Hypoxia in Head and Neck Squamous Cell Carcinoma

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
Hypoxia is a common feature in most of the solid tumors including head and neck squamous cell carcinoma (HNSCC). Hypoxia reflects the imbalance between oxygen consumption by the rapidly proliferating cancer cells and the insufficient oxygen delivery due to poor vascularization and blood supply.

Synthesis and In Vitro Antibacterial Activity of New 2‐(1‐Methyl‐4‐nitro‐1H‐imidazol‐5‐ylsulfonyl)‐1,3,4‐thiadiazoles

open access: yesJournal of Chemistry, Volume 8, Issue 3, Page 1120-1123, 2011., 2011
In the present study we report the synthesis and antibacterial activity of a new series 2‐(1‐methyl‐4‐nitro‐1H‐imidazol‐5‐ylsulfonyl)‐1,3,4‐thiadiazoles (6a-c). Compounds 6a-c were tested in vitro by the conventional agar dilution method against a panel of microorganisms including gram‐negative and gram‐positive bacteria.

Neon ion (20Ne10+) charged particle beams manipulate rapid tumor reoxygenation in syngeneic mouse models

open access: yesCancer Science, Volume 115, Issue 1, Page 227-236, January 2024.
Quantitative non‐hypoxic (Splatoon) maps of the tumors tested. The Splatoon maps indicate accelerated tumor reoxygenation in the tumors irradiated with neon ions. Abstract Charged particle beams induce various biological effects by creating high‐density ionization through the deposition of energy along the beam's trajectory.

Recent Advances in Image‐Guided Radiotherapy for Head and Neck Carcinoma

open access: yesJournal of Oncology, Volume 2009, Issue 1, 2009., 2009
Radiotherapy has a well‐established role in the management of head and neck cancers. Over the past decade, a variety of new imaging modalities have been incorporated into the radiotherapy planning and delivery process. These technologies are collectively referred to as image‐guided radiotherapy and may lead to significant gains in tumor control and ...

Effect of misonidazole on neurotransmitter systems

open access: yesInternational Journal of Radiation Oncology*Biology*Physics, 1986
This study examines the effect of chronic administration of misonidazole on four neurotransmitter pathways (norepinephrine, dopamine, acetylcholine, and GABA) of the central nervous system (CNS). Biochemical assays examined the neurotransmitter synthesizing enzymes tyrosine hydroxylase (TOH) for catecholamines and choline acetyltransferase (CAT) for ...
