Mechanisms for Tuning Engineered Nanomaterials to Enhance Radiation Therapy of Cancer

open access: yesAdvanced Science, Volume 7, Issue 24, December 16, 2020., 2020
Engineered nanomaterials that produce reactive oxygen species on exposure to X‐ and gamma‐rays used in radiation therapy offer promise of novel cancer treatment strategies including in deep tissue. This review focuses on mechanisms underpinning rational nanomaterial design to enhance radiation therapy, the understanding of which will enable novel ways ...

Effect of radiochemotherapy on T2* MRI in HNSCC and its relation to FMISO PET derived hypoxia and FDG PET

open access: yesRadiation Oncology, 2018
Background To assess the effect of radiochemotherapy (RCT) on proposed tumour hypoxia marker transverse relaxation time (T2*) and to analyse the relation between T2* and 18F-misonidazole PET/CT (FMISO-PET) and 18F-fluorodeoxyglucose PET/CT (FDG-PET ...

In vitro metabolism of misonidazole [PDF]

open access: yesBritish Journal of Cancer, 1981
Misonidazole (MISO) is a nitroimidazole drug currently undergoing clinical trials as a radiosensitizer of hypoxic tumour cells. The drug is also toxic to such cells, probably because of metabolic activation of the nitro group under hypoxia. The metabolic fate of 14C-labelled MISO is examined, using hypoxic mammalian (CHO) cells in vitro.

Absence of a dose-rate effect in the transformation of C3H 10T1/2 cells by α-particles [PDF]

open access: yes, 1987
The findings of Hill et al. (1984) on the greatly enhanced transformation frequencies at very low dose rates of fission neutrons induced us to perform an analogous study with -particles at comparable dose rates. Transformation frequencies were determined

RRx-001, A novel dinitroazetidine radiosensitizer. [PDF]

open access: yes, 2016
The 'holy grail' in radiation oncology is to improve the outcome of radiation therapy (RT) with a radiosensitizer-a systemic chemical/biochemical agent that additively or synergistically sensitizes tumor cells to radiation in the absence of significant ...

Tumor hypoxia and reoxygenation: the yin and yang for radiotherapy. [PDF]

open access: yes, 2016
Tumor hypoxia, a common feature occurring in nearly all human solid tumors is a major contributing factor for failures of anticancer therapies. Because ionizing radiation depends heavily on the presence of molecular oxygen to produce cytotoxic effect ...

Neurotoxicity [PDF]

open access: yes, 2014
Neurotoxicity refers to the direct or indirect effect of chemicals that disrupt the nervous system of humans or animals. Numerous chemicals can produce neurotoxic diseases in humans, and many more are used as experimental tools to disturb or damage the ...

Hypoxia as a barrier to immunotherapy in pancreatic adenocarcinoma

open access: yesClinical and Translational Medicine, Volume 8, Issue 1, December 2019., 2019
AbstractPancreatic ductal adenocarcinoma (PDA) is a lethal disease with limited response to cytotoxic chemoradiotherapy, as well as newer immunotherapies. The PDA tumor microenvironment contains infiltrating immune cells including cytotoxic T cells; however, there is an overall immunosuppressive milieu.

Radiosensitizers in cervical cancer. Cisplatin and beyond [PDF]

open access: yes, 2006
Cervical cancer continues to be a significant health burden worldwide. Globally, the majority of cancers are locally advanced at diagnosis; hence, radiation remains the most frequently used therapeutical modality. Currently, the value of adding cisplatin
