Processes and Patterns of Dolomite Precipitation in Aptian Pre‐Salt Deposits of Santos Basin, Brazil

Journal of Petroleum Geology, EarlyView.
ABSTRACT The Aptian pre‐salt lacustrine carbonates represent the most significant oil exploration target along the South Atlantic margin. Dolomitization of the Santos Basin Barra Velha Formation (BVF) is critical for reservoir quality, yet its origin, patterns, and evolution remain poorly understood.

Periodontitis and Diabetes: Mechanistic Evidence of a Circular Relationship

Journal of Periodontal Research, EarlyView.
This narrative review aimed to explore the underlying mechanisms that connect periodontitis to diabetes (and vice versa) and that influence disease susceptibility, progression and response to treatment. ABSTRACT The circular relationship between periodontitis and diabetes mellitus is one of the most established oral‐systemic links.

Neurite Imaging Reveals Widespread Alterations in Grey Matter Neurite Morphology in Obstructive Sleep Apnoea

Journal of Sleep Research, EarlyView.
ABSTRACT Obstructive sleep apnoea (OSA) is a common chronic multisystem disorder, and cortical structural alterations have been detected via conventional neuroimaging techniques. Recent advances in diffusion‐weighted imaging have yielded novel techniques for investigating neural microstructure, which may potentially offer supplementary insights into ...

Revisiting olivine‐phyric shergottites: Pyroxene crystallization pressure and the role of undercooling

Meteoritics &Planetary Science, EarlyView.
Abstract Shergottites are the most abundant meteorites from Mars and a major source of information on magma reservoirs, transport, and eruption, particularly in the late Hesperian northern hemisphere. Conflicting interpretations have arisen on the crystallization conditions of pyroxene in olivine‐phyric shergottites.
