Carotid Intima-Media Thickness Progression in HIV-Infected Adults Occurs Preferentially at the Carotid Bifurcation and Is Predicted by Inflammation. [PDF]

, 2012
BackgroundShear stress gradients and inflammation have been causally associated with atherosclerosis development in carotid bifurcation regions. The mechanism underlying higher levels of carotid intima-media thickness observed among HIV-infected ...

Hot‐Film and Calorimetric Methods With Transient Heating for Measurement of High Biofluid Flow Rate

Advanced Functional Materials, EarlyView.
Accurate measurement of biofluid flow rate is vital for clinical diagnostics. We propose a transient heating strategy using short thermal pulses and peak temperature tracking to enhance the flow sensitivity of the hot‐Film and calorimetric methods. Simulations show how optimal heating time maximizes sensitivity across flow rates.

A systematic study of the brain base arteries in the rabbit (Oryctolagus cuniculus)

Pesquisa Veterinária Brasileira, 2013
The brains of 30 New Zealand rabbits (Oryctolagus cuniculus) were injected with red stained latex. The arteries of the ventral surface of the brain were systematized on the right (R) and on the left (L) side with the respective percentage of appearance ...

Angioarchitectural evolution of clival dural arteriovenous fistulas in two patients. [PDF]

, 2015
Dural arteriovenous fistulas (dAVFs) may present in a variety of ways, including as carotid-cavernous sinus fistulas. The ophthalmologic sequelae of carotid-cavernous sinus fistulas are known and recognizable, but less commonly seen is the rare clival ...

Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

Advanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Occlusion of Internal Carotid Artery in Kimura's Disease

Case Reports in Medicine, 2010
We describe a unique case of Kimura's disease in which cerebral infarction was caused by occlusion of the right internal carotid artery. A 25-year-old man with Kimura's disease was admitted to our hospital because of left hemiparesis. Computed tomography

Elastomeric Micro‐Balloons for Remote Control of Cerebral Blood Flow and Real‐Time In vivo Imaging of Rodent Brain Response to Hypoperfusion

Advanced Materials, EarlyView.
This study reports the fabrication of MRI‐compatible elastomeric micro‐balloons via a multi‐step bubble casting process, where the monolithic elastomeric wall is selectively stiffened for reversible and controlled inflation and elasticity, depending on the target vessels for graded occlusion of cerebral arteries.

Genetic susceptibility loci for cardiovascular disease and their impact on atherosclerotic plaques [PDF]

, 2018
Background: Atherosclerosis is a chronic inflammatory disease in part caused by lipid uptake in the vascular wall, but the exact underlying mechanisms leading to acute myocardial infarction and stroke remain poorly understood. Large consortia identified

Agenesis of the internal carotid artery.

Jornal vascular brasileiro, 2018
Agenesis of the internal carotid artery is a rare anomaly. It is usually asymptomatic because of the presence of anastomoses, but it can be associated with complications, especially when there is evidence of other anatomical abnormalities or severe atherosclerotic disease.
