A New Strategy for the Morphological and Colorimetric Recognition of Erythrocytes for the Diagnosis of Forms of Anemia based on Microscopic Color Images of Blood Smears [PDF]

open access: yesInternational journal of advanced computer science and applications (IJACSA), 2020, 11 (7), pp.488-497, 2023
The detection of red blood cells based on morphology and colorimetric appearance is very important in improving hematology diagnostics. There are automatons capable of detecting certain forms, but these have limitations with regard to the formal identification of red blood cells because they consider certain cells to be red blood cells when they are ...

Characterization of a Putative Hemolysin Expressed by Sneathia amnii, a Preterm Birth-associated Pathogen [PDF]

open access: yes, 2017
The gram-negative bacteria Sneathia amnii is a poorly-characterized commensal of the female urogenital tract frequently associated with adverse clinical outcomes such as bacterial vaginosis (BV), amnionitis, and preterm labor.

Red blood cells estimation using Hough transform technique [PDF]

open access: yes, 2012
The number of red blood cells contributes more to clinical diagnosis with respect to blood diseases. The aim of this research is to produce a computer vision system that can detect and estimate the number of red blood cells in the blood sample image ...

Autophagy in cancer and protein conformational disorders

open access: yesFEBS Letters, EarlyView.
Autophagy plays a crucial role in numerous biological processes, including protein and organelle quality control, development, immunity, and metabolism. Hence, dysregulation or mutations in autophagy‐related genes have been implicated in a wide range of human diseases.

Clustered Red Blood Cells Splitting via Boundary Analysis in Microscopic Thin Blood Smear Digital Images

open access: yesInternational Journal of Technology, 2015
Clustered Red Blood Cells are observed very frequently in the thin blood smear digital images. Separating clustered Red Blood Cells from the single Red Blood Cells and splitting of clustered Red Blood Cells into single Red Blood Cells is a challenging

A micro-scale simulation of red blood cell passage through symmetric and asymmetric bifurcated vessels [PDF]

open access: yes, 2016
Blood exhibits a heterogeneous nature of hematocrit, velocity, and effective viscosity in microcapillaries. Microvascular bifurcations have a significant influence on the distribution of the blood cells and blood flow behavior. This paper presents a simulation study performed on the two-dimensionalmotions and deformation of multiple red blood cells in ...

Vortical flow structures induced by red blood cells in capillaries [PDF]

open access: yesarXiv, 2021
Knowledge about the flow field of the plasma around the red blood cells in capillary flow is important for a physical understanding of blood flow and the transport of micro- and nanoparticles and molecules in the flowing plasma. We conduct an experimental study on the flow field around red blood cells in capillary flow that are complemented by ...

Modifications in FLAP's second cytosolic loop influence 5‐LOX interaction, inhibitor binding, and leukotriene formation

open access: yesFEBS Letters, EarlyView.
The enzyme 5‐lipoxygenase (5‐LOX) catalyzes the first step in the biosynthesis of leukotrienes (LTs) involved in inflammatory pathophysiology. After cellular stimulation, 5‐LOX translocates to the nucleus, interacting with the 5‐LOX‐activating protein (FLAP) to form LTA4 from arachidonic acid (AA).

Production of hematopoietic cells from umbilical cord blood stem cells for transfusion purposes: Focus on ex vivo generation of red blood cells [PDF]

open access: yesScripta Medica, 2012
Cord blood contains a heterogeneous population of stem cells and progenitors and, in addition to transplantation these cells could be used also for ex vivo production of mature cells, as red blood cells (RBC).

Red blood cells contain enzymatically active GPx4 whose abundance anticorrelates with hemolysis during blood bank storage

open access: yesRedox Biology, 2021
The antioxidant function of the phospholipid hydroperoxide glutathione peroxidase (GPx4) is vital for the homeostasis of many cell types, from neoplastic cells to normal erythroid precursors.
