Synthetic Tumors Make AI Segment Tumors Better [PDF]
arXiv, 2022 We develop a novel strategy to generate synthetic tumors. Unlike existing works, the tumors generated by our strategy have two intriguing advantages: (1) realistic in shape and texture, which even medical professionals can confuse with real tumors; (2) effective for AI model training, which can perform liver tumor segmentation similarly to a model ...

Label-Free Liver Tumor Segmentation [PDF]
arXiv, 2023 We demonstrate that AI models can accurately segment liver tumors without the need for manual annotation by using synthetic tumors in CT scans. Our synthetic tumors have two intriguing advantages: (I) realistic in shape and texture, which even medical professionals can confuse with real tumors; (II) effective for training AI models, which can perform ...

Approaches to repurposing reverse transcriptase antivirals in cancer
British Journal of Clinical Pharmacology, EarlyView.This review highlights the role of reverse transcriptase (RT) inhibition in cellular regulation associated with non‐terminal repeat retrotransposons and endogenous retroviruses. Based on their pleiotropic characteristics, RT inhibitors (RTIs) are discussed as potential anticancer agents.

Journal of Biophotonics, EarlyView.Photoactivated chemotherapy (PACT), an oxygen‐independent light‐based therapy, utilizes chemotherapeutic regimens that remain inert until exposed to light, allowing target‐specific activation while minimizing off‐target toxicity. The integration of these techniques has the potential to improve selectivity and yield synergistic cytotoxic effects that ...

Primary Renal Carcinoid Tumor Mimicking Non-Clear Cell Renal Cell Carcinoma: A Case Report
대한영상의학회지, 2016 Carcinoid tumors are neoplasms with neuroendocrine differentiation, and they are most commonly found in the gastrointestinal and respiratory systems. Primary renal carcinoid tumor has rarely been reported.

Elastic free energy drives the shape of prevascular solid tumors [PDF]
, 2014 It is well established that the mechanical environment influences cell functions in health and disease. Here, we address how the mechanical environment influences tumor growth, in particular, the shape of solid tumors. In an in vitro tumor model, which isolates mechanical interactions between tumor cells and a hydrogel, we find that tumors grow as ...

Tumor growth with nutrients: stability of the tumor patches [PDF]
arXiv, 2022 In this paper, we study a tumor growth model with nutrients. The contact inhibition for the tumor cells, presented in the model, results in the evolution of a congested tumor patch. We study the regularity of the tumor patch as the nutrients' diffusion strength $D$ diminishes.
