Title: Remedy for cag repeat expansion diseases
Inventor: TSUJI SHOJI
IPC: A61P25/00
Filed: 1999-01-25
Abstract: To elucidate the molecular mechanisms of "gain of toxic function" of expanded polyglutamine stretches in CAG repeat expansion diseases, the inventorsestablished an expression system of full-length and truncated cDNAs for dentatorubral-pallidoluysian atrophy (DRPLA) and found that truncated DRPLA proteins containing the expanded polyglutamine stretch, but not the full-length protein, form peri- and intra-nuclear aggregates consisting of filaments and concomitant apoptosis. The apoptotic cell death was partially suppressed by transglutaminase inhibitors, cystamine and monodansyl cadaverine, raising the possibility of involvement of transglutaminase reaction. The results may providea potential basis for the development of therapeutic measures for CAG repeat expansion diseases.

Title: Determination of leak and respiratory airflow
Inventor: BERTHON-JONES MICHAEL
IPC: A61M16/00
Filed: 1997-08-14
Abstract: Methods and apparatus for determining leak and respiratory airflow are disclosed. A pressure sensor (34) and a differential pressure sensor (32) have connection with a pneumotach (24) to derive instantaneous mask pressure and airflow respectively. A microcontroller (38) estimates a non-linear conductance of any leak path occuring at a mask (12) as being the low pass filtered instantaneous airflow divided by the low pass filtered square root of the instantaneous pressure. The instantaneous leak flow is then the conductance multiplied by the square root of the instantaneous pressure, and the respiratory airflow is calculated as being the instantaneous airflow minus the instantaneous leak flow. The time constants for the low pass filtering performed by the microcontroller (38) can be dynamically adjusted dependent upon sudden changes in the instananeous leak flow.
