4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase in malaria parasites and enhances atovaquone efficacy

FEBS Letters, Volume 600, Issue 2, Page 251-266, January 2026.
Atovaquone is an antimalarial requiring potentiation for sufficient efficacy. We pursued strategies to enhance its activity, showing that 4‐nitrobenzoate inhibits 4‐hydroxybenzoate polyprenyltransferase, decreasing ubiquinone biosynthesis. Since atovaquone competes with ubiquinol in mitochondria, 4‐nitrobenzoate facilitates its action, potentiating ...

Unveiling Dipolar Interaction‐Driven Magnetic Field Inhomogeneities in T2 MRI Contrast Agents

Advanced Science, Volume 13, Issue 3, 14 January 2026.
In this study, chemically designed nanoscale‐distance‐tuned based on silica‐coated iron oxide nanoparticles are used to investigate how dipolar interactions affect magnetic resonance imaging (MRI) contrast. By varying shell thickness, researchers modulated dipolar interactions and observed an exponential increase in transverse relaxivity (r2) that ...

Aptamer Engineering: Strategies for Discovering Functional Nucleic Acids for Next‐Generation Diagnostics and Biosensing

Advanced Science, Volume 13, Issue 2, 9 January 2026.
The advent of aptamers has highlighted their potential as alternatives to antibodies, overcoming limitations of structural instability and production cost. However, conventional approaches such as SELEX remain slow and labor‐intensive. This review examines recent advances in aptamer engineering, emphasizing in vitro and AI‐driven in silico strategies ...

Analysis into the viability of pea gravel as a diffusing material for biostimulation systems in petroleum hydrocarbon‐contaminated soils

Journal of Environmental Quality, Volume 55, Issue 1, January/February 2026.
Abstract Injecting biostimulatory solutions around underground storage tanks (UGSTs) promotes petroleum hydrocarbon (PHC) bioremediation without the use of intrusive infrastructure. Yet, it is unclear how the interaction between porous bedding material (i.e., pea gravel) and biostimulatory solutions impacts PHC biodegradation rates.

A pyrazolopyran derivative preferentially inhibits the activity of human cytosolic hydroxymethyltransferase and induces cell death in lung cancer cells [PDF]

, 2015
Serine hydroxymethyltransferase (SHMT) is a central enzyme in the metabolic reprogramming of cancer cells, providing activated one-carbon units in the serine-glycine one-carbon metabolism.

Novel method for determining of 137Cs in seawater using liquid scintillation counter

Limnology and Oceanography: Methods, Volume 24, Issue 1, January 2026.
Abstract Robust and efficient monitoring of radiocesium in the marine environment has become increasingly important, especially following the Fukushima Daiichi Nuclear Power Plant accident. A liquid scintillation counter (LSC) has been used for 137Cs analysis—which was identified as one of the hazardous radionuclides; however, a major limitation of ...
