• glial
  • The organization's most recent grade in 2007 assigned astroblastoma as a high-grade III and grade IV neoplasm, signifying that the glial tumor is dangerous for patients, causing fatal problems even after surgery. (wikipedia.org)
  • In general, when brain lesions are smaller than Grade I, demarcating between these features is near impossible, often mistaking astroblastoma with glial neoplasms, high-grade astrocytes, and embryonal neoplasms. (wikipedia.org)
  • organs
  • Interventional oncology has developed to a separate pillar of modern oncology and it employs X-ray, ultrasound, computed tomography (CT) or magnetic resonance imaging (MRI) to help guide miniaturized instruments (e.g. biopsy needles, ablation electrodes, intravascular catheters) to allow targeted and precise treatment of solid tumours (also known as neoplasms) located in various organs of the human body, including but not limited to the liver, kidneys, lungs, and bones. (wikipedia.org)
  • Concerns have been raised about injury to surrounding organs including bowel, bladder, ureters, pancreas, spleen and major vascular structures. (wikipedia.org)
  • structures
  • A substantial portion of the volume of the cytoplasm of smooth muscle cells are taken up by the molecules myosin and actin, which together have the capability to contract, and, through a chain of tensile structures, make the entire smooth muscle tissue contract with them. (wikipedia.org)
  • However, patients may require intervention during childhood, because 50% of IH leave residual fibrofatty tissue, redundant skin, or damaged structures after involution. (wikipedia.org)
  • retina
  • Iridectomy - Removal of the affected piece of the iris Choroidectomy - Removal of the choroid layer (the vascular tissue sandwiched between the sclera and the retina) Iridocyclectomy - Removal of the iris plus the ciliary body muscle. (wikipedia.org)
  • Retinoblastoma (Rb) is a rare form of cancer that rapidly develops from the immature cells of a retina, the light-detecting tissue of the eye. (wikipedia.org)
  • liver
  • Drugs or toxins that have a pharmacological (type A) hepatotoxicity are those that have predictable dose-response curves (higher concentrations cause more liver damage) and well characterized mechanisms of toxicity, such as directly damaging liver tissue or blocking a metabolic process. (wikipedia.org)
  • However
  • However, smooth muscle tissue tends to demonstrate greater elasticity and function within a larger length-tension curve than striated muscle. (wikipedia.org)
  • infection
  • These broad categories include cancerous processes or abnormal structure of bowel wall, inflammatory disease, colitis caused by infection or medications and vascular compromise. (wikipedia.org)
  • biological
  • The National Cancer Institute has set up a Bank for tissues and biological fluids from HIVpositive and HIV-negative individuals in order to have specimens available for scientists studying malignancies associated with HIV disease. (clinicaltrials.gov)
  • treatment
  • Today, modern radiation treatment modalities, as proton therapy, are likely to be chosen, for providing superior accuracy in dose delivery, helping to spare healthy tissue and the sensible optic nerves. (wikipedia.org)
  • This imprecise terminology has caused diagnostic confusion, blocked communication and even caused incorrect treatment, as it does not differentiate between various vascular anomalies. (wikipedia.org)
  • cause
  • Long-term issues may include parasitic growth of retained tissue with the potential to cause adhesions, cause bowel dysfunction and potentially disseminate unrecognized cancer. (wikipedia.org)
  • present
  • Interposed neural tissue is not present. (wikipedia.org)
  • Some vascular anomalies are congenital and therefore present at birth, others appear within weeks to years after birth and others are acquired by trauma or during pregnancy. (wikipedia.org)
  • appearance
  • The structure of this tissue is composed of septal (i.e. linear strands) and lobular compartments, which differ in microscopic appearance. (wikipedia.org)
  • layer
  • This tissue may be further divided into two components, the actual fatty layer, or panniculus adiposus, and a deeper vestigial layer of muscle, the panniculus carnosus. (wikipedia.org)
  • Removal
  • A morcellator is a surgical instrument used for division and removal of large masses of tissues during laparoscopic surgery. (wikipedia.org)
