Title: Gene regulation therapy involving ferritin
Inventor: BROYLES ROBERT H
IPC: A61K38/17
Filed: 2001-11-01
Abstract: A method is described for regulating gene expression related to iron metabolism to ameliorate diseases that include sickle cell disease, cancers, neurodegenerative diseases, Friedreich's ataxia and other neuromuscular disorders, and atherosclerosis. This approach is illustrated by recent findings that show that ferritin-H, an iron-binding protein that is present in cell nuclei, can repress the human beta-globin gene, the gene that is mutated in sickle cell disease. Increased expression of ferritin-H or a related ferritin-family peptide, given to effected cells either as the peptide itself (or a part thereof), as an expression clone of the ferritin-H-subfamily gene, or via a gene regulator that increases expression of the ferritin-H-subfamily gene itself, prevents or ameliorates expression of the disease state in disorders where increased availability of iron is implicated in the etiology of the disease, including those named above.

Abstract: A method and apparatus for densely packing wire (11) in a storage drum (62) is provided. A capstan (12) is provided for pulling welding wire (11) at a set rotational velocity. The welding wire (11) is then provided to a rotatable laying head (21) which receives the wire (11) from the capstan (12), and in turn rotates with a storage drum (62) placed on a rotatable turntable (54). As the welding wire (11) is placed within the turntable (54) in layers, the turntable (54) is indexed relative to the storage drum axis and the rotational velocity of the capstan (12) and laying head (21) is altered, which causes the welding wire (11) to be placed in a layer different from the first layer. This indexing is continued until the storage drum (62) is full, forming alternating bands of welding wire (11) to increase the packing density of the storage drum (62).

Inventor: BACHTIGER ROLF
IPC: B61L3/22
Filed: 1997-04-17
Abstract: A process is disclosed for communication systems used in traffic engineering and having an earthbound transponder for each corresponding track section. The transponders transmit first data through a first path of transmission to polling machines arranged on vehicles. Based on these first data, the concerned polling machine ascertains whether second data transmitted through a second path of transmission to the polling machine are really destined for the vehicles. The signal in the second path of transmission destined for the vehicles of a section of the track is individually modulated or transmitted by a time- or frequency-multiplexing process. Depending on the selected modulation or multiplexing, coefficients are built at the emitter side which are then transmitted through the first path of transmission, extracted at the receiver side and used to demodulate or demultiplex the signal transmitted through the second path of transmission. The physical separation of the transmitted signals makes it possible to ascertain whether the signals received through the second path of transmission are destined for this section of the track or the vehicles that circulate thereon.
