Signs and symptoms of higher cortical dysfunction caused by organic conditions. These include certain behavioral alterations and impairments of skills involved in the acquisition, processing, and utilization of knowledge or information.
Filament or fiber, or the materials generated from them by weaving, embroidery, knitting, crocheting, tufting, or felting such as yarn, thread, cording, rope, netting, lace, or sheets of cloth or fabric.
Classes of retroviruses for which monkeys or apes are hosts. Those isolated from the West African green monkey and the Asian rhesus macaque monkey are of particular interest because of their similarities to viruses causing cancer and acquired immunodeficiency syndrome (AIDS) in humans.
A method of computed tomography that uses radionuclides which emit a single photon of a given energy. The camera is rotated 180 or 360 degrees around the patient to capture images at multiple positions along the arc. The computer is then used to reconstruct the transaxial, sagittal, and coronal images from the 3-dimensional distribution of radionuclides in the organ. The advantages of SPECT are that it can be used to observe biochemical and physiological processes as well as size and volume of the organ. The disadvantage is that, unlike positron-emission tomography where the positron-electron annihilation results in the emission of 2 photons at 180 degrees from each other, SPECT requires physical collimation to line up the photons, which results in the loss of many available photons and hence degrades the image.
A treatment program based on manipulation of the patient's environment by the medical staff. The patient does not participate in planning the treatment regimen.
A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principal cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX. --consider also terms at OSSI- OSTE-
