Correlating Structure and KA2 Catalytic Activity of ZnII Hydrazone Complexes

open access: yesEuropean Journal of Inorganic Chemistry, Volume 26, Issue 33, November 24, 2023., 2023
In this manuscript, the synthesis, characterization, and crystal structures of ZnII complexes bearing hydrazone ligands are described. The complexes were evaluated as possible catalysts in the ketone‐amine‐alkyne coupling reaction. Insights into the catalytic activity of the ZnII complexes were obtained by electronic structure investigations, using DFT

A 3D Genome Atlas of Genetic Variants and Their Pathological Effects in Cancer

open access: yesAdvanced Science, Volume 12, Issue 19, May 22, 2025.
The hierarchical organization of the eukaryotic genome is vital for nuclear function, and disruptions from genetic mutations can alter this 3D architecture. Cataloging thousands of interchromosomal translocations, structural variants, and single nucleotide polymorphisms, their impact on 3D genome organization is revealed. The scoring algorithm, 3DFunc,

Spontaneous Cyclization of 2‐Methylthiosemicarbazones Yields New 1,2,4‐Triazolidine‐3‐thiones, Useful as Building Blocks for Drug Design

open access: yesChemistrySelect, Volume 10, Issue 2, January 15, 2025.
This study represents a simple and straightforward synthetic approach to the formation of new cyclic 1,2,4‐triazolidine‐3‐thione compounds. The reaction of 2‐methylthiosemicarbazide with ketones leads to 2‐methylthiosemicarbazone cyclization, yielding 1,2,4‐triazolidine‐3‐thiones. Selected compounds were tested for cytotoxicity, antimicrobial activity,

Detection of Effective Devices in Information Dissemination on the Complex Social Internet of Things Networks Based on Device Centrality Measures

open access: yesComplexity, Volume 2025, Issue 1, 2025.
The Complex Social Internet of Things (CSIoT) integrates the connectivity of IoT with the relational dynamics of complex social networks, creating systems where devices autonomously form and manage relationships. The centrality measures specify the topological characteristics of each node in terms of local and global information of the node in the ...

Sea‐Level Rise, Drinking Water Quality and the Economic Value of Coastal Tourism in North Carolina

open access: yesWater Resources Research, Volume 60, Issue 11, November 2024.
Abstract We estimate the economic benefits of avoiding reductions in drinking water quality due to sea level rise accruing to North Carolina (NC) coastal tourists. Using stated preference methods and responses from recent coastal visitors, we find that tourists are 2%, 8%, and 11% less likely to take an overnight trip if drinking water tastes slightly,

Microbial Dormancy Supports Multi‐Species Coexistence Under Resource Fluctuations

open access: yesEcology Letters, Volume 27, Issue 9, September 2024.
The mechanism by which microbial dormancy gives rise to the density‐dependent feedbacks required for stable coexistence under resource fluctuations is not well understood. We show that the stable coexistence of dormancy and non‐dormancy strategists can emerge via relative nonlinearity of competition and that dormants can coexist alongside gleaner and ...

Pre‐Flight and In‐Flight Calibration and Performance of the Terminal Tracking Cameras (TTCams) on the NASA Lucy Mission

open access: yesEarth and Space Science, Volume 11, Issue 8, August 2024.
Abstract The Terminal Tracking Camera (TTCam) imaging system on the NASA Lucy Discovery mission consists of a pair of cameras that are being used mainly as a navigation and target acquisition system for the mission's asteroid encounters. However, a secondary science‐focused function of the TTCam system is to provide wide‐angle broadband images over a ...

Degenerate oligonucleotide primer MIG‐seq: an effective PCR‐based method for high‐throughput genotyping

open access: yesThe Plant Journal, Volume 118, Issue 6, Page 2296-2317, June 2024.
SUMMARY Next‐generation sequencing (NGS) library construction often involves using restriction enzymes to decrease genome complexity, enabling versatile polymorphism detection in plants. However, plant leaves frequently contain impurities, such as polyphenols, necessitating DNA purification before enzymatic reactions.

Interleukin‐38: A crucial player in periodontitis

open access: yesOral Diseases, Volume 30, Issue 4, Page 2523-2532, May 2024.
Abstract Background The objective of this study was to compare the levels of gingival crevicular fluid (GCF), salivary, and serum matrix metalloproteinase‐9, interleukin (IL)‐17, IL‐36γ, and IL‐38 in individuals with healthy periodontium, gingivitis, and periodontitis and to evaluate their correlations with clinical periodontal parameters.

Investigations into the AuI and PtII Coordination Chemistry of Bidentate “cis‐Spanning” Ligands

open access: yesEuropean Journal of Inorganic Chemistry, Volume 27, Issue 8, March 12, 2024.
The novel long‐range “cis‐spanning” PP ligand LPP coordinates AuCl and Pt(CNC) in a highly selective manner. Subsequent halide abstraction gives rise to the formation of a Au−Pt bond. While the “cis‐spanning” PN ligand LPN does not allow for the generation of heterodinuclear complexes with a metal–metal bond, its potential to serve as a ditopic ligand ...
