Giant serpentine aneurysm [PDF]
BMJ Case Reports, 2016 A 34-year-old man with a history of seizures presented after a generalised seizure. An MRI of the brain and MR angiogram of the brain (figure 1) were performed, demonstrating a partially thrombosed, giant intracranial aneurysm involving the left anterior cerebral artery (ACA).

, 1992 Palladium, platinum, and gold were analyzed for 20 interstitial water samples from Leg 125. No Pd or Pt was detected in fluids from serpentinite muds from Conical Seamount in the Mariana forearc, indicating that low-temperature seawater-peridotite ...

Constraints on Bend‐Faulting and Mantle Hydration at the Marianas Trench From Seismic Anisotropy
Geophysical Research Letters, 2023 Subduction zones are a key link between the surface water cycle and the solid Earth, as the incoming plate carries pore water and hydrous minerals into the subsurface.

Giant serpentine aneurysms [PDF]
Neurosurgical Focus, 2009 Segal and McLaurin first described giant serpentine aneurysms, based on their distinct angiographic features, in 1977. These lesions are ≥ 25 mm, partially thrombosed aneurysms with a patent, serpiginous vascular channel that courses through the aneurysm.

Hypotheses for near-surface exchange of methane on Mars [PDF]
, 2016 The Curiosity rover recently detected a background of 0.7 ppb and spikes of 7 ppb of methane on Mars. This in situ measurement reorients our understanding of the Martian environment and its potential for life, as the current theories do not entail any ...

Photochemical enrichment of deuterium in Titan's atmosphere: new insights from Cassini-Huygens [PDF]
, 2008 Cassini-Huygens data are used to re-examine the potential sources of the D/H enhancement over solar, measured in methane, in Titan's atmosphere. Assuming that the system is closed with respect to carbon, the use of constraints from the Huygens probe for ...

Native H2 Exploration in the Western Pyrenean Foothills
Geochemistry, Geophysics, Geosystems, 2021 Native hydrogen (H2) may represent a new carbon free‐energy resource, but to date there is no specific exploration guide to target H2‐fertile geological settings. Here, we present the first soil gas survey specifically designed to explore H2 migration in
