Force balance and membrane shedding at the Red Blood Cell surface [PDF]

, 2006
During the aging of the red-blood cell, or under conditions of extreme echinocytosis, membrane is shed from the cell plasma membrane in the form of nano-vesicles. We propose that this process is the result of the self-adaptation of the membrane surface area to the elastic stress imposed by the spectrin cytoskeleton, via the local buckling of membrane ...

Fractal Rigidity in Migraine [PDF]

, 2003
We study the middle cerebral artery blood flow velocity (MCAfv) in humans using transcranial Doppler ultrasonography (TCD). Scaling properties of time series of the axial flow velocity averaged over a cardiac beat interval may be characterized by two exponents. The short time scaling exponent (STSE) determines the statistical properties of fluctuations

Fluid structure interaction: Insights into biomechanical implications of endograft after thoracic endovascular aortic repair [PDF]

Computers in Biology and Medicine (2021), 2021
Thoracic endovascular aortic repair (TEVAR) has developed to be the most effective treatment for aortic diseases. This study aims to evaluate the biomechanical implications of the implanted endograft after TEVAR. We present a novel image-based, patient-specific, fluid-structure computational framework.

Anomalous angiogenesis in retina [PDF]

Biomedicines 9, 224 (2021), 2021
Age-related macular degeneration (AMD) may cause severe loss of vision or blindness particularly in elderly people. Exudative AMD is characterized by angiogenesis of blood vessels growing from underneath the macula, crossing the blood-retina barrier (that comprise Bruch's membrane, BM, and the retinal pigmentation epithelium RPE), leaking blood and ...

DNA Methylation of the ABO Promoter Underlies Loss of ABO Allelic Expression in a Significant Proportion of Leukemic Patients [PDF]

, 2009
Background: Loss of A, B and H antigens from the red blood cells of patients with myeloid malignancies is a frequent occurrence. Previously, we have reported alterations in ABH antigens on the red blood cells of 55% of patients with myeloid malignancies.

Analysis of the Effect of Atherosclerosis with the Changes of Hematocrit: A Computational Study on the Hemodynamics of Carotid Artery [PDF]

2020 2nd International Conference on Advanced Information and Communication Technology (ICAICT) (pp. 336-341). IEEE, 2021
Atherosclerosis is a state wherein plaque (fat, cholesterol, and different substances) develops inside the veins that in the end prompts carotid artery stenosis which is a phase of narrowing in the huge courses situated on either side of the neck that convey blood to the brain, face, and head.

Intraoperative blood loss and surgical time according to the direction of maxillary movement

Archives of Plastic Surgery, 2020
Background Excessive bleeding is one of the most severe complications of orthognathic surgery (OGS). This study investigated the associations of intraoperative blood loss and surgical time with the direction of maxillary movement.
