Constraints on Element Mobility During Deformation Within the Seismogenic Zone, Shimanto Belt, Japan

open access: yesGeochemistry, Geophysics, Geosystems, 2021
Subduction interfaces exhibit a variety of slip behaviors, including megathrust and slow earthquakes. Field observations are consistent with crack‐seal deformation, in which tensile cracks are sealed by fluid‐transported solute.

Blood flow-induced Notch activation and endothelial migration enable vascular remodeling in zebrafish embryos. [PDF]

open access: yes, 2018
Arteries and veins are formed independently by different types of endothelial cells (ECs). In vascular remodeling, arteries and veins become connected and some arteries become veins. It is unclear how ECs in transforming vessels change their type and how

Spontaneous initiation of atrial fibrillation by ectopic beats originating in the pulmonary veins.

open access: yesNew England Journal of Medicine, 1998
BACKGROUND Atrial fibrillation, the most common sustained cardiac arrhythmia and a major cause of stroke, results from simultaneous reentrant wavelets. Its spontaneous initiation has not been studied.

Using a novel source-localized phase regressor technique for evaluation of the vascular contribution to semantic category area localization in BOLD fMRI. [PDF]

open access: yes, 2015
Numerous studies have shown that gradient-echo blood oxygen level dependent (BOLD) fMRI is biased toward large draining veins. However, the impact of this large vein bias on the localization and characterization of semantic category areas has not been ...

Culture of human endothelial cells derived from umbilical veins. Identification by morphologic and immunologic criteria.

open access: yesJournal of Clinical Investigation, 1973
Endothelial cells were isolated from freshly obtained human umbilical cords by collagenase digestion of the interior of the umbilical vein. The cells were grown in tissue culture as a homogeneous population for periods up to 5 mo and some lines were ...

Transvenous Embolization of Cavernous Sinus Dural Arteriovenous Fistula Using the Direct Superior Ophthalmic Vein Approach: A Case Report [PDF]

open access: yesNeurointervention, 2011
Transvenous coil embolization has been successfully applied for the treatment of cavernous sinus dural arteriovenous fistula (CSDAVF). Unfortunately, the technique cannot be applied in cases of poor or absent inferior petrosal sinus or facial venous ...

Cartilaginous metaplasia of varicose veins: a case report [PDF]

open access: yes, 2013
Cartilaginous metaplasia of superficial veins was found in a 64-year-old woman who underwent surgery for varicose veins. At operation, some varicose veins of the medial thigh were semi-rigid and fibroelastic to the touch. Histology revealed that half the

Remodeling of macular vortex veins in pachychoroid neovasculopathy

open access: yesScientific Reports, 2019
Superior and inferior macular vortex veins are divided by a horizontal watershed passing through the macula. We evaluated macular vortex vein remodeling in eyes with pachychoroid neovasculopathy (PNV).
