Bovine herpesvirus 1 (BoHV-1) is widely distributed among cattle populations and has been associated with cells, fluids, and tissues collected from donor animals for use in reproductive technologies. The purpose of this study was to determine if lactoferrin would inhibit BoHV-1 in cell culture and to evaluate if embryos could develop normally when cultured in vitro with lactoferrin. In Experime...

BACKGROUND Cord blood transplant is an accepted treatment for many malignant and non-malignant diseases. We sought to determine the feasibility of collecting cord blood in Jordan and the effect of maternal and fetal factors on the quality of the cord blood units. METHODS A total of 124 cord blood units were collected, and 75 (60%) cord blood units were included in this analysis. Cord blood vo...

Phosphatidylserine (PS) externalization is a marker for the nucleated cell apoptosis, and refers cellular activation rather than apoptosis in platelets. On the other hand, several similarities exist between platelet activation and apoptosis in nucleated cells. Herewith we investigated the relationship between platelet activation and platelet apoptosis. Platelets isolated from fresh blood of 22 ...

Lipid-soluble spin labels were incorporated into human lymphocytes and mouse L-cells and the resulting electron spin resonance spectra were compared with spectra obtained from similarly labeled human erythrocytes. Spin labels were found in all subcellular fractions of the nucleated cells that contained membranes. Spinlabeled cells remained viable and capable of replicating in vitro. Electron sp...

Blood slides of a 70-yr-old woman branes around a central “core.” The with lymphosarcoma cell leukemia ribosomal nature of this structure is showed 10#{176}/o-40#{176}/o notched-split nuevidenced by: (1) similarity of the parcleated lymphocytes. A few round, tides ot ribosomes, (2) the structure’s nucleated lymphocytes contained a connections with endoplasmic reticuround or oval body close to t...

Erythroid cells constitute a model particularly suitable for study of the relationship between cell maturation and nucleic acid and protein synthesis. Circulating reticulocytes, nonnucleated cells capable of prolonged protein synthesis, are derived from cells in the bone marrow that proceed from an apparently multipotential nucleated stem cell through various stages of increasingly mature or di...

A chloramphenicol-resistant mutant, isolated from mouse A9 cells, was enucleated and fused with a nucleated chloramphenicol-sensitive mouse cell line. Resultant fusion products, cytoplasmic hybrids (or "cybrids"), were selected as resistant to chloramphenicol, and had the nuclear markers and chromosome complement of the chloramphenicol-sensitive parent. These cybrids appeared at the high freque...

The sera of three patients with malignant melanoma showing reactivity with surface antigens of cultured autologous melanoma cells were analyzed by mixed hemadsorption and immune adherence assays in conjunction with absorption tests. In contrast to the melanoma-specific antigens demonstrated previously, the surface antigens detected by these sera occurred on a broad range of nucleated cells, bot...

Recovery of bone marrow cellularity, CFU-C, and CFU-S were studied sequentially over 90 days time after syngeneic bone marrow transplantation in mice. A minimal cell dose of 2 X 10(5) bone marrow cells was given. At day 28 after transplantation, CFU-C reached more than 50% of the normal range whereas the CFU-S concentration was less than 15%. Normalization of CFU-S occurred at day 90. The effec...
