It is well known that lightning produces NOx as a result of the high temperatures in discharge channels. Since most viable proposed electrification mechanisms involve ice crystals, it is reasonable to assume that lightning discharge channels frequent

It has been suggested that cancer ought to be regarded as a disease of cell differentiation. In multicellular organisms, indeed, the control of cell multiplication is linked to cell specialization: During the process of differentiation embryonic cell

The common assumption that the seed failure in interploidy crosses of flowering plants is due to parental genomic imprinting is based on vague interpretations and needs reevaluation since the general question is involved, how differentiation is timed

Various observations suggest that an intracellular timer is involved in the control of cell proliferation and differentiation that supplements control by extracellular signaling and depends on quantitative relations between cytoplasm and nucleus. To

Terminally differentiated cells usually do not divide and are, thus, reproductively dead. To elucidate the significance of radiation-enhanced differentiation to reproductive cell death, murine erythroid progenitor cells were gamma-irradiated in plasm

Various agents have been shown to induce differentiation in neoplastic cells. The present study aimed at investigating comparable phenomena induced by high doses of γ-irradiation in the presence of physiological factors. The erythroleukemic K562 cel

The effect of a leukemia-inducing treatment on early changes in kinetic parameters of murine bone marrow cells were investigated. Mice were treated i.p. one, four and eight times at bi-weekly intervals with 1 mg DMBA. Up to nine weeks after the last

Transplantation of bone marrow cells of magnetic-field-exposed mice led to increased numbers of spleen colonies (CFU-S 7d) in conditioned recipient mice (Peterson et al. 1986). Here we report on the dependence of this phenomenon on body temperature,

In order to analyze the effect of various kinds of radiation on the terminal differentiation processes of fibroblasts in culture, both human skin and lung fibroblasts were irradiated with electromagnetic non ionizing as well as ionizing radiation in

Observations from 4928 matings made over 17 years were used to evaluate the influence of year, exposure class, cow weight, average daily gain (ADG) before and during the breeding season on pregnancy rate (PR) and calving date (CD) in four breeds of b
