Impact of Sugarcane Management Practices and Time Periods on Soil Organic Carbon and δ13C Signature After Paddy Rice Conversion

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Land use change (LUC) from paddy rice to sugarcane cultivation strongly influences soil organic carbon (SOC) stocks, with the extent and direction of change depending on residue management and time since conversion. This study aimed to (i) evaluate SOC stock changes under different residue management practices and conversion periods following ...

Coccolithophore particulate inorganic and organic carbon ratios: An evaluation of acid decalcification methods

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Physiology and Transcriptomics Reveal Divergent Strategies of Mycorrhiza‐Mediated Drought Adaptation in Poplar

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Mycorrhizal symbiosis shapes plant growth and stress resilience. Here, we compared physiological and molecular responses of poplars (P. x canescens) colonised by Paxillus involutus (Pi) or Cenococcum geophilum (Cg) under control conditions, drought stress and recovery.

Acetanilide herbicide exposure and lymphoid malignancy risk in the French AGRiculture and CANcer cohort

open access: yesEnvironment International
Many studies have reported an elevated risk of specific cancers including lymphoid malignancies (LM) in farmers, particularly those exposed to pesticides. Acetanilides are among the most widely sold herbicides in France. This study evaluated the risk for

Synthesis and Evaluation of Aromatic Sulfonamide and Disulfonamide Derivatives as Dengue Virus NS3–NS5 Interaction Inhibitors

open access: yesChemMedChem, Volume 21, Issue 11, 15 June 2026.
A synthetic methodology for the preparation of asymmetric benzene‐1,4‐disulfonamides was developed and applied to generate potential anti‐dengue virus (DENV) compounds. Guided by computer‐assisted structural rationalization, we designed synthetically more accessible analogs with reduced toxicity that interact with the DENV NS5 domain, thereby ...

Comparative Molecular Field Analysis (CoMFA) for Thiotetrazole Alkynylacetanilides, a Non-Nucleoside Inhibitor of HIV-1 Double Mutant K103N/Y181C Reverse Transcriptase

open access: yesE-Journal of Chemistry, 2009
Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are allosteric inhibitors of the HIV-1 reverse transcriptase. HIV-1 resistance to nucleoside RT inhibitors such as AZT can arise through mutations in the coding region of RT.

Unravelling the Secret of Sulfur Confinement and High Sulfur Utilization in Hybrid Sulfur‐Carbons

open access: yesAdvanced Materials, Volume 38, Issue 34, 17 June 2026.
Thermal condensation of inverse vulcanized sulfur‐carbon hybrids enables a bottom‐up sulfur confinement strategy, in which a protective carbon phase is progressively constructed around sulfur species. The resulting carbon nanodomains covalently tether sulfur chains and stabilize radical intermediates. This integrated architecture effectively suppresses

Geographic Variation in Diving Behaviour and Skin Isotope Ratios of Northern Bottlenose Whales, Hyperoodon ampullatus

open access: yesEcology and Evolution, Volume 16, Issue 6, June 2026.
High‐resolution multi‐sensor tag data from northern bottlenose whale populations in the northeast and northwest Atlantic showed differences in resting and foraging time budgets and behaviour. Skin biopsy stable isotopes corroborated likely dietary differences. Variability between populations has far‐reaching relevance for ecology and conservation, with

The Elbe Estuary Microbiome Shifts With Salinity and Discharge and Depends on Fresh Organic Matter and Nutrient Availability

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Microbial diversity within the Elbe Estuary was found to be more strongly governed by seasonal variability, salinity, and discharge than by spatial heterogeneity. Oligohaline regions sustain high diversity, while nutrient and redox conditions drive functional shifts.

The Dangers of Acetanilid. [PDF]

open access: yesJAMA: The Journal of the American Medical Association, 1905
Dodge City, Kan., July 14, 1905. To the Editor: -I was walking along the street some months ago and overtook my venerable friend, the Methodist minister, who said "Doctor, I'm glad to see you. What is antikamnia?" I told him that it is a mixture of uncertain composition, used with greater or less success for the relief of pain; that its principal ...
