Tratamento Endovascular de Aneurismas da Aorta e Transfusão de Sangue. O que Precisamos? [PDF]

Acta Médica Portuguesa, 2016
INTRODUCTION: Comparatively to open repair, endovascular aneurysm repair has reduced transfusion rates but thereâs no recommendation about number of red blood cells units to be crossmatched preoperatively.

Mechanism of faster NO scavenging by older stored red blood cells [PDF]

Redox Biology, 2014
The blood storage lesion involves morphological and biochemical changes of red blood cells (RBCs) that occur during storage. These include conversion of the biconcave disc morphology to a spherical one, decreased mean corpuscular hemoglobin concentration,

Red blood cells and other non-spherical capsules in shear flow: oscillatory dynamics and the tank-treading-to-tumbling transition [PDF]

, 2006
We consider the motion of red blood cells and other non-spherical microcapsules dilutely suspended in a simple shear flow. Our analysis indicates that depending on the viscosity, membrane elasticity, geometry and shear rate, the particle exhibits either ...

New-Generation Ektacytometry Study of Red Blood Cells in Different Hemoglobinopathies and Thalassemia

Thalassemia Reports, 2023
Next-generation ektacytometry provided by the osmoscan module of the Laser Optical Rotational Red Cell Analyser (LoRRca) MaxSis is, so far, one of the best complementary diagnostic tools for congenital rare anaemias due to red blood cell defects. Osmotic

AlphaFold2 Update and Perspectives

BioMedInformatics, 2023
Access to the three-dimensional (3D) structural information of macromolecules is of major interest in both fundamental and applied research. Obtaining this experimental data can be complex, time consuming, and costly.

Analysis of the impact of handling and culture on the expansion and functionality of NK cells

Frontiers in Immunology, 2023
Natural killer (NK) cells are lymphocytes of the innate immune system that play a key role in the elimination of tumor and virus-infected cells. Unlike T cells, NK cell activation is governed by their direct interaction with target cells via the ...

Urinary diagnostic cytology beyond the research of neoplastic cells: Usefulness of erythrocyte morphology evaluation to recognize microhematuria source

Journal of Cytology, 2023
Background: Urine cytology is useful to diagnose urinary neoplasms, whereas its role in the study of microhematuria is debatable. Usually, standard urinalysis (dipstick test and sediment examination with bright field microscope) detects the presence of ...

The role of corticosterone in the regulation of the cellular composition of chicken blood during the stress reaction [PDF]

E3S Web of Conferences, 2021
The influence of hen layer density on the variability of the number of red blood cells, heterophiles and lymphocytes in the blood, the secretory activity of adrenal glands, estimated by the level of corti-costerone and cortisol, as well as the presence ...

Oxidative stress-induced DNA damage and repair in human peripheral blood mononuclear cells: protective role of hemoglobin. [PDF]

PLoS ONE, 2013
BACKGROUND:DNA repair is a cellular defence mechanism responding to DNA damage caused in large part by oxidative stress. There is a controversy with regard to the effect of red blood cells on DNA damage and cellular response.
