Nucleoside transport in sheep reticulocytes : evidence for an intracellular transporter pool

, 1992
We tested the existence of an intracellular nucleoside transporter pool in sheep reticulocytes. The number of cell surface NBMPR binding sites in sheep reticulocytes is 5.1 $ pm$ 0.5 (S.D.) fmol/10$ sp{6}$ cells (n = 9), compared to 6.9 $ pm$ 0.4 (S.D ...

Splenic Sequestration of Reticulocytes in the Rabbit

, 2009
The spleen appears to be the site for retaining immature erythrocytes until their maturation is sufficiently completed. There is little knowledge about why some reticulocytes are sequestered in the spleen, while others are not.

Daily hot‐water immersion preserves altitude‐induced haemoglobin mass expansion following descent independent of erythropoietin

Experimental Physiology, EarlyView.
Abstract High‐altitude exposure increases haemoglobin mass (Hbmass), a key determinant of arterial oxygen‐carrying capacity, but following descent this adaptation can regress toward baseline within 7 days. Long‐term heat acclimation has emerged as an alternative stimulus for Hbmass expansion; however, whether post‐altitude passive‐heat exposure can ...

Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

The Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Endocrine and androgenic response to altitude training in professional cyclists

The Journal of Physiology, EarlyView.
Abstract figure legend Steroidal and endocrine variables are altered during altitude training. Abstract This study investigated endocrine and steroidal blood markers in 31 male elite cyclists monitored over 7 weeks, including a 3 week altitude training camp either at 2050 m (n = 19) or 3000 m (n = 12).

Relationship between erythropoietin levels and reticulocyte count in sports

Slovak Journal of Sport Science
The aim of the study was to determine if a direct relationship could be established between erythropoietin levels and reticulocyte counts in blood samples collected at the same time.

Augmenting erythropoiesis using recombinant human erythropoietin at sea level blunts the high altitude induced increase in erythropoiesis

The Journal of Physiology, EarlyView.
Abstract figure legend Pharmacologically augmenting erythropoiesis with rEPO at sea level blunts the high altitude induced erythropoiesis. Abstract Erythropoiesis increases with high altitude (HA) acclimatization. Recombinant human erythropoietin (rEPO) induces erythropoiesis.

Insights from lipidomics into the terminal maturation of circulating human reticulocytes

Cell Death Discovery
In the age of “omics”, lipidomics of erythropoiesis is still missing. How reticulocytes mature in the circulation into functional erythrocytes is also largely unknown.

Long‐term passive heat acclimation enhances maximal oxygen consumption via haematological and cardiac adaptation in endurance runners

The Journal of Physiology, EarlyView.
Abstract Figure Legend Endurance‐trained runners completed a 5‐week hot‐water‐immersion (HWI) intervention (≥40°C, 45 min, five sessions per week) and a training‐matched control period in a cross‐over design. HWI induced a 33 g increase in haemoglobin mass (Hbmass) and a 10 mL expansion in left‐ventricular end‐diastolic volume (LVEDV), resulting in a 2.

THE IN VITRO INCORPORATION OF RADIOACTIVE PHOSPHATE INTO RABBIT RETICULOCYTES

, 1952
Suspensions of rabbit red blood cells containing a high percentage of reticulocytes were obtained by the method of successive daily bleedings. When radioactive phosphorus in the form of inorganic phosphate was added in vitro to such suspensions, the ...
