It has been described that fish nucleated red blood cells (RBCs) Background: generate a wide variety of immune-related gene transcripts when viruses highly replicate inside them and are their main target cell. The immune response and mechanisms of fish RBCs against viruses targeting other cells or tissues has not yet been explored and is the objective of our study. Rainbow trout RBCs were obtai...

Recently, using immunohistochemical methods, we surprisingly found that endoplasmic reticulum glucose-6-phosphatase is present in human embryonic and fetal red blood cells (RBCs) but not in adult RBCs. The fact that an endoplasmic reticulum enzyme, whose major site of expression in adults is the liver, is present in human embryonic and fetal RBCs, particularly nucleated cells, indicated that it...

OBJECTIVES Atypical nucleated RBCs (NRBCs) found on several patient blood smears between 2010 and 2012 were noted to resemble avian RBCs. NRBCs are not normally found in the circulation beyond the neonatal period and may indicate hematologic disease, malignancy in the bone marrow, or other severe conditions. Our blood smears with unusual NRBCs did not contain other abnormalities that typically ...

In many multicellular organisms, oxygen is transported by respiratory proteins, which are globins in vertebrates, between respiratory organs and tissues. In jawed vertebrates, eight globins are known which are expressed in a highly tissue-specific manner. Until now, hemoglobin (Hb) had been agreed to be the only globin expressed in vertebrate erythrocytes. Here, we investigate for the first tim...

In the last decade it has become clear that, similarly to nucleated cells, enucleated red blood cells (RBCs) are susceptible to programmed apoptotic cell death. Erythrocytic apoptosis seems to play a role in physiological clearance of aged RBCs, but it may also be implicated in anemia of different etiological sources including drug therapy and infectious diseases. In malaria, severe anemia is a...

BACKGROUND Information on the prognostic utility of the admission complete blood count (CBC) and differential count is lacking. OBJECTIVE To identify independent predictors of mortality from the varied number and morphology of cells in the complete blood count defined as a hemogram, automated five cell differential count and manual differential count. DESIGN Retrospective cohort study and c...

Various species of Trypanosoma parasites are known to infect several wild and domestic animals worldwide. A 7-year-old Holstein cow from Baneh, Kurdistan province, was examined by a private veterinarian due to anorexia and depression. Physical examination revealed fever, enlarged subscapular lymph node, and pale mucosa. Blood samples were taken for hemato-logical, parasitological, and ...

BACKGROUND Survival and colony formation by transplanted tissue derived connective tissue progenitor cells (CTPs) are thought to be important factors in the success of clinical tissue engineering strategies for bone regeneration. Transplantation of cells into defects larger than a few millimeters expose cells to a profoundly hypoxic environment. This study tested the hypothesis that delaying th...
