| sensorineural hearing loss | <neurology> A form of deafness that occurs due to dysfunction of the auditory nerve (cranial nerve VIII). (27 Sep 1997) |
| drift cyclotron loss cone instabilities | (DCLC) This is an electrostatic microinstability (frequencies at harmonics of the ion cyclotron frequency) which is of major concern in small mirror devices. Mode is driven by radial gradients in the electron density, and causes loss of ions due to non-conservation of magnetic moment (see adiabatic invariant) as they interact with the mode, and are dispersed in velocity space into the loss cone. Stabilisation is accomplished by increasing the plasma size and by partially filling the loss cone with a continuous extermal warm plasma stream. (09 Oct 1997) |
| eddy-current loss | <radiobiology> Energy loss due to eddy currents circulating in a resistive material. (09 Oct 1997) |
| tooth loss | The failure to retain teeth as a result of disease or injury. (12 Dec 1998) |
| functional visual loss | An apparent loss of visual acuity or visual field with no substantiating physical signs; often due to a natural concern about visual loss combined with suggestibility and a fear of the worst; best treated with reassurance. (05 Mar 2000) |
| loss cone | In a magnetic mirror machine, particles with a large velocity parallel to the magneitc field and a small velocity perpendicular to the field will be able to escape past the magnetic mirror (see magnetic mirror). In that case the velocity distribution function (see distribution function) will be almost zero in the region of velocity space that allows particles to escape. The shape of that region (in a velocity space diagram with parallel velocity and perpendicular velocity as the axes) is a cone. When a particle undergoes a collision, its velocity gets somewhat randomised. Particles that are scattered into that cone are lost very quickly (in one mirror bounce time). Thus it is called a loss cone. Because of the loss cone, the theoretical maximum particle confinement time of a magnetic mirror machine can be only a few times the particle collision time, this is generally seen as a showstopper for mirror-based fusion research.

| loss of consciousness | Total unresponsiveness. An important neurologic sign. (27 Sep 1997) |
| loss of heterozygosity | Refers to a mutation that results in the loss of allelic uniqueness, which is often defined as a greater than or equal to 40 percent increase in signal intensity of allelic signal. Loss of heterozygosity is most frequently identified in certain chromosome regions, including 5q, 17p, and 18q. (12 Dec 1998) |
| axillary hair | Hair of the armpit. (05 Mar 2000) |
| bamboo hair | Hair with regularly spaced nodules along the shaft caused by intermittent fractures with invagination of the distal hair into the proximal portion, with intervening lengths of normal hair, giving the appearance of bamboo; seen in Netherton's syndrome; autosomal recessive trait. Synonym: trichorrhexis invaginata. (05 Mar 2000) |

| bulb of hair | Hair bulb, the lower expanded extremity of the hair follicle that fits like a cap over the papilla pili. Synonym: bulbus pili, hair bulb. (05 Mar 2000) |
