Publication number: 20180137621Abstract: A method is disclosed for analysing an image to assess a condition of an organ of a patient represented in the image. The method includes initially selecting a spatial resolution for an inspection matrix having a number of inspection regions each delimiting a part of the image. The inspection matrix is applied to the image and the part of the image within each of the inspection regions is analysed to determine a condition thereof. The condition is compared with a predetermined criterion and, if the condition is deemed to satisfy the criterion, the inspection region is identified, e.g. by annotating it with a colour. Finally a quantitative measure of an extent of the condition in the image is provided that is based on a number of the identified or annotated inspection regions.Type: ApplicationFiled: March 9, 2016Publication date: May 17, 2018Applicants: Telethon Kids Institute, Erasmus University Medical Center RotterdamInventors: Stephen Stick, Tim Rosenow, Harmannus Arnoldus Wilhelmus Maria Tiddens, Marleen De Bruijne

Patent number: 9962127Abstract: A catheter-based optical imaging system for imaging a patient includes a catheter-based imaging device configured to direct optical radiation towards a vessel wall and to receive reflected radiation therefrom. A displacement mechanism is configured to vary the position of the imaging device relative to the catheter as a function of time during an imaging scan. An input is configured to receive cardiac event timing data, such as ECG data, from the patient. A trigger module is configured to initiate an imaging scan based on the cardiac event timing obtained from the cardiac event timing data. By triggering the optical imaging scans between cardiac events, artifacts in the image data can be reduced or eliminated.Type: GrantFiled: March 17, 2014Date of Patent: May 8, 2018Assignee: Erasmus University Medical Center RotterdamInventors: Tianshi Wang, Charles Theodoor Lancee, Antonius Franciscus Wilhelmus Van Der Steen, Gijs Van Soest

Patent number: 9901080Abstract: This invention provides a transgenic mouse for studying the role of senescent cells on an age-related disorder or an age-sensitive trait. The transgene contains a p16 promoter sequence that controls expression of an enzyme so as to cause the enzyme to be expressed in senescent cells in the mouse. The enzyme converts a prodrug to a cytotoxic agent, so that treating the mouse with the prodrug results in the prodrug selectively killing the senescent cells. As a result, progression of an age-related disorder or an age-sensitive trait is delayed. Included is the 3MR mouse model, which also expresses bioluminescent and fluorescent markers under control of the p16 promoter so that senescent cells in the mice can be visualized.Type: GrantFiled: March 11, 2016Date of Patent: February 27, 2018Assignees: Buck Institute for Research on Aging, Erasmus University Medical Center RotterdamInventors: Judith Campisi, Marco Demaria, Remi-Martin Laberge, Francis Rodier, James Mitchell, Jan H.

Patent number: 9901081Abstract: This invention provides a transgenic mouse with a p16INK4a promoter sequence that controls expression of a protein such that it is expressed preferentially in senescent cells. The protein either directly induces apoptosis, or converts a prodrug to a cytotoxic compound. In addition, the mouse is injected with syngeneic tumor cells, or has second transgene that causes tumors to form. Removing senescent cells from the mouse may result in the formation of fewer tumors.Type: GrantFiled: March 25, 2016Date of Patent: February 27, 2018Assignees: Buck Institute for Research on Aging, Erasmus University Medical Center RotterdamInventors: Judith Campisi, Marco Demaria, Francis Rodier, Remi-Martin Laberge, James Mitchell, Jan H.
