| topping and back pressure turbine | Turbines which operate at exhaust pressure considerably higher than atmospheric (noncondensing turbines). These turbines are often multistage types with relatively high efficiency. (05 Dec 1998) |
| true muscles of back | Muscles of the back innervated by the dorsal primary rami of spinal nerves; includes erector spinae, transversospinalis, interspinal, and intertransverse muscles; excludes the superficial back muscles which are appendicular and are innervated by ventral rami, and the trapezius, innervated by the spinal accessory nerve. Synonym: true muscles of back. (05 Mar 2000) |
| fold-back elements | A type of transposable element that possesses long inverted repeats, such that when denatured, loops are formed. (05 Mar 2000) |
| low back pain | A continuous pain in the lower back or lumbar region. (12 Dec 1998) |
| anterior focal point | The point where parallel rays from the retina are focused. (05 Mar 2000) |
| Berger's focal glomerulonephritis | Glomerulonephritis affecting a small proportion of renal glomeruli which commonly presents with haematuria and may be associated with acute upper respiratory infection in young males, not usually due to streptococci; associated with IgA deposits in the glomerular mesangium and may also be associated with systemic disease, as in Henoch-Schonlein purpura. Synonym: Berger's disease, Berger's focal glomerulonephritis, focal nephritis, IgA nephropathy. (05 Mar 2000) |
| glomerulosclerosis, focal | Glomerular disease characterised by focal and segmental areas of glomerular sclerosis, usually commencing in the juxtamedullary glomeruli and gradually spreading to involve other parts of the kidney, with eventual kidney failure. (12 Dec 1998) |
| chronic focal sclerosing osteomyelitis | A reaction of bone to a mild bacterial infection, often the result of a carious tooth, in persons with a high degree of tissue resistance; results in a localised radio-opacity. Synonym: focal condensing osteitis. (05 Mar 2000) |
| positive focal length | <microscopy> Any lens which converges parallel rays to a focus at the back of the lens is a positive lens and has a positive focal length. The focal length is measured from the second principal point of the lens to the point on the lens axis where the rays from an infinitely distant point are brought to focus. See: negative focal length. (05 Aug 1998) |
| posterior focal point | The point of a compound optical system where parallel rays entering the system are focused. (05 Mar 2000) |
| cutaneous focal mucinosis | Flesh-coloured papules of the skin, composed of homogenous mucinous material with scattered fibroblasts. (05 Mar 2000) |
| proximal femoral focal deficiency | A congenital defect in which variable portions of the upper end of the femur are reduced or absent. (05 Mar 2000) |
| negative focal length | <physics> The focal length of a negative lens. Parallel rays impinging on a negative lens can be traced to a virtual focus which exists on the same side of the lens as the impinging rays. The distance from the second principal point of the lens to this second focal point is measured on the same side of the lens as is the object. See: negative lens, focal length. (05 Aug 1998) |
| dystonia, focal, due to blepharospasm | The second most common focal dystonia, the involuntary, forcible closure of the eyelids. The first symptoms may be uncontrollable blinking. Only one eye may be affected initially, but eventually both eyes are usually involved. The spasms may leave the eyelids completely closed causing functional blindness even though the eyes and vision are normal. (12 Dec 1998) |
