Advances in Rapid Nucleic Acid Diagnostics for Hepatitis B and C Viruses: A Comprehensive Review. [PDF]

open access: yesRev Med Virol
ABSTRACT Chronic viral hepatitis, predominantly caused by HBV and HCV infections, remains a major global health burden and a leading cause of cirrhosis, hepatocellular carcinoma (HCC), and liver‐related mortality. Achieving the World Health Organisation (WHO) target of diagnosing 90% of HBV and HCV infections by 2030 necessitates a fundamental ...

Summer legumes following winter wheat boost soil nitrogen availability and corn yield

open access: yesAgronomy Journal, Volume 118, Issue 1, January/February 2026.
Abstract Efficient nitrogen (N) management is critical for improving nitrogen use efficiency (NUE) and sustaining corn (Zea mays L.) yields. We evaluated summer cover crops planted after winter wheat (Triticum aestivum L.) to quantify biomass, N content, soil N dynamics, and subsequent corn performance under rainfed conditions in eastern Nebraska ...

Copper‐Catalyzed Intramolecular Hydrophosphorylation of Alkynes: Straightforward Regio‐ and Stereoselective Access to Six‐Membered Phosphorus Heterocycles

open access: yesEuropean Journal of Organic Chemistry, Volume 28, Issue 48, December 22, 2025.
Ready access to six‐membered phosphorus heterocycles through copper‐catalyzed intramolecular hydrophosphorylation of ortho‐alkynyl secondary phosphine oxides is described. The reaction proceedes with high regio‐ and stereoselectivity. An atom‐economic copper‐catalyzed intramolecular hydrophosphorylation of ortho‐alkynyl secondary phosphine oxides ...

How founders' values enable business model innovation in new ventures: The case of Magnum Photos

open access: yesStrategic Management Journal, Volume 46, Issue 10, Page 2492-2534, October 2025.
Abstract Research Summary This study explores why and how founders' values lead them to design novel business models. To address these questions, we conducted a historical case study of Magnum Photos, a photo agency whose novel business model revolutionized magazine photography in the mid‐20th century.

Enabling Visible Light Sensitization of YbIII, NdIII and ErIII in Dimeric LnIII/GaIII Metallacrowns through Functionalization with RuII Complexes for NIR‐II Multiplex Imaging

open access: yesAngewandte Chemie, Volume 137, Issue 3, January 15, 2025.
LnRu‐3 dimeric LnIII/GaIII metallacrows bearing four RuII chromophoric complexes have been synthesized and proved to exhibit characteristic emissions of YbIII, NdIII and ErIII in the NIR‐II region upon excitation with visible light through metal‐to‐ligand charge transfer (MLCT) states.

The Versatility of Diazirines: Properties, Synthetic and Modern Applications

open access: yesChemistry – A European Journal, Volume 31, Issue 43, August 1, 2025.
Diazirines are 3‐membered heterocycles containing two nitrogen atoms connected by a double bond. They possess a multi‐faceted reactivity that holds great potential for organic synthesis. This review discusses their properties, modes of activation, and their many modern uses, underlining their underappreciated versatility: as carbene precursors, but ...

The Halogen Effect in [Cu(NHC)X] Compounds: A Case Study on the Anti‐Leishmania and Antiviral Activity of [Cu(IPr)X]

open access: yesChemistrySelect, Volume 10, Issue 31, August 15, 2025.
This study explores how changing halidesfrom Cl to Iinfluences ionic radius, antioxidant activity, and lipophilicity. These shifts significantly impact the biological potency of [Cu(IPr)X] compounds against Leishmania parasites and arboviruses. A strategic tweak in halogen identity paves the way for enhanced therapeutic performance in metal‐based drug ...

Simulating evaporative wet and dry cycles in Gale crater, Mars using thermochemical modeling techniques

open access: yesMeteoritics &Planetary Science, Volume 60, Issue 8, Page 1704-1720, August 2025.
Abstract The aim of this work is to provide a model‐backed hypothesis for the formation of evaporites—sulfates, borates—in Gale crater using thermochemical modeling to determine constraints on their formation. We test the hypothesis that primary evaporites required multiple wet–dry cycles to form, akin to how evaporite assemblages form on Earth ...
