New geographical records for tick‐borne pathogens in ticks collected from cattle in Benin and Togo

Veterinary Medicine and Science, Volume 9, Issue 1, Page 345-352, January 2023., 2023
A total of 396 ticks were collected from cattle between 2019 and 2020, and divided in pools (two to six ticks per pool) for molecular screening. The present study highlights the presence of zoonotic agents in ticks collected from cattle in Benin and Togo.

Nanosecond Hyperquenching for Electron Cryo‐Microscopy Without Air‐Water Interface Artifacts

Chemistry – A European Journal, EarlyView.
A novel method for the ultrafast vitrification of the biological assemblies is assayed by the electron cryotomography. Protein specimens prepared by this method inherently lack the spatial/structural artifacts, which derive from the surface tension at the air‐water interface (AWI).

A Cytotoxic Indazole‐based Gold(III) Carboxamide Pincer Complex Targeting DNA Through Dual Binding Modes of Groove Binding and Alkylation

Chemistry – A European Journal, EarlyView.
Toward new gold(III) anticancer agents. Herein, we report on an indazole‐based gold(III) carboxamide pincer complex exhibiting significant cytotoxicity, likely mediated through dual interactions with DNA. Mechanistic investigations suggest that the complex binds to the DNA and forms specific interactions with nucleotide bases.

Tunable G‐Quadruplex Ligands: Azobenzene Derivatives for Light‐Controlled DNA Modulation

Chemistry – A European Journal, EarlyView.
Azobenzene (AB) is a promising light‐responsive motif for targeting G‐quadruplexes (G4 s) and enabling their light‐controlled modulation. We synthesized a series of novel AB derivatives with diverse structural variations, demonstrating that the interaction mode influences its ability to modulate G4 properties bidirectionally.

Using electropolymerization based doping for electro-addressable functionalization of a multi-electrode array probe for nucleic acid detection [PDF]

arXiv, 2017
Here, we report a facile method for electro-addressable functionalization of a probe comprising of closely spaced three individually addressable carbon fiber electrodes for detection of nucleic acids. First, a multi electrode array probe comprising three adjacent carbon fiber electrodes was fabricated through pulling a three-barrel glass capillary with
