Inverse association of circulating SIRT1 and adiposity. A study on underweight, normal weight, and obese patients [PDF]

, 2018
Context: Sirtuins (SIRTs) are NAD+-dependent deacetylases, cellular sensors to detect energy availability, and modulate metabolic processes. SIRT1, the most studied family member, influences a number of tissues including adipose tissue.

Survival of red blood cells after transfusion: processes and consequences

Frontiers in Physiology, 2013
The currently available data suggest that efforts towards improving the quality of red blood cell (RBC) blood bank products should concentrate on: (1) preventing the removal of a considerable fraction of the transfused RBCs that takes place within the ...

An overview about erythrocyte membrane [PDF]

, 2010
© 2010 – IOS Press and the authors. All rights reservedIn the sixties and seventies, erythrocytes or red blood cells (RBCs) were extensively studied. Much has been learnt particularly concerning their metabolism and gas transporter function. In the past

Levels of erythrocyte superoxide dismutase activity in Japanese people [PDF]

, 1978
Levels of erythrocyte superoxide dismutase (SOD) activitiy in a sample of Japanese people were determined. Blood samples were taken from new-born infants, preschool children, young and old people who had no apparent diseases and also from three anemic ...

Physiologically aged red blood cells undergo erythrophagocytosis in vivo but not in vitro

Haematologica, 2012
Background The lifespan of red blood cells is terminated when macrophages remove senescent red blood cells by erythrophagocytosis. This puts macrophages at the center of systemic iron recycling in addition to their functions in tissue remodeling and ...

Intracellular Ca2+ Concentration and Phosphatidylserine Exposure in Healthy Human Erythrocytes in Dependence on in vivo Cell Age

Frontiers in Physiology, 2020
After about 120 days of circulation in the blood stream, erythrocytes are cleared by macrophages in the spleen and the liver. The “eat me” signal of this event is thought to be the translocation of phosphatidylserine from the inner to the outer membrane ...

G-CSF Prevents the Progression of Structural Disintegration of White Matter Tracts in Amyotrophic Lateral Sclerosis: A Pilot Trial [PDF]

, 2011
Background: The hematopoietic protein Granulocyte-colony stimulating factor (G-CSF) has neuroprotective and regenerative properties. The G-CSF receptor is expressed by motoneurons, and G-CSF protects cultured motoneuronal cells from apoptosis.

Associations between dietary n-6 and n-3 fatty acids and arachidonic acid compositions in plasma and erythrocytes in young and elderly Japanese volunteers

Lipids in Health and Disease, 2011
Background We reported that the compositions of arachidonic acid (ARA) in erythrocytes and plasma phospholipids (PL) in the elderly were lower than those in the young, though the ARA intake was nearly identical. Objective We further analyzed data in four

Erythrocyte's aging in microgravity highlights how environmental stimuli shape metabolism and morphology [PDF]

, 2018
The determination of the function of cells in zero-gravity conditions is a subject of interest in many different research fields. Due to their metabolic unicity, the characterization of the behaviour of erythrocytes maintained in prolonged microgravity ...
