The reactivation of chicken erythrocyte nuclei in chick-mammalian heterokaryons resulted in the activation of chick globin gene expression. However, the level of chick globin synthesis was dependent on the mammalian parental cell type. The level of globin synthesis was high in chick erythrocyte-rat L6 myoblast heterokaryons but was 10-fold lower in chick erythrocyte-mouse A9 cell heterokaryons....

The objective of the present work was to study the effects of erythrocyte proteins phosphorylation in erythrocyte aggregation and deformability. Human whole blood samples were incubated in vitro in absent and in presence of the phosphorylation/dephosphorilation band 3 inhibitors and also with adenylyl cyclase, guanylate cyclase and PI3K inhibitors and the erythrocyte aggregation index (AIE) and...

Adaptive mechanisms to hematocrit levels of 0.9 in our erythropoietin-overexpressing mice (tg6) include increased plasma nitric oxide levels and erythrocyte flexibility. Doubled reticulocyte counts in tg6 suggest an increased erythrocyte turnover. Here we show that compared with wild-type (wt) animals, erythrocyte lifespan in tg6 is 70% lower in tg6 mice. Transgenic mice have a younger erythroc...

T0M0KUNI, K. Effects of Lead Exposure on the Activity of Erythrocyte Pyrimidine 5'-Nucleotidase and s-Aminolevulinic Acid Dehydratase in Mice. Tohoku J. exp. Med., 1983, 139 (1), 27-32 The effects of lead exposure on the activities of erythrocyte pyrimidine 5'-nucleotidase (Py5N) and s-aminolevulinic acid dehydratase (ALA-D) were investigated in the mice given ad libitum the drinking water cont...

We analyzed erythrocyte membrane C26:0 from 504 volunteers by high-performance liquid chromatography. The associations between the elevated levels of erythrocyte membrane C26:0 (0.20 or greater than 0.20%) and sex, obesity (body mass index> or =26.4), smoking (> or =20 cigarettes per day), present illnesses and past diseases were examined with the chi(2) test. The correlations among age and the...

We studied sea-level residents during 13 days of altitude acclimatization to determine 1) altitude acclimatization effects on erythrocyte volume and plasma volume, 2) if exogenous erythrocyte volume expansion alters subsequent erythrocyte volume and plasma volume adaptations, 3) if an increased blood oxygen content alters erythropoietin responses during altitude acclimatization, and 4) mechanis...

PURPOSE Chronic inflammation induces cancer and cancer induces local tissue damage with systemic inflammation. Therefore, the aim of this study is to investigate the potential relationship between the severity of inflammation and prognosis in cancer patients. MATERIALS AND METHODS This study enrolled 220 patients from January 2002 to December 2006 who underwent gastric surgery. We evaluated t...

Suitable physiological condition in fishes for the selection of broodfishes can be achieved through hematological studies. The present study aimed to examin the hematological indices in Juvenile Sturgeons at different stages of growth. Total albumin content in blood serum, hemoglobin concentration, the erythrocyte and leukocyte count of 54 sturgeon specimens (Persian sturgeon Acipenser persicus...

To examine the relationship between body mass index, blood pressure, and the Na+,K+-adenosine triphosphatase (ATPase) system, we measured the erythrocyte ghost Na+,K+-ATPase and the erythrocyte Na+ concentration in 120 blacks and 127 whites (136 males and 111 females). Blacks showed a 13.9% higher erythrocyte Na+ (7.63 +/- 0.19 vs 6.70 +/- 0.11 [SEM] mEq/L; p = 0.0001) and a 16.1% lower erythro...
