Effects of Inorganic Arsenic on Bone Marrow Hematopoietic Cells: An Emphasis on Apoptosis and Sca-1/c-Kit Positive Population.
We have evaluated the impact of arsenic, on blood and blood forming cells by the changes in their cellular morphology, immune functional capacity, alteration of bone marrow CD34 positive stem/progenitors and changes in the phenotype of Sca-1, c-Kit dual positive primitive stem cell population. The s...
[Robotized microscopy introduces the test quality standard for blood smears].
The authors consider recommendations on blood smear microscopic tests, possibilities of implementing these recommendations when manual microscopy and automatic microscopy complexes (AMC) are used. Whether one may switch over from the recommendations to the quality standard implemented in practice wh...
[Impedance frequency properties of rabbit whole blood cells].
The impedance amplitude and phase angle of rabbit blood cells was frequency-dependent. The impedance spectrum of rabbit blood cells had two characteristic frequencies: the 1st one (f(C1)) was 2.58 MHz, the 2nd one (f(C2)) was 5.21 MHz. CONCLUSION: The frequency properties of whole blood cells can be...
Effect of aspirin treatment on TNF@a production by women with a history of preterm birth
We conclude that endotoxin responsiveness of women with a history of preterm birth is similar to that of women with a history of term birth in terms of in vitro TNFalpha production. Aspirin increases TNFalpha production by PBML in control women but not in women with a history of preterm birth. The d...
Induction of apoptosis by monosaccharide butyrate stable derivatives in chronic lymphocytic leukemia cells.
Monosaccharide butyrate stable derivatives are potent inducers of primary CLL cell apoptosis, both in untreated and alkylating agent pre-treated cases. Our results suggest that the apoptotic pathways elicited by butyrate in CLL lymphocytes are direct, specific and most probably do not involve bcl2/b...
Detection and analysis of apoptosis in peripheral blood cells from breast cancer patients.
I and grade II tumors. These observations may reflect the immunosuppression characteristic of some breast cancer patients, which may contribute to tumor growth. Therefore, further studies are necessary to elucidate the factor(s) involved in such massive blood cell death....
[The cytogenetic effect in a group of settlers from a 30-kilometer area of right of way].
One of the critical human group of potential risk is the group of population from 30-km zone around the Chernobyl nuclear power plant. The cytogenetical examination of 12 persons (8 man, 4 woman, 30-60 years old) from 5 villages situated in north-west and south-east directions from the ChNPP in the...
Influence of photoperiod on immune cell functions in the male Siberian hamster.
The present study tested the hypothesis that immune cell function is influenced by ambient photoperiod. The male Siberian hamster served as the experimental model because day length regulates a variety of seasonal adaptations in physiology. Adult hamsters were in long days (16 h of light daily), whi...
Mcl-1 in transgenic mice promotes survival in a spectrum of hematopoietic cell types and immortalization in the myeloid lineage.
Mcl-1 is a member of the Bcl-2 family that is expressed in early monocyte differentiation and that can promote viability on transfection into immature myeloid cells. However, the effects of Mcl-1 are generally short lived compared with those of Bcl-2 and are not obvious in some transfectants. To fur...
