Malignant Solitary Fibrous Tumor of Tandem Lesions in the Skull and Spine

Journal of Korean Neurosurgical Society, 2013
A Solitary Fibrous Tumor (Sft) Is A Rare Neoplasm Originated From The Pleura, But They Can Occur In A Variety Of Extrathoracic Regions. Although Many Cases Of Primary Sft Have Been Reported, There Are Extremely Rare Repots To Date Of A Malignant Sft In The Spine Or Skull.

Computer-assisted detection versus conventional colonoscopy for proximal colonic lesions: a multicenter, randomized, tandem-colonoscopy study

, 2023
Background and Aims: Computer-assisted detection (CADe) is a promising technologic advance that enhances adenoma detection during colonoscopy. However, the role of CADe in reducing missed colonic lesions is uncertain.

Successful treatment of tandem calcific right coronary artery stenoses with 50 mm tapered Biomime Morph stent guided by intravascular ultrasound and rotablation using a sheathless guide via the radial access

IHJ Cardiovascular Case Reports, 2019
Tandem and/or diffuse calcific coronary stenoses can present significant challenges during percutaneous coronary intervention (PCI). Often, these long lesions require treatment with multiple stents of different calibers. However, this approach can result

Cross-Linked Thymine-Purine Base Tandem Lesions:  Synthesis, Characterization, and Measurement in γ-Irradiated Isolated DNA

, 2016
5-(Phenylthiomethyl)-2‘-deoxyuridine has been recently shown to be a specific photolabile precursor of 5-(2‘-deoxyuridilyl)methyl radical that is involved in the formation of tandem base lesion with vicinal guanine in oxygen-free aqueous solution.

Characterization and Mechanism of Formation of Tandem Lesions in DNA by a Nucleobase Peroxyl Radical

, 2016
5,6-Dihydro-2‘-deoxyuridin-6-yl (1) was independently generated via photolysis of 3. The radical is an analogue of the major reactive species produced from thymidine upon reaction with hydroxyl radical, which is the dominant DNA-damaging agent produced ...

The Influence of Single, Tandem, and Clustered DNA Damage on the Electronic Properties of the Double Helix: A Theoretical Study

Molecules, 2020
Oxidatively generated damage to DNA frequently appears in the human genome as the effect of aerobic metabolism or as the result of exposure to exogenous oxidizing agents, such as ionization radiation.

Tandem Lesions Arising from 5‑(Uracilyl)methyl Peroxyl Radical Addition to Guanine: Product Analysis and Mechanistic Studies

, 2019
The reaction of hydroxyl radical (HO•) with thymine in DNA generates 5-(uracilyl)-methyl radicals (T•) and the corresponding methylperoxyl radical (TOO•) in the presence of O2, which in turn propagates damage by reacting with a vicinal nucleobase.

Tandem Lesions in Anterior Circulation Stroke: Analysis of the German Stroke Registry-Endovascular Treatment

, 2021
Background and Purpose: Tandem lesions in the anterior circulation account for up to 30% of all large vessel occlusion strokes. The optimal periprocedural approach in these lesions is still a matter of debate.
