| hair loss | Hair loss may be associated with aging, hormones (androgens) or genetic predisposition. The pattern of baldness in women is different from that of men. In women there is thinning of the hair all over the scalp, but the frontal hairline is maintained. The hair loss is usually permanent. Treatment has been successful with topical minoxidil in some cases. (13 Nov 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) |

| alexander disease | <radiology> Dysmyelinating disease, rare, sporadic, usually presents in 1st year, gradual enlargement of head (Differential diagnosis: Canavan disease), retardation, convulsion, spasticity CT findings: decreased density of white matter, frontal lobe predominance, with or without dilated lateral ventricles Diagnosis: brain biopsy (12 Dec 1998) |
| Alexander Fleming | <person> This native of Scotland studied medicine at St. Mary's Hospital Medical School in London, where he won almost every prize and scholarship prize available. He graduated with honors in 1908 and 20 years later became Professor of Bacteriology at his alma mater. During World War I, he devoted his interest to problems of infection and developed an antiseptic proteolytic substance, lysozyme (muramidase). He managed a vaccine for acne, and developed a miniature technique for the Wassermann (syphilis) reaction. Although the Belgians, Gratin and Path, in 1925 reported a mould, Streptothrix, which inhibited the growth of staphylococcus, Alexander Fleming was the first to prove such in 1928. Fleming found the mould Penicillium notatum, listed the organisms sensitive to it, emphasised that it was not toxic to leukocytes, and used it on surface wounds 12 years before it became commercially available. Fleming's description of his discovery is interesting - "I opened a culture plate of staphylococci and something fell from the air onto the plate. Later I saw lysis of the staphylococci colony. Instead of casting out the contaminated culture with "appropriate language," I made some investigations. My lab was dingy and dim coloured. If this had been an American lab, this could never have been discovered." He shared the Nobel Prize for Medicine in 1945 with Florey and Chain, who extracted penicillin from the mould and commercially produced it. Lived: 1881-1955. (15 Nov 1997) |
| Alexander, Gustav | <person> Austrian otolaryngologist, *1873. See: Alexander's deafness. (05 Mar 2000) |
| Alexander of Tralles | <person> Alexander was the youngest of five famous brothers and he too was a famous physician in his day and once practiced in Rome, where he has been introduced lately as one of the greatest scholars from the time of Galen to the Renaissance. He is chiefly remembered as the Father of Helminthology (study of parasitic worms). He accurately differentiated the Oxyuria, a species of intestinal worms which he treated with enemas of ethereal oil. He treated lesions of the upper bowel orally, and lesions of the lower bowel by the anus. He also introduced wine of colchicum for the treatment of gout, and this drug has remained as a current treatment. Alexander's pharmacy texts were required reading five centuries later at the University of Paris. His greatest book was 12 Books on Medicine. Lived: 525-605. (15 Nov 1997) |
