Endothelial BMP6 Drives Hemodynamic‐Dependent VSMCs Calcification in Carotid Atherosclerosis

open access: yesAdvanced Science, Volume 13, Issue 2, 9 January 2026.
The study demonstrates that endothelial cell (EC)‐derived BMP6 promotes the osteogenic differentiation of vascular smooth muscle cells (VSMCs) through cell‐cell interactions. Additionally, the researchers preliminarily explore the driving effect of hemodynamic factors on BMP6‐induced calcification and reveal the regulatory role of KLF4 on BMP6.

Assessment of crystallographic orientation effects on secondary ion mass spectrometry (SIMS) analysis of cassiterite [PDF]

open access: yes, 2017
Crystallographic orientation effects on ion microprobe analyses for U-Pb and O-isotopes have been reported for a number of oxide minerals, including rutile (TiO₂) and baddeleyite (ZrO₂).

New U-Pb zircon ages of El Baúl Massif, Cojedes State, Venezuela

open access: yesRevista Técnica de la Facultad de Ingeniería
El Baúl massif (Cojedes State, Venezuela) has been studied since 1858, especially as an important target for oil companies since it is a structural high that has played an important role in the evolution of the oil bearing Barinas-Apure and Eastern ...

SHRIMP U–Pb–Th xenotime (YPO₄ ) geochronology: A novel approach for the correction of SIMS matrix effects [PDF]

open access: yes, 2017
Xenotime (YPO4) occurs in a wide range of geological environments, but its potential to establish the timing of mineralisation and sediment diagenesis has been the focus of most recent studies.

Timing of eclogite-facies metamorphism of the Chuacús complex, Central Guatemala: Record of Late Cretaceous continental subduction of North America's sialic basement [PDF]

open access: yes, 2012
A Late Cretaceous collision of the southernmost portion of the North American continental margin with an undetermined southern block was first established based on the sedimentation history of the plate's supracrustal cover, which is overthrust by ...

Shocked Quartz in Polymict Impact Breccia from the Upper Cretaceous Yallalie Impact Structure in Western Australia [PDF]

open access: yes
Yallalie is a ~12 km diameter circular structure located ~200 km north of Perth, Australia. Previous studies have proposed that the buried structure is a complex impact crater based on geophysical data.

Implicaciones genéticas de nuevos datos de Sr y Nd de rocas intrusivas del Arco Laramide en el Norte de Sonora, México [PDF]

open access: yes
The Laramide Intrusive Arc constitutes a wide intrusive belt broadly parallel to the actual Sonora coastline. It was formed by the subduction of the Farallon Plate beneath the North-American Plate during the Late Cretaceous-Early Tertiary period.

Coupled Nd-142, Nd-143 and Hf-176 Isotopic Data from 3.6-3.9 Ga Rocks: New Constraints on the Timing of Early Terrestrial Chemical Reservoirs [PDF]

open access: yes
Increasingly precise data from a range of isotopic decay schemes, including now extinct parent isotopes, from samples of the Earth, Mars, Moon and meteorites are rapidly revising our views of early planetary differentiation.

Pacific subduction coeval with the Karoo mantle plume : the early Jurassic subcordilleran belt of northwestern Patagonia [PDF]

open access: yes, 2005
The Early Mesozoic magmatism of southwestern Gondwana is reviewed in the light of new U-Pb SHRIMP zircon ages (181 ± 2 Ma, 181 ± 3 Ma, 185 ± 2 Ma, and 182 ± 2 Ma) that establish an Early Jurassic age for the granites of the Subcordilleran plutonic belt ...
