Outflow boundary conditions for 3D simulations of non-periodic blood flow and pressure fields in deformable arteries [PDF]

, 2010
The simulation of blood flow and pressure in arteries requires outflow boundary conditions that incorporate models of downstream domains. We previously described a coupled multidomain method to couple analytical models of the downstream domains with 3D ...

Influence of the arterial elastic component on the response to balloon angioplasty in femoral arteries of a healthy porcine model

Animal Models and Experimental Medicine, EarlyView.
This study evaluates the role of elastin in vascular response 28 days after balloon angioplasty using uncoated and paclitaxel‐coated balloons in a healthy porcine model. The results show higher elastin content in external femoral arteries, which is inversely correlated with vascular injury, inflammation, smooth muscle cell loss, proteoglycan and fibrin

Absence of right common carotid artery in a patient with common origin of the innominate artery and left common carotid artery

Journal of Vascular Surgery Cases and Innovative Techniques, 2020
A 50-year-old woman was referred to the noninvasive vascular laboratory for carotid artery evaluation because of a bruit in the neck. Color Doppler ultrasound examination demonstrated absence of the right common carotid artery and parallel internal and ...

Variations in branching pattern of external carotid artery in a black Kenyan population [PDF]

, 2016
Knowledge of variations in branching of external carotid artery is important to minimise inadvertent injury and confusion in identification during neck and craniofacial surgery and interventional neuroradiology.

Development of the occipitopetrosal junctions: A histological study using human fetuses

The Anatomical Record, EarlyView.
Abstract The temporal bone petrosa is connected to the occipital bone at two sites: one junction with the basilar part (medial junction) and another with the lateral part (lateral junction). Using histological specimens from 45 human fetuses (approximately 7–39 weeks of gestational age or GA), we aimed to describe possible changes in histology and ...

Ketebalan Tunika Intima dan Media Arteri Karotis Komunis pada Karsinoma Nasofaring Pra dan Pascaradioterapi

Majalah Kedokteran Bandung, 2012
External radiotherapy is the main treatment for nasopharyngeal carcinoma. External radiotherapy can cause endothelial dysfunction of common carotid artery and reduces nitrogen oxide and prostacyclin by endothelial cell and cause thickening of the ...

Metformin for non-diabetic patients with coronary heart disease (the CAMERA study): a randomised controlled trial [PDF]

, 2009
<br>Background: Metformin reduces cardiovascular risk in patients with type 2 diabetes seemingly independent of lowering blood glucose concentration. We assessed the cardiovascular effects of metformin in individuals without type 2 diabetes.</br&

3D‐cultured BMSC exosomes improve cerebral ischemia/reperfusion injury‐induced neuronal apoptosis by regulating the microglia polarization

BMEMat, EarlyView.
The study reveals that microglial activation significantly contributes to neuroinflammation following cerebral ischemia‐reperfusion injury. It demonstrates that utilizing GelMA hydrogel for three‐dimensional culture of bone marrow‐derived mesenchymal stem cells (BMSCs) enhances the efficacy of BMSC‐derived exosomes in regulating microglial polarization
