Five‐Year Success of Endodontics Plus Vital Pulp Therapy in a Symptomatic Maxillary Molar: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT This case report details the integration of nonsurgical endodontic treatment (NSET) and vital pulp therapy (VPT) for symptomatic irreversible pulpitis (SIP) and symptomatic apical periodontitis (SAP) in a mature maxillary molar, with 5‐year follow‐up.

A comparative study of low‐temperature carbonate formation on natural exopolymers from hypersaline microbial mats and clay minerals

The Depositional Record, Volume 12, Issue 3, June 2026.
The data collected during these experiments have shown that carbonates preferentially nucleate on EPS most likely on carboxylic functional groups. The confirmation of preferential nucleation of carbonates on carboxylic groups lends credence to the currently proposed organomineralisation model of low‐T dolomite precipitation.

U/Th dating of cold-seep carbonates: An initial comparison

, 2010
Authigenic carbonates from hydrocarbon seeps are unique archives of past seepage and associated environmental parameters. In order to constrain the ages of a set of seep carbonates and the time involved in carbonate formation, we applied Uranium/Thorium (

Upland Afforestation Desiccates Downslope Wetlands on Sandy Soil

Ecohydrology, Volume 19, Issue 4, June 2026.
ABSTRACT Afforestation of formerly open, water‐limited habitats is a globally widespread form of land conversion, driven by the need for timber and non‐timber forest products, and capturing atmospheric carbon. However, increased tree cover can adversely affect hydrological cycles by increasing evapotranspiration and reducing downslope water yield ...

Cold seep communities and gas hydrates.

, 2013
Distribution of cold seep faunal communities (black crosses, regions as in Figure 1) on the Hikurangi Margin in relation to occurrence of bottom simulating reflectors (BSR) in seismic survey data and sites of potential interest for gas hydrate ...

Climatic, lithologic and topographic control on alpine rock fracturing and talus evolution

Earth Surface Processes and Landforms, Volume 51, Issue 6, June 2026.
Investigating Holocene rockwall–talus systems in an Alpine valley revealed that lithologic and topographic conditions in concert with climatic‐driven stresses and time since deglaciation result in rockwall fracture patterns that control rockfall size, erosion rates and the characteristics and evolution of talus.

Karst Vadose Zone Hydrology Explored Through Cave Drip Water Dynamics: The Roles of Soil, Epikarst and Climate

Hydrological Processes, Volume 40, Issue 6, June 2026.
Cave drip rate monitoring in Nova Grgosova Cave reveals three types of drip sites: (1) predominantly constant, (2) seasonally varying and (3) mostly constant with occasional sharp increases. The observational data coupled with one‐dimensional water‐balance model demonstrates that evapotranspiration and soil–epikarst storage, rather than precipitation ...

Natural Structural Transition of Gas Hydrates From sI to sII in the Deep Seafloor

Geophysical Research Letters
The evolution of gas hydrates influenced by the seawater environment is unknown. We present a model of structural transformation from sI hydrate to sII hydrate due to the influence of seawater environment and vent fluid in nature through in situ ...

Harnessing Trace Elements: Novel Radiosensitization Strategies for Enhanced Cancer Radiotherapy

Rare Metals, Volume 45, Issue 6, June 2026.
ABSTRACT Radiotherapy (RT) is one of the core methods of comprehensive cancer treatment. Globally, more than 40% of cancer patients rely on radiotherapy to achieve tumor control, cure or palliative relief. However, radiation resistance, immunosuppression and normal tissue injury limit its clinical application.

Dissolved Organic Matter (DOM) Dynamics at the Sediment‐Water Interface in the North Sea: Implications for Global Benthic DOM Fluxes

Global Biogeochemical Cycles, Volume 40, Issue 6, June 2026.
Abstract Sediment–water exchange of dissolved organic matter (DOM) represents a critical yet poorly constrained component of the marine carbon cycle. Here, we combine quantitative, molecular, and carbon isotope (δ13C and F14C) analyses to investigate the production, composition, and export of porewater DOM in the German Bight, North Sea, and evaluate ...
