Novel methodology to quantify dehydration in head and neck cancer radiotherapy using DIXON MRI

Journal of Medical Radiation Sciences, Volume 69, Issue 4, Page 448-455, December 2022., 2022
Head and neck cancer (HNC) patients are at risk of weight change, due to inadequate nutrition intake or dehydration, when receiving radiotherapy (RT). 4This study aimed to develop methodology to measure water content changes on magnetic resonance imaging (MRI) scans of the head and neck region over the course of RT.

The Regulation of Trace Metal Elements in Cancer Ferroptosis

Advanced Biology, EarlyView.
The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Long noncoding RNA CDKN2B‐AS1 silencing protects against esophageal cancer cell invasion and migration by inactivating the TFAP2A/FSCN1 axis

The Kaohsiung Journal of Medical Sciences, Volume 38, Issue 12, Page 1144-1154, December 2022., 2022
Abstract Esophageal cancer (EC) is the most aggressive malignancy in the gastrointestinal tract. Long noncoding RNA cyclin‐dependent kinase inhibitor 2 B antisense RNA 1 (CDKN2B‐AS1) is implicated in EC development. However, the specific mechanisms involved remain poorly defined.

H2O2‐Generating Advanced Nanomaterials for Cancer Treatment

Advanced Functional Materials, EarlyView.
H2O2‐generating nanoplatforms can exploit tumor redox imbalance for O2 and toxic reactive oxygen species generation, leading to hypoxia reversal, and apoptosis of cancer cells, respectively. This review highlights the mechanisms of these nanoplatforms, including exogenous H₂O₂ delivery, endogenous amplification, and metal peroxides, which leads to ...

NeoUNet: Towards accurate colon polyp segmentation and neoplasm detection [PDF]

arXiv, 2021
Automatic polyp segmentation has proven to be immensely helpful for endoscopy procedures, reducing the missing rate of adenoma detection for endoscopists while increasing efficiency. However, classifying a polyp as being neoplasm or not and segmenting it at the pixel level is still a challenging task for doctors to perform in a limited time.
