The principal possibility of inhibition of histone deacetylases (HDACs) in nuclear extract of HeLa cells by N1-hydroxy-N4-(pyridine-4-yl)succinamide (compound 1) has been investigated. Compound 1 inhibits HDAC and exhibits low toxicity to A-172, HepG2, HeLa, MCF-7, and Vero cells. HeLa cells are most sensitive to the compound. With an increase in the interval between the administration of compound 1 and a chemotherapeutic agent to 8 hours, an increase in the cytotoxic effect of cisplatin or actinomycin D in HeLa cells was observed. On the other hand, the combination of compound 1 with cisplatin or actinomycin D reduced the cytotoxic effects of these drugs in Vero non-cancerous cells.

The electric double layer (EDL) at a single-crystal metal surface is controlled not only by the electrolyte composition and the electrode potential, but also by the atomic structure of the surface itself. This makes the Ag(hkl)/NaF interface a stringent test for continuum theories of the EDL. In the third part of our series, we examine ...

EEG recordings are often affected by the loss or corruption of individual channels due to electrode detachment, poor scalp contact, or external interference. Such channels must be accurately reconstructed before further analysis. In this study, we investigate Next-Generation Reservoir Computing (NG-RC) as a data-driven approach for reconstructing corrupted EEG channels and compare its performance with ...

A self-consistent statistical-mechanical theory of the Hall effect in electrolyte solutions is developed by extending the self-consistent Debye–Hückel–Onsager (SCDHO) framework to crossed electric and magnetic fields. The theory incorporates non-local ionic charge distributions via Slater-type form factors, regularizing the Coulomb interaction at short range, and accounts for dielectric friction through ion-specific coefficients, employing experimental values ...

The rational design of coinage metal nanocarriers requires a mechanistic understanding of metal-drug binding and predictive descriptors that translate molecular interactions into design rules. Using DFT (B3LYP-D3BJ/def2-TZVP, SMD water), we systematically investigated the binding of 5-fluorouracil (5-FU) and levodopa (l-DOPA) to neutral and cationic homo- and heteronuclear dimers of Au, Ag, and Cu (Au2, Ag2, ...

A pangenome reference overcomes the inherent limitation of any individual reference genome by integrating the variation present in a population. We present the Human Pangenome Reference Consortium’s (HPRC) Release 2 (HPRC2), an openly available, second phase pangenome that is an approximately fivefold expansion in genome number over HPRC Release 1 (HPRC1) and measurable improvement in ...

Bacterial chromosomes are tightly packed in the cells due to interactions with specific nucleoid-associated proteins. Among them, the IHF protein draws attention due to its presumed influence on intracellular crystallization processes, leading to bacterial resistance to drugs. The crystal structure of the IHF heterodimer is known only in complex with a short DNA fragment, whereas ...

Musical training has a significant impact on brain organization, leading to functional and structural
adaptations that enhance auditory, visual, motor, and cognitive processes. This study investigates how
extensive musical training shapes functional brain connectivity by comparing professional musicians and
non-musicians. Using EEG phase-locking value (PLV) analysis, we examined neural synchronization across
alpha, beta, and gamma frequency ranges during music ...

We present two models with explicit long-range electrostatics in the form of Coulomb interactions. Both models include point charges depending on their local atomic environments, and the second model also conserves a total charge of an atomic system. We combine the proposed long-range models with the local moment tensor potential (MTP) and demonstrate that they ...

Density functional theory (DFT) is the workhorse of modern reactions and materials modeling. While the exact functional remains unknown, many approximations to it have been constructed either by hand-crafting functional forms to satisfy exact constraints or by machine learning. In this work, we show how both of these approaches can be fused to build both ...
