Changes in the Conformational State of Hemoglobin in Hemodialysed Patients with Chronic Renal Failure [PDF]

open access: yes, 2015
The aim of this study was to evaluate the properties of internal components of erythrocytes in chronic renal failure (CRF) patients undergoing hemodialysis (HD) in comparison to control subjects.

DELP Treatment on Vision and Retinal Microcirculation in Patients With Acute Ischemic Stroke: Report of Five Cases and Literature Review

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background The delipid extracorporeal lipoprotein filter from plasma (DELP) treatment can effectively reduce blood lipid, increase blood flow, and improve neurological deficits in patients with acute ischemic stroke (AIS). However, its effect on vision and retinal microcirculation in stroke patients has never been reported.

A Comparative Study of Cerebral Oxygenation During Exercise in Hemodialysis and Peritoneal Dialysis Patients

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Introduction Cognitive impairment and exercise intolerance are common in dialysis patients. Cerebral perfusion and oxygenation play a major role in both cognitive function and exercise execution; HD session per se aggravates cerebral ischemia in this population. This study aimed to compare cerebral oxygenation and perfusion at rest and in mild

A Modification of the Spectrophotometric Method for Determining Oxyhemoglobin Affinity [PDF]

open access: yes, 1972
The role of hemoglobin as a carrier of oxygen in the blood was established in 1859 by Hoppe-Seyler. Bert, using whole blood, furnished experimental data whereby an oxyhemoglobin affinity curve could be plotted. In 1886, C. Bohr published data on purified

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Hemoglobin promotes Staphylococcus aureus nasal colonization.

open access: yesPLoS Pathogens, 2011
Staphylococcus aureus nasal colonization is an important risk factor for community and nosocomial infection. Despite the importance of S. aureus to human health, molecular mechanisms and host factors influencing nasal colonization are not well understood.

Aggregation of hemoglobin S and hemoglobin CHarlem with nonsickle hemoglobin in concentrated phosphate buffer [PDF]

open access: yesBlood, 1980
Abstract The effect of HbA and HbF on both the aggregation and deaggregation of deoxy HbS and deoxy HbCHarlem in concentrated phosphate buffers was studied by a turbidimetric method. Although pure deoxy HbA is fully soluble in 2.4 M potassium phosphate buffer, the same concentration of deoxy HbAS was insoluble in the same buffer.

Studies on the Hemoglobin of Cooley's Anemia and Cooley's Trait [PDF]

open access: yes, 1952
The diseases sickle cell anemia and Cooley's anemia (also known as thalassemia or Mediterranean anemia) have associated with them "minor" or "trait" forms of the disease in which the symptomatology is minimal, and the abnormalities in the red cells are ...

Following red blood cells in a pulmonary capillary [PDF]

open access: yes, 2007
The red blood cells or erythrocytes are biconcave shaped cells and consist mostly in a membrane delimiting a cytosol with a high concentration in hemoglobin.

Adaptaquin is selectively toxic to glioma stem cells through disruption of iron and cholesterol metabolism

open access: yesMolecular Oncology, EarlyView.
Adaptaquin selectively kills glioma stem cells while sparing differentiated brain cells. Transcriptomic and proteomic analyses show Adaptaquin disrupts iron and cholesterol homeostasis, with iron chelation amplifying cytotoxicity via cholesterol depletion, mitochondrial dysfunction, and elevated reactive oxygen species.
