Forms of pseudotuberculosis progression in children and the impact of lipid peroxidation activation and antioxidant system imbalance on their development

Журнал инфектологии, 2021
The objective is to compare clinical symptoms, lipid peroxidation indicators, the state of the antioxidant system and assess their impact on the severity and progression of pseudotuberculosis in children.Materials and methods.

On the Shape of the Erythrocyte

Biophysical Journal, 1968
A model is postulated which attributes the distinctive biconcave shape of the human erythrocyte to a balance of forces acting on the membrane. The forces considered are electrostatic forces due to a charge distribution on the membrane, a hydrostatic pressure difference acting across the membrane, and forces arising from a constant tension in the ...

Plasmodium falciparum ligand binding to erythrocytes induce alterations in deformability essential for invasion [PDF]

, 2017
The most lethal form of malaria in humans is caused by Plasmodium falciparum. These parasites invade erythrocytes, a complex process involving multiple ligand-receptor interactions.

Effect of Thioridazine on Erythrocytes [PDF]

Toxins, 2013
Background: Thioridazine, a neuroleptic phenothiazine with antimicrobial efficacy is known to trigger anemia. At least in theory, the anemia could result from stimulation of suicidal erythrocyte death or eryptosis, which is characterized by cell shrinkage and by phospholipid scrambling of the cell membrane with phosphatidylserine exposure at the ...

Physical and chemical processes and the morphofunctional characteristics of human erythrocytes in hyperglycaemia [PDF]

, 2017
Background: This study examines the effect of graduated hyperglycaemia on the state and oxygen-binding ability of hemoglobin, the correlation of phospholipid fractions and their metabolites in the membrane, the activity of proteolytic enzymes and the ...

Interactions Between Aerolysin, Erythrocytes, and Erythrocyte Membranes [PDF]

Infection and Immunity, 1975
Aerolysin, a hemolytic and lethal exotoxin of Aeromonas hydrophila , was analyzed for amino acids. Assuming 8 histidine residues/mol, the purified toxic protein has, by summation, a molecular weight of 49,000, a value in agreement with earlier estimates by other methods.

Diseased Erythrocyte Enrichment Based on I-Shaped Pillar DLD Arrays

Micromachines
Enrichment of erythrocytes is a necessary step in the diagnosis of blood diseases. Due to the high deformability and viscosity of erythrocytes, they cannot be regarded as stable point-like solids, so the influence of their deformability on fluid dynamics

Lipooligosaccharides (LOS) of Neisseria gonorrhoeae and Neisseria meningitidis have components that are immunochemically similar to precursors of human blood group antigens. Carbohydrate sequence specificity of the mouse monoclonal antibodies that recognize crossreacting antigens on LOS and human erythrocytes. [PDF]

, 1988
We have used mouse mAbs, 3F11 and 06B4, that are specific for highly conserved epitopes of Neisseria gonorrhoeae lipooligosaccharides (LOS) to identify immunochemically similar structures on human erythrocytes. mAb 3F11 agglutinated erythrocytes from all

Optical tweezer for probing erythrocyte membrane deformability

, 2009
We report that the average rotation speed of optically trapped crenated erythrocytes is direct signature of their membrane deformability. When placed in hypertonic buffer, discocytic erythrocytes are subjected to crenation.

Plasmodium falciparum gametogenesis essential protein 1 (GEP1) is a transmission‐blocking target

FEBS Letters, EarlyView.
This study shows Plasmodium falciparum GEP1 is vital for activating sexual stages of malarial parasites even independently of a mosquito factor. Knockout parasites completely fail gamete formation even when a phosphodiesterase inhibitor is added. Two single‐nucleotide polymorphisms (V241L and S263P) are found in 12%–20% of field samples.
