DNA damage-site recognition by lysine conjugates [PDF]

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2007
Simple lysine conjugates are capable of selective DNA damage at sites approximating a variety of naturally occurring DNA-damage patterns. This process transforms single-strand DNA cleavage into double-strand cleavage with a potential impact on gene and cancer therapy or on the design of DNA constructs that require disassembly at a specific location ...

Vibration-based damage detection in an aircraft wing scaled model using principal component analysis and pattern recognition [PDF]

open access: yes, 2008
This study deals with vibration-based fault detection in structures and suggests a viable methodology based on principal component analysis (PCA) and a simple pattern recognition (PR) method. The frequency response functions (FRFs) of the healthy and the

Dynamics and energetics of PCBP1 binding to severely oxidized RNA

open access: yesFrontiers in Molecular Biosciences, 2022
Oxidatively generated lesions such as 8-oxo-7, 8-dihydroguanine (8-oxoG) on RNA strands constitute a hallmark marker of the oxidative stress in the cell.

Nucleotide excision repair: a versatile and smart toolkit

open access: yesActa Biochimica et Biophysica Sinica, 2022
Nucleotide excision repair (NER) is a major pathway to deal with bulky adducts induced by various environmental toxins in all cellular organisms. The two sub-pathways of NER, global genome repair (GGR) and transcription-coupled repair (TCR), differ in ...

A BP Neural Network Method for Grade Classification of Loose Damage in Semirigid Pavement Bases

open access: yesAdvances in Civil Engineering, 2021
This study aims to address the problem that loose damage of the pavement base course cannot currently be quantitatively identified, and thus the classification and recognition of the extent of looseness mainly rely on empirical judgments.
