Investigation of the Characteristics of NLS-PNA: Influence of NLS Location on Invasion Efficiency

open access: yesApplied Sciences, 2020
Peptide nucleic acid can recognise sequences in double-stranded DNA (dsDNA) through the formation of a double-duplex invasion complex. This double-duplex invasion is a promising method for the recognition of dsDNA in cellula because peptide nucleic acid (

Individual Case Analysis of Postmortem Interval Time on Brain Tissue Preservation. [PDF]

open access: yesPLoS ONE, 2016
At autopsy, the time that has elapsed since the time of death is routinely documented and noted as the postmortem interval (PMI). The PMI of human tissue samples is a parameter often reported in research studies and comparable PMI is preferred when ...

Fabrication of Silver Nanoparticles Against Fungal Pathogens

open access: yesFrontiers in Nanotechnology, 2021
The use of silver nanoparticles (AgNPs) against various pathogens is now being well recognized in the agriculture and health sector. Nanoparticles have been shown to exhibit various novel properties and these properties, on other hand, rely upon the size,

Probing structural heterogeneities and fluctuations of nucleic acids and denatured proteins [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
We study protein and nucleic acid structure and dynamics using single-molecule FRET and alternating-laser excitation. Freely diffusing molecules are sorted into subpopulations based on single-molecule signals detected within 100 μs to 1 ms.

Atomic scissors: a new method of tracking the 5-bromo-2'-deoxyuridine-labeled DNA in situ. [PDF]

open access: yesPLoS ONE, 2012
A new method of the light microscopy detection of BrdU-labeled DNA in situ is described. It is based on the oxidative attack at the deoxyribose moiety by copper(I) in the presence of oxygen, which leads to the abstraction of hydrogen atom from ...

Base composition of DNA in adenovirus-12-induced tumor [PDF]

open access: yes, 1969
A series of experiments was conducted to study the base composition of DNA in AVl2-induced tumor and host cells by paper chromatography, and it was found that DNA per cent. guanine-cystosine contents were around 42 % in both of them. The base composition

Observation of coherent delocalized phonon-like modes in DNA under physiological conditions [PDF]

open access: yes, 2016
Underdamped terahertz-frequency delocalized phonon-like modes have long been suggested to play a role in the biological function of DNA. Such phonon modes involve the collective motion of many atoms and are prerequisite to understanding the molecular ...
