Morphological characterization of cell death during the ovary differentiation in worker honey bee
(Elsevier B.V., 2002-01-01)
Cell death that occurs during ovary differentiation in the honeybee worker's larval development accounts for ovariole reabsorption. From a morphological standpoint, three modes of death were detected. Germinative cells in ...
Cell death in ovarioles causes permanent sterility in Frieseomelitta varia worker bees
(1999-12-01)
Frieseomelitta varia worker bees do not lay eggs even when living in queenless colonies, a condition that favors ovary development and oviposition in the majority of highly social bees. The permanent sterility of these ...
Effects of acetylsalicylic acid and acetic acid solutions in VX2 carcinoma cells. In vitro analysis
(2006-05-01)
Purpose: To analyze, in vitro, the effects of acetylsalicylic acid (aspirin) and acetic acid solutions on VX2 carcinoma cells in suspension and to examine the correlation between these effects and neoplastic cell death. ...
A new nucleolar body appears in Drosophila saltans salivary gland cells before histolysis, in programmed cell death
(Univ Arizona, 2006-12-05)
The salivary glands of Drosophila saltans ( saltans group, saltans subgroup) analyzed in an advanced stage of programmed cell death showed the appearance of a single, round, nucleolar corpuscle inside the highly altered ...
Ultrastructural analysis of the effect of mating delay on cell death in the ovaries of virgin honey bee (Apis mellifera L.) queens
(Int Bee Research Assoc, 2009-01-01)
This paper reports the effect of mating delay on the ovaries of virgin Apis mellifera queens using analysis by light and electron microscopy. The results showed that the terminal filament did not change throughout the study ...
Cell death evaluation in benzo[a]pyrene-transformed human breast epithelial cells after microcell-mediated transfer of chromosomes 11 and 17
(Elsevier B.V., 2004-02-26)
The incidence of apoptosis and nuclear instability, including the incidence of catastrophic death, were investigated in benzo[a]pyrene (BP)-transformed human breast epithelial cells (BP1-E cell line) after microcell-mediated ...
Cell death and the immune response of the sipunculid worm Themiste petricola
(University of Modena and Reggio Emilia, 2010-09)
We have recently studied the role of cell death in the immune system of the sipunculan worm Themiste petricola. Typical biochemical and morphological changes of apoptosis were induced in celomocytes of these marine worms ...
Transient receptor potential melastatin 4 inhibition prevents lipopolysaccharide-induced endothelial cell death
(2011)
Aims Endothelial dysfunction is decisive in the progression of cardiovascular diseases. Lipopolysaccharide (LPS)-induced reactive oxygen species (ROS)-mediated endothelial cell death is a main feature observed in inflammation ...
