115 results about "Tumor progression" patented technology

Tumor progression is the third and last phase in tumor development. This phase is characterised by increased growth speed and invasiveness of the tumor cells. As a result of the progression, phenotypical changes occur and the tumor becomes more aggressive and acquires greater malignant potential. Together with the progression, more and more aneuploidy occurs. This may be evident as nuclear polymorphism.

Multimodal Deep Learning to Differentiate Tumor Recurrence from Treatment Effect in Human Glioblastoma

A computer implemented method of distinguishing tumor progression from treatment-related necrosis in digital images of a subject implements a multimodal deep learning architecture from MRI data of a selected anatomical portion of the subject, such as a brain, and corresponding dPET data for the subject with a tracer applied to the anatomical portion of the subject. The computer stores co-registered MRI data frames with dPET data frames as three dimensional (3D) parametric PET maps to identify multi-modal image features of segmented tumor data. A convolutional neural network uses MRI data and selected multi-modal image features as inputs and the computer concatenates respective output latent feature vectors from the respective sections of the at least one CNN. Feeding concatenated feature vectors to fully connected layers of the multimodal architecture distinguishes tumor progression from treatment-related necrosis of the anatomical portion of the subject.

Application of pentenedioic acid in enhancing anti-tumor effect of T cells through metabolic reprogramming

The invention provides application of pentenedioic acid (GC) in enhancing the anti-tumor effect of T cells through metabolic reprogramming, and belongs to the technical field of biological medicine. It is found that in the tumor development process, GC is supplemented in an exogenous mode, tumor growth can be rapidly inhibited, and the anti-tumor effect depends on a TME regulation and control mechanism.
