Synthesis and Characterization of Novel Biginelli Dihydropyrimidinone Derivatives Containing Imidazole Moiety

open access: yesJournal of Chemistry, Volume 2019, Issue 1, 2019., 2019
Enaminone, (2E)‐1‐[4‐(1H‐imidazol‐1‐yl) phenyl]‐4‐methylpent‐2‐en‐1‐one (II) was synthesized by refluxing 1‐[4‐(1H‐imidazol‐1‐yl) phenyl] ethan‐1‐one (I) with dimethylforamide dimethylacetal (DMF–DMA) under solvent‐free condition for 12 hours. Finally, the dihydropyrimidinone derivatives containing imidazole moiety (1–15) were obtained by reacting ...

Photodynamic therapy of prostate cancer by means of 5-aminolevulinic acid-induced protoporphyrin IX - In vivo experiments on the dunning rat tumor model [PDF]

open access: yes, 2004
Objective: In order to expand the use of photodynamic therapy (PDT) in the treatment of prostate carcinoma (PCA), the aim of this study was to evaluate PDT by means of 5-aminolevulinic acid (5-ALA)-induced protoporphyrin IX ( PPIX) in an in vivo tumor ...

Preclinical Molecular Imaging for Precision Medicine in Breast Cancer Mouse Models

open access: yesContrast Media &Molecular Imaging, Volume 2019, Issue 1, 2019., 2019
Precision and personalized medicine is gaining importance in modern clinical medicine, as it aims to improve diagnostic precision and to reduce consequent therapeutic failures. In this regard, prior to use in human trials, animal models can help evaluate novel imaging approaches and therapeutic strategies and can help discover new biomarkers.

Monitoring vascular normalization induced by antiangiogenic treatment with 18F‐fluoromisonidazole‐PET

open access: yesMolecular Oncology, Volume 10, Issue 5, Page 704-718, May 2016., 2016
Background: Rationalization of antiangiogenics requires biomarkers. Vascular re‐normalization is one widely accepted mechanism of action for this drug class. The interstitium of tumors with abnormal vasculature is hypoxic. We sought to track vascular normalization with 18F‐misonidazole ([18F]‐FMISO, a probe that detects hypoxia) PET, in response to ...

Stroma Targeting Nuclear Imaging and Radiopharmaceuticals

open access: yesInternational Journal of Molecular Imaging, Volume 2012, Issue 1, 2012., 2012
Malignant transformation of tumor accompanies profound changes in the normal neighboring tissue, called tumor stroma. The tumor stroma provides an environment favoring local tumor growth, invasion, and metastatic spreading. Nuclear imaging (PET/SPECT) measures biochemical and physiologic functions in the human body.

Integrating Imaging Data into Predictive Biomathematical and Biophysical Models of Cancer

open access: yesInternational Scholarly Research Notices, Volume 2012, Issue 1, 2012., 2012
While there is a mature literature on biomathematical and biophysical modeling in cancer, many of the existing approaches are not of clinical utility, as they require input data that are extremely difficult to obtain in an intact organism, and/or require a large number of assumptions on the free parameters included in the models.

Comparison of chemical clustering methods using graph- and fingerprint-based similarity measures [PDF]

open access: yes, 2003
This paper compares several published methods for clustering chemical structures, using both graph- and fingerprint-based similarity measures. The clusterings from each method were compared to determine the degree of cluster overlap. Each method was also

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 ...
