Nimodipine augments cerebrovascular reactivity in aging but runs the risk of local perfusion reduction in acute cerebral ischemia

Frontiers in Aging Neuroscience, 2023
IntroductionThe efficacy of cerebrovascular reactivity (CVR) is taken as an indicator of cerebrovascular health.Methods and ResultsWe found that CVR tested with the inhalation of 10 % CO2 declined in the parietal cortex of 18-20-month-old rats.

Evaluation of aberrant expression of CD markers in acute leukemia cells

Zanco Journal of Medical Sciences, 2023
Background and objective: Worldwide immunophenotyping by flow cytometry (FCM) in acute leukemia (AL) is the golden step in the diagnosis. It’s very common for acute leukemias to aberrantly express antigens or cluster of differentiation (CD) markers which

Investigation of spiral blood flow in a model of arterial stenosis [PDF]

, 2009
The spiral component of blood flow has both beneficial and detrimental effects in human circulatory system [Stonebridge PA, Brophy CM. Spiral laminar flow in arteries? Lancet 1991; 338: 1360–1].

Large-Eddy simulation of pulsatile blood flow [PDF]

, 2009
Large-Eddy simulation (LES) is performed to study pulsatile blood flow through a 3D model of arterial stenosis. The model is chosen as a simple channel with a biological type stenosis formed on the top wall.

Immune cell phenotyping in low blood volumes for assessment of cardiovascular disease risk, development, and progression: a pilot study

Journal of Translational Medicine, 2020
Background Cardiovascular disease (CVD) is the leading cause of death in the world. Given the role of immune cells in atherosclerosis development and progression, effective methods for characterizing immune cell populations are needed, particularly among

Expression of circular RNAs in myelodysplastic neoplasms and their association with mutations in the splicing factor gene SF3B1

Molecular Oncology, 2023
Mutations in the splicing factor 3b subunit 1 (SF3B1) gene are frequent in myelodysplastic neoplasms (MDS). Because the splicing process is involved in the production of circular RNAs (circRNAs), we investigated the impact of SF3B1 mutations on circRNA ...

Blood flow and microgravity

Comptes Rendus. Mécanique, 2016
AbstractThe absence of gravity during space flight can alter cardio-vascular functions partially due to reduced physical activity. This affects the overall hemodynamics, and in particular the level of shear stresses to which blood vessels are submitted.

Blood Flow Restriction Exercise: Considerations of Methodology, Application, and Safety

Frontiers in Physiology, 2019
The current manuscript sets out a series of guidelines for blood flow restriction exercise, focusing on the methodology, application and safety of this mode of training. With the emergence of this technique and the wide variety of applications within the

TIGIT-positive circulating follicular helper T cells display robust B-cell help functions: potential role in sickle cell alloimmunization

Haematologica, 2015
T follicular helper cells are the main CD4+ T cells specialized in supporting B-cell responses, but their role in driving transfusion-associated alloimmunization is not fully characterized.
