Efficient Formation of the Tandem Thymine Glycol/8-Oxo-7,8-dihydroguanine Lesion in Isolated DNA and the Mutagenic and Cytotoxic Properties of the Tandem Lesions in Escherichia coli Cells

open access: yes, 2016
Reactive oxygen species can induce the formation of not only single-nucleobase lesions, which have been extensively studied, but also tandem lesions. Herein, we report a high frequency of formation of a type of tandem lesion, where two commonly observed ...

DNA Damage by Ionizing Radiation: Tandem Double Lesions by Charged Particles

open access: yes, 2005
Oxidative damages by ionizing radiation are the source of radiation-induced carcinogenesis, damage to the central nervous system, lowering of the immune response, as well as other radiation-induced damages to human health.

Formation and Genotoxicity of Novel Oxidatively Generated Tandem DNA Lesions and N2-(1-carboxyethyl)-2'-deoxyguanosine [PDF]

open access: yes, 2009
Exogenous and endogenous agents can induce the formation of both single- and tandem-nucleobase lesions in DNA. In this dissertation, we assessed the formation and genotoxicity of three different types of DNA lesions; a novel guanine-thymine intrastrand ...

Intravenous Thrombolysis Benefits Mild Stroke Patients With Large-Artery Atherosclerosis but No Tandem Steno-Occlusion

open access: yesFrontiers in Neurology, 2020
At present, there is controversy regarding whether thrombolysis is beneficial for patients suffering from a mild stroke. In this study, we therefore sought to determine whether the therapeutic benefit of thrombolysis is dependent upon stroke subtype for ...

Synthesis and Thermodynamic Studies of Oligodeoxyribonucleotides Containing Tandem Lesions of Thymidine Glycol and 8-Oxo-2‘-deoxyguanosine

open access: yes, 2016
Thymidine glycol (Tg), which is also known as 5,6-dihydroxy-5,6-dihydrothymidine, and 8-oxo-7,8-dihydro-2‘-deoxyguanosine (8-oxodG) are two major types of DNA damage products induced by reactive oxygen species (ROS).

Endovascular management of tandem embolic stroke due to cardioembolic free-floating thrombus: a case report

open access: yesFrontiers in Neuroscience
BackgroundTandem lesions (TLs), defined as simultaneous occlusions of both extracranial and intracranial arteries, represent a particularly challenging subset of large vessel occlusion (LVO) strokes.

Cartilage Delamination Flap Mimicking a Torn Medial Meniscus

open access: yesCase Reports in Orthopedics, 2016
We report a case of a chondral delamination lesion due to medial parapatellar plica friction syndrome involving the medial femoral condyle. This mimicked a torn medial meniscus in clinical and radiological presentation.
