The Excited State Dynamics of a Mutagenic Guanosine Etheno Adduct Investigated by Femtosecond Fluorescence Spectroscopy and Quantum Mechanical Calculations

open access: yesChemistry – A European Journal, Volume 30, Issue 49, September 2, 2024.
The mutagenic etheno adduct of guanine exhibits a peculiar behavior of its lowest singlet excited state. The two independent and short‐lived emission bands revealed by femtosecond upconversion fluorescence are associated with two strongly coupled bright minima of different geometry.

Multiscale Systems‐Pharmacology Pipeline to Assess the Prophylactic Efficacy of NRTIs Against HIV‐1

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 5, Issue 7, Page 377-387, July 2016., 2016
While HIV‐1 continues to spread, the use of antivirals in preexposure prophylaxis (PrEP) has recently been suggested. Here we present a modular systems pharmacology modeling pipeline, predicting PrEP efficacy of nucleotide reverse transcriptase inhibitors (NRTIs) at the scale of reverse transcription, target‐cell, and systemic infection and after ...

Multiple Factors Determine the Oncolytic or Carcinogenic Effects of TLRs Activation in Cancer

open access: yesJournal of Immunology Research, Volume 2024, Issue 1, 2024.
Toll‐like receptors (TLRs) belong to a germline‐encoded protein family. These are pattern recognition receptors. They sense pathogen‐associated molecular patterns (PAMPs). When this occurs, activation of the NF‐ĸB pathway follows. This triggers the innate immune response of the host.

Spectroscopic, Electrochemical, and In Silico Characterization of Complex Formed between 2‐Ferrocenylbenzoic Acid and DNA

open access: yesJournal of Chemistry, Volume 2016, Issue 1, 2016., 2016
We present the synthesis of 2‐ferrocenylbenzoic acid (FcOH) and its electrochemical and spectroscopic characterization. FcOH was characterized for interaction with DNA using theoretical and experimental methods. UV‐visible spectroscopy and cyclic voltammeter (CV) were used for the experimental account of FcOH‐DNA complex.

Supplementation of Nucleotides to Enhance Performance and Immune Responses of Asian Seabass [PDF]

open access: yes, 2021
Supplementation of nucleotides into fish diets can be an alternative method to manage disease problems in aquaculture, since it was reported could improve the growth rate and immunity of some aquaculture species. The present study assessed the growth and

Modified Nucleotides for Discrimination between Cytosine and the Epigenetic Marker 5‐Methylcytosine

open access: yes, 2016
5-Methyl-2'-deoxycytosine, the most common epigenetic marker of DNA in eukaryotic cells, plays a key role in gene regulation and affects various cellular processes such as development and carcinogenesis.

Profile of Nucleosides and Nucleotides in Donkey's Milk.

open access: yes, 2014
Nucleotides play a crucial role to cellular functions; they can be obtained from the diet or through the nucleotide salvage pathway, however, in particular situations (occurring mainly in newborns) the metabolic demand of nucleotides exceeds the capacity

Activation of NADPH oxidase by purine and pyrimidine nucleotides involves G proteins and is potentiated by chemotactic peptides [PDF]

open access: yes, 1989
Human neutrophils and HL-60 leukaemic cells possess an NADPH oxidase which catalyses superoxide (O2-) formation and is activated by the chemotactic peptide, N-formyl-L-methionyl-L-leucyl-L-phenylalanine (fMet-Leu-Phe).
