology for high-throughput phenotyping of cells.Atrial septal defectVentricular dyssynchrony: In cardiology, Ventricular dyssynchrony is a difference in the timing, or lack of synchrony, of contractions in different ventricles in the heart. Large differences in timing of contractions can reduce cardiac efficiency and is correlated with heart failure.ProstatectomyBiological ornament: A biological ornament is a secondary sexual characteristic of an animal that appears to serve a decorative function rather than an ostensible, utilitarian function. Ornaments are used in displays to attract mates in a process known as sexual selection.
