Inventor: KHALDI NORA
IPC: A61K38/08
Filed: 2020-08-14
Abstract: The Applicant has discovered a number of peptides that are capable of phosphorylating ribosomal protein S6 (rpS6) across a range of concentrations in in-vitro cell assays in a dose-dependent manner. RPS6 is a key substrate for protein kinases and is phosphorylated by growth factors and mitogens during in cell growth and cell division. This is a key step in the synthesis of new proteins in skeletal muscle tissue. The peptides described also have the ability to reduce the expression of mRNA Transcripts (TRIM63 and FBXO32) that are directly linked to increase protein degradation, resulting in progressive Skeletal Muscle Atrophy. In addition, increases in muscular atrophy are linked with systemic rise in circulating TNFα. The peptides described herein also lead to the reduced expression of TNFα in circulating immune cells. The peptides may be used to promote muscle growth and muscle health in subjects that exhibit muscle atrophy, for example elderly subjects, physically inactive people, and subjects that have indications characterised by muscle atrophy (i.e. MS and Polio).

Abstract: A method of determining the optimum threshold for thresholding image pixels and an adaptive thresholder 11 for processing such image pixels. A portion of the image pixel line or lines is examined and the maximum and minimum pixels in the line portion determined. The maximum and minimum pixels are differenced. and the resulting difference signal compared to a constant representing the minimum desired change in background level. Where the difference signal is larger, a new threshold is thereafter used. 
<??>To determine the new threshold level, the difference signal is multiplied by a factor representing the amount of change in threshold for a given event and the result subtracted from the previously determined maximum pixel. The subtracted output is brought within predetermined maximum and minimum threshold constraints to provide the new threshold.

Abstract: In an apparatus which measures an area factor of an image portion of an image-bearing member (11), such as a printing plate used in an offset press, having image and non-image portions with different reflectivities, a single light source (51) and a single photoelectric conversion element (56) are used for measuring reflected light from the image-bearing member (11) by optically scanning the image-bearing member. An arithmetic operation unit (57) is provided so that the reflected light data are measured on the basis of electrical signals from the photoelectric conversion element (56) each time a light beam moves for a unit distance in the X axis direction of the image-bearing member (11), and the corresponding reflected light data are added in the Y axis direction to obtain area data for each unit region in the X axis direction. In the offset press, an area factor of an image portion for each ink control zone of the press is calculated on the basis of the area data forthe respective unit regions and the quantity of ink for each ink control zone is thus controlled.
