PLoS One

January 2025

Organic Plant Production and Agroecosystems Research in the Tropics and Subtropics, Universität Kassel, Kassel, Germany.

Sand, shaping both natural waterways and urban infrastructure, has recently seen a major surge in extraction, particularly in rapidly urbanizing regions like West Africa. To assess the organization, quantification, and socio-ecological implications of sand mining around Mali's capital Bamako, we employed a mixed methods approach including structured and unstructured interviews, truck counts, turbidity analyses, and river depth measurements. Our study identified five artisanal systems for mining sand and gravel from the Niger River, using tied-up pirogues, single pirogues, carts, tractors, and trucks.

Article Synopsis
  • Laser-structuring techniques, particularly Direct Laser Interference Patterning, can significantly enhance the performance of pure Ni electrodes in water electrolysis by optimizing their structure.
  • A study revealed that the spatial distance between laser-structures is critical for improving electrode performance, resulting in an increase in the electrochemically active surface area by up to 12 times compared to nonstructured electrodes.
  • Optimal structuring leads to lower onset potential and overpotential during the oxygen evolution reaction due to the superhydrophilic surface, which enhances bubble growth dynamics and minimizes electrode resistance.

Post-stroke aphasia is a network disorder characterized by language impairments and aberrant network activation. While patients with post-stroke aphasia recover over time, the dynamics of the underlying changes in the brain remain elusive. Neuroimaging work demonstrated that language recovery is a heterogeneous process, characterized by varying activation levels in several regions of the left-hemispheric language network and the domain-general bilateral multiple-demand network.

The ternary transition-metal cyanamide MnCr(NCN) was synthesized by a solid-state metathesis reaction between MnCl, CrCl, and ZnNCN. Powder X-ray diffraction reveals that MnCr(NCN) adopts an orthorhombic [NiAs]-derived structure with symmetry, featuring a hexagonally close-packed array of NCN with metal cations in 3/4 of the octahedral interstitial holes. The question of cation order was addressed via the combinatorial use of X-ray powder diffraction, neutron powder diffraction, electron diffraction, and HAADF-STEM measurements.

J Chem Inf Model

January 2025

Schrödinger Incorporated, Cambridge, Massachusetts 02142, United States.

Article Synopsis
  • Predicting how well ligands bind to nucleic acids is challenging, which limits the development of small-molecule drugs for diseases like cancer and infections.
  • Recent advancements in computational methods, particularly free-energy perturbation (FEP), have improved predictions for protein-ligand binding affinities, but its effectiveness for nucleic acids was unclear.
  • This study found that using FEP+ software with the OPLS4 force field can accurately predict binding energies for over 100 ligands interacting with DNA/RNA, achieving predictions that closely match experimental data and could aid drug discovery.

Genomic data on from the African continent are currently lacking, resulting in the region being under-represented in global analyses of infection (CDI) epidemiology. For the first time in Nigeria, we utilized whole-genome sequencing and phylogenetic tools to compare isolates from diarrhoeic human patients (=142), livestock (=38), poultry manure (=5) and dogs (=9) in the same geographic area (Makurdi, north-central Nigeria) and relate them to the global population. In addition, selected isolates were tested for antimicrobial susceptibility (=33) and characterized by PCR ribotyping (=53).

Background: Autosomal dominant polycystic kidney disease (ADPKD) is caused primarily by pathogenic variants in the PKD1 and PKD2 genes. Although the type of ADPKD variant can influence disease severity, rare, hypomorphic PKD1 variants have also been reported to modify disease severity or cause biallelic ADPKD. This study examines whether rare, additional, potentially protein-altering, non-pathogenic PKD1 variants contribute to ADPKD phenotypic outcomes.
