Single molecule DNA sequencing via transverse electronic transport using a graphene nanopore: A tight-binding approach

open access: yes, 2016
We report a tight-binding model study of two-terminal graphene nanopore based device, for sequential determination of DNA bases. Using Greens function approach we calculate conductance spectra, I-V response and also the changes in local density of states

Epigenetic Changes Related to Hypertension in Asian Adults: A Systematic Review

open access: yesChronic Diseases and Translational Medicine, EarlyView.
PRISMA study flow diagram. ABSTRACT Background Elevated high blood pressure is controlled by complicated, little‐understood genetic and epigenetic pathways that are influenced by both heritable and environmental variables. Many adult systolic and diastolic blood pressure‐related genomic loci have been identified through previous genome‐wide association

Hydrophilic interaction liquid chromatography coupled to quadrupole-time-of-flight mass spectrometry for determination of nuclear and cytoplasmatic contents of nucleotides, nucleosides and their nucleobases in food yeasts

open access: yesTalanta Open, 2021
Hydrophilic interaction liquid chromatography using a zwitterionic phase, coupled with high-resolution mass spectrometry based on quadrupole and time-of-flight mass analyser (HILIC-Q-TOF-MS) is applied for the determination of four nucleobases (adenine ...

Chirality in a quaternionic representation of the genetic code [PDF]

open access: yesarXiv, 2015
A quaternionic representation of the genetic code, previously reported by the authors, is updated in order to incorporate chirality of nucleotide bases and amino acids. The original representation assigns to each nucleotide base a prime integer quaternion of norm 7 and involves a function that associates with each codon, represented by three of these ...

Polymerase Synthesis of Hypermodified DNA Displaying a Combination of Thiol, Hydroxyl, Carboxylate, and Imidazole Functional Groups in the Major Groove

open access: yesChemistry – A European Journal, EarlyView.
A series of 2’‐deoxyribonucleoside 5’‐O‐triphosphates bearing functional groups of amino acid side chains in enzyme active sites (OH, SH, COOH, and imidazole) were synthesized and used for enzymatic synthesis of hypermodified DNA displaying these substituents in the major groove mimicking peptides or proteins. Abstract We designed and synthesized a set
