Aging in Normotensive and Spontaneously Hypertensive Rats: Focus on Erythrocyte Properties

Biology, 2023
Erythrocyte deformability, crucial for oxygen delivery to tissues, plays an important role in the etiology of various diseases. As the factor maintaining the erythrocyte deformability, nitric oxide (NO) has been identified.

A preliminary study of phosphodiesterases and adenylyl cyclase signaling pathway on red blood cell deformability of sickle cell patients

Frontiers in Physiology, 2023
Sickle cell disease (SCD) is an inherited hemoglobinopathy characterized by chronic anemia, intravascular hemolysis, and the occurrence of vaso-occlusive crises due to the mechanical obstruction of the microcirculation by poorly deformable red blood ...

Deformability-Based Isolation of Circulating Tumor Cells in Spiral Microchannels

Micromachines, 2023
The isolation of circulating tumor cells (CTCs) and their analysis are crucial for the preliminary identification of invasive cancer. One of the effective properties that can be utilized to isolate CTCs is their deformability.

q-Deformed and c-Deformed Harmonic Oscillators [PDF]

Progress of Theoretical Physics, 2003
Summary: Hamilton functions of classical deformed oscillators (\(c\)-deformed oscillators) are derived from Hamiltonians of \(q\)-deformed oscillators of the Macfarlane and Dubna types. A new scale parameter, \(l_q\), with the dimension of length, is introduced to relate a dimensionless parameter characterizing the deformation with the natural length ...

Classifying deformable and non-deformable video objects [PDF]

7th International Conference on Imaging for Crime Detection and Prevention (ICDP 2016), 2016
This paper presents a fully automated approach to classifying deformable and non-deformable moving objects in a video surveillance scene. We estimate an object's motion using Marzat optical-flow algorithm. We filter the motion vectors and attempt to find the transformation that represents the correct mapping between the two positions.

Quantifying Deformation and Migration Properties of U87 Glioma Cells Using Dielectrophoretic Forces

Biosensors, 2022
Glioblastoma multiforme is one of the most aggressive malignant primary brain tumors. To design effective treatment strategies, we need to better understand the behavior of glioma cells while maintaining their genetic and phenotypic stability.

On the Effects of Reactive Oxygen Species and Nitric Oxide on Red Blood Cell Deformability

Frontiers in Physiology, 2018
The main function of red blood cells (RBCs) is the transport of respiratory gases along the vascular tree. To fulfill their task, RBCs are able to elastically deform in response to mechanical forces and, pass through the narrow vessels of the ...

P5 ERYTHROCYTE DEFORMABILITY AND NITRIC OXIDE PRODUCTION IN ANIMAL MODEL OF PRIMARY HYPERTENSION AND THEIR AGE-DEPENDENT CHANGES

Artery Research, 2017
Objectives: Reduced deformability of red blood cells (RBC) plays an important role in etiology of various diseases including cardiovascular. The nitric oxide (NO) was identified as one of factors responsible for maintenance of RBC deformability.

Influence of addition of shredded rubber waste on deformability of binder-bound anthropogenic material mixtures [PDF]

Archives of Civil Engineering, 2021
Construction is one of the industrial sectors responsible for the use of large quantities of natural raw materials. This fact makes it necessary to look for new technologies of producing construction materials based as much as possible on waste materials.
